Melamine powder with the formula C3H6N6 is an organic compound. This white monocline crystal is a trimer of cyanamide. Melamine is used principally as a starting material for the manufacture of synthetic resins. Its products have excellent heat resistance, flame resistance and good mechanical strength. Melamine is rich in nitrogen, a property that is similar to protein. melamine is almost tasteless, slightly soluble in water (3.1g/L room temperature), soluble in methanol, formaldehyde, acetic acid, thermoethylene glycol, glycerin, pyridine, etc., insoluble in acetone, ether, harmful to the body, can not be used in food processing or food additives.
Modern commercial production of melamine uses urea solution with purity 70% to produce melamine in powder form.
Melamine powder is uses in resins industry, laminate and coating industries, cement & concrete industries, molding Powders, paper Manufacturing industries, adhesives, nitrogen carrier consumer industries, leather, textile, paint & veneer and decoration.
Should be Stored in cool, ventilated warehouse. Keep away from fire and heat. store separately with oxidant, acid, avoid mixed storage.
Manufacture and applications of melamine
Melamine can be manufactured from dicyandiamide, hydrogen cyanide, or urea. Modern commercial production of melamine typically employs urea as a starting material. Urea is broken down to cyanuric acid, which then can be reacted to form melamine. Its most important reaction is that with formaldehyde, forming melamine-formaldehyde resins of high molecular weight. These compounds form under the influence of heat and then become fixed into an insoluble and infusible mold; this process is known as thermosetting. Melamine-based thermoset materials contain cross-linked polymers, which make the fixed molds strong and durable. Usually formulated with fillers and pigments, melamine resins can be molded into dishes, containers, utensils, handles, and the like or used as laminating agents or coating materials for wood, paper, and textiles
It is the main raw material of melamine formaldehyde resin, used as the organic elemental analysis reagent, also used for the synthesis of organic and resin tanning agent of leather processing and filling agent.
Applications of melamine crystal:
Wood industry: to cover a transparent, beautiful and heat-resistant surface on wood
Painting industries: for the production of amine paints (production of car paints, bicycles, etc.)
Paper industry: for the production of transparent, waterproof and anti-wrinkle paper (banknote paper)
Textile industry: providing waterproof, anti-wrinkle fabrics and increasing washability and fire resistance
Leather industry: production of transparent, waterproof and durable leathers
Rubber industry: increasing the adhesion of rubber
Molding: in the form of cellulose fibers in the manufacture of tableware (melamine)
Adhesive: For the production of wood adhesives with waterproof, anti-heat, paint registration and high adhesion properties
Concrete industry: To increase the pumping properties of concrete without the need to increase the amount of water
Fire: Provide fire extinguishing and fire-resistant materials
