Polydadmac.

Nthawi zambiri amagwiritsidwa ntchito ngati flocculant ndipo nthawi zina amaphatikizidwa ndi algicide.Mayina amalonda akuphatikizapo agequat400, St flocculant, mankhwala apinki, mphaka wa floc, etc. PDMDAAC ili ndi synergistic effect ndi wscp ndi poly (2-hydroxypropyl dimethyl ammonium chloride).413 nthawi zambiri imagwiritsidwa ntchito ngati coagulant yothandizira pakuchiritsa madzi m'mafakitale.Mukawonjezera alum coagulant, mlingo wa coagulant ukhoza kupulumutsidwa ndi 30%.Mwachitsanzo, mutatha kuwonjezera 20 mg / L polyaluminium chloride, onjezerani 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride kuti muwonjezere mphamvu.

Maselo olemera a PDADAC nthawi zambiri amakhala 50000 mpaka 700000, ndipo kukhuthala kwamphamvu kwa 20% yamadzimadzi ndi 50-700cps;Kulemera kwa maselo azinthu okhala ndi digiri yayikulu ya polymerization 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.The mankhwala zambiri 10-50% njira ndi kachulukidwe wa 1.02-1.10 g / ml.Mlingo wamadzi akumwa uyenera kukhala wochepera 10mg / L (Taiwan).

Makhalidwe a mamasukidwe akayendedwe a PDMDAAC amadzimadzi amadzimadzi ali ndi mphamvu ya polyelectrolyte.Kukhuthala kwamkati kumachepa ndi kuchuluka kwa mchere wowonjezera.Pamene ndende ya NaCl ili yaikulu kuposa 1 m, kusintha kwa kukhuthala kwamkati ndi mchere wowonjezera kumakhala kochepa.Kukhuthala kwamkati kumayesedwa ndi Ubbelohde viscometer mu 1 M NaCl yankho pa 30 ℃, ndipo kukhuthala kwapakati pa molekyulu kumatha kupezeka molingana ndi chilinganizo.

Kulemera kwa molekyulu ya PDMDAAC kumatha kupezedwa kuchokera ku formula iyi, momwe kukhuthala kwamkati kumayesedwa mu 1 M NaCl yankho pa 30 ℃: 407.

Huang ndi Reichert adaphunzira kuwonda kwamafuta kwa PDMDAAC mumitundu yosiyanasiyana ya kutentha.53.3-130 ℃ kuwonda chifukwa cha kutaya madzi;Sungani zosasinthika pakati pa 130-200 ℃;Kutaya thupi pa 200-310 ℃ ndi 41.4%, chifukwa cha kuwonongeka kwa matenthedwe.Palibe kusungunuka komwe kunapezeka panthawi yonseyi.The galasi kusintha kutentha kwa PDMDAAC ndi molecular kulemera 33 kDa ndi 8 ℃.

PDADMAC ilibe poizoni ku trout kuposa chitosan (Waller et al. 1993).Komabe, PDADAC yochiza madzi ili ndi zoletsa pazokhutira za monomer.

PDMDAAC ku China ili ndi zinthu zambiri za monomer.PDMDAAC ya zomera ziwiri za mankhwala inayesedwa ndipo inapeza kuti zomwe zili mu monomer zinali 12.5% ​​ndi 7.89% (zowerengedwa ngati zolimba. Zotembenuzidwa ku 40%, zomwe zili mu mankhwalawa zinali 5.0% ndi 3.2%), zomwe zinali zazikulu kwambiri kuposa American. Muyezo wa 0.2% ndi muyezo waku Europe wa 0.5%.380 pazogulitsa zomwe zili ndi ma monomer osadziwika, zomwe zili ndi monomer zitha kukhala zapamwamba.Kuwonekera kwamkati kwa PDMDAAC yokhala ndi monomer kumaperekedwa ndi njira iyi: 411.
