Polydadmac.

Kawirikawiri imagwiritsidwa ntchito ngati flocculant ndipo nthawi zina imaphatikizidwa ndi algicide. Mayina amalonda ndi monga agequat400, St flocculant, pinki cure, cat floc, ndi zina zotero. PDMDAAC imakhala ndi mphamvu yogwirizana ndi wscp ndi poly (2-hydroxypropyl dimethyl ammonium chloride). 413 nthawi zambiri imagwiritsidwa ntchito ngati coagulant pochiza madzi m'mafakitale. Mukawonjezera alum coagulant, mlingo wa coagulant ukhoza kusungidwa ndi 30%. Mwachitsanzo, mukawonjezera 20 mg / L polyaluminium chloride, onjezani 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride kuti muwonjezere magwiridwe antchito.

Kulemera kwa mamolekyulu a PDADMAC nthawi zambiri kumakhala pakati pa 50000 ndi 700000, ndipo kukhuthala kwamphamvu kwa yankho lamadzimadzi la 20% ndi 50-700cps; Kulemera kwa mamolekyulu azinthu zomwe zili ndi polymerization yayikulu kumatha kufika 1000000 mpaka 300000, ndipo kukhuthala kwamphamvu ndi 1000-3000 CPS. Kukhuthala kwamkati ndi 80-300ml / g, ndipo kukhuthala kwakukulu kumatha kufika 1440ml / g. Chogulitsachi nthawi zambiri chimakhala yankho la 10-50% ndi kuchuluka kwa 1.02-1.10 g / ml. Mlingo wamadzi akumwa umafunika kukhala wochepera 10mg / L (Taiwan).

Kachitidwe ka kukhuthala kwa yankho lamadzi la PDMDAAC kamakhala ndi mphamvu yayikulu ya polyelectrolyte. Kukhuthala kwa mkati kumachepa ndi kuwonjezeka kwa kuchuluka kwa mchere wowonjezera. Pamene kuchuluka kwa NaCl kuli koposa 1 m, kusintha kwa kukhuthala kwa mkati ndi kuchuluka kwa mchere wowonjezera kumakhala kochepa. Kukhuthala kwa mkati kumayesedwa ndi Ubbelohde viscometer mu yankho la 1 M NaCl pa 30 ℃, ndipo kulemera kwapakati kwa mamolekyulu kungapezeke malinga ndi fomula.

Kulemera kwa mamolekyulu a PDMDAAC kungapezeke kuchokera ku fomula iyi, momwe kukhuthala kwamkati kumayesedwa mu yankho la 1 M NaCl pa 30 ℃: 407.

Huang ndi Reichert adaphunzira za kutayika kwa kulemera kwa PDMDAAC m'malo osiyanasiyana otentha. Kuchepa kwa kulemera kwa 53.3-130 ℃ kumachitika chifukwa cha kutayika kwa madzi; Sungani mosasunthika pakati pa 130-200 ℃; Kuchepa kwa kulemera pa 200-310 ℃ ndi 41.4%, komwe kumachitika chifukwa cha kuwonongeka kwa kutentha. Palibe malo osungunuka omwe adapezeka panthawi yonse yotenthetsera. Kutentha kwa kusintha kwa galasi kwa PDMDAAC yokhala ndi kulemera kwa mamolekyulu a 33 kDa ndi 8 ℃.

PDADMAC ndi yoopsa pang'ono kwa nsomba ya rainbow trout kuposa chitosan (Waller et al. 1993). Komabe, PDADMAC yochizira madzi ili ndi zoletsa pa kuchuluka kwa monomer.

PDMDAAC ku China ili ndi kuchuluka kwa monomer. PDMDAAC ya mafakitale awiri a mankhwala idayesedwa ndipo idapezeka kuti kuchuluka kwa monomer kunali 12.5% ​​ndi 7.89% (kuwerengedwa ngati kolimba. Posinthidwa kukhala 40%, kuchuluka kwa mankhwalawa kunali 5.0% ndi 3.2%), komwe kunali kwakukulu kwambiri kuposa American Standard ya 0.2% ndi European standard ya 0.5%. 380 pazinthu zomwe zili ndi monomer yosadziwika, kuchuluka kwa monomer kungakhale kokwera. Kukhuthala kwamkati kwa PDMDAAC yokhala ndi monomer kumaperekedwa ndi njira iyi: 411.
