Ntsiab Cai ntawm Ultrasonic Emulsification
Raws li qhov kev txiav txim ntawm lub zog ultrasonic, ob lossis ntau dua kua tshuaj tsis tau sib xyaw ua ke. Ib qho ntawm cov kua kuj tseem sib npaug ntawm cov kua dej, tsim cov kua hluav taws xob zoo li kua. Cov txheej txheem no hu ua ultrasonic emulsification.
Phacoemulsification yog tshwm sim los ntawm cavitation. Ultrasound dhau los ntawm cov kua ua rau nws txuas ntxiv zaws thiab nthuav. Muaj zog siv hluav taws xob ultrasound muab lub zog xav tau txhawm rau tawg cov theem kua. Thaum lub siab tshaj plaws tau mus txog, ua kua tawg tshwm sim ntawm qhov chaw uas sib koom ua ke tsis muaj zog. Tom qab qhov kev txhim kho, tawg dhau nyob ntawm qhov chaw uas sib tsoo, thiab qee qhov kab noj hniav tau pom. Hauv cov voids no, cov roj ua kua-tawg tau tawg rau hauv daim ntawv ua npuas sai tom qab.
Txhawm rau ruaj khov tshiab tsim dispersed theem mob los tiv thaiv coalescence, emulsifiers (surfactants, surfactants) thiab stabilizers ntxiv rau emulsion. Qhov kawg ntawm qhov xa me me rov qab tau tswj nyob rau tib theem li thaum cov tee tau faib hauv thaj chaw ultrasonic dispersion.
Cov txheej txheem cavitation cuam tshuam los ntawm ntau zaus thiab siv ntawm cov vuam ultrasonic. Qhov tshwm sim ntawm cavitation hauv lub cev yog nyob ntawm ntau ntawm qhov tsis muaj roj nyob hauv cov kua tshem tawm. Lub xub ntiag ntawm cov roj zoo li ua lub luag haujlwm tsim kev tswj hwm. Raws li qee qhov siab, qhov tsim ntawm tus kab noj hniav yog nyob ntawm qee qhov ntawm lub sijhawm txhim kho thiab qhov tsawg zaus ntawm ultrasound. Cov txheej txheem phacoemulsification sawv cev rau kev sib tw ntawm cov txheej txheem tawm tsam. Yog li, nws yog ib qho tsim nyog yuav tsum xaiv cov haujlwm ua haujlwm tsim nyog thiab zaus kom cov kev puas tsuaj cuam tshuam kom muaj yeej.
Ultrasonic cavitation nyhuv
Txhawm rau npaj cov roj-hauv-dej emulsion, lub suab qhov kawg siv yog ntau qis dua li ntawm cov dej-hauv-roj emulsion. Lub suab ntim cuam tshuam cuam tshuam cov txheej txheem emulsification, uas yog, qee yam taug kev nthwv dej yog thov. Piv nrog rau daim ntawv thov ntawm qee lub vuag nyob ruaj ruaj, cov txheej txheem ua kom zoo dua. Qhov no tuaj yeem piav qhia los ntawm qhov tseeb tias nyob rau hauv thaj chaw ib nthwv dej, cov txheej txheem rov qab mus rau kev tawg, uas yog, hws yog hom.
