Nws tuaj yeem suav hais tias yog ib hom tshuaj flocculate, tshuaj decolor lossis coagulant.
PAC yog cov polymers inorganic uas yaj tau hauv dej ntawm ALCL3 thiab AL(OH)3, cov mis tshuaj yog [AL2(OH)NCL6-NLm], 'm' txhais tau tias qhov dav ntawm polymerization, 'n' sawv cev rau qib nruab nrab ntawm cov khoom PAC.

Muaj pes tsawg hom PAC?
Muaj ob txoj kev tsim khoom: ib qho yog ziab nruas, qhov thib ob yog ziab tshuaj tsuag. Vim muaj ntau txoj kab tsim khoom sib txawv, muaj qhov sib txawv me ntsis ntawm ob qho tib si tsos thiab cov ntsiab lus.
Cov PAC ziab nruas yog cov hmoov daj lossis xim daj tsaus, nrog cov ntsiab lus ntawm Al203 txij li 27% txog 30%. Cov khoom tsis yaj hauv dej tsis pub ntau tshaj 1%.
Thaum Tshuaj Tsuag Kom Qhuav PAC yog xim daj, daj ntseg lossis dawb hmoov, nrog cov ntsiab lus ntawm AI203 txij li 28% txog 32%. Cov khoom tsis yaj hauv dej tsis ntau tshaj 0.5%.
Yuav ua li cas xaiv PAC kom raug rau kev kho dej sib txawv?
Tsis muaj lus txhais rau kev siv PAC hauv kev kho dej. Nws tsuas yog tus qauv ntawm PAC specifcation xav tau kev kho dej tsis muaj kev cuam tshuam. Tus qauv No. rau kev kho dej haus yog GB 15892-2009. Feem ntau, 27-28% PAC yog siv rau kev kho dej tsis haus, thiab 29-32% PAC yog siv rau kev kho dej haus.
