Anionic Polyacrylamide(APAM)
Anionic polyacrylamide (APAM) series products are water-soluble linear polymers synthesized under high degree polymerization, easily soluble in water, almost insoluble in benzene, ether, aliphatics, acetone and other common organics solvents. At the meantime, APAM series product also have valuable properties like flocculation, thickening, shear property, drag-reduction and dispersibility. Thus widely used in oil recovery, mineral processing, coal washing, metallurgy, chemicals, paper, textile, sugar, medicine, environmental protection, building materials, agriculture and other industries.

Main usage
Displacement agent for Tertiary recovery of oilfields: It can adjust the rheology of water injection, increase the viscosity of displacing liquid, improve the spreading efficiency of liquid displacement, bring down the water permeability in strata and keep water and oil to flow at a constant speed. It is mainly used in tertiary recovery of oilfields. Injection of each ton of polyacrylamide products can help to gather 100-150 tons extra crude oil.
Drilling mud material: Used as drilling mud additives in oil field exploration and development and geology, water conservancy and coal exploration. It can prolong the bit’s life, raise the drilling rate and drilling footage, reduce the time of exchanging drills. It has obvious effect in avoiding well collapse. It can also be used as oil field fracturing fluid and profiling water blocking agent.
Industrial wastewater treatment: Especially for the treatment of wastewater containing suspended particles, coarse and high concentrated particles with positive charges and water’s PH value is neutral or alkaline. Most effective for wastewater treatment of Iron and steel plant, electroplate factory, metallurgy and coal washing.
Drinking water treatment: Many water plants in China come from river water, which contains large sum of sediment and mineral, very turbid. After precipitation and filtration, it still can not meet the requirements. Flocculant is needed. Water plants used to use inorganic flocculants, but large additive amount is required which caused the increase of sludge volume, not effective. Use anionic polyacylamide flocculants, with 1/50 additve amount that of inorganic flocculants, several times and even dozens of times effectiveness obtained than that of inorganic flocculants. For those organic polluted river water, better effectiveness can be achieved while mixed used together with cationic polyacrylamide.
Papermaking additives: Can be used for caustic soda’s clarification. Used as retention aid, filter aid, reinforcing agent for wet and dry paper.
Clarifying agent in sugar refining industry;
Additives and adhesives in aquatic product feedstuff.
Packaging and Storage
Packaging: 25kg paper-plastic bag packing or according to customer’s requires. Dry powder products easily absorb moisture and cake under prolonged exposure. To be stored in cool, dry and well ventilated place.
