PolyDADMAC, ib lub npe tshuaj lom neeg uas zoo li nyuaj thiab paub tsis meej, qhov tseeb yog ib feem tseem ceeb ntawm peb lub neej txhua hnub. Ua tus sawv cev ntawm cov tshuaj polymer, PolyDADMAC siv dav hauv ntau qhov chaw. Txawm li cas los xij, koj puas nkag siab txog nws cov khoom siv tshuaj lom neeg, cov khoom lag luam, thiab kev lom? Tom ntej no, tsab xov xwm no yuav muab kev nkag siab tob rau koj txog PolyDADMAC.
Cov khoom siv tshuaj lom neeg ntawm PolyDADMAC txiav txim siab nws cov khoom tshwj xeeb. Raws li ib qho cationic polyelectrolyte muaj zog, PolyDADMAC yog muab los ua cov kua dej tsis muaj xim rau lub teeb daj, lossis qee zaum dawb pearls. Nws cov khoom muaj kev nyab xeeb thiab tsis muaj tshuaj lom ua rau nws siv dav hauv cov teb xws li kev kho dej, textiles, papermaking, thiab cov teb roj. Tsis tas li ntawd, PolyDADMAC yooj yim yaj hauv dej, tsis kub hnyiab, muaj kev sib koom ua ke zoo, kev ruaj khov hydrolytic zoo, tsis rhiab rau kev hloov pH, thiab muaj cov khoom zoo heev xws li kev tiv thaiv chlorine. Nws feem ntau yog siv ua flocculant thiab qee zaum dosed nrog algaecides. Nws tau tshaj tawm tias PDMDAAC muaj kev cuam tshuam synergistic nrog WSCP thiab poly-2-hydroxypropyl dimethylammonium chloride.
PolyDADMAC pib ua haujlwm li cas?
PolyDADMAC muaj zog thiab ua lub luag haujlwm sib txawv hauv ntau qhov chaw sib txawv. Tshwj xeeb, hauv kev kho dej, PolyDADMAC siv ua cationic flocculant thiab coagulant. Los ntawm kev nqus thiab txuas, nws tuaj yeem tshem tawm cov khoom seem thiab cov khoom tsis huv hauv dej thiab txhim kho dej zoo. Hauv kev lag luam textile, PolyDADMAC, ua tus neeg sawv cev kho xim tsis muaj formaldehyde, tuaj yeem txhim kho cov xim kho ntawm cov xim thiab ua rau cov ntaub ci ntsa iab thiab tiv taus kev ploj. Hauv cov txheej txheem ua ntawv, PolyDADMAC siv ua tus neeg sawv cev ntes khib nyiab anionic thiab AKD kho accelerator, pab txhim kho cov ntawv zoo thiab txo cov nqi tsim khoom. Tsis tas li ntawd, hauv kev lag luam roj av, PolyDADMAC siv ua av nplaum stabilizer rau kev khawb thiab acid fracturing cationic modifier hauv kev txhaj dej los txhim kho kev rov qab roj av.
Txawm li cas los xij, PolyDADMAC tsis yog ib qho khoom siv zoo. Txawm hais tias nws muaj ntau yam khoom zoo heev thiab thaj chaw siv, koj tseem yuav tsum tau them sai sai rau cov teeb meem kev nyab xeeb thaum siv nws. Piv txwv li, yuav tsum tsis txhob kov ncaj qha rau daim tawv nqaij thiab qhov muag thaum siv kom tiv thaiv kev khaus. Ntxiv rau qhov ntawd, nws yuav tsum tau kaw thiab khaws cia tom qab siv kom tsis txhob kov cov tshuaj oxidants muaj zog thiab khaws cia rau hauv qhov chaw txias thiab qhuav. Txawm hais tias PolyDADMAC tsis muaj tshuaj lom, koj tseem yuav tsum ua haujlwm nrog kev ceev faj thiab ua raws li cov cai kev nyab xeeb thiab cov txheej txheem ua haujlwm.
Hauv kev xaus lus, PolyDADMAC, ua ib yam tshuaj polymer, siv dav hauv ntau qhov chaw. Nws cov khoom siv tshuaj tshwj xeeb thiab kev ua tau zoo heev ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev kho dej, textiles, ntawv, thiab cov roj av. Txawm li cas los xij, koj tseem yuav tsum tau them sai sai rau cov teeb meem kev nyab xeeb thaum siv thiab ua raws li cov cai thiab cov txheej txheem ua haujlwm. Tsuas yog los ntawm kev ua kom muaj kev nyab xeeb thiab tsim nyog ntawm PolyDADMAC peb thiaj li paub txog nws lub peev xwm thiab coj kev yooj yim dua thiab cov txiaj ntsig rau peb lub neej thiab kev ua haujlwm.
