Polydadmac.

He mea whakamahi noa hei whakapūkara wai, ā, i ētahi wā ka honoa ki te algicide. Ko ngā ingoa hokohoko ko agequat400, St flocculant, pink cure, cat floc, me ētahi atu. He pānga tahi te PDMDAAC me te wscp me te poly (2-hydroxypropyl dimethyl ammonium chloride). Ko te 413 te mea e whakamahia whānuitia ana hei āwhina i te whakapūkara wai i roto i te maimoatanga wai ahumahi. I muri i te tāpiri i te whakapūkara konumohe, ka taea te penapena i te horopeta o te whakapūkara mā te 30%. Hei tauira, i muri i te tāpiri i te 20 mg/L polyaluminium chloride, tāpirihia te 0.1-0.2 mg/L Polydimethyldiallyl ammonium chloride hei whakanui ake i te whai huatanga.

Ko te taumaha ngota o te PDADMAC he 50000 ki te 700000 te tikanga, ā, ko te matotoru hihiri o te 20% o te wairewa he 50-700cps; Ko te taumaha ngota o ngā hua he nui te polymerization ka eke ki te 1000000 ki te 300000, ā, ko te matotoru hihiri he 1000-3000 CPS. Ko te matotoru ā-roto he 80-300ml/g, ā, ko te matotoru teitei ka eke ki te 1440ml/g. Ko te hua he 10-50% o te wairewa me te mātotoru o te 1.02-1.10 g/ml. Ko te horopeta i roto i te wai inu me iti iho i te 10mg/L (Taiwan).

He nui te pānga o te polyelectrolyte o te wairewa PDMDAAC. Ka heke te matotoru o roto i te pikinga o te kukū tote tāpiri. Ina nui ake te kukū NaCl i te 1 m, he iti noa te huringa o te matotoru o roto me te kukū tote tāpiri. Ka inehia te matotoru o roto mā te whakamahi i te inenga Ubbelohde viscometer i roto i te wairewa 1 M NaCl i te 30 ℃, ā, ka taea te whiwhi i te taumaha ngota ngota toharite o te matotoru e ai ki te tātai.

Ka taea te tiki i te taumaha ngota o te PDMDAAC mai i te tātai e whai ake nei, e inehia ai te matotoru ā-roto i roto i te otinga 1 M NaCl i te 30 ℃: 407.

I rangahau a Huang rāua ko Reichert i te ngaronga taumaha wera o te PDMDAAC i ngā awhe pāmahana rerekē. Ko te ngaronga taumaha 53.3-130 ℃ nā te ngaronga wai; Kaua e whakarerekētia i waenga i te 130-200 ℃; Ko te ngaronga taumaha i te 200-310 ℃ he 41.4%, nā te pirau wera. Kāore i kitea he ira rewa i te wā o te tukanga whakamahana katoa. Ko te pāmahana whakawhiti karāhe o te PDMDAAC me te taumaha ngota o te 33 kDa he 8 ℃.

He iti ake te paitini o te PDADMAC ki te ika taraute āniwaniwa i te chitosan (Waller et al. 1993). Heoi, he herenga kei te PDADMAC mō te maimoatanga wai mō te ihirangi monomer.

He nui te ihirangi monomer o te PDMDAAC i Haina. I whakamatautauria te PDMDAAC o ngā tipu matū e rua, ā, i kitea ko te ihirangi monomer he 12.5% ​​me te 7.89% (i tatauhia hei totoka. I hurihia ki te 40%, ko te ihirangi i roto i te hua he 5.0% me te 3.2%), he nui ake i te Paerewa Amerika o te 0.2% me te paerewa Pākehā o te 0.5%. 380 mō ngā hua he ihirangi monomer kāore i tohua, tera pea he teitei ake te ihirangi monomer. Ko te matotoru ā-roto o te monomer kei roto i te PDMDAAC ka hoatuhia e te tātai e whai ake nei: 411.
