Polyacrylamide(PAM) include anion (APAM), cation (CPAM), non-ionic (NPAM) and zwitterion (ACPAM). Polyacrylamide is mainly used in coal washing plant,printing and dyeing factory,farm,sewage treatment plant,oil field,concentrating mill,etc.
Polyacrylamide (PAM) is one of the most widely used water-soluble polymers. Anionic polyacrylamide (APAM) include: ultra high molecular weight(over 25 million), high molecular weight(up to 20 million), medium molecular weight(about 16 million), Solid content over 89% .
Nonionic Polyacrylamide (NPAM) include: medium molecular weight(over 15 million), low molecular weight(up to 8 million), Solid content over 89%.
CPAM is a type of polyacrylamide that has a positively charged functional group, such as amino or quaternary ammonium, which makes it highly effective in binding with negatively charged particles, such as clay, silt, and organic matter in water. |
The polyacrylamide is water -solution high polymer with good flocculanting activity can reduce the friction resistanca between liquid.
2. Adhesiveness: The impurities can be bonded together to precipitate to the bottom.
3 Thickening Agent: In neutralizing acidic conditions have thickening effect, if the PH value is more than 10 PAM easy hydrolysis.
Among the organic polymer flocculants, anionic polyacrylamide (APAM) has a long history, mature technology and wide application, so it is also paid more attention. The advantages of anionic polyacrylamide are: the cost is much lower than cationic polyacrylamide and amphoteric polyacrylamide, the flocculation effect is good, and the process is mature.
In addition, due to the active amide group on the polymer chain, the anionic carboxyl group can physically and chemically react with a variety of substances, so that it has excellent surface activity in addition to polymer chain characteristics, and is widely used in papermaking, mineral processing, oil extraction, metallurgy, building materials, food processing, water treatment and other industries.

Application of Cationic polyacrylamide :
Sewage treatment:
City sewage treatment, food processing, metallurgy, dyeing industry, mineral processing industry, sugar industry and various kinds of industrial wastewater treatment.
Paper industry:
Paper industry can be use for paper dry strength agent, retention agent, filter aid,improving paper quality and paper production capacity.
Oil industry:
Polyacrylamide is widely used in oilfield chemicals such as clay anti-expansion agents, thickeners for oil field acidification, and oily wastewater treatment agents.
Application of Anionic polyacrylamide :
1.Coal washing: APAM used for centrifugal separation of coal washing tailings, used in the precipitation and filtration of coal powder and slime, can increase the filtration rate and the recovery rate of coal powder;
2.Bamboo incense, mosquito coils, sandalwood, etc., dry mix can also release viscosity;
3.Piling, drilling, washing, mixing and other related fields;
4.Other areas where the granules are required to be fine and the tack time is required to be fast.
Application of Nonionic polyacrylamide :
1.Sewage treatment agent: It is most suitable when the sewage quality is acidic;
2.Textile industry: NPAM add some other chemicals that can be configured as chemical slurries for textile sizing;
3.Sand-fixing sand: Add a glue joint agent at a certain concentration, spray it on the desert, and solidify into a film to prevent sand and sand;
4.NPAM can also be used as a soil moisturizer for construction, building glue, interior wall coatings, etc.
