Inowanzo shandiswa se flocculant uye dzimwe nguva inosanganiswa nealgicide.Mazita ekutengeserana anosanganisira agequat400, St flocculant, pink cure, cat floc, etc. PDMDAAC ine synergistic effect ne wscp uye poly (2-hydroxypropyl dimethyl ammonium chloride).413 inowanzo shandiswa se coagulant rubatsiro mukurapwa kwemvura mumaindasitiri.Mushure mekuwedzera alum coagulant, iyo dosage ye coagulant inogona kuponeswa ne30%.Semuenzaniso, mushure mekuwedzera 20 mg / L polyaluminium chloride, wedzera 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride kuti uwedzere kushanda.

Iyo molecular weight range yePDADAC inowanzoita 50000 kusvika 700000, uye dynamic viscosity ye 20% aqueous solution ndeye 50-700cps;Huremu hwemamorekuru ezvigadzirwa zvine dhigirii repamusoro repolymerization hunogona kusvika 1000000 kusvika 300000, uye iyo dynamic viscosity ndeye 1000-3000 CPS.Iyo intrinsic viscosity ndeye 80-300ml / g, uye iyo yakakwira viscosity inogona kusvika 1440ml / g.Chigadzirwa chacho kazhinji 10-50% mhinduro ine density ye 1.02-1.10 g / ml.Iyo dosage mumvura yekunwa inodiwa kuve isingasviki 10mg / L (Taiwan).

Iyo viscosity maitiro ePDMDAAC aqueous mhinduro ine yakakosha polyelectrolyte mhedzisiro.Iyo intrinsic viscosity inoderera nekuwedzera kweiyo yakawedzera munyu.Kana iyo NaCl yakawedzera kupfuura 1 m, shanduko yemukati viscosity ine yakawedzera munyu munyu ishoma.Iyo intrinsic viscosity inoyerwa neUbbelohde viscometer mu1 M NaCl mhinduro pa30 ℃, uye viscosity avhareji yemamorekuru huremu hunogona kuwanikwa zvichienderana neformula.

Iyo molecular huremu hwePDMDAAC inogona kuwanikwa kubva kune inotevera formula, umo iyo intrinsic viscosity inoyerwa mu1 M NaCl mhinduro pa30 ℃: 407.

Huang naReichert vakadzidza kuderera kwehuremu hwePDMDAAC munzvimbo dzakasiyana dzekushisa.53.3-130 ℃ kuora muviri kunokonzerwa nekurasikirwa kwemvura;Ramba usina kuchinjwa pakati pe130-200 ℃;Kurasikirwa kwehuremu pa200-310 ℃ ndeye 41.4%, iyo inokonzerwa nekuora kwekupisa.Hapana kunyungudika kwakawanikwa panguva yese yekudziya.Iyo tembiricha yekuchinja yegirazi yePDMDAAC ine huremu hwemamorekuru hwe33 kDa ndeye 8 ℃.

PDADAC haina muchetura kune murarabungu trout pane chitosan (Waller et al. 1993).Nekudaro, PDADAC yekurapwa kwemvura ine zvirambidzo pane monomer yemukati.

PDMDAAC muChina ine yakakwira monomer yemukati.PDMDAAC yemiti miviri yemakemikari yakaedzwa uye yakawana kuti monomer zviri mukati maive 12.5% ​​uye 7.89% (yakaverengwa seyakasimba. Yakashandurwa kusvika ku40%, zvinyorwa muzvigadzirwa zvaive 5.0% uye 3.2%), iyo yakanga yakakura kudarika yeAmerica. Chiyero che0.2% uye chiyero cheEuropean che0.5%.380 yezvigadzirwa zvisina kutsanangurwa monomer zvemukati, iyo monomer yemukati inogona kunge yakakwira.Iyo intrinsic viscosity yePDMDAAC ine monomer inopihwa neinotevera fomula: 411.
