Does anionic polyacrylamide increase stability of dispersed solid particles?

Generally, the anionic polyacrylamide addition improves stability of the dispersed solid particles (at fixed pH and temperature, the decrease of TSI values for the system containing PAM in relation to that without polymer is observed). Table 2. Stability coefficient TSI for all examined systems, C PAM = 100 ppm

What is anionic polyacrylamide (Apam)?

1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [, , ].

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.

Why is poly(acrylamide) a good soluble polymer?

The thermal stability of poly (acrylamide) solutions are generally higher than most other water-soluble polymers; however, the high molecular weight species, like their POE equivalents, have very high extensional viscosities, favor-able for good drag reduction behavior, but this also reflects on their rapid degradation under mechanical deformation.

How can a water soluble anionic polyacrylamide improve the characteristics of loess?

The typical characteristics of loess, such as macropores, weak cementation, and strong collapsibility, can adversely affect the stability of building foundations, transportation infrastructure, and other geotechnical systems. To address this problem, a water-soluble anionic polyacrylamide (APAM) was used to improve the characteristics of loess.
