Product Detail
Product Introduction
Formaldehyde, chemical formula HCHO or CH ₂ O, formula 30.03, also known as formic aldehyde. Colorless gas with a special pungent odor, which has a stimulating effect on the eyes, nose, and other organs. Gas relative density 1.067 (air=1), liquid density 0.815g/cm ³ (-20 ℃). Melting point -92 ℃, boiling point -19.5 ℃. Easily soluble in water and ethanol. The highest concentration of the aqueous solution is 55%, usually 40%. It is called formaldehyde water, commonly known as Formaldehyde#Forms, and it is a colorless liquid with a pungent smell.
wood industry
Used for producing urea formaldehyde resin and phenolic resin. Formaldehyde and urea are mixed in a certain molar ratio to form urea formaldehyde resin. Phenolic resin is formed by reacting formaldehyde and phenol in a certain molar ratio. The irreplaceable position of formaldehyde in the wood processing industry is being replaced by MDI adhesive.
Textile industry
The use of formaldehyde is involved in the process of resin finishing of clothing. In the production of clothing fabrics, in order to achieve anti wrinkle, anti shrinkage, flame retardant and other functions, or to maintain the durability of printing and dyeing, or to improve the feel, formaldehyde needs to be added to the additives.
Anti-corrosion solution
Formaldehyde is a substance released from the decomposition of formaldehyde Sodium bisulfite above 60 ℃. It is colorless, has a pungent smell and is easily soluble in water. 35%~40% formaldehyde aqueous solution, commonly known as Formaldehyde#Forms, has antiseptic and bactericidal properties and can be used to soak biological specimens, sterilize seeds, etc. However, due to protein denaturation, the specimens are easy to become brittle.

Urea formaldehyde resin adhesive
Urea formaldehyde resin, also known as urea formaldehyde resin. The abbreviation UF refers to the condensation of urea and formaldehyde in the presence of a catalyst (alkaline or acidic) to form an initial urea formaldehyde resin, which is then treated with a curing agent or auxiliary agent to form an insoluble and non melting final thermosetting resin.
