The scope of application of anionic polyacrylamide

1. Used in textile, printing and dyeing industries. Anionic polyacrylamide is used as a sizing agent and finishing agent for fabric treatment, and can form a soft, wrinkle-resistant, and mold-resistant protective layer. Utilizing its strong hygroscopicity, it can reduce the break rate when spinning spun yarn. Anionic polyacrylamide as a post-treatment agent can prevent static electricity and flame retardancy of the fabric. When used as printing and dyeing auxiliaries, anionic polyacrylamide can make the product have high adhesion fastness and vividness, and can also be used as a non-silicon polymer stabilizer for bleaching.

2. Mainly used as a flocculant: for suspended particles, coarse, high concentration, positively charged particles, neutral or alkaline sewage water pH value, because the anionic polyacrylamide molecular chain contains a certain amount of polar group energy Adsorbs the suspended solid particles in the water, and bridges the particles to form large flocs. Therefore, it accelerates the settling of particles in the suspension, and has a very obvious effect of accelerating the clarification of the solution and promoting filtration. This product is widely used in the treatment of chemical industrial wastewater and waste liquid, and municipal sewage treatment. Tap water industry, high turbidity water purification, sedimentation, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronics industry and other water treatment.

3. It is widely used in petroleum industry, oil production, drilling mud, waste mud treatment, preventing water channeling, reducing friction, improving oil recovery and tertiary oil recovery.

4. Used in the paper industry, one is to improve the retention rate of fillers and pigments. In order to reduce the loss of raw materials and environmental pollution; the second is to increase the strength of paper (including dry strength and wet strength). In addition, the use of PAM can also improve the tear resistance and porosity of paper to improve visual and printing performance. In food and tea wrapping paper.

5. Other industries, food industry, used for cane juice clarification and syrup phosphorus floatation extraction in the production of cane sugar and beet sugar. Enzyme preparation fermentation liquid flocculation clarification industry, also used for the recovery of feed protein, stable quality, good performance, the recovered protein powder has no adverse effect on the survival rate, weight gain and egg production of chickens, synthetic resin coating, civil engineering grouting material plugging Water, building materials industry, improvement of cement quality, construction industry adhesives, joint repair and water blocking agent, soil improvement, electroplating industry, printing and dyeing industry, etc.
