Melamine

Specification: 25kg；500kg；1000kg

Product form: white, monoclinic crystal

Product standard: GB / T9567-1997

Performance:

It is nonflammable and stable at room temperature. The aqueous solution is weakly alkaline (pH = 8) and can form melamine salt with hydrochloric acid, sulfuric acid, nitric acid, acetic acid and oxalic acid. In neutral or slightly alkaline conditions, it condenses with formaldehyde to form various hydroxymethyl melamine, but in slightly acidic conditions (pH 5.5 ~ 6.5), it condenses with hydroxymethyl derivatives to form resin products. In case of hydrolysis of strong acid or strong alkali aqueous solution, the amine group is gradually replaced by hydroxyl group to form cyanuric acid diamide, further hydrolyze to form cyanuric acid monoamide, and finally form cyanuric acid.

Main purpose:

Melamine resin can be prepared by condensation polymerization with formaldehyde. It can be used in plastics and coating industry. It can also be used as anti folding and anti shrinkage treatment agent for textile fabrics. The modified resin can be used as metal coating with bright color, durability and good hardness. It can also be used for strong and heat-resistant decorative sheet, moisture-proof paper and gray leather tanning agent, adhesive of synthetic fireproof laminate, fixing agent or hardening agent of waterproof agent, etc. 582 melamine resin was prepared from melamine, formaldehyde and butanol. As a leveling agent for solvent based polyurethane coatings, the effect is particularly good.

The main raw material for manufacturing melamine formaldehyde resin is used as organic element analysis reagent, also used in the synthesis of organic and resin, as tanning agent and filler for leather processing. Melamine resin can be prepared by condensation polymerization with formaldehyde. It can be used in plastics and coating industry. It can also be used as anti folding and anti shrinkage treatment agent for textile fabrics. The modified resin can be used as metal coating with bright color, durability and good hardness.

Melamine resin made by condensation polymerization with formaldehyde is widely used in the manufacture and processing of wooden building formwork. It can be used for the waterproof of the formwork surface and the adhesion of wood core board to increase the reuse times of the formwork.

Packaging, storage and transportation:

Polypropylene woven bags can be used for packaging, lined with polyethylene inner bags; Polypropylene woven bags with polypropylene coating can also be used. The package shall be complete and the loading shall be stable. During transportation, ensure that the container does not leak, collapse, fall or damage. Mixed loading and transportation with oxidants, acids, etc. are strictly prohibited. During transportation, it shall be protected from sun exposure, rain and high temperature.
