Beryllium yog ib feem ntawm pawg thib ob tseem ceeb ntawm lub sijhawm thib ob, nrog tus lej atomic ntawm 4 thiab lub cim cim ntawm Be. Nws yog grey-dawb alkaline ntiaj teb hlau. Beryllium thiab nws cov tebchaw muaj tshuaj lom heev. Beryllium yog soluble nyob rau hauv ob qho tib si acid thiab alkali thiab yog amphoteric hlau. Qhov ntom ntawm beryllium zoo ib yam li magnesium, thiab nws cov rigidity yog piv rau cov tungsten. Nws cov ntsiab lus melting yog 1285 degree, thiab nws muaj zog heev thermal neutron scattering peev xwm. Thaum qhov kub thiab txias hloov los ntawm ntau pua degrees, qhov chaw beryllium tseem tuaj yeem tuav lawv qhov loj me.
Daim Ntawv Thov Qhov Zoo ntawm Beryllium X-Ray Transparent Window
1. Kev xa tawm
Ntawm tag nrho cov hlau, beryllium muaj lub peev xwm tshaj plaws los xa cov X-rays. Hlau beryllium yog lub teeb tshaj plaws (tus lej atomic tsawg tshaj plaws) thiab cov hlau ruaj khov tshaj plaws, yog li nws muaj kev tiv thaiv me ntsis ntawm X-rays.
2. Machineability
Lub thermal expansion coefficient ntawm beryllium yog piv rau cov hlau tsis muaj steel thiab Ni-Co alloy, yog li nws muaj kev vuam zoo thiab thermal conductivity zoo. Nyob rau tib lub sijhawm, hlau beryllium tuaj yeem ua kom nyias nyias, thiab lub qhov rais thinnest tsuas yog kaum ntawm microns tuab. Qhov kub ntawm X-ray raj yog siab heev thaum nws ua haujlwm, thiab hlau beryllium tuaj yeem tiv thaiv qhov kub thiab txias.
3. Corrosion kuj
Beryllium tuaj yeem hnov mob nrog oxygen ntawm chav tsev kub los tsim ib qho kev tiv thaiv oxide zaj duab xis rau ntawm nws qhov chaw, yog li nws ruaj khov heev txawm tias thaum nws kub kub hauv huab cua thiab yog insoluble hauv dej. Txawm li cas los xij, nws yog me ntsis soluble hauv dej kub thiab tuaj yeem yaj hauv dilute hydrochloric acid, dilute sulfuric acid, thiab potassium hydroxide tov kom tso hydrogen. Yog li ntawd, thaum siv nws, koj yuav tsum tau them sai sai rau seb puas muaj acidic cua nyob rau hauv ib puag ncig siv. Yog tias muaj, koj yuav tsum tau npog lub qhov rais beryllium nrog ib zaj duab xis tiv thaiv.
Be yog cov khoom uas absorbs tsawg tshaj plaws X-rays, tshwj xeeb tshaj yog mos X-rays, thiab muaj ib tug tej yam mechanical zog, yog li tam sim no nws yog qhov zoo tshaj plaws qhov rais cov ntaub ntawv. Lub thinner txheej txheem ntawm lub qhov rais Beryllium, qhov me me nws cov neeg kho tshuab lub zog, qhov nyuaj ntawm kev ua thiab kev tsim khoom, thiab tus nqi siab dua.
Hauv luv luv, raws li cov khoom siv lub qhov rais ntawm X-ray raj, High Purity Beryllium Window tuaj yeem tsis tsuas yog kaw lub teeb lub teeb, tab sis kuj tswj lub tshuab nqus tsev hauv lub teeb raj. Nyob rau tib lub sijhawm, lub qhov rais beryllium tseem tuaj yeem lim cov X-rays qis rau qee yam. Peb lub tuam txhab feem ntau lees txais cov kev pabcuam customized rau beryllium windows thiab muaj cov khoom siv ntau lawm thiab cov kws tshaj lij, yog li koj tuaj yeem xaj nrog kev ntseeg siab.
