Is the level of environmental protection in order to make the sheet more solid and durable, wood-based panels need to add moisture-proofing agents and adhesives, which is the main source of free formaldehyde, E1, E0 standard is the European countries according to the content of free formaldehyde in wood-based panels , But also the use of Chinese household man-made sheet standards. E1 grade formaldehyde content ≤ 9mg / 100g, E0 grade formaldehyde content ≤ 3mg / 100g (another calculation standard: E1 level ≤ 1.5mg / L, E0 ≤ 0.5mg / L), therefore, environmental standards and Not the absence of formaldehyde, but the release of formaldehyde to achieve the standard only.
E0 level has not been recognized by the relevant state departments, but an industry standard and does not regulate what is E0 floor? "E0" is a sign of formaldehyde release limits. It refers to the value of less than 0.5 mg per liter of formaldehyde content of the numerical signs (E0 ≤ 0.5mg / l). Last year, the "plywood" national standard GB / T9846.1-9846.8-2004 inside the formaldehyde limit level is divided into three levels, namely E2 ≤ 5.0mg / L, E1 ≤ 1.5mg / L, E0 ≤ 0.5mg / L. "E0 floor" refers to the formaldehyde content of less than 0.5mg / l healthy environment-friendly floor. The reason why it is healthy and environmentally friendly, because 0.5mg / l formaldehyde content is already a very safe numerical standards. According to relevant information, the formaldehyde content of drinking water is 0.9mg / l, that is, E0 floor, formaldehyde content is less than drinking water. However, the concept of healthy environmental protection in the flooring industry has been the knowledge of consumers. As the 2003 by the China Forest Products Industry Association as "quality assured brand", the first to win the "national building materials AAA quality service credit business" honorary title of the world floor that: E0 is not only reflected in a healthy and environmentally friendly way of life, and Or flooring business to consumers a healthy commitment and responsibility, companies should be obliged to assume a good responsibility for consumers to do a good health floor.
Is the national recognition of environmental protection level, a considerable degree of damage to the human body manufacturing
E0, E1, E2 is the formaldehyde emission of three different standards synonyms: E0 ≤ 5 mg / 100 grams E1 ≤ 9 mg / 100 grams (generally said that the environmental protection board indicators) E2 ≤ 30 mg / 100 grams
