Polydadmac.

Nws feem ntau yog siv los ua flocculant thiab qee zaum ua ke nrog algicide.Cov npe lag luam muaj xws li agequat400, St flocculant, liab kho, miv floc, thiab lwm yam. PDMDAAC muaj cov nyhuv synergistic nrog wscp thiab poly (2-hydroxypropyl dimethyl ammonium chloride).413 feem ntau yog siv los ua coagulant pab hauv kev kho dej.Tom qab ntxiv alum coagulant, qhov ntau npaum ntawm coagulant tuaj yeem txuag tau 30%.Piv txwv li, tom qab ntxiv 20 mg / L polyaluminium chloride, ntxiv 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride kom ua tau zoo.

Qhov hnyav molecular ntawm PDADMAC feem ntau yog 50000 txog 700000, thiab dynamic viscosity ntawm 20% aqueous tov yog 50-700cps;Qhov hnyav molecular ntawm cov khoom nrog qib siab ntawm polymerization tuaj yeem ncav cuag 1000000 txog 300000, thiab dynamic viscosity yog 1000-3000 CPS.Intrinsic viscosity yog 80-300ml / g, thiab viscosity siab tuaj yeem ncav cuag 1440ml / g.Cov khoom lag luam feem ntau yog 10-50% daws nrog qhov ceev ntawm 1.02-1.10 g / ml.Qhov ntau npaum li cas hauv cov dej haus yuav tsum tsawg dua 10mg / L (Taiwan).

Tus cwj pwm viscosity ntawm PDMDAAC aqueous tov muaj cov nyhuv polyelectrolyte tseem ceeb.Lub intrinsic viscosity txo nrog qhov nce ntxiv ntsev concentration.Thaum NaCl concentration ntau dua 1 m, qhov kev hloov ntawm cov viscosity intrinsic nrog cov ntsev ntxiv yog me me.Intrinsic viscosity yog ntsuas los ntawm Ubbelohde viscometer hauv 1 M NaCl tov ntawm 30 ℃, thiab viscosity nruab nrab molecular hnyav tuaj yeem tau raws li cov qauv.

Qhov hnyav molecular ntawm PDMDAAC tuaj yeem tau txais los ntawm cov qauv hauv qab no, uas qhov viscosity intrinsic ntsuas hauv 1 M NaCl tov ntawm 30 ℃: 407.

Huang thiab Reichert tau kawm txog cov thermal poob ntawm PDMDAAC nyob rau hauv ntau qhov kub thiab txias.53.3-130 ℃ poob phaus yog vim dej poob;Khaws tsis hloov ntawm 130-200 ℃;Qhov hnyav poob ntawm 200-310 ℃ yog 41.4%, uas yog vim thermal decomposition.Tsis muaj cov ntsiab lus melting tau pom thaum lub sij hawm tag nrho cov txheej txheem cua sov.Lub iav hloov kub ntawm PDMDAAC nrog molecular hnyav ntawm 33 kDa yog 8 ℃.

PDADMAC tsis tshua muaj tshuaj lom rau zaj sawv trout tshaj li chitosan (Waller li al. 1993).Txawm li cas los xij, PDADMAC rau kev kho dej muaj kev txwv rau cov ntsiab lus monomer.

PDMDAAC hauv Suav teb muaj cov ntsiab lus siab monomer.Lub PDMDAAC ntawm ob cov tshuaj nroj tsuag tau sim thiab pom tias cov ntsiab lus monomer yog 12.5% ​​thiab 7.89% (xws li cov khoom. Hloov mus rau 40%, cov ntsiab lus hauv cov khoom yog 5.0% thiab 3.2%), uas yog ntau dua li Asmeskas. Tus qauv ntawm 0.2% thiab European tus qauv ntawm 0.5%.380 rau cov khoom uas tsis muaj cov ntsiab lus monomer, cov ntsiab lus monomer yuav siab dua.Lub intrinsic viscosity ntawm PDMDAAC muaj monomer yog muab los ntawm cov mis hauv qab no: 411.
