Hongzheng ISO14001 PAM Polyacrylamide,
88% PAM Polyacrylamide,
PAM Polyacrylamide/ Cation Polyacrylamide/ Anion Polyacrylamide/ Nonionic PAM/ Zwitterionic PAM
Polyacrylamide (PAM), polyacrylamide PAM is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce the friction resistance between liquids, can be divided into non-ionic according to cation, Anion, Nonionic and Zwitterionic types. It is widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, textile, construction and other industrial sectors.

1. Cation Polyacrylamide:
Cation PAM town and factory sewage treatment. Urban and factory sewage often uses active sludge treatment methods. Biochemical sludge is often a highly hydrophilic colloid, and the water contained in it is extremely difficult to remove. If cationic polyacrylamide flocculants are used, good desorption can be achieved. Moisture removal effect.
2. Anion Polyacrylamide:
Anionic PAM flocculant is suitable for positively charged slurries on the surface of the particles. There is also a cationic contrast. Its molecular weight is relatively high, and the molecular stretch in clean water is relatively large, so it has good particle flocculation characteristics.
It can be effectively used for the sedimentation and separation of floating minerals. In addition to waste water treatment in ironmaking blast furnaces, aluminum processing, paper, etc., it is also used in the primary treatment of urban sewage treatment.
3. Non-anionic Polyacrylamide:
Non-ionic PAM polyacrylamide is suitable for the separation of floating substances in organic and inorganic assimilation states, and the solution is acidic or neutral.
Non-ionic polyacrylamide products can be used as textile printing and dyeing auxiliaries. When a lot of other chemical products are added, they can be formulated as chemical sizing agents for printing sizing to increase adhesion, penetration and desizing properties, so that the fabrics have anti-sizing properties. Electrostatic property, reduce sizing rate, reduce grout spots.
Non-ionic polyacrylamide is mainly used as a waste water treatment agent, suitable for acidic suspensions, and is most suitable for use as a flocculant. At this time, polyacrylamide has the effect of adhesion and bridging, flocculating and settling the floating charges to achieve water purification. purpose.
4. Zwitterionic Polyacrylamide:
Zwitterionic polyacrylamide PAM is suitable for sewage treatment with floating properties and varying pH values.
Flocculants such as zwitterionic polyacrylamide can be used within a large limit of PH value, and can also be used as strong sulfuric acid leaching materials or to recover valuable heavy metals from metal-containing acid catalysts. Main use: Oilfield profile control and water shutoff agent, combined with crosslinking agent, stabilizer, coagulant, and become a high-strength coagulant glue water shutoff agent with important polymerization and resin gel.
