When cationic polyacrylamide is dissolved, normal temperature, clean water is generally used. It is found through experiments that cationic polyacrylamide usually takes 90 minutes to be completely dissolved in an aqueous solution at room temperature, provided that it is dissolved under stirring. When the water temperature is close to 60, the dissolution speed of cationic polyacrylamide is the fastest, and it can be dissolved within 60 minutes. However, once the water temperature exceeds 60 degrees Celsius, the molecular structure of cationic polyacrylamide will be affected and destroyed, thereby affecting the use effect
found that as long as the water temperature is not lower than 4 degrees Celsius, it will not affect the dissolution of cationic polyacrylamide. However, in the case of low temperature in winter, attention should be paid to monitoring the water temperature in the molten pool and should not be too low. If the temperature is too low, the dissolution of cationic polyacrylamide will be greatly affected.
At the same time, pay attention to the storage of cationic polyacrylamide. When the temperature is too low, cationic polyacrylamide is easy to freeze and harden. When the cured cationic polyacrylamide is dissolved, it will be difficult to dissolve, which will affect the flocculation effect.
