Nyob rau hauv cov txheej txheem ntawm cov khoom yas, ultrasonic vuam tshuab tuaj yeem kaw cov khoom yas sai thiab ua tau zoo.Tsis tas li ntawd, nyob rau hauv cov txheej txheem ntawm sealing, nws tsis tas yuav tsum muaj cov khoom siv hluav taws xob sab nraud los yog tsis xav tau cov flux, cov nyhuv vuam zoo heev thiab vuam lub zog kuj yog siab heev.Thaum lub sij hawm ultrasonic vuam tshuab nyob rau hauv daim ntawv thov txheej txheem, cov yam ntxwv ntawm tus nqi qis thiab kev ruaj ntseg siab kuj ua rau nws yog dav siv nyob rau hauv yas machinery khoom, ntawv sau, kev lag luam pleev, khoom ua si kev lag luam, hluav taws xob kev lag luam.
1. Ultrasonic yas vuam tshuab thiab nws cov yam ntxwv
1. 1 Ultrasonic yas vuam tshuab
Ultrasonic yas vuam tshuab yog vuam cov khoom yas ua ke los ntawm ultrasonic vibration txoj cai.Thaum lub ultrasonic yoj siv los welding cov yas welds, kev sib txhuam yuav tshwm sim ntawm cov molecules nyob rau hauv lub ultrasonic yoj thiab kev sib cuag nto ntawm cov khoom yas, thiab ces qhov kub ntawm lub vuam ntawm cov yas welding nto sai sai mus txog lub melting point ntawm cov khoom. yas.Lub sijhawm no, cov yaj ntawm ob lub welds yas yuav ntws ua ke.Thaum cov molecules nyob rau hauv lub ultrasonic yoj nres vibrating, cov yas yaj yog raug rau siab thiab sai sai solidifies thiab crystallizes, ua lub weld txawm.Lub zog ntawm qhov chaw vuam yog ze rau ntawm cov khoom siv raw.Txhawm rau txhawm rau vuam cov khoom siv yas ua ke, nws yog ib qho tsim nyog los xyuas kom meej tias cov cua sov tsim los ntawm ultrasonic yoj tuaj yeem tshwm sim hauv thaj chaw vuam, thiab cov qauv coj lub zog coj los siv yuav tsum tau siv los hloov thiab coj cov cua sov tsim los ntawm ultrasonic yoj, thiab lub zog taw qhia qauv kuj hu ua vuam hlau qauv.
1.2 Yam ntxwv ntawm ultrasonic yas vuam tshuab
Ultrasonic yas vuam tshuab tsuas yog tsim rau cov thermoplastics, thiab rau lwm cov ntaub ntawv tsis haum rau kev siv.vim li cas thiaj xaiv cov thermoplastics yog tias cov khoom siv tshuaj thiab lub cev ntawm cov thermoplastics tseem tsis hloov thaum lawv yaj thiab tom qab ntawd kho.Thermoplastics tuaj yeem muab faib ua crystalline thiab amorphous raws li lawv cov khoom.Ntawm lawv, lub melting point ntawm crystalline yas yog pom tseeb, thiab nws cov molecules nyob rau hauv lub molecules yuav tsum tau teem nyob rau hauv raws li cov kev cai sib raug zoo thaum kho mus rau lub siv lead ua cheeb tsam.
