Polyacrylamide referred to as "PAM, and a very short moment (HPAM) cation ions (CPAM) and nonionic (NPAM) is a kind of linear high polymer, is a water-soluble polymer compounds, one of the most widely used in varieties of polyacrylamide and its derivatives can be used as effective flocculant, thickening agents, paper strengthening agent and fluid drag reduction agent, etc., are widely used in water treatment, paper making, petroleum, coal, mining and metallurgy, geology, light textile, construction and other industrial sectors.

PAM PAM consists of acrylamide (AM) monomers by free radical polymerization of water soluble linear polymers, has good flocculation sex, can reduce the friction resistance between liquid, by ion characteristic points can be divided into non-ionic and anionic, cationic and amphoteric four types. Polyacrylamide (PAM) does not dissolve in most organic solvents, such as methanol, ethanol, acetone, ethyl ether, fatty hydrocarbon and aromatic hydrocarbon, except a few polar organic solvents, such as acetic acid, acrylic acid, chloroacetic acid, ethylene glycol, oil, melting urea and formamide. But the solubility of organic solvent is limited, often need to be heated, otherwise no application value.
Polyacrylamide mesh: the mesh refers to the granularity of the material or thickness, item number is the number of squares on the per unit area. General definition refers to the 1 inch by 1 inch area has how many mesh count, the number of mesh screen. Such as 600 mesh is 600 per square inch square mesh, mesh of polyacrylamide 20 mesh to 80 mesh, which is between 0.85 mm to 0.2 mm, this is granular polyacrylamide mesh size, powdered polyacrylamide mesh size can be controlled at about 100 mesh, mesh of polyacrylamide is more easily dissolved, the greater the polyacrylamide mesh size alone is unable to measure the quality of the product!
Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation sex, can reduce the friction resistance between liquid.
Polyacrylamide (PAM) along with our country industry running the expansion of the market demand and export growth, polyacrylamide (PAM) industry in China run usher in a new development opportunity.
Polyacrylamide is white powder or granules, density of 1.32 g/cm3 (23 degrees), glass transition temperature is 188 degrees, the softening temperature to 210 degrees, a general method contains a small amount of water when dry, dries quickly again suck up moisture from the environment, with the separation of freeze drying homopolymer is white fluffy non-crystalline solid, but when after precipitated from the solution and dry is vitreous partially transparent solid, completely dry PAM PAM is brittle solid white, dry goods polyacrylamide is usually under the condition of moderate dry, average moisture content of five percent to fifteen percent, casting preparation of polymer film on glass, are transparent, hard, brittle solid
