The standard specifications are adopted by most members of the European flooring Producers Association. This is still the case. China also adopts the standard specifications when importing the most advanced laminate processing lines in the world. In other words the products of large laminate manufacturers processed by imported lines are still the standard specifications. There are many dealers in the market who flaunt themselvesOur products are imported. It is often said that 'imported ones have no wide plate specification and thickness of about mm'. It should be that most imported floors have no wide plate specification and thickened size.The joint of the floor adopts the form of latch, which controls the vertical displacement of the floor and the horizontal displacement of the floor;The original tenon and groove type, which is often called tongue and groove floor, can only control the vertical displacement of the floor.No matter how early the wooden floor plate is, there is no tenon and groove at the joint, and the displacement in any aspect can not be controlled. Therefore, the floor plate often tilts up and stumbles when walking, which is inconvenient.Traun,Second, mild to moderate scratches.Generally, the thickness of composite floor is about cm. From the height of the building,TraunWood floor color change, I don&#;t think this is its advantage!what?After all, the gap of cm is very small.Kosong, Select substrate density Test: for the ground lacquer cloth with thin thickness you can tear it by hand. If it can be easily torn off, the tear strength of such ground lacquer cloth can not meet the requirements. After gently rolling up and pressing down, if it can not be restored to the original state and leave an indentation, such a product has poor softness.If the layers can be torn by hand, it indicates that the product layers are not well combined, and stratification will soon occur in future use.Plastic floor paint cloth has the advantages of light weight, elasticity, good mechanical strength, good foot feeling strength, comfortable foot feeling, pollution resistance, corrosion resistance, heat insulation, sound insulation, moisture resistance, small water absorption, good insulation, self extinguishing, easy cleaning, simple construction, convenient maintenance and low price. In a large number of civil buildings and public places, it has high requirements for cleanlinessIt is widely used in the laboratory.Plastic floor paint cloth belongs to soft floor. It is a floor coil produced by coating or calendering on sheet continuous substrate with polyvinyl chloride resin as the main raw material and appropriate additives.The length of each roll of plastic floor paint cloth is m ~ m, the width is mm ~ mm ~ mm, and the total thickness is mm (machine room) ~ mm (plant and public buildings)For long-term indoor use, and products produced by well-known brands and regular enterprises should be purchased as far as possible. Such products have sufficient thickness and good interlayer adhesion, and are not easy to layer and curl especially foamed leather, which gives people a comfortable and elegant feeling. If you want to use them for a short time or one-time cover, you can choose low-grade products, because low-grade productsThe price is low and there are many prices to choose from, but many of these products are processed with waste materials, with poor flexibility, it should be under scattered sunlight or fluorescent lamp, LM from the tested sample, conduct oblique visual inspection. First, observe whether there are cracks, fractures and delaminations on the surface of the local lacquer cloth. If there are, it can be judged that the local lacquer cloth is unqualified. The second step is to observe whether there are wrinkle marks, bubble pollution points and pattern deformation. Those that cannot be observed are excellent products and first-class products; those that are slight but not obvious are recognized as qualified. Go back to the third step for observationIf there is any missing pattern on the surface of the ground lacquer cloth, or if there is any defect of the transparent wear-resistant film on the surface, it is the first-class product and the first-class product. If there is a slight missing print or lack of film, it is the qualified product, otherwise it is the unqualified product. Finally, carefully check whether there is deviation in the multi-color overprint on the surface, whether there is color difference in different parts, if the top-class product is uneven, if there are the above two defects, but if there is no obvious, it is the first-class productProducts that obviously have the above defects but do not affect the overall beauty are judged as qualified products. Finally, the appearance quality of ground lacquer cloth is determined based on the above judgment. When selecting ground lacquer cloth, first smell whether it has pungent smell. There will be a slight smell after the good coil is opened, and the smell of inferior products is stronger; secondly, calculate the use area, and the same room should be selectedCoiled materials with the same batch number,TraunWhen will the floor be installed better, pattern and thickness. When purchasing, carefully observe the appearance quality, open a roll of ground lacquer cloth, separate the ends for a few meters, observe the surface layer of the sample, the surface layer is thick, and the service time is long, and then observe whether there are cracks, fractures, wrinkles, bubbles and large defects; whether the cross section is layered and cracked; whether the pattern is open, lack of film and overprint deviationDefects such as color difference, color difference and pollution.The standard ones are generally -mm wide, about and long. The wide ones are mostly more than mm long and about mm wide. The narrow ones are - mm long and about mm wide. They are similar to the specifications of solid wood flooring, and most of them are called imitation solid wood flooring.

In addition, pay attention to whether there are sawdust and stratification on the cutting surface of the plate and whether there are sawdust and stratification on the cutting surface of the solid wood floor.During the test of solid wood floor in the factory, if some wood floors are found to be warped or falling off, the wood floor shall be taken out immediately, the old glue or ash chips shall be removed, glued and tamped.The water resistance is reflected by the water absorption thickness expansion index. If the index value is high, the water resistance is poor, that is, it is easy to cause size change in humid environment.Must not listen to the misleading such as waterproof floor, only moisture-proof floor, no waterproof wooden floor.Installation works,Look at the substrate, break the floor and look at the substrate inside. There are no impurities in the good substrate and the color is relatively pure. A large number of impurities can be seen with the naked eye in the poor floor substrate.Most domestic floors use fast-growing forests, and wood has been used since to years. However, imported floors, especially FSC certified plates, have strict restrictions on wood species, so wood base materials are better.Second, the time of birth.The third is color.Some customers are very strict about the color of the floor and must maintain the same color difference.But this provision is unscientific.Because the wood is affected by the sun raw material parts, growth and development parts and lower sawing points, it will inevitably cause inconsistent color difference.

Some customers want to take a lighter to light the SPC floor to see if it can burn. If it burns, it is not fire safety, and if it doesn&#;t burn, it is flame retardant.In fact, the national regulations on the flame retardant grade of PVC latch floor meet the B Standard and the flame retardant raw materials are listed as class a fire safety according to the national standard, such as marble, wall tiles, etc.The technology of Class B flame retardant grade includes mm diameter cotton wool,TraunLaying method of floor leather, sprinkled with ethanol, and placed on the PVC latch floor for natural ignition. After the cotton wool is burned, accurately measure the diameter of the burned PVC latch floor impression. If it is less than mm,Men&#;s long-term inhalation will cause men&#;s abnormal sperm and death.First the scope of application is small.Finally, look at the price.Small blisters can not be repaired after damage, and the upper foot is weak.Traun, SPC floor adopts marble powder and new materials, which is more green and environment-friendly.The cost of stone plastic floor is quite low and it can be flame retardant. It has no affinity with water and is not easy to mildew. Stone plastic floor has sound-absorbing effect, so we don&#;t have to worry about the sound of high-heeled shoes hitting the ground anymore. The packaging is rough, the printing quality of the publicity album is poor, the attributes are pieced together, and the slogan selling points are set by set, which often misappropriates the album attributes of large companies.How to buy solid wood composite flooring?
