Product Description

Cationic polyacrylamide (CPAM) is a linear polymer compound. Because it has a variety of active groups, it can form hydrogen bonds with many substances by affinity and adsorption. Mainly flocculate negatively charged colloids, with functions such as turbidity removal, decolorization, adsorption, adhesion, etc. It is suitable for organic colloid content in dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil field, aquatic product processing and fermentation and other industries. High wastewater treatment, especially suitable for dewatering treatment of municipal sewage, municipal sludge, paper sludge and other industrial sludge.


Product form
Cationic polyacrylamide can be divided into two forms: solid particles and emulsions according to different forms. In 2013, the most widely used in the market was solid particles, while cationic polyacrylamide emulsions, as a new form of product, were rarely used in the market.

1. It has good water solubility and can be completely dissolved in cold water.

2. Adding a small amount of cationic polyacrylamide product can get a great flocculation effect. Generally, it only needs to add 0.01~10ppm (0.01~10g/m) to give full play to the effect.

3. Simultaneous use of cationic polyacrylamide products and inorganic flocculants (polyferric sulfate, polyaluminum chloride, iron salts, etc.) can show greater effects.


The so-called hydrolysis degree of polyacrylamide refers to the ability of weak ions in polyacrylamide solution to combine with water to form weak base or weak acid, or the strength of weak acid and weak base in polyacrylamide aqueous solution. weak. For strong acids and strong bases, the higher the degree of ionization, the stronger the acidity and alkalinity, and the weaker the degree of hydrolysis. For some soluble polyacrylamides, the higher the ionization degree, the more ionized ions, and the weaker their hydrolysis degree. Generally, the higher the degree of ionization, the weaker the degree of hydrolysis; on the contrary, the lower the degree of ionization, the greater the degree of hydrolysis.



Since cationic polyacrylamide has the following effects:

1. Clarification and purification;

2. Subsidence promotion;

3. Filtration promotion;

4. Thickening and other functions.

Therefore, it can fully meet the requirements in waste liquid treatment, sludge concentration and dehydration, mineral processing, coal washing, papermaking and so on.


1. PAM has a unique decolorization ability and is mainly used in the decolorization of high-chroma wastewater from dye factories. The applicable dyes are reactive, acid and disperse dyes.

2. It can also be used for the treatment of industrial wastewater such as textile, printing and dyeing, ink and so on.

3. The decolorization rate of this product to wastewater can reach more than 95%, and the removal rate of COD is between 40-70%.
