Hauv cov teb ntawm kev tsim khoom siab thiab kev tsim kho kom raug, lub neej ua haujlwm ntawm cov khoom siv khoom siv yog ncaj qha cuam tshuam nrog kev ruaj khov ntawm kev tsim khoom thiab cov nqi ua haujlwm. ZHHIMG granite Cheebtsam, nrog rau qhov ceev ceev ntawm 3.1g / cm³ thiab qhov zoo tshaj plaws elastic modulus ntawm 50GPa, tau tawg los ntawm cov kev txwv ntawm cov ntaub ntawv ib txwm muaj, ua tiav lub neej ua haujlwm ntau dua 30 xyoo thiab dhau los ua "lub sijhawm ntev" hauv kev siv hauv kev lag luam. Cov ntsiab cai ntawm kev tshawb fawb khoom siv tom qab nws qhia txog kev sib txuas tob ntawm kev ua tau zoo thiab kev ua haujlwm ntev.
1. Qhov ceev ntawm 3.1g/cm³: Cov qauv ntom ntom ua rau lub hauv paus ruaj khov
Qhov ceev ntawm ZHHIMG granite Cheebtsam yog los ntawm lawv cov khoom siv minerals tshwj xeeb thiab cov txheej txheem tsim geological. Granite feem ntau yog tsim los ntawm cov pob zeb siv lead ua xws li quartz, feldspar thiab mica sib xyaw ua ke. Nyob rau hauv qhov chaw geological ntawm qhov kub thiab txias siab thiab siab siab, cov minerals no tau crystallized thiab compacted rau ntau pua lab xyoo, tsim ib qho qauv ntom ntom ze li ntawm pore-free (porosity < 0.1%). Qhov compactness no muab cov Cheebtsam nrog peb qhov zoo tseem ceeb:
Kev tiv thaiv kev hnav zoo heev: Qhov ceev ceev txhais tau tias cov atoms ntawm qhov chaw ntawm cov khoom siv tau teeb tsa ze ze, ua rau nws tsis yooj yim hnav thiab khawb thaum lub sijhawm ntev sib txhuam lossis kev sib cuag. Piv txwv li, hauv kev siv cov cuab yeej siv tshuab precision, ZHHIMG granite Cheebtsam tuaj yeem tiv taus ntau dua ib lab qhov kev txav mus los, nrog rau qhov poob qhov tseeb ntawm qhov chaw tsawg dua 0.01μm, ntau dua li cov khoom siv ib txwm muaj xws li hlau cam khwb cia.
Kev tiv thaiv xeb zoo dua: Cov qauv ntom ntom no ua rau cov tshuaj lom neeg sab nraud tsis nkag mus. Txawm hais tias nws yog cov tshuaj reagents acid thiab alkali, cov roj pleev xim rau kev lag luam lossis huab cua noo, qhov ruaj khov ntawm cov tshuaj lom neeg ntawm ZHHIMG granite tsis cuam tshuam. Nws qhov pH kam rau siab yog 1-14, thiab nws tuaj yeem siv tau ntev hauv qhov chaw kub heev yam tsis muaj xeb.
Kev ruaj khov ntawm qhov ntev: Cov khoom siv uas muaj cov khoom ntom ntom muaj cov thermal conductivity tsawg, ua rau nws nyuaj rau cua sov kom tawg sai hauv cov khoom, yog li txo qhov kev ntxhov siab thermal uas tshwm sim los ntawm kev hloov pauv kub. Ua ke nrog nws cov coefficient thermal expansion qis li (4-8) × 10⁻⁶ / ℃, qhov kev hloov pauv ntawm ZHHIMG granite Cheebtsam yeej ib txwm tswj hwm ntawm qib micrometer hauv qhov kub ntawm -40 ℃ txog 120 ℃, kom ntseeg tau tias siv tau ntev.
II. 50GPa Elastic Modulus: Ib qho txuj ci tseem ceeb ntawm kev sib xyaw ua ke ntawm kev ruaj khov thiab kev ywj pheej
Lub elastic modulus qhia txog lub peev xwm ntawm cov khoom siv los tiv thaiv kev hloov pauv elastic. Lub 50GPa elastic modulus ntawm ZHHIMG granite Cheebtsam ua rau lawv pom tau tias muaj "kev sib xyaw ua ke ntawm kev nruj thiab kev yooj ywm" thaum raug rau cov khoom thauj:
Kev ruaj khov siab kom tiv taus kev hloov pauv: Thaum ntsib kev nyuaj siab ntev lossis kev co siab los ntawm cov khoom siv hnyav, qhov elastic modulus ntawm 50GPa ua kom ntseeg tau tias cov khoom tsuas yog dhau los ntawm kev hloov pauv elastic tsawg kawg nkaus. Piv txwv li, hauv kev siv cov platform tshuaj xyuas lub cav aero, cov khoom siv granite ZHHIMG tuaj yeem txhawb nqa cov khoom siv tshuaj xyuas uas hnyav dua 2 tons, thiab qhov sib txawv ntawm qhov tiaj tiaj yog tswj tau hauv ± 0.1μm / m, ua kom ntseeg tau tias qhov ntsuas raug rau ntau xyoo caum.
Kev ntxhov siab buffering kom tiv thaiv kev tawg: Lub modulus elastic siab tsis tas txhais tau tias cov khoom siv yog brittle lossis tawv. Cov qauv siv lead ua hauv granite muab nws nrog lub peev xwm tshwj xeeb dispersion kev ntxhov siab. Thaum raug rau cov khoom thauj, cov khoom tuaj yeem buffer lub zog los ntawm kev hloov pauv me ntsis ntawm cov siv lead me me, zam kev tawg los ntawm kev ntxhov siab concentration. Ib qho kev ntsuas tiag tiag ntawm ib lub tuam txhab tsim khoom semiconductor qhia tau hais tias ZHHIMG granite bearing platform tsis tau raug kev puas tsuaj tom qab raug kaum tawm txhiab tus neeg poob siab.
Iii. Cov Txuj Ci Ua Haujlwm Txog Kev Tshawb Fawb: Tso Tawm Lub Peev Xwm Zoo Tshaj Plaws ntawm cov ntaub ntawv
Ntxiv rau qhov zoo ntawm cov khoom siv, ZHHIMG cov thev naus laus zis ua tiav ultra-precision ntxiv unleashes lub peev xwm ua tau zoo ntawm granite. Los ntawm cov txheej txheem xws li magnetorheological polishing thiab ion beam grinding, qhov roughness ntawm qhov chaw ntawm cov khoom tuaj yeem txo qis rau Ra≤0.02μm, thiab qhov flatness tuaj yeem ncav cuag ± 0.1μm / m. Qhov kev ua tiav siab no tsis yog tsuas yog txo cov qhov tsis zoo ntawm qhov chaw tab sis kuj zam kev siv lub neej attenuation los ntawm micro-cracks, ua rau cov khoom siv ua tau zoo kom ruaj khov rau lub sijhawm ntev.
Txij li qhov ceev ntawm 3.1g/cm³ mus rau qhov txhawb nqa modulus ntawm 50GPa, ZHHIMG granite Cheebtsam siv cov ntaub ntawv tshawb fawb ua lub hauv paus thiab sib xyaw cov khoom ntuj tsim nrog cov thev naus laus zis tshiab. Nrog lub neej ua haujlwm ntau tshaj 30 xyoo, nws tsis tsuas yog txo cov nqi hloov khoom siv rau cov lag luam, tab sis kuj txhawb kev nce qib ntawm kev tsim khoom kom raug mus rau kev ua haujlwm ntev thiab kev ntseeg siab siab, ua tus qauv ntawm "kev nqis peev ib zaug, cov txiaj ntsig tas mus li" hauv kev lag luam.
