The technology of blockboard is very high, not only requires sufficient space for the wood to have sufficient time for adaptive natural drying, but also strict drying process control through the drying kiln. In addition, the pros and cons of its processing equipment not only requires a large amount of capital investment, but also the key to ensure the accuracy and quality of product processing. In particular, after the country imposes a limit on the amount of hazardous materials for decoration and decoration, the adhesive used for the blockboard must be improved. The cost of this item will increase by about 10%. In addition, the price of raw materials will continue to increase, so it can be said that it is truly green and environmentally friendly. It is impossible to manufacture wood board 50 or 60 yuan. E1 grade large core board conforming to national standards, and about 90 yuan is already meager profit. If consumers are still blindly pursuing the cheap to buy cheap and inferior large core boards that seriously endanger human health, regular production enterprises will be difficult to survive.
Only E1 grade blockboards can be used for home decoration. If the product is E2 grade blockboard, even if it is a qualified product, its formaldehyde content may exceed 3 times that of E1 blockboard, so it should not be used for home decoration. Once again, the blockboard that cannot be finished can be cleaned and sealed, especially the decorated backboard, various cabinet inner panels and heating hoods. Experts have studied formaldehyde sealants, formaldehyde-blocking waxes and elimination and closure. The aerosol of formaldehyde is best used in decoration. However, if the E1 grade large core board is used too much, it may cause the total formaldehyde content in the room to exceed the standard. Therefore, even if it meets the standard, it is not necessarily harmless to the human body.
Generally, no more than 20 pieces of blockboard should be used in the living room of about 100 square meters. At the same time, other indoor decoration should be considered. If used too much, the formaldehyde in the indoor environment will exceed the standard. In particular, do not use a blockboard as a lining under the floor to avoid serious formaldehyde in the indoor air.
