This product is an efficient, cheap, non-toxic inorganic polymer compounds, the liquid is colorless or light yellow transparent, solid for light yellow powder. Soluble in water, hydrolysis process accompanied by electrochemical, condensation, adsorption, precipitation and other chemical processes. This product is suitable for a wide range of pH values, large particles, fast settling speed, widely used in drinking water, domestic sewage, and industrial wastewater treatment.

1. Properties: colorless or yellow resinous solid. Its solution is colorless or yellowish brown transparent liquid, sometimes due to impurities and greyish-black mucus.

2. Solubility: easily soluble in water and dilute alcohol, insoluble in anhydrous alcohol and glycerin

3. It has the properties of adsorption, condensation and precipitation, and the stability of polyaluminum chloride is poor. Toxicity and protection corrosive, if accidentally splashed on the skin should be immediately washed with water. Production personnel should wear overalls, masks, gloves and rubber boots. Production equipment should be closed, workshop ventilation should be good.

3. Corrosive. When heated to more than 110℃, decomposition, release hydrogen chloride gas, finally decomposed into alumina; Depolymerization with acid reaction, so that the degree of polymerization and alkalinity is reduced, and finally into positive aluminum salt. The polymerization degree and alkalinity can be improved by the interaction with alkali, and finally the formation of aluminum hydroxide precipitate or aluminate; When mixed with aluminum sulfate or other polyvalent salts, it is easy to precipitate and can reduce or completely lose the coagulability.
