Cov txheej txheem tseem ceeb rau kev kuaj xyuas yog tias sintering tiav tom qab magnesium oxide refilling yog los ntawm kev ntsuas kev ua tau zoo thiab kev ntsuas lub cev kom paub meej tias cov rwb thaiv tsev tsis kam, tiv taus qhov hluav taws xob, thiab microstructure ua tau raws li cov qauv. Cov kev sim tshwj xeeb yog raws li hauv qab no:
1. Kev Ntsuas Kev Ntsuas Qhov Tseem Ceeb
|
Cov khoom kuaj |
Txais Cov Qauv |
Kev piav qhia |
|
Txias rwb thaiv tsev Resistance |
Ntau tshaj lossis sib npaug rau 500 MΩ (500V DC) |
Ntsuas siv calibrated 2500V megohmmeter, tsis suav nrog kev cuam tshuam ntawm qhov dej. |
|
Txias Withstand Voltage Test |
AC 2000V, tsis tawg hauv 1 feeb |
Yuav tsum tau ua tom qab rwb thaiv tsev tiv thaiv yog tsim nyog los tiv thaiv cov khoom puas. |
|
Kub rwb thaiv tsev Resistance |
Ntau dua lossis sib npaug li 200 MΩ (hauv 2 vib nas this tom qab lub zog tsis ua haujlwm tom qab 30 feeb ntawm kev ua haujlwm) |
Txheeb xyuas cov qauv kev ruaj ntseg ntawm qhov kub thiab txias. |
|
Kev Ntsuas Hydraulic |
Ntau dua lossis sib npaug rau 200 MΩ tom qab 48 teev ntawm 40℃thiab 95% RH |
Simulates high humidity tej yam kev mob los ntsuam xyuas cov dej noo nqus tsis kam. |
Tag nrho cov ntaub ntawv xeem yuav tsum tau traceable thiab qhia los ntawm ib lub chaw kuaj uas tsim nyog.
2. Lub cev thiab microscopic yam ntxwv ntawm tiav Sintering
Cov nplej zoo Recrystallization: Metallographic tsom xam pom tias magnesium oxide nplej tau loj hlob zoo, ntim ntom ntom, thiab tsis muaj xoob lossis porosity;
Uniform Filling Density: Ntsuas qhov ceev yog nyob nruab nrab ntawm 2.8–3.2 g / cm³, thiab X- kev tshuaj ntsuam kab hluav taws xob tsis pom tawm - nruab nrab cores lossis voids;
Tsis muaj thermal Stress Cracks: Cov hlau casing qhia tsis muaj deformation los yog tawg, thiab lub qhov hluav taws xob terminals yog zoo- kaw;
Strong Sealing: Ceramic sealing adhesive lossis hlau sealing yog siv, ua tiav IP65 lossis siab dua kev tiv thaiv.
Yog tias muaj kev hloov pauv loj hauv rwb thaiv tsev tsis kam, flashover thaum lub sij hawm ntsuas qhov ntsuas hluav taws xob, lossis kev poob siab tam sim ntawd tom qab pom cov dej noo, nws qhia tias tsis tiav sintering.
3. Txheej txheem Traceability Verification
Yuav tsum muaj kev tswj xyuas qhov ntsuas kub kom tiav (kub- lub sijhawm teeb) yuav tsum tau muab, lees paub lub sijhawm tuav ntawm 800-1000℃rau 1-2 teev; Cov ntaub ntawv huab cua yuav tsum qhia txog kev siv siab -purity nitrogen (cov ntsiab lus oxygen<100ppm); The repair manufacturer should possess compliance qualifications according to HG/T 6445-2025 and JB/T 2379-2016.
Nyob rau hauv kev xyaum, tag nrho sintered cua sov cov ntsiab lus tuaj yeem ua haujlwm ruaj khov rau ntau tshaj 15,000 teev hauv kev thov xws li kev txhaj tshuaj molding thiab kev siv kho mob.
