High borosilicate yog hais txog cov iav borosilicate siab, siab borosilicate iav feem ntau muaj tshuaj lom neeg ruaj khov thiab kub tsis kam, yog li nws feem ntau tsis muaj teeb meem rau tib neeg lub cev.
Cov khoom tseem ceeb ntawm cov iav borosilicate siab yog boron trioxide thiab silicon dioxide, uas feem ntau yog siv los ua iav, thiab tuaj yeem tiv taus qhov kub thiab txias ntawm li 520 degree, nrog rau cov yam ntxwv ntawm qhov kub thiab txias, thiab yuav tsis tawg tom qab cua sov, thiab cov txheej txheem siv yog kev nyab xeeb dua. Nyob rau tib lub sijhawm, iav borosilicate siab kuj muaj qhov zoo ntawm cov kua qaub thiab alkali tsis kam, thiab yuav tsis cuam tshuam rau kev noj qab haus huv vim muaj kev cuam tshuam ntawm lwm yam tshuaj thaum siv. Tsis tas li ntawd, lub iav borosilicate siab kuj muaj qhov zoo ntawm qhov chaw du, yooj yim los ntxuav, tsis yooj yim rau cov kab mob thiab cov av, yog li kev siv cov iav borosilicate siab kuj zoo rau tib neeg lub cev, yuav tsis ua mob, tsis tas yuav tsum tau ua. txhawj ntau dhau.
