Positively Charged Polyacrylamide (PAM) Polymer rau Kev Kho Dej
Polyacrylamide (PAM) yog cov khoom siv hluavtaws uas siv dav hauv kev kho dej. Thaum PAM raug them zoo, nws yog hu ua cationic polyacrylamide (CPAM). CPAM muaj txiaj ntsig tshwj xeeb hauv kev siv dej kho mob vim tias nws muaj peev xwm tshem tawm cov khib nyiab, turbidity, thiab lwm yam impurities los ntawm dej.
CPAM ua haujlwm los ntawm kev nyiam cov khoom tsis zoo hauv dej, xws li cov teeb meem organic, kab mob, thiab cov algae, thiab tsim cov pawg loj uas tuaj yeem tshem tau yooj yim los ntawm cov txheej txheem ntawm lub cev xws li sedimentation lossis pom. CPAM kuj tseem siv tau los txo cov kuab paug hauv dej, xws li cov hlau hnyav thiab phosphates, los ntawm cov txheej txheem hu ua coagulation thiab flocculation.
Positively Charged Polyacrylamide (PAM) Polymer rau Daim Ntawv Thov Kev Kho Dej
Polyacrylamide (PAM) yog cov khoom siv hluavtaws uas tuaj yeem raug nqi zoo lossis tsis zoo nyob ntawm cov txheej txheem tsim khoom. Daim ntawv them nyiaj zoo ntawm PAM feem ntau hu ua cationic polyacrylamide.
Hauv kev kho dej, cationic polyacrylamide feem ntau yog siv los ua coagulant pab txhawm rau txhim kho kev ua haujlwm ntawm cov txheej txheem coagulation. Coagulation yog ib kauj ruam tseem ceeb hauv kev kho dej uas suav nrog kev sib ntxiv ntawm cov tshuaj kom tsis txhob muaj cov kab mob thiab tsim cov aggregates loj, uas tuaj yeem raug tshem tawm los ntawm sedimentation lossis pom.
Cationic polyacrylamide tuaj yeem txhim kho coagulation los ntawm kev ua kom qhov loj me thiab qhov ntom ntawm cov flocs tsim thaum lub sijhawm ua haujlwm, ua rau kev daws teeb meem zoo dua thiab txhim kho kev tshem tawm ntawm impurities. Nws tseem tuaj yeem txo cov coagulant ntau npaum li cas thiab txo tus nqi tag nrho ntawm kev kho dej.
Ntxiv nrog rau nws siv hauv kev kho dej, cationic polyacrylamide muaj cov ntawv thov hauv lwm qhov chaw xws li kev kho dej khib nyiab, ntawv ua, thiab roj thiab roj ntau lawm. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov, txawm li cas los xij, kev siv polyacrylamide, tshwj xeeb tshaj yog daim ntawv cationic, tuaj yeem muaj kev cuam tshuam ib puag ncig yog tias tsis tswj xyuas kom zoo. Yog li ntawd, nws yog ib qho tseem ceeb kom ua raws li cov kev coj ua zoo tshaj plaws thiab cov kev cai thaum siv cov polymer no.
