Introduction to the scope of action of polyacrylamide

1, water treatment field

Water treatment includes raw water treatment, sewage treatment and industrial water treatment. In the raw water treatment and activated carbon, etc., can be used for the coagulation and clarification of suspended particles in domestic water. By replacing inorganic flocculants with organic flocculants such as acrylamide, the water purification capacity can be increased by more than 20% even if the settling tank is not modified;

In sewage treatment, the use of polyacrylamide can increase the use of water reuse cycle, can also be used as sludge dewatering; industrial water treatment as an important formulation of pharmaceuticals. Polyacrylamide in foreign applications is the largest field of water treatment, the domestic application in this field is being promoted.

2, the application of oil recovery

Polyacrylamide is a kind of multifunctional oilfield chemical treatment agent, which is widely used in drilling, cementing, well completion, well repair, fracturing, acidizing, water injection, water plugging and profiling, three oil recovery operations, especially in the field of drilling, water plugging and profiling and three oil recovery. Polyacrylamide aqueous solution has high viscosity, good thickening, flocculation and rheological adjustment, used as oil repellent and drilling mud regulator in oil extraction.

3、Paper making field

Polyacrylamide in the field of papermaking is widely used as retention aid, filtration aid, homogenizer, etc. in order to improve the quality of paper, slurry dewatering performance, retention of fine fibers and fillers, reduce the consumption of raw materials and environmental pollution, used as a dispersant to improve the uniformity of paper.
