Dab tsi yog txoj hauv kev ua haujlwm ntawm ultrasonic homogenizer

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ultrasonic homogenizer yog siv cov nyhuv cavitation thiab lwm yam teebmeem ntawm lub cev ntawm ultrasound hauv cov kua kom ua tiav homogenization. Cov nyhuv cavitation yog hais txog kev tsim cov qhov lossis cov npuas me hauv cov dej tsis muaj zog hauv qab kev txiav txim ntawm ultrasound. Cov npuas me me ua raws li cov mem tes ntawm ultrasound thiab vau nyob rau hauv ib lub voj voog suab. Ultrasonic cavitation tseem tuaj yeem ua rau muaj zog txhua yam cuam tshuam, ua cov dav hlau nrawm lossis acoustic impulses ze ntawm cov khoom sib cuam tshuam thiab muaj zog poob siab tsis nyob hauv cov kua. Cov teebmeem ntawm lub cev xa mus rau qhov zoo agitation thiab ntws ntawm ultrasonic nthwv dej hauv cov kua, uas tuaj yeem ua rau cov qauv ntawm qhov nruab nrab thiab tsoo cov khoom hauv cov kua. Cov no feem ntau tshwm sim los ntawm kev sib tsoo ntawm cov kua dej, microphase ntws, thiab kev poob siab tsis muaj zog, ua rau muaj kev hloov pauv hauv qhov chaw morphology ntawm cov khoom.

Ua hauj lwm hauv paus ntsiab lus ntawm ultrasonic homogenizer
1. tiam thiab propagation ntawm ultrasound
Ultrasonic homogenizer feem ntau muaj peb ntu: ultrasonic vibration Cheebtsam, ultrasonic tsav fais fab mov, thiab cov tshuaj tiv thaiv kettle. Lub ultrasonic vibration Cheebtsam feem ntau muaj xws li high-power ultrasonic transducers, amplitude converters, thiab lub taub hau (emitters), uas yog siv los tsim ultrasonic kev co thiab emit lub zog vibration rau hauv cov kua. Lub transducer converts cov input hluav taws xob lub zog rau hauv txhua yam zog, uas yog ultrasonic tsis. Ultrasound lov ua ntau cov npuas me me hauv cov kua ntawm lub vibration zaus ntawm ntau pua txhiab zaus hauv ib ob.

2. Qhov tshwm sim ntawm cavitation nyhuv
Raws li qhov kev txiav txim ntawm ultrasound, cov npuas me me tsim hauv cov kua uas vibrate ntau pua txhiab zaus hauv ib ob. Cov npuas no, nyob rau hauv kev ua haujlwm tas mus li, yuav loj hlob sai sai thiab tom qab ntawd mam li kaw, ua rau muaj zog txaus ntshai nthwv dej uas ua rau muaj kev kub ntxhov ntawm ntau txhiab tus huab cua thiab hauv zos kub nyob ib ncig ntawm cov npuas. Qhov tshwm sim ntawm lub cev no hu ua ultrasonic cavitation nyhuv.

3. Kev siv cov nyhuv cavitation
Cov nyhuv cavitation ntawm ultrasound tuaj yeem tsis tsuas yog txhawb nqa lossis txhawb nqa ntau cov tshuaj tiv thaiv, ua kom cov tshuaj lom neeg muaj zog, tab sis kuj hloov cov kev taw qhia ntawm cov tshuaj tiv thaiv, ua rau qee qhov teebmeem. Thaum lub sij hawm homogenization txheej txheem, cov nyhuv cavitation ntawm ultrasound ua npuas nyob rau hauv cov kua kom maj mam nthuav thaum lub sij hawm tsis zoo siab ib nrab voj voog, cog lus maj mam tab sis tsis rupture thaum lub sij hawm zoo siab ib nrab voj voog, thiab cov npuas nyob rau hauv lub sij hawm thiab tsis-linear oscillation suab, ua rau. nyob rau hauv muaj zog mechanical teebmeem xws li poob siab tsis.

4. Kev siv cov nyhuv homogenization
Los ntawm txoj kev no, ultrasonic homogenizers tuaj yeem ua tau zoo emulsify, cais, disperse, homogenize, degass, huv si, thiab ceev cov tshuaj tiv thaiv. Nws tuaj yeem siv rau kev sib tsoo ntawm cov tsiaj thiab cov ntaub so ntswg, hlwb, cov kab mob, cov kab mob spores, nrog rau kev txiav thiab crushing ntawm cov khoom hauv cov tshuaj, yog li ua tiav homogenization.
