It belongs to rubber plastic products. It is one of the indispensable floor materials for the decoration of power distribution room, substation and communication room. The thickness is -mm. Other thicknesses can be made according to the needs of users. The wear-resistant layer is generally less than or equal to .mm.The choice of lacquer cloth products shall be selected according to the suitability of the site.For example, the size of the product is determined according to the space of the house and the size of the place of use.At the same time, and the selected patterns should also be different.For example, in places that need to be kept clean, you can&#;t choose products with convex effect;In solemn places, it is not suitable to choose products with bright colors and messy.The width of coiled floor paint cloth is mm, mm and mm;The total thickness (referring to the base material, intermediate layer and surface wear-resistant layer) is divided into mm and mm;The length of each roll of floor leather is m and m.Other specifications and dimensions can be determined by the supplier and the buyer through negotiation.Because of the requirements of production, each roll of floor paint cloth is divided into several sections (the patterns between each two sections are misplaced), so the length of the small section of a roll of floor paint cloth with sections shall be indicated, and the length of the roll of floor paint cloth shall be increased by at least cm (i.e. not less than two complete patterns).Generally, there can only be one section for high-quality products, and the number of sections of each volume of first-class products and qualified products shall not exceed ;The length of each section of first-class products shall not be less than m, and the length of each section of qualified products shall not be less than m.When inspecting the appearance quality of floor paint cloth leather, it should be visually inspected obliquely under the scattered sunlight or fluorescent lamp with the illuminance of ( ± LX and LM away from the tested sample.First, observe whether there are cracks, fractures and delaminations on the surface of the floor leather.

What cannot be observed are excellent products and first-class products;If it is slight but not obvious, it is deemed as qualified. Go back to the third step to observe whether there are missing patterns on the surface of the floor leather and whether there are defects of the transparent wear-resistant film on the surface. If there is no, it is the first-class product and the first-class product. If there is slight missing or lack of film, it is the qualified product, otherwise it is the unqualified product.Finally, carefully check whether there is deviation during multi-color overprint on the surface, whether there are color differences in different parts, whether the superior products are uneven, the first-class products are those with but not obvious, and the products with obvious above defects but do not affect the overall beauty are determined as qualified products.Finally, based on the above judgment, the appearance quality of ground lacquer cloth is determined.The plastic coil floor paint cloth shall roll the wear-resistant layer outward on the pipe core and shall be externally packaged.The product name, manufacturer name, product mark,DangrigaRequirements of SPC floor on the ground, grade, batch number, quality and length shall be marked at the obvious place of each package.In addition to the above three items that can be directly judged by the senses, attention should also be paid to the physical properties when purchasing floor leather to ensure its service life.The first thing to look at is the tree species.The special use environment of ground temperature is not suitable for all solid wood flooring.
