Cov tshuaj muaj pes tsawg leeg ntawm cov iav zoo tib yam yog Na2SiO3, CaSiO3, SiO2 lossis Na2O·CaO·6SiO2, thiab lwm yam.
Lub ntsiab tivthaiv yog silicate ob ntsev, uas yog ib tug amorphous khoom nrog random qauv.Nws yog dav siv nyob rau hauv lub tsev los thaiv cua thiab lub teeb, thiab belongs rau ib tug sib tov.
Kuj tseem muaj cov iav xim sib xyaw nrog oxides lossis ntsev ntawm qee yam hlau los qhia cov xim, thiab cov iav tempered tau los ntawm kev siv lub cev lossis tshuaj.
Cov iav fwj thiab cov kaus poom yuav tsum muaj qee yam kev ua tau zoo thiab ua tau raws li cov qauv zoo.
① iav zoo: ntshiab thiab zoo ib yam, tsis muaj qhov tsis xws luag xws li xuab zeb, streaks, thiab npuas.Cov iav tsis muaj xim muaj qhov pom tseeb;cov xim ntawm cov xim iav yog qhov sib xws thiab ruaj khov, thiab tuaj yeem nqus lub teeb lub zog ntawm qee qhov wavelength.
② Lub cev thiab cov khoom siv tshuaj lom neeg: Nws muaj qee qhov kev ruaj ntseg tshuaj thiab tsis cuam tshuam nrog cov ntsiab lus.Nws muaj qee qhov kev poob siab thiab kev ua haujlwm ntawm lub zog, thiab tuaj yeem tiv taus cua sov thiab txias txheej txheem xws li ntxuav thiab kom tsis muaj menyuam, nrog rau kev ua kom puv, khaws cia thiab kev thauj mus los, thiab tuaj yeem nyob twj ywm tsis muaj kev puas tsuaj thaum ntsib kev ntxhov siab sab hauv thiab sab nraud, kev co, thiab cuam tshuam.
③Forming zoo: tuav ib qho ntim, qhov hnyav thiab cov duab, cov phab ntsa tuab, du thiab tiaj tus lub qhov ncauj kom paub meej tias yooj yim sau thiab sealing zoo.Tsis muaj qhov tsis zoo xws li distortion, tsis sib xws, tsis sib xws thiab tawg.
