порошок меламина

Physical properties:White crystalline powder, innoxious, flavorless.Chemical properties:Melamine presents alkalescence, can react with various acidums to generate melamine salt. In strong acid or strong alkali liquor, melamine will hydrolyze---amido group will be slowly replaced by hydroxyl, thus generate ammeline, Cyanuric Acid and Ammelide. It can react with aldehydes to produce addition compounds. Among them, the reaction of melamine and formalin is the most important part.The application state of melamine : Melamine is a semi-finished product in organic chemical industry with even structure and vast applications; it is mainly used as the material to produce melamine formaldehyde (MF) colophony. Owning the abilities of fire-resistant, water-resistant, hot-resistant, age-preventing, electric arc resistant, bearing chemical corruption, perfect insulation capability, gloss grade, and machinery intention, and good thermal-setting capacity, it is widely used in wood, plastic, dope, paper-making, textile industry, leather, electric, and medicine, etc.GradePremium gradesContent(%), min99.8Moisture(%), max0.1Ash content(%), max0.03Color (Pt-Co) degree, max20Kaolin turbidity degree, max20PH7.5-9.5AppearanceWhite powderMolecular formulaC3N6H6Density700-900kg/ m³Melting point (oC)354
