Anionic Polyacrylamide

Anionic Polyacrylamide

It should be used for flocculation and sedimentation of various industrial wastewater, sedimentation and clarification, such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, sludge dewatering, etc.



Anionic polyacrylamide (APAM) is a copolymer of acrylamide and acrylate. It is a water-soluble linear polymer flocculant. It promotes particle flocculation by neutralizing the charge on the surface of suspended particles in water, thereby destabilizing and destabilizing particles in water. The latter particles are adsorbed to each other under the bridging effect of polymer active genes to form larger flocs.
1. The flocs are compact and the dosage is small.
2. The treated water has high clarity.
3. The PH value has a wide range of application (5-14).
4. Good filtration and dewatering properties improve the dewatering effect of sludge.
5. Good compatibility with inorganic coagulants.
3. Product use:
1. Anionic polyacrylamide is used in textile printing and dyeing industry. Polyacrylamide acts as a sizing finish for fabric treatments, as well as creating a soft, wrinkle- and mildew-resistant protective layer. Taking advantage of its strong hygroscopicity, the breakage rate during spinning can be reduced.
Polyacrylamide as a post-treatment agent can prevent static electricity and flame retardancy of the fabric. When used as printing and dyeing auxiliaries, polyacrylamide can make the product have high adhesion fastness and high brightness, and can also be used as a non-silicon polymer stabilizer for bleaching.
2. When anionic polyacrylamide is mainly used as a flocculant, for suspended particles, the particles are relatively coarse, high in concentration, and the particles are positively charged, and the Ph of the water is neutral or alkaline sewage. The mass base can absorb the solid particles suspended in the water, so that the particles can bridge to form large flocs. Therefore, it accelerates the sedimentation of the particles in the suspension, significantly accelerates the clarification of the solution, and promotes filtration and other effects. This product is widely used in chemical industry wastewater, waste liquid treatment, municipal sewage treatment. Water treatment in tap water industry, high turbidity water purification, sedimentation, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronics industry, etc.
3. Anionic polyacrylamide is widely used in the petroleum industry, oil production, drilling mud, waste mud treatment, preventing water channeling, reducing friction, enhancing oil recovery, and tertiary oil recovery.
4. For the paper industry, anionic polyacrylamide can firstly improve the retention rate of fillers, pigments, etc., thereby reducing the loss of raw materials and pollution to the environment; secondly, improve the strength of paper (dry strength and wet strength), in addition, use anionic polyacrylamide. It can also increase paper tear resistance and porosity, thereby improving visual and printing properties, and is also used in food and tea wrapping paper.
5. Anionic polyacrylamide is used in other industries, food industry, for cane juice clarification and syrup phosphorus float extraction in the production of cane sugar and beet sugar. Enzyme preparation fermentation broth flocculation and clarification industry, can also be used for the recovery of feed protein, with stable quality and good performance. The recovered protein powder has no adverse effect on the survival rate, weight gain and egg production of chickens. Synthetic resin coatings, civil grouting materials block Water, building materials industry, cement quality improvement, construction adhesive, caulking repair and water blocking agent, soil improvement, electroplating industry, printing and dyeing industry, etc.
