Dab tsi yog cov kev vuam sib txuas rau cov khoom ua si yas?
Thaum nws tawm los rau yas, txhua tus neeg paub txog nws. Los ntawm cov menyuam yaus' s cov khoom ua si coj mus rau cov thawv ntim khoom siv, los ntawm lub koos pij tawj rau cov khoom siv hauv tsheb, txij li cov menyuam txhuam hniav rau cov dav hlau, cov khoom yas tuaj yeem pom txhua qhov chaw hauv peb lub neej.
Lub npe lus Askiv ntawm yas" yas" los ntawm Greek lo lus" plastikos", uas txhais tau hais tias" tsim" ;," tsim", thiab" Nws yog feem ntau siv los ua qhov chaw, ua rau lo lus" yas" ;. Lub ntsiab lus qub ntawm Suav cim" Yas" txhais tau tias" los siv av los zom cov tib neeg daim duab" ;," plasticity" txuas ntxiv rau txhais" dawb do zoo li", thiab" yas" yog ib cov khoom siv nrog plasticity.
Kev txhaj tshuaj molding yog qhov feem ntau siv txoj hauv kev ua cov yas. Hom qauv no haum rau txhua qhov thermoplastics thiab qee qhov thermosetting plastics, thiab tus lej ntawm cov khoom yas tsim cov khoom lag luam tsis zoo li lwm txoj kev molding. Raws li ib qho ntawm cov cuab yeej tseem ceeb ntawm kev txhaj tshuaj molding ua, kev txhaj tshuaj pwm muaj qib qis ntawm qhov tseeb, kev tsim kho lub voj voog thiab kev tsim khoom hauv cov txheej txheem txhaj tshuaj molding. Thaum cuam tshuam ncaj qha rau cov khoom zoo, cov txiaj ntsig tsim tawm, cov nqi thiab cov khoom hloov tshiab, nws tseem txiav txim siab lub tuam txhab Kev muaj peev xwm teb thiab nrawm hauv kev sib tw ua lag luam.
Hauv cov txheej txheem ntau lawm, plastics uas hla los ntawm kev txhaj tshuaj pwm txawv feem ntau welded. Yog li, dab tsi vuam cov txheej txheem rau cov khoom ua si yas?
1. Kub phaj vuam
Yas qho khoom ua si kub phaj vuam tshuab nta: yooj yim, haum rau vuam chaw loj ntawm cov yas. Siv lub tshuab hluav taws xob cua sov kom ua kom kub sai rau ob sab uas yuav tsum tau txais. Tom qab tshem cov phaj hluav taws xob cua sov, siv lub siab kom fuse cov plastics ntawm ob sab thiab txias kom tiav qhov vuam. Kev tsis zoo: Lub voj voog ntev, cov yas yooj yim los lo rau phaj cua sov, nws tsis yooj yim los ntxuav, thiab cov pa phem loj.
2. Cov cua kub vuam
Nta: Sib dua, tab sis nyuaj rau kev khiav lag luam. Cov huab cua kub melts vuam hlau ntawm tib cov ntaub ntawv ntawm lub vuam seam ua kom tiav vuam.
3.Pulse welding
Crimping ob qho kev ua yeeb yaj kiab, siv Ni-Cr alloy hlau xaim los tsim hluav taws xob kub kom tiav qhov chaw vuam
4. Kev sib txhuam thaum tsim tawm thaum lub sijhawm ua rau tag nrho cov kev sib txhuam ntawm ob feem ntawm kev sib txhuam vuam vuam vias hauv qab lub siab ua haujlwm ua rau cov yas ua kov ib feem ntawm nws melts thiab muag muag, thiab cov kev sib dhos yog tsau kom txog thaum nws ua tiav thiab khov kho.
5.Ultrasonic vuam
Lub tshuab ultrasonic ua si vuam siv lub tshuab siab siv lub tshuab hluav taws xob kom mos muag los yog yaj cov thermoplastic ntawm qhov sib koom ua ke.
Thaum cov ntu txuas nrog kho los ntawm lub siab, thiab qhov zaus feem ntau yog 20-40 kHz ultrasonic kev co, lub tshuab hloov pauv hloov lub zog hluav taws xob kev co lub zog ua rau lub zog sib xyaw. Yog tias qhov sib chwv ntawm qhov tsim nyog welded yas ib feem ntxiv, vuam ntu Thaum cov pob qij txha ntawm qhov chaw sintered yog sib zog rubbed, cov cua sov tau tsim thiab cov molecules hloov fuse kom tau txais cov vuam nyhuv.
Cov txheej txheem vuam ultrasonic yog ceev, lub sijhawm vuam tsawg dua li 1 thib ob, thiab lub tshuab ua haujlwm tau yooj yim. Kev siv tshuab tsis siv neeg ultrasonic vuam los ntawm cov yas ntim khoom ua si tuaj yeem txhim kho kev ua hauj lwm ntau lawm thiab pab cov kev lag luam hloov thiab hloov kho dua tshiab.
