Data show that the release period of formaldehyde is as long as 3 to 15 years. As a category of carcinogen, indoor formaldehyde is extremely harmful to the body, so it is also known as an invisible killer. In home decoration, formaldehyde is an unavoidable topic, and we often see the health problems caused by excessive formaldehyde. As people's awareness of environmental protection has increased, more and more home furnishing companies have introduced a variety of zero-formaldehyde products, and now the emerging wall decoration material-integrated wall is one of them. Many products say zero formaldehyde, but are there really no formaldehyde at all?
Is there any indoor formaldehyde? Customers can’t distinguish with the human eye when purchasing. It is important to see whether the purchased product has a relative inspection report and Authoritative environmental product certification. According to the "Hygienic Standards for Formaldehyde in Indoor Air" implemented in our country, the maximum allowable concentration of indoor formaldehyde in bedroom gas is expressly stipulated as 0.08 mg/m3.
"Zero formaldehyde" is now undoubtedly synonymous with green, healthy and environmental protection, but in fact "zero formaldehyde" does not mean that there is no formaldehyde at all. The environmental protection standard of formaldehyde is involved here. There are two national standards for indoor formaldehyde content. One is that the national building standard requires a maximum air content of 0.08 mg per cubic meter. The test requires airtight ventilation two hours before the test; the second The decoration standard is that the air content required by the Ministry of Health is a maximum of 0.1 mg per cubic meter, and the test requires indoor air to be closed for more than 12 hours. The second kind is closer to people's usual living conditions, so the second standard is generally used for testing. The currently used formaldehyde limit levels are E2, E1, and E0. E2 is the limit of formaldehyde less than or equal to 5.0 mg per liter, E1 is the limit of formaldehyde is 1.5 mg per liter, and E0 is the limit of formaldehyde is 0.5 mg per liter.
in which E0 is the most stringent environmental protection level,It is equivalent to European E1 and E2 standards. The integrated wall panel has passed the national inspection, and the formaldehyde content standard is 0.2 mg per liter, which exceeds the E0 level specification. Therefore, the term "zero indoor formaldehyde" for integrated wall panels means that the formaldehyde content standard of integrated wall panels exceeds the E0 standard. It is safe and reliable for house decoration and is not likely to cause serious harm to the body.
Therefore, when businesses talk about zero formaldehyde, they often refer to the E0 level formaldehyde emission limit. The product line integrated wall formaldehyde emission limit has reached the E0 level standard. There is no need to worry about the release of formaldehyde and other harmful substances during the installation process. There will be no glue in the installation, thus avoiding the problem of formaldehyde during the installation process, so that the decoration truly meets the standards of health and environmental protection.
The concentration of formaldehyde in decoration exceeds the standard. The reason is that the wall cloth, wallpaper, paint, waterproof material and furniture, wooden floor (especially composite solid wood floor) and other indoor decorations are commonly used in indoor decoration. Formaldehyde content. As a new-style home improvement material, the key to the integrated wall panel is to use aluminum alloy, bamboo fiber, bamboo charcoal fiber, etc. as raw materials. In other words, integrated wall panel itself does not contain indoor formaldehyde, and then At the root, the safe production of goods is guaranteed.
