Kev ntsuas kev ua tau zoo tsuas yog ua tau tom qab magnesium oxide refilling tau ua tiav thiab sintered, thiab tom qab ntawd txias tag rau hauv chav sov. Tag nrho cov txheej txheem feem ntau siv sijhawm 3-5 teev. Lub sij hawm pes tsawg nyob ntawm qhov nruj ua raws li cov txheej txheem sintering thiab txias.
Cov kauj ruam tseem ceeb thiab ncua sij hawm ua ntej kev ntsuas kev ua tau zoo
Theem sij hawm piav qhia
Sintering Tuav 1-2 teev Grain recrystallization ua tiav nyob rau hauv ib qho chaw inert ntawm 800-1000 degree
Ntuj Txias nyob rau hauv cub tawg 1-2 teev Txias los ntawm qhov kub thiab txias mus rau<200℃ to prevent thermal stress cracking
Ua kom txias rau chav kub tom qab tshem tawm ntawm lub cub tawg Kwv yees li 30-60 feeb Ua kom cov khoom ntsuas kub nyob ib puag ncig 25℃kom tsis txhob muaj qhov yuam kev
Kev ntsuam xyuas tuaj yeem pib ntxov li 3 teev tom qab pib sintering, tab sis nws yuav tsum tau lees paub tias cov khoom tau txias tag thiab ib puag ncig qhuav (RH Tsawg dua lossis sib npaug li 30%).
Pom zoo cov khoom xeem thiab ib ntus
Txias rwb thaiv tsev Resistance Test (500V DC)
Txuj: Ntau dua lossis sib npaug ntawm 500 MΩ Siv lub ntsuas ntsuas 2500V megohmmeter txhawm rau tshem tawm qhov cuam tshuam los ntawm qhov chaw.
Txias Withstand Voltage Test
Txheem: AC 2000V, tsis muaj kev tawg lossis flashover hauv 1 feeb. Yuav tsum tau ua tom qab lub rwb thaiv tsev tiv thaiv tsim nyog los tiv thaiv cov khoom puas.
Kev ntsuas kub thiab av noo (Kev Ntsuas Tom Qab)
Kub: Ntsuas rwb thaiv tsev nyob rau hauv 2 vib nas this ntawm lub hwj chim tsis ua hauj lwm tom qab 30 feeb ntawm kev ua hauj lwm; Ntau dua lossis sib npaug li 200 MΩ.
Humid: Rov ntsuas dua tom qab 48 teev ntawm 40℃thiab 95% RH; Ntau dua lossis sib npaug li 200 MΩ. Kev ntsuam xyuas yam tsis muaj qhov txias txaus yuav ua rau cov ntaub ntawv cuam tshuam lossis kev txhais cov cuab yeej tsis raug, ua rau muaj kev phom sij.
