Kev Taw Qhia Txog Quartz Iav

iav quartzyog ib lub iav tshwj xeeb hauv kev lag luam uas ua los ntawm silicon dioxide thiab yog ib yam khoom siv yooj yim zoo heev.

Nws muaj ntau yam khoom zoo heev ntawm lub cev thiab tshuaj lom neeg, xws li:

1. Kev kub siab tsis kam

Qhov kub ntawm cov iav quartz yog li 1730 degrees C, siv tau ntev ntawm 1100 degrees C, thiab siv tau luv luv ntawm 1450 degrees C.

2. Kev tiv thaiv xeb

Ntxiv rau hydrofluoric acid, quartz iav yuav luag tsis muaj tshuaj lom neeg nrog lwm cov tshuaj acid, nws cov kua qaub corrosion tuaj yeem zoo dua li cov kua qaub-resistant ceramics 30 zaug, zoo dua li stainless hlau 150 zaug, tshwj xeeb tshaj yog nyob rau hauv qhov kub siab tshuaj lom neeg ruaj khov, tsis muaj lwm yam khoom siv engineering tuaj yeem piv.

3. Kev ruaj khov zoo.

Lub coefficient ntawm thermal expansion ntawm quartz iav yog me heev, tuaj yeem tiv taus qhov kub hloov pauv loj heev, quartz iav yog cua sov txog li 1100 degrees C, muab tso rau hauv dej sov yuav tsis tawg.

4. Kev ua tau zoo ntawm lub teeb kis tau zoo

Cov iav quartz hauv tag nrho cov spectral band los ntawm ultraviolet mus rau infrared muaj kev ua tau zoo ntawm lub teeb kis tau zoo, pom lub teeb kis tau ntau dua 92%, tshwj xeeb tshaj yog nyob rau hauv thaj chaw ultraviolet spectral, qhov kis tau tus nqi tuaj yeem ncav cuag ntau dua 80%.

5. Kev ua haujlwm rwb thaiv hluav taws xob zoo.

Quartz iav muaj tus nqi tsis kam sib npaug rau 10,000 npaug ntawm cov iav ib txwm muaj, yog cov khoom siv hluav taws xob zoo heev, txawm tias thaum kub siab kuj muaj kev ua tau zoo hluav taws xob.

6. Lub tshuab nqus tsev zoo

Cov pa roj permeability qis; lub tshuab nqus tsev tuaj yeem ncav cuag 10^-6Pa

Quartz iav ua "Crown" ntawm txhua yam iav sib txawv, nws tuaj yeem siv rau ntau yam:

• Kev sib txuas lus kho qhov muag
• Cov khoom siv semiconductor
• Cov khoom siv photovoltaic
• Lub teeb hluav taws xob teb
• Kev tsav dav hlau thiab lwm yam
• Kev tshawb fawb hauv chav kuaj

Saida Glass yog ib lub tuam txhab ua iav thoob ntiaj teb uas paub zoo, muaj nqe sib tw, thiab xa khoom raws sijhawm. Peb muab kev kho kom haum rau ntau yam iav thiab tshwj xeeb hauv ntau hom iav quartz/borosilicate/float.
