What are the techniques for the dissolution of polyacrylamide?
When preparing polyacrylamide solution, first dissolve polyacrylamide, and then add it to water, because polyacrylamide is a polymer, in order to ensure its full dissolution, it must be carried out at room temperature. This requires us to choose the appropriate dissolution method when dissolving polyacrylamide, which is introduced to you below.
First, let's understand the solubility of polyacrylamide.
Polyacrylamide is a high molecular weight flocculant in aqueous solution, and the larger its molecular weight, the easier it is to dissolve in water. Polyacrylamide aqueous solution is a colorless transparent solution with viscoelasticity, high viscosity, rapid dispersion and emulsification in water, which is conducive to flocculation. Polyacrylamide aqueous solution is relatively stable to heat and acid.
