1. preservative solution paraformaldehyde is a colorless, decomposed product of formaldehyde Sodium Bisulfite at 60 degree Celsius. It has an odor and water soluble substance. The formaldehyde solution of 35% to 40% is commonly known as Faure Marin's solution. It has excellent functions of antisepsis and sterilization, and can be used to soak biological specimens.
2. the wood industry is used to produce urea formaldehyde resin and phenolic resin, and the urea formaldehyde resin is reacted by the mixture of paraformaldehyde and urea at a constant molar ratio. Phenol formaldehyde resin was synthesized by mixing formaldehyde and phenol at a constant molar ratio.
3. the production of textile fabric is due to the effect of wrinkling, shrinkage, flame retardancy, or in order to adhere to the durability of printing dyeing, it is necessary to add formaldehyde to the additives.
