High purity polyacrylamide is a linear polymer, easily soluble in water, generally organic solvents, its aqueous solution is almost transparent viscous liquid, is a non-dangerous product. The density is (23 degrees), the glass transition temperature is 188 degrees, the softening temperature is close to 210 degrees. Generally dry with a small amount of water, dry quickly absorb water from the environment. The homopolymer separated by freeze-drying is a white soft amorphous solid, but after precipitation from solution and drying, it is a glassy partially transparent solid. Fully dried high purity polyacrylamide is a fragile white solid. Commercial high purity polyacrylamide is usually dried under mild conditions. 12 million anionic polyacrylamide models complete (2022 update). Polyacrylamide can be divided into non-ionic type according to its structure. Few people ask about the degree of hydrolysis, which is also an important technical index to judge apam. The degree of hydrolysis of high purity polyacrylamide is degree, which refers to the percentage of the amide group in the polyacrylamide molecule converted to carboxyl group during the hydrolysis process. Polyacrylamide is a non-ionic polyacrylamide hydrolyzed under basic conditions (generally with sodium hydroxide and other alkali oxidation).
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
