Characteristics of cationic polyacrylamide:
1. Cationic polyacrylamide has good water solubility and can be completely dissolved in cold water.
2, add a small amount of cationic polyacrylamide product, you can get great flocculation effect. In general, it only needs to add 0.01g / m ~ (3) of 0.01g / m ~ (-3) to 0.01g / m ~ (3).
3, the use of cationic polyacrylamide and inorganic flocculant can show greater effect. Uses of cationic polyacrylamide: Cationic polyacrylamide has the following functions: clarifying and purifying, sedimentation promoting, filtering promoting, thickening and other effects.
Cationic polyacrylamide applications:
1. As a flocculant, cationic polyacrylamide is mainly used in industrial solid-liquid separation processes, including settling, clarifying, thickening and sludge dewatering. The main industries in which cationic polyacrylamide is used are: municipal sewage treatment. Paper industry Food processing industry, petrochemical industry, metallurgical industry, mineral processing industry, dyeing industry and sugar industry and various industries wastewater treatment. Cationic polyacrylamide is also used in municipal sewage and sludge treatment of meat, poultry and food processing wastewater In sedimentation and sludge dewatering, the positive charge group can neutralize the electricity of negative charge organic colloid in sludge and the excellent bridging and condensing function of polymer, so as to make colloidal particles gather into bulk flocculants. Separated from its suspensions. The effect is obvious and the dosage is less.
2. Cationic polyacrylamide can be used as dry strength agent, retention aid and filter aid in papermaking industry. It can greatly improve the quality of paper, save the cost and improve the production capacity of paper mill. Can be directly associated with inorganic salt ions, fibers, and other organic high Molecules act as electrostatic bridges to enhance the physical strength of paper, reduce the loss of fibers or fillers, speed up water filtration, enhance, retain, and filter, and can also be used to treat white water, at the same time, Cationic polyacrylamide in deinking process Can have obvious flocculation effect.
3. Cationic polyacrylamide can improve the drainage property of the asbestos cement products and the strength of the billet in the fiber slurry (asbestos cement products), and improve the binding ability between the additive and the fiber in the insulating board.
4. Cationic polyacrylamide can be used as clarifier for mine wastewater and coal washing wastewater in mining and coal preparation industry.
5. Cationic polyacrylamide can be used to treat dyeing wastewater, leather wastewater and oily wastewater to remove turbidity and decolorize to meet the discharge standard.
6. Cationic polyacrylamide is helpful to the separation of gypsum in wet phosphoric acid process. Cationic polyacrylamide is used as flocculant in water treatment of waterworks with river water source.
