iav lub raj misntau lawm technology mas suav nrog: ① raw khoom ua ntej ua.Cov ntaub ntawv nyoos loj (quartz xuab zeb, dej qab zib tshauv, limestone, feldspar, thiab lwm yam) yog crushed, cov ntaub ntawv ntub dej qhuav, thiab cov khoom siv hlau uas muaj hlau raug kho nrog cov hlau tshem tawm kom ntseeg tau qhov zoo ntawm cov khoom siv raw.iav.② Kev npaj cov ntaub ntawv nyuaj.③ Melting.Cov iav compound yog rhuab ntawm qhov kub siab (1550 ~ 1600 degrees) hauv lub pas dej ua ke los yog lub pas dej ua kom sov, kom nws cov ntawv sib xws, tsis muaj npuas, thiab ua tau raws li qhov yuav tsum tau ua ntawm cov kua iav.④ Kev tsim kho.Muab cov iav ua kua rau hauv pwm kom ua cov khoom siv iav uas xav tau, xws li cov phaj, ntau yam khoom siv, thiab lwm yam. ⑤ Kev kho cua sov.Los ntawm annealing, quenching thiab lwm yam txheej txheem, tshem tawm lossis tsim kev ntxhov siab sab hauv, theem kev sib cais lossis crystallization, thiab hloov cov txheej txheem ntawm lub khob.Qhov zoo ntawmiav ntimcov thawv ntim hauv cov dej ntim dej.
Cov khoom ntim iavthiab cov thawv ntim khoom muaj ntau yam zoo:
1.iav khoommuaj kev tiv thaiv zoo, tuaj yeem tiv thaiv cov pa oxygen thiab lwm yam roj hauv kev ntxeem tau, tib lub sijhawm tuaj yeem tiv thaiv cov khoom tsis zoo ntawm sab hauv mus rau qhov chaw tsis muaj zog;
2. Cov iav fwj tuaj yeem siv tau ntau zaus, uas tuaj yeem txo cov nqi ntim khoom;
3.lub iav tuaj yeem hloov xim thiab pob tshab;
4. iav fwjkev nyab xeeb thiab kev noj qab haus huv, zoo corrosion kuj thiab acid corrosion kuj, haum rau acidic tshuaj (yog hais tias zaub kua txiv, thiab lwm yam) ntim;
5. Tsis tas li ntawd, vim hais tias lub iav lub raj mis tsim nyog rau kev tsim cov khoom siv tsis siv neeg filling ntau lawm kab, txoj kev loj hlob ntawm domestic iav fwj tsis siv neeg filling tshuab thiab cov cuab yeej yog tus paub tab, thiab kev siv.iav fwjlos ntim cov txiv hmab txiv ntoo thiab zaub kua txiv hmab txiv ntoo muaj qee yam khoom zoo hauv Suav teb.Thawj yog tsim thiab tsim cov pwm.Cov iav raw khoomyog quartz xuab zeb ua cov khoom siv tseem ceeb, thiab lwm yam khoom siv tau yaj hauv cov kua hauv qhov kub thiab txias, thiab tom qab ntawd txhaj rau hauv pwm, txias, txiav thiab tempering, los tsim ib lub raj mis iav.iav fwjfeem ntau muaj cov cim nruj, uas yog ua los ntawm cov pwm pwm.iav raj mis moldingRaws li txoj kev tsim khoom tuaj yeem muab faib ua tshuab tshuab, tshuab tshuab thiab extrusion molding peb hom.Cov iav fwj tuaj yeem muab faib ua hom hauv qab no raws li qhov muaj pes tsawg leeg: ib qho yog sodium iav, ob yog iav iav thiab peb yog iav borosilicate.
Cov ntaub ntawv tseem ceeb ntawm cov iav fwj yog ntuj ore, quartz pob zeb, caustic soda, limestone thiab lwm yam.Cov iav fwj muaj qhov siab ntawm qhov pom tseeb thiab kev tiv thaiv corrosion, thiab kev sib cuag nrog cov tshuaj feem ntau yuav tsis hloov cov khoom siv.Nws cov txheej txheem tsim khoom yog yooj yim, pub dawb thiab hloov tau cov duab, siab hardness, kub tsis kam, huv, yooj yim los ntxuav, thiab muaj cov yam ntxwv ntawm kev siv dua.Raws li cov khoom ntim, iav fwj feem ntau yog siv rau hauv cov khoom noj, roj, cawv, dej qab zib, condiments, tshuaj pleev ib ce thiab kua tshuaj, thiab lwm yam.Tab sis cov iav fwj kuj muaj nws qhov tsis zoo, xws li hnyav hnyav, kev thauj mus los thiab cov nqi khaws cia, kev cuam tshuam thiab lwm yam.
