What is anionic polyacrylamide used for?

Anionic polyacrylamide can be used as a cytoplasm additive in the paper industry with better retention and drainage effect. It has a particularly dispersing effect for long-fiber pulp when its molecular weight is greater than 3.5 million. In addition, it can also be used as a water treatment agent.

What is polyacrylamide polymer?

Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.

What is the pH range of polyacrylamide?

In the pH range of 3 to 9, it can maintain a good degree of stability; at high pH, the viscosity will be increased gradually. Miscibility: in generally used concentration, polyacrylamide has miscibility with most water-soluble natural or synthetic resins, latex systems, and most of the salts.

Is polyacrylamide soluble in water?

Figure 1 The synthetic route of polyacrylamide. Polyacrylamide is relatively stable to heat with its solid only being softened at 220~230 °C and its solution subjecting to significant degradation only at above 110 °C. Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water.

Is polyacrylamide toxic to humans?

Toxicity: Polyacrylamide itself is non-toxic, but if it contains polymerized monomers (a double bond), it would be toxic to humans. For this reason, upon the completion of its preparation, a certain amount of sodium bicarbonate should be added to remove residual monomers. The above information is edited by the chemicalbook of Dai Xiongfeng.

How to make polyacrylamide solution?

Solution should be made up at 0.1-0.3% solid. Make-up water temerature should be between 10 o C to 40 o C for optimum product performance. Following dispersion into agitated water, stirring should be continue for about an hour. The liquid polyacrylamide are stable for one week. 5. Company Exhibition
