Plywood is the most common type of plywood, which is made by sticking three layers of thin wood in different grain directions. The plywood was invented in 1810, and British scientists used plywood to make light aircraft, which was then widely used in industry. China began using plywood in 1910, mainly for watch boxes and crafts, mostly three stories.
Although plywood is widely used, its harm cannot be ignored. Since the binder containing formaldehyde is used in the production, the use of the plywood for furniture releases formaldehyde. Formaldehyde can cause diseases of the respiratory tract and nervous system, such as cough, sore throat, chest tightness, dizziness, nausea, weakness of the limbs, difficulty breathing, lethargy, etc., but also induce cancers such as nasal cancer, throat cancer, skin cancer and leukemia. occur. Generally, the release time of toxic gases is 1-10 years, especially in the first year. During this period, the toxic gases evaporate quickly and the release amount is high, which is harmful to the human body.
Since harmful gases such as formaldehyde in the room can damage the health of the human body, it is best not to buy furniture made of synthetic sheets, especially for families with children. If you already have sheet furniture at home and feel that the smell is particularly strong, it is best to have a qualified monitoring agency to monitor whether the indoor air environment is up to standard. In addition, photocatalytic products can be used to reduce the harm caused by harmful gases.
