Reasons for Decreasing Flocculation Effect of Non-ionic Polyacrylamide

Non-ionic polyacrylamide is a very common sewage treatment material, it can be said that it has a huge impact on the environmental protection industry. The industry that applies to it is also very extensive, and it can be seen everywhere even in life. However, customers encountered problems in the use of non-ionic polyacrylamide reagents in the application process often appear in the state of shear force reduction and flocculation effect reduction, what is the cause of this?

First of all, we should consider the storage time of non-ionic polyacrylamide. The more hydrolysis the reagent, the lower the viscosity and the worse the flocculation effect. Stirring can increase the water-soluble speed of dry polyacrylamide powder, high stirring speed, and cut the molecular chain of polyacrylamide. It is suggested that the stirring speed should be controlled at 60 rpm on-line. It is not possible to use high-strength stirring equipment and fast conveying equipment. Secondly, it can not be irradiated by sunlight for a long time, because the light will increase the temperature, make polyacrylamide dissolve and hydrolyze, and ultraviolet direct irradiation will make water dissolve quickly.
