High purity polyacrylamide is a linear polymer, its products are mainly divided into dry powder and colloid. According to its average molecular weight can be divided into low molecular weight (< 1 million), medium molecular weight (2 ~ 4 million) and high molecular weight (> :7 million) three major categories. According to its structure can be divided into non – ionic type, anionic type and cationic type. Water decomposition (HPAM), whose anion is mainly PAM. High purity polyacrylamide main chain has a large number of amide groups, has a high chemical activity, can be modified to prepare many high purity polyacrylamide derivatives. Products have been widely used in papermaking, mineral processing, oil production, metallurgy, building materials, sewage treatment and other industries.
High purity polyacrylamide should be moisture-proof and rainproof to avoid sun exposure. The high purity polyacrylamide produced by polyacrylamide manufacturers is white powder or small particles, the density is (23 degrees), the glass transition temperature is 188 degrees, softening temperature is nearly 210 degrees. Generally dry with a small amount of water, dry will quickly absorb water from the environment. The homopolymer isolated by freeze-drying is a white soft amorphous solid, but when it precipitates from the solution and dries, it is a glassy partially transparent solid. Fully dried high purity polyacrylamide pam is a fragile white solid. Commercial high purity polyacrylamide is usually dried under moderate conditions with a water content of 5% to 15%. The polymer film prepared by casting on a glass plate is a transparent, hard and brittle solid. High purity polyacrylamide is a linear polymer, its products are mainly divided into dry powder and colloid. According to its average molecular weight can be divided into three categories: low molecular weight (7 million).
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
