Muaj ntau cov ntsiab lus uas cuam tshuam rau cov nyhuv ntawm polyacrylamide (PAM), uas tuaj yeem faib ua cov dej ua haujlwm zoo, cov khoom ntawm Pam nws tus kheej, thiab cov xwm txheej sab nraud, thiab cov xwm txheej sab nraud. Ntawm no yog cov ncauj lus kom ntxaws ntxaws ntawm cov xwm txheej no:
1. Dej Ua Kom Zoo
- PH: Cov nyhuv ntawm PAM sib txawv nrog tus nqi PH. Ntau hom PAM (piv txwv li, anionic, cationic) ua haujlwm sib txawv ntawm cov pH qhov tseem ceeb. Feem ntau, anionic pam ua haujlwm zoo dua nyob rau hauv nruab nrab ntawm cov xwm txheej, thaum Cationic Pam ua haujlwm zoo dua hauv nruab nrab rau cov acidic tej yam kev mob.
- Salinity: dej nrog Salinculation Floinculation ntawm Pam vim tias ntsev ions sib tw nrog anionic lossis cov khoom sib xyaw ua ke.
- Turbidity: Qhov kev ua kom nruj me me hauv dej, qhov zoo dua cov flocculation ntawm cov pa vim tias muaj cov neeg raug tshem tawm uas tuaj yeem raug tshem tawm los ntawm PAM.
- Cov ntsiab lus organic: Cov kab ke hauv dej tuaj yeem cuam tshuam rau cov dej flocculation ntawm Pam, thiab cov ntsiab lus organic tej zaum yuav cuam tshuam cov kev khi ntawm Pam rau kev teeb meem.
- Lub Hardness: calcium thiab magnesium kuj tseem tuaj yeem cuam tshuam qhov ua tau zoo, vim tias lawv tuaj yeem khi rau cov pps, txo nws lub peev xwm flocculation.
2. Kev khiav hauj lwm
- Qhov ntsuas: Qhov ntau npaum ntawm Pam yuav tsum tsim nyog, ntau dhau lossis tsawg dua yuav cuam tshuam rau Flocculation. Ntau dhau yuav ua rau cov floc yuav tsum xoob dhau, thiab tsawg dhau yuav tsis muaj peev xwm ua tau cov floc zoo. Ib qho ntxiv, txoj kev txhaj tshuaj yuav cuam tshuam rau kev siv cov nyhuv ntawm Pam, thiab kev siv tshuaj pleev yuav tswj tau cov txiaj ntsig zoo dua thiab txhim kho kev ua tiav.
- Stirring ceev: Lub nrawm yuav cuam tshuam rau kev sib cais thiab dispersion nyhuv ntawm Pam. Kev ua txhaum ntau dhau yuav ua rau cov kev so ntawm cov molecular chart ntawm Pam, cuam tshuam nws cov flocculation kev ua tau zoo. Qhov kev ntxhov siab tsis txaus yuav ua rau muaj kev faib tawm phaus dav dav ntawm cov polymer, uas tseem yuav cuam tshuam nws cov txiaj ntsig flocculation.
- Lub sijhawm ua tiav: PAM xav tau sijhawm txaus kom yaj, txwv tsis pub nws yuav tsis tau txais nws cov nyhuv flocculating. Ntau hom PAMS siv sijhawm sib txawv los yaj, thiab feem ntau, tsis muaj ntev dua ntev ntev kom yaj.
- Qhov kub: Qhov kub thiab txias: Qhov cuam tshuam nrog kev sib cais thiab flocculation cuam tshuam ntawm PAM. Kev nce qib kub tuaj yeem ua kom nrawm dua cov kev sib cais ntawm cov pam, tab sis ntau dhau ntawm qhov kub yuav ua rau nws ua tsis tau.
- Nws lub sijhawm sib xyaw: lub sijhawm sib xyaw tsis txaus yuav ua rau cov neeg muaj kev sib chwv nrog cov khoom siv hauv dej, uas yuav cuam tshuam rau cov txiaj ntsig flocculation.
3. Qhov xwm ntawm Pam nws tus kheej
- Hom: Ntau hom PAMS (piv txwv li, anionic, cationic, tsis yog-ionic) haum rau cov khoom sib txawv. Xaiv hom yog yog qhov premise kom ntseeg tau tias cov nyhuv.
- Molecular qhov hnyav: qhov loj me ntawm cov molecular nyhav txiav txim siab flocculation muaj peev xwm ntawm cov tib si. Siab molecular hnyav Pam muaj lub zog flocculation cuam tshuam, tab sis nws nyuaj rau yaj.
- Monomer Nub tuaj: Tus nqi ntawm monomer nyob hauv Pam kuj tseem yuav cuam tshuam nws cov hauj lwm zoo, thiab siab dhau ntawm cov chaw nyob yuav txo tau nws cov flocculation kev ua tau zoo.
- Purity: High-purity PAM tuaj yeem hloov tau nws cov txiaj ntsig focculation.
4. Sab nraud ib puag ncig
- Illumination: kev kis lub teeb pom kev yuav ua rau muaj kev cuam tshuam ntawm Pam molecular chains, cuam tshuam rau lawv cov txiaj ntsig flocculation.
- Kev Cia Yuav Tsum Tau Muab Cia Rau Hauv Ib puag ncig qhuav, tsaus, Txwv tsis pub nws yuav ua rau nws ua tau zoo rau kev ua tsis taus.
- Cov kev thauj mus los: kev co loj thiab kub yuav tsum tau zam thaum thauj mus los tiv thaiv Pam los ntawm agglomerating lossis degrading.
Tsis tas li ntawd, txawm hais tias qhov loj me me tsis cuam tshuam rau kev ua tau zoo ntawm Pam, nws cuam tshuam rau nws lub sijhawm sib cais. Cov degree ntawm kev sib cais yog tseem muaj feem xyuam rau cov neeg ua haujlwm ntawm cov neeg, yog tias tib neeg ua yuam kev ntawm tus neeg sawv cev ntawm tus neeg sawv cev, thiab tsim cov nyhuv ntawm cov khib nyiab, thiab tsim cov nyhuv ntawm tus neeg pov tseg.
