Kev txiav txim siab lub sijhawm sintering zoo tom qab magnesium oxide refilling yuav tsum xav txog qhov ntsuas kub, cov khoom siv, thiab cov txiaj ntsig kev xeem. Nws feem ntau yog 1-2 teev. Lub sij hawm no yog txaus los xyuas kom meej txaus recrystallization ntawm magnesium oxide nplej, tsim ib tug ntom thiab ruaj khov insulating qauv.
1. Raws li qhov sib piv ntawm qhov kub thiab txias ntawm cov khoom siv
|
Hom khoom |
Pom zoo tuav lub sij hawm |
Kev piav qhia |
|
High-purity magnesium oxide (Ntau dua lossis sib npaug rau 99.9%) |
1-1.5 hnub |
Tsawg impurities, siab ua haujlwm, ceev recrystallization |
|
Nanoscale los yog ultrafine hmoov |
1 hnu |
Loj thaj chaw tshwj xeeb, yooj yim rau sinter, zam dhau - hlawv |
|
Pa hluav taws xob qib (100-200 mesh) |
1.5-2 hnub |
Yuav tsum tau tuav lub sij hawm ntev los xyuas kom meej qhov ntom thiab uniformity |
Hauv kev xyaum, tuav ntawm 900℃rau 1.5 teev yog cov txheej txheem rau feem ntau cov tuam txhab ua raws (xws li Liaoning Jiashun Technology).
2. Kev txheeb xyuas los ntawm qhov me me - batch gradient testing: Nws raug nquahu kom ua qhov kev sim firings ntawm peb lub sijhawm: 1 teev, 1.5 teev, thiab 2 teev, nrog 3 tus qauv rau ib pawg. Ntsuas cov ntsuas tseem ceeb hauv qab no:
Txias rwb thaiv tsev tsis kam (Ntau dua lossis sib npaug rau 500 MΩ)
Ua haujlwm voltage (AC 2000V, tsis tawg tom qab 1 feeb)
Kev ua haujlwm tom qab kub thiab av noo (Ntau dua lossis sib npaug rau 200 MΩ)
Kev txheeb xyuas qhov tshwm sim: Xaiv lub sijhawm taw tes nrog cov ntaub ntawv ruaj khov tshaj plaws thiab tsis muaj kev cuam tshuam flashover raws li qhov kev pom zoo kom tsis txhob ua haujlwm tsis zoo vim lub sijhawm tsis txaus.
3.Ua raws li cov qauv kev lag luam thiab kev coj ua: HG / T 6445-2025 qhia tias lub sijhawm tuav sintering yuav tsum tsis pub tsawg tshaj 1 teev, thiab cov ntaub ntawv ua tiav thermal tswj nkhaus yuav tsum tau muab.
Cov neeg muab kev pabcuam raws li kev pabcuam xws li Liaoning Jiashun Technology thiab Dashiqiao Meier Magnesium Khoom siv 1.5 teev raws li cov txheej txheem txheej txheem sijhawm.
Hauv siab - qhov yuav tsum tau muaj xws li kev txhaj tshuaj molding thiab daim ntawv thov kev kho mob, 1.5-2 teev yuav tsum tau ua qhov tseem ceeb kom ntseeg tau ntev -lub sij hawm.
Yog tias lub sijhawm tsawg dua 1 teev, nws yooj yim ua rau tsis tiav recrystallization thiab xoob rwb thaiv tsev qauv; yog tias nws ntev dhau lawm, nws yuav ua rau muaj kev siv zog ntau ntxiv thiab cov khoom muaj kev pheej hmoo ntawm kev laus.
