Lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev emulsifying
Dec 12, 2023
Ib qho emulsifier yog ib qho khoom siv uas sib xyaw ua ke ob lossis ntau dua immiscible los yog nyuaj rau yaj cov kua rau hauv ib qho zoo thiab ruaj khov emulsion. Nws muaj ntau yam kev siv hauv kev lag luam xws li zaub mov, tshuaj, tshuaj, tshuaj pleev ib ce, thiab lwm yam.
Lub hauv paus ntsiab lus tseem ceeb ntawm lub emulsifier yog shear, sib tsoo, thiab cuam tshuam cov kua los ntawm kev kub ceev rotor los yog cov hniav, kom sib tov thiab sib npaug ntawm ob lossis ntau dua cov kua dej ua ke. Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm emulsifier tuaj yeem raug sau tseg rau hauv cov kauj ruam hauv qab no:
1. Shear action: Lub tshuab tig hauv lub emulsifier tsim lub zog shear los ntawm kev sib hloov ceev, ua rau cov khoom hauv cov kua tawg mus thiab tsim cov shear force field. Lub zog shear no tuaj yeem txiav cov khoom loj lossis cov tee rau hauv cov me me, txhim kho cov nyhuv emulsification.
2. Kev sib tsoo cov nyhuv: Thaum lub sij hawm kev sib hloov ceev, cov khoom los yog cov tee dej hauv cov kua yuav sib tsoo nrog ib leeg, sib cais thiab tawg ntxiv. Kev sib tsoo cov nyhuv txhim kho qhov tawg ntawm cov khoom thiab cov tee dej hauv cov kua, uas yog qhov zoo rau cov txheej txheem emulsification.
3. Cov nyhuv cuam tshuam: Hauv lub tshuab emulsifying, muaj qee qhov kev ncua deb ntawm cov rotating thiab taag qhov chaw, thiab thaum cov kua dhau los ntawm qhov sib txawv, nws yuav raug cuam tshuam los ntawm kev cuam tshuam. Qhov kev cuam tshuam quab yuam no tuaj yeem rhuav tshem cov khoom thiab cov tee dej hauv cov kua, txhawb cov txheej txheem emulsification.
Cov nyhuv emulsification ntawm emulsifier yog cuam tshuam los ntawm ntau yam, nrog rau cov khoom ntawm cov kua, kev sib hloov ceev, thaj tsam cuam tshuam, cuam tshuam qhov sib txawv, thiab lwm yam. Yuav kom xaiv cov qauv zoo tshaj plaws emulsifier, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog cov kev tsim khoom tshwj xeeb thiab qhov yuav tsum tau emulsification nyhuv.
Ntxiv nrog rau cov nyhuv emulsification, nws tseem yuav tsum tau xav txog lub peev xwm ntau lawm, hnav tsis kam, kev huv thiab lwm yam kev xav tau ntawm emulsifier. Cov kev cai rau emulsifiers sib txawv ntawm cov kev lag luam sib txawv, xws li kev lag luam tshuaj, uas muaj cov kev xav tau siab dua rau cov khoom siv emulsifier thiab xav tau cov ntaub ntawv uas tiv taus corrosion thiab kub kub.
Thaum xaiv tus qauv emulsifier, nws tseem yuav tsum tau ua tib zoo xav txog yam xws li kev saib xyuas cov cuab yeej, kev ua haujlwm yooj yim, thiab kev nyab xeeb. Tsis tas li ntawd, tus nqi ntawm emulsifier kuj yog ib qho tseem ceeb rau kev txiav txim siab.
Hauv cov ntsiab lus, los ntawm kev nkag siab lub hauv paus ntsiab lus ntawm emulsifiers, nws muaj peev xwm xaiv cov qauv emulsifier zoo dua uas ua tau raws li cov kev xav tau ntau lawm. Nyob rau hauv cov txheej txheem xaiv, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog yam xws li cov nyhuv emulsification, muaj peev xwm ntau lawm, hnav tsis kam, huv, thiab tu, thiab thaum kawg nrhiav tau lub tshuab emulsification zoo tagnrho uas haum rau koj cov kev xav tau.
