    Use of cationic polyacrylamide

    2012/8/11      view:

        The product is made of cationic monomers (DM, DMC, CPF, DMDAAC, DMAEMA, etc.) and acrylamide, which are granulated, dried and smashed into small white particles or powders. Cationic polyacrylamide (CPAM) is a linear polymer. Because it has a variety of active groups, it can be adsorbed and adsorbed to form hydrogen bonds with many substances. Mainly flocculation the negatively charged colloid, with the removal of turbidity and decoloring, adsorption, adhesion and other functions, suitable for dyeing wastewater, papermaking, food, building, metallurgy, mineral processing, coal, oil, aquatic products processing and fermentation industries such as high content, dehydration treatment is especially suitable for the city, city sewage sludge, papermaking sludge and other industrial sludge.
        Sludge dewatering
        According to the nature of the sludge, the corresponding model of this product can be selected. It is effective to dehydrate the gravity sludge before the sludge enters the pressure filter. When dehydration, large floc, non stick filter cloth, no flow in pressure filtration, less dosage, high efficiency and low water content of mud cake. This product has positive electricity in acidic or alkaline medium, so it is very effective for flocculating and clarifying the suspended particles with negative charge in sewage. Such as alcohol plant wastewater, brewery wastewater, monosodium glutamate factory wastewater, sugar factory wastewater, meat factory wastewater, beverage factory wastewater, textile printing and dyeing plant wastewater, etc. With cationic polyacrylamide to several times or tens of times compared with anionic polyacrylamide, nonionic polyacrylamide or inorganic salt effect, because this kind of wastewater generally with negative charge.
        Papermaking auxiliaries
        It can be used as paper dry strength agent, retention aid and filter aid, which can greatly improve the quality of paper, save cost and improve the production capacity of paper mill. Can be directly with inorganic salt ions, fiber and other organic polymer in order to enhance the effect of electrostatic bridge the physical strength of the paper, reduce the loss of fiber or filler, accelerate filter water, strengthening, retention and drainage effect, also can be used for the treatment of white water, at the same time, can play a significant flocculation in deinking process in. At the same time, the product is also a highly efficient dispersant.
