Lub hauv paus ntawm kev tiv thaiv tshaj cov qauv hauv kub- lub xeev kev sim yog nyob rau hauv nruj tswj cov txheej txheem sintering, kom ntseeg tau tias airtightness, thiab standardizing cov txheej txheem kuaj. Feem ntau ntawm cov teeb meem tshaj li cov qauv (xws li kub- xeev rwb thaiv tsev tsis kam<200 MΩ) stem from defects in the early stages of the 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 Control and Holding: Lub sintering kub yuav tsum ruaj khov ntawm 800-1000 degree, nrog 900℃± 50℃pom zoo. Lub sij hawm tuav yuav tsum tsis pub tsawg tshaj 1 teev, nyiam dua 1.5 teev, kom paub meej tias cov nplej kom txaus recrystallization.
Segmented Cua sov thiab PID Control: Cov cua kub yuav tsum tswj 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 ua tiav thermal tswj nkhaus.
Kev tiv thaiv huab cua txaus: Siv siab -purity nitrogen (Ntau dua lossis sib npaug li 99.99%) lossis ib puag ncig lub tshuab nqus tsev nrog cov ntsiab lus oxygen<100ppm to prevent high-temperature oxidation and carbonization. Sintering processes conforming to the HG/T 6445-2025 standard can increase the hot-state insulation resistance pass rate to over 98%.
2. Txhim kho sealing thiab noo noo-Kev ntsuas pov thawj
High-Kev ntseeg tau ntawm Sealing Structure: Ua ntej siv cov khoom sib xyaw ua ke uas muaj cov nplaum 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: Kev ua haujlwm sealing tau ua tiav hauv chav huv huv tsawg dua lossis sib npaug li 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 ntawm kev sib khi: Txhua yam khoom yuav tsum tau kuaj 0.3MPa airtightness rau 30 feeb thiab X-ray tshuaj xyuas kom tshem tawm qhov tsis xws luag xws li micropores thiab misalignments.
Kev sib khi tsis zoo yog qhov ua rau "txias-lub xeev dhau, kub- xeev tsis ua hauj lwm" thiab yuav tsum yog qhov tseem ceeb ntawm kev tiv thaiv thiab tswj.

Kub Lub Xeev Ntsuas Sijhawm |
Ua kom tiav kev ntsuas kev tiv thaiv tsis pub dhau 2 vib nas this tom qab lub zog tsis ua haujlwm |
Ua kom cov ntaub ntawv raug cuam tshuam txog qhov siab -kub lub xeev thiab 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 cuam tshuam rau qhov kev nyeem ntawv |
Txhim kho qhov ntsuas qhov tseeb thiab sib xws. Nws raug nquahu kom nruab ib lub ntsuas hluav taws xob nrog kev ua haujlwm tsis siv neeg kom txo qis kev txiav txim siab los ntawm tib neeg ncua sijhawm. |
