Does the paint contain formaldehyde? It is said that the board contains formaldehyde, but do you know that the paint that every household must use for decoration contains formaldehyde?
The source of formaldehyde in home decoration: there must be aldehyde in glue
Formaldehyde is actually a product of unstable decomposition of aldehyde resin adhesives. Because adhesives are widely present in home improvement materials, they have become unavoidable harmful substances. So it can be said that any material with adhesive in the home decoration, whether it has formaldehyde or not, may be a potential releaser of formaldehyde.
Does the paint contain formaldehyde?
A large number of various synthetic resin emulsion interior wall coatings used for interior decoration do not use formaldehyde-containing substances as raw materials in the production process. However, in order to improve the use performance, some coatings may use formaldehyde-containing additives (such as mold inhibitors), but the content is very small. Due to the formaldehyde contained in the raw materials for production of polyvinyl formal, if the reaction is not complete in the production process, the paint will inevitably contain free formaldehyde, which will be emitted during the use of the paint to cause harm to human bodies. Therefore, formaldehyde is also present in coatings.
Decoration materials containing formaldehyde:
醛大户，因为需要胶合木屑，提供强度，这些材料的胶水含量是很惊人的。 1. Traditional particle boards and MDF are traditional large formaldehyde users. Because of the need to glue wood chips to provide strength, the glue content of these materials is amazing. But it is precisely because these materials have matured so much that they have become the focus of special attention that these particle boards now have better regulations and solutions.
As long as you pay attention to the formaldehyde level of the particle board, there is a clear classification of E0, E1, E2, E3 ... In other words, the lower limit of this traditional material is extremely low. Waste products may be infinitely dangerous, but there are already high-quality products that can be clearly monitored and reliable.
2. New artificial boards, such as Hexiang board and OSB board. From the technical development point of view, aldehyde-free grass board is better and safer than traditional particle board. However, as everyone knows, the recognition, understanding, and supervision of new materials are always backward. Many so-called aldehyde-free grass boards, although free of formaldehyde, contain more toxic TDI. And the current high cost of aldehyde-free high-quality products, coupled with high premiums, has led manufacturers to use inferior products to impersonate high-quality products. I'm conservative about this kind of material right now. It should be said that the future is bright, and currently it is more chaotic.
3. Multi-layer solid wood board. In theory, multi-layer solid wood is also a better and safer material than particle board. In theory, it requires less glue than particle board, and its performance is much stronger than particle board. But there is also a problem because it is similar to the Hexiang board, which is good and very poor.
4, wall paint. In fact, the formaldehyde of paint is currently the most transparent among these materials. As long as no fakes are bought, it is customary to divide into several grades, domestic, domestic foreign brands, and imported high-end brands. Personally, I believe that paint should focus on the quality of the paint, not the formaldehyde content, because in fact, the content of harmful substances has not been a weakness of brand wall paints. But the wall paint is the hardest hit area for "formaldehyde hazard" propaganda, and each brand is claiming a brand that is worse than its own toxicity hazard.
5. Reinforced / multi-layer composite wood flooring. If underfloor heating is used, the release of formaldehyde will increase significantly, but it is still controversial whether a higher degree of harm is reached, but the increase in release is certain.
6. Furniture adhesives. After a lot of people renovated, they found that "in fact, the plate cabinets that are very delicious are actually good"; "In fact, the cabinets are very delicious when they come in. In fact, the taste is not good, the walls are painted, and it's fine, No smell at home. " Then the furniture came in and found his nose and eyes narrowed. Because these things are ignored by everyone, leading to a skyrocketing formaldehyde. The release cycle of formaldehyde from this source is also several years.
？ Does the paint contain formaldehyde ? The answer is basically yes, but some coatings contain more formaldehyde, and some coatings contain less formaldehyde. It is recommended that you use environmentally friendly coatings as much as possible, and simple decoration to avoid the damage caused by formaldehyde superposition.
