Yuav tsum Muaj Ultrasonic Vuam Ntawm Cov Khoom Siv Vuam
Sep 09, 2022
Lub hauv paus ntsiab lus ntawm ultrasonic welding yog tsuas yog hais tias lub tshuab ultrasonic xa tawm cov zaus zaus ua rau ob daim ntawv sib koom ua ke tsim qhov siab tshaj plaws amplitude. Thaum cov zaus xa tawm yog ua raws li lub ntuj zaus ntawm cov khoom, qhov amplitude yog qhov loj tshaj plaws. Qhov no amplitude tsav lub molecules (los yog molecular chains) nyob rau hauv cov khoom kom vibrate ntau yog, ua rau instantaneous kub kub, uas ua rau ob qho tib si cov ntaub ntawv yuav tsum tau sib txuas ua ke thaum lub sij hawm txias txheej txheem.
Raws li cov txheej txheem tam sim no, feem ntau ntawm cov ntaub ntawv uas feem ntau siv rau ultrasonic vuam yog cov ntaub ntawv polymer, xws li PMMA, ABS PC, thiab lwm yam. ultrasonic yoj
1. Nws yog ib qho tsim nyog yuav tsum to taub qhov weldability ntawm cov ntaub ntawv yuav tsum tau welded. Qee cov ntaub ntawv nyuaj rau vuam, thaum lwm tus tsis yog. Cov yas tau muab faib ua cov thermosetting thiab cov khoom siv thermoplastic. Cov khoom siv thermosetting yuav tsum tsis txhob welded. Cov ntaub ntawv thermoplastic tau muab faib ua cov khoom siv amorphous (xws li ABS) thiab cov khoom siv crystalline semi (xws li PET / PBT). Amorphous cov ntaub ntawv yog ib qho yooj yim rau welded los ntawm ultrasonic tsis, thaum semi crystalline cov ntaub ntawv yog ib qho nyuaj rau welded. Thov xa mus rau daim ntawv qhia.
2. Ua tib zoo saib xyuas cov txheej txheem ua ntej ntawm welded yas qhov chaw. Qee cov ntaub ntawv yuav muaj cov khoom siv ntxiv thaum txhaj tshuaj molding, xws li iav fiber ntau, talc hmoov, thiab lwm yam. Thiab ua tib zoo saib seb cov dej noo ntawm cov khoom puas txaus kom qhuav, thiab lwm yam ... cov teeb meem tshwj xeeb yog kho tshwj xeeb.
3. Cov yam ntxwv ntawm qhov vuam: feem ntau, muaj cov qauv tsim, xws li cov thawj coj ntawm lub zog thiab kev sib koom ua ke. Feem ntau, hom pib yog muab faib ua ntaiv hom tsim thiab tenon groove hom tsim. Shenzhen jiayuanda tuam txhab tuaj yeem muab koj nrog kev cob qhia thiab kev pabcuam.
