Hauv kev tsim cov tsheb tsim kev lag luam, kev muab tso rau qhov tseeb ntawm lub vuam fixture' s kev qhia tus pin yog qhov tseem ceeb rau qhov loj ntawm lub cev sib dhos thiab vuam, thiab vuam qhia tus pin' s looseness thiab hnav ntau dhau yog ob qho tseem ceeb. ua rau nws tso qeb tsis ua haujlwm. Txhawm rau daws cov teeb meem no, UNIPRETEC tau kawm thiab tsim Ceramic Pin rau Projection Vuam. Vim tias lawv lub siab hardness, thermal poob siab lub zog, hluav taws xob insulating, thiab tsis kam mus rau cov neeg kho tshuab nkag ntawm qhov kub kom txias, ceramic vuam pins outperform lwm cov ntaub ntawv. Projection vuam tso cai rau kev ua kom pom tseeb ntxiv ntawm cov vuam vias thiab cov txiv ntoo ntau dua li cov khoom siv. Vim tias hluav taws xob insulating zog ntawm kev tshaj lij thev naus laus zis, tsis muaj kev sib tw rho tawm kev ua haujlwm yog qhov tsim nyog tom qab vuam, thiab xov tsis cuam tshuam, uas nce kev tsim khoom thiab zoo heev txhim kho vuam zoo. Ceramics muaj qhov qhia tau zoo ntawm kev nruj thiab qhov kub hnyav kom hnav. Cov kev pab cuam lub neej ntawm kev muab tso rau vuam pins ua los ntawm lwm cov ntaub ntawv yog ntau zaus ntawm kev muab tso rau vuam pins ua los ntawm lwm cov ntaub ntawv, zoo heev txo cov txheej txheem tsim khoom, ua kom muaj kev pab cuam lub neej, thiab txo tus nqi.

Qhov kev cuam tshuam tseem ceeb ntawm lwm cov ntaub ntawv raws li qhov projection vuam pins yog tias lub txiv ntseej welded yuav tsum rov tshawb dua tom qab vuam. Tsis tas li ntawd, vuam pins ntawm lwm cov ntaub ntawv muaj lub neej luv thiab xav tau hloov chaw ntau zaus, uas ua rau cov nqi zog ua haujlwm tsawg dua thiab txo qhov kev tsim khoom. Kev siv cov txuas ntawm weld pins tshem tawm qhov kev xav tau slag kev tshem tawm rau cov txiv ntoo tom qab welding, uas txo cov txheej txheem ntau, txhim kho kev ua haujlwm, thiab txhim kho vuam zoo. Tus nqi ntawm ceramic silicon nitride vuam pins yog 10-30 zaug ntawm lwm cov ntaub ntawv, tab sis kev pab cuam lub neej yog 15-20 npaug ntawm lwm cov ntaub ntawv. Txawm hais tias kev nqis peev ib zaug yuav loj, tab sis nyob rau hauv qhov kev sib piv tag nrho, vim kev ncua lub neej, cov txheej txheem txuas ntxiv tom qab raug rho tawm. Tus nqi zoo / piv ua tau zoo tau txais.

UNIPRETEC ua tau zoo ntawm kev ua cov weld pins ntawm cov khoom sib txawv ceramic raws li cov neeg siv khoom' s kos duab, suav nrog Alumina (Al2O3), Zirconia (ZrO2) thiab Silicon Nitride (Si3N4). Cov ntau lawm tuaj yeem ua tau yooj ywm nrog cov khoom me me, thiab lub sijhawm khoom xa tuaj yog luv heev.
