In the hot and humid summer months, many manufacturers are concerned that high temperatures may affect polyacrylamide and even wastewater treatment. The viscosity of polyacrylamide solutions does have a certain relationship with temperature.
It is well known that before using polyacrylamide to treat wastewater, it needs to be dissolved first and then added to the wastewater after the concentration ratio reaches an appropriate level. If there is a problem with the viscosity of the polyacrylamide dissolved during this process, it will result in a discount for the utility. The viscosity of polyacrylamide is affected by temperature, mechanical action, storage time, impurities and light. If you want to keep the viscosity within an appropriate range, you need to pay attention to these influencing factors.
When configured as a solution, polyacrylamide is more sensitive to its solid form. If the temperature of the prepared solution exceeds the normal level, as the temperature continues to rise, the degradation accelerates, the molecular weight decreases, and the viscosity will also be affected. The mechanical action here refers to the stirring speed of the polyacrylamide solution. Stirring too fast will affect the molecular chain of polyacrylamide, reduce the viscosity of the solution, and affect the efficiency.
After polyacrylamide is configured as a solution, the storage time is greatly shortened. As the storage time continues to increase, the viscosity of the polyacrylamide solution will also decrease after a certain period of time. Light not only increases the temperature, but also accelerates the degradation of the polyacrylamide solution under direct ultraviolet radiation, thereby reducing the molecular weight and affecting the viscosity.
In order to maintain the flocculation effect of polyacrylamide solution in summer, the principle of ready availability should be followed as much as possible. And pay more attention to these factors that may affect viscosity to avoid reduced viscosity and reduced efficiency.
