Polyacrylamide products are mainly divided into anionic, cationic, and nonionic models. The properties of each different model of polyacrylamide are different, and the industrial applications they function in are also various. Among them, the industrial application of cationic polyacrylamide has the highest polyacrylamide cost and cost, so what are the broad fields of action its product properties have.

Composite insulators and surge arresters are important components of power systems, and are widely used with the popularization and development of power systems. In recent years, the types and performance of insulators and lightning arresters are used for protection against have been continuously improved, especially the widespread application of composite insulating materials, which has gradually extended from power systems to other fields such as rail transit.
