Cationic polyacrylamide
I. Overview:
Cationic polyacrylamide is a water-soluble polymer. Because its molecular chain contains a certain number of adsorption and polar groups, it can adsorb solid particles suspended in water, bridge between particles and neutralize charges, so that particles aggregate to form large flocs. It has the effects of accelerating solid-liquid separation, promoting filtration, etc. It is mainly used for flocculation and sedimentation of various industrial and domestic sewage, sedimentation and air flotation; sludge concentration and sludge dewatering.
II. Product performance index:
| Model | Appearance | Solid content ( % ) _ | Molecular weight (10,000) | Ionicity % |
| Cationic | White powder | ≥ 90 | 400-1300 | 0-80 |
III. Product Features:
1. It has good water solubility and can be completely dissolved in cold water.
2. Adding a small amount of this series of products can get a great flocculation effect. Generally, only 0.01~10ppm (0.01~10g/m3) needs to be added to give full play to the effect.
3. Simultaneous use of this series of products and inorganic flocculants (polymeric ferric sulfate, polyaluminum chloride, iron salts, etc.) can show greater effects.
IV. Function:
This series of products has a very strong flocculation effect, because it has:
1. Clarification and purification;
2. Subsidence promotion;
3. Filtration promotion;
4. Thickening and other functions.
In waste liquid treatment, sludge concentration and dewatering, mineral processing, coal washing, papermaking, etc., it can fully meet the requirements of various fields.
V. How to use:
1. When using, it should be prepared into an aqueous solution with a concentration of 0.1~0.3%, and it is advisable to use neutral water without salt impurities.
2. When dissolving, evenly sprinkle this series of products into the stirring water, and control the stirring speed at 100~300rpm. Appropriate heating (< 60°C) can accelerate dissolution.
3. Adjust the PH value of the liquid to be treated, so that this series of products can fully play a role (select the best PH value and the dosage of this series of products through experiments).
4. When adding the solution of this series of products, the mixing with the liquid to be treated should be accelerated. After the flocs appear, the stirring speed should be slowed down to facilitate the growth of the flocs and accelerate the sedimentation.
VI. Matters needing attention:
1. Operators should wear protective equipment and wash with water after skin contact.
2. Always wash with water at the site of use to prevent slipping and injury.
3. This series of products should be sealed and stored in a cool and dry place.
