Cationic Temperature-Resistant Salt-Resistant Polyacrylamide for Printing And Dyeing Wastewater Treatment in Japan

Dec 01, 2010 · At baking temperature of 60 °C and 80 °C, cationic agent is not fixed firmly on the cotton and its desorption occurs in the dye-bath, so that the dye exhaustion is relatively low. At baking temperature of 100°C or higher, the cationic agent is firmly fixed and dye ex- …

Cationic polyacrylamide, is a white powder water -soluble polymer which is copolymerized by cationic monomer and acrylamide. It has the function of decolorizing, adsorbing, turbid eliminating and bonding. It generate a good flocculation and …

6. It is used for textile and printing and dyeing industries. Cationic polyacrylamide is a protective la yer of a fabric treatment of the slurry finishing agent and a protective la yer that can be formed into a soft anti-wrinkle and anti-bacteria. Using its characteristics of moisture absorption the discharging rate when the spinning yarn is ...

V. Grumezescu, ... M.C. Chifiriuc, in Antibiotic Resistance, 2016 Polyacrylamide. Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Beinease the settling rate of bacterial floc and improve the capture of dispersed bacterial cells, suspended solids, and …

cationic flocculant (polyacrylamide) used for municipal wastewater treatment Polyacrylamide is a linear polymer comprised of monomers unit with functional groups of amide that adsorb on to the surface of particles. These particles are bridged together by the long polymer chain drawing the particles closer together.

Cationic polyacrylamide emulsions with ultra-high concentration (CPAME-uhc) can obviously save transportation costs, but their molecular weight, solubility, and temperature/salt resistance need to be further improved. Therefore, this study attempted to improve the molecular weight of CPAME-uhc by optimizing the preparation conditions.
