Qingzhou Xinrui Industry Technology Co., Ltd
No. 1177 Fengshou 2nd Road, Qingzhou City, Shandong Province, China1, Description:
PolyDADMAC liquid is a strong cation electrolyte that appears as a colorless to light yellow viscous liquid with a freezing point of -2.8°C, specific weight of 1.04 g/cm3, and a boiling point range of 280-300°C. It dissolves easily in water, is not flammable, has strong coagulation properties, good water solution stability, does not form gels, and remains stable over a wide pH range. Additionally, it is anti-chlorine and has a high charge density.

3, Application:
(1) Effluent treatment
PolyDADMAC is used in waste water treatment as a primary organic coagulant which neutralizes negatively charged colloidal material and reduces sludge volume compared with inorganic coagulants.
(2) Pulp and paper industry
PolyDADMAC is used for controlling disturbing substances in the papermaking process. It provides superior fixing of pitch from mechanical pulp and of latex from coated broke. Used in the short circulation of a paper mill to enhance retention and dewatering. In addition, it can be used to improve the efficiency of disk filters and flotators, and for cationization of fillers to provide maximal filler retention.
(3) Water purification
PolyDADMAC is used as a coagulant in water purification. It is effective in coagulating and flocculating inorganic and organic particles such as silt, clay, algae, bacteria and viruses. At high concentrations the organic polymer can remove natural organic matter such as humic and fulvic acids resulting in fewer disinfection byproduct precursors and less color.
