Txoj Kev Vuam Thiab Daim Ntawv Thov Cov Khoom Ua Si Yas
Muaj kev thov ntau rau cov khoom ua si yas ua khoom lag luam hauv khw. Dab tsi yog cov kev vuam sib txuas?
Thaum nws tawm los rau yas, txhua tus neeg paub txog nws. Los ntawm cov menyuam yaus cov khoom ua si rau cov thawv ntim khoom, los ntawm cov koos pij tawj rau cov khoom siv hauv tsheb, los ntawm txhuam cov tog raj kheej rau cov khoom dav hlau, cov khoom yas yog qhov txhia chaw hauv peb lub neej.
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 thermoset plastics, thiab tus nqi ntawm cov khoom lag luam yas tsim tawm tsis zoo ib yam li lwm txoj kev molding. Raws li ib qho ntawm cov cuab yeej tseem ceeb rau kev txhaj tshuaj molding, kev txhaj tshuaj pwm muaj qib qis hauv qhov ua tau zoo, lub voj voog tsim khoom thiab kev tsim khoom hauv cov txheej txheem txhaj tshuaj molding txheej txheem. Nws ncaj qha cuam tshuam cov khoom lag luam zoo, tsim tawm, tus nqi thiab cov khoom hloov tshiab, thiab tseem txiav txim siab rau lub tuam txhab. Kev lees paub thiab ceev hauv kev sib tw ua lag luam.
Hauv cov txheej txheem ntau lawm, plastics uas tawm los ntawm sib txawv txhaj tshuaj pwm feem ntau welded. Yog li, dab tsi yog cov hau kev ntawm vuam yas khoom ua si?
1. Kub phaj kub vuam
Yas qho khoom ua si kub phaj vuam tshuab nta: yooj yim, haum rau vuam chaw loj ntawm cov yas. Lub phaj hluav taws xob cua sov yog siv los txhawm rau ua kom kub sai rau ob sab ntawm vuam. Tom qab lub phaj hluav taws xob cua sov raug tshem tawm, cov plastics hauv ob sab yog fused los ntawm kev kub siab, thiab lub vuam ua tiav los ntawm txias. Kev tsis zoo: Lub voj voog ntev, thiab cov yas yog yooj yim los lo rau lub phaj kub, uas nyuaj rau ntxuav thiab ua paug.
2. Cov cua kub vuam
Nta: Sib dua, tab sis nyuaj rau kev khiav lag luam. Cov huab cua kub melts cov khoom tib yam ntawm lub weld thiab ua tiav vuam.
3. Mem tes vuam
Nias ob nplooj ntawm zaj duab xis thiab siv hlau nichrome kom tiav qhov soldering tam sim ntawd .
4. Txhuam Txhuam Vuam
Kev sib txhuam kub tsim los ntawm ob ntu nyob rau hauv kev ua haujlwm siab thaum lub sijhawm tag nrho cov txheej txheem ntawm kev txhuam ua rau ntawm cov yas yaj thiab muag muag, thiab kev sib cais yog tsau kom txog thaum lub solidification ruaj.
5. Ultrasonic vuam
Cov khoom siv cav tov ua si ultrasonic siv ntau lub tshuab ua lub zog ua kom mos muag lossis yaj cov thermoplastic ntawm qhov sib koom ua ke.
Cov ntu sib txuas yog tsau los ntawm lub siab, thiab qhov zaus feem ntau yog kis los ntawm ultrasonic kev co ntawm 20 ~ 40 kHz. Tus transducer hloov lub siab-zog kev co lub teeb liab mus rau lub zog yam xws li tshuab. Yog tias qhov tsim nyog vuam yas ntu ntxiv rau qhov sib tiv tauj, vuam ntu Qhov sib koom ua ke yog sib zog rub lub sijhawm thaum muaj kev sib txhuam, thiab cov lwg me me tau hloov pauv kom tau txais vuam nyhuv.
Cov txheej txheem ultrasonic vuam yog qhov nrawm, vuam lub sijhawm tsawg dua 1 vib nas this, thiab kev siv tshuab yooj yim. Cov yas ua si yas ua lag luam siv cov tshuab tsis siv neeg ultrasonic vuam txhawm rau txhim kho kev tsim khoom thiab pab cov chaw lag luam kom hloov pauv thiab nce ntxiv.
