Peb Cov teebmeem ntawm Ultrasonic Wave ntawm Optical Ultrasonic Cleaning Tshuab

1. Mechanical nyhuv

Lub tshuab ua haujlwm ntawm lub tshuab kho qhov muag ultrasonic tuaj yeem txhawb cov emulsification ntawm cov kua, liquefaction ntawm gel thiab dispersion ntawm cov khoom. Thaum sawv nthwv dej yog tsim nyob rau hauv ultrasonic kua nruab nrab, cov me me hais raug tshem tawm nyob rau hauv cov kua yog condensed ntawm lub yoj nodes vim mechanical quab yuam, sib sau ua ntu zus nyob rau hauv qhov chaw. Thaum ultrasonic yoj propagates nyob rau hauv cov ntaub ntawv piezoelectric thiab magnetostrictive cov ntaub ntawv, cov neeg kho tshuab kev txiav txim ntawm ultrasonic yoj ua rau induced polarization thiab induced magnetization.

2. Cavitation

Thaum lub ultrasonic nthwv dej ntawm optical ultrasonic nqus tsev vacuum ua rau cov kua, ib tug loj tus naj npawb ntawm cov npuas me me yuav generated. Ib qho laj thawj yog tias lub zog tensile hauv zos hauv cov kua ua rau lub siab tsis zoo. Qhov txo qis ntawm qhov siab ua rau cov pa roj thaum xub thawj yaj hauv cov kua supersaturated, thiab tom qab ntawd khiav tawm ntawm cov kua los ua npuas me. Lwm qhov laj thawj yog qhov muaj zog tensile kev nyuaj siab "lub kua muag" cov kua rau hauv kab noj hniav, uas yog hu ua cavitation. Cov npuas me me uas tsim los ntawm cavitation yuav txav mus, loj hlob lossis tawg sai sai nrog kev co ntawm qhov nruab nrab ib puag ncig. Thaum tawg, cov kua ib puag ncig dheev rushes mus rau hauv cov npuas ua kom kub, siab siab thiab poob siab yoj.

3. Cov nyhuv tshuaj

Kev ua haujlwm ntawm ultrasonic yoj ntawm lub tshuab kho qhov muag ultrasonic tuaj yeem txhawb lossis nrawm qee cov tshuaj tiv thaiv. Piv txwv li, cov dej ntshiab distilled generates hydrogen peroxide tom qab kho ultrasonic; Nitric acid yog tsim los ntawm nitrogen yaj dej tom qab kev kho mob ultrasonic; Cov tshuaj aqueous ntawm dye yuav hloov xim lossis ploj tom qab kev kho ultrasonic, uas yog ib txwm nrog cavitation. Ultrasound kuj tseem tuaj yeem ua kom cov hydrolysis, decomposition thiab polymerization ntawm ntau cov tshuaj. Ultrasound kuj tseem muaj feem cuam tshuam rau cov txheej txheem photochemical thiab electrochemical.
