Polydadmac.

Ubusanzwe ikoreshwa nk'umuti wo mu bwoko bwa flocculant ndetse rimwe na rimwe ikanakoreshwa na algicide. Amazina y'ubucuruzi arimo agequat400, St flocculant, pink cure, cat floc, nibindi. PDMDAAC ifite ingaruka nziza hamwe na wscp na poly (2-hydroxypropyl dimethyl ammonium chloride). 413 ikoreshwa muri rusange nk'umuti wo mu bwoko bwa coagulant mu gutunganya amazi mu nganda. Nyuma yo kongeramo alum coagulant, ingano ya coagulant ishobora kuzigamwaho 30%. Urugero, nyuma yo kongeramo 20 mg / L polyaluminium chloride, ongeramo 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride kugira ngo wongere imikorere.

Uburemere bwa molekile ya PDADMAC ubusanzwe ni hagati ya 50000 na 700000, naho uburemere buhinduka bwa 20% by'amazi ni 50-700cps; Uburemere bwa molekile bw'ibicuruzwa bifite polimeri nyinshi bushobora kugera kuri 1000000 kugeza 300000, naho uburemere buhinduka 1000-3000 CPS. Uburemere bw'ibanze ni 80-300ml / g, naho uburemere bukabije bushobora kugera kuri 1440ml / g. Muri rusange, ibi bicuruzwa ni 10-50% by'umuti ufite ubucucike bwa 1.02-1.10 g / ml. Ingano mu mazi yo kunywa igomba kuba munsi ya 10mg / L (Taiwan).

Imyitwarire y'ubushyuhe bw'amazi ya PDMDAAC igira ingaruka zikomeye kuri polyelectrolyte. Ubushyuhe bw'imbere bugabanuka iyo ubwiyongere bw'umunyu wongeweho. Iyo ubwiyongere bwa NaCl burenze metero 1, impinduka y'ubushyuhe bw'imbere hamwe n'ubwiyongere bw'umunyu uba muto cyane. Ubushyuhe bw'imbere bupimwa na viscometer ya Ubbelohde muri 1 M NaCl solution kuri 30 ℃, kandi ubushyuhe bw'impuzandengo y'ubushyuhe bushobora kuboneka hakurikijwe formula.

Uburemere bwa molekile ya PDMDAAC bushobora kuboneka muri formula ikurikira, aho viscosity y'imbere ipimwa muri 1 M NaCl solution kuri 30 ℃: 407.

Huang na Reichert biga ku kugabanuka k'ubushyuhe bwa PDMDAAC mu bushyuhe butandukanye. Kugabanuka k'uburemere kwa 53.3-130 ℃ biterwa no kugabanuka k'amazi; Bika hagati ya 130-200 ℃; Kugabanuka k'uburemere kuri 200-310 ℃ ni 41.4%, biterwa no kubora k'ubushyuhe. Nta gice cyo gushonga cyabonetse mu gihe cyose cyo gushyushya. Ubushyuhe bw'impinduka mu kirahuri cya PDMDAAC ifite uburemere bwa molekile bwa 33 kDa ni 8 ℃.

PDADMAC ntabwo ihumanya cyane inyoni zo mu bwoko bwa rainbow trout kurusha chitosan (Waller et al. 1993). Ariko, PDADMAC yo gutunganya amazi ifite imbogamizi ku ngano ya monomer.

PDMDAAC mu Bushinwa ifite ibipimo byinshi bya monomer. PDMDAAC y’inganda ebyiri z’ibinyabutabire yageragejwe maze isanga ibipimo bya monomer byari 12.5% ​​na 7.89% (byabazwe nk’ibikomeye. Byahinduwe 40%, ibipimo byari mu bicuruzwa byari 5.0% na 3.2%), byari binini cyane kurusha American Standard ya 0.2% n’ibipimo by’i Burayi bya 0.5%. 380 ku bicuruzwa bifite ibipimo bitarasobanuwe bya monomer, ibipimo bya monomer bishobora kuba biri hejuru. Uburemere bw’imbere bwa PDMDAAC irimo monomer butangwa n’uburyo bukurikira: 411.
