I-PolydadMac.

Imvamisa isetshenziswa njenge-flocculant futhi kwesinye isikhathi ihlanganiswe ne-algicide. Amagama okuhweba afaka i-Agequat400, i-St Flocculant, ikhambi le-Pink, i-Cat Floc, njll. Pdmdaac inomphumela we-pernergistic nge-WSCP ne-POLY (2-Hydroxypropyly). I-413 ngokuvamile isetshenziswa njengosizo oluhlanganayo ekwelashweni kwamanzi kwezimboni. Ngemuva kokungeza i-alum coagulant, umthamo we-coabulant ungalondolozwa ngama-30%. Isibonelo, ngemuva kokungeza i-20 mg / l polyaluminium chloride, engeza u-0.1-0.2 mg / l polydimethyllilyl ammonium chloride ukwandisa ukusebenza kahle.

Ububanzi besisindo se-molecular le-PDADMAC buvame ukuba ngo-50000 kuya ku-700000, kanye nokubonakala okunamandla kwesisombululo samanzi angama-20% kungama-50-700cps; Isisindo samangqamuzana semikhiqizo enezinga eliphakeme le-polymerization lingafinyelela ku-1000000 kuye ku-300000, futhi i-viscosity enamandla i-1000-3000 CPS. I-viscosity eyimfihlo ingu-80-300ml / g, futhi i-viscosity ephezulu ingafinyelela ku-1440ml / g. Umkhiqizo ngokuvamile uyisixazululo se-10-50% esinobunzima be-1.02-1.10 g / ml. Umthamo emanzini okuphuza adingekayo ukuze ube ngaphansi kwe-10mg / L (Taiwan).

Ukuziphatha kwe-Viscosity ye-PDMDAAC AMECEOL khangela inomphumela omkhulu we-polyelectrolyte. I-Intrinsic Viscosity inciphisa ngokwanda kokuhlushwa usawoti owengeziwe. Lapho ukugxila kwe-NACL kukhulu kune-1 m, ukuguqulwa kwe-viscosity engaphakathi kokuhlushwa usawoti okungeziwe kuncane. I-viscosity engaphakathi ilinganiswa nge-Ubbelohde Viscometer ku-1 M nacl Solution ngo-30 ℃, futhi isisindo esimaphakathi samangqamuzana singatholwa ngokuya ngefomula.

Isisindo se-molecular se-PDMDAAC singatholakala kwifomula elandelayo, lapho i-viscosity ephakathi ilinganiswa khona ngesisombululo esingu-1 m nacl ngo-30 ℃: 407.

UHuang noReichert bafunda ukuncipha kwesisindo okushisayo kwe-PDMDAC kumabanga okushisa ahlukene. 53.3-130 ℃ Ukuncipha kwesisindo kungenxa yokulahleka kwamanzi; Gcina ungashintshi phakathi kuka-130-200 ℃; Ukwehla kwesisindo ngo-200-310 ℃ ngu-41.4%, okubangelwa ukubola okushisayo. Alikho iphuzu elincibilikayo elitholakale ngesikhathi senqubo yonke yokushisa. Ukushisa kwengilazi kwe-Glass ye-PDMDAAC ngesisindo samangqamuzana esingu-33 kda kungu-8 ℃.

I-PDADMAC ayinobuthi obunobuthi ku-rainbow trout kune-chitosan (waller et al. 1993). Kodwa-ke, i-PDADMAC yokwelashwa kwamanzi inemikhawulo kokuqukethwe kwe-monomer.

I-PDMDAAC eChina inokuqukethwe okuphezulu kwe-monomer. I-PDMDAAC yezitshalo ezimbili zamakhemikhali yahlolwa futhi yathola ukuthi okuqukethwe kwe-monomer kwakungu-12.5% ​​futhi 789% (kubalwe njenge-40%, okuqukethwe kukhulu. 380 yemikhiqizo enokuqukethwe okungacacisiwe monomer, okuqukethwe kwe-monomer kungenzeka kube ngaphezulu. Ukubonakaliswa okungaphakathi kwe-PDMDAAC equkethe i-monomer kunikezwa yifomula elandelayo: 411.
