Cov iav raj feem ntau siv iav borosilicate siab.
Lub linear expansion coefficient ntawm G3.3 siab borosilicate iav yog 3. Dioxide (SiO2) yog cov khoom tseem ceeb. Cov ntsiab lus ntawm borosilicate nyob rau hauv iav muaj pes tsawg leeg yog siab, feem, boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%, yog li nws yog hu ua siab borosilicate iav. PYREX iav belongs rau borosilicate iav. Acid, alkali thiab dej tsis kam, zoo heev corrosion kuj, nrog zoo thermal stability, tshuaj stability thiab hluav taws xob zog, yog li nws muaj tshuaj yaig tsis kam, thermal shock resistance, zoo mechanical zog, kub kub kuj yam ntxwv.
Piv nrog rau cov iav sib txawv, tsis muaj kev phom sij, nws cov khoom siv hluav taws xob, thermal stability, dej tsis kam, alkali tsis kam, acid kuj thiab lwm yam khoom zoo heev, tuaj yeem siv dav hauv tshuaj lom neeg, aerospace, tub rog, tsev neeg, tsev kho mob thiab lwm yam kev lag luam. yuav ua rau lub teeb, cov cim, tsom iav, lub tshuab ntxhua khaub ncaws saib lub qhov, microwave phaj, hnub ci dej rhaub thiab lwm yam khoom, nrog rau kev txhawb nqa zoo thiab cov txiaj ntsig zoo.
