Xyuas kom lub sealing tom qab magnesium oxide refilling hinges ntawm kev siv cov txheej txheem sealing txhim khu kev qha, tswj kev huv ntawm ib puag ncig, thiab ua tiav qhov kev tiv thaiv IP65 lossis siab dua. Cov kev siv tshwj xeeb yog raws li hauv qab no:
1. Xaiv lub siab -Txoj kev muaj kev ruaj ntseg sealing
|
Txoj Kev Sealing |
Siv tau Scenarios |
Cov Lus Qhia Tseem Ceeb |
|
Ceramic Sealing Adhesive |
Siab-kub, siab- cov av noo (xws li, kho mob, txhaj tshuaj molding) |
Siv ceramic-raws li nplaum nplaum nrog qhov kub thiab txias ntawm ntau dua lossis sib npaug li 600 degree, tsim cov txheej txheej ntom ntom tom qab kho. |
|
Hlau Sealing (piv txwv li, brazing) |
Ib puag ncig hnyav lossis ntev - cov khoom siv ua haujlwm ntev |
Siv argon arc vuam lossis induction vuam kom ntseeg tau tias cov vuam tsis muaj qhov hws thiab tawg. |
|
Composite Sealing Structure |
Cov xwm txheej nrog kev ntseeg siab siab |
Muab ob npaug rau kev tiv thaiv nrog ceramic nplaum thiab lub nplhaib hlau sealing, txhim kho lub sijhawm ntev -. |
Tom qab kev sib khi, qhov ntsuas IP65 lossis siab dua kev tiv thaiv yuav tsum ua kom tiav los tiv thaiv plua plav thiab ya raws.
2. Kev tswj hwm nruj ntawm kev ua haujlwm ib puag ncig
Chav Kawm Cleanroom: Kev ua haujlwm sealing yog ua nyob rau hauv chav huv huv tsawg dua lossis sib npaug li 100,000 chav kawm kom tsis txhob muaj plua plav paug ua rau muaj qhov tsis xws luag;
Humidity Control: Tus txheeb ze av noo tsawg dua los yog sib npaug li 30% los tiv thaiv magnesium oxide hmoov los ntawm absorbing noo noo ua ntej sealing;
Inert Atmosphere Protection: Siab -purity nitrogen (cov ntsiab lus oxygen<100ppm) is introduced during the sealing process to prevent high-temperature oxidation.
Rau txhua txhua 10% nce av noo, lub sealant txoj kev kho lub zog txo los ntawm kwv yees li 8%, cuam tshuam rau lub sij hawm ntev -.
3. Kev soj ntsuam xyuas thiab kev kuaj xyuas zoo sealing
Kev soj ntsuam pom: Cov nplaum nplaum yog tsis muaj npuas, tawg, thiab cov kab noj hniav shrinkage; hlau welds yog ib yam thiab tas mus li;
Cua Tightness Test: Cov khoom tiav yog raug rau 0.3MPa siab thiab tuav rau 30 feeb yam tsis muaj to;
Kev Ntsuas Kev Ntsuas Dej: Tom qab muab tso rau hauv ib puag ncig ntawm 40℃thiab 95% RH rau 48 teev, qhov rwb thaiv tsev tsis kam yog ntau dua lossis sib npaug li 200 MΩ;
X-Ray Inspection: Tshawb xyuas thaj chaw sealing rau micropores, misalignment, lossis tsis txaus filling.
Hauv kev xyaum, X-rays tuaj yeem ntes micron- theem qhov khoob qhov tsis pom ntawm qhov muag liab qab, ua rau nws yog ib qho yuav tsum tau soj ntsuam rau cov ntawv thov siab - kawg.
4. Xaiv Cov Kev Pabcuam Ua Raws Cai thiab Cov Khoom Siv Txheej Txheem Ua ntej muab kev pabcuam kev sib khi rau cov chaw uas koom nrog kev tsim qauv ntawm HG/T 6445-2025 tus qauv, xws li:
Liaoning Jiahun Technology; Dashiqiao Meier Magnesium khoom; Shanghai Shiye Zhentai Tshuaj. Thawj cov chaw tsim khoom-cov ntaub ntawv pov thawj sealing yuav tsum tau siv, thiab cov ntaub ntawv pov thawj ntawm cov txheej txheem sealing thiab cov ntaub ntawv xeem yuav tsum tau txais los xyuas kom meej qhov kev taug qab.
