Taw qhia cov khoom siv lub cev ntawm quartz wafers
Quartz ntawv yog qhov tshwj xeeb kev lag luam tshuab iav ua los ntawm silica, uas yog cov khoom siv theem pib zoo heev. Quartz daim hlau muaj cov khoom siv zoo heev rau lub cev thiab tshuaj, xws li:
1. Qhov kub ua haujlwm siab. Qhov muag muag taw tes kub ntawm quartz iav yog li 1730 ° C, thiab nws tuaj yeem siv ntev ntev ntawm 1100 ° C, thiab qhov kub siab siv tshaj plaws tuaj yeem ncav cuag 1450 ° C hauv lub sijhawm luv.
2. Corrosion tsis kam. Tsuas yog zam rau cov hydrofluoric acid, quartz iav kog tsis cuam tshuam nrog lwm cov kua qaub. Nws cov kua qaub tiv taus yog 30 npaug ntawm uas ua haujlwm ntawm ceramic thiab 150 npaug ntawm cov hlau stainless. Tshwj xeeb nws cov tshuaj lom neeg qhov kub ntawm qhov kub thiab txias tsis yooj yim sua rau lwm yam khoom siv engineering. Sib piv.
3. Zoo thermal stability. Lub thermal expansion coefficient ntawm lub iav hloov tau yog qhov tsawg heev, thiab nws tuaj yeem tiv taus qhov kub hloov pauv. Thaum quartz iav yog rhuab kom txog 1100 ° C, nws yuav tsis tawg thaum muab tso rau hauv dej ntawm chav tsev kub.
4. Lub teeb kis tau zoo. Quartz daim hlau muaj lub teeb xa mus zoo rau txhua qhov pom ntawm ultraviolet mus rau infrared, thiab pom lub teeb xa hluav taws xob tau tshaj 93%, tshwj xeeb tshaj yog nyob rau hauv ultraviolet spectrum, qhov siab tshaj plaws transmittance tuaj yeem mus txog saum 80.
