Amphoteric polyacrylamide is a linear polymer formed by ternary copolymerization of cationic monomer, acrylamide monomer and hydrolytic agent. With decolorization, adsorption, turbidity, adhesion and other functions. The product is an amphoteric irregular polymer with both positive and negative charges on the molecular chain. The appearance of the product is white fine particles can be powder solid. The advantage is that it has the use characteristics of general flocculant and has better performance. These flocculants can be used over a wide range of PH values, have higher filter water, lower cake moisture content, and can also be used for strong acid leaching of ores or recovery of valuable metals from acidic catalysts containing metals. The amphoteric type is not a mixture of anionic and cationic types.Â
