Nonionic polyacrylamide emulsion high cost performance, stable performance, the product cost are lower than those of general emulsion, better solubility, dissolve in about 10 minutes, the effect is tiny colloidal particles and suspension particles under the action of colloidal substance or electrolyte, and particle surface charge, reduce or eliminate the repulsive force between particles. The particles are bound together, and the volume keeps growing. When the particles gathe...
