Hoobkas Customized Precision Machining Sapphire
Sapphire muaj qhov nyuaj ntawm Mohs 9, thib ob tsuas yog pob zeb diamond, thiab muaj kev hnav zoo.Nyob rau tib lub sijhawm, nws muaj kev ruaj ntseg zoo heev thiab tuaj yeem tiv thaiv corrosion ntawm yuav luag txhua yam kua qaub thiab alkali.Tsis tas li ntawd, qhov siab tshaj plaws kub tsis kam ntawm sapphire yog 2060 ℃.Vim yog qhov zoo ntawm sapphire saum toj no, sapphire yog siv rau hauv cov cuab yeej thiab cov cuab yeej siv, uas tuaj yeem txhim kho lub neej kev pab cuam thiab tiv taus ntau qhov chaw hnyav.
Sapphire precision qhov feem ntau muaj cov kev xav tau zoo thiab cov txheej txheem sealing meej.Peb tuaj yeem kho ntau yam duab raws li cov neeg siv khoom kos duab.Peb muaj precision txiav, sib tsoo, polishing thiab kuaj cov cuab yeej los xyuas kom meej tias txhua yam khoom ua tau raws li qhov xav tau nruj ntawm cov neeg siv khoom.
Cov Txheej Txheem Tseem Ceeb
Khoom Khoom
Sapphire yog ib qho siv lead ua txhuas oxide (Al2O3).Nws yog ib qho ntawm cov khoom siv nyuaj tshaj plaws.Sapphire muaj cov yam ntxwv kis tau zoo tshaj qhov pom, thiab nyob ze IR spectrum.Nws nthuav tawm cov neeg kho tshuab siab zog, tshuaj lom neeg ua haujlwm, thermal conductivity thiab thermal stability.Nws feem ntau yog siv los ua cov ntaub ntawv qhov rais hauv thaj chaw tshwj xeeb xws li chaw siv tshuab qhov twg khawb lossis kub ua haujlwm yuav tsum tau ua.
