iav fwj thiab rhawv zeb muaj qee yam kev ua tau zoo thiab ua tau raws li cov qauv zoo

Cov ntaub ntawv raw thiab tshuaj muaj pes tsawg leeg Lub raj mis iav batch cov ntaub ntawv feem ntau yog tsim los ntawm 7 mus rau 12 raw khoom. Feem ntau muaj quartz xuab zeb, dej qab zib tshauv, limestone, dolomite, feldspar, borax, compounds ntawm txhuas thiab barium, thiab lwm yam. Tsis tas li ntawd, muaj cov khoom pab xws li clarifiers, colorants, decolorizers, thiab opacifiers (saib iav manufacturing). Coarse-grained quartz yog qhov nyuaj rau yaj tag; Yog hais tias cov khoom zoo dhau lawm, cov khib nyiab thiab plua plav yuav raug tsim thaum lub sij hawm melting, uas cuam tshuam rau melting thiab yooj yim blocks lub regenerator ntawm melting rauv. Qhov loj me me yog 0 25-0.5mm. Txhawm rau siv cov iav khib nyiab, iav tawg feem ntau yog ntxiv, thiab nws qhov ntau npaum li cas feem ntau yog 20-60 feem pua, txog li 90 feem pua.
Cov tshuaj muaj pes tsawg leeg ntawm iav fwj thiab jars txawv raws li lawv cov kev xav tau, molding txoj kev, molding ceev, txheej txheem cov yam ntxwv thiab raw khoom ntau yam. Feem ntau ntawm cov fwj thiab hub yog ua los ntawm cov dej qab zib txiv qaub silicate iav. Cov khoom tseem ceeb ntawm dej qab zib kua qaub silicate iav yog SiO2, Na2O thiab CaO. Kev taw qhia txog qhov tsim nyog ntawm Al2O3 thiab MgO tuaj yeem txo cov crystallization ntawm cov iav, txhim kho cov tshuaj lom neeg ruaj khov thiab lub zog ntawm cov iav, thiab txhim kho cov qauv ntawm cov iav. Cov tshuaj muaj pes tsawg leeg ntawm sodium-calcium fwj iav hauv ntau lub teb chaws hauv ntiaj teb yog: SiO2 70-74 feem pua, CaO thiab MgO10-14 feem pua, Na2O thiab K2O13-16 feem pua, Al2O31.{{12 }}.5 feem pua. Thaum tsim cov iav tsis muaj xim thiab cov hub, cov ntsiab lus ntawm Fe2O3 hauv quartz xuab zeb yog tsawg heev (feem ntau yog li ntawm 0.03 feem pua ​​). Hauv cov iav dej qab zib zoo tib yam, ntxiv Cr2O3 thiab Fe2O3, iav yog emerald ntsuab, ntxiv sulfur-carbon lossis MnO2 thiab Fe2O3, iav yog xim av. Lub raj mis thiab hub uas muaj cov tshuaj yuav tsum muaj tshuaj lom neeg ruaj khov thiab ua los ntawm borosilicate iav. Cov fwj tshuaj pleev ib ce qib siab feem ntau yog ua los ntawm cov iav siv lead ua uas muaj cov hlau lead, barium lossis zinc, thiab qee qhov yog iav opalescent, thiab fluoride feem ntau yog siv los ua tus neeg sawv cev opacifying.
