Cov khoom siv yas yog cov khoom siv dav siv hauv kev lag luam niaj hnub.Txawm li cas los xij, vim lawv cov khoom tshwj xeeb, cov khoom siv yas sib txawv muaj qhov sib txawv rau kev ua ultrasonic.
Ua ntej, peb yuav tsum nkag siab tias kev ua ultrasonic yog dab tsi.Ultrasonic ua siv ultrasonic zog generated los ntawm high-frequency kev co los co cov khoom molecules nyob rau saum npoo ntawm lub workpiece, ua rau nws mos thiab ntws, yog li ua tiav lub hom phiaj ntawm kev ua.Cov thev naus laus zis no muaj qhov zoo ntawm kev ua haujlwm siab, precision, tsis muaj kev puas tsuaj thiab kev tiv thaiv ib puag ncig, yog li nws tau siv dav hauv cov txheej txheem tsim khoom.
Txawm li cas los xij, cov khoom sib txawv thiab cov khoom ntawm cov ntaub ntawv yas cuam tshuam rau lawv qhov tsim nyog rau kev ua ultrasonic.Piv txwv li, polyethylene (PE) thiab polypropylene (PP), ob qho khoom siv dav siv, yog tsim rau kev ua ultrasonic.Vim tias lawv cov qauv molecular yog qhov yooj yim, tsis muaj qhov pom tseeb molecular cross-links thiab polar chemical pawg.Cov yam ntxwv no tso cai rau ultrasonic tsis yooj yim nkag mus rau hauv cov yas nto thiab ua rau kev co ntawm cov khoom molecules, yog li ua tiav lub hom phiaj ntawm kev ua.
Txawm li cas los xij, lwm cov ntaub ntawv polymer xws li polyimide (PI), polycarbonate (PC) thiab polyamide (PA) tsis haum rau kev ua ultrasonic.Qhov no yog vim hais tias cov qauv molecular ntawm cov ntaub ntawv no yog complex, nthuav ntau dua molecular cross-linking thiab polar chemical pawg.Ultrasonic nthwv dej yuav raug cuam tshuam rau hauv cov ntaub ntawv no, ua rau nws nyuaj ua rau kev co thiab ntws ntawm cov khoom molecules, ua rau nws tsis yooj yim sua kom ua tiav cov hom phiaj.
Tsis tas li ntawd, qee yam tshwj xeeb ntawm cov ntaub ntawv yas xws li tawv polyvinyl chloride (PVC) thiab polystyrene (PS) tsis haum rau kev ua ultrasonic.Qhov no yog vim hais tias lawv cov qauv molecular yog cov nkig thiab tsis tuaj yeem tiv taus lub zog muaj zog vibration uas tsim los ntawm ultrasonic tsis, uas tuaj yeem yooj yim ua rau cov khoom tawg lossis tawg.
Txhawm rau ua kom tiav, ntau hom khoom siv yas muaj qhov sib txawv rau kev ua ultrasonic.Thaum xaiv ib txoj kev tsim nyog, cov khoom muaj pes tsawg leeg thiab cov khoom ntawm cov khoom yuav tsum tau txiav txim siab los xyuas kom meej qhov ua tiav ntawm kev ua tiav.
