I-Polydadmac.

Ngokuvamile isetshenziswa njenge-flocculant futhi ngezinye izikhathi ihlanganiswe ne-algicide. Amagama okuhweba afaka phakathi i-agequat400, i-St flocculant, i-pink cure, i-cat floc, njll. I-PDMDAAC inomphumela wokubambisana ne-wscp kanye ne-poly (2-hydroxypropyl dimethyl ammonium chloride). I-413 ivame ukusetshenziswa njengosizo lwe-coagulant ekuhlanzweni kwamanzi ezimbonini. Ngemva kokufaka i-alum coagulant, umthamo we-coagulant ungagcinwa ngo-30%. Isibonelo, ngemuva kokufaka i-20 mg / L polyaluminium chloride, engeza i-0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride ukuze kwandiswe ukusebenza kahle.

Ububanzi besisindo sama-molecule e-PDADMAC buvame ukuba phakathi kuka-50000 kuya ku-700000, kanti i-dynamic viscosity yesisombululo samanzi esingu-20% ingu-50-700cps; Isisindo sama-molecule semikhiqizo enezinga eliphezulu le-polymerization singafinyelela ku-1000000 kuya ku-300000, kanti i-dynamic viscosity ingu-1000-3000 CPS. I-intrinsic viscosity ingu-80-300ml / g, kanti i-viscosity ephezulu ingafinyelela ku-1440ml / g. Umkhiqizo ngokuvamile uyisisombululo esingu-10-50% esinobuningi obungu-1.02-1.10 g / ml. Isilinganiso emanzini okuphuza siyadingeka sibe ngaphansi kuka-10mg / L (eTaiwan).

Ukuziphatha kwe-viscosity kwesisombululo samanzi se-PDMDAAC kunomphumela obalulekile we-polyelectrolyte. I-viscosity yangaphakathi iyancipha ngokwanda kokuhlushwa kukasawoti owengeziwe. Lapho ukuhlushwa kwe-NaCl kungaphezu kwe-1 m, ushintsho lwe-viscosity yangaphakathi ngokuhlushwa kukasawoti owengeziwe luncane kakhulu. I-viscosity yangaphakathi ilinganiswa yi-Ubbelohde viscometer kusisombululo se-NaCl esingu-1 M ku-30 ​​℃, futhi isisindo sama-molecule esijwayelekile se-viscosity singatholakala ngokuya ngefomula.

Isisindo sama-molecule se-PDMDAAC singatholakala kule fomula elandelayo, lapho i-viscosity yangaphakathi ilinganiswa khona kusisombululo se-1 M NaCl ku-30 ​​℃: 407.

UHuang noReichert bafunde ngokulahlekelwa isisindo sokushisa kwe-PDMDAAC emazingeni okushisa ahlukene. Ukulahlekelwa isisindo okungu-53.3-130 ℃ kungenxa yokulahlekelwa amanzi; Gcina kungashintshiwe phakathi kuka-130-200 ℃; Ukulahlekelwa isisindo ku-200-310 ℃ kungu-41.4%, okubangelwa ukubola kokushisa. Akukho phuzu lokuncibilika elitholakale phakathi nenqubo yonke yokushisa. Izinga lokushisa lokushintsha kwengilazi le-PDMDAAC elinesisindo sama-molecule esingu-33 kDa lingu-8 ℃.

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

I-PDMDAAC eShayina inokuqukethwe okuphezulu kwe-monomer. I-PDMDAAC yezitshalo ezimbili zamakhemikhali ihlolwe futhi yathola ukuthi okuqukethwe kwe-monomer kwakuyi-12.5% ​​kanye ne-7.89% (kubalwe njengokuqinile. Iguqulwe yaba yi-40%, okuqukethwe kumkhiqizo kwakuyi-5.0% kanye ne-3.2%), okwakukhulu kakhulu kune-American Standard engu-0.2% kanye ne-European standard engu-0.5%. 380 yemikhiqizo enokuqukethwe kwe-monomer okungacacisiwe, okuqukethwe kwe-monomer kungaba phezulu. I-viscosity yangaphakathi ye-PDMDAAC equkethe i-monomer inikezwa yifomula elandelayo: 411.
