Cationic polyacrylamide price, use, function, indicators
Cationic polyacrylamide is a water-soluble polymer with a positive charge in its solution, which can adsorb negatively charged substances, effectively flocculate suspended solids and colloids with high organic matter content, and can strengthen solid-liquid separation for desilting. Because it contains a variety of active groups, it can be reacted with a variety of substances in sewage to capture, adsorption, bridge. Cationic polyacrylamide has the functions of precipitation and turbidity removal, decolorization, bonding, and strengthening slurry water separation.
At present, domestic cationic polyacrylamide is mostly prepared by binary copolymerization or ternary copolymerization, binary copolymerization is made of AM (acrylamide) and DAC (acryloyloxyethyltrimethylammonium chloride) as the main raw materials, the main raw materials of ternary copolymerization are AM, DAC, DMC (methacryloyloxyethyl trimethylammonium chloride). Compared with the exposed products and the field use, the cationic polyacrylamide prepared by the ternary copolymerization method has a wider range of adaptation than the binary copolymer products, and the effect is relatively good.
Technical indicators of cationic polyacrylamide:
Uses of cationic polyacrylamide:
Cationic polyacrylamide is mostly used in papermaking wastewater, pharmaceutical wastewater, slaughtering wastewater, urban wastewater, industrial wastewater, chemical wastewater, food factory wastewater, coal chemical wastewater, tanning wastewater, electroplating wastewater, meat product deep processing wastewater, breeding wastewater and other industries. In addition, cationic polyacrylamide can also be used as the main raw material for papermaking retention aids, fracturing thickeners, adhesives and composite flocculants.
Cationic polyacrylamide price:
Cationic polyacrylamide is mainly divided by ionization and molecular weight, many customers will basically ask how much is cationic polyacrylamide when inquiring? Or ask how much is the cationic polyacrylamide 12 million, so that the price cannot be quoted. Because the technical indicators must be clear, how much ionization and how much molecular weight must be provided, so that a better quotation. At present, the molecular weight of cationic polyacrylamide is 12 million, and the price range from 5-60 ionization is 17,000 yuan / ton - 23,000 yuan / ton. 8 million molecular weight cationic polyacrylamide, 5-60 ionization price range of 13,000 yuan / ton - 19,000 yuan / ton, the price fluctuates with the fluctuation of raw materials.
Most cationic polyacrylamide is packaged in 25 kg paper-plastic composite bags, which should be stored in a cool and ventilated place to avoid exposure to the sun, and the shelf life is two years. Note: Cationic polyacrylamide solution should be used with the mixture, because its solution degrades quickly.
