Polyacrylamide can be divided into cationic, anionic, nonionic and zwitterionic, with a molecular weight between 4 million and 20 million.The appearance of the product is a white powder, soluble in water, and easy to decompose when the temperature exceeds 120℃.Polyacrylamide can be divided into anionic, cationic, nonionic and zwitterionic.

1. Cationic polyacrylamide flocculant is mainly used in industrial solid-liquid separation processes, including precipitation, clarification, concentration and sludge dewatering.It is mainly used in industrial and urban sewage treatment, paper industry, food processing, petrochemical industry, metallurgical industry, mineral processing, printing and dyeing industry, sugar industry and various industrial wastewater treatment.It is used to treat sludge precipitation and sludge dewatering processes in urban sewage, meat, poultry and food processing wastewater.It can neutralize the organic colloids and polymers with negatively charged and positively charged groups in the sludge, and promote the aggregation of colloidal particles into large flocculations and the separation of suspensions.The effect is obvious and the dose is reduced.

2. Cationic polypropylene fiber pulp can improve the drainage performance of molded asbestos cement products and improve the strength of asbestos board; in the insulating board, the adhesion between additives and fibers can be improved.

3. It is used for wastewater from alcohol plants, breweries, monosodium glutamate plants, sugar plants, meat products plants, beverage plants, textile printing and dyeing plants, and various sewage treatment plants.It contains a variety of organic solvents, as well as inorganic and organic sulfides, hydrocarbons, chlorine, petroleum, mercury and other harmful environments, and can be flocculated with PAM before discharge.It can also be used as a mud treatment agent in the textile printing and dyeing process, such as selective water plugging agent, thickener, softener, antistatic agent and water injection agent.

4. Paper dry strength agents, retention aids and filter aids that can be used in the paper industry can greatly improve paper quality, save costs and increase the production capacity of paper mills.It can be directly used for static electricity between inorganic ions, organic polymer fibers and other materials, thereby improving the physical strength of the paper, reducing the loss of fibers or fillers, speeding up water filtration, and has an enhanced effect on retention and filtration.It can also be used for water treatment.At the same time, it has obvious flocculation effect in the deinking process.

5. Cationic polyacrylamide and coal washing wastewater clarifiers can be used as mine wastewater.

6. It can be used for the treatment of printing and dyeing wastewater, the turbidity and decolorization of leather wastewater and oily wastewater, and meet the discharge standards.

7. It is used for water purification, oil-water emulsification, oily wastewater treatment, wastewater recovery system and sludge dewatering; polyacrylamide can effectively reduce the friction of liquids.Adding a small amount of polyacrylamide to the water can reduce friction by 50-80%.8. Cationic polyacrylamide helps to separate gypsum wet phosphoric acid.9. Cationic polyacrylamide is used as a flocculant for water treatment in water plants.Cationic polyacrylamide powder Cationic polyacrylamide 10. It is usually used in wastewater treatment and organic wastewater treatment: Usually, the flocculation and precipitation of negatively charged particles in wastewater are suspended.According to the acidic or alkaline medium of cationic flocculation, it is very effective to use electronegative properties to clarify and treat sewage as soon as possible.In addition to powdered polyacrylamide, polyaluminum chloride and anionic polyacrylamide molded products, they are also widely used in organic wastewater treatment.
