Raws li peb txhua tus paub, ntau hom polyacrylamide muaj ntau hom kev kho dej phwj tuaj thiab cov teebmeem sib txawv. Yog li polyacrylamide yog txhua yam dawb, yuav ua li cas kom paub qhov txawv ntawm nws cov qauv?
Muaj 4 txoj hauv kev yooj yim los paub qhov txawv ntawm cov qauv ntawm polyacrylamide:
1. Peb txhua tus paub tias cov cationic polyacrylamide kim tshaj plaws hauv kev ua lag luam, ua raws li cov non-ionic polyacrylamide, thiab thaum kawg anionic polyacrylamide. Los ntawm tus nqi, peb tuaj yeem txiav txim siab ua ntej txog hom ion.
2. Yaj cov polyacrylamide los ntsuas tus nqi pH ntawm cov tshuaj. Cov nqi pH sib xws ntawm ntau yam qauv sib txawv.
3. Ua ntej, xaiv cov khoom anionic polyacrylamide thiab cationic polyacrylamide, thiab yaj lawv sib cais. Sib tov cov khoom polyacrylamide uas yuav tsum tau sim nrog ob qho kev daws teeb meem PAM. Yog tias nws cuam tshuam nrog cov khoom anionic polyacrylamide, nws txhais tau tias Polyacrylamide yog cationic. Yog tias nws cuam tshuam nrog cations, nws ua pov thawj tias cov khoom PAM yog anionic lossis non-ionic. Qhov tsis zoo ntawm txoj kev no yog tias nws tsis tuaj yeem txheeb xyuas qhov tseeb seb cov khoom yog anionic lossis non-ionic polyacrylamide. Tab sis peb tuaj yeem txiav txim siab los ntawm lawv lub sijhawm yaj, anions yaj sai dua li cov non-ions. Feem ntau, anion yaj tag nrho hauv ib teev, thaum cov non-ion siv sijhawm ib teev thiab ib nrab.
4. Los ntawm kev sim dej phwj tuaj, peb txhua tus paub tias cov polyacrylamide cationic polyacrylamide PAM dav dav yog qhov tsim nyog rau cov khoom tsis zoo uas muaj cov organic; anionic PAM yog qhov tsim nyog rau qhov muaj ntau dua ntawm cov khoom tsis muaj zog thiab cov khoom me me uas muaj zog (0.01-1mm), pH tus nqi yog nruab nrab lossis alkaline soluble; non-ionic polyacrylamide PAM yog qhov tsim nyog rau kev sib cais ntawm cov khoom khov kho hauv cov organic thiab inorganic sib xyaw, thiab cov tshuaj yog acidic lossis nruab nrab. Cov flocs tsim los ntawm cationic polyacrylamide yog loj thiab ntom, thaum cov flocs tsim los ntawm anion thiab non-ion yog me me thiab tawg.
