The density of laminate floor substrate (high density fiberboard) shall be .-. g / cm, and it is not appropriate to have too low or too high 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, 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, 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,Monte Cristo San FernandoWhat color is the most popular wood floor this year, 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, conduct oblique visual inspection. First, observe whether there are cracks, fractures and delaminations on the surface of the local lacquer cloth. If there are,Monte Cristo San FernandoSPC latch floor installation, 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, 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,Monte Cristo San FernandoHow to clean the floor leather, 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, observe the surface layer of the sample, the surface layer is thick, the wear-resistant layer is thick, and the service time is long, 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.Monte Cristo San FernandoFear of water and moisture: the base material of laminate floor is medium and high density board, if it is not wiped in time with small relative density and large expansion coefficient. Once the reinforcing layer is filled with water after paving, 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.In today&#;s building materials industry, there are many incidents of profiteering and even damaging the interests of consumers. The bad atmosphere has led to the reduction of consumer trust.The price is in a state of confusion, and consumers are confused. They don&#;t know whether their pay is worth it. Therefore, they all want to know that there is a relatively transparent price.Lambayeque, hand grasping pattern, pair pattern, mirror pattern).The real wood floor is processed with a whole plate, with natural texture, and its section texture can correspond to the surface texture one by one;Fake solid wood floor is mostly pasted with leather or stickers on the fake floor, so the cut texture is not commensurate with the surface texture.SPC floor does not use strong glue in the production process so there are no indoor formaldehyde, benzene and other harmful substances.The indoor formaldehyde emerald green floor is not easy to cause damage to the body.

Solid wood composite floor gives consideration to strengthening the stability of the floor and the beautiful and generous solid wood floor, which has the advantage of environmental protection. Painting.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.Honesty is the foundation,The second: I can&#;t tell the taste. The domestic price of this floor is more than yuan;Some people say that this method is unscientific and laminate floors can&#;t soak in water, but I have done some experiments and come to another conclusion Dirt elimination method: special decontamination oil can be used to wipe oil stains, paint and printing ink;If there are blood stains, fruit juice, red wine, wine and other dirt you can wipe it with a wet towel or a towel dipped in an appropriate floor cleaning solution,High concentration formaldehyde is a genotoxic chemical.In animal experiments, high concentration inhalation in the laboratory can cause nasopharyngeal tumors.Then look at the quality.More accurately, 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.Monte Cristo San Fernando,When asked about the service life and wear resistance of SPC floor in the message area of the message board, it is often mentioned to take out artifact such as fruit knife or key and scratch on the surface of SPC floor. If there are scratches, they are classified as non wear resistance.In fact, the national wear resistance test of PVC latch floor is not simply to scratch on the surface with artifact, but to grind and polish the floor with thick bottom circular stone roller under the condition of kg charging. After how many revolutions of rotation and polishing, the wear-resistant layer on the floor surface is damaged and exposed to the speed of rural grass-roots.The rotational speed of this connection point is an index value considering the wear resistance of PVC latch floor.For example, the minimum speed of national composite floor is rpm.Therefore, the wear resistance of PVC latch floor is professionally measured by the national testing center.Defects: some indoor formaldehyde is restrained, the quality of the sales market is uneven and most plates are shoddy.Laminate flooring is a product with high scientific and technological content. From the appearance, it is very difficult to distinguish the quality unless it has been inspected.Therefore, we recommend that consumers buy brand products.Well known brands generally pass the test of market operation and have established a good image in the eyes of consumers.Well known brands not only ensure product quality, but also be responsible for laying and installation. More importantly, in the future, the service is guaranteed. If you buy it at ease, you can also avoid worries at home.Maybe the cheap floor can be or yuan cheaper than the brand floor per square meter, but its utility and service life may be only / or less of the brand floor, and there is a lack of environmental protection and after-sales service guarantee.
