After 2000, the latest technology is one-time pressing of "U" groove, which has the same wear resistance as the surface wear-resistant layer and is easy to clean. "V" is an old technology before 2000, that is, the edge of paint surface has low wear resistance, which is easy to dust and difficult to clean.

In 2009, the national inspection exemption has been completely cancelled.

What I know now are: products that are exempted from inspection for export, selected for the national demonstration project of comfortable living, well-known trademarks in China, and top 500 Chinese brands.

At present, the best substrate is the mate substrate.

Another point is that the latest U-groove technology is the ideal application technology, and V-groove edge coating is out of date.

In terms of environmental protection, the formaldehyde emission of general products is E 1≤ 1.5, and several products are E0≤0.5.

At present, I know very little:

At present, among several major brands, I still think Gloria flooring is better: the export is free of inspection, the product has been selected into the national demonstration project of comfortable housing, China is a well-known trademark, and E0 of the top 500 Chinese brands is ≤ 0.5.

U-groove technology of large submount

The price is cheaper than other big brands.
