Polyacrylamide (PAM) is a linear water-soluble polymer, is one of the most widely used water-soluble polymer compounds, PAM and its derivatives can be used as efficient flocculant, thickener, paper strengthening agent and liquid drag reduction agent. Widely used in water treatment, paper, petroleum, coal, mining and metallurgy, geology, textile, construction and other industrial sectors.
Non-ionic polyacrylamide: Use: sewage treatment agent: When the suspended sewage is acidic, the use of non-ionic polyacrylamide as flocculant is more suitable. This is the PAM adsorption bridge function, so that the suspended particles produce flocculation precipitation, to achieve the purpose of purifying sewage. It can also be used for the purification of tap water, especially in combination with inorganic flocculants, which has the best effect in water treatment. Textile industry additives: adding some chemicals can be matched into chemical materials for textile sizing. Anti-sand fixation: The non-ionic polyacrylamide dissolved into 0.3% concentration and added crosslinking agent, spraying on the desert can play a role in preventing sand fixation. Soil humectant: used as soil humectant and various modified polyacrylamide basic raw materials.
Cationic polyacrylamide: Use: sludge dehydration: according to the nature of the pollution can choose the corresponding brand of this product, can effectively in the sludge into the press filter before gravity sludge dehydration. When dewatering, it produces large floc, non-stick filter cloth, does not disperse when pressing filter, less dosage, high dehydration efficiency, and the moisture content of mud cake is below 80%.
Sewage and organic wastewater treatment: this product in the acidic or alkaline medium are positive, so the sewage suspended particles with negative charge flocculation precipitation, clarification is extremely effective, such as alcohol factory wastewater, brewery wastewater, monosodium glutamic wastewater, sugar factory wastewater, meat and food factory wastewater, beverage factory wastewater, textile printing and dyeing factory wastewater, with cationic polyacrylamide It is several times or tens of times higher than the effect of anionic polyacrylamide, non-ionic polyacrylamide or inorganic salts, because such wastewater is generally negatively charged.
Water treatment flocculant: the product has the characteristics of small dosage, good effect and low cost, especially the combination with inorganic flocculant has a better effect. Oilfield chemicals: such as clay anti-swelling agent, thickening agent for oilfield acidification, etc. Paper additives: Cationic PAM paper reinforcement is a water-soluble cationic polymer containing amino formyl, with strengthening, retention, filtration and other functions, can effectively improve the strength of paper. At the same time, the product is also a highly effective dispersant.
Anionic polyacrylamide: Use: Industrial wastewater treatment: for suspended particles, more out, high concentration, particles with positive charge, water PH value is neutral or alkaline sewage, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, the best effect.
Drinking water treatment: Many water plants in China come from rivers, sediment and mineral content is high, relatively turbidity, although after precipitation filtration, still can not meet the requirements, need to add flocculant, dosage is inorganic flocculant 1/50, but the effect is several times of inorganic flocculant, For the river water with serious organic pollution, inorganic flocculant and cationic polyacrylamide of our company can be used together to achieve better results.
Recovery of lost starch lees in amylating plants and alcohol plants: many amylating plants now contain a lot of starch in the wastewater, adding anionic polyacrylamide to flocculate and precipitate starch particles, and then the sediment is filtered by the filter press into a cake shape, which can be used as feed, alcohol in the alcohol factory can also be dehydrated by anionic polyacrylamide and recovered by press filtration.
