Lub zog tensile ntawm iav fiber ntau ntau zaus ntau dua li ntawm cov iav ntau, tab sis kev tshawb fawb tau pom tias cov qauv ntawm iav fiber yog tib yam li iav. Cov kev xav txog cov qauv iav kom deb li deb tuaj yeem cuam tshuam qhov xwm txheej tiag tiag yog&"; microcrystalline qauv kev xav &"; thiab" network qauv kev xav".
Cov qauv txheej txheem microcrystalline ntseeg hais tias iav yog tsim los ntawm silicic acid blocks lossis&"microcrystals &"; ntawm silicon dioxide, thiab&"crystallites &"; tau ntim nrog cov tshuaj supercooled ntawm silicic acid block.
Cov qauv txheej txheem kev ntseeg ntseeg tias iav yog qhov tsis sib thooj peb-seem network ntawm tetrahedrons, alumina trihedrons lossis boron-oxygen trihedrons ntawm silica, thiab qhov khoob ntawm cov tes hauj lwm tau sau nrog cations xws li Na, K, Ca, Mg, thiab lwm yam. peb-txheej txheem txheej txheem ntawm silica tetrahedron yog lub hauv paus rau kev txiav txim siab cov yam ntxwv ntawm iav, thiab cov cations uas tau sau xws li Na thiab Ca tau hu ua kev hloov pauv network.
Cov ntaub ntawv ntau ua pov thawj tias cov qauv iav yog kwv yees kwv yees. Qhov laj thawj yog tias muaj qee tus lej thiab qhov loj ntawm thaj tsam uas tau npaj ua ntu zus hauv cov qauv iav. Txoj cai no yog tshwm sim los ntawm qee tus lej ntawm polyhedrons tom qab kev teeb tsa ib txwm muaj cov qauv siv lead ua zoo sib xws. Txawm li cas los xij, thaj tsam xaj tsis nruj me ntsis raws li cov qauv siv lead ua. Lawv tsis zoo ib yam ntawm qib me me, tab sis zoo ib yam ntawm qib macroscopic, cuam tshuam txog cov khoom isotropic ntawm iav.
