Emulsion yog dav siv hauv zaub mov, tshuaj, tshuaj tua kab, tshuaj thiab lwm yam. Ib txoj hauv kev yooj yim thiab nrawm rau kev txiav txim siab ntawm emulsion stability yog qhov teeb meem kub hauv kev tshawb fawb emulsion. Hauv daim ntawv no, tus kheej-tsim illuminometer txoj kev yog siv los kawm txog kev ruaj ntseg ntawm roj av ether-dej emulsification system. Cov ntsiab lus tseem ceeb ntawm kev tshawb fawb thiab kev ua tiav yog raws li hauv qab no:
1. Ib qho emulsion stability ntsuas ntsuas nrog lub illuminometer raws li tus ntes tau tsim. Nws tuaj yeem siv los ntsuas qhov ruaj khov ntawm cov roj-hauv-dej (0/W) thiab dej-hauv-roj (W/0) emulsions, thiab cov txiaj ntsig ntsuas tau zoo ib yam nrog cov turbidimeter, qhia tias cov cuab yeej tsim los txhim khu kev qha.
2. Ib txoj hauv kev los ntsuas kev ruaj ntseg emulsion tau tsim los ntawm txoj kev illuminometer. Kev ruaj ntseg ntawm emulsion tau soj ntsuam raws li lub sijhawm ntawm kev hloov pauv sai sai ntawm kev siv zog thiab ib nrab-lub neej ntawm emulsion, thiab lub sijhawm ruaj khov ntawm emulsion tau kwv yees.
3. Kev ruaj ntseg ntawm roj-hauv-dej (0/W) thiab dej-hauv-roj (W/0) emulsions npaj los ntawm triton X-100 thiab SPAN{{8} } raws li emulsifiers tau tshawb xyuas raws. Cov teebmeem ntawm cov tshuab stirring txoj kev, ultrasonic txoj kev, ua ke txoj kev (ua ke stirring thiab ultrasonic yoj) thiab emulsification tej yam kev mob ntawm stability ntawm cov mis nyuj kev lag luam tau tham. Cov txiaj ntsig kev sim qhia tau tias, rau cov roj-hauv-dej ({11}}/W) emulsion, cov txheej txheem zoo tshaj plaws rau kev ruaj ntseg yog: emulsification 1515min, emulsification kub 30oC, ultrasonic zog 480W, emulsifier 1.000g Cov emulsion npaj los ntawm Nws yog 5400min thiab lub neej ib nrab yog 5600min. Rau dej-hauv-roj (W/0) emulsion, qhov zoo tshaj plaws stability tej yam kev mob yog: emulsification 30min, emulsification kub 30oC, ultrasonic hwj chim 240W, emulsifier 1.000g emulsion yog lub feem ntau ruaj khov, ruaj khov lub sij hawm thiab ib nrab- lub neej yog 3500 thiab 4130min feem.
4. Tshawb xyuas txoj kev ntsuas emulsion stability los ntawm ntsug scanning txoj kev ntawm illuminometer. Cov teebmeem ntawm emulsification lub sij hawm, qhov kub thiab txias, lub zog ultrasonic, thiab emulsifier concentration ntawm qhov ruaj khov ntawm emulsion tau kawm los ntawm ntsug scanning. Cov txiaj ntsig kev sim tau zoo ib yam nrog cov txiaj ntsig kev ntsuas ntawm qhov kev soj ntsuam ruaj khov. Nws muab lub hauv paus rau kev txhim kho yav tom ntej ntawm cov cuab yeej scanning sai rau kev txiav txim siab ntawm emulsion stability.
