Taw qhia cov ntaub ntawv raw ntawm cov fwj iav

Ntau cov ntaub ntawv siv los npaj tsom iav yog suav sau ua cov khoom siv iav. Kwv yees muaj li ntawm 7-12 yam, muaj 4-6 yam ntawm cov khoom siv tseem ceeb, xws li quartz xuab zeb, limestone, feldspar, dej qab zib tshauv, boric acid, cov tshuaj tiv thaiv cov tshuaj txhuas, barium tebchaw, thiab lwm yam Raws li lub luag haujlwm ntawm kev qhia oxides hauv lub iav qauv, lawv tuaj yeem muab faib tau Nws yog cov khoom siv ntawm iav tsim oxide, cov khoom raw ntawm cov hlau oxide nruab nrab, thiab cov khoom siv raw ntawm network sab cev lub cev oxide. Raws li cov xwm txheej ntawm cov pa oxide qhia, nws tuaj yeem muab faib ua cov khoom siv ntawm cov tshuaj tiv thaiv acidic thiab cov khoom nyoos ntawm alkali hlau oxide. Cov ntaub ntawv pob khoom yog cov khoom siv rau iav kom tau qee yam khoom tsim nyog thiab ua kom nrawm nrawm. Txawm hais tias qhov nyiaj tsawg tsawg, qhov ua tau zoo yog qhov tseem ceeb heev. Cov khoom siv pabcuam no tau muab faib ua cov lus meej, fluxes, colorants, decolorants, opacifiers, thiab oxidizers. , Txo tus neeg sawv cev, thiab lwm yam kev sib txawv ntawm cov khoom siv zoo ib yam, keeb kwm sib txawv ntawm cov khoom siv tib thiab cov ntsiab lus sib txawv hauv cov ntsiab lus yuav cuam tshuam tag nrho cov khoom zoo thiab cov nqi tsim khoom. Thaum cov khoom siv raw qhov sib txawv me me, nws yog qhov nyuaj rau cov kua dej ntim fwj kom ua rau muaj qhov sib txawv thaum sib piv cov qauv. Qhov txawv tsuas yog pom hauv cov ntau lawm.
