Txij li thaum 90s thaum ntxov, peb tus muam lub tuam txhab SONIMAT tau txais lub sijhawm ntev thiab kev nplua nuj nyob hauv kev siv cov thev naus laus zis hauv kev sib dhos, vuam thiab txiav daim ntawv thov.
Ultrasound yog zoo ib yam li cov neeg kho tshuab kev co uas ua los ntawm cov twj paj nruag. Cov kev co no yog hu ua ultrasonic tsis muaj zog vim tias lawv cov zaus ntau dua li tib neeg pob ntseg (ntau dua 16 kHz). Cov kev ntsuas cua siab no yog tsim los ntawm lub tshuab hluav taws xob.
Qhov ntau zaus ntawm kev hloov tam sim no uas tsim los ntawm lub tshuab hluav taws xob yog tib yam li lub zaus ntawm lub zog hloov (lossis hloov khoom) tsim ntawm piezoelectric ceramics thiab hloov nws mus rau kev siv tshuab kev co. Lub tshuab xa hluav taws xob raug xa ntawm cov pob zeb (ceramic), uas" ncav" lossis" ua kom qis" raws li qhov polarity ntawm qhov ntsuas hluav taws xob. Thaum tsim qhov kev co tawm, nws tau nthuav dav thiab kis mus rau qhov yuav tsum tau welded lossis txiav los ntawm ultrasonic vuam electrode.
Lub tshuab hluav taws xob hloov hluav taws xob tsawg (50/60 Hz) rau hauv qhov loj cov hluav taws xob hluav taws xob, uas sib npaug rau 20000 Hz hauv cov qauv no.
Piezoelectric transducers (lossis hloov chaw) hloov mus rau 20000 Hz hluav taws xob rau kev siv tshuab kev co ntawm tib zaus. Lub zog tom qab ntawd ua tshuab.
Lub rooj zaum txhawb lossis ntxiv zog yuav ntxiv nce lossis txo cov ntaj tsim tawm los ntawm lub zog hloov pauv. Lub caij kawg ntawm cov cim sonic, lub tshuab hluav taws xob ultrasonic, xa cov ultrasonic zog rau ib feem kom txiav.
Hauv cov txheej txheem ultrasonic txiav, lub tshuab hluav taws xob ultrasonic tseem hu ua cutter. Tau txais 20,000 deeg ib pliag, lub tshuab txiav ultrasonic no yuav tsum tau siv zog tsawg dua thiab tuaj yeem txiav cov ntaub ntawv sib xyaw thiab cov khoom siv honeycomb.
