Cationic Polyacrylamide PAM

Cationic Polyacrylamide PAM

I.Properties and Uses

This product is a white small granule or powder formed by copolymerization of cationic monomers and acrylamide, followed by granulation, drying, and crushing. Cationic Polyacrylamide (CPAM) is a linear polymer compound. Due to its various active groups, it can form hydrogen bonds through affinity and adsorption with many substances. It mainly flocculates negatively charged colloids and has functions such as turbidity removal, decolorization, adsorption, and bonding. It is suitable for wastewater treatment with high organic content in industries such as dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic product processing, and fermentation. It is particularly suitable for the dehydration treatment of urban sewage, urban sludge, papermaking sludge, and other industrial sludges.

II. Technical Indicators

III.Usage Method

1.First, determine the product specification and dosage through small-scale testing.

2.During use, the solution preparation concentration is generally 1-3‰. The dissolution water temperature should be controlled between 18-40°C, and the stirring speed should generally be maintained at 80-200 r/min. It is advisable to use neutral, low-hardness water for preparation.

3.Since iron ions are catalysts for the chemical degradation of polyacrylamide, contact with iron ions should be avoided as much as possible during the preparation, transportation, and storage of polyacrylamide. It is recommended to use stainless steel, plastic, or carbon steel products coated with resin.

4.Polyacrylamide aqueous solutions should be prepared and used immediately. If the dissolved solution is left standing for a long time, its performance will gradually decline depending on the water quality conditions.
