Kev siv thiab cov yam ntxwv ntawm iav raj
Cov iav raj yog ib hom tsis yog hlau raj hauv lus Askiv, sodium oxide (Na2O), boron oxide (B2O3), silicon dioxide (SiO2) raws li cov ntsiab lus ntawm ib hom iav. Nws cov kev ua tau zoo tau raug lees paub thoob plaws ntiaj teb, piv nrog cov iav ntau, tsis muaj kev phom sij, nws cov khoom siv hluav taws xob, thermal stability, dej tsis kam, alkali tsis kam, acid tsis kam thiab lwm yam khoom muaj zog, uas tuaj yeem siv dav hauv tshuaj lom neeg. kev lag luam, aerospace, tub rog, tsev neeg, tsev kho mob thiab lwm yam kev lag luam, muaj kev txhawb nqa zoo thiab cov txiaj ntsig kev sib raug zoo, Cov tsos ntawm cov iav zoo li no hauv peb lub teb chaws yog lwm qhov kev hloov pauv tshiab ntawm cov khoom siv hauv kev lag luam.
Lub linear expansion coefficient ntawm G3.3 siab borosilicate iav yog 3.3 kg 0.1 × 10-6/K, uas yog ib hom iav nrog sodium oxide (Na2O), boron oxide (B2O3) thiab silicon Dioxide (SiO2) yog cov khoom tseem ceeb. Cov ntsiab lus ntawm borosilicate nyob rau hauv iav muaj pes tsawg leeg yog siab, raws li boron: 12.5 ~ 13.5 feem pua, silicon: 78 ~ 80 feem pua, yog li hom iav no hu ua siab borosilicate iav. PYREX iav ntawm borosilicate iav. Acid kuj, alkali tsis kam, dej tsis kam, zoo heev corrosion kuj, nrog zoo thermal stability, tshuaj stability thiab hluav taws xob zog, yog li nws muaj chemical yaig kuj, thermal cuam tshuam tsis kam, zoo mechanical zog, kub withstand yam ntxwv.
