Poly (dimethyldiallylammonium chloride), feem ntau hu ua polyDADMAC lossis polyDDA, tau dhau los ua kev ua si hloov pauv polymer hauv kev tshawb fawb thiab thev naus laus zis niaj hnub no.Qhov no ntau yam polymer yog dav siv nyob rau hauv ntau yam lag luam, los ntawm kev kho dej khib nyiab mus rau cov tshuaj pleev ib ce thiab cov khoom tu tus kheej.
Ib qho ntawm cov ntawv thov tseem ceeb ntawm polyDADMAC yog cov coagulants rau kev kho dej.Lub polymer cov khoom zoo quaternary ammonium pawg khi nrog cov khoom tsis zoo hauv dej, tsim cov khoom loj thiab hnyav dua uas tuaj yeem tshem tau yooj yim los ntawm sedimentation lossis pom.Qhov no ua rau nws muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo rau cov tshuaj coagulants xws li alum thiab ferric chloride.
Ntxiv nrog rau kev kho dej, polyDADMAC tseem pom daim ntawv thov hauv kev lag luam ntawv, qhov twg nws yog siv los ua cov kev pab khaws cia thiab qhuav-lub zog tus neeg sawv cev los txhim kho cov ntawv zoo thiab txo cov khoom siv tshuaj papermaking.Lub polymer tus nqi cationic ua rau nws muaj txiaj ntsig ntawm kev khi nrog cov ntoo tsis zoo thiab cov khoom ntim rau hauv daim ntawv pulp, txhim kho daim ntawv lub zog thiab tuav cov khoom ntim.
PolyDADMAC kuj tseem siv rau hauv kev saib xyuas tus kheej thiab kev lag luam tshuaj pleev ib ce ua tus neeg ua haujlwm txias thiab emulsifier.Nws cov nqi cationic ua rau nws ua haujlwm zoo ntawm kev khi nrog cov plaub hau thiab tawv nqaij tsis zoo, txhim kho kev ntxhib los mos thiab kev xav ntawm cov khoom xws li tshuaj zawv plaub hau, txias, thiab tshuaj pleev.
Raws li tus thawj coj hauvpolyDADMAC ntau lawm, peb lub tuam txhab tau cog lus los muab cov khoom lag luam zoo thiab kev pabcuam rau peb cov neeg siv khoom thoob plaws kev lag luam.Peb nkag siab qhov tseem ceeb ntawm kev txhim khu kev qha thiab ua tau zoo coagulants hauv kev kho dej thiab siv zog los muab cov kev daws teeb meem zoo uas ua tau raws li cov kev xav tau tshwj xeeb ntawm peb cov neeg siv khoom.Peb pab pawg kws tshaj lij tseem niaj hnub tshawb nrhiav cov ntawv thov tshiab ntawm polyDADMAC hauv kev lag luam tawm tshiab, kom ntseeg tau tias peb nyob ntawm qhov ua ntej ntawm kev tsim kho tshiab.
Hauv kev xaus, ntau yam PDADMAC polymer yog hloov pauv kev lag luam nrog nws cov kev siv ntau yam, suav nrog cov coagulants rau kev kho dej, cov neeg ua haujlwm khaws cia hauv kev lag luam ntawv, thiab cov neeg ua haujlwm txias hauv cov khoom tu tus kheej.Raws li qhov kev thov rau cov polymer no txuas ntxiv mus, peb zoo siab los ua tus thawj coj ntawm nws txoj kev loj hlob thiab tos ntsoov yuav tshawb nrhiav cov ntawv thov tshiab dua yav tom ntej.
