Yuav ua li cas ntxiv PAM

Polyacrylamide (PAM) yog ib qho polymer linear nrog flocculation, adhesion, drag reduction, thiab lwm yam khoom. Raws li ib tugCov khoom siv polymer organic flocculant, nws yog siv dav hauv kev kho dej. Thaum siv PAM, yuav tsum ua raws li cov txheej txheem ua haujlwm kom raug kom tsis txhob muaj kev nkim tshuaj.

Cov Txheej Txheem Ntxiv PAM

RauPAM khov kho, nws yuav tsum tau ntxiv rau hauv dej tom qab yaj. Rau cov dej zoo sib txawv, ntau hom PAM yuav tsum tau xaiv, thiab cov tshuaj sib piv rau hauv cov concentration sib txawv. Thaum ntxiv polyacrylamide, yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:

Kev Ntsuas Lub Raj Mis:Txheeb xyuas cov lus qhia zoo tshaj plaws thiab cov koob tshuaj los ntawm kev sim lub thawv. Hauv kev sim lub thawv, maj mam nce cov koob tshuaj ntawm polyacrylamide, saib cov nyhuv ntawm flocculation, thiab txiav txim siab qhov koob tshuaj zoo tshaj plaws.

Kev Npaj Cov Tshuaj PAM Aqueous:Vim tias anionic PAM (APAM) thiab nonionic PAM (NPAM) muaj qhov hnyav molecular siab dua thiab muaj zog dua, anionic polyacrylamide feem ntau yog tsim rau hauv cov kua dej nrog qhov concentration ntawm 0.1% (hais txog cov ntsiab lus khov) thiab tsis muaj ntsev, dej huv nruab nrab. Xaiv cov thoob enameled, galvanized txhuas, lossis cov thoob yas es tsis txhob siv cov thawv hlau vim tias cov hlau ions catalyze cov tshuaj degradation ntawm tag nrho PAM. Thaum lub sijhawm npaj, polyacrylamide yuav tsum tau muab sib npaug rau hauv dej do thiab cua sov kom raug (<60°C) kom nrawm dissolve. Thaum dissolving, yuav tsum tau them sai sai rau kev ntxiv cov khoom sib npaug thiab qeeb rau hauv dissolver nrog kev do thiab cua sov ntsuas kom tsis txhob khov. Cov tshuaj yuav tsum tau npaj ntawm qhov kub thiab txias, thiab yuav tsum tsis txhob siv tshuab ntev thiab hnyav. Nws raug pom zoo tias lub mixer tig ntawm 60-200 rpm; txwv tsis pub, nws yuav ua rau polymer degradation thiab cuam tshuam rau kev siv. Nco ntsoov tias PAM aqueous kua yuav tsum tau npaj tam sim ntawd ua ntej siv. Kev khaws cia ntev yuav ua rau maj mam txo qis hauv kev ua tau zoo. Tom qab ntxiv cov kua dej flocculant rau hauv cov tshuaj, kev sib tov ua kom nrawm ntev yuav ua rau cov flocs uas tau tsim puas tsuaj.

Cov Kev Cai Rau Kev Noj Tshuaj:Siv lub cuab yeej ntsuas kom ntxiv PAM. Thaum pib ntawm kev ntxiv PAM, nws yog ib qho tsim nyog los ua kom muaj kev sib cuag ntawm cov tshuaj thiab cov dej uas yuav tsum tau kho ntau li ntau tau, ua kom sib xyaw ntau dua, lossis ua kom nrawm dua.

Tej yam yuav tsum nco ntsoov thaum ntxiv PAM

Lub Sijhawm Yaj:Cov PAM sib txawv muaj lub sijhawm yaj sib txawv. Cationic PAM muaj lub sijhawm yaj luv luv, thaum anionic thiab nonionic PAM muaj lub sijhawm yaj ntev dua. Kev xaiv lub sijhawm yaj kom haum tuaj yeem pab txhim kho cov nyhuv flocculation.

Kev Siv Tshuaj thiab Kev Ntsuas:Kev siv tshuaj kom raug yog qhov tseem ceeb rau kev ua kom cov dej ntws zoo tshaj plaws. Kev siv tshuaj ntau dhau yuav ua rau cov colloids thiab cov khoom me me uas raug tshem tawm sib xyaw ua ke ntau dhau, ua rau cov av loj loj es tsis yog cov flocs, yog li ntawd cuam tshuam rau qhov zoo ntawm cov dej ntws.

Cov xwm txheej sib xyaw:Yuav kom ntseeg tau tias muaj kev sib xyaw PAM thiab cov dej khib nyiab txaus, yuav tsum xaiv cov khoom siv thiab cov txheej txheem sib xyaw kom haum. Kev sib xyaw tsis sib xws yuav ua rau PAM yaj tsis tiav, yog li ntawd cuam tshuam rau nws cov nyhuv flocculation.

Cov xwm txheej ib puag ncig ntawm dej:Tej yam ib puag ncig xws li tus nqi pH, kub, siab, thiab lwm yam, kuj yuav cuam tshuam rau qhov cuam tshuam ntawm PAM flocculation. Nyob ntawm cov xwm txheej zoo ntawm cov dej khib nyiab, cov kev ntsuas no yuav tsum tau hloov kho kom tau txiaj ntsig zoo tshaj plaws.

Kev Siv Tshuaj:Hauv ib lub tshuab siv ntau yam tshuaj, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem ntawm ntau yam tshuaj. Cov txheej txheem ntawm kev siv tshuaj tsis raug yuav cuam tshuam rau kev sib cuam tshuam ntawm PAM thiab cov colloids thiab cov khoom me me uas raug tshem tawm, yog li ntawd cuam tshuam rau cov nyhuv ntawm flocculation.

Polyacrylamide(PAM) yog ib qho polymer uas siv tau ntau yam, tshwj xeeb tshaj yog hauv kev kho dej. Yuav kom ua tau zoo tshaj plaws thiab tsis txhob muaj kev pov tseg, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem ua haujlwm kom raug. Los ntawm kev xav txog cov yam ntxwv xws li lub sijhawm yaj, qhov ntau npaum li cas, cov xwm txheej sib tov, cov xwm txheej ib puag ncig dej, thiab cov txheej txheem ntawm kev noj, koj tuaj yeem siv PAM kom zoo kom ua tiav cov txiaj ntsig flocculation xav tau thiab txhim kho cov dej zoo.
