Polyacrylamide for short PAM. Usually acrylamide monomer head - to - end bonding polymer, at room temperature as a hard glassy solid. As a result of different production methods, the product has white powder, translucent beads and flake, etc. Density 1.302g/cm3(23℃), vitrification temperature 153℃, softening temperature 210℃. It has good thermal stability. Soluble in water, aqueous solution is clear and transparent, its viscosity with the increase of polymer molecular weight obviously viscous, and with the change of polymer concentration in a logarithmic increase or decrease relationship. Except for a few solvents such as acetic acid, acrylic acid, chloroacetic acid, ethylene glycol, glycerin and formamide, it is generally insoluble in organic solvent Chemicalbook. By acrylamide monomer free radical polymerization, can be used in solution polymerization, inverse emulsion polymerization, suspension polymerization and solid polymerization several methods. The molecular weight of the product is controllable, water soluble and less residual monomer. Polyacrylamide is one of the most widely used water-soluble polymers with a large number of side amide groups on the main chain. Amides are chemically active and can form a series of derivatives with a variety of compounds. Polyacrylamide has a variety of functions such as flocculation, thickening, resistance reduction, bonding, stable colloid, film formation and scale inhibition, widely used in papermaking, mining, coal washing, metallurgy, oil mining and other industrial sectors, is an important chemical in water treatment.

Application

1.It is used as flocculant in water treatment industry. It is also used for the removal of non-dispersible low solid mud in petroleum geological drilling.

2.Sedimentation agent (sugar aid) in sugar industry; Film former.

3.Used as flocculant of water-based drilling fluid, it can improve rheological property of drilling fluid and reduce friction.

4.Used as soil modifier, flocculant, and can be used for textile sizing and paper reinforcement.

5.It can be used as an efficient flocculant in neutral and alkaline media and as a drilling mud additive.

6.Used as oil field mud treatment agent, sewage treatment agent, and used for textile sizing, paper reinforcement.

7.Polyacrylamide is an important water-soluble polymer, and has valuable properties such as flocculation, thickening, shear resistance, resistance reduction and dispersion. These properties vary with the Chemicalbook of the derivative ions. Therefore, it is widely used in oil extraction, mineral processing, coal washing, metallurgy, chemical industry, paper making, textile, sugar, medicine, environmental protection, building materials, agricultural production and other departments.

8.Widely used in petrochemical, metallurgy, coal, mineral processing and textile industries, Used as precipitation flocculant, oil field waterflooding thickener, drilling mud treatment agent, textile pulp Chemicalbook material, paper strengthening agent, fiber modifier, soil improver, soil stabilization agent, fiber paste, resin processing agent, synthetic resin coating, adhesive, dispersant, etc.
