E0 grade sheet is more environmentally friendly than E1 grade. Environmental protection sheet is divided into E grade according to formaldehyde emission content. E0 grade sheet formaldehyde emission ≤0.5mg/L, E1 grade formaldehyde emission 0.5mg -1.5mg/L, the less formaldehyde emission, the better the board, the more environmentally friendly, E0 board is currently the highest environmental protection level board on the market.
Board grade classification (Formaldehyde emission ≤0.5mg/L), E1 (formaldehyde emission 0.5mg-1.5mg/L), E2 (formaldehyde emission greater than 1.5mg/L) .
E0 level is a big improvement compared to E1 level. After all, the formaldehyde content of our tap water reaches 0.9mg/L. It is considered qualified, which means that the formaldehyde content of E0 level board is actually higher than the tap water we drink. The content is low. However, although the E0 board is the highest environmental protection level among the ecological board levels. But it still contains a certain amount of formaldehyde, which is not completely harmless, because this formaldehyde emission is only certified, that is, the formaldehyde emission of 1L is below 0.5mg. When we use it for interior decoration, we will use a lot of panels. When many boards release formaldehyde together, even if they use E0-level boards, it cannot guarantee that the indoor air formaldehyde content is up to the standard. Don't believe that the E0-level boards used by merchants to promote their products are absolutely safe and healthy.
E1 board is a board that can be used for interior decoration according to national regulations.This kind of board can smell a slight pungent smell. However, many brands of E1 boards have only passed the certification, but the production technology is very outdated. In fact, the random-checked products are not qualified at all, far less than the E1 level. However, consumers are not insiders, and there is no way to tell them apart. This is why the product description provided by the board furniture merchants we bought uses E1 grade environmental protection board, but it still has a great pungent smell. Therefore, even if the home decoration is made of E1 grade environmental protection panels, it needs to be ventilated for a period of time. After the smell is gone, check in again. Checking in too early will damage your health.
E2 grade sheet has a strong pungent smell, it is not allowed to be used directly for interior decoration, and it must be used after finishing treatment. The finishing process is uneven, and it is difficult to ensure that the formaldehyde emission of the board after treatment can reach a healthy standard. In addition, since there is no upper limit for the formaldehyde content of E2 grade panels, if you see that the product uses E2 grade panels, basically do not consider indoor use. Long-term living in an environment with pungent smell of formaldehyde can induce many human diseases, among which cases of leukemia induced by formaldehyde problems are not uncommon.
Formaldehyde can be seen everywhere in our lives and it is unavoidable. The air we breathe, the wood raw materials, the water we drink, and all kinds of beverages all contain a certain amount of formaldehyde, but these natural materials formaldehyde The content is not enough to cause harm to human health. This is why pure solid wood furniture is very popular, and wood-based panels cannot avoid the use of glue when manufacturing. 99% of panels on the market today need to use urea-formaldehyde glue containing formaldehyde to produce, and we want to produce panels with high environmental protection levels. , Can only rely on reducing the amount of glue used and sealing on the surface of the board to control the release of formaldehyde. When we are decorating, not only the board will release formaldehyde in the room, but also the putty and textile of the wall contacting the board will also contain formaldehyde, which will affect the overall formaldehyde emission of the board.
