Rau ntau tus kws tshaj lij, nrhiav cov khoom siv uas tuaj yeem ua tiav nyob ze - xoom thermal expansion, lav qhov ruaj khov nyob mus ib txhis, thiab tseem yog qhov tseeb- ua haujlwm rau hauv cov duab nyuaj ib txwm yog qhov nyuaj heev. Qhov ntawd yog, txog thaum lawv ntsib Zerodur. Raws li cov chaw tsim khoom tau nkag siab tob rau hauv thaj chaw tshwj xeeb ceramics, peb tsis tsuas yog muab cov khoom siv saum toj kawg nkaus no -tier tab sis kuj tau cog lus rau machining nws mus rau hauv cov khoom tseem ceeb uas ua rau kev txhim kho thev naus laus zis.
Zerodur® yog dab tsi? Vim li cas thiaj hu ua "Dimensionally Eternal" Material?
Zerodur® yog iav -ceramic composite. Nws tsis yog sintered ceramic nyob rau hauv cov kev xav ib txwm muaj tab sis yog iav -ceramic composite tsim los ntawm cov txheej txheem tshwj xeeb uas tswj cov crystallization. Nws qhov tseem ceeb tshaj plaws, cov yam ntxwv ntawm kev hloov pauv yog:
Zero -Zero Coefficient of Thermal Expansion (CTE): Ntau qhov kub thiab txias (tshwj xeeb nyob ib puag ncig ntawm chav sov), nws cov thermal expansion coefficient qis heev (0 ± 0.1 × 10⁻⁶/K). Qhov no txhais tau hais tias qhov kub thiab txias tsis tshua muaj kev hloov pauv ntawm cov khoom. Rau cov tshuab kho qhov muag thiab siab -cov cuab yeej ua kom raug, qhov no yog txoj kab kev ua neej kom tsis txhob muaj kev ua haujlwm drift thiab tuav ntev - lub sij hawm raug.
Zoo heev Machinability: Ua ntej qhov kawg crystallization stabilization, Zerodur blanks yuav ua tau yooj yim zoo li tus thiab ua ntej machined siv tsoos glassworking cov tswv yim (xws li txiav, drilling, sib tsoo, polishing). Tom qab precision annealing thiab crystallization kev kho mob tom qab ntawd ua tiav lub xeev ruaj khov kawg, ua kom cov geometries nyuaj thiab ua tiav qhov siab (txog daim iav zoo).
High Hardness thiab Stability: Tom qab ua tiav crystallization, cov khoom muaj siab hardness, siab rigidity, tsawg ntom, zoo heev tshuaj stability, tsis yog - ntxeem tau, thiab yog resistant rau deformation los yog aging.
Superior Optical Homogeneity: Raws li qhov saum toj kawg nkaus - cov khoom siv kho qhov muag, nws cov qauv sab hauv yog qhov sib xws, nrog kev xa tawm zoo lossis kev cuam tshuam, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau siab -kev ua haujlwm kho qhov muag.
Plaub Ntug -Edge Application Fields: Yuav Ua Li Cas Zerodur® Defines Performance Limits
