Yam dab tsi yuav cuam tshuam rau qhov zoo ntawm ultrasonic vuam?
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab ultrasonic welding yog siv lub siab-ntau qhov kev co tsim los ntawm ultrasonic nthwv dej los ua cov khoom ua haujlwm los txhawb cov khoom sib txuas ntawm ob cov khoom siv polymers, yog li ua tiav cov nyhuv ntawm cov khoom siv fusion. Muaj ob qho cuam tshuam uas cuam tshuam rau lub vuam zoo ntawm tshuab vuam ultrasonic, uas yog lub npe thiab ntau zaus.
1. Amplitude
Cov hloov khoom sib txawv muaj cov tso zis sib txawv. Feem ntau, qhov tso zis ntau ntxiv ntawm qhov transducer ntawm lub tshuab ultrasonic hlau vuam yog feem ntau 5-20 microns, thiab qhov ua haujlwm loj yog 10-30 microns. Lub tshuab raj, lub cev ntawm lub vuam taub thiab tso tawm qhov tso zis yog yam uas txiav txim siab ua haujlwm loj ntawm qhov hloov pauv. Lub tshuab nqus hlau ultrasonic txuas cov khoom siv los ntawm hom kev hloov txav no, yog li cov amplitude ncaj qha cuam tshuam rau qhov zoo ntawm vuam.
2. Zaus
Txhua lub tshuab ua vuam nws muaj nws qhov chaw zaus, thiab txhua zaus sib txawv, qhov teeb meem vuam kuj tseem yuav sib txawv. Kev ua haujlwm nquag ntawm lub vuam tshuab yog txiav txim siab los ntawm lub tshuab resonance zaus ntawm ultrasonic transducer, lub tshuab raj thiab lub taub hau vuam. Vim tias ultrasonic tshuab muaj qhov zoo vuam ntawm cov ntaub ntawv, kub phaj vuam tshuab yog maj hloov nyob rau hauv kev lag luam luam ntawv. Thaum ua lub vuam sib txuas tshiab, tib neeg yuav tsum kho cov teeb meem pheem kom rov ua kom qhov yuam kev ntawm qhov hloov dua tshiab, thiab qhov yuam kev tsim zaus tsis dhau 0.1kHz. Tam sim no, qhov zaus ntawm ultrasonic hlau vuam yog feem ntau 20kHz, thiab qhov kev ua yuam kev tsawg dua 5%.
Hauv txoj kev hais, qhov ntau thiab ntau zaus cuam tshuam ncaj qha rau vuam zoo ntawm lub tshuab vuam ultrasonic, yog li thaum peb nyob hauv kev vuam, peb yuav tsum ua ob yam no los mus rau kev txiav txim siab kom paub tseeb tias lub vuam zoo ntawm lub tshuab ultrasonic welding.
