1. Component optimization: adjust the formula of polyacrylamide, including the molecular weight, charge density and charged groups of polyacrylamide, to make the floc denser.
2. Optimization of reaction conditions: By adjusting the reaction conditions such as reaction temperature, reaction time and pH value, the reaction process of polyacrylamide was optimized to improve the density of floc.
3. Adding additives: Adding some additives can improve the floc density of polyacrylamide, such as inorganic salts and organic modifiers.
4. Mechanical stirring: In the flocculation reaction, proper stirring mode and intensity are helpful to improve the density of floc.
5. Temperature control: By controlling the temperature of flocculation reaction, the floc density of polyacrylamide can be affected to some extent.
It should be noted that the above methods are only general suggestions, and the specific implementation methods and technical details need experimental verification and patent application. If you have specific practical needs, please consult professional chemical experts or technicians for more accurate advice and guidance.
