Hauv cov teb xws li kev tsim cov khoom siv thiab kev ntsuas qhov tseeb, cov khoom ntawm cov ntaub ntawv ncaj qha txiav txim siab qhov tseeb ntawm cov khoom siv. Granite, nrog nws tsib yam ntxwv tseem ceeb, sawv tawm ntawm cov ntaub ntawv xws li hlau, cov yas engineering thiab ceramics, thiab tau dhau los ua "tus khub kub" ntawm cov khoom siv siab.
1. Kev ruaj khov ntawm qhov kub thiab txias: Qhov "tiv thaiv" rau qhov kub thiab txias hloov pauv
Rau txhua qhov kev hloov pauv ntawm qhov kub thiab txias 1 ℃, cov hlau tsis xeb nthuav dav los ntawm 17μm / m, cov hlau txhuas nthuav dav los ntawm 23μm / m, thaum granite tsuas yog nthuav dav los ntawm 4-8μm / m. Hauv cov chaw tsim khoom semiconductor, qhov kub siab uas tsim los ntawm kev ua haujlwm ntawm cov tshuab photolithography lossis qhov sib txawv ntawm qhov kub thiab txias ntawm qhov pib thiab nres ntawm cov cua txias muaj cov teebmeem tsis tseem ceeb rau qhov loj ntawm granite. Hauv kev sib piv, qhov kev hloov pauv ntawm cov hlau thiab cov yas vim yog kev nthuav dav thermal thiab kev cog lus tuaj yeem ua rau cov khoom tsis sib xws.
2. Kev tiv thaiv kev co: Tus "Devourer" ntawm lub zog co
Granite muaj qhov ceev siab (2.6-3.1g/cm³), qhov nyuaj ntawm 6-7 ntawm Mohs nplai, thiab qhov piv ntawm damping 5-10 npaug ntawm stainless hlau. Hauv cov khoom siv ntsuas qhov tseeb, nws tuaj yeem txo 90% ntawm lub zog co hauv 0.5 vib nas this, thaum cov khoom siv hlau xav tau 3 txog 5 vib nas this. Kev co los ntawm kev ua haujlwm ntawm cov khoom siv thiab kev txav mus los ntawm cov neeg ua haujlwm hauv lub chaw ua haujlwm nyuaj rau co qhov ruaj khov ntawm cov khoom siv uas txhawb nqa los ntawm granite.
3. Kev ruaj khov tshuaj lom neeg: Tus "tawv ncauj" hauv cov chaw acidic thiab alkaline
Thaum granite raug tsau rau hauv cov kua qaub muaj zog (pH = 2) lossis cov alkali muaj zog (pH = 12) rau 1000 teev, qhov xeb ntawm qhov chaw tsawg dua 0.01μm. Cov hlau tsis xeb yooj yim raug cov kua qaub thiab alkalis, cov hlau txhuas ntshai cov tshuaj alkaline, thiab cov yas engineering yuav o thaum raug cov kuab tshuaj organic. Cov qauv ntom ntawm granite (porosity <0.1%) kuj tseem tuaj yeem tiv thaiv kev kis kab mob, ua rau nws yog "cov khoom xaiv" rau chav ntxuav semiconductor.
4. Kev Ua Haujlwm thiab Tus Nqi: Tus "Tus Tswv ntawm Kev Sib Npaug" ntawm Kev Ua Tau Zoo thiab Kev Ua Tau Zoo ntawm Tus Nqi
Granite tuaj yeem raug zom kom tiaj tus ntawm ≤0.5μm/m thiab qhov roughness ntawm qhov chaw Ra ntawm ≤0.05μm, tab sis kev ua tiav siv sijhawm ntev heev. Cov hlau tsis xeb yooj yim ua tiav tab sis yooj yim rau kev hloov pauv, thaum cov khoom siv ceramic muaj qhov tseeb siab tab sis kim. Hauv cov xwm txheej uas ua raws li qhov tseeb ntawm nanoscale, kev ua tau zoo ntawm granite ntau dua li lwm cov ntaub ntawv.
5. Kev Huv Huv ntawm Cov Hluav Taws Xob: Tus "Ntxuav" ntawm Cov Khoom Siv Hluav Taws Xob
Ua ib yam khoom siv uas tsis yog hlau, granite tsis yog hlau nplaum thiab tsis yog hlau nplaum, thiab yuav tsis cuam tshuam rau cov sensors thiab cov khoom siv hluav taws xob. Cov hluav taws xob conductivity thiab magnetism ntawm cov hlau, cov hluav taws xob static ntawm cov yas engineering, thiab cov dielectric poob ntawm ceramics tag nrho ua "qhov tsis muaj zog" thaum ntsib cov khoom siv precision xws li cov tshuab photolithography thiab cov tshuab nuclear magnetic resonance. Txawm li cas los xij, granite zoo meej rau cov chaw rhiab heev electromagnetic.
Txij li qhov kub siab tiv taus mus rau kev co, los ntawm kev tiv thaiv corrosion mus rau xoom electromagnetic cuam tshuam, granite tau ua pov thawj nrog nws cov khoom siv tawv uas nyob rau hauv thaj chaw ntawm kev tsim khoom precision, nws yog "huab tais" tsis tuaj yeem hloov pauv.
