As a professional office furniture practitioner for 18 years, Guangzhou Lijiang Chair Industry Co., Ltd. today talks about the formaldehyde problem in furniture or office furniture. First of all, we need to understand the source of "formaldehyde". Formaldehyde is a colorless gas with a strong pungent odor, which mainly appears in the form of aqueous solution. It is known as formalin. It is mixed with urea to form urea formaldehyde resin, which is widely used in various adhesives. Because of its low price, it is basically in the wood market in China. In the world, MDI (polyurethane) or isocyanate is used to replace formaldehyde in wood processing. At present, the main raw materials of domestic office furniture industry are plastic plywood and metal. Needless to say, metal plywood is what we often call particleboard and fiberboard. It is made of plant fiber as raw material, adding adhesive and hot pressing. The utility model has the advantages of low cost, easy processing, no straight deformation, etc.
If in order to reduce formaldehyde and reduce the total amount of adhesive, the strength of the board itself will decline. If other types of adhesives are selected, the cost will rise. There are standards for formaldehyde emission of boards. The domestic standards are divided into E1 and E2. The E1 of drying oven method is less than or equal to 1.5mg/l, and E2 is less than or equal to 5.0mg/l. E1 boards can be directly used for interior decoration, and E2 boards must be used for interior decoration after treatment. Therefore, if you want to choose environment-friendly office furniture, you should choose metal or solid wood based office furniture whose board reaches E1 standard.
