Is polyacrylamide cationic or nonionic?

Polyacrylamide cationic Pam is suitable for suspending materials with negative charge and organic matter. Polyacrylamide nonionic Pam is suitable for separation of suspended solids in organic and inorganic mixtures, and the solution is acidic or neutral.

What are the different types of polyacrylamide (PAM)?

According to its ionic properties, PAM is divided into three main types: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) and nonionic (Nonionic PAM, NPAM). These three types have significant differences in structure, function and application. 1. Cationic polyacrylamide (Cationic PAM, CPAM) Structure and properties:

What is the difference between polyacrylamide anion and cationic Pam?

polyacrylamide anion type Pam is suitable for high concentrations of positively charged inorganic suspensions, as well as coarse suspended particles (0.01-1mm), with a ph value of neutral or alkaline solution. Polyacrylamide cationic Pam is suitable for suspending materials with negative charge and organic matter.

What is the effect of cationic polyacrylamide?

The effect of cationic polyacrylamide is several times or tens of times higher than that of anionic, non-ionic polyacrylamide or inorganic salt, because this kind of wastewater generally has negative charge. 2. Application of anionic polyacrylamide (1). Industrial wastewater treatment

What is anionic polyacrylamide used for?

Anionic polyacrylamide is suitable for treating positively charged particles such as suspended solids and colloids in wastewater. Compared to cationic PAM, anionic polyacrylamide is usually less expensive and is suitable for large-scale use.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (Anionic PAM, APAM) Structure and properties: Anionic PAM is a water-soluble polymer. By introducing these anionic groups on the polymer backbone, APAM can react with positively charged substances. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewaters.
