Borosilicate iav yog ib qho khoom siv roj raw nyob rau hauv cov khoom siv ntawm cov iav Bongs, thiab Quartz iav kuj tseem siv tau ua cov khoom siv raw hauv ntau lawm hauv kev tsim covBong AccessoriesCov. Yog li dab tsi yog qhov sib txawv ntawm ob hom iav?
1. Txawv sib xyaw
Borosilicate iav muaj pes tsawg leeg ntawm cov sodium oxide, thiab silon dioxide, thiab boron thiab silicon cov ntsiab lus hauv lub khob siab: 12.5%, silicon: 78 ~ 80%.
Quartz iav muaj pes tsawg leeg yog silicon dioxide: cov ntsiab lus yog 99.99
2. Txawv kub tsis kam.
Borosilicate kub nyob rau hauv txoj hlab kub ntawm 520 degrees, softening kub ntawm 820 degrees
Quartz iav kub txog 1100 degrees melting point yog txog 1700 degrees.
3. Cov tshuaj sib txawv
Quartz iav tsis yog tiv thaiv siab rau qhov kub siab, tab sis kuj tiv taus cov kua qaub, xeb. Rwb thaiv hluav taws xob zoo, thiab lwm yam.
Quartz iav yog ib qho -}} sib xyaw ua silica tshwj xeeb muaj iav. Lub hardness ntawm cov iav no tuaj yeem nce mus txog xya mohs, nrog cov hluav taws xob kub, thiab muaj cov hluav taws xob hluav taws xob tsis ruaj khov, thiab muaj peev xwm hloov hluav taws xob ultraviolet thiab cov hluav taws xob infrariolet thiab infrared. Ntxiv nrog rau hydrofluoric acid, kub phosphoric acid, cov kua qaub dav dav uas muaj cov kua qaub zoo. Raws li cov pob tshab, nws tau muab faib ua ob pawg: pob tshab thiab opaque. Raws li lub purity, nws tau muab faib ua peb pawg: kev coj dawb huv, ntau yam, thiab doped. Crystal, silica, cov khoom muag zoo li cov khoom siv raw, qhov siab kub yaj lossis tshuaj vapor deposition. Melting txoj kev muaj xws li hluav taws xob thiab roj ua kom zoo nkauj.
High borosilicate iav (tseem muaj lub iav nyuaj) yog siv cov iav kub ntawm lub iav kom ua tiav cov khoom siv hluav taws xob, los ntawm cov khoom siv hluav taws xob ntawm lub iav, los ntawm cov khoom siv hluav taws xob ntawm (3.10) * Nws yog cov khoom siv iav tshwj xeeb nrog tus nqi nthuav dav, muaj kev cuam tshuam kub, thiab siab siv tshuaj lom neeg hauv ntau yam kev lag luam vim nws qhov kev ua tau zoo heev.
