Cationic polyacrylamide is a water-soluble polymer formed by the polymerization of acrylamide aqueous solution, quaternary ammonium salt monomer, deionized water and other materials under certain conditions, followed by drying and grinding processes. Cationic polyacrylamide, due to the presence of a certain number of polar groups in its molecular chain, can adsorb solid particles suspended in water, bridging particles or neutralizing charges, causing particles to aggregate and form large flocs. Cationic polyacrylamide has various active functional groups that can form hydrogen bonds by affinity and adsorption with many substances, thereby accelerating solid-liquid separation and promoting filtration efficiency.

1、 Characteristics of cationic polyacrylamide:

Cationic polyacrylamide has good water solubility and low charge, and can be completely dissolved in cold water. It requires less medication during the addition process, and a small amount of the product can achieve great flocculation effect. It is often used in the same way as polymeric ferric sulfate, polymeric chloride, and iron salts, and the effect is obvious.
2、 Application of cationic polyacrylamide:

Cationic polyacrylamide is mainly used for flocculation and sedimentation of various industrial and domestic wastewater, sedimentation and clarification treatment, sludge pre concentration, and sludge dewatering. For example, the treatment of wastewater from alcohol factories, beer factories, monosodium glutamate factories, sugar factories, meat factories, beverage factories, textile printing and dyeing factories, as well as the concentration and dehydration of sludge from municipal sewage treatment plants. It plays a particularly prominent role in acid beneficiation, wastewater treatment in the paper industry, sedimentation and clarification of various types of water, and sludge dewatering. It is commonly used in centrifuges and belt conveyors for excellent results.

3、 Precautions for using cationic polyacrylamide:
1. Contact personnel must wear protective equipment when using polyacrylamide, and the skin contact area should be immediately washed with clean water.

2. Maintain a dry bath in the workplace and avoid sprinkling polyacrylamide on the ground. In case of slippery conditions, it should be cleaned in a timely manner to prevent slipping and falling.

3. Try to prevent moisture absorption and exposure to sunlight.

4、 Bilang cationic polyacrylamide technical service:

Shanghai Bilang Environmental Protection Technology Co., Ltd. provides users with the selection of cationic polyacrylamide products, small-scale experiments, factory trials, and comprehensive technical services.
5、 Packaging and transportation of Bi Lang cationic polyacrylamide:
1. 25KG composite bag or 750KG large package

2. Avoid direct sunlight exposure.

6、 Application process of cationic polyacrylamide:

1. Determine the specific usage grade of cationic polyacrylamide through small-scale experiments.

2. Prepare an aqueous solution with a concentration of 0.1~0.3%, and use neutral water that does not contain salt impurities.

3. Evenly sprinkle this series of products into the stirred water, and control the stirring speed at 100-300rpm. Moderate heating (<60 ° C) can accelerate dissolution

4. Select the optimal pH value and dosage of cationic polyacrylamide through experiments

5. When adding cationic polyacrylamide, the mixing with the treated liquid should be accelerated. After the appearance of flocculants, the stirring speed should be slowed down to promote the growth of flocculants and the accelerated settling of the treated liquid.
