Yam cuam tshuam rau kev ua tau zoo ntawm ultrasonic yas vuam tshuab
1. Vuam nrug
Ultrasonic welding tuaj yeem muab faib ua ze-tsawg vuam thiab nyob deb-tsav vuam. Nyob ze qhov chaw vuam yog hais txog qhov kev ncua deb ntawm qhov sib txuas ntawm cov yas thiab qhov kawg ntawm lub caj npab electrode nyob rau hauv 6 hli, thiab tshaj qhov kev ncua deb yog suav hais tias nyob deb welding. Rau amorphous nyuaj plastics xws li PC, PS, SAN, ABS, thiab PMMA, lawv feem ntau muaj emissivity zoo rau ultrasonic zog thiab xa high-frequency vibration zog nyob rau hauv ntev mus rau lub interface cheeb tsam. Yog li ntawd, cov ntaub ntawv no muaj kev ua haujlwm zoo heev ntawm kev sib tw nyob ze thiab deb. Rau semi crystalline plastics, lawv cov suab nrov attenuation kuj muaj zog. Kev vibration siab yog kis mus rau semi crystalline plastics xws li PA, PP, PE, thiab POM, thiab lub zog ultrasonic yuav sai sai. Yog li ntawd, semi crystalline plastics tsuas yog siv nyob rau hauv ze-tsav vuam. Rau elastomers thiab cov yas mos, cov nyhuv ntawm ultrasonic vuam tsis yog qhov tseem ceeb vim lawv lub suab nrov dua.
2. Ultrasound zog noj:
Los ntawm qhov kev xav ntawm lub zog noj, vim hais tias amorphous plastics tsis muaj qhov tseeb melting point, lub tshav kub yuav tsum tau rau plasticization, piv txwv li ultrasonic zog, yuav kuj tsawg. Raws li qhov kub ntawm qhov chaw vuam nce, cov khoom yuav maj mam hloov los ntawm lub siab elasticity mus rau lub viscous flow xeev, thiab tseem tuaj yeem yaj thiab maj mam solidify ntau qhov kub thiab txias. Ntxiv mus, semi-crystalline plastics muaj cov ntsiab lus meej melting thiab xav tau ntau dua melting kub. Piv nrog rau amorphous polymers, lawv xav tau ntau dua ultrasonic zog thiab amplitude hloov thaum vuam.

3. Qhov cuam tshuam ntawm cov khoom siv ntxiv thiab cov roj stains ntawm cov khoom yas:
Txhawm rau kom ntseeg tau qhov zoo ntawm cov khoom siv welded, tag nrho cov kev txiav txim siab yuav tsum tau muab rau cov khoom thiab kev ua haujlwm kawg ntawm cov khoom siv raw uas yuav tsum tau ua ua ntej. Tsis tas li ntawd, cov khoom siv ntxiv xws li cov roj nplua nyeem thiab cov nplaim hluav taws kub hnyiab muaj nyob rau hauv cov yas kuj tuaj yeem cuam tshuam rau kev sib txuas ntawm cov khoom siv. Yog li ntawd, nyob rau hauv cov khoom tsim thiab vuam parameter hloov, tag nrho cov kev xav yuav tsum tau muab. Thaum kawg, lub interface yuav tsum tau tsim kom raug los ntawm kev ntsuam xyuas los tiv thaiv pwm hloov tom qab ua tiav cov khoom molding. Thiab xyuam xim rau tus neeg sawv cev tso tawm thiab cov roj stains hauv qhov chaw vuam, uas tuaj yeem txo lub zog ntawm vuam. Nws yog ib qho tsim nyog los ntxuav qhov chaw ntawm pwm kab noj hniav nyob rau hauv ib lub sij hawm.
4. Kev cuam tshuam ntawm cov khoom siv yas:
Ultrasonic vuam yog tsim nyog rau daim ntawv thov nyob rau hauv ib tug nyuaj amorphous plastics, thiab cov nyhuv zoo tshaj plaws yog tiav thaum txuas tib lub yas. Ob hom yas, xws li polycarbonate thiab acrylic acid, nrog lub melting kub sib txawv ntawm li 20 degree thiab tej yam compatibility nyob rau hauv tshuaj lom neeg cov khoom.
