Feem ntau ua rau sintering tsis ua hauj lwm tom qab magnesium oxide refilling muaj xws li kev tswj qhov kub thiab txias, lub sij hawm tuav tsis txaus, tsis muaj kev tiv thaiv huab cua, tsis sib xws, thiab txias txias heev. Cov yam ntxwv no tuaj yeem ua rau muaj qhov tsis xws luag hauv cov txheej txheem rwb thaiv tsev, ua rau kev ua haujlwm tsis zoo lossis kev puas tsuaj thaum lub sijhawm ua haujlwm.
1. Cov txheej txheem tsis tswj xyuas
|
Ua rau |
Kev cuam tshuam |
Kev Tiv Thaiv Kev Tiv Thaiv |
|
Tsawg dhau (<800℃) or too high (>1050 degree) |
Tsis muaj peev xwm ua kom tiav recrystallization lossis ua rau magnesium oxide volatilization thiab plhaub deformation. |
Siv cov thermocouples calibrated los xyuas kom meej qhov kub thiab txias qhov tseeb ± 10 degree. |
|
Tuav lub sijhawm<1 hour |
Kev loj hlob tsis txaus ntawm cov qoob loo, cov qauv xoob, thiab cov rwb thaiv tsev tsis muaj zog. |
nruj me ntsis tuav lub sij hawm tuav ntawm 1-2 teev. |
|
Kev kub ceev heev / cua txias |
Ua rau thermal stress tawg thiab puas lub foob. Cov cua kub tsawg dua lossis sib npaug li 5℃/ min; siv cov cua txias nrog lub qhov cub. |
Nyob rau hauv kev xyaum, 30% ntawm sintering tsis ua hauj lwm yog vim ib tug uncalibrated kub tswj system los yog tsis raug cov kev pab cuam chaw. |
2. Ib puag ncig tsis zoo
Tsis siv cov roj inert (xws li, nitrogen) tiv thaiv: Magnesium oxide tau nkag siab nrog cov pa oxygen thiab noo noo hauv huab cua ntawm qhov kub thiab txias, tsim impurities;
Cov ntsiab lus siab noo noo nyob rau hauv lub cub tawg (RH> 30%): Ua rau cov dej noo theem ob, ua rau tsis ua tiav ntawm kev ntsuas dej noo;
Tsis txaus lossis tsis sib npaug ntawm cov pa roj: Localized oxidation lossis carbonization.
Yuav tsum tau nqa tawm hauv lub tshuab nqus tsev lossis siab -purity nitrogen ib puag ncig, nrog cov ntsiab lus oxygen tswj <100 ppm.
3. Cov txheej txheem ua kom tiav thiab sib dhos
Tsis txaus purity ntawm magnesium oxide hmoov (< 99.9%): Impurities form conductive paths, leading to breakdown voltage;
Uneven filling ceev (< 2.8 g/cm³ or > 3.2 g/cm³): Too low a density leads to loosening, while too high a density causes stress concentration;
Tsis ua haujlwm siab - zaus vibration compaction: Internal voids muaj, ua rau overheating hauv zos thaum ua haujlwm.
X-Kev tshuaj xyuas kab hluav taws xob tuaj yeem kuaj pom qhov tsis xws luag xws li tawm ntawm- nruab nrab cores thiab voids.
4. Cov khoom siv thiab ib puag ncig tsis ua raws li cov qauv
Cleanroom Failure to Meet Standards (>100,000 chav kawm): Cov plua plav paug ua rau cov ntsiab lus tsis muaj zog hauv kev rwb thaiv tsev;
Tsis txaus Hydraulic Clamping Force: Tsis txaus axial siab ua rau xoob txhaws;
Pwm Hnav lossis Misalignment: Ua rau cov yeeb nkab deformation lossis foob misalignment.
Tsis yog-cov kev cob qhia kws tshaj lij feem ntau ntsib kev kho cov khoom ua tsis tiav vim cov khoom siv rudimentary.
5. Cov teeb meem ntawm cov khoom thiab sealing
Siv Industrial-Qib lossis Recycled Magnesium Oxide Powder: Ntau dhau impurities xws li Cl⁻ thiab SO₄²⁻ ua rau electrochemical corrosion;
Kev xaiv tsis raug Sealing Adhesive los yog tsis tiav Curing: Moisture seeps nyob rau hauv raws li cov leads, uas ua rau tsis ua hauj lwm los ntawm kev ntsuas noo noo;
Tsis Muaj Kev Tiv Thaiv -Oxidation Kev Kho Mob ntawm Cov Hluav Taws Xob Hluav Taws Xob: Ua kom muaj kev tiv thaiv kev tiv thaiv thiab ua kom muaj cua sov ntau dua tom qab ua haujlwm ntev -.
Hluav taws xob- qib siab- purity magnesium oxide yuav tsum tau siv ua ke nrog ceramic sealing nplaum los yog hlau sealant.
