Lub raj mis iav muaj qhov zoo ntawm cov txheej txheem tsim khoom yooj yim, dawb thiab hloov tau zoo, siab hardness, kub tsis kam, huv si, yooj yim tu, thiab tuaj yeem siv ntau zaus.Ua ntej tshaj plaws, nws yog ib qho tsim nyog los tsim thiab tsim cov pwm.Cov khoom siv raw ntawm lub raj mis yog quartz xuab zeb ua cov khoom siv tseem ceeb, thiab lwm yam khoom siv tau yaj mus rau hauv cov kua hauv lub xeev ntawm qhov kub thiab txias, thiab tom qab ntawd lub raj mis roj tseem ceeb yog txhaj rau hauv pwm, txias, txiav, thiab tempered rau daim ntawv. ib lub raj mis.Cov iav fwj feem ntau muaj cov cim nruj, uas kuj yog tsim los ntawm cov duab puab.Lub molding ntawm iav fwj tuaj yeem muab faib ua peb hom: phau ntawv tshuab tshuab, tshuab tshuab thiab extrusion molding raws li txoj kev tsim khoom.
① Raw khoom ua ntej.Lub raj mis iav yog lub thawv ntim khoom haus ib txwm nyob hauv kuv lub tebchaws, thiab iav kuj yog cov khoom ntim keeb kwm heev.Nrog ntau hom ntim cov ntaub ntawv dej nyab mus rau hauv kev ua lag luam, cov thawv iav tseem tuav txoj haujlwm tseem ceeb hauv kev ntim dej haus, uas yog qhov sib cais ntawm nws cov ntim ntim uas tsis tuaj yeem hloov los ntawm lwm cov khoom ntim.Cov ntaub ntawv nyoos (quartz xuab zeb (cov khoom siv: silicate minerals), dej qab zib tshauv, limestone, feldspar, thiab lwm yam) yog pulverized, cov ntaub ntawv ntub dej qhuav, thiab cov khoom siv hlau uas muaj hlau yog raug tshem tawm kev kho mob los xyuas kom meej cov ntaub ntawv raw. zoo ntawm iav.
② Kev npaj cov khoom xyaw.
③ Melting.Cov iav batch yog rhuab ntawm qhov kub siab (1550 ~ 1600 degrees) nyob rau hauv lub pas dej ua ke kiln los yog pas dej ua ke rauv los ua ib tug uniform, npuas-dawb kua iav uas ua tau raws li qhov yuav tsum tau molding.
④ Pwm.Muab cov iav ua kua rau hauv pwm los ua cov khoom iav ntawm qhov xav tau, xws li cov phaj tiaj tus, ntau yam khoom siv, thiab lwm yam.
⑤ Kev kho cua sov.Los ntawm annealing, quenching) thiab lwm yam txheej txheem, qhov kev ntxhov siab, theem kev sib cais lossis crystallization hauv lub khob raug tshem tawm lossis tsim tawm, thiab cov txheej txheem ntawm lub khob hloov.
