Different uses:


Non-ionic polyacrylamide uses:

Sewage treatment agent: when the suspended sewage is acidic, the use of non-ionic polyacrylamide and flocculant is more appropriate. This is PAM adsorption bridge role, so that the suspended particles flocculation precipitation, to achieve the purpose of sewage purification. Can also be used for the purification of tap water, especially with the use of inorganic flocculant, the best effect in water treatment. Textile industry auxiliaries: add some chemicals can be made into chemical data, used for textile sizing. Sand control and sand fixation: non-ionic polyacrylamide dissolved into 0.3% concentration to add crosslinking agent, spray on the desert can play a role in sand control and sand fixation. Soil humectant: used as soil humectant and various modified polyacrylamide basic raw materials.


Cationic polyacrylamide uses:


Sludge dewatering: according to the nature of pollution can choose the corresponding brand of this product, can effectively in the sludge into the pressure filter before gravity sludge dewatering. Dehydration, the production of large flocs, non-stick filter cloth, in the pressure of the filter does not disperse, less dosage, high dehydration efficiency, mud cake moisture content in 80% below. Sewage and organic waste water processing: the product in acidic or alkaline medium is electropositive, so that the suspended particles in wastewater with negatively charged sewage flocculation precipitation, clarification is very effective, such as alcohol plant waste water, brewery wastewater and gourmet powder factory wastewater, sugar refinery wastewater, meat food factory waste water, beverage factory waste water, textile dyeing wastewater, etc., with cationic polyacrylamide Compared with anionic polyacrylamide, non-ionic polyacrylamide or inorganic salt, the effect is several times or tens of times higher, because this kind of wastewater is generally negative charge. Flocculant for water treatment of waterworks: this product has the characteristics of less dosage, good effect and low cost, and it has better effect when combined with inorganic flocculant. Oilfield chemicals: such as clay antiswelling agent, thickening agent for oilfield acidification, etc. Paper additives: cationic PAM paper strengthening agent is a water-soluble cationic polymer containing amino formyl, with strengthening, retention, filtration and other functions, can effectively improve the strength of paper. The product is also a highly effective dispersant.


Anionic polyacrylamide uses:


Industrial wastewater treatment: for suspended particles, relatively high concentration, particles with positive charge, PH value of water neutral or alkaline sewage, iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, the best effect. Drinking water treatment: The water source of many waterworks in China comes from rivers, with high sediment and mineral content and turbidity. Although filtered by precipitation, it still cannot meet the requirements. Flocculant needs to be added, and the dosage is 1/50 of inorganic flocculant, but the effect is several times that of inorganic flocculant. For serious organic pollution of river water can be used inorganic flocculant and my company's cationic polyacrylamide with better effect. Starch factory and a loss of alcohol plant starch grains recycling: now a lot of a lot of waste water containing starch starch factory, now adding the anionic polyacrylamide, the starch particles flocculation precipitation, and then to pass through the filter press filter sediment into the pie, as feed, alcohol plant also can be used anionic polyacrylamide dehydration of alcohol, filter for recycling.
