Yuav ua li cas xaiv polyacrylamide nyob ntawm qhov concentration ntawm colloids thiab tshem tawm cov khib nyiab hauv dej. Yog li yuav ua li cas xaiv PAM haum?
1. Nkag siab qhov chaw ntawm cov dej phwj tuaj Ua ntej, peb yuav tsum nkag siab txog qhov chaw, xwm txheej, muaj pes tsawg leeg, cov ntsiab lus ntawm cov sludge. Feem ntau hais lus, cationic polyacrylamide yog siv los kho cov organic sludge, thiab anionic polyacrylamide yog siv los kho inorganic sludge. Thaum pH siab, cationic polyacrylamide yuav tsum tsis txhob siv, thiab thaum twg, anionic polyacrylamide yuav tsum tsis txhob siv. Muaj zog acidity ua rau nws tsis tsim nyog siv anionic polyacrylamide. Thaum cov ntsiab lus ntawm cov sludge siab, cov khoom siv ntawm polyacrylamide yog loj.
2. Kev xaiv ntawm ionicity Rau sludge uas yuav tsum tau dehydrated hauv cov dej phwj tuaj kho, koj tuaj yeem xaiv flocculants nrog ionicity sib txawv los ntawm kev sim me me los xaiv cov polyacrylamide uas tsim nyog tshaj plaws, uas tuaj yeem ua tiav qhov zoo tshaj plaws flocculation nyhuv thiab txo qhov ntau npaum, txuag nqi.
3. Kev xaiv ntawm qhov hnyav molecular Feem ntau hais lus, qhov siab dua qhov hnyav ntawm cov khoom siv polyacrylamide, qhov viscosity ntau dua, tab sis hauv kev siv, qhov hnyav molecular ntawm cov khoom, qhov kev siv tau zoo dua. Hauv kev siv tshwj xeeb, qhov hnyav molecular ntawm polyacrylamide yuav tsum tau txiav txim siab raws li qhov tseeb daim ntawv thov kev lag luam, dej zoo thiab cov khoom siv kho mob.
Thaum koj yuav thiab siv PAM thawj zaug, nws raug nquahu kom muab cov xwm txheej tshwj xeeb ntawm cov dej phwj tuaj rau cov chaw tsim khoom flocculant, thiab peb yuav pom zoo rau hom khoom tsim nyog rau koj. Thiab xa cov qauv rau kev kuaj. Yog tias koj muaj kev paub ntau hauv koj qhov kev kho dej phwj tuaj, koj tuaj yeem qhia peb koj cov kev xav tau tshwj xeeb, daim ntawv thov, thiab cov txheej txheem, lossis ncaj qha muab peb cov qauv PAM uas koj tab tom siv tam sim no, thiab peb yuav phim koj nrog txoj cai polyacrylamide.
