Anionic Polyacrylamide The Performance
Jun 26, 2017

What are the requirements for anionic polyacrylamide as a water treatment flocculant? Anionic polyacrylamide is a commonly used water treatment agent, Anionic Polyacrylamide due to its special properties, water treatment effect is much better than other products. PAM is used for flocculation, which is related to the surface properties of the floc, especially the potential, viscosity, turbidity and the pH value of the suspension. Anionic Polyacrylamide The motive potential of the particle surface is the reason for the addition of the surface charge. Can make the potential lower and cohesion. What are the requirements for anionic polyacrylamide as a water treatment flocculant?

The requirements for anionic polyacrylamide as a flocculant are:

1, good water solubility, dubbed glue, the static 24 hours does not produce the density difference;

2, glue the suspension of strong, can suspend iron filings, cuttings and other detritus;

3, glue rheological properties, shear dilution strong, low friction;

4, anti-formation water calcium ions, Anionic Polyacrylamide magnesium ions, iron ions and other salt pollution;

5, anti-temperature 90--100 ℃.

The method of compound flooding has the dual effect of improving the micro-oil displacement efficiency and flow control by using the super-addition of alkali and surfactant in reducing the interfacial tension, so it has developed rapidly in recent years and got a certain scale in the mine application. However, between the surfactant and the polymer in the system, a surfactant-polymer aggregate (complex) is formed. Therefore, Anionic Polyacrylamide it is important to understand the interaction between the polymer and the surfactant to understand the characteristics of the composite flooding system. There are more reports about the interaction between surfactants and polymers, and Myers reports the interaction of surfactants with nonionic and ionic polymers and analyzes the mechanism of formation. However, two kinds of anionic surfactants such as sodium laurate (C11H23COONa) and sodium dodecylsulfonate (C12AS) were studied by the change of the viscosity of the system, because the material had a great influence on the macroscopic properties of aggregates. Acrylamide (PAM) solution characteristics.

Anionic polyacrylamide is mainly used as a flocculant: for suspended particles, Anionic Polyacrylamide coarse, high concentration, the particles with positive charge, water PH value of neutral or alkaline sewage, because the anionic polyacrylamide molecular chain contains a certain amount of The base can adsorb the solid particles suspended in the water, so that the bridge between the particles to form a large floc. So it accelerates the deposition of particles in the suspension, there is a very clear way to speed up the clarification of the solution, resulting in filtration and other effects. The product is widely used in chemical industry wastewater, Anionic Polyacrylamide waste treatment, municipal sewage treatment. Water industry, high-turbidity water purification, Shen Qing, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, Anionic Polyacrylamide aluminum processing industry, electronics industry and other water treatment.
