How Much Do You Know About CationicPolyacrylamide?

Polyacrylamide, also known as PAM, is not well understood by many people, who only know it as an efficient water purificationagent. In fact, the uses of polyacrylamide are very numerous.

Polyacrylamide is known as the "universal auxiliary", demonstrating its utility in various industries. Polyacrylamide (PAM) is mainly divided into anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, and amphoteric poyacrylamide.

Diferent types of polyacrylamide have different functions. Anionic polyacrylamide is mainly used for wastewater sedimentation, cationic is used for sludge dewatering andsludge cake pressing, and non-ionic is used for flocculation and sedimentation of complex water bodies.

Friends who often use polyacrylamide and other industrial additives know that cationic polyacrylamide is relatively moreexpensive than other additives, and the larger the molecular weigh, the more expensive the price. If you want to save costs, you need to pay attention to the storage of this agent. Otherwise, if any problems occur, it could cause severe losses. This article wilintroduce relevant information about cationic polyacrylamide

Cationic polyacrylamide is popular because of its unique structure. Compared with other similar functioning agents, cationic polyacrylamide has higher adsorption capacity and better removal of organic water effects. It can better meet various needs forindustrial wastewater treatment and decolorization.

Cationic polyacrylamide is mostly in powder form, and the emulsion products. Generally,the concentration of the solution is 0.1%. The types of anionic polymer solutions should not exceed one week, and cationic polymer solutions should not exceed one day. However, 3%-5% solutions should not be directly used for wastewater treatmentand need to be diluted.

The shelf life of cationic polyacrylamide powdr is 2 years, but the emulsion should be less than 12months. Beyond this period, it is usually considered expiredand may face the possibility of ineffectiveness. Of course, this is not absolute. For example, cationic polyacrylamide storage conditions will have a significant impact on its shelf life.

Simply put, if cationic polyacrylamide is stored in a ventilated, dry, and cool place, its shelflife can be extended. Conversely, ifstored in a high-temperature, humid environment the shelf life of cationic polyacrylamide will be shortened.
