Polydadmac.

Hoʻohana maʻamau ia e like me ka flocculant a i kekahi manawa hui pū me ka algicide.Aia nā inoa kālepa i agequat400, St flocculant, pink cure, cat floc, etc. He hopena synergistic ka PDMDAAC me ka wscp a me ka poly (2-hydroxypropyl dimethyl ammonium chloride).Hoʻohana pinepine ʻia ʻo 413 ma ke ʻano he kōkua coagulant i ka mālama wai ʻoihana.Ma hope o ka hoʻohui ʻana i ka coagulant alum, hiki ke mālama ʻia ke ʻano o ka coagulant e 30%.No ka laʻana, ma hope o ka hoʻohui ʻana i ka 20 mg / L polyaluminium chloride, e hoʻohui i ka 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride e hoʻonui i ka pono.

ʻO ka nui o ke kaumaha molecular o PDADMAC maʻamau 50000 a 700000, a ʻo ka viscosity ikaika o 20% aqueous solution he 50-700cps;ʻO ke kaumaha molecular o nā huahana me ke kiʻekiʻe o ka polymerization hiki ke hiki i 1000000 a 300000, a ʻo ka viscosity ikaika ʻo 1000-3000 CPS.ʻO ka viscosity intrinsic he 80-300ml / g, a hiki i ka viscosity kiʻekiʻe ke hiki i 1440ml / g.ʻO ka huahana maʻamau ka hopena 10-50% me ka nui o 1.02-1.10 g / ml.Pono ʻia ka nui o ka wai inu ma lalo o 10mg / L (Taiwan).

He hopena polyelectrolyte koʻikoʻi ka hana viscosity o ka PDMDAAC aqueous solution.Ke emi nei ka viscosity intrinsic me ka hoʻonui ʻia o ka paʻakai i hoʻohui ʻia.Ke ʻoi aku ka nui o ka NaCl ma mua o 1 m, ʻoi aku ka liʻiliʻi o ka hoʻololi ʻana o ka viscosity intrinsic me ka paʻakai i hoʻohui ʻia.Ua ana ʻia ka viscosity intrinsic e Ubbelohde viscometer i 1 M NaCl solution ma 30 ℃, a hiki ke loaʻa ka viscosity average molecular weight e like me ke kumu.

Hiki ke kiʻi ʻia ke kaumaha molekala o PDMDAAC mai kēia ʻano kumu, kahi e ana ʻia ai ka viscosity intrinsic ma 1 M NaCl solution ma 30 ℃: 407.

Ua aʻo ʻo Huang lāua ʻo Reichert i ka pohō kaumaha wela o PDMDAAC ma nā pae wela like ʻole.ʻO 53.3-130 ℃ ka pohō kaumaha ma muli o ka nalowale wai;E hoʻololi ʻole ma waena o 130-200 ℃;ʻO ka poho kaumaha ma 200-310 ℃ he 41.4%, ma muli o ka hoʻoheheʻe wela.ʻAʻohe wahi hoʻoheheʻe i ʻike ʻia i ka wā o ka hana hoʻomehana holoʻokoʻa.ʻO ka mahana hoʻololi aniani o PDMDAAC me ke kaumaha molekala o 33 kDa he 8 ℃.

ʻO ka PDADMAC ka liʻiliʻi o ka ʻawaʻawa i ke ānuenue trout ma mua o ka chitosan (Waller et al. 1993).Eia nō naʻe, ʻo ka PDADMAC no ka mālama ʻana i ka wai he mau palena i ka ʻike monomer.

PDMDAAC ma Kina he kiʻekiʻe monomer maʻiʻo.Ua ho'āʻoʻia ka PDMDAAC o nā mea kanu kemikaʻelua a uaʻikeʻia he 12.5% ​​a me 7.89% nā mea monomer (heluʻia e like me ka paʻa. Ua hoʻololiʻia i 40%,ʻo ka mea i loko o ka huahana he 5.0% a me 3.2%), iʻoi aku ka nui ma mua o kaʻAmelika. ʻO ke kūlana o 0.2% a me ka maʻamau ʻEulopa o 0.5%.380 no nā huahana me ka ʻike monomer i ʻike ʻole ʻia, ʻoi aku ka kiʻekiʻe o ka ʻike monomer.Hāʻawi ʻia ka viscosity intrinsic o ka PDMDAAC i loko o ka monomer e kēia ʻano: 411.
