polyaluminum chloride 1327-41-9 CAS NO.1327-41-9

Flocculant, mainly used for purification of drinking water and water treatment of special water, such as iron, fluoride, in addition to cadmium, in addition to radioactive contamination, in addition to floating oil. Also used for industrial wastewater treatment, such as printing and dyeing wastewater. In addition, also used for precision casting, medicine, papermaking rubber, leather, oil, chemicals, dyes. 2. Polyaluminium chloride in the surface treatment used as a water treatment agent. 3. Anti-sweat cosmetics main raw materials. 4. Part of the flocculant can be used for food additives.

 

1. Adsorption, aggregation, precipitation and other properties, poor stability of poly aluminum chloride. Toxicity and protection of corrosive, if accidentally splashed on the skin to rinse immediately with water. Production personnel to wear overalls, wearing masks, gloves, wear long rubber boots. Production equipment to be closed, the workshop ventilation should be good.

 

2. Corrosive. Heating to 110 ° C or more when the decomposition, release hydrogen chloride gas, and finally broken down into alumina; with the reaction of acid depolymerization, the degree of polymerization and alkalinity, and finally into the aluminum salt. Alkali and role can increase the degree of polymerization and alkalinity, and ultimately the formation of aluminum hydroxide precipitation or aluminate; and aluminum sulfate or other polyvalent acid salt mixture is easy to generate precipitation, can reduce or completely lose the coagulation properties.
