rylamide from couies and regi*** such as Taiwan and Japan. 2.溶解粉状聚合物的水应是干净水(如自来水),不能是污水,常温的水即可,一般不需要加温。水温低于5 OC时溶解很慢。水温提高溶解速度加快,但40OC以上会使聚合物加快降解,影响使用效果。一般自来水都适合于配制聚合物溶液,但强酸、强碱、高含盐的水不适于用来配制。Solid polyacrylamide is a kind of white or yellowish particle or powder with molecular weight between 4 million and 20 million. Solid products have white or yellowish appearance. Polyacrylamide flocculant is a kind of high molecular organic compound. Its molecular werated c***truction of water pollution control project in China, the c***umption of pry imports will be reduced by polyacrylamide. In 2010, the import of Polyacrylamide in China will be about 20 thousand t***. The development of Polyacrylamide in the petroleum industry is focusing on the development of super high molecular weithe production of crude oil
