Tus yuam sij rau kev tiv thaiv tshaj cov qauv hauv kev ntsuas kub yog nyob rau hauv nruj tswj cov txheej txheem sintering, kom ntseeg tau tias airtightness, thiab standardizing cov txheej txheem kuaj. Feem ntau tshaj cov qauv (xws li kub rwb thaiv tsev tsis kam<200 MΩ) stem from defects in the initial process and can be effectively avoided through the following measures:
1. Ua kom cov txheej txheem Sintering ua tau raws li cov qauv
Precise Temperature and Time Control: Khaws lub sintering kub ntawm 800-1000 degree, nrog lub sij hawm tuav tsis pub tsawg tshaj 1 teev, pom zoo kom 1.5 teev, kom txaus recrystallization ntawm cov nplej;
Segmented Temperature Control and PID Regulation: Cua sov npaum li cas tsawg dua los yog sib npaug li 5℃/ min kom tsis txhob thermal shock; siv lub tshuab hluav taws xob ntse sintering nrog cov ntaub ntawv kaw lus tsis siv neeg los xyuas kom meej qhov ua tiav thiab traceable thermal tswj nkhaus;
Kev tiv thaiv huab cua txaus: Siv siab - purity nitrogen (Ntau dua lossis sib npaug li 99.99%) lossis qhov chaw nqus tsev nrog cov ntsiab lus oxygen<100ppm to prevent high-temperature oxidation and carbonization.
Kev xyaum tau pom tias cov txheej txheem sintering ua raws li HG/T 6445-2025 tus qauv tuaj yeem ua rau kom kub-xeev rwb thaiv tsev tsis kam dhau mus rau ntau dua 98%.
2. Txhim kho sealing thiab noo noo-Cov pov thawj ntsuas
Txais Kev Siv Siab-Kev Ntseeg Sealing Technology: Ua ntej siv cov qauv sib xyaw ntawm cov nplaum nplaum nplaum thiab cov hlau sib khi kom ntseeg tau tias muaj kev tiv thaiv qib IP65 lossis siab dua;
Kev Tswj Ib puag ncig: Ua kom tiav kev sib khi hauv chav huv huv tsawg dua lossis sib npaug ntawm 100,000 chav kawm nrog cov av noo tas li ntawm RH Tsawg dua lossis sib npaug li 30% txhawm rau tiv thaiv cov plua plav thiab noo noo;
Yuav tsum tau muab pov thawj pov thawj: Txhua yam khoom yuav tsum xeem dhau 0.3MPa airtightness test rau 30 feeb thiab X-ray tshuaj xyuas kom tshem tawm qhov tsis xws luag xws li micropores thiab misalignment.
Kev sib khi tsis zoo yog qhov tseem ceeb ntawm "lub xeev txias dhau, ua tsis tiav lub xeev kub" thiab yuav tsum yog qhov tseem ceeb ntawm kev tiv thaiv thiab tswj.
3. Txuj kev ua haujlwm thiab cov xwm txheej zoo

Cold State Test Ua ntej |
Rwb thaiv tsev tsis kam Ntau dua lossis sib npaug ntawm 500 MΩ, tiv taus qhov hluav taws xob AC 2000V yam tsis muaj kev puas tsuaj |
Tshem tawm qhov muaj feem cuam tshuam hluav taws xob hauv lub hauv paus, tiv thaiv lub zog- nrog rau qhov tsis xws luag. |
|
Fais fab - ntawm Preheating Start |
Siv 50% lub zog rau 10-15 feeb, tom qab ntawd nce mus rau tag nrho cov load |
Exposes latent defects, tsis txhob cia li tsis ua hauj lwm nyob rau hauv tag nrho cov load. |
|
Kub Lub Xeev Ntsuas Sijhawm |
Ua kom tiav kev ntsuas kev tiv thaiv tsis pub dhau 2 vib nas this tom qab fais fab tuag |
Ua kom cov ntaub ntawv raug cuam tshuam txog qhov kub siab -, tsis txhob cuam tshuam los ntawm qhov kub thiab txias. |
|
Ib puag ncig kev sim qhuav |
RH Tsawg dua lossis sib npaug li 30% |
Tsis txhob ntog nto cuam tshuam rau kev nyeem ntawv Txhim kho qhov ntsuas qhov tseeb thiab sib xws |
Pom zoo kom nruab nrog lub rwb thaiv tsev tester nrog tsis siv neeg triggering muaj nuj nqi kom txo cov kev txiav txim tsis ncaj los ntawm tib neeg ncua.
4. Xaiv cov chaw muab kev pabcuam thiab cov ntaub ntawv txheem. Ua ntej tso siab rau kev kho thiab kev sim rau cov chav uas koom nrog hauv kev tsim ntawm HG / T 6445-2025 tus qauv, xws li:
Liaoning Jiahun Technology; Dashiqiao Meier Magnesium khoom; Shanghai Industrial Zhentai Tshuaj. Hluav taws xob qib siab -purity magnesium oxide hmoov (Ntau dua lossis sib npaug li 99.9%) thiab cov chaw tsim khoom qub -cov ntaub ntawv pov thawj yuav tsum tau siv, thiab ua tiav cov txheej txheem cov ntaub ntawv thiab cov ntawv xeem yuav tsum tau txais.
