When we buy artificial boards, we should pay attention to whether the formaldehyde emission of the boards meets the requirements. So what is the standard for formaldehyde emission of boards? Next, the editor will briefly introduce it to you.
Nowadays, China's plate and furniture formaldehyde release standard limit is divided into two levels: E2≤5.0mg/L, E1≤1.5mg/L. The more stringent E0 grade (0.5 mg/L) appears as a recommended standard in plywood (GB / T9846.1~9846.8), which is not mandatory.
1. The national standard of "solid wood composite floor" of the People's Republic of China stipulates that the formaldehyde release of grade A solid wood composite floor is less than or equal to 9 mg / 100g, and the formaldehyde release of grade B solid wood composite floor is 9 mg-40 mg / 100g.
2, "National environmental protection label product technical requirements-wood-based panel" provisions: wood-based panel formaldehyde release should be less than 0.20 mg/m3, floor formaldehyde release should be less than 0.12 mg/m3.
3. The European e1 level environmental protection standard is formaldehyde content less than 9mg / 100g, and the e0 environmental protection standard is formaldehyde content less than 3mg / 100g, but according to China's current e0 environmental protection standard, the formaldehyde content is less than 5 mg / 100g. Dee 1 is less than 15 mg / 100 g.
4. European wood products are divided into three grades according to the release of formaldehyde: e1 (formaldehyde content is less than 10 mg / 100 g), e2 (formaldehyde content is less than 30 mg / 100 g), and e3 (formaldehyde content is less than 60mg / 100g).
What we should to pay attention to artificial boards
When we buy artificial plate, we should pay attention to whether the formaldehyde release amount of artificial plate meets the requirements. From October 2021, the new standard will be implemented to divide the formaldehyde release of artificial plate into three levels: E1, E0 and ENF, among which the formaldehyde release of ENF artificial plate is the least, followed by E0 level. When we choose artificial boards, if the economic budget is enough, we can choose a better environmental protection of E0 level and above products. We can ask the merchant to show the quality inspection report when purchasing.
When buying artificial plate, we should check whether the relevant information of the product is complete. For example, we want to check whether the product name, specifications, factory address, contact number, implementation standards, formaldehyde release level and other relevant information is complete. Usually the brand manufacturers of the artificial plate and anti-counterfeiting logo. If we find that the product information logo is blurred, we try not to buy.
In the purchase of artificial plate, we also need to carefully accept the quality of the products. For example, we should check the surface of the plate will not be turned up, touch the plate to give us rough. We observe the side of the plate, whether the connection between the plate layer and the layer is close, whether there is a problem of stratification and so on. You can also use a ruler to measure the thickness of the plate, length and width, check whether the size of the plate is correct and so on.
