An Simple Introduction to Zwitterionic Polyacrylamide
Zwitterionic Polyacrylamide is the amide of ethylene and ethylene based cationic monomer a crylamide monomer, hydrolysis of copolymers formed. Infra-red spectroscopy, which linked after hydrolysis of acrylamide is not only on "carboxyl group of anionic, but ethylene based cationic charge. Therefore constitutes both positive charge on the molecule chain, and irregular negative charge of the zwitterionic polymer.
Zwitterionic Polyacrylamide molecules containing cation-and anion radicals, hydrolysis of copolymers formed. Advantage is with the General features of cationic flocculant, is used for acid leaching ore or metal recovery of valuable metal in the acidic catalyst. Amphoteric is by no means anionic and cationic hybrid. If the cationic polyacrylamide with anionic polyacrylamide used reaction produces precipitation occurs. Zwitterionic product is ideal.
Zwitterionic Polyacrylamide is mainly used as flocculants: suspended particles, thicker, high concentration, particle with a positive charge, water PH value is neutral or alkaline water, due to the anion polyacrylamide Pam molecular chain containing a certain amount of suspension of solid particles in the polar base can be adsorbed water, make the bridge between particles to form larger flocs. So it accelerates particles in suspension of settlement, there is a very clear clarification accelerated solution, filters and other effects. This product is widely used in chemical industrial wastewater, wastewater treatment, and municipal sewage treatment.

Kegao Chemical (APAM supplier & CPAM manufacturer ) was founded in Jan., 1998. Until now, the enterprise has become an enterprise which owns strong R&D ability, production equipments, completed test method. With the accumulation of experience and competitiveness of these years, our annual production of Polyacrylamide has reached 30,000 now, including anionic polyacrylamide PAM, cationic APAM, non-ionic PAM, zwitterionic PAM, low molecule PAM and super-high molecule PAM, etc. They are widely used in oil field, water treatment, coal washing, ore dressing, and papermaking industry, etc.
