Melamine is mainly used for manufacturing melamine formaldehyde resin, which is well water, heat and arc resistant and bright. It can also be used in decorative laminates, Amino plastics, adhesive agents, coatings and used as a paper reinforcing agent, textile auxiliaries, cement water-reducing agent and leather retaining agent.

Melamine is a stable compound with a symmetrical structure. In general the NH2 groups in melamine show an amide character. Melamine is a weak base and can react with various acids to yield melamine salts. Hydrolysis of melamine in strong acids or base solutions results in a stepwise replacement of the amide groups by hydroxyl groups forming ammeline, am elide and cyan uric acid.
Melamine is kind of important organic chemical middle product. It condenses with formaldehyde to product the formaldehyde resin (melamine resin), and owns the advantages of unharmful, heat-resisting, anti-aging, high luster, good insulation and widely used in the fields of plastic processing and wood working is also the chemical of coating, papermaking, textile, paints and leather processing industry.

Cov khoom no yog dab tsi?
Melamine, commonly known as Melamine and Melamine, C3H6N6, is a triazine heterocyclic organic compound, which is used as a chemical raw material. It is white monocline crystal, almost tasteless, slightly soluble in water (3.1g/L room temperature), formaldehyde, acetic acid, hot ethylene glycol, glycerin, pyidine, ether, harmful to the body, can not be used for food processing or food additives.
Daim ntawv thov
In one large-scale application, melamine is combined with formaldehyde and other agents to produce melamine resins. Such resins are characteristically durable thermosetting plastic used in high-pressure decorative laminates such as Formica, melamine dinnerware, laminate flooring, and dry erase boards.
Melamine foam is used as insulation, soundproofing material and in polymeric cleaning products, such as Magic Eraser.
Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.
Melamine also enters the fabrication of melamine polysulfonate, used as a superplasticizer for making high-resistance concrete.
Melamine and its salts are used as fire-retardant additives in paints, plastics, and paper.
