Anionic polyacrylamide with super high relative molecule weight was prepared from polyacrylamide by hydrolysis. Main factors, such as hydrolysis temperature, time and concentration affecting molecule weight of anionic polyacrylamide have been studied. The optimum hydrolysis conditions were determined by orthogonal test design.
Product characteristics and main usages:
For the sewage of a positive charge with suspended particulates and its PH value is neutral or alkaline, APAM plays a role of electrical neutralization with the suspended particles and makes a bridge to form large flocs among the particulates. It is widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic industry. It is also used in oil industry to enhance oil recovery which is widely used. In addition, it can be used as paper additives and textile pulp agent.Product characteristics and main usages:
