Flooring, floor materials / solid wood flooring, parquet, laminate flooring, bamboo flooring, cork flooring
The main varieties of flooring are solid wood flooring (lacquered board and plain plate), solid wood flooring, laminate flooring. There are also bamboo flooring and cork flooring.
(A) solid wood flooring
Solid wood flooring is made of wood after drying, processed after the formation of ground decoration materials. It has a natural pattern, comfortable feet, the use of safe features, is the bedroom, living room, study and other ground decoration of the ideal material. Solid wood decoration style back to nature, texture, natural, in the forest coverage rate, and vigorously promote environmental protection today, solid wood flooring is even more precious. Solid wood floor AA grade, A grade, B grade three grades, AA grade the highest quality.
Solid wood flooring standards are GB / T15306-2001. The standard since May 1, 2002 from the implementation of the original 94 standard at the same time be replaced. The new national standard made important changes and supplements to the old national standard. Mainly to modify the size and defects of some of the contents of the application of the tree to add the specification and the requirements of the paint board. While eliminating the need for wood impact toughness hardness and wear resistance requirements.
In the past the name of the market once the name of chaos standard, the name of strange, as well as fake and shoddy mixed during what, what gold grapefruit, gold does not change, rich wood, so that customers really difficult to distinguish, So the new standard must be strictly marked, and the form of appendix. Sales should be issued by the authority of the test report shall prevail.
1. Solid wood flooring main tree species
Solid wood flooring due to different materials, its hardness, natural color and texture differences are also large, generally have the following:
Quercus (oak), pear, heavy ants wood (Ibis), borneol incense (camphor) incense two winged beans, Gamba pair, Baodi beans, Pontianaki camphor (iron wood), mountain wood and so on.
Medium: teak, Indian eggplant (pineapple grid), Saul double (Palau), tea tea cornel (rue).
Soft: Ash, birch. Www.snren.com
Light: Fagus (beech), birch, mountain lumber.
Middle color: Quercus acutissima, Ash, Saul double, tea tea cornelia.
Dark: teak, Indian eggplant, heavy ants wood, incense two winged beans, wood pod beans (goods card more).
Rough: teak, quercus, gibbata, ash.
Fine lines: Fagus, birch.
2. Solid wood floor moisture content
There are three forms of water in the wood, one is in the cell cavity and cell gap in the water, that is, the water in the capillary, known as free water. The second is absorbed by the cell wall of water, known as the adsorption of water. The third is the composition of cell tissue water, known as chemical water.
When the wet wood moisture evaporates, the first loss of free water, when the free water evaporates and the water is still saturated when the water content, known as the fiber saturation point moisture content.
Fiber saturation point is the turning point of wood performance, above the fiber saturation point, the strength of the wood is constant, does not change with the water content changes. At the same time the wood did not shrink this volume change. When the water content falls below the fiber saturation point, that is, the adsorption of water in the cell wall began to evaporate, the strength increases with the water content decreased, and the phenomenon of wet expansion and contraction is also apparent. Different wood fiber saturation point moisture content of about 22% to 33%.
Nature in the region of the humidity and temperature in different seasons have a relatively stable. Wood in a long time in this relative temperature and humidity environment, the moisture content will reach a relatively constant. At this time the moisture content is called the equilibrium moisture content (for example, the annual balance of water content in Shanghai is 4.6%).
The equilibrium moisture content of the wood varies with the temperature and humidity of the environment in which they are located, and tends to approach the environment when there is a difference between the equilibrium moisture content and the ambient humidity. This produces a wet bulge and shrinkage of wood, which is a unique physical phenomenon of wood.
The wood is also an anisotropic body. The actual use of wood in the water content of the fiber saturation point below, so the main gain and loss of water is the adsorption of water on the cell wall. The vast majority of the cells of the wood are grown longitudinally, and their swelling is perpendicular to the cell wall. As a floor, we can find that there is no general expansion and contraction in the longitudinal direction, and the expansion ratio in the width direction is generally 3% ~ 6% (refers to the wood moisture content in the fiber saturation point below the moisture content changes).
It can be seen that it is important to control the moisture content of the floor. Not only in the production must pay attention to, in the laying of more attention should not be made to deformation of the floor damp.
3. Solid wood floor dry balance treatment purposes
(1) to achieve the required adaptation of the use of regional environmental characteristics of the equilibrium moisture content.
(2) to eliminate the wood in the growth and processing process exists and produce internal stress.
(3) to adjust and restore the deformation.
As the Shanghai annual water balance of 15.6%, so the water content for the floor in Shanghai should be controlled at 10% to 14%.
process
(1) natural dry, about 30 to 40 days, so that the moisture content of about 30%.
(2) artificial drying, about 10 to 30 days, so that the water content of 10% or less. This process also makes the pulp within the wood distilled out, balanced wood cell wall tissue, shrinkage performance tends to be consistent.
(3) health treatment, about 10 to 20 days. Through this process finally reached the three purposes of wood drying.
The drying balance treatment is the so-called heat treatment. The length of this process will vary depending on the material, but it can not be artificially shortened. There is a wrong saying in the sale, that is, after the heat treatment of the floor is "never deformation". In fact this is not possible, no matter how the treatment, the wood in the fiber saturation point below the moisture content changes in the emergence of the wet expansion and contraction phenomenon is inevitable
4. Reason for deformation of solid wood flooring
Generally speaking, there are more phenomena in the use of the floor was tile-like or arch, which is due to the floor due to moisture, the reasons for the floor damp generally have the following:
(1) moisture in the air (eg, yellow plum).
(2) floor is not dry, with cement reinforcement keel.
(3) keel, wool floor too wet.
(4) the use of water-based glue.
(5) the first floor and other humid environment without special moisture treatment.
(6) stone floor and floor of the cross section is not closed for treatment.
(7) blisters (such as water pipes rupture, balcony water pouring, etc.).
In addition, the product itself and improper construction can also cause arch. Such as improper drying, lack of health, moisture content is too low, the back slot is too shallow, the construction of the expansion of the gap is not enough feet, laying too tight and so on.
5. Solid wood flooring laying and maintenance points
(1) the floor should be laid in the late construction, not cross construction. After laying should be polished and painted as soon as possible. So as not to stain the floor or make the damp deformation.
(2) before the laying of the floor should be unpacked piled on the laying of the site 1 to 2 days, to adapt to the environment, so as to avoid the emergence of swelling and deformation after laying.
(3) laying should be done moisture-proof measures, especially the bottom of the more humid occasions. Moisture measures are covered with moisture-proof paint, shop moisture-proof film, the use of bedding Po and so on.
(4) keel should be flat and firm, avoid using cement reinforcement, preferably with expansion bolts, the United States and other fixed nails.
(5) keel should be used to lobing strong larch, Liu and other wood. The moisture content of the keel or wool floor shall be close to the moisture content of the floor. Keel spacing should not be too big, generally not more than 30 cm. Both ends of the floor should be implemented on the keel, not empty, and each keel must nail nails. Do not use water-based glue.
(6) the floor should not be too tight shop, should be enough to stretch around the expansion joints (0.5 to 1.2 cm), and should not be wide laying, in case of wider occasions should be separated from the cut, and then pressure copper transition.
(7) floor and hall, bathroom, kitchen and other stone ground junction should be a thorough isolation of moisture-proof measures.
(8) floor color is inevitable, such as the color requirements are higher, can be pre-sorted, take a gradual transition method to reduce the visual sense of mutation.
(9) in the use of bogey water rinse, to avoid prolonged sun, air conditioning continuous straight blow, the window to prevent rain forest, to avoid hard objects hit friction. To protect the floor, wax can be painted on the paint (from the perspective of the protection of the floor, waxing better than the paint).
6. Paint the floor
Paint decorated floor made by the factory in the assembly line, most of the paint used for the UV paint to UV fast curing, its hardness and wear resistance are much higher than ordinary hand paint, but slightly less adhesion.
Another advantage of the floor is that the entire floor is made up of many quick lacquers and therefore does not crack with the shrinkage of the floor.
(2) solid wood flooring
Solid wood composite flooring, is the high-quality solid wood sawing cut into the surface panels, core board and floor monolithic, and then according to the different types of materials, mechanical principles of the three monolithic in accordance with the vertical, horizontal, vertical three-dimensional arrangement, with glue paste , And pressed at high temperature into a plate, which makes the wood of the different changes in control. As the surface of the film surface glossy glossy, and wear, heat, impact resistance, flame retardant, mildew, moth, etc., laying in the room, not only make the room more coordinated, more perfect, and its price than similar Solid wood flooring is high, and thus more and more welcomed by consumers.
At present, the solid wood composite floor has three layers and two layers.
Three-layer solid wood flooring surface for the quality of valuable wood flakes, the middle and the bottom for the fast-growing wood, made of hot glue. Surface thickness of about 4 mm core layer in 8 to 9 mm, the bottom 2 mm or so, the total thickness of the general are 14 to 15 mm.
Multi-layer solid wood composite flooring to multi-layer plywood as the substrate, the surface of hard wood chips inlaid plywood or sliced veneer, made of hot glue. The number of layers of the plywood must be three or five layers, usually hardwood, 1.2 mm in thickness, 0.2 to 0.8 mm in planed plates, and generally no more than 12 mm in total thickness.
Solid wood flooring with solid wood flooring natural beauty, foot comfort, sound insulation and other advantages, while overcoming the shortcomings of solid wood flooring deformation (each layer of wood fibers perpendicular to each other, the dispersion of the deformation and stress). And specifications, easy to lay.
The drawback is that if the quality of the glue is poor, there will be degumming. In addition, because the surface is thin (especially multi-layer)), the use must pay attention to maintenance. So the use of occasions are limited.
Solid wood composite flooring between the glue glue, the size of its formaldehyde emission is a very important indicator. The state has a mandatory standard, that is, GB18580-2001 "interior decoration materials, wood-based panels and their products formaldehyde release limit." The standard requirements of solid wood flooring must meet the E1 level requirements (formaldehyde emission ≤ 1.5mg / L) and in the product logo on the express.
(C) to strengthen the composite floor (impregnated paper laminated wooden floor)
Structure: Reinforced composite flooring consists of four layers.
First layer: wear layer. Mainly composed of Al2O3 (aluminum oxide), has a strong wear resistance and hardness, some of the melamine composition of the laminate flooring can not meet the requirements of the standard.
The second layer: decorative layer. Is a layer of resin impregnated with melamine resin, paper printed with imitation of precious wood species of wood or other patterns.
The third layer: grassroots. Is a medium density or high density laminate. By high temperature, high pressure treatment, there is a certain moisture, flame retardant properties, the basic material is wood fiber.
The fourth layer: balance layer. It is a layer of kraft paper, have a certain strength and thickness, and dipped in resin, play a role in moisture deformation of the floor.
Main quality indicators
Surface wear speed
Public places with ≥ 9000 turn, the family with ≥ 6000 turn. The above number of revolutions refers to the initial grinding, that is, the appearance of the surface trim, rather than wear the final value of the floor all wear.
The market is some reinforced composite floor express the high number of wear-resistant, but is likely to be the ultimate value of the end of wear.
Absorbance Thickness The expansion rate refers to the degree of increase in the thickness of the base layer after a period of time after the strengthening of the composite floor soak in water at 25 ° C. The greater the expansion rate, the greater the strength of the floor after damp, and the emergence of surface protrusions or even fall off, seriously affecting the service life. The current market price of various brands of its expansion of the thickness of the size of the difference can be more than ten times.
Surface impact resistance
That is, the method of the impact of the floor on the test, the impact of the size of the pit is left behind the impact of good or bad impact, the smaller the diameter, the better the impact resistance, long service life. Strengthen the composite floor wear layer thickness of 0.1 mm or more, up to 0.7 mm thick.
Formaldehyde emission
According to GB18580-2001 regulations to strengthen the composite floor is directly used for indoor products, so the formaldehyde emission must reach E1 level, that is ≤ 0.12mg / L.
In addition to this there are static bending strength, internal bonding strength, density, moisture content, bonding strength and other indicators. Sales should be clear that its wear resistance and formaldehyde limit level.
Strengthen the advantages and disadvantages of composite flooring:
advantage
Wear: about 10 to 30 times more than ordinary paint floor.
Beautiful: available computer simulation of a variety of grain and pattern, color.
Stable: completely break the original wood of the organization, destruction of the anisotropy and wet expansion and contraction characteristics, the size is very stable, especially for the floor to warm the room.
In addition, there are impact, anti-static, resistant to pollution, light resistance, resistance to burning cigarettes, easy installation, maintenance and simple.
Disadvantages
Blister damage can not be repaired, foot feeling worse.
In particular, it is pointed out that there have been dealers in the past that strengthen the composite floor is "waterproof floor", which is only for the surface, in fact, strengthen the use of composite flooring only to avoid the blisters.
Solid wood flooring, laminate flooring is currently all by the supplier responsible for laying.
(D) bamboo flooring
Bamboo flooring is developed in recent years, a new type of building decoration materials, it is natural high-quality bamboo as raw material, after 20 procedures, off the bamboo juice, high temperature and pressure pressure, and then after 3 layers of paint , The last infrared drying. Bamboo flooring with its natural advantages and after forming a number of excellent performance to the building materials market to bring a green fresh wind.
Bamboo flooring has a natural texture of bamboo, fresh and elegant, giving a return to nature, elegant and refined feeling. It has many characteristics, first bamboo flooring to bamboo wood, with the original characteristics of wood, and bamboo in the processing process, in line with national standards of high quality rubber species, to avoid formaldehyde and other substances on the human body hazards, as well as bamboo flooring The use of advanced equipment and technology, through the original bamboo 26 process processing, and has a natural wood floor of the natural beauty and ceramic tiles durable.
Bamboo flooring to buy
China's bamboo flooring development history is not long, only eight or nine years of history. Began to scale into the market is in recent years, but because of the unique characteristics: texture straight, elegant tones, "rather eat no meat, can not live without bamboo" reputation. Coupled with the production process of artificial selection, so that bamboo floor size and stability, good mechanical strength, durable Durable, from the natural, with natural, non-polluting, but also for the room to add more cultural tastes, won the domestic and foreign consumers love. However, due to bamboo flooring processing and production industry management is not standardized, between the technical equipment and production management gap between the large, therefore, consumers in the purchase, the following points for the purchase of reference.
1, product information is complete
In general, the formal product country expressly stipulates that there should be a complete set of product information, including the manufacturer, brand, product standard, inspection grade, instructions, after-sales service and other information, complete information products, indicating that the production enterprises are a certain scale of formal enterprises , Even if there are problems consumers are well documented.
2, the appearance of the product quality
Bamboo flooring appearance
First view of its floor color: color floor color golden yellow, whole body translucent; carbonized bamboo flooring is bronze or brown, uniform color and glossy.
Paint quality: the floor placed in the light benefits to see whether the surface of the bubble, pitting, orange peel phenomenon, look at the paint is rich, full, smooth.
3, intrinsic quality
First look at the material, can be hand and eye view, if the floor in the hands of the lighter, indicating the use of tender bamboo; if the eye view of the blurred texture, indicating that the bamboo is not fresh is more old bamboo.
View whether the symmetrical balance of the floor structure: from the bamboo floor at both ends of the cross, whether to meet the principle of symmetrical balance, if the structure is stable.
Floor layer and interlayer glue is tight: with both hands breaking, whether there will be layered.
4, processing accuracy
Bamboo flooring processing accuracy, can be random sampling, the method is to take any number of flooring, placed on the flat surface of the tenon, groove together, if the structure is stable.
Bamboo flooring flooring
Bamboo flooring laying and solid wood mouth floor laying the same way, the use of keel laying method (see solid wood flooring laying) in this does not repeat.
Bamboo flooring maintenance
The correct use and maintenance of bamboo flooring is to extend the life of the key, in recent years, due to some users of bamboo flooring improper use, causing some quality problems and complaints, in this case, both dealers or enterprises do a good job after-sales service ,with
Also need to promote the use of consumer knowledge, maintenance.
Bamboo flooring in use should pay attention to the following:
1, to maintain indoor dry humidity
Although the bamboo flooring after drying, reducing the size of the change, but because of its bamboo material is natural, so it will change with the climate and humidity and deformation.
In the northern region of the dry season, especially in the open heating, the indoor can be adjusted by different methods such as the use of humidifier or heating on the basin of water; in the southern region of yellow croaker season, window ventilation, keep the room dry.
To this end, indoors should try to avoid sun exposure and rain wet, if the water should be promptly dry. Www.snren.com
2, to avoid damage to the floor surface bamboo floor paint, should avoid hard objects impact, sharp weapon scratches, metal friction and so on.
3, the correct clean the floor in the daily use of the process, keep the ground clean, clean, you can use a clean sweep sweep, and then wring dry mop dragged a new look. If conditions permit, two to three months to play a floor wax, so better.
(5) cork flooring
Cork flooring is called "floor pyramid tip consumption". Cork is grown on the Mediterranean coast of oak, and cork products is the raw material of oak bark, compared with solid wood flooring more environmentally friendly, sound insulation, moisture effect will be better, to give people excellent foot feeling. Cork soft, quiet, comfortable, wearable, accidental fall of the elderly and children, can provide a great buffer effect, its unique sound absorption and thermal insulation performance is also very suitable for the bedroom, conference room, library, recording Shed and other places.
The category of cork flooring
Cork flooring is divided into five categories as follows:
The first category: cork flooring surface without any cover, this product is the earliest.
The second category: in the cork surface for painting. That is, in the surface of cemented cork painted UV varnish or paint or varnish PVA. According to different paint, can be divided into three kinds, namely, high light, matt and light. This is the 90's technology, such products on the surface of the cork surface surface is relatively high, that is, the use of soft wood is more pure.
The third category: PVC veneer, that is, in the cork surface covered with PVC veneer, its structure is usually four:
The thickness of the surface is 0.45mm; the second layer of natural cork decorative layer thickness of 0.8mm; the third layer of cemented softwood layer thickness of 1.8mm; the bottom of the stress balance and waterproof PVC layer, this A layer is very important, if no such layer, when the material when the material heat solid, PVC surface cooling shrinkage, will make the whole floor warpage.
This type of floor is currently favored by consumers in Beijing and Shanghai.
The second layer of natural veneer, the thickness of 0.45mm; the third layer of cemented cork, the thickness of about 2mm; the bottom of the PVC board and the third category of the same Waterproof and good, while the plate surface stress balance, the thickness of about 0.2mm.
The fifth category: plastic cork flooring, resin cemented cork flooring, rubber cork flooring. Www.snren.com
According to the room can choose different categories:
General family can choose the first and second category, because the first category of the most primitive, but its excellent function can all show that the second category of cork flooring, cork layer slightly thick, pure texture, but the layer is only 0.1mm-0.2mm thick , Thin, but the soft, high-strength wear-resistant layer will not affect the excellent performance of the softwood. Although the surface is thin, but the family is more careful, therefore, will not affect the service life, and easy to lay, consumers as long as the release of the isolation paper can be directly stick to the clean dry concrete floor.
Shops, libraries and other large flow of occasions, can choose the second, three types of flooring. Www.snren.com
As the second and third types of materials, the table has a thick (0.45mm) flexible wear-resistant layer, although the sand will be brought to the surface of cork flooring, and pressed into the wear-resistant layer will not slide, when the foot away from the sand will Is pop, will not break through the wear layer, so the flow is large, but does not affect the floor surface.
Such as elasticity, vibration absorption, sound absorption, sound insulation and other properties are also very good, but usually rubber smell, so this floor to change its surface, in its surface with the use of rubber, PU or PUA high wear-resistant layer for the protective layer to eliminate the smell, but also wear.
Cork floor density:
Cork floor density is divided into three 400kg-450kg / m3; 450kg-500kg / m3; greater than 500kg / m3. General household selection 400kg-450kg / m3 enough, if the room has heavy objects, optional slightly higher, in short, can choose the density of small as far as possible selected density is small, because of its better flexibility, insulation, sound absorption, vibration and other properties.
Cork floor quality
Cork flooring selection first look
Whether the surface of the floor sanding smooth, with or without drum particles, cork particles are pure.
Select the edge of the floor is straight, the method is: take four pieces of the same floor, shop on the glass, or more flat on the ground, assembled to see whether it is fit.
Check the bending strength of the board, the method is to split the two diagonal corners of the floor, the view of its curved surface cracks, no quality products.
Gluing strength test.
Will be small pieces of style into the open blisters, found that the smooth surface of its sanding into the toad skin, like uneven, then this product is unqualified products, high quality products on the surface of the water should be no significant changes.
Cork floor maintenance
Cork flooring maintenance than other wood flooring is simple, in the course of the use of the day to avoid sand into the room, the individual sand into the belt, it will not affect the wear, so when the sand into the pressure into the foot and pressed into the elastic layer , When the footsteps away, they will be ejected. Of course, here to remind, should not bring too much dirty too much sand, it will produce flow wear, so after the impact into the sand, but too much will wear, so the sand into the room should be promptly removed, do not need to Vacuum cleaner, do not have to worry about moisture will be warped, mildew and so on.
If the use of large traffic occasions, three or five years after the individual if there is wear and tear, you can make up the local use, that is, in the local re-add the coating, the method is very simple, at the wear and tear with sandpaper polished, The surface of the dirt, and then gently wipe with a dry soft cloth, re-coated coating, or in the local coating polyester film.
Geothermal heating floor
Geothermal heating floor, also known as low temperature hot water radiant heating floor, low temperature floor radiation is a use of the building floor heating system. It is the entire floor as a radiator in the floor structure layer of the laying of the pipeline, through the pipeline into the low temperature hot water below 60 ℃ heating floor concrete layer so that the ground temperature is maintained at about 26 ℃, people feel warm and comfortable. Indoor temperature uniform decline, giving the warmth of the head warm the best feeling, in line with the human physiological science.
It saves the room's effective use of the area, and can effectively save energy. The use of low temperature hot water floor heating real temperature than the actual temperature higher than 2 ℃ ~ 4 ℃. It is in line with the "household measurement, sub-room temperature regulation" requirements, no one can stop heating at home, the population can be in the activities of the room heating, turn off the room without room valves.
Long life, the use of aluminum-plastic composite pipe is recognized in the world 50 years of service life of the material. In addition, this heating method also has to reduce the floor noise, clean, wide choice of heat, suitable for the transformation of the old house and so on.
How to choose geothermal flooring
Measuring the true geothermal floor is required by many specific technical parameters. First of all, it must have a good heat dissipation. Geothermal flooring in the selection of materials is very particular about, strictly choose those who meet the requirements of wood density of special substrate. Floor thickness between 6.5-8.5 mm (geothermal floor of the standard thickness), to ensure that the floor has a good ventilation and cooling function. The second characteristic is heat resistance. Geothermal floor of the finished product in fact has a little refined into the taste of steel. In its production process must go through four cycles of rigorous testing. That is: the floor in 100 ℃ hot water for 4 hours → 60 ℃ oven baking 20 hours → 100 ℃ hot water cook for 3 hours → minus 20 ℃ frozen 2 hours. Round trip four times to ensure that the floor long-term high temperature, no cracking, no degumming, anti-moisture, no deformation, not anti-Alice. The last point is green. Health, safety is the fundamental requirements of geothermal floor. Products should comply with international environmental standards (European environmental standards for the E1; Japan's environmental standards for F1; China's formaldehyde release content of less than 0.12mg / m3 equivalent to international standards).
Because the special geothermal floor prices are more expensive, the general wage earners hope to find a cost-effective and meet the requirements of the inexpensive products. Here to introduce several alternatives. There are several wood flooring suitable for floor heating systems: first, 7 to 8 mm thick laminate flooring, with 2 to 3 mm foam cushion; second, 8 to 12 mm thick three or more Layer of solid wood flooring, with 2 to 3 mm foam cushion; third, 8 mm thick stitching parquet or mosaic flooring, with 2 to 3 mm foam cushion; fourth, 10 to 12 mm thick Of the solid wood flat floor; fifth, long, wide and high, respectively, less than 600 × 60 × 15 mm solid wood mouth floor, the best is 200 × 40 × 10 mm specifications of the floor, in the construction of a square or herringbone So that its thermal deformation evenly.
In short, the choice of geothermal heating of the wood floor to master the following principles: the size of the wood floor to be stable, heat stability is better, low moisture content, so that the floor is not easy to deformation after heating; to facilitate heat exchange and conduction, cushion material Too thick; floor size should be thin not thick, should not be wide and narrow, in order to facilitate resistance to deformation, heat conduction requirements.
Plastic floor
Plastic flooring has two kinds of polyvinyl chloride sheet flooring and PVC bulk floor.
Polyvinyl chloride membrane floor is made of polyvinyl chloride resin as the main raw material, adding appropriate additives, in the sheet-like continuous substrate, the coating process produced by the base material with the foamed PVC coil Flooring and the substrate with dense polyvinyl chloride coil floor two, the width of 1800mm, 2000mm, each volume length 20mm, 30mm, the total thickness of 1.5mm, 2mm.
PVC floor flooring suitable for laying the living room, bedroom floor (mid-range decoration), selection should choose excellent products or first-class goods.
The floor area required for the floor can be calculated by multiplying the laying area by 1.10. If the width of the web is exactly the width of the room, you can consider a 2% loss. Coil flooring can be retail, how much to buy the number of inscriptions should be careful planning, to avoid waste.
Polyvinyl chloride block flooring is made of polyvinyl chloride and its copolymer resin as the main raw material, adding filler, plasticizer, stabilizer, coloring agent and other auxiliary materials, by rolling, extrusion or extrusion process, And homogeneous composite two. Its specifications are 300mm × 300mm, thickness 1.5mm.
Each floor area of 0.09, block floor loss rate of 2%.
Coil floor is the wear-resistant layer rolled out on the die for packaging, the application of corrugated box packaging. In each volume of packaging or each box should be marked on the name, production plant name, production date, batch number, grade, color, quantity, weight and so on. In the transport process shall not be affected, sun, rain. Indoor storage of air to flow, dry, from the heat source shall not be less than 1m. The floor of the web should be stacked upright.
Cork flooring
To the cork oak tree bark as raw material through the crushed, hot pressed from a floor. Sometimes, after bleaching and dyeing become color parquet flooring. This kind of floor features; soft feet, good elasticity, strong sealing, and very wear-resistant is a typical silent floor, a great replacement for the trend of the carpet. In China, has a broad development prospects.
Three - layer parquet
From three layers of solid wood staggered laminated, the surface of high-quality hardwood lath trim plywood, the core layer for the cork lumber, the bottom of the peeling board. It overcomes the unidirectional, not easily deformed, and the characteristics of solid wood flooring.
Composite flooring
Composite flooring is generally composed of four layers of composite materials: the bottom layer, the substrate layer, decorative layer and wear-resistant layer. Wherein the number of revolutions of the wear layer determines the life of the composite floor. The bottom layer: made of polyester material, from the moisture effect. Base: generally made by the MDF, depending on the density of different density board, also divided into low density board, MDF and high density board. Decorative layer: is printed with a specific pattern (simulation of the main texture of the main texture) of the special paper into the three ammonia solution after soaking, after chemical treatment, the use of hydrogenated ammonia reaction after the chemical stability, no longer chemical The characteristics of the reaction make this paper a beautiful and durable decorative layer. Wear layer: in the strengthening of the floor surface of the uniform suppression of a layer of aluminum oxide composition of the wear agent. The content of aluminum oxide and the thickness of the film determine the number of revolutions. Per square meter containing aluminum oxide is about 30 grams of wear-resistant layer of about 4000 rpm, the content of 38 grams of the wear speed of about 5000 rpm, the content of 44 grams of wear-resistant revolutions should be 9000 rpm , The greater the content and the film, the higher the number of rotations, the more wear.
Plastic carpet
The main raw material for the polyvinyl chloride resin, additives and other additives made of additives.
Blended carpet
With wool and synthetic fibers, such as nylon, nylon and other mixed woven.
Plastic floor
It is made of polyvinyl chloride plastic as a base material or coil floor. This sheet is flexible, wear, insulation, sound insulation and so on. This floor is more use of extrusion, rolling forming. The adhesive for plastic flooring is a special adhesive.
Multi - layer parquet
To multi-layer plywood as the substrate to the specifications of hardwood foil inlaid puzzle or sliced veneer for the panel, through the urea-formaldehyde resin glue staggered hot pressing, features and three composite floor is basically the same.
Reinforced wood flooring
Reinforced wood flooring from the table AL2O3 wear-resistant layer, decorative layer, the core layer of high density, the bottom layer of moisture from the glue together. Wear-resistant layer with AL2O3 covered in decorative paper, requiring AL2O3 very meticulous, in the process does not cover the decorative layer on the pattern and color, but also evenly attached to the surface of the decorative surface; decorative layer, that is, printing Paper, the surface printed with realistic wood pattern; core layer using high-density fiberboard (HDF), medium density fiberboard (HDF) or high-quality special particleboard. Strengthen the composite floor without paint waxing, easy installation, are new environmentally friendly floor.
Non-woven carpets www.snren.com
The use of non-woven fabric manufacturing technology, that is, raw materials without the traditional spinning process, with the weaving method directly made of fabric.
Chemical fiber carpet
More types, there are nylon, nylon, acrylic, polypropylene, polyester carpet, and so on.
