Lub hauv paus tseem ceeb rau kev txiav txim siab seb puas sintering tom qab magnesium oxide refilling ua tiav yog los xyuas kom meej tias qhov ntsuas kub thiab kub rwb thaiv tsev tiv thaiv, tiv taus qhov ntsuas hluav taws xob, thiab ntsuas dej noo txhua qhov ua tau raws li cov qauv ntawm HG / T 6445-2025. Cov hauv qab no yog cov kev txiav txim tshwj xeeb:
1. Kev Ntsuas Kev Ua Tau Zoo Ua Raws Cai
|
Cov khoom kuaj |
Txais Cov Qauv |
Kev txiav txim tseem ceeb |
|
Txias rwb thaiv tsev Resistance |
Ntau tshaj lossis sib npaug rau 500 MΩ (500V DC, 25 degree) |
Txheeb xyuas qhov zoo ntawm rwb thaiv tsev zoo thiab tshem tawm luv luv -circuit risk |
|
Txias Withstand Voltage Test |
AC 2000V, 1 feeb, tsis tawg, tsis muaj flashover |
Txheeb xyuas cov txheej txheej rwb thaiv tsev ntom ntom thiab siab -voltage withstand peev |
|
Kub rwb thaiv tsev Resistance |
Ntau tshaj los yog sib npaug rau 200 MΩ (Tsib nyob rau hauv 2 vib nas this ntawm lub hwj chim disconnection tom qab 30 feeb ntawm ntsuas fais fab tuag) |
Paub meej tias cov rwb thaiv tsev ruaj khov ntawm qhov kub thiab txias |
|
Kev Ntsuas Hydraulic |
Rwb thaiv tsev tsis kam Ntau dua lossis sib npaug rau 200 MΩ tom qab 48 teev ntawm kev tso kawm hauv 40 degree, RH 95% ib puag ncig |
Simulates high humidity tej yam kev mob thiab xyuas kom meej noo noo absorption kuj |
Txhua qhov kev ntsuam xyuas yuav tsum siv lub ntsuas ntsuas 2500V megohmmeter thiab tiv taus qhov ntsuas hluav taws xob, thiab cov ntaub ntawv yuav tsum tau taug qab.
2. Cov yam ntxwv ntawm lub cev thiab thev naus laus zis ntawm Sintering zoo
Zoo Grain Recrystallization: Metallographic tsom xam pom tau tias muaj magnesium oxide nplej loj hlob nrog cov qauv ntom ntom, tsis muaj xoob lossis porosity;
Uniform Filling Density: Ntsuas qhov ceev yog nyob nruab nrab ntawm 2.8–3.2 g / cm³, thiab X-ray soj ntsuam pom tsis tawm-core lossis voids;
Tsis muaj thermal Stress Cracks: Cov hlau casing qhia tias tsis muaj deformation los yog tawg, thiab lub qhov hluav taws xob terminals yog zoo- kaw tsis muaj cov cim ntawm to;
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 kev tiv thaiv kev tiv thaiv hluav taws xob, flashover thaum lub sij hawm tiv thaiv qhov ntsuas hluav taws xob, lossis kev poob qis hauv kev tiv thaiv tom qab pom cov dej noo, nws qhia tias tsis txaus sintering lossis tsis sib xws.
3. Ua raws li cov qauv kev lag luam thiab cov ntaub ntawv pov thawj
Cov ntaub ntawv tshuaj xyuas lub Hoobkas thiab cov ntaub ntawv pov thawj kev txheeb xyuas cov khoom muaj pes tsawg leeg yuav tsum muab; Cov neeg muab khoom kho kho yuav tsum muaj cov kev tsim nyog ua raws li JB/T 2379-2016 thiab HG/T 6445-2025;
Nws raug nquahu kom muab cov kev pabcuam tseem ceeb los ntawm cov qauv tsim qauv xws li Liaoning Jiashun Technology, Dashiqiao Meier Magnesium Khoom, thiab Shanghai Industrial Zhentai Chemical.
Hauv kev xyaum, ua tiav cov khoom cua kub sintered tuaj yeem ua haujlwm ruaj khov rau ntau tshaj 15,000 teev nyob rau hauv siab - qhov yuav tsum tau muaj xws li kev txhaj tshuaj molding thiab daim ntawv thov kev kho mob.
