Polyacrylamide Molecular Water Treatment Chemicals
Polyacrylamide (PAM) yog ib lub ntsiab lus dav dav rau acrylamide homopolymer lossis copolymerized nrog lwm cov monomers, thiab yog ib qho ntawm ntau hom kev siv dej-soluble polymers.Vim hais tias cov txheej txheem ntawm polyacrylamide muaj cov pab pawg amide, nws yog ib qho yooj yim los tsim hydrogen bonds, uas ua rau nws muaj dej solubility zoo thiab muaj tshuaj lom neeg ua hauj lwm, thiab nws yog ib qho yooj yim kom tau txais ntau yam kev hloov kho ntawm ceg saw los yog network qauv los ntawm grafting los yog crosslinking., Nws yog dav siv hauv kev tshawb nrhiav roj av, kev kho dej, textile, papermaking, mineral processing, tshuaj, kev ua liaj ua teb thiab lwm yam lag luam, thiab yog lub npe hu ua "auxiliaries for all industries".Daim ntawv thov tseem ceeb hauv teb chaws txawv teb chaws yog kev kho dej, papermaking, mining, metallurgy, thiab lwm yam.;nyob rau hauv Suav teb, qhov loj tshaj plaws yog tam sim no siv nyob rau hauv lub tshav pob ntawm cov roj extraction, thiab cov loj hlob sai tshaj plaws nyob rau hauv lub teb ntawm kev kho dej thiab papermaking.
Kev kho dej:
Kev kho dej muaj xws li kev kho dej nyoos, kev kho dej phwj thiab kev kho dej hauv kev lag luam.Siv ua ke nrog cov pa roj carbon activated hauv kev kho cov dej nyoos, nws tuaj yeem siv rau coagulation thiab qhia meej ntawm cov khoom tshem tawm hauv cov dej hauv tsev.Kev siv cov organic flocculant acrylamide es tsis txhob inorganic flocculant tuaj yeem ua rau kom cov dej huv huv tuaj yeem ua rau ntau dua 20% txawm tias tsis hloov kho lub tank;hauv kev kho cov dej phwj tuaj, kev siv cov polyacrylamide tuaj yeem ua rau kev siv cov dej rov ua dua tshiab thiab tuaj yeem siv los ua Sludge dewatering;siv los ua tus neeg sawv cev tseem ceeb hauv kev kho dej hauv dej.Qhov loj tshaj plaws ntawm daim ntawv thov ntawm polyacrylamide txawv teb chaws yog kev kho dej, thiab daim ntawv thov nyob rau hauv daim teb no nyob rau hauv Tuam Tshoj yog nce.Lub luag haujlwm tseem ceeb ntawm polyacrylamide hauv kev kho dej: [2]
(1) Txo tus nqi ntawm flocculant.Raws li qhov ua tiav ntawm kev ua tiav cov dej zoo tib yam, polyacrylamide yog siv los ua coagulant pab ua ke nrog lwm cov flocculants, uas tuaj yeem txo cov nqi ntawm flocculant siv;(2) Txhim kho dej zoo.Hauv kev kho dej haus thiab kev kho dej khib nyiab, kev siv polyacrylamide ua ke nrog inorganic flocculants tuaj yeem txhim kho dej zoo;(3) Ua kom muaj zog floc thiab sedimentation tshaj tawm.Cov flocs tsim los ntawm polyacrylamide muaj lub zog siab thiab kev ua haujlwm zoo sedimentation, yog li ua kom cov khoom sib cais ceev ceev thiab ua kom yooj yim sludge lub cev qhuav dej;(4) Anti-corrosion thiab anti-scaling ntawm lub circulating txias system.Kev siv cov polyacrylamide tuaj yeem txo qis ntawm cov inorganic flocculants zoo heev, yog li zam kom tsis txhob muaj cov khoom siv tsis zoo nyob rau saum npoo ntawm cov khoom siv thiab ua kom qeeb ntawm corrosion thiab scaling ntawm cov cuab yeej.
Polyacrylamide yog dav siv los ua kev pab tuav pov hwm, lim pab, qib tus neeg sawv cev, thiab lwm yam hauv daim ntawv ua haujlwm los txhim kho cov ntawv zoo, slurry dehydration kev ua tau zoo, tuav tus nqi ntawm cov fibers zoo thiab muab tub lim, txo cov khoom siv raw thiab ib puag ncig muaj kuab paug, siv los ua cov khoom tawg. txhim kho cov ntawv uniformity.Polyacrylamide feem ntau yog siv rau hauv ob yam hauv kev lag luam ntawv.Ib qho yog txhawm rau nce tus nqi khaws cia ntawm cov fillers thiab pigments kom txo tau cov khoom siv raw thiab ib puag ncig muaj kuab paug;lwm qhov yog kom muaj zog ntawm daim ntawv.Ntxiv polyacrylamide rau cov ntaub ntawv tuaj yeem ua rau kom tus nqi khaws cia ntawm cov fibers zoo thiab muab tub lim rau hauv lub vas thiab ua kom lub cev qhuav dej ntawm cov ntaub ntawv.Lub mechanism ntawm kev txiav txim ntawm polyacrylamide yog hais tias cov hais nyob rau hauv lub slurry yog flocculated thiab khaws cia nyob rau hauv lub lim ntaub los ntawm neutralization los yog bridging.Kev tsim cov flocs tuaj yeem ua rau cov dej hauv cov slurry yooj yim lim tawm, txo qhov poob ntawm fibers hauv dej dawb, txo cov pa phem ib puag ncig, thiab pab txhim kho kev ua haujlwm ntawm kev pom thiab cov khoom siv sedimentation.
