Kev nkag siab tsis zoo thaum xaiv PAM

Polyacrylamide(PAM), raws li cov khoom siv polymer flocculant, yog dav siv nyob rau hauv ntau yam dej phwj kho mob scenarios. Txawm li cas los xij, ntau tus neeg siv tau poob rau hauv qee qhov kev nkag siab yuam kev thaum xaiv thiab siv cov txheej txheem. Kab lus no yog tsim los nthuav tawm cov kev nkag siab tsis zoo no thiab muab kev nkag siab thiab cov lus qhia kom raug.

Kev nkag siab yuam kev 1: Qhov loj dua qhov hnyav molecular, qhov ua tau zoo ntawm flocculation ntau dua.

Thaum xaiv polyacrylamide, ntau tus neeg xav tias tus qauv nrog qhov hnyav dua molecular yuav tsum muaj ntau dua flocculation efficiency. Tab sis qhov tseeb, muaj ntau pua tus qauv ntawm polyacrylamide, uas tsim nyog rau cov dej sib txawv. Qhov xwm ntawm cov dej khib nyiab tsim los ntawm cov chaw tsim khoom hauv kev lag luam sib txawv yog txawv. Tus nqi pH thiab cov impurities tshwj xeeb ntawm cov dej sib txawv yog qhov sib txawv. Tej zaum lawv yuav yog acidic, alkaline, nruab nrab, los yog muaj roj, organic teeb meem, xim, sediment, thiab lwm yam. Yog li ntawd, nws yog ib qho nyuaj rau ib hom polyacrylamide kom tau raws li tag nrho cov kev xav tau kev kho dej khib nyiab. Txoj hauv kev kom raug yog thawj zaug xaiv tus qauv los ntawm kev sim, thiab tom qab ntawd ua cov kev sim tshuab los txiav txim siab qhov kev pom zoo kom ua tiav cov txiaj ntsig zoo tshaj plaws.

Kev tsis nkag siab 2: Qhov siab dua qhov kev teeb tsa kev teeb tsa, qhov zoo dua

Thaum npaj cov tshuaj polyacrylamide, ntau tus neeg siv ntseeg tias qhov siab dua qhov concentration, qhov zoo dua ntawm cov khoom flocculation. Txawm li cas los xij, qhov kev xav no tsis raug. Qhov tseeb, qhov concentration ntawm PAM configuration yuav tsum tau txiav txim raws li cov dej phwj tshwj xeeb thiab sludge tej yam kev mob. Feem ntau hais lus, PAM cov kev daws teeb meem nrog qhov concentration ntawm 0.1% -0.3% yog haum rau flocculation thiab sedimentation, thaum lub concentration rau hauv nroog thiab industrial sludge dewatering yog 0.2% -0.5%. Thaum muaj ntau cov impurities hauv cov dej phwj tuaj, qhov concentration ntawm PAM yuav tsum tau nce kom tsim nyog. Yog li ntawd, qhov tsim nyog configuration concentration yuav tsum tau txiav txim siab los ntawm kev sim ua ntej siv los xyuas kom meej qhov kev siv zoo tshaj plaws.

Kev nkag siab yuam kev 3: Lub sij hawm ua kom yaj thiab nplawm ntev dua, qhov zoo dua

Polyacrylamide yog ib qho dawb crystalline particle uas yuav tsum tau yaj tag nrho kom ua tiav cov txiaj ntsig zoo tshaj plaws. Ntau tus neeg siv xav tias qhov ntev ntawm kev sib cais thiab nplawm lub sijhawm, qhov zoo dua, tab sis qhov tseeb qhov no tsis yog qhov teeb meem. Yog hais tias lub sij hawm stirring ntev dhau lawm, nws yuav ua rau ib feem ntawm PAM molecular saw thiab cuam tshuam rau flocculation kev ua tau zoo. Feem ntau hais lus, lub sijhawm yaj thiab nplawm yuav tsum tsis pub tsawg dua 30 feeb thiab yuav tsum tau txuas ntxiv kom tsim nyog thaum lub caij ntuj no kub tsawg. Yog hais tias lub sij hawm dissolution thiab stirring yog luv luv, PAM yuav tsis tau tag nrho yaj, uas yuav ua rau tsis muaj peev xwm ua tau sai flocculation nyob rau hauv dej phwj tuaj. Yog li ntawd, cov neeg siv yuav tsum xyuas kom meej txaus dissolution thiab stirring lub sij hawm thaum siv nws los xyuas kom meej lub flocculation nyhuv ntawm PAM.

Kev nkag siab yuam kev 4: Ionicity / Ionic degree yog tib lub hauv paus rau kev xaiv

Raws li ib qho ntawm cov cim tseem ceeb ntawm polyacrylamide, ionicity yog hais txog qhov tsis zoo thiab zoo ionic nqi thiab nws cov nqi ceev. Ntau tus neeg them nyiaj ntau dhau rau qhov ionicity thaum yuav khoom, xav tias qhov siab dua qhov zoo dua. Tab sis qhov tseeb, qib ntawm ionicity muaj feem xyuam nrog qhov loj ntawm qhov hnyav molecular. Qhov siab dua qhov ionicity, qhov me me ntawm qhov hnyav molecular, thiab tus nqi siab dua. Nyob rau hauv cov txheej txheem xaiv, ntxiv rau ionicity, lwm yam yuav tsum tau xav txog, xws li cov dej tsis zoo, cov kev xav tau rau cov nyhuv flocculation, thiab lwm yam. Yog li ntawd, tus qauv tsis tuaj yeem xaiv raws li qib ntawm ionization. Kev sim ntxiv yog yuav tsum tau txiav txim siab tus qauv xav tau.

Raws li ib tugflocculant, polyacrylamide plays lub luag haujlwm tseem ceeb hauv kev lag luam kho dej. Thaum koj xav tau xaiv cov specifications uas haum koj, thov hu rau kuv.
