Can heteroscedasticity (易 分散 性) polymer composition of the charter

摘要

An easily-dispersible compn. having a high degree of granularity and free-fluidity comprises, a powder of water-soluble polymer having flocculating ability, a hydrated sodium sulphate, and an opt. hydrated magnesium sulphate and/or hydroscopic agent. The water soluble polymer is a nonionic polyacrylamide, an anionic partially hydrolysed polyacrylamide or sodium carboxymethyl cellulose, or cationic aminoethyl polyacrylate, or cation modified polyacrylamide. The hydrated sodium sulphate is the hydrated and/or decahydrate.
