25 KG/BAG PAM Used in Water Treament, Oil Production, Paper Making and Medicine
Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. It is a hard glassy solid at room temperature. Its products include glue, latex, white powder, translucent beads and flakes. It has good thermal stability. It can be dissolved in water in any proportion, and its aqueous solution is a uniform transparent liquid. After long-term storage, the viscosity of the solution will decrease due to the slow degradation of the polymer, especially when the storage and transportation conditions are poor. [1] Polyacrylamide is widely used as a lubricant, suspending agent, clay stabilizer, oil displacement agent, fluid loss reducer and thickener in drilling, acidizing, fracturing, water plugging, cementing, secondary oil recovery and tertiary oil recovery. It is an extremely important oilfield chemical.

1. In water treatment
The main functions of polyacrylamide in water treatment:
(1) Reduce the amount of flocculants used. Under the premise of achieving the same water quality, polyacrylamide can be used as a coagulant in combination with other flocculants to greatly reduce the amount of flocculants used;
(2) Improve water quality. In drinking water treatment and industrial wastewater treatment, polyacrylamide can be used in combination with inorganic flocculants to significantly improve water quality;
(3) Improve floc strength and sedimentation rate. The flocs formed by polyacrylamide have high strength and good sedimentation performance, thereby increasing the solid-liquid separation rate and facilitating sludge dewatering;
(4) Anti-corrosion and anti-scaling of circulating cooling systems. The use of polyacrylamide can greatly reduce the amount of inorganic flocculants used, thereby avoiding the deposition of inorganic substances on the surface of the equipment and slowing down the corrosion and scaling of the equipment.
2. In oil production
Polyacrylamide is a multifunctional oilfield chemical treatment agent, which is widely used in the drilling, cementing, completion, workover, fracturing, acidizing, water injection, water plugging and profile control, and tertiary oil recovery operations of oil production, especially in the fields of drilling, water plugging and profile control, and tertiary oil recovery. The aqueous solution of polyacrylamide has a high viscosity, good thickening, flocculation and rheological adjustment effects, and is used as an oil displacement agent and drilling mud conditioner in oil production.
3. Paper making
Polyacrylamide is mainly used in two aspects in the papermaking industry. One is to increase the retention rate of fillers, pigments, etc. to reduce the loss of raw materials and pollution to the environment; the other is to improve the strength of paper. Adding polyacrylamide to paper stock can increase the retention rate of fine fibers and filler particles on the net and accelerate the dehydration of paper stock.
4. In medicine
Polyacrylamide gel can be used as a non-prothrombin granulating agent, surgical, contact lens raw material, microcapsule outer coating material, and used to make high-quality hemostatic plugs, sanitary napkins for women and diapers for children, etc.
