Cov txheej txheem tsim cov iav fwj feem ntau suav nrog cov kauj ruam hauv qab no:
Raw khoom ua ntej: Crush block zoo li raw cov ntaub ntawv (xws li quartz xuab zeb, soda tshauv, limestone, feldspar, thiab lwm yam) kom qhuav cov ntaub ntawv raw, thiab tshem tawm cov hlau los ntawm cov hlau uas muaj cov ntaub ntawv raw los xyuas kom meej iav zoo.
Kev npaj Batch: Sib tov cov khoom nyoos crushed nyob rau hauv kev faib ua feem los ua ib khob batch.
Melting: Thaum kub kub (1550-1600 degrees), ua kom sov lub batch nyob rau hauv ib lub tank los yog lub cub tawg los ua ib tug uniform, npuas tsis muaj kua iav.
Kev tsim: Muab cov iav ua kua rau hauv pwm thiab siv txoj hauv kev xws li kev tuav tshuab, tshuab tshuab, lossis extrusion los tsim cov khoom iav uas xav tau.
Kev kho cua sov: Los ntawm annealing, quenching thiab lwm yam txheej txheem, kev ntxhov siab, theem kev sib cais lossis crystallization hauv lub khob raug ntxuav los yog tsim, nrog rau cov txheej txheem ntawm lub khob hloov.
Annealing: Yuav kom tshem tawm cov thermal stress nyob rau hauv iav, nws yog ib qho tsim nyog yuav tau ua kev kho annealing ntawm cov khoom iav.
Tsis tas li ntawd, qee qhov chaw tsim khoom kuj tseem siv cov iav iav fwj ua raw khoom, uas yog crushed, tov, melted, thiab ces molded rau hauv iav fwj tshiab. Thoob plaws hauv tag nrho cov txheej txheem tsim khoom, cov kab sib txuas ua ke tuaj yeem tsim tau ntau pua lub khob iav ib feeb.
Thaum txhim kho qhov hnyav, ntau lawm thiab molding tus nqi, nrog rau tus kheej thiab yooj yim ntawm lub raj mis iav thiab cov khoom lag luam, cov khoom zoo ntawm lub raj mis iav thiab cov khoom tuaj yeem yog qhov tseem ceeb ntawm kev txhawj xeeb. Thaum txhim kho cov txheej txheem ntau lawm thiab molding tswj cov iav fwj thiab cov khoom lag luam, cov khoom lag luam zoo ntawm lub raj mis iav thiab cov khoom tuaj yeem yuav tsum yog qhov tseem ceeb ntawm kev txhawj xeeb. Tsis muaj teeb meem dab tsi hloov pauv rau cov txheej txheem molding, cov khoom lag luam zoo thiab kev ua haujlwm ntawm lub raj mis iav thiab cov khoom tuaj yeem yuav tsum tsis txhob hloov pauv, uas yog qhov tseem ceeb heev.
Los ntawm qhov kev xav ntawm kev tswj cov txheej txheem molding thiab cov khoom zoo ntawm lub raj mis iav thiab cov khoom lag luam, nws yog ib qho tseem ceeb rau cov iav kom sib npaug sib npaug thoob plaws hauv lub raj mis thiab tuaj yeem tsim khoom. Nyob rau hauv txoj kev no, iav fwj cov khoom tuaj yeem muaj phab ntsa tuab txaus los tiv thaiv kev ntxhov siab los ntawm cov khoom siv iav. Tau kawg, phab ntsa tuab ntawm iav lub raj mis thiab cov khoom lag luam tsis tas yuav tsum yog tuab heev, txwv tsis pub nws yuav ua rau cov khoom siv raw ntau dhau, kev siv zog thiab kev siv, cov khoom pov tseg ntau dhau, thiab lwm yam yuav tshwm sim, yog li nce tus nqi ntawm lub raj mis iav. thiab tuaj yeem ua cov khoom.
