Use
Formaldehyde is an important organic raw materials, mainly used in the plastics industry (such as system phenolic resin, urea-formaldehyde plastics - jade electric), synthetic fibers (such as synthetic vinylon - PVF), leather industry, medicine, dyes, etc. . Formalin has bactericidal and anti-corrosion ability of biological specimens can be impregnated, the dilute solution (0.1-0.5%) can be used to soaking up agriculture for disinfecting seeds.
In addition to formaldehyde can be directly used for disinfection, sterilization, preservatives mainly used in organic synthesis, synthetic materials, paints, rubber, pesticide and other industries, wood-based panel industry developed, the great demand for formaldehyde.
