zetag 8847FSB 8857FSB 8858FSB can be replaced by Chinafloc EM7008 and EM8008
zetag 8847FSB,zetag8857FSB,zetag 8858FSB are three cationic emulsion polyacrylamide with 70% chagre and 80% chagre mainly used for wastewater treatment and sludge dewatering.chinafloc EM7008 and Chinafloc EM8008 can totally replace of them with good performance.
In addition to the advantages of solid polyacrylamide, the emulsion flocculant also has the advantages of large charge density selection, fast dissolution rate, low energy consumption, convenient storage and use. Compared with traditional cationic polyacrylamide products, emulsion polyacrylamide has a wider range of PH value, higher charge stability, better flocculation effect, less dosage and a series of advantages. It is also suitable for construction sites where large dissolving devices are not installed.
Emulsion polyacrylamide is widely used in all kinds of domestic sewage, chemical wastewater, oilfield sewage, sludge dehydration, paper and other fields. Polyacrylamide water-in-oil emulsion is also widely used in urban sewage treatment, brewery, amylase factory, food processing plant and other sewage treatment. It is especially suitable for the treatment of organic suspended solid flocs in acidic or acidic wastewater. In paper industry, it can be used as a retention filter, paper sewage treatment. Petroleum industry can be used as drilling emulsion coating agent or degreaser.
Cationic polyacrylamide emulsion can be divided into two types of water-in-water and oil-in-water according to the polymerization process. Its main raw materials are acrylamide and cationic quaternary ammonium salt monomer, which is polymerized through emulsifier, initiator, demulsifier and other additives. The effective content of water-in-water emulsion is low, generally 15% to 20%, and the effective content of oil-in-water emulsion is as high as about 40%, so oil-in-water polyacrylamide emulsion is higher than water-in-water emulsion.
Cationic polyacrylamide emulsion according to the ionic degree of differentiation, generally can be divided into 20, 40, 60 and 80 degrees of ion, the higher the degree of ion, the more cationic monomer contained, the higher the price. The higher the ionic degree is, the better the treatment effect is on the wastewater with high organic matter content. For different waste water, we can choose the type to determine the more suitable ionic degree and improve the cost performance.
Cationic polyacrylamide emulsion is also an important indicator according to molecular weight, generally divided into high molecular weight, high molecular weight and low molecular weight products. Because different dehydration equipment requires different flocculation effect, such as centrifuge need to choose high molecular weight products, belt filter press and screw machine need to choose high molecular weight products, plate and frame filter press choose low molecular weight products.
Cationic polyacrylamide emulsion is characterized by fast dissolution rate, high ionic degree, suitable for rapid site construction. Mainly used in sewage flocculation precipitation, sludge dehydration, paper retention aid, fracturing acidifying thickener and thickener and other industries. When it is used, it is quickly miscible with water in a certain proportion, and then injected into the sludge or solution required by the plunger or diaphragm pump, and then mixed by disturbance reaction to achieve the desired effect.
