Anion polyacrylamide to distinguish the use of anions

The main uses of cationic polyacrylamide differ from anions as inclined plate sedimentation tank deposition and cations as sludge treatment.

Now let’s introduce the main uses of anionic polyacrylamide:

(1) The key is coagulant: because the anionic polyacrylamide molecular structure chain has a certain amount of spin based energy, adsorption floating in water solid particles, so that the railway bridge between particles produced large inclined plate sedimentation tank. Therefore, it accelerates the foundation settlement of particles in the mixed liquid, accelerates the reaction of aqueous solution obviously, and promotes the practical effects such as filtration. This product is widely used in chemical waste water, waste water solution, municipal engineering waste water treatment. Drinking water industrial production, high turbidity coarse salt purification, clearing, coal selection, mining plant, metallurgical industry, iron and steel industry, zinc, aluminum manufacturing, electronics industry and other sewage treatment.

(2) Widely used in petrochemical industry, oil fields, drilling fluid, waste sludge treatment, water avoidance, reduce friction resistance, improve the degree of oil recovery, tertiary oil recovery.

(3) Used for textile desizing agent, pulp characteristics are stable, less falling pulp, textile broken rate is low, nylon cloth smooth.

(4) Used in paper industry, one is to improve the retention rate of filler, color paste, etc. In order to reduce the outflow of raw materials and environmental pollution to the natural environment, the second is to improve the compressive strength of printing paper (including dry compressive strength and wet compressive strength). In addition, the application of anionic polyacrylamide can also improve the tear resistance and porous structure of paper, visual effects and packaging printing characteristics, also used in food and tea packaging.
