Anonymous users2024-01-24The methanol value of China's environmental protection standard is less than or equal to 40mg of formaldehyde per 100g.
The European minimum standard is E-1. What is E-1, that is, the amount of formaldehyde per 100g is less than or equal to 10mg. Particleboard, MDF, plywood and various wood-based panels all use a large number of adhesives, and the adhesives mostly use formaldehyde as the solvent raw material.
Furniture made of panels with high formaldehyde content will continuously release toxic formaldehyde gas, which will cause long-term irritation to the eyes and respiratory system of users, resulting in a decline in the function of the lungs, liver and immune system, which seriously endangers health and life safety. The standard E-1 board is 100% imported from Europe, from the material to the production process are subject to the strictest control, the product is regularly sampled and tested by the EU accredited testing center, and its formaldehyde emission is 6-8 mg 100 grams, which is lower than the international E-1 standard of 10 mg 100 grams.
E0 grade board is less than or equal to 3mg of formaldehyde content per 100g, which is the best board on the market now.
Super E0 grade is no formaldehyde.
What is the difference between E1 and E0 in terms of cost? It can be said that the cost of E0 is 2-3 percent higher than that of E1, so some manufacturers may mainly promote E1.
Limited Value.

The national standards for formaldehyde content of wood products are: E1 less than 10mg 100g, E2 less than 10-30mg 10g, E3 less than 30-60mg 100g; China's GB T14732-93 national standard stipulates that the release of free formaldehyde is less than 40mg 100g. >>>More
The highest level of the national standard is E1 grade formaldehyde emission directly used in indoor home decoration. Japan's formaldehyde emission standard is the highest in developed countries, Japan's F4 star standard formaldehyde emission volume, although our country's standard is much lower than Japan's, but we have always had excellent enterprises in the research and development of new materials, and there has been a great breakthrough in formaldehyde release. Some time ago, the media reported that Yongen Zero Formaldehyde Company, a company that does environmental protection building materials, joined hands with ICBC, CCB, Haier and other top 500 enterprises to launch the "Youth and Children's Housing Public Welfare Testing" activity in the country, in order to advocate the new standard of zero formaldehyde, this company can release formaldehyde, which far exceeds the highest standards of developed countries, and it seems that China's standards still have a great chance to lead in the world.
Estimated contained? More ventilation and conditions to increase the indoor temperature, so as to speed up the volatilization of formaldehyde.
There is no specific index for the formaldehyde content of solid wood furniture to be much lower than that of panel furniture, and it is generally much lower. >>>More
