Introduction of aluminum sulfate

Aluminum sulfate is a white shiny crystals, granules or powder, sweet, stable in air. 86.5 ℃ when the loss of part of the crystal water, 250 ℃ lose all crystal water. Violently expanding when heated and become a sponge-like material. Thermal decomposition of red burn sulfur trioxide and aluminum oxide. When the relative humidity of about 25% lower weathering. Soluble in water, practically insoluble in ethanol, the solution is acidic. Long after boiling insoluble basic salt precipitation. The relative density of 1.62. Aluminum sulfate is a widely used industrial reagent, usually with alum (potassium aluminum sulfate dodecahydrate both) confusion. Aluminum sulfate is often used as flocculant for purifying drinking water and wastewater treatment equipment which is also used in the paper industry.

Health hazards: the eyes, mucous membranes have a stimulating effect. Swallowed a large number of aluminum sulfate oral and stomach irritation effect. Explosion hazard: The product is flammable, irritating.
