[Chinese wardrobe network] [background] Xiaohong (referred to as "Hong Yang home delivery") found that many owners when buying furniture, always listen to the seller that they are using E0 or E1 grade plates, but specific to them Representing the environmental standards, our owners are all confused. Therefore, Xiaohong deliberately summarized this content and hoped to help everyone. [Consumption problem] What is e0, e1, e2 grade sheet? [professional answer] 1. What is the E0, E1, E2 sheet? E0, E1, and E2 all refer to environmental standards for formaldehyde release limit levels. The first two standards, E1 and E2, were produced in Germany and were developed by EGGER and later cited as European standards. E0 was officially appeared in the "Plywood" national standard (GB/T9846.1-9846.8-2004) promulgated in 2004, mainly based on the Japanese environmental protection standard F3 star. At present, only the countries in Finland, Japan, Germany and other countries enforce the E0 standard, and China implements the recommended standard. E0 ≤ 0.5mg / L is a very safe numerical standard, formaldehyde content is less than drinking water (ie 0.9mg / L); and E1 ≤ 1.5mg / L is "can be treated, completely harmless to humans and animals". However, at present, the basis for the safety of family living environment in China is mainly the National Standard for Indoor Air Quality (GB/T18883-2002), which stipulates that the formaldehyde concentration should be 0.10mg/m3, which is the total amount of indoor formaldehyde emission control. Exceeding odor and discomfort may occur. 2, formaldehyde source and harm According to a survey conducted by the China CDC in 2005, the formaldehyde over-standard rate of residential decoration in China is as high as 60%. The hidden dangers of formaldehyde exceeding the standard are extremely worrying, especially the artificial board is the main cause of formaldehyde pollution in indoor air. The wood-based panel is made of urea-formaldehyde resin as a binder. Urea-formaldehyde resins are direct compounds of formaldehyde and urea. For every 3 square meters of wood-based panels, about 1 kg of formaldehyde is used to synthesize the urea-formaldehyde resin required for the board. Announcement No. 153 issued by the World Health Organization in 2004 pointed out that formaldehyde is carcinogenic. Mild, severe inhalation can cause the following diseases: 3â„4 chronic respiratory diseases, allergies 3â„4 nasopharyngeal carcinoma, colon cancer, brain tumor, uremia 3â„4 infertility, miscarriage, fetal malformation or stillbirth 3â„4 neonatal immune system developmental disorders, mental retardation, congenital asthma 3â„4 pediatric leukemia 3, Hong Yang home with the recommended use of Wanhua ecological board Wanhua Ecological Board has been certified as a non-aldehyde-free plate by the national inspection report. It has won the US CARB aldehyde-free exemption certification. Its aldehyde-free quality has been tested and certified by the world's three major national authorities and is the world's safest new environmentally friendly sheet. Wanhua Ecological Board advocates “making furniture as safe as fruitâ€. The whole house of the Hongyang home is equipped with Wanhua ecological sheet as the substrate. The MDI glue with the national protection grade patent eliminates the harm caused by the long-term cumulative release of formaldehyde from the source, and truly gives consumers a Easy to use home!
