The use of cationic polyacrylamide: when used, the concentration should be controlled in. When the supporting dissolving equipment and dosing system are not used, the dissolving and dilution tank should be set up. The dosage should be adjusted according to the actual situation.
The appearance of cationic polyacrylamide is white powder, ionic 20% ~ 55%. Good water solubility, soluble in any proportion of water, insoluble in water. It is characterized by a polymer electrolyte.
Cationic polyacrylamide features: cationic polyacrylamide is a linear polymer made of cationic monomer and acrylamide copolymerization. It has the function of decolorization, adsorption, turbidity removal and adhesion.
Cationic polyacrylamide appearance is white powder particles, molecular weight is 7-13 million, ionic property is 10%-80%, with good water solubility. It is soluble in water in any proportion, but insoluble in organic solvents. Cationic polyacrylamide through the cationic groups contained in the sludge, promote the neutralization of negatively charged organic colloids in the sludge and polymer bridging aggregation, so that colloidal particles polymerization into large flocculant, suspended in suspension. The effect of liquid phase separation is obvious and the dosage is small. Cationic polyacrylamide with large molecular weight is mainly used for flocculation precipitation of water suspension and suspension. Flocculation is difficult when acidic and acidic solutions contain organic suspensions. In this case, it can effectively flocculate precipitate and exhibit different properties. The aqueous solution shall be prepared with water with a pH of 7 or less. Dilute to a diluent and hydrolyze easily. It should be used as needed or on the same day. Should not be stored for a long time.
