Polydadmac.

I te nuinga o te wa ka whakamahia hei pupuhi me etahi wa ka honoa ki te algicide.Ko nga ingoa hokohoko ko te agequat400, St flocculant, te rongoa mawhero, te ngeru ngeru, me etahi atu. Ko te PDMDAAC he mahi synergistic me te wscp me te poly (2-hydroxypropyl dimethyl ammonium chloride).Ko te 413 te nuinga ka whakamahia hei awhina coagulant i roto i te maimoatanga wai ahumahi.Whai muri i te taapiri i te coagulant alum, ka taea te penapena i te inenga o te coagulant e 30%.Hei tauira, i muri i te taapiri i te 20 mg / L polyaluminium chloride, taapirihia te 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride hei whakanui ake i te pai.

Ko te awhe o te taumaha ngota o te PDADMAC ko te nuinga o te 50000 ki te 700000, a ko te 50-700cps te kaha o te kaha o te 20% wairewa wai;Ko te taumaha ngota o nga hua me te nui o te polymerization ka taea te tae ki te 1000000 ki te 300000, a ko te 1000-3000 CPS te pokey hihiri.Ko 80-300ml / g te pokey o roto, a ka taea e te pokey teitei tae 1440ml / g.Ko te hua te tikanga 10-50% otinga me te kiato o 1.02-1.10 g / ml.Ko te inenga o te wai inu me iti iho i te 10mg / L (Taiwan).

Ko te whanonga pokey o te wairewa wai PDMDAAC he painga polyelectrolyte nui.Ka heke te pokeytanga o roto i te pikinga o te kukū o te tote.Ina nui ake te kukū o te NaCl i te 1 m, he iti noa te huringa o te pokeytanga o roto me te kukū tote taapiri.Ka inehia te viscosity intrinsic e Ubbelohde viscometer i roto i te 1 M NaCl solution i te 30 ℃, a ka taea te whiwhi i te taumaha ngota ngota toharite viscosity i runga i te tauira.

Ko te taumaha ngota o te PDMDAAC ka taea te tiki mai i te tauira e whai ake nei, i ine ai te viscosity intrinsic i roto i te otinga 1 M NaCl i te 30 ℃: 407.

I ako a Huang raua ko Reichert i te mate taimaha waiariki o PDMDAAC i roto i nga awhe pāmahana rereke.53.3-130 ℃ te mate taimaha na te mate wai;Kaua e huri i waenga i te 130-200 ℃;Ko te mate taimaha i te 200-310 ℃ he 41.4%, na te waiariki pirau.Karekau he ira whakarewa i kitea i te wa katoa o te whakamahana.Ko te pāmahana whakawhiti karaihe o PDMDAAC me te taumaha ngota o te 33 kDa he 8 ℃.

He iti ake te paitini o te PDADMAC ki te taraute aniwaniwa i te chitosan (Waller et al. 1993).Engari, ko te PDADMAC mo te maimoatanga wai he here mo te ihirangi monomer.

Ko te PDMDAAC i Haina he nui te ihirangi monomer.I whakamatauria te PDMDAAC o nga tipu matū e rua, ka kitea ko nga ihirangi monomer he 12.5% ​​me te 7.89% (kua tatauhia hei totoka. I hurihia ki te 40%, ko te ihirangi i roto i te hua ko 5.0% me te 3.2%), he nui ake i te Amerika. Paerewa 0.2% me te paerewa Pakeha 0.5%.380 mo nga hua me te ihirangi monomer kore i tohua, ka nui ake pea te ihirangi monomer.Ko te viscosity o roto o te PDMDAAC kei roto i te monomer ka hoatu e te tauira e whai ake nei: 411.
