Water Treatment Field
Polyacrylamide has a good property of flocculation in water treatment. It could help separate the solid and liquid quickly in water and accelerate the sedimentation of solids. The quality of water will improve after polyacrylamide treatment.
Mineral Field
The flotation method is normally used in mineral processing. The mineral attaches to the bubbles and comes up to the pulp surface. Polyacrylamide could be added to the ore pulp to increase the adhesion and absorption between minerals and bubbles. This could help increase the recovery rate of minerals. Most minerals need dewatering during mineral processing.
Paper Industry
The high speed of paper machines requires the support of retention and drainage technology. Polyacrylamide could improve the retention rate of fiber and filler, and improve the drainability of paper stock. Polyacrylamide could also act as a sizing agent during paper making. It could improve the water proof feature of paper to increase persistence and shelf life. As it could form a dense film with fiber, the film has fine water proof features and prevents the water seep into the paper. For cationic polyacrylamide with low molecular weight, it could act as a dispersant to improve the uniformity of paper.
Oilfield Field
Polymer flooding technology needs high molecular weight polyacrylamide to increase the viscosity of infusing water. The oil-gas mobility ratio is improved. Then the water will replace the crude oil and drive it out, which improves the oil yield. In the fracturing process, polyacrylamide is added to the fracturing fluid due to its high viscosity, low frictional resistance, good sand-carrying ability, easy to prepare and low cost.
