Nta ntawm High Borosilicate iav

Lub linear expansion coefficient ntawm G3.3 borosilicate iav yog 3.3 ± 0.1 × 10-6 / K, uas yog ib hom iav nrog sodium oxide (Na2O), boron oxide (B2O3) thiab silicon dioxide (SiO2) raws li lub hauv paus Cheebtsam. Cov ntsiab lus ntawm borosilicate nyob rau hauv cov iav muaj kuj yog siab, uas yog boron: 12.5 ~ 13.5 feem pua, silicon: 78 ~ 8 0 feem pua, yog li hom iav no hu ua siab borosilicate iav. Nws belongs rau PYREX iav hauv borosilicate iav. Acid kuj, alkali tsis kam, dej tsis kam, zoo heev corrosion kuj, zoo thermal stability, tshuaj stability thiab hluav taws xob zog, yog li nws muaj cov yam ntxwv ntawm cov tshuaj corrosion kuj, thermal poob siab kuj, zoo mechanical zog, thiab kub kam rau ua. High borosilicate iav (tseem hu ua iav tawv) kuj hu ua "borosilicate iav 3.3" vim nws cov kab hluav taws xob thermal expansion coefficient ntawm (3.3 ±{28}}.1) × 10-6/K. Nws yog cov khoom siv iav tshwj xeeb uas tsis tshua muaj qhov nthuav dav, kub tsis kam, siab zog, siab hardness, siab transmittance thiab tshuaj lom neeg ruaj khov. Vim nws txoj kev ua tau zoo heev, nws tau siv dav hauv hnub ci zog, tshuaj lom neeg kev lag luam, ntim tshuaj, hluav taws xob lub teeb, khoom siv tes ua khoom siv tes ua thiab lwm yam lag luam. Nws qhov kev ua tau zoo tau raug lees paub los ntawm txhua qhov chaw ntawm lub neej hauv ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv thaj chaw ntawm lub hnub ci zog, uas yog siv ntau dua hauv cov teb chaws tsim kho xws li lub teb chaws Yelemees thiab Tebchaws Meskas. Cov kab hluav taws xob thermal expansion coefficient ntawm borosilicate iav 3.3 yog (3.3 ± 0.1) × 10-6 / K, thiab nws cov kev qhia tseem ceeb ntawm txhua qhov ua tau raws li cov qauv thoob ntiaj teb ISO, uas yog tib yam li 7740 cov khoom ntawm Corning Company hauv United. Lub xeev thiab cov khoom 50 ntawm German Schott Company. poj niam deev. Piv nrog rau cov iav zoo tib yam, nws tsis muaj tshuaj lom thiab phiv, thiab nws cov khoom siv kho tshuab, thermal stability, dej tsis kam, alkali tsis kam, acid kuj thiab lwm yam khoom zoo heev. Nws tuaj yeem siv dav hauv tshuaj lom neeg, aerospace, tub rog, tsev neeg, tsev kho mob thiab lwm yam. Nws tuaj yeem siv rau hauv ntau yam khoom xws li teeb, qauv daim hlau, daim iav tsom iav, lub tshuab ntxhua khaub ncaws saib qhov, microwave qhov cub daim hlau, hnub ci dej rhaub, thiab lwm yam. Nws muaj kev txhawb nqa zoo thiab muaj txiaj ntsig zoo. Cov tsos ntawm hom iav no hauv kuv lub teb chaws yog lwm qhov kev hloov pauv tshiab hauv kev lag luam cov ntaub ntawv yooj yim.
