Industrial grade polyaluminum chloride

Polyaluminium chloride is a water purification material, inorganic polymer coagulant, also referred to as polyaluminum, abbreviated as PAC, molecular weight produced by the bridging action of hydroxide ions and the polymerization of polyvalent anions. Larger, higher-charged inorganic polymer water treatment agent. In terms of morphology, it can be divided into solid and liquid. Solids are divided into sepia, beige, gold and white according to the color. The liquid can be colorless, transparent, yellowish, light yellow to yellowish brown. Different colors of polyaluminum chloride also have great differences in application and production technology.

Uses:
1. It is a flocculant, mainly used for purifying special water treatment of drinking water and water supply, such as iron removal, fluorine removal, cadmium removal, radioactive pollution, and floating oil. Also used in industrial wastewater treatment, such as printing and dyeing wastewater. In addition, it is also used in precision casting, medicine, paper rubber, leather, petroleum, chemical, and dyes.
2. Polyaluminum chloride is used as a water treatment agent in surface treatment. 3. Main raw materials for antiperspirant cosmetics. 4. Part of the flocculant can be used for food additives

Properties:
1. It has the properties of adsorption, coagulation and precipitation, and the stability of polyaluminum chloride is poor. Toxicity and protection are corrosive. If it is accidentally splashed on the skin, rinse it off immediately with water. Production personnel should wear overalls, wear masks, gloves, and long rubber boots. The production equipment should be sealed and the workshop should be well ventilated.
2. It is corrosive. When heated to above 110 ° C, it decomposes, releases hydrogen chloride gas, and finally decomposes into alumina; it depolymerizes with acid to reduce the degree of polymerization and alkalinity, and finally becomes a normal aluminum salt. The action with alkali can increase the degree of polymerization and alkalinity, and finally form aluminum hydroxide precipitate or aluminate; when mixed with aluminum sulfate or other polyvalent acid salts, precipitates are easily formed, which can reduce or completely lose the coagulation property.
