Generally, wear-resistant paper with aluminum oxide content of about g / m is used, or wear-resistant paper is not used.Low density board (medium density board is rarely used), Hubei, Shandong, Liaoning, Jilin and Heilongjiang as the gathering points, not environmental protection, government departments are strictly investigating and dealing with it.Such illegal businesses only take into account short-term interests and have no after-sales service guarantee. The price ranges from to yuan.Then look at the qualityKomoneshti,Fear of water and moisture: the base material of laminate floor is medium and high density board, with small relative density and large expansion coefficient. Once the reinforcing layer is filled with water after paving, if it is not wiped in time, it is easy to cause blistering and deformation due to water absorption and expansion. Its moisture resistance is not strong, and its stability is poor in humid environment.stabilitybolivia, Select the number of wear-resistant revolutionsThe surface texture of solid wood floor is clear and natural, and there is no obvious color difference on both sides.Medium and low grade solid wood floors indicate that cracks may occur.If the crack is not a problem between textures, there will be some hidden dangers if the crack passes through the texture.Laminate flooring has reached grade B and has higher flame retardant performance, which is safer than other kinds of wood flooring
The floor packaging produced by regular manufacturers shall have the manufacturers name, address, instructions and executive standards marked in Chinese.Since , the national standard of laminate flooring has been implemented, and its name and number is the national standard: GB / T - impregnated paper laminated wood flooring. Select the machining accuracy of mechanical equipment. If the address cannot be used temporarily, the indoor air quality and commodity circulation shall be maintained, and it shall not be covered with plastic boxes or newspapers, so as to prevent the long-term surface paint layer from becoming sticky and dull.Manufacturing cost, it must be replaced.As a result the internal cracks will lead to the depression of the wood floor, which has a great impact on the normal use. SPC floor has special anti-skid property. The more it meets water, the more astringent it is. Even if you wear running shoes with nails, you wont leave scratches on the floor.The key injury of formaldehyde is mainly manifested in the stimulation of skin and mucous membrane. Formaldehyde is a toxic chemical substance, which can fuse with protein. When inhaled at high concentration, it has serious irritation and edema of respiratory system eye irritation and headache.
The commonly used floor is generally mm thick, and the .mm wear-resistant layer locks the floor.Such a thick floor generally does not have the situation that the door cannot be closed or affect other s, the material will not be very expensive, the foot feels comfortable, the service life is relatively long, and it will not be easily damaged.Consumers who use wood flooring in home decoration know that if it is not maintained properly in the process of normal use, there will be a series of problems with wood flooring.Floor cracking is a common method.Today, we will discuss why the wood floor cracks.Excellent service,Fourth, high ductility and strong impact resistance.The sports wood floor brings people close to the vitality of nature and can meet modern peoples yearning for green sports life. The wood board is full of vitality, can support people, full of natural flavor and make the moving wood space full of vitality.Waterproof: apply waterproof resin or other waterproof materials at the tongue and groove of the laminate floor, so that the moisture and moisture outside the floor are not easy to invade and the formaldehyde inside is not easy to release, so that the environmental protection and service life of the floor are significantly improved;Especially when laying in a large area, it is inconvenient to leave expansion joints and compression strips,KomoneshtiWood flooring and laminate flooring, it can prevent floor arching and reduce floor contraction joints.Komoneshti The construction of installation works is convenient. 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, wear resistance, pollution resistance, corrosion resistance, heat insulation, sound insulation, moisture resistance, small water absorption, good insulation, self extinguishing, easy cleaning, simple construction, 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,KomoneshtiThe floor leather is strong, 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,KomoneshtiSolid wood multilayer flooring brand, 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 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, 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, 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, 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.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.
