Cationic polyacrylamide is commonly used
1, as a flocculant, cationic polyacrylamide is mainly used in industrial solid-liquid separation processes, including sedimentation, clarification, concentration and sludge dehydration. The main application industries are: urban sewage treatment, paper industry, food processing industry, petrochemical industry, metallurgy industry, mineral processing industry, dyeing industry, sugar industry and various industrial wastewater treatment. It is used for sludge precipitation and sludge dehydration in the treatment process of municipal sewage, meat, poultry and food processing wastewater. Through its positive charge groups, the electricity of negatively charged organic colloids in the sludge and the excellent bridge coagulation function of the polymer, the colloidal particles are promoted to gather into large flocculates and separated from the suspension. The effect is obvious, the addition amount is small.
2, in the paper industry, cationic polyacrylamide can be used as paper dry strength agent, retention agent and filter aid, which can greatly improve the quality of paper making, save costs, and improve the production capacity of paper mills. Electrostatic Bridges can directly interact with organic polymers such as inorganic salt ions and fibers to enhance the physical strength of paper, reduce the loss of fibers or fillers, accelerate water filtration, enhance, retain and filter, and can also be used for white water treatment. At the same time, it can play an obvious flocculation role in the deinking process.
3, fiber mud (asbestos-cement products) can improve the drainage of asbestos-cement products, improve the strength of asbestos slab; In the insulating board, the binding ability of additives and fibers can be improved.
4, mine wastewater mountain wastewater, coal washing wastewater clarifying agent.
5, cationic polyacrylamide can be used for dyeing wastewater, leather wastewater, oily wastewater treatment, to achieve discharge standards.
6, in phosphoric acid purification, contribute to the separation of gypsum in the wet phosphoric acid process.
7. Flocculant for water treatment in waterworks.
