Get PriceWhich is better cationic or anionic polyacrylamide?
Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.
What is anionic polyacrylamide (Apam)?
Anionic polyacrylamide (APAM) is its negative charge, which makes it highly effective in a wide range of applications. Anionic polyacrylamide (APAM) is highly water-soluble, which means that it can be easily dissolved in water and other aqueous solutions. This makes it easy to use in various applications, such as in the treatment of wastewater.
Is polyacrylamide ionic or cationic?
Due to its excellent flocculation, thickening, and enhancing properties, polyacrylamide is widely used in various industrial fields such as water treatment, paper making, petroleum, coal, and mining metallurgy. Based on its ionic characteristics, polyacrylamide is mainly divided into three categories: anionic, cationic, and non-ionic.
What are the different types of polyacrylamide?
Based on its ionic characteristics, polyacrylamide is mainly divided into three categories: anionic, cationic, and non-ionic. Amphoteric polyacrylamide is also used in specific fields. This article will delve into the differences between anionic polyacrylamide and cationic polyacrylamide in application.
What is nonionic polyacrylamide?
3. Nonionic Polyacrylamide (Nonionic PAM, NPAM) Structure and Properties: Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain.
Why is anionic polyacrylamide important in water treatment?
These groups can neutralize charges with positively charged particles in water and form larger flocs through bridging, thus accelerating the sedimentation of particles in the suspension. Anionic polyacrylamide plays a significant role in water treatment in the following aspects:
