Product Description
Cationic polyacrylamide (PAM) is a linear polymer compound that, due to its various active genes, can form hydrogen bonds by affinity and adsorption with many substances. Mainly a negatively charged colloid brought by flocculation, it has functions such as turbidity removal, decolorization, adsorption, and adhesion. It is suitable for the treatment of wastewater with high organic colloid content in industries such as dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic processing, and fermentation. It is particularly suitable for the dehydration treatment of urban sewage, urban sludge, papermaking sludge, and other industrial sludge.

advantages:
1. Strong water retention: prevents rapid drying of mortar;
2. Instant: stir in cold water before use, with a fast dissolution rate;
3. Environmental protection: no VOC, formaldehyde, etc; no odor;
4. Low cost: lower cost and less dosage compared to ordinary water retaining thickeners;
5. Good workability: The consistency, anti sagging and water retention properties of the mortar in dry powder mortar are characterized by small dosage, good water retention, high cohesion, and good durability.
Product application
(1) For sludge dewatering according to the nature of sludge can choose the corresponding model of this product, can effectively carry out sludge dewatering before sludge enters the press filter, when dewatering, the floc is large, non-stick filter cloth, not scattered during filtration, the flow mud cake is thicker, the dewatering efficiency is high, and the moisture content of the mud cake is below 80%.
(2) For the treatment of domestic sewage and organic wastewater, the suspended particles in the sewage with negative charge sewage flocculation and precipitation, clarification is very effective.
(3) For the treatment of the tap water from river water source has the advantages of small dosage, good effect and low cost, especially when combined with inorganic flocculant.
(4) Reinforcing agents and other auxiliaries for paper making. Improve the retention of fillers, pigments, paper strength.
(5) For oil field additives, such as clay swelling agent, oilfield acidification thickener.
(6) For textile sizing agent, slurry performance is stable, less pulp falling, fabric break rate is low, cloth surface clean.
