Hangata e sebelisoa e le flocculant 'me ka linako tse ling e kopantsoe le algicide. Mabitso a khoebo a kenyelletsa agequat400, St flocculant, phekolo e pinki, cat floc, joalo-joalo PDMDAAC e na le phello ea synergistic le wscp le poly (2-hydroxypropyl dimethyl ammonium chloride). 413 hangata e sebelisoa e le thuso ea coagulant kalafong ea metsi ea indasteri. Kamora ho eketsa alum coagulant, tekanyo ea coagulant e ka bolokeha ka 30%. Ka mohlala, ka mor'a ho eketsa 20 mg / L polyaluminium chloride, eketsa 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride ho eketsa katleho.

Mefuta ea boima ba molek'hule ea PDADMAC hangata ke 50000 ho 700000, 'me viscosity e matla ea 20% ea tharollo ea metsi ke 50-700cps; Boima ba limolek'hule tsa lihlahisoa tse nang le polymerization e phahameng li ka fihla ho 1000000 ho isa ho 300000, 'me viscosity e matla ke 1000-3000 CPS. The intrinsic viscosity ke 80-300ml / g, 'me viscosity e phahameng e ka fihla ho 1440ml / g. Sehlahisoa ka kakaretso ke 10-50% tharollo le segokanyipalo sa 1.02-1.10 g / ml. Tekanyetso ea metsi a nooang e tlameha ho ba ka tlase ho 10mg / L (Taiwan).

Boitšoaro ba viscosity ea tharollo ea metsi ea PDMDAAC e na le phello e kholo ea polyelectrolyte. The intrinsic viscosity ea fokotseha ka ho eketseha ha letsoai le eketsehileng. Ha mahloriso a NaCl a le kholo ho feta 1 m, phetoho ea intrinsic viscosity e nang le letsoai le ekelitsoeng e batla e le nyenyane. The intrinsic viscosity e lekantsoe ke Ubbelohde viscometer ka 1 M NaCl tharollo ho 30 ℃, 'me viscosity karolelano boima ba molek'hule e ka fumanoa ho ea ka foromo.

Boima ba limolek'hule tsa PDMDAAC bo ka fumanoa ho latela foromo e latelang, eo ho eona viscosity ea kahare e lekantsoeng ka tharollo ea 1 M NaCl ho 30 ℃: 407.

Huang le Reichert ba ithutile ho theola boima ba 'mele ba PDMDAAC maemong a fapaneng a mocheso. 53.3-130 ℃ tahlehelo ea boima ba 'mele ka lebaka la tahlehelo ea metsi; Boloka e sa fetohe pakeng tsa 130-200 ℃; Ho theola boima ba 'mele ho 200-310 ℃ ke 41.4%, e leng ka lebaka la ho senyeha ha mocheso. Ha ho sebaka sa ho qhibiliha se ileng sa fumanoa nakong eohle ea ho futhumatsa. Mocheso oa phetoho ea khalase ea PDMDAAC e nang le boima ba molek'hule ea 33 kDa ke 8 ℃.

PDADAC ha e na chefo e nyane ho trout ea mookoli ho feta chitosan (Waller et al. 1993). Leha ho le joalo, PDADAC bakeng sa kalafo ea metsi e na le lithibelo holim'a litaba tsa monomer.

PDMDAAC naheng ea China e na le litaba tse phahameng tsa monomer. PDMDAAC ea limela tse peli tsa lik'hemik'hale e ile ea lekoa 'me ea fumana hore litaba tsa monomer li ne li le 12.5% ​​le 7.89% (e ne e baloa e le e tiileng. E fetotsoe ho 40%, lihlahisoa tsa sehlahisoa e ne e le 5.0% le 3.2%), e neng e le kholoanyane ho feta Amerika. Tekanyetso ea 0.2% le maemo a Europe a 0.5%. 380 bakeng sa lihlahisoa tse nang le litaba tsa monoma tse sa hlalosoang, litaba tsa monoma li kanna tsa ba holimo. The intrinsic viscosity ea PDMDAAC e nang le monoma e fanoa ka foromo e latelang: 411.
