When cationic polyacrylamide dissolves water, sprinkle the product evenly into the stirred water, and heat properly.
Principle of flocculation: cationic polyacrylamide for flocculation, related to the surface properties of the floc, especially the suspension of the potential, viscosity, turbidity, PH value. The electrodynamic potential of particle surface is the cause of particle polymerization. The addition of PAM with opposite surface charge can reduce the galvanic potential and cause coagulation. But the quality and dosage of polyacrylamide must be controlled, because there will inevitably be a small amount of unpolymerized acrylamide monomer in polyacrylamide, with gun neurotoxicity and teratogenic, carcinogenic, mutagenic effects. The high concentration of acrylamide monomer in drinking water is 0.01 mg/L..
Cationic polyacrylamide application: polymer types, specifications, dosage and proportioned concentration. Aluminum sulfate PAM is polyacrylamide. There are three main types of PAM, namely anionic, cationic, and anionic. Depending on the type of ion, the required solution environment is different, and anions work better in basic conditions.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
