| titleOfInvention | The preparation method of micro- crosslinking net hydrophobic-associatcationic cationic polyacrylamide flocculant |
| abstract | The invention discloses a kind of preparation method of micro- crosslinking net hydrophobic-associatcationic cationic polyacrylamide flocculant：First, the surface active monomer containing hydrophobic structure is synthesized in ethanol solution, will be mixed and stirred for dissolving with certain proportion with acrylamide, cationic monomer and crosslinking agent after the scrubbed drying of surface active monomer, acid adding or alkali regulation reaction solution pH to 5 ~ 7；Azo initiator is eventually adding, under nitrogen protection, 40 ~ 80 o 3 ~ 10h is reacted in C waters bath with thermostatic control, micro- crosslinking net hydrophobic-associatcationic cationic polyacrylamide flocculant powder is obtained after absolute ethyl alcohol is washed, dried.Heat resistance and salt tolerance is more preferable between the flocculating agent molecule, is advantageous to the effect of the Contact-sorption of the organic substance particle in sewage, builds bridge, volume is swept, trapping effect is also stronger, the flco of formation is bigger, floc settling velocity faster, the dosage of flocculant is also less；And salt tolerance, thermostability and the anti-shear ability of the flocculant prepared are also superior to traditional flocculant. |
