CAS No. 63148-62-9 is a polyaluminium chloride (PAC) powder, which is a highly efficient inorganic polymeric coagulant. It is widely used in water treatment, paper making, pharmaceutical, oilfield injection water, cosmetics, textile and other industries.


PAC is an inorganic polymer flocculant with high efficiency, wide application range and low price. The basicity of the product is from low to medium, and its alumina hydrolysis degree is high. It has the characteristics of large flocs, fast sedimentation and good filterability. It can be used as a flocculant in the treatment of drinking water and industrial waste water.


PAC powder is also used in papermaking and cosmetic industry. In papermaking, it can be used as a retention agent, filter aid, sizing agent and binder. In cosmetics, it can be used as a stabilizer, emulsifier and thickener.


In addition, PAC powder can also be used in oilfield injection water and textile industry. In oilfield injection water, it can reduce the content of suspended solids, so that the water can meet the requirements of the injection. In textile industry, PAC powder can be used as a dyeing agent, so that it can be used to make different colors of fabrics.


CAS No. 63148-62-9 is an important raw material for water treatment products. It has a wide range of applications and can meet the needs of different industries. It is an efficient and economical water treatment agent.
