3. Application
Anionic Polyacrylamide:
Anionic PAM is mainly used in minerals selection, metallurgy, coal washing, food, steel, spinning and papermaking industry which involves separation of solid-liquid and waste water treatment. Anionic PAM can also be used for oil well and oil extraction in oil industry, and retention aids and intensifier in papermaking industry.
Cationic Polyacrylamide:
Cationic polyacrylamide is mainly used as flocculants and dewatering reagents for industry waste water and sewage; retention aids and intensifier in paper making industry; waste water treatment in pharmaceutical, leather making, printing and dyeing industry waste water treatment, and organizer in textile industry.
Non-ionic Polyacrylamide:
Nonionic polyacrylamide is mainly used as flocculants with high selectivity in oil well fluid,and acidic waste water treatment.
Amphoteric Polyacrylamide:
Amphoteric polyacrylamide is mainly used high difficult waste water treatment or sludge dewatering reagents in oil refining and chemical industry or papermaking industry.
4. Packing and storage

聚丙烯酰胺
聚丙烯酰胺是一种线型高分子聚合物，化学式为(C3H5NO)n。在常温下为坚硬的玻璃态固体。产品有胶液、胶乳和白色粉粒、半透明珠粒和薄片等。热稳定性良好。能以任意比例溶于水，水溶液为均匀透明的液体。长期存放后会因聚合物缓慢的降解而使溶液粘度下降，特别是在贮运条件较差时更为明显。聚丙烯酰胺作为润滑剂、悬浮剂、粘土稳定剂、驱油剂、降失水剂和增稠剂，在钻井、酸化、压裂、堵水、固井及二次采油、三次采油中得到了广泛应用，是一种极为重要的油田化学品。
