меламина 99,8% продуктов питания / промышленное / медицина класса

Physical properties: Melamine is pure white monoclinic crystals, non-flammable, odorless, low toxicity, 1.573g/cm ³ (16 degree), melting point at atmospheric pressure is354 degree. Solubility in water increases as temperature increasing, soluble in water, insoluble in ether, benzene and carbon tetrachloride, soluble in methanol, formaldehyde, acetic acid, glycerol, etc. Chemical properties: Weakly alkaline (PH = 8), and together with hydrochloric acid, sulfuric acid, nitric acid, acetic acid or oxalic acid can make form a melamine salt. In neutral or slightly alkaline environment, all kinds of Methylol melamine could be made by formaldehyde condensation, in the weak acid with hydroxymethyl derivatives generated by polycondensation resin product. mainly use: Melamine is a versatile basic organic chemical intermediate products.It is mainly used as raw materials of the production of melamine formaldehyde.Melamine can also be used as a flame retardant, water reducer, cleaning agent such as formaldehyde resin, the hardness of the high ratio of urea-formaldehyde resin, non-flammable,heat resistance, aging resistance, chemical corrosion resistance arc, good insulation,properties, gloss and mechanical strength, widely used in wood, plastic, paint, paper, textile, leather, electrical, pharmaceutical industries, etc
