Introduction of polyacrylamide Polyacrylamide is water-soluble polymer, appearance is white or light yellow toner particles, easy bibulous, long-term thermal decomposition, decomposition temperature above 200 , under anaerobic conditions, 210 carbonized to black powder. Insoluble in most organic solvents, has good flocculation sex, can reduce the friction resistance between liquid, ion characteristics can be divided into non-ionic and anionic, cationic and amphoteric four types. Polyacrylamide is a kind of abnormal function of the fine water disposal reagents, and is non-toxic, does not pose too much persecution to water quality. Polyacrylamide flocculation treatment of waste water, cover an area of an area small, less investment, strong adaptability, a brief, high processing efficiency, can control the space is large, etc. PH value is too low, acid easily provoked explosion together, constitute a crosslinking shape insolubles, spending anionic polyacrylamide and lower part; With the increase of PH value, weak alkaline acid reaction solution increased, spending amount of polyacrylamide part gradually cut, good ablation. Polyacrylamide is a kind of efficient additives, is a good assistant, we purify environment polyacrylamide is widely used as flocculant, suspended in liquid has a good job. Many enterprises in order to environmental protection is done using polyacrylamide flocculant, more common is the water purification, textile, coal, paper and other industries. Polyacrylamide is mainly used as pulp fiber and additive of adhesives, polyacrylamide for waste water treatment at the same time. Polyacrylamide has been widely used in water treatment, paper, glue, urban sewage, oil, coal, mining and metallurgy, geology, light textile, construction and other industrial sectors. Especially the flocculation performance application in all walks of life are essential.
