Polyacrylamide and its wide application.

original title: Polyacrylamide and its wide applicationPolyacrylamide is a line polymer, the product is mainly divided into dry powder and collate two forms. According to its average molecular weight can be divided into low molecular weight (1 million), medium molecular weight (2 to 4 million) and polymer mass (7 million) three categories. According to its structure can be divided into non-ion type, anion type and cation type. The anion type is mostly PAM's water disintegration (HPAM). Polyacrylamide main chain with a large number of alamy base, chemical activity is very high, can be modified to make many polyacrylamide derivatives, products have been widely used in papermaking, mineral processing, oil extraction, metallurgy, building materials, sewage treatment and other industries. Polyacrylamide, as a lubricant, suspension agent, clay stabilizer, oil repellent, dewatering agent and thickener, is widely used in drilling, acidification, fracturing, water blocking, solidification and secondary oil extraction, and triple oil extraction. Application, is an extremely important oil field chemicalpolyacrylamide (PAM) is a general acrylamide polymer or polymer with other monomers, is one of the most widely used varieties in water-soluble polymers. Because polyacrylamide structure unit contains acetaminophen, easy to form hydrogen bonds, so that it has good water solubility and high chemical activity, easy to obtain a branch chain or mesh structure through branching or cross-linking a variety of modifiers, in oil exploration, water treatment, textile, paper, mineral processing, medicine, agriculture and other industries have a wide range of applications, there is a "hundred industry aids" said. The main applications abroad are water treatment, papermaking, mining, metallurgy, etc.. Responsible editor:
