Formaldehyde is a colorless, irritant and water-soluble gas

formaldehyde is a colorless, irritant and water-soluble gas. It has the function of coagulating protein, and its 35% - 40% aqueous solution is generally called formalin, which is often used as the solution for impregnating samples

formaldehyde is a highly toxic substance, ranking second in the list of priority control of toxic chemicals in China. Generally, the formaldehyde content of newly decorated houses can reach 0.40mg/m3, and some may reach 1.50mg/m3

environmental friendly materials are not pollution-free. If the formaldehyde content in 100g wood-based panel is less than 9 mg, it can be called environmental friendly materials, but the problem is that in our decoration, it is impossible to decorate a large room with a piece of wood-based panel

if the formaldehyde emission per 100 grams is 8 mg, the formaldehyde content of a 30 kg board is 2400 mg. If 40 such boards are used for decoration, the formaldehyde content is as high as 96000 mg. Therefore, environmental protection materials are used more, and the room space is limited, pollutants will be accumulated and released into the air

many of the contracts of decoration companies promise that "if environmental protection materials are used in the decoration process, ten will be fined for each fake", which makes many citizens mistakenly believe that the air quality is also qualified

there are E1 and E2 grades in artificial plates. E1 grade board is environmental friendly and green, and the formaldehyde emission per 100 grams is less than or equal to 9 mg. And E2 grade board, the formaldehyde emission per 100 grams is less than or equal to 30 mg, which is the standard board stipulated by the state, and cannot be directly used for indoor decoration. If the E2 level is not reached, it is an unqualified plate

you need to look at the formaldehyde emission marked on the board

in general, the longer the house is used, the less formaldehyde remains in the indoor environment; The higher the temperature, the greater the humidity, the more conducive to the release of formaldehyde; The better the ventilation conditions are, the faster the formaldehyde in buildings and decoration materials is released, which is more conducive to the cleaning of the indoor environment
