ALUMINIUM HYDROXIDE
admin2019-06-04 1189


Chemical formula: Al(OH) 3

Molecular weight: 78

Melting point: 300°C(lost water)

Physical and chemical properties:

A white colloidal substance almost insoluble in water. Acidic action is slow, persistent, strong, has a convergence effect, has mucosal protection effect, leads to constipation, does not produce CO2(carbon dioxide), has no acid rebound, and has non-alkalinemia. Aluminium hydroxide mainly has 325 orders, 800 orders, 1250 orders, and 5000 orders. White powder solid. Almost insoluble in water, react with alum to produce suspended matter in condensed water and adsorb pigments.

Product Use:

Aluminum hydroxide is the most widely used inorganic flame retardant additive. Aluminium hydroxide, as a flame retardant, can not only be flame retardant, but also prevent smoke, do not produce droplets, and do not produce toxic gases. Therefore, it has been widely used and the amount of use is increasing year by year. Scope of use: thermosetting plastics, thermoplastics, synthetic rubber, coatings and building materials industries. At the same time, aluminum hydroxide is also the basic raw material of aluminum fluoride necessary for the electrolytic aluminum industry, and aluminum hydroxide is also widely used in the industry.
