Polydadmac.

Ubusanzwe ikoreshwa nka flocculant kandi rimwe na rimwe igahuzwa na algicide.Amazina yubucuruzi arimo agequat400, St flocculant, umutuku wijimye, injangwe y’injangwe, nibindi PDMDAAC igira ingaruka zifatika hamwe na wscp na poly (2-hydroxypropyl dimethyl ammonium chloride).413 muri rusange ikoreshwa nkimfashanyo ya coagulant mugutunganya amazi yinganda.Nyuma yo kongeramo alum coagulant, dosiye ya coagulant irashobora gukizwa na 30%.Kurugero, nyuma yo kongeramo 20 mg / L polyaluminium chloride, ongeramo 0.1-0.2 mg / L Polydimethyldallyl ammonium chloride kugirango wongere imikorere.

Uburemere bwa molekuline ya PDADMAC mubusanzwe ni 50000 kugeza 700000, naho viscosity ya 20% yumuti wamazi ni 50-700cps;Uburemere bwa molekuline yibicuruzwa bifite urwego rwo hejuru rwa polymerisiyasi birashobora kugera 1000000 kugeza 300000, naho viscosity dinamike ni 1000-3000 CPS.Ubukonje bwimbere ni 80-300ml / g, kandi ubukonje bwinshi bushobora kugera kuri 1440ml / g.Igicuruzwa muri rusange ni 10-50% igisubizo hamwe nubucucike bwa 1.02-1.10 g / ml.Igipimo cyamazi yo kunywa kirasabwa kuba munsi ya 10mg / L (Tayiwani).

Imyitwarire ya viscosity ya PDMDAAC igisubizo cyamazi gifite ingaruka zikomeye za polyelectrolyte.Ubwiza bwimbere bugabanuka hamwe no kwiyongera kwumunyu wongeyeho.Iyo intumbero ya NaCl irenze m 1, ihinduka ryimbere yimbere hamwe niyongewemo umunyu ni muto.Ubusembwa bwimbere bupimwa na viscometer ya Ubbelohde muri 1 M NaCl igisubizo kuri 30 and, kandi uburemere bwikigereranyo cya molekile irashobora kuboneka ukurikije formulaire.

Uburemere bwa molekuline ya PDMDAAC burashobora kuboneka muburyo bukurikira, aho ubwiza bwimbere bupimirwa mumuti 1 M NaCl kuri 30 ℃: 407.

Huang na Reichert bize ubushakashatsi bwo kugabanya ubushyuhe bwa PDMDAAC mubushyuhe butandukanye.53.3-130 loss gutakaza ibiro biterwa no gutakaza amazi;Komeza guhinduka hagati ya 130-200 ℃;Kugabanuka ibiro 200-310 ℃ ni 41.4%, biterwa no kubora.Nta kintu cyo gushonga cyabonetse mugihe cyose cyo gushyushya.Ubushyuhe bwikirahure bwa PDMDAAC nuburemere bwa molekuline ya 33 kDa ni 8 ℃.

PDADMAC ntabwo ifite uburozi kuri umukororombya kurusha chitosan (Waller et 1993.).Ariko, PDADMAC yo gutunganya amazi ifite imipaka kubintu bya monomer.

PDMDAAC mubushinwa ifite monomer nyinshi.PDMDAAC y’ibiti bibiri by’imiti yarageragejwe isanga ibirimo monomer byari 12.5% ​​na 7.89% (bibarwa nkibikomeye. Byahinduwe kuri 40%, ibikubiye mubicuruzwa byari 5.0% na 3.2%), byari binini cyane kurenza umunyamerika Igipimo cya 0.2% hamwe nu Burayi bwa 0.5%.380 kubicuruzwa bifite monomer idasobanutse neza, ibirimo monomer birashobora kuba hejuru.Ubwiza bwimbere bwa PDMDAAC burimo monomer butangwa na formula ikurikira: 411.
