Yuav ua li cas kom ua tiav cov roj-dej sib npaug hauv cov kua dej ntawm emulsion tshuab

Raws li rau "sib npaug ntawm cov roj degree" nyob rau hauv lub emulsified txiav kua, cov kua txiav npaj los ntawm emulsified homogenizer yuav muab faib ua peb pawg: hom roj ntshiab, emulsified hom thiab tag nrho cov khoom hluavtaws raws li nws cov qauv qauv, uas yog hu ua txiav cov roj, emulsified txiav kua thiab tag nrho cov hluavtaws txiav kua raws.

500L lifting external circulation homogenizing emulsification homogenizer.

Yuav ua li cas kom ua tiav cov roj-dej sib npaug hauv cov kua dej ntawm lub tshuab emulsion? Muaj peb hom kev sib xyaw ua ke uas muaj roj, dej thiab surfactant: emulsion, microemulsion, yaj micelle thiab rov qab micelle tov (so micelle tov, feem ntau cov khoom muaj nyob rau thawj ob hom, thiab ob peb cov khoom siv roj tsawg yog rau hom thib peb.

Cov dej ntsiab lus hauv cov roj emulsified feem ntau tsawg dua 10 feem pua, cov roj cov ntsiab lus zui yog siab li 80 feem pua, thiab cov concentrated tov yog hom W/O. Tsuas yog thaum lub kaw lus muaj tus nqi qis HLB nws tuaj yeem ruaj khov. Cov tsos ntawm emulsion diluent feem ntau yog milky dawb thiab tsis ci. Qhov txoj kab uas hla ntawm cov txheej txheem dispersed roj tee yog hais txog 0.1 ~ 10um, thiab pom lub teeb wavelength yog 0.4 ~ 0.8um. Yog li ntawd, lub reflection ntawm lub teeb nyob rau hauv lub emulsion yog qhov tseem ceeb.

Tsis tas li ntawd, qhov kev txwv qis (txog {{0}}.1um) ntawm qhov loj ntawm cov roj emulsified dav dav yog ze rau qhov kev daws teeb meem (kwv yees li 0.2um) ntawm lub tshuab tsom iav.

Lub microemulsion roj-dej cov ntsiab lus tuaj yeem siab li 30 ~ 60 feem pua, thiab cov ntsiab lus roj feem ntau tsawg dua lossis sib npaug li 30 feem pua. Nws cov concentrated tov yog hom O / W, cov diluent feem ntau yog cov kua pob tshab, thiab txoj kab uas hla ntawm cov roj tee feem ntau yog 0.05 ~ 0.1um- Cov dej ntsiab lus ntawm qee cov microemulsions nrog roj cov ntsiab lus ntawm ntau tshaj 50 feem pua. kuj raug txo kom tsawg dua 20 feem pua. Cov tshuaj concentrated yog W / O hom, thiab cov diluent yog xiav dawb translucent kua. Nws yog kev hloov pauv emulsion (me me emulsion) nrog cov roj tee loj ntawm cov emulsion zoo tib yam thiab microemulsion, thiab cov tee me me yog 0.1 ~ 0.4um.
