According to the characteristics of cationic polyacrylamide, the application scale of cationic polyacrylamide was determined. Because cationic polyacrylamide has the following functions: cleaning and purification, settlement promotion, filtration promotion, thickening and other functions. Therefore, we can fully meet the requirements of waste liquid treatment, sludge concentration and dehydration, mineral processing, coal washing, paper making and other aspects.
The application of cationic polyacrylamide is described: additives such as paper strengthening agents. Used in oil field economic additives, such as clay anti-expansion agent, oil field acidifying thickener. According to the nature of the sludge, the corresponding type of this product can be selected, which can be used for sludge dehydration before the sludge enters the filter press. When dewatering, the flocculus is large, the filter cloth is non-stick, the filter press is not dispersed, the mud cake is thick, the dehydration efficiency is good, and the moisture content of the mud cake is less than 80%. For the treatment of daily sewage and organic wastewater, this product is positively charged in the compound or alkaline medium, and is very useful for the flocculation of sewage with negative charge in suspended particles. Such as grain alcohol wastewater, papermaking wastewater, urban sewage treatment plant wastewater, beer wastewater, monosodium glutamate plant wastewater, sugar wastewater, wastewater with high organic content, feed wastewater, textile printing and dyeing wastewater. The effect of using cationic polyacrylamide is several times or tens of times that of anionic, non-ionic polyacrylamide or inorganic salts, because these wastewater are all over with negative charges. The tap water with river water as the source of flocculant consumption is less, the effect is good, the cost is low, especially with the inorganic flocculant compound effect is better, become the flocculant of water plant.
