I-Polydadmac.

Ihlala isetyenziswa njenge-flocculant kwaye ngamanye amaxesha idityaniswe ne-algicide. Amagama orhwebo aquka i-agequat400, i-St flocculant, i-pink cure, i-cat floc, njl. I-PDMDAAC inefuthe elihambelanayo ne-wscp kunye ne-poly (2-hydroxypropyl dimethyl ammonium chloride). I-413 isetyenziswa ngokubanzi njengoncedo lwe-coagulant kunyango lwamanzi kwimizi-mveliso. Emva kokongeza i-alum coagulant, idosi ye-coagulant ingagcinwa nge-30%. Umzekelo, emva kokongeza i-20 mg / L polyaluminium chloride, yongeza i-0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride ukwandisa ukusebenza kakuhle.

Uluhlu lobunzima beemolekyuli zePDADMAC ludla ngokuba phakathi kwama-50000 ukuya kuma-700000, kwaye i-dynamic viscosity yesisombululo samanzi esingama-20% yi-50-700cps; Ubunzima beemolekyuli zeemveliso ezinezinga eliphezulu le-polymerization bunokufikelela kwi-1000000 ukuya kuma-300000, kwaye i-dynamic viscosity yi-1000-3000 CPS. I-intrinsic viscosity yi-80-300ml / g, kwaye i-viscosity ephezulu inokufikelela kwi-1440ml / g. Imveliso ngokubanzi yisisombululo se-10-50% esinobunzima be-1.02-1.10 g / ml. Idosi emanzini okusela kufuneka ibe ngaphantsi kwe-10mg / L (eTaiwan).

Ukuziphatha kwe-viscosity yesisombululo samanzi se-PDMDAAC kunefuthe elibalulekileyo le-polyelectrolyte. I-viscosity yangaphakathi iyancipha ngokunyuka kwe-concentration yetyuwa eyongeziweyo. Xa i-concentration ye-NaCl ingaphezulu kwe-1 m, utshintsho lwe-viscosity yangaphakathi kunye ne-concentration yetyuwa eyongeziweyo incinci. I-intrinsic viscometer ilinganiswa yi-Ubbelohde viscometer kwisisombululo se-1 M NaCl kwi-30 ℃, kwaye ubunzima be-viscosity obuphakathi bunokufunyanwa ngokwefomula.

Ubunzima bemolekyuli yePDMDAAC bunokufunyanwa kule fomyula ilandelayo, apho i-intrinsic viscosity ilinganiswa kwisisombululo se-1 M NaCl kwi-30 ℃: 407.

UHuang noReichert bafunde ngokulahleka kobunzima bobushushu bePDMDAAC kumanqanaba obushushu ahlukeneyo. Ukulahleka kobunzima obuyi-53.3-130 ℃ kungenxa yokulahleka kwamanzi; Gcina kungatshintshi phakathi kwe-130-200 ℃; Ukulahleka kobunzima kwi-200-310 ℃ yi-41.4%, okubangelwa kukubola kobushushu. Akukho ndawo yokunyibilika efunyenweyo ngexesha lonke lenkqubo yokufudumeza. Ubushushu bokutshintsha kweglasi yePDMDAAC enobunzima beemolekyuli ze-33 kDa yi-8 ℃.

I-PDADMAC ayinabungozi kangako kwi-rainbow trout kune-chitosan (Waller et al. 1993). Nangona kunjalo, i-PDADMAC yonyango lwamanzi inemiqathango kumxholo we-monomer.

I-PDMDAAC eTshayina inomxholo ophezulu we-monomer. I-PDMDAAC yezityalo ezimbini zeekhemikhali ivavanyiwe kwaye kwafunyaniswa ukuba umxholo we-monomer yayiyi-12.5% ​​kunye ne-7.89% (ibalwe njengeqinileyo. Iguqulwe yaba yi-40%, umxholo kwimveliso yayiyi-5.0% kunye ne-3.2%), eyayinkulu kakhulu kune-American Standard ye-0.2% kunye nomgangatho waseYurophu we-0.5%. 380 kwiimveliso ezinomxholo we-monomer ongachazwanga, umxholo we-monomer unokuba phezulu. I-intrinsic viscosity ye-PDMDAAC equlathe i-monomer inikwe ngale fomyula ilandelayo: 411.
