(Factory direct sale)aluminium sulphate for water treatment
1.properties
White luster crystal, granule or powder. Taste sweet. In the air stability. 86.5 °C losing part water of crystallization, 250 °C lost all water of crystallization. When heating violent expansion and becomes spongy material. Burn the red heat when decomposition for sulfur trioxide and alumina. When the relative humidity about low 25% when weathering. Soluble in water, hardly soluble in ethanol, solution to become acidic. Long after boiling not soluble alkali salt precipitation. Relative density 1.62. Aluminum sulfate is a widely used industrial reagent, usually with alum (both twelve hydrated aluminium potassium sulfate) confusion. Aluminum sulfate is often as flocculating agent, used in purifying drinking water and sewage treatment equipment in the middle, also used in paper industry.
