What Effect Does Water Temperature Have On Polyacrylamide?
Generally, the operating temperature of polyacrylamide can be below 50℃ and above 20℃, and the effect is ideal. However, if the water temperature in the settling tank is higher, the convection disturbance of the water in the settling tank will be greater. Since polyacrylamide flocculant is a water-soluble polymer, when the temperature is too high during use, hydrolysis is likely to occur.
During the settling and diffusion process from the center to the edge of the settling tank, even if some solids have flocculated into large particles, some of them will be affected and cannot settle, thus affecting the water quality after the settlement.
polyacrylamide PAM
Polyacrylamide flocculant
The polyacrylamide Pam aqueous solution obtained by dissolving it at 30°C was heated to 35-55°C, kept for 2 hours, and then cooled to 30°C to measure the viscosity of the solution. The viscosity remained basically unchanged. It can be seen that the effect of temperature on the viscosity of the polyacrylamide Pam solution is limited to the dissolution process. . Raising the temperature after dissolution will not destroy the secondary structure, nor affect the stability of the secondary structure, nor will it affect the viscosity of the polyacrylamide solution.
