Cationic polyacrylamide (CPAM) is a linear polymer compound. Because it has a variety of active groups, it can be affinity and adsorb with many substances to form hydrogen bonds. It mainly flocculates negatively charged colloids and has the functions of turbidity removal, decolorization, adsorption and adhesion, etc. It is suitable for dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic product processing and fermentation and other industries. Organic colloid content High wastewater treatment, especially suitable for dehydration treatment of urban sewage, municipal sludge, paper sludge and other industrial sludge.
Cationic polyacrylamide technical indicators
| Appearance | white particles |
| Solid content | ≥88% |
| Molecular weight | 8-12 million |
| Water insoluble matter | ≤2% |
| Residual unit | ≤0.1% |
| Cationic charge density | 10-70 % |
| Dissolution time | ≤60 minutes |
Features
1. Good water solubility, can be completely dissolved in cold water.
2. Adding a small amount of cationic polyacrylamide products can get a great flocculation effect. Generally only need to add 0.01~10ppm (0.01~10g/m3) to fully play its role.
3. Using cationic polyacrylamide products and inorganic flocculants (polyferric sulfate, polyaluminum chloride, iron salt, etc.) at the same time can show greater effects.
