A na-ejikarị ya eme ihe dị ka flocculant na mgbe ụfọdụ na-ejikọta ya na algicide. The ahia aha gụnyere agequat400, St flocculant, pink ọgwụgwọ, cat floc, wdg PDMDAAC nwere synergistic mmetụta na wscp na poly (2-hydroxypropyl dimethyl ammonium chloride). A na-ejikarị 413 eme ihe dị ka enyemaka coagulant na ọgwụgwọ mmiri ụlọ ọrụ. Mgbe ịgbakwunye alum coagulant, a ga-echekwa usoro nke coagulant site na 30%. Dịka ọmụmaatụ, mgbe ị gbakwunyere 20 mg / L polyaluminium chloride, tinye 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride iji mụbaa arụmọrụ.

The molekụla arọ nso nke PDADMAC na-emekarị 50000 ka 700000, na ike viscosity nke 20% aqueous ngwọta bụ 50-700cps; The molekụla arọ arọ nke ngwaahịa na elu ogo nke polymerization nwere ike iru 1000000 ka 300000, na ike viscosity bụ 1000-3000 CPS. Viscosity dị n'ime bụ 80-300ml / g, na viscosity dị elu nwere ike iru 1440ml / g. Ngwaahịa bụ n'ozuzu 10-50% ngwọta na a njupụta nke 1.02-1.10 g / ml. A chọrọ usoro onunu ogwu na mmiri ọ drinkingụ drinkingụ ihe na-erughị 10mg / L (Taiwan).

Omume viscosity nke PDMDAAC aqueous solution nwere mmetụta polyelectrolyte dị ịrịba ama. Viscosity dị n'ime na-ebelata site na mmụba nke ntinye nnu agbakwunyere. Mgbe ntinye uche NaCl karịrị 1 m, mgbanwe nke viscosity dị n'ime ya na ntinye nnu agbakwunyere dị ntakịrị. A na-atụ viscosity dị n'ime ahụ site na Ubbelohde viscometer na 1 M NaCl ngwọta na 30 ℃, na viscosity nkezi ịdị arọ molecular nwere ike nweta dịka usoro ahụ siri dị.

Enwere ike nweta ịdị arọ nke PDMDAAC site na usoro a, nke a na-atụ viscosity dị n'ime ya na 1 M NaCl ngwọta na 30 ℃: 407.
