Polyacrylamide also plays an important role in the field of sewage treatment and industrial wastewater treatment. Increasingly strict regulations have promoted the development of the water treatment industry. The sewage treatment field has not been affected by the financial crisis, but has shown a good growth momentum. New sewage treatment markets have emerged in North Africa, including countries such as Morocco, Tunisia, Algeria, and Egypt, while other countries, such as Saudi Arabia and Qatar, are also increasing investment in privatization of water treatment. In terms of industrial wastewater treatment, coal mining and thermal power station construction provide a huge business space, and the increasing attention to water reuse technology is also a market driving factor.


Because polyacrylamide is a high molecular water-soluble polymer, it has good flocculation and can reduce the friction resistance between liquids. In addition to the application of acrylamide in the petroleum industry, it also has a wide range of applications in the sewage treatment industry, paper industry, sugar industry, coal washing and metallurgical industries. Below we will specifically introduce other application areas.

Water-sensitive gel: The swelling property of polyacrylamide hydrogel in water undergoes a sharp mutation at a certain critical temperature with a slight change in humidity, and the volume change can reach tens to hundreds of times. This property can be applied to the concentration of some aqueous solutions without the use of high temperature, which is valuable for the extraction of some organic or biological substances. Food processing: Polyacrylamide can be used as chemical additives in the sugar industry. In addition, it can be used for the purification of various meat, fruit and vegetable washing water and the clarification of fruit wine and beer. The use of high molecular weight polyacrylamide (hydrolysis degree 25 %-30%), as a flocculant, it can be used for clarification of syrup, which can remove as much non-sugar content as possible to improve quality. Electroplating industry: In the electroplating solution, adding polyacrylamide can homogenize the metal precipitation and make the coating brighter. Water-absorbent resin: Super-absorbent resin has been widely used in industry, agriculture and daily life. This type of polymer gel has high strength, and its water absorption can reach hundreds of times or even thousands of times its own weight. As the demand for super absorbent resins for the production of diapers and sanitary napkins has grown, the demand for polyacrylamide has also grown rapidly.



It is widely used in petrochemical, metallurgy, coal, mineral processing and textile industries, as a precipitation flocculant, oilfield water injection thickener, drilling mud treatment agent, textile slurry, paper enhancer, fiber modifier, soil conditioner , Soil stabilizer, fiber paste, resin processing agent, synthetic resin coating, adhesive, dispersant, etc.

about the molecular weight compounding situation of anionic polyacrylamide

Before use, the best dosage should be determined through experiments. If the dosage is too low, it will not work, and if the dosage is too high, it will have a counterproductive effect. This is because more than a certain concentration, PAM not only does not flocculate, but also stabilizes dispersion.

Non-ionic PAM is used as a highly selective flocculant in low-solid drilling muds using bentonite, because it can flocculate the drilled cuttings while keeping the bentonite in a dispersed state.

A lower concentration should be used when dosing to ensure uniform mixing.

Anionic PAM is a bridge formed by entanglement of many fine particles or oil beads in sewage through the long chain of its polymer. It is a flocculant with very strong flocculation ability, and its flocculation speed is faster than anionic PAM. In the treatment of oily sewage in oil fields, it is usually used in conjunction with aluminum salts.
