Polyacrylamide (PAM) yog linear polymer nrog flocculation, adhesion, luag txo, thiab lwm yam khoom. Raws li ib tugPolymer Organic Flocculant, nws yog dav siv hauv kev kho dej. Thaum siv PAM, cov txheej txheem ua haujlwm raug yuav tsum tau ua raws li kom tsis txhob muaj tshuaj lom neeg.
PAM Ntxiv txheej txheem
RauKhoom PAM, nws yuav tsum tau muab ntxiv rau hauv dej tom qab yaj. Rau cov dej sib txawv, ntau hom PAM yuav tsum tau xaiv, thiab cov kev daws teeb meem sib faib ua ntau qhov sib txawv. Thaum ntxiv polyacrylamide, kev saib xyuas yuav tsum tau them rau cov ntsiab lus hauv qab no:
Kev Xeem Jar:Txiav txim siab qhov zoo tshaj plaws specifications thiab ntau npaum li cas los ntawm kev xeem lub thawv. Hauv kev sim lub thawv, maj mam nce cov koob tshuaj ntawm polyacrylamide, saib xyuas cov nyhuv flocculation, thiab txiav txim siab qhov pom zoo npaum li cas.
Npaj PAM Aqueous Solution:Txij li thaum anionic PAM (APAM) thiab nonionic PAM (NPAM) muaj qhov hnyav dua molecular thiab lub zog muaj zog, anionic polyacrylamide feem ntau yog tsim los rau hauv cov kua dej nrog cov ntsiab lus ntawm 0.1% (xa mus rau cov ntsiab lus khoom) thiab tsis muaj ntsev, tsis muaj dej huv. Xaiv cov enameled, galvanized aluminium, lossis cov thoob yas es tsis txhob ntim cov hlau li hlau ions catalyze cov tshuaj degradation ntawm tag nrho cov PAM. Thaum lub sij hawm npaj, polyacrylamide yuav tsum tau muab sib npaug zos rau hauv cov dej nplawm thiab rhuab kom tsim nyog (<60 ° C) kom nrawm nrawm. Thaum dissolving, yuav tsum tau them nyiaj mloog mus ntxiv cov khoom sib npaug thiab maj mam mus rau hauv lub dissolver nrog stirring thiab cua kub ntsuas kom tsis txhob solidification. Cov tshuaj yuav tsum tau npaj nyob rau hauv ib tug haum kub, thiab lub sij hawm ntev thiab hnyav mechanical shearing yuav tsum raug zam. Nws raug pom zoo tias lub tshuab tov tig ntawm 60-200 rpm; txwv tsis pub, nws yuav ua rau polymer degradation thiab cuam tshuam rau kev siv. Nco ntsoov tias cov tshuaj PAM aqueous yuav tsum tau npaj tam sim ua ntej siv. Kev khaws cia ntev ntev yuav ua rau kev ua haujlwm qis dua. Tom qab ntxiv cov tshuaj flocculant aqueous rau kev ncua, kev sib zog ua kom ntev ntev yuav ua rau cov flocs uas tau tsim.
Dosing Requirements:Siv lub koob tshuaj los ntxiv PAM. Nyob rau theem pib ntawm cov tshuaj tiv thaiv ntawm kev ntxiv PAM, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj kev sib cuag ntawm cov tshuaj thiab cov dej kom tau txais kev kho ntau li ntau tau, nce stirring, los yog nce tus nqi ntws.
Tej yam uas yuav tsum nco ntsoov thaum ntxiv PAM
Lub Sijhawm Dissolution:Ntau hom PAM muaj lub sijhawm sib txawv. Cationic PAM muaj lub sijhawm luv luv luv, thaum anionic thiab nonionic PAM muaj lub sijhawm tawg ntev dua. Xaiv lub sij hawm sib cais tsim nyog tuaj yeem pab txhim kho cov nyhuv flocculation.
Dosage thiab Concentration:Kev noj tshuaj kom tsim nyog yog tus yuam sij kom ua tiav qhov zoo tshaj plaws flocculation nyhuv. Kev noj ntau dhau tuaj yeem ua rau cov coagulation ntau dhau ntawm colloids thiab tshem tawm cov khoom, tsim cov sediments loj es tsis txhob flocs, yog li cuam tshuam rau qhov zoo ntawm cov effluent.
Kev sib xyaw ua ke:Txhawm rau kom muaj kev sib xyaw ua ke ntawm PAM thiab cov dej khib nyiab, cov khoom siv sib xyaw tsim nyog yuav tsum tau xaiv. Kev sib xyaw tsis sib xws tuaj yeem ua rau tsis tiav ntawm PAM, yog li cuam tshuam rau nws cov nyhuv flocculation.
Dej Environmental Conditions:Ib puag ncig yam xws li pH tus nqi, kub, siab, thiab lwm yam, kuj tseem yuav cuam tshuam rau cov nyhuv flocculation ntawm PAM. Nyob ntawm cov dej khib nyiab zoo, cov kev ntsuas no yuav xav tau kev hloov kho kom pom cov txiaj ntsig zoo.
Dosing Sequence:Nyob rau hauv ib tug multi-agent dosing system, nws yog ib qho tseem ceeb kom nkag siab txog cov koob tshuaj ntawm ntau tus neeg sawv cev. Kev noj tshuaj tsis raug cai yuav cuam tshuam rau kev sib cuam tshuam ntawm PAM thiab colloids thiab cov khoom raug tshem tawm, yog li cuam tshuam rau cov nyhuv flocculation.
Polyacrylamide(PAM) yog ntau yam polymer nrog ntau yam kev siv, tshwj xeeb hauv kev kho dej. Txhawm rau ua kom nws cov txiaj ntsig zoo tshaj plaws thiab zam kev siv nyiaj, nws yog qhov tseem ceeb uas yuav tsum ua raws li cov txheej txheem ua haujlwm kom raug. Los ntawm kev ua tib zoo xav txog yam xws li lub sij hawm sib cais, ntau npaum li cas, kev sib xyaw ua ke, dej ib puag ncig, thiab kev sib xyaw ua ke, koj tuaj yeem siv PAM kom ua tau raws li qhov xav tau ntawm flocculation thiab txhim kho dej zoo.
