Kev sib xyaw:
Sodium-calcium iav (Soda-Lime Glass) yog ib hom iav uas muaj feem ntau ntawm silicon dioxide (SiO2), sodium oxide (Na2O), thiab calcium oxide (CaO). Nws tuaj yeem muaj lwm cov oxides thiab impurities xws li magnesium oxide (MgO) thiab txhuas oxide (Al2O3).
High-borate silica iav (Borosilicate iav) muaj ntau dua ntawm boron trioxide (B2O3) thiab silicon dioxide (SiO2). Nws feem ntau kuj suav nrog lwm cov oxides xws li alkali hlau oxides (piv txwv li, sodium oxide lossis potassium oxide) thiab alkaline ntiaj teb hlau oxides (xws li calcium oxide lossis magnesium oxide).
Lub cev muaj zog:
Sodium-calcium iav muaj qhov siab dua refractive index thiab qis coefficient ntawm thermal expansion, ua rau nws cov pob tshab thiab yooj yim rau kev ua thiab cov duab. Txawm li cas los xij, nws cov tshuaj lom neeg ruaj khov qis dua, thiab nws muaj kev cuam tshuam los ntawm cov kua qaub, alkalis, thiab lwm yam tshuaj lom neeg.
High-borate silica iav muaj qhov qis qis qis dua thiab qis dua coefficient ntawm thermal expansion. Nws yog kub-resistant ntau dua thiab tuaj yeem tiv taus qhov kub thiab txias ntau yam tsis muaj kev tawg. Tsis tas li ntawd, high-borate silica iav muaj cov tshuaj zoo ruaj khov thiab siab dua rau ntau cov tshuaj.
Daim ntawv thov:
Sodium-calcium iav yog ib hom iav ntau tshaj plaws thiab pom dav siv hauv kev tsim kho kev lag luam, ntim ntim, qhov rais, vaj huam sib luag vaj huam sib luag, thiab lwm yam. Nws kuj yog feem ntau siv rau iav thiab tableware.
Vim nws cov cua kub tsis kam thiab tshuaj lom neeg ruaj khov, cov iav silica high-borate feem ntau yog siv hauv cov cuab yeej kuaj, cov tshuaj tiv thaiv cov hlab ntsha, cov cuab yeej kho qhov muag, cov khoom siv teeb pom kev zoo, lub hnub ci dej rhaub dej, thiab lwm yam kev siv uas yuav tsum tau ua rau kub kub thiab tshuaj corrosion.
