99% Anionic Polyacrylamide CAS 9003-05-8 Sewage Treatment Chemical

Anionic Polyacrylamide Flocculant Industrial Grade Sewage Treatment Chemicals

Polyacrylamide is a product with a wide range of applications, especially in the field of water purification. Polyacrylamide can also be called PAM. The models can be divided into anionic, cationic, nonionic and zwitterionic, of which cationic and anionic Use a little more.

The difference between cationic polyacrylamide and anionic polyacrylamide
1. Price factor: The price of cationic polyacrylamide is a bit more expensive than anionic polyacrylamide, but the higher the molecular weight, the more expensive.
2. Molecular weight: The molecular weight of anionic polyacrylamide is 6-18 million, while the molecular weight of cationic polyacrylamide is 8-12 million.
3. Different indicators: the main indicators of anionic polyacrylamide are molecular weight and degree of hydrolysis, and the main indicators of cation are ion degree and molecular weight.
4. PH value is different: the general anionic type is alkaline, and the cationic type is neutral.
5. The effect is different after use: After use, the flocs formed by cationic polyacrylamide are large and dense, while the flocs formed by anionic polyacrylamide are small and dispersed.
6. The use environment is different: Generally, anionic polyacrylamide is suitable for the suspension of positively charged inorganic suspended solids and the suspended particles are coarser (0.01-1mm). Cationic polyacrylamide is suitable for the suspension of negatively charged and organic substances. matter.
7. Different uses: Anionic polyacrylamide as a sewage treatment flocculant is mainly used to treat inorganic wastewater, in the treatment of coal mine wastewater, sand washing plants, coal washing plants, and iron and steel wastewater treatment. Cationic polyacrylamide as a sewage treatment flocculant is mainly used to treat organic wastewater, such as wastewater from food factories, wastewater from sugar factories, wastewater from MSG factories, and sludge dewatering. The direct point is that anionic polyacrylamide is more commonly used to treat wastewater, while cationic polyacrylamide is mainly used to treat sludge dewatering.

Polyacrylamide application areas:
1. The coal washing plant selects polyacrylamide to filter coal slurry to precipitate and concentrate tailings. Please choose anionic polyacrylamide, non-ionic polyacrylamide and low cationic polyacrylamide.
2. Please choose anionic polyacrylamide and non-ionic polyacrylamide for wastewater in the coating industry. For paint wastewater treatment, the traditional method is to directly coagulate the mixed wastewater. The treatment effect is unsatisfactory, the effluent quality is unstable, and it is difficult to meet the discharge standards.
3. Please use cationic polyacrylamide for biological treatment of waste liquid and sludge treatment in the dairy industry.
4. The electroplating wastewater containing cyanide is treated with anionic polyacrylamide, non-ionic polyacrylamide, and low-cation polyacrylamide.
5. Anionic polyacrylamide, low cationic polyacrylamide and non-ionic polyacrylamide are used to treat copper mine tailings wastewater.
