I-Polydadmac.

Ngokuvamile isetshenziswa njenge-flocculant futhi ngezinye izikhathi ihlanganiswe ne-algicide.Amagama okuhweba ahlanganisa i-agequat400, i-St flocculant, i-pink cure, i-cat floc, njll. I-PDMDAAC inomphumela we-synergistic ne-wscp ne-poly (2-hydroxypropyl dimethyl ammonium chloride).413 imvamisa isetshenziswa njengosizo lwe-coagulant ekwelapheni amanzi ezimbonini.Ngemuva kokwengeza i-alum coagulant, umthamo we-coagulant ungasindiswa ngo-30%.Isibonelo, ngemva kokwengeza i-20 mg / L polyaluminium chloride, engeza i-0.1-0.2 mg / L I-Polydimethyldiallyl ammonium chloride ukwandisa ukusebenza kahle.

Ububanzi besisindo se-molecular of PDADMAC ngokuvamile buyi-50000 kuya ku-700000, futhi i-viscosity eguquguqukayo yesisombululo se-aqueous esingu-20% yi-50-700cps;Isisindo samangqamuzana emikhiqizo enezinga eliphezulu le-polymerization singafinyelela ku-1000000 kuya ku-300000, futhi i-viscosity eguquguqukayo yi-1000-3000 CPS.I-viscosity yangaphakathi ingu-80-300ml / g, futhi i-viscosity ephezulu ingafinyelela ku-1440ml / g.Umkhiqizo ngokuvamile uyisixazululo esingu-10-50% esinomthamo we-1.02-1.10 g / ml.Umthamo emanzini okuphuza udingeka ube ngaphansi kuka-10mg/L (Taiwan).

Ukuziphatha kwe-viscosity kwesisombululo samanzi se-PDMDAAC kunomphumela obalulekile we-polyelectrolyte.I-viscosity ye-intrinsic iyancipha ngokwanda kokugxila kasawoti okungeziwe.Uma ukugxilwa kwe-NaCl kungaphezu kwe-1 m, ukuguqulwa kwe-viscosity yangaphakathi ngokugxila kasawoti okungeziwe kuncane kakhulu.I-viscosity yangaphakathi ikalwa nge-viscometer ye-Ubbelohde kusixazululo esingu-1 M NaCl ku-30 ​​℃, futhi isisindo se-viscosity esimaphakathi se-molecular singatholakala ngokuya ngefomula.

Isisindo samangqamuzana e-PDMDAAC singatholakala kufomula elandelayo, lapho i-viscosity yangaphakathi ikalwa ngesixazululo esingu-1 M NaCl ku-30 ​​℃: 407.

[ η] = 1.12 * 10-4M0.amashumi ayisishiyagalombili nambili

U-Huang noReichert bafunde ukwehla kwesisindo esishisayo se-PDMDAAC kumazinga okushisa ahlukene.53.3-130 ℃ ukwehla kwesisindo kungenxa yokuncipha kwamanzi;Gcina ungashintshiwe phakathi kuka-130-200 ℃;Ukuncipha kwesisindo ku-200-310 ℃ kungu-41.4%, okubangelwa ukubola okushisayo.Alikho iphuzu lokuncibilika elitholakele phakathi nayo yonke inqubo yokushisisa.Izinga lokushisa lokushintsha kwengilazi le-PDMDAAC elinesisindo samangqamuzana angama-33 kDa lingu-8 ℃.

I-PDADMAC ayinabuthi obuncane ku-rainbow trout kune-chitosan (Waller et al. 1993).Kodwa-ke, i-PDDMAC yokwelashwa kwamanzi inemikhawulo kokuqukethwe kwe-monomer.

I-PDMDAAC e-China inokuqukethwe okuphezulu kwe-monomer.I-PDMDAAC yezitshalo zamakhemikhali ezimbili yahlolwa futhi yathola ukuthi okuqukethwe kwe-monomer kwakungu-12.5% ​​no-7.89% (kubalwe njengokuqinile. Kuguqulelwe ku-40%, okuqukethwe emkhiqizweni kube ngu-5.0% no-3.2%), okwakukukhulu kakhulu kune-American. Izinga lika-0.2% kanye nezinga laseYurophu lika-0.5%.380 ngemikhiqizo enokuqukethwe kwe-monomer engacacisiwe, okuqukethwe kwe-monomer kungase kube phezulu.I-viscosity yangaphakathi ye-PDMDAAC equkethe i-monomer inikezwa ngefomula elandelayo: 411.
