Product Description

Aluminium hydroxide, chemical formula Al(OH)3, is the hydroxide of aluminum. Because it is also acidic, it can be called monohydrate metaaluminum (HAlO2·H2O), but the actual aqueous solution reacts with the base to produce tetrahydroxy aluminate Al(OH)4-

Application

1, Flame Retardant
Aluminum hydroxide fillers are ideal, environmentally friendly, and environmentally friendly flame retardant fillers for plastics and organic polymers. Because the aluminum hydroxide filler is a pure white powder solid, the particle size can be processed according to the production, non-toxic and harmless, as a filler processing whiteness is not easy to change, with filling, flame retardant, smoke elimination three functions. When a plastic or polymer burns in contact with an external heat source, it can be divided into the following stages: heating, decomposition, fire, combustion, and spread. The principle of action of all flame retardants is to achieve the purpose of flame retardation by inhibiting one or several of the above combustion stages.

2, Papermaking Filler
Aluminum hydroxide filler is mainly used in the paper industry as surface coating, filler and the production of non-combustible paper. In foreign countries, as early as the fourth and 1950s began to use aluminum hydroxide filler as a coating pigment, but in China it is still blank. Aluminum hydroxide filler as a coating pigment has many advantages: high whiteness, fine particle size and uniform particle size distribution, flake shape, using it as a pigment can improve the whiteness, opacity, smoothness and ink absorption performance of coated paper. Using it instead of titanium dioxide can save the cost, improve the gloss and improve the mimeograph performance without reducing the whiteness and opacity of the paper.

3, Toothpaste Material
The main purpose of toothpaste is to remove dirt from the teeth without damaging the gums. This requires a neutral friction agent, and the mild friction properties of aluminum hydroxide fillers to clean and polish teeth just meet this requirement. And its chemical inertness is that it is compatible with other ingredients in toothpaste: In addition, aluminum hydroxide fillers have good coating properties, so aluminum hydroxide fillers are widely used in pharmaceutical toothpaste and STA high-grade toothpaste oil.

4, Chemical Raw Materials
Because aluminum hydroxide filler is a mass-produced, highly purified refined product, it can be quickly dissolved in strong acids and bases. Therefore, aluminum hydroxide filler is an important raw material for many kinds of aluminum salts. Such as alum, polyaluminum chloride. In the petrochemical industry, it can also be used to produce forest-free laundry powder, catalyst carrier, and other petrochemical industries.
