We can also scrape the board with a blade.The real solid wood floor is painted with wood, and the refurbished board is made of floor, white putty and paint.Scrape the surface with a blade. If it is white, composite and reinforced?More accurately, SPC floors with obvious pungent smell should not be environmentally friendly.SPC rural grass-roots raw materials themselves do not contain indoor formaldehyde. The qualified SPC floor should be . There is no formaldehyde release. It is likely to have the taste of air fragrance and modifier. It is not easy to cause harm to everyone&#;s body and make people feel uncomfortable.Although the installation method of SPC latch floor is the same as that of wood floor, the grasp of details in the installation process is also different from that of wood floor.According to the current market survey, the SPC lock floor of different brands will have edge warping, arching, large expansion joints, and even lock fracture after paving on individual sites.Monsanto,Second, mild to moderate scratches. Good wear resistance and stabilityKisa,When choosing wood flooring in , customers attach great importance to quality.Although the solid wood floor is good, the maintenance is very complicated.In , all stores released high wear-resistant solid wood flooring.It is said that this kind of floor not only has the characteristics of high wear resistance and general solid wood floor, but also has strong coating adhesion,MonsantoComposite laminate manufacturer, high definition, good corrosion resistance, strong waterproof not easy to crack and paint.High concentration formaldehyde is a genotoxic chemical.In animal experiments, high concentration inhalation in the laboratory can cause nasopharyngeal tumors. Scrape the board with a blade.

Establish the interior decoration style you want: if you expect simplicity and warmth, choose the sexual or shallow floor as much as possible, and if you expect calm air, choose the dark floor.The color is gorgeous, the texture is clear, and the pattern gives people a beautiful feeling.It not only has axial drilling texture but also has irregular thick and light parallel lines for wood texture, with clear and smooth texture and a sense of hierarchy;There are also rotary drilling textures. The wood texture also has mountain or wavy lines. The texture is beautiful, Sticker method: stick the same wood grain paper on the front and back of the board. In terms of foot feeling, solid wood is better than reinforcement. According to national industry standards, all solid wood is mm thick, and wood keel ceiling is selected for installation, so the upper foot is better than mm thick reinforcement plate.How to distinguish true and false solid wood flooring?Fifth, the total thickness of the floor is about , cm, which is also related to his total price.

The cross section of the floor is rubbed with a file, so that the heat generated in the cross section is the full volatilization of formaldehyde (formaldehyde will accelerate the release above ℃, and some irritating smell can be smelled). At this time, you can smell it. Generally you can smell three different levels of smell:Pursuit of excellence, 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,MonsantoWhich is a good SPC floor, and stratification will soon occur in future use.Plastic floor paint cloth has the advantages of light weight, good mechanical strength, good foot feeling strength, comfortable foot feeling, wear resistance, 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, high and medium grade products should be selected, 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, generally thin thickness and large shrinkage coefficient. When checking the appearance quality of rubber plastic floor paint cloth, it should be under scattered sunlight or fluorescent lamp and the illumination should be ( ± LX, LM from the tested sample, 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, 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, pattern and thickness. When purchasing, carefully observe the appearance quality, open a roll of ground lacquer cloth, separate the ends for a few meters, the wear-resistant 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, missing, lack of film and overprint deviationDefects such as color difference, color difference and pollution.The relative density of laminate floor board (plywood with high density) should be .-.g/cm, which is not suitable for too low or too high. days later, maggots grow on the floor. This problem occurs because the floor contains a lot of impurities.Monsanto,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, 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, it is Class B flame retardant grade.Instead of watching it burn.Common types: three-layer solid wood composite floor, double-layer solid wood composite floor, new solid wood composite board. Keep the floor dry and clean. If there is dirt on the floor surface, generally wipe it dry with a damp mop without dripping water.
