Raw materials Aluminium trihydrate is purified from bauxite. Commercial bauxite (30-75% Al2O3) deposits occur in Australia, Jamaica, France, Guyana, Guinea, the USA and Brazil. Bauxite ore is dissolved in strong caustic soda to form sodium aluminate. The aluminium trihydrate is then precipitated by neutralisation (usually with carbon dioxide) or by autoprecipitation (the Bayer process). The […]
Aluminium sulfate (Al2(SO4)3), commonly called alum, is produced as white crystals which are non-combustible and soluble in water. This dry hydrate (Al2(SO4)3.14H2O) is 17% Al2O3 and is also sold as a 47% w/w aluminium sulfate solution which is 8% Al2O3. It is also sold in solid form as kibbled, ground or dust. Aluminium sulfate, Al2(SO4)3, […]
Solid surface is a man-made material usually composed of a combination of Alumina Hydroxide (ATH), acrylic, epoxy or polyester resins and pigments. It is most frequently used for seamless countertop installations.Solid surface was first introduced by DuPont in 1967 under the name of Corian. Since the expiration of their patent other manufacturers have entered the […]
The main raw materials of photovoltaic glass are: silica sand, soda ash, dolomite, limestone, aluminum hydroxide, mirabilite, sodium nitrate, sodium pyroantimonate, and some recycled broken glass.Due to the special requirements for light transmittance of photovoltaic glass, it is generally required that the iron content of each raw material is low, and the raw material is […]
Poly Aluminum Chloride/PAC has the properties of adsorption, agglomeration, and precipitation. It has poor stability and corrosiveness. If it accidentally splashes on the skin, it must be rinsed off immediately with water. Production worker should wear overalls, masks, gloves, and rubber boots. Poly Aluminum Chloride/PAC has the advantages of good spray drying stability, wide adaptability […]
The original aluminum hydroxide is also called natural mineral powder, its content in the three components also occupy a larger proportion.In better artificial stone, its content occupies 30%.With polyester resin as the base material, and then add aluminum hydroxide and some environmental protection paint, make the artificial stone surface texture is very strong, large imported […]
