The main purpose of cationic polyacrylamide
2015-02-14 08:46:02
Cationic polyacrylamide (CPAM) features: cationic polyacrylamide (CPAM) appearance is white powder, ion ratio from 20% to 55% water solubility is good, can in any proportion are dissolved in water and soluble in organic solvent. The characteristics of the high polymer electrolyte, polyacrylamide is suitable for wastewater with negative charge and rich in organic matter processing. Treatment of wastewater of polyacrylamide is suitable for dyeing, papermaking, food, building, metallurgy, mineral processing, coal, oil, aquatic products processing and fermentation etc organic colloid content high, dehydration treatment polyacrylamide is especially suitable for urban sewage, urban sewage sludge, papermaking sludge and other industrial sludge.
Cationic polyacrylamide main purposes:
1) polyacrylamide used for sludge dewatering sludge nature of the choice of relative grade according to the product, can be effective before the sludge into the filter press sludge dewatering, polyacrylamide dewatering, floc, non stick cloth, not powder filter, the flow of mud cake thick, high dewatering efficiency, moisture rate below 80%.
2) polyacrylamide for sewage and organic wastewater treatment, this product showed a cationic with or alkaline medium, so the sewage in the suspended particle negatively charged sewage flocculation, clarification is very effective. Polyacrylamide such as the production of grain alcohol wastewater, papermaking wastewater, wastewater, urban sewage treatment plant of beer wastewater, monosodium glutamate wastewater, sugar wastewater, high organic content wastewater feed wastewater, textile printing and dyeing wastewater, with cationic polyacrylamide than with anionic, nonionic polyacrylamide or the effect of inorganic salts to be several times or dozens of times, because this waste water is generally negative charge.
3) polyacrylamide flocculant for treatment, with the river water water water less dosage, good effect, low cost, especially and inorganic flocculant has better effect, it will become a high efficient flocculant in water plant to the Yangtze River, the Yellow River and other river basin.
4) reinforcing agent and other additives with Polyacrylamide in papermaking.
5) polyacrylamide used in oil field has additives, such as clay anti swelling agent, thickening agent used in oil field acidification.
