Can Polyaluminum Chloride Be Used In The Paper Industry?
As an efficient flocculant, polyaluminum chloride has been widely used in water treatment processes. In recent years, polyaluminum chloride has also been increasingly used in the paper industry.
Polyaluminium chloride is a prefabricated hydrolyzate, which is an intermediate product of the hydrolysis-polymerization-precipitation process of aluminum salts under certain controlled conditions.
PAC can be used as an efficient water treatment agent or as a neutral sizing agent for rosin in the wet end of papermaking. Precipitants have the tendency to replace traditional aluminum salts (such as aluminum sulfate). Since the 1960s, polyaluminium chloride, as a new high-efficiency flocculant, has gradually developed into the main agent in the coagulation process in water treatment. It is a variety with mature industrial production technology, high efficiency and wide application.
Whether used as a flocculant in water treatment or used in the wet end of , polyaluminum chloride is a new, highly efficient prefabricated inorganic polymer hydrolyzate. Its wide range of applications and remarkable efficiency are unmatched by traditional aluminum salts.
Polyaluminium chloride is used in the papermaking industry, in addition to its partial use in sewage and clean water treatment (in papermaking). Its main use is as a rosin neutral sizing precipitant and retention and filtering aid. In addition, it is also used to control resin barrier and as a capture agent for anionic impurities, etc.
