Surface wear resistance Use ≥9000 rpm for public places and ≥6000 rpm for households. The above number of revolutions refers to the initial grinding value, that is, the surface of the surface layer is exposed, rather than the wear-resistant final value, that is, the floor is fully worn. The market is that some composite floorings have a high wear resistance, but it is likely to be the final wear value of the target. Water absorption thickness expansion ratio The water absorption thickness expansion rate refers to the degree of increase in the water absorption thickness of the base layer after the composite floor is immersed in water at 25 ° C for a period of time, expressed as a percentage. The greater the expansion ratio, the greater the strength drop of the floor after damp, and the surface protrusions or even falling off, seriously affecting the service life. At present, the size of the water absorption thickness expansion rate of various brands on the market can differ by more than ten times. Surface impact resistance That is, the impact test is performed on the floor in a prescribed manner, and the diameter of the pit left after the impact is the basis of the impact performance. The smaller the diameter, the better the impact resistance and the longer the service life. The wear-resistant layer thickness of the composite floor is above 0.1 mm and the thickness is up to 0.7 mm. Formaldehyde emission According to the provisions of GB18580-2001, the composite floor is a product that can be directly used indoors, so its formaldehyde emission must reach E1 level, ie ≤0.12mg/L. In addition to this, there are indicators such as static bending strength, internal bonding strength, density, moisture content, and bonding strength. The wear level and formaldehyde limit level should be clearly stated when selling. 600*1200mm Marble Porcelain Tiles
