Formaldehyde emission is a measure of environmental protection wood floor one of the most important criteria. In fact, the wood itself contains aldehyde chemicals, but the content is minimal. Wood flooring in the formaldehyde emission depends on the production of the floor used by the adhesive performance and production process, and the thickness of the floor has nothing to do. In China, usually we are exposed to E-class standards. In the national standard "plywood" (GB / T9846.1-9846.8-2004), the formaldehyde limited level is divided into E0, E1, E2 three levels. Among them, E1 is a mandatory standard, that is, the floor of the formaldehyde emission ㄑ 1.5mg / L, can be used directly in the room without causing health damage to the human body. The E0 is a recommended standard, that is in line with the formaldehyde emission ㄑ 0.5mg / L of the floor, its environmental health is higher.  In Japan, the F-class standards are more stringent, established in 2003, the standard in 10 years to enhance the 7! The most senior F4 star formaldehyde emission ㄑ 0.3mg / L, while the F3 star and the domestic E0-class standard The values are the same.
