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 tag nrho cov khoom dawb, yuav ua li cas paub qhov txawv ntawm nws cov qauv?
Muaj 4 txoj hauv kev yooj yim kom paub qhov txawv ntawm cov qauv ntawm polyacrylamide:
1. Peb txhua tus paub tias cationic polyacrylamide yog cov kim tshaj plaws nyob rau 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 ntawm hom ion.
2. Dissolve polyacrylamide los ntsuas pH tus nqi ntawm cov tshuaj.Qhov sib thooj pH qhov tseem ceeb ntawm ntau cov qauv sib txawv.
3. Ua ntej, xaiv anionic polyacrylamide thiab cationic polyacrylamide cov khoom, thiab yaj lawv nyias.Sib tov cov khoom siv tshuaj polyacrylamide los kuaj nrog ob txoj kev daws teeb meem PAM.Yog tias nws cuam tshuam nrog cov khoom lag luam anionic polyacrylamide, nws txhais tau tias Polyacrylamide yog cationic.Yog tias nws cuam tshuam nrog cations, nws ua pov thawj tias PAM cov khoom yog anionic lossis tsis-ionic.Qhov tsis zoo ntawm txoj kev no yog tias nws tsis tuaj yeem txheeb xyuas qhov tseeb seb cov khoom puas yog anionic lossis non-ionic polyacrylamide.Tab sis peb tuaj yeem txiav txim siab los ntawm lawv lub sijhawm tawg, anions yaj sai dua li cov tsis-ions.Feem ntau, cov anion yog yaj tag rau hauv ib teev, thaum lub non-ion yuav siv sij hawm ib thiab ib nrab teev.
4. Inferred los ntawm kev sim dej phwj tuaj, peb txhua tus paub tias cov khoom siv polyacrylamide cationic polyacrylamide PAM yog tsim rau cov teeb meem tsis zoo uas muaj cov khoom siv organic;anionic PAM yog tsim rau ntau dua concentration ntawm qhov zoo nqi inorganic suspended teeb meem thiab tshem tawm hais coarse (0.01-1mm), pH nqi yog nruab nrab los yog alkaline soluble;non-ionic polyacrylamide PAM yog tsim rau kev sib cais ntawm cov khib nyiab pov tseg hauv lub xeev sib xyaw ntawm cov organic thiab inorganic, thiab cov tshuaj yog acidic lossis nruab nrab.Cov flocs tsim los ntawm cationic polyacrylamide yog loj thiab ntom, thaum lub flocs tsim los ntawm anion thiab non-ion yog me me thiab tawg.
