Application of anionic polyacrylamide (AN923) in mineral processing

 

The company produces anionic polyacrylamide according to different uses, divided into two production processes, a homopolymerization, a copolymerization; Anionic polyacrylamide is white granule/powder, with flocculation, thickening, shear resistance and other properties, easily soluble in water, almost insoluble in organic solvents, widely used in sewage and drinking water treatment, paper making, oil mining, coal washing, construction, textile and other industries. This product has passed ISO9001 quality certification.

 

Industrial wastewater treatment: for suspended particles, coarse, high concentration, particles with positive charge, PH value of water neutral or alkaline sewage, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, the best effect.

 

Drinking water treatment: generally choose high molecular weight is appropriate. The water source of many water plants in Our country comes from rivers. The sediment and mineral content are high and muddy. Although filtered by precipitation, it still cannot meet the requirements and needs to add flocculant. In the past, inorganic flocculant was mostly used in waterworks, but it was easy to increase secondary sludge due to large dosage. Anionic polyacrylamide is now used as flocculant, the dosage is 1/50 of inorganic flocculant, but the effect is several times of inorganic flocculant. The inorganic flocculant and cationic polyacrylamide produced by our company can be used with a better effect for the river water with serious organic pollution.

 

Amylase factory and distillery loss of starch wine tank recovery: now many amylase factory wastewater contains a lot of starch, adding anionic polyacrylamide, so that starch particles flocculation precipitation, and then the sediment by the press filter into cake, can be used as feed. Distillery tank can also use my company's production of cationic polyacrylamide, pressure filtration recovery.

 

Paper auxiliaries: clarification of burning lye in paper industry; Fiber dispersant, can improve beating degree, filler retention aid, paper strengthening agent, can be used to improve water filtration rate and water recovery.

 

Oil field auxiliary agent: water plugging agent for profile control and water plugging in oil field, and oil displacement agent for tertiary oil recovery.

 

Packing, storage and matters needing attention: 25Kg plastic lining woven bag or paper-plastic composite bag, or according to user's requirements. When storing and transporting, pay attention to prevent heat and moisture to prevent package damage. Dry powder products will absorb moisture and agglomerate when exposed for a long time. Stacking layers shall not exceed 20 layers. Effective storage life is 2 years.
