For the durability of laminate flooring, it is necessary to have 17 physical and chemical properties such as surface abrasion resistance, density, static bending strength and water content.
When consumers buy the floor, they must understand each indicator very clearly. It is difficult to consult the floor experts. If consumers focus on the following three standards, they can take less detours and easily purchase and use the floor. .
Surface wear resistance: The higher the wear resistance level, the less likely the floor is to scratch the surface and the longer the service life. The surface of the laminate flooring is a layer of wear-resistant aluminum oxide, which cannot be repaired once it is destroyed, and the floor is declared scrapped. The quality of the wear layer is not measured by thickness, but is determined by the content and purity of aluminum oxide per square meter. The national standard stipulates that the wear level of the floor used by the family must reach AC3 level (greater than or equal to 6000 rpm), and the use of public places must reach AC4 level (greater than or equal to 9000 rpm). Therefore, when purchasing laminate flooring, do not ignore the wear level of the floor surface due to price factors.
Formaldehyde release limit: National Standard 18580-2001 stipulates that the formaldehyde release limit of laminate flooring must reach E1 level, that is, the formaldehyde emission is less than or equal to 1.5mg/L (dryer method). This is the most basic requirement, and products that meet this standard can be safely used in indoor environments. At present, the international adoption of the higher environmental protection standard E0, that is, the formaldehyde emission is less than or equal to 0.5mg / L. At present, healthy flooring has become the mainstream of consumption.
Installation standard: three-point floor seven-point installation. In the past, there was no clear regulation on the installation of the floor. This year will be the standard year for the wood floor covering market. The national standard "Code for Wood Flooring" GB/T20238-2006 and the Technical Regulations for the Construction of Wooden Flooring by the Ministry of Construction (CECS191:2005) ) has been launched at the same time, will make the wooden floor paving with rules.
