Thaum tshav kub kub so rau tempered iav yog txheej txheem siv los txo qhov kev pheej hmoo ntawm kev tawg ntawm cov iav.
Tempered iav yog paub txog nws lub zog thiab kev nyab xeeb nta, tab sis nws tseem tuaj yeem raug cuam tshuam los ntawm kev tawg vim yog nickel sulfide inclusions. Cov kev suav nrog no yog cov khoom me me uas tuaj yeem ua rau lub khob tawg hauv qee yam mob. Thaum tshav kub kub yog muab cov iav tempered rau hauv qhov cub tshwj xeeb thiab ua kom sov rau qhov kub thiab txias rau lub sijhawm teem sijhawm. Cov txheej txheem no yog tsim los yuam cov iav panels nrog cov nickel sulfide inclusions kom tawg thaum lub caij sov so, tsis yog tom qab kev teeb tsa. Los ntawm kev txheeb xyuas thiab tshem tawm cov faulty panels ua ntej lawv raug teeb tsa, cov cua sov so yuav pab txo qis qhov kev pheej hmoo ntawm kev tawg ntawm cov iav tempered. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tsim vaj tsev thiab cov qauv tsim uas qhov tshwm sim ntawm cov iav tawg tuaj yeem loj heev.
Thaum tshav kub kub soaking yog ib qho tseem ceeb zoo tswj cov kauj ruam nyob rau hauv zus tau tej cov tempered iav, pab kom muaj kev ruaj ntseg thiab kev cia siab ntawm cov khoom kawg. Thaum tshav kub kub soaking rau tempered iav yog ib tug txheej txheem siv los txo cov kev pheej hmoo ntawm spontaneous breakage nyob rau hauv lub khob. Tempered iav yog paub txog nws lub zog thiab kev nyab xeeb nta, tab sis nws tseem tuaj yeem raug cuam tshuam los ntawm kev tawg vim yog nickel sulfide inclusions. Cov kev suav nrog no yog cov khoom me me uas tuaj yeem ua rau lub khob tawg hauv qee yam mob. Thaum tshav kub kub yog muab cov iav tempered rau hauv qhov cub tshwj xeeb thiab ua kom sov rau qhov kub thiab txias rau lub sijhawm teem sijhawm. Cov txheej txheem no yog tsim los yuam cov iav panels nrog cov nickel sulfide inclusions kom tawg thaum lub caij sov so, tsis yog tom qab kev teeb tsa.
Los ntawm kev txheeb xyuas thiab tshem tawm cov faulty panels ua ntej lawv raug teeb tsa, cov cua sov so yuav pab txo qis qhov kev pheej hmoo ntawm kev tawg ntawm cov iav tempered. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tsim vaj tsev thiab cov qauv tsim uas qhov tshwm sim ntawm cov iav tawg tuaj yeem loj heev. Thaum tshav kub kub yog ib qho tseem ceeb ntawm kev tswj cov txheej txheem ntawm kev tsim cov iav tempered, pab kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom kawg.
Tus kheej tawg yuav tsawg dua 0.3%.
Ib hom kev tsis zoo yog nickel sulfide (NiS) suav nrog. Feem ntau NiS suav nrog ruaj khov thiab tsis ua rau muaj teeb meem. Muaj, txawm li cas los xij, lub peev xwm rau NiS suav nrog uas tuaj yeem ua rau muaj kev tawg ntawm cov iav tempered yam tsis muaj kev thauj khoom lossis kev ntxhov siab thermal.
Thaum tshav kub kub yog txheej txheem uas yuav nthuav tawm NiS suav nrog hauv cov iav tempered. Cov txheej txheem suav nrog muab cov iav tempered rau hauv lub chamber thiab nce qhov kub kom txog li 550 degree F lossis 287 degree kom nrawm NiS nthuav dav. Qhov no ua rau cov iav uas muaj NiS suav nrog ua kom tawg hauv cov cua sov so hauv chav, yog li txo qhov kev pheej hmoo ntawm qhov chaw tawg.
