Yam khoom zoo li cas rau cov zaub mov qib iav fwj?
Qhov zoo ntawm cov iav fwj tuaj yeem siv tau ua lub hauv paus rau kev cai lij choj hauv lub teb chaws. Ib feem ntau ntawm cov iav fwj siv los tuav cov khoom noj thiab dej haus. Ntxiv nrog rau cov kev ntsuas xws li cov tsos zoo, qhov yuav tsum tau rau cov iav fwj tseem ceeb dua thermal thiab tshuaj stability ntawm cov khoom. Vim hais tias cov iav fwj muaj cua ntsawj thaum sov siab ua ntej kom puv, thermal stability siab rau cov khoom no. Muaj cov txiv qaub, cov noob taum fermented thiab lwm cov khoom, kom khaws tau cov khoom zoo, cov iav fwj yuav tsum tau muaj kev ruaj ntseg khov kho.
Ntau yam ntaub ntawv siv rau kev npaj cov ntaub iav los ua ke yog sau los ua cov ntaub ntawv khob iav. Nws muaj 7-12 hom, 4-6 hom ntaub ntawv tseem ceeb, xws li cov quartz xuab zeb, limestone, feldspar, soda tshauv, boric acid, lead compounds, barium compounds, etc., uas tau muab faib raws li lub luag hauj lwm ntawm lub cob tau oxide nyob rau hauv cov iav qauv. Cov ntaub ntawv raw cov txheej txheem oxides ntawm iav, cov ntaub ntawv raw cov vas sab oxides, thiab cov sab nrauv sab nrauv oxide tau muab cais ua cov ntaub ntawv raw cov kua qaub thiab oxid hlau oxides raws li cov khoom ntawm cov oxides oxide.
Batching yog raw khoom rau iav kom tau qee yam khoom tsim nyog thiab ua kom tiav cov txheej txheem melting. Txawm hais tias tus nqi tsawg, cov nyhuv tseem ceeb heev. Cov ntaub ntawv pabcuam yog muab cais rau hauv cov taub, cov kua nplaum, cov xim, cov tshuaj ntxuav muag, cov tshuaj tua kab, thiab cov oxidizers. , txo tus neeg sawv cev thiab ua li ntawd.
Sib txawv ntawm cov khoom qub, txawv keeb kwm ntawm raw cov ntaub ntawv, thiab cov ntsiab lus ntawm cov khoom sib xws yuav cuam tshuam cov khoom tsim thiab cov nqi tsim nqi. Nyob rau hauv rooj plaub twg cov nqi raw cov nqi tsis zoo sib txawv, lub khob fwj tsim muaj peev xwm ua qhov txawv txav thaum sib txawv me me. Tsuas yog thaum batch khoom ua tau ua tau qhov txawv yuav pom.
