Molecular Structure:

Product description: Melamine(Micronized) Molecular structure of chemical: Molecular Formula:C3H6N6 CAS:108-78-1 EINECS No. 203-615-4 Appearance: White powder Melamine contain > 99.8% Density 1.573g/cm3 Solubility In water <0.4g/100ml(20℃) Water ≤0.1% Ash ≤0.03% Melting point 354℃ PH 7.5-9.5 Particle size: 40um max Packing: 25kg/per bag 20”FCL: 20000kg(pallet) Physical Properties: Properties of pure white melamine edge monoclinic crystal, non-flammable, odorless, low toxicity, non- dangerous chemical. density 1.573g/cm3 (16 ℃). Pressure melting point 354 ℃, the rapid heating the decomposition; rapid increase sublimation, sublimation temperature 300 ℃. Solubility in water increases with temperature, at 20 ℃, about 3.3 g / L, that is slightly soluble in cold, soluble in water, very slightly soluble in hot alcohol, insoluble in ether, benzene and tetrachloride carbon can be dissolved in methanol, formaldehyde, acetic acid, hot ethylene glycol, glycerol, pyridine and so on. Chemical properties Weakly alkaline (pH value = 8), and hydrochloric acid, sulfuric acid, nitric acid, acetic acid, oxalic acid can form a melamine salt. In the case of neutral or slightly alkaline, with a variety of formaldehyde condensation formed hydroxymethyl melamine, but in the slightly acidic (pH value of 5.5 ~ 6.5) and hydroxymethyl derivatives generated by polycondensation resin product. Case of aqueous solution of strong acid or alkali hydrolysis, hydroxyl amine and gradually been replaced by President into cyanuric acid amide II, and further hydrolyzed cyanuric an amide, and finally generate cyanuric acid. Uses: 1) Decorative Panel: can be made of flame retardant, earthquake, heat-resistant laminate, bright color, strong heat-resistant decorative panels for aircraft, ships and furniture, plywood and fire, earthquake, heat housing decoration materials. (2) Paint: Use alcohol, alcohol ether of a post as senior thermosetting coating, powder coating of solid plastic joint agent, can be made of metal coatings, and vehicles, electrical appliances with high-grade amino resin decorative paint. (3) Molding powder: After mixing, granulation processes can be made of melamine plastic, excessive, dirt, moisture was still good electrical properties, can be made into white, impact play of the household utensils, health ware and melamine tableware, electrical appliances and other high insulation. (4) Paper: After the ether with ether can be used as paper processing agent, producing anti-wrinkle, anti-shrinkage, non-perishable money and military maps and other senior paper. (5) Melamine - formaldehyde resin mixed with other materials can also produce fabric finishing agents, leather tanning Run agents, polishing agents and anti-agent, rubber adhesive, accelerant, efficient cement water reducer, steel dilute agent.
