Polyaluminium chloride (PAC) yog ib qho kev kho decolorization zoo heev rau cov dej khib nyiab tau los ntawm cov kua dej ntau lawm. Syrup yog ib qho khoom qab zib uas tau dhau los ua ib feem ntawm peb lub neej txhua hnub.
Vim muaj kev txwv tsis pub siv cov khoom noj ntxiv hauv ntau lub tebchaws nyob rau xyoo tas los no, feem ntau ntawm cov syrups hauv kev lag luam khoom noj khoom haus yog ua los ntawm pob kws, qos yaj ywm los yog nplej es tsis txhob siv cov qab zib ntau dua. Ua li no, cov kua dej npaj yuav muaj qee cov hmoov txhuv nplej siab thiab ntau cov piam thaj tsis huv, yog li nws yuav tsum tau decolorized.
Tam sim no, feem ntau ntawm cov khoom noj khoom haus hauv tsev feem ntau siv flocculants xws li polyaluminum chloride, polyferric sulfate, thiab polyacrylamide los decolorize syrup. Cov kev sim qhia tau hais tias kev kho decolorization nyhuv ntawm polyaluminium chloride yog qhov zoo tshaj plaws. Vim tias polyaluminium chloride flocculant yog cationic polymer flocculant, thiab muaj cov yam ntxwv ntawm ntuj, tsis muaj tshuaj lom thiab muaj kev nyab xeeb zoo. Yog li ntawd, nws tau siv dav hauv cov txheej txheem decolorization ntawm cov kua qab zib hauv xyoo tas los no, thiab tau ua tiav cov txiaj ntsig zoo.
Kev tshawb fawb xaus lus tias qhov zoo tshaj plaws ntawm polyaluminium chloride flocculant yog 300mg / kg, qhov piv ntawm PAC: CTS yog 2: 4, pH yog 6.2, qhov kub thiab txias yog 75 degree, thiab lub sij hawm yog 8min.
