Polyacrylamide (Zetag 4100 4105) can be replaced by the Chinafloc series
Anionic polyacrylamide main uses:
1, anionic polyacrylamide according to different uses and user requirements for product performance, can choose different molecular weight use.
2, used for industrial wastewater treatment, especially for suspended particles, coarse, high concentration, particles with positive charge, PH value of water is neutral, alkaline sewage such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment effect is very good.
3. Used for drinking water treatment. Many waterworks water from rivers in our country, more cloudy, a lot of water plant using inorganic flocculants, but the large amount of additive, causing sludge quantity increases the result is bad, the anionic polyacrylamide, dosing quantity is one of the inorganic flocculating 50 points, but the effect is inorganic flocculant several times or more, especially my company production of polyacrylamide, close to international advanced level.
4, used for starch loss and distillery distillery recovery. Now many starch factory discharge wastewater starch is very high, after the discharge of the impact on the environment, waste resources, add PAM, so that the starch precipitation, the precipitate by the press filter into cake can be used as feed. A large number of distillers' grains are used in this process. An Asian distiller in Heilongjiang province is the polyacrylamide produced by our company, which is recycled for distillers' grains and has achieved great economic benefits.
5. Used as a water plugging agent for profile control and water plugging in oil field, and a driving agent for three oil recovery.
6, used as papermaking additives, PAM is widely used in papermaking, can be used as long fiber papermaking dispersant, dry and wet reinforcement, retention, filter aid and flocculant of papermaking wastewater.
Cationic polyacrylamide main uses:
Polyacrylamide cation for organic flocculant, used for domestic sewage and organic wastewater treatment, the product in acidic or alkaline media are positive, so the sewage with negative charge flocculation precipitation, clarification is very effective. Such as the production of food alcohol wastewater, papermaking wastewater, wastewater from urban sewage treatment plants, beer wastewater, gourmet wastewater, sugar wastewater, high organic content wastewater, feed wastewater, textile printing and dyeing wastewater, with cationic polyacrylamide than anionic, non-ionic polyacrylamide effect is several times or tens of times higher.
Non-ionic polyacrylamide main uses:
Nonionic polyacrylamide is a water-soluble polymer or polyelectrolyte. High purity, low degree of ionization, good performance, wide use, mainly used in a variety of modified polyacrylamide basic raw materials. Such as anionic polyacrylamide, according to the use of different grades of non-ionic polyacrylamide as basic raw materials for hydrolysis. Non-ionic polyacrylamide can be added to a number of other chemicals can be formulated as a chemical sizing, used for textile sizing, can improve permeability and desizing performance. Non-ionic polyacrylamide can also be used for all kinds of industrial wastewater flocculation sedimentation, which is PAM is the adsorption bridge, so that the suspended particles flocculation precipitation. Achieve the purpose of purifying water.
Main uses of amphoteric ion polyacrylamide:
Amphoteric polyacrylamide contains cationic base and anion base because of its molecule, it has the characteristics of the use of general cationic flocculant, showing more excellent performance. These flocculants can be used over a wide range of PH values, with higher water filtration, lower filter cake moisture content, and can also be used for strong acid leaching of ore or recovery of valuable metals from acidic catalysts containing metals. Amphoteric ionic is not a mixture of anionic and cationic. If the use of cationic polyacrylamide and anionic polyacrylamide will react to produce precipitation. So zwitterionic products are more ideal. Amphoteric polyacrylamide is widely used in municipal sewage treatment plants, breweries, food factories, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industry and cosmetics and other sludge dewatering fields.
