you can tear it by hand. If it can be easily torn off

Test: for the ground lacquer cloth with thin thickness, 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, elasticity, 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, 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, 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, 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, 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, pattern and thickness. When purchasing,Republic of Bosnia and MontenegroWaterproof board, 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, the wear-resistant layer is thick, and the service time is long, and then observe whether there are cracks, 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, destroy the characteristics of various wet expansion and contraction, and the specification is very stable, especially for rooms with heating system.Republic of Bosnia and Montenegro, After the primer is dry, brush the first finishing coat and dry it. Fire protection: the fire rating of SPC floor is B, second only to stone. It will automatically extinguish after leaving the flame for seconds, flame retardant non spontaneous combustion, and will not produce toxic and harmful gases.It is suitable for occasions with high fire protection requirements.General town of Roca, Fire protection, fire rating B, second only to stoneColor film layer: various decorative layers of wood grain, stone grain and carpet grain, which can meet the different needs of different occasions and different tastes.Laminate flooring is suitable for meeting rooms, offices, high-definition cleanliness laboratories, etc. it can also be used for the ground decoration of medium and high-grade hotels, restaurants and civil houses.Although laminate floor has moisture-proof layer, it should not be used in wet places such as bathroom and toilet.The first is the type of raw material.When purchasing solid wood multi-layer wood floor, you should pay attention to whether the floor is the same material and whether the surface has defects such as crack, rot, skin clip, dead joint, moth eaten, moldy and so on.The general high-quality solid wood multi-layer wood floor shall have clear lines and bright colors on the surface.

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 an elegant feeling. If you want to use them for short-term use or one-time cover,Republic of Bosnia and MontenegroShengda laminate flooring, you can choose low-grade products, because the price of low-grade products is low, 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. Laminate flooring is generally composed of four layers of composite materials, namely wear-resistant layer, decorative layer, high-density substrate layer and balance (moisture proof)Laminate floor is also called impregnated paper laminated wood floor and laminate floor. Qualified laminate floor is made of one or more layers of special impregnated thermosetting amino resin. Exposure to obvious sunlight, or significant increase or decrease in room temperature, will cause early embrittlement of solid wood board floor paint, which should be minimized.
