The most common plastic floor leather on the market today is a polyvinyl chloride coiled floor with a base material (also known as Diocun). It is mainly composed of a base material, an intermediate layer, and a surface wear-resistant layer. There are two types of PVC sheet floorings: foamed PVC sheet flooring with a substrate, code-named FB, and compact polyvinyl chloride sheet flooring with a substrate, code-named CB. When purchasing a specific floor leather, the following items should be considered: (1) Size The width of the coil floor is 1800mm and 2000mm, and the total thickness (referring to the substrate, middle layer, and surface wear layer) is divided into three parts: 1.Smm and Zmm are two sizes;each floor leather is 20m and 30m in length.Other specifications can be determined by both parties of supply and demand.Because of production requirements, each floor leather is divided into several sections (every two paragraphs The pattern is misplaced, so a piece of floor leather with a segment should indicate the length of the short segment, and the length of the roll of floor leather should be increased by at least 20 cm (ie not less than two complete patterns). There is a paragraph, first-class goods and qualified products per roll The number of not more than 2 paragraphs;the length of each section of the first-class product shall not be less than 6m, and the length of the qualified product shall not be less than 4.sin.(2)Appearance quality When the appearance quality of the plastic floor leather is inspected, it shall be under diffuse sunlight or fluorescent light, and the illumination shall be (100 ± 20) lx, distance to the sample to be tested lm, obliquely visual inspection to see. First observe the surface of the floor leather for cracks, fractures and delamination phenomenon, if it can be determined that the floor leather is unqualified. Wrinkle marks, air bubbles, and pattern distortions are present. Unobservable and first grade products are observed. However, slight but inconsiderable quality is recognized as the third step. Whether or not there is a flaw in the surface transparent wear-resistant film layer, none of which are excellent products and first-class products, and those having slight missing printing or lack of film are qualified products, otherwise, they are unqualified products. No deviation, whether there is color difference in different parts, superior product has two or more of the above defects, but there is obvious but not obvious first-class products, obviously there is the above defects, but does not affect the overall appearance is judged as qualified products. Based on the above judgments, the quality of the appearance of floor leather shall be determined.(3) The logo plastic coil floor shall roll the wear-resistant layer outwards on the tube core and shall be packaged outside the package. Manufacturer's name, product marking, grade, batch number, quality, length In addition to the above three items that can be directly sensed, the physical properties should also be taken into account when purchasing floor leather to ensure its service life.
