Use Of Multiple Varieties Of Aluminum Hydroxide

Aluminium hydroxide, chemical formula Al(OH)3, is the hydroxide of aluminium. Aluminum hydroxide can react with acids to form salts and water as well as strong bases, and is therefore also an amphoteric hydroxide. The chemical formula Al(OH)3 is the hydroxide of aluminum. It is also called aluminic acid (H3AlO3) because of its acidity. But the actual reaction with the base forms a tetrahydroxy aluminate ([Al(OH)4]-). Therefore, it is generally regarded as monohydrate metaaluminic acid (HAlO2·H2O), according to the use of industrial grade and pharmaceutical grade two.

Used as a filling material for carpet papering, glistening latex foam and adhesive

The application of aluminum hydroxide in carpet industry mainly utilizes the flame-retardant filling properties of aluminum hydroxide. All latex used in the blanket industry comes in two forms, a binder and a foam. The carboxylated latex layer is a adhesive used to attach carpet fibres bound to a mesh paper. The latex foam is applied to the surface of the carpet to achieve the desired thickness. Its curing is done in the oven at 120~150℃. Typically, binder ratios are 75 to 250 parts of aluminum hydroxide per 100 parts of latex, and 20 to 150 parts of aluminum hydroxide per 100 parts of latex in foam. In general, the aluminum hydroxide used in carpet is D50<20μm fine aluminum hydroxide.

Papermaking filler

Aluminum hydroxide is mainly used in the paper industry as surface coating, filler and the production of paper. In foreign countries, as early as 40 and 50 years have begun to develop and use aluminum hydroxide as a coating pigment, but in our country is still blank. Aluminum hydroxide as a coating pigment has many advantages: high whiteness, fine particle size and uniform particle size distribution, flake crystal shape, using it as a pigment can improve the whiteness of coated paper, opacity, flatness and ink absorption performance. Using it instead of titanium dioxide, without reducing the whiteness and opacity of the paper, can save the cost, improve the gloss of the paper, improve the printing performance.

Aluminium hydroxide for medical use

Aluminum hydroxide is one of the main components of stomach medicine, and aluminum gel is the neutralizer of stomach acid, which is the traditional medicine to treat stomach diseases. Some new special stomach drugs now contain aluminum hydroxide.

The production of aluminum hydroxide by aluminum hydroxide manufacturers is a large-scale process. In the chemical industry, the requirements for aluminum hydroxide are also very high. Aluminum hydroxide is an important raw material in many chemical industries.
