Polydadmac.

Nws ib txwm yog siv raws li flocculant thiab qee zaum ua ke nrog algiced. Cov npe ua lag luam suav nrog lub hnub nyoog muaj hnub nyoog, cov kho mob liab, thiab lwm yam pdmdaac muaj cov nyhuv WSCD thiab Poly (2-hydroxypropyyl ammonium chloride). 413 feem ntau yog siv ua coagulant pab hauv kev kho dej dej. Tom qab ntxiv alum Co coagulant, cov tshuaj ntau ntawm cov coagulant tuaj yeem cawm tau los ntawm 30%. Piv txwv li, tom qab ntxiv 20 mg / l polyaluminium chloride, ntxiv 0.1-0.2 mg / l polydimetlyl ammonium chloride kom ua tau zoo.

Cov khoom hnyav molecular feem ntau ntawm PDAdmac feem ntau yog 50000 txog 700000, thiab cov tshuaj txawv txawv ntawm 20% kev daws teeb meem yog 50-700Cps; Qhov hnyav molecular ntawm cov khoom lag luam nrog cov qib siab ntawm polymerization tuaj yeem ncav cuag 1000000 mus rau 300000, thiab cov hom viscamosed viscosity yog 1000-3000 CPS. Cov viscosity intrinsic yog 80-300ml / g, thiab cov viscosity siab tuaj yeem ncav cuag 1440ml / g. Cov khoom lag luam feem ntau yog 10-50% kev daws teeb meem nrog lub ntom ntom ntawm 1.02-1.10 g / ml. Qhov ntau npaum li cas hauv cov dej haus yuav tsum muaj tsawg dua 10mg / l (taiwan).

Lub viscosity coj tus cwj pwm ntawm PdMdaac aqueous daws muaj qhov tseem ceeb polyelectrolyte nyhuv. Cov viscosity intrinsic kev ua kom tsawg nrog kev nce ntawm cov ntsev ntxiv. Thaum cov nacl concentration yog ntau dua 1 m, qhov hloov pauv ntawm intrinsic viscosity nrog cov ntsev ntxiv yog me me. Cov viscose intrinsic yog ntsuas los ntawm Ubbelohde visicometer hauv 1 m nacl ntawm 30 ℃, thiab lub qhov hnyav ntawm qhov hnyav molecular muaj peev xwm tau raws li cov qauv.

Cov miscular hnyav ntawm PdMdaac tuaj yeem tau los ntawm cov qauv hauv qab no, nyob rau hauv uas cov viscinscicic yog ntsuas hauv 1 m nacl daws ntawm 30 ℃: 407.

Huang thiab repichert kawm cov thermal ceeb thawj poob ntawm pdmdaac hauv qhov kub thiab txias. 53.3-130 ℃ Lub cev yuag yog vim dej poob; Khaws tsis hloov dua li ntawm 130-200 ℃; Qhov hnyav poob ntawm 200-310 ℃ yog 41.4%, uas yog vim yog cov thermal decomposition. Tsis muaj melting point tau pom thaum lub caij ua cua sov tag nrho. Lub iav hloov kub ntawm pdmdaac nrog molecular hnyav ntawm 33 KDA yog 8 ℃.

PDAdmac yog tsawg dua lom rau zaj sawv tshaj li Chitosan (phab ntsa et al. 1993). Txawm li cas los xij, PDAdmac rau kev kho dej muaj cov kev txwv rau cov ntsiab lus monomer.

Pdmdaac hauv Suav teb muaj siab monomer cov ntsiab lus. Lub PdMdaac ntawm ob cov nroj tsuag tshuaj tau raug kuaj thiab pom tias cov ntsiab lus monomer tau muaj 12,5% thiab 3.2%), uas tau loj dua li Asmeskas Txheem ntawm 0.2% thiab European txheem ntawm 0.5%. 380 rau cov khoom lag luam nrog cov ntsiab lus tsis txaus ntseeg, cov ntsiab lus monomer yuav siab dua. Cov viscdica intrinsic ntawm PdMdaac uas muaj los ntawm cov qauv hauv qab no: 411.
