Product Introduction
Non-ionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Due to a certain number of polar groups in its molecular chain, it can adsorb suspended solid particles in water, bridging the particles or causing deep aggregation of particles through charge neutralization to form large flocs. Therefore, it can accelerate the sedimentation of particles in the suspension, significantly accelerating solution clarification and promoting filtration. It is mainly used for flocculation sedimentation and clarification treatment of various industrial wastewater, such as wastewater treatment in papermaking and pulp, wastewater treatment in mineral processing and metal smelting, wastewater treatment in steel plants and stone processing plants, etc.
Product Features
Because non-ionic polyacrylamide (NPAM) is a high molecular polymer or polyelectrolyte, its molecular chain contains a certain amount of polar genes that can adsorb suspended solid particles in water, bridging the particles to form large flocs, which accelerates the sedimentation of particles in the suspension. It has a very significant effect on accelerating solution clarification and promoting filtration. It is widely used in the treatment of chemical industrial wastewater and waste liquid, and municipal wastewater treatment. It is particularly suitable when wastewater is acidic. It can be used in combination with inorganic flocculants such as polyferric and polyaluminum inorganic salts.

Product Applications
1. Wastewater treatment agent: When suspended wastewater is acidic, it is more suitable to use non-ionic polyacrylamide as a flocculant. This is because PAM plays an adsorption bridging role, causing suspended particles to flocculate and precipitate, achieving the purpose of wastewater purification. It can also be used for the purification of tap water, especially in combination with inorganic flocculants, which has a good effect in water treatment, and shows significant effects in coal washing and mineral processing, leather plating, copper and iron plant water treatment.
2. Textile industry auxiliaries: Adding some chemicals can be formulated into chemical materials for sizing textiles.
3. Sand fixation: Dissolving non-ionic polyacrylamide into a 0.3% concentration and adding a crosslinking agent, spraying it on the desert can play a role in sand fixation.
4. Soil moisture retention agent: Used as a soil moisture retention agent and the basic raw material for various modified polyacrylamides.
