Nyob rau hauv kev tsim kho ntawm precision static siab cua floating platform, kev xaiv ntawm lub hauv paus plays lub luag hauj lwm txiav txim siab nyob rau hauv tag nrho cov kev ua tau zoo ntawm lub platform. Granite precision puag thiab cam khwb cia hlau puag muaj lawv tus kheej cov yam ntxwv, thiab muaj qhov sib txawv ntawm qhov tseem ceeb xws li kev ruaj ntseg, kev saib xyuas raug, durability thiab nqi.
Ua ntej, stability: ntuj ntom thiab hlau qauv
Tom qab ntau lab xyoo ntawm kev hloov geological, granite yog sib xyaw ua ke los ntawm quartz, feldspar thiab lwm yam minerals los tsim cov qauv ntom ntom ntom ntom ntom. Nyob rau hauv lub ntsej muag ntawm kev cuam tshuam sab nraud, xws li kev vibration muaj zog tsim los ntawm kev ua haujlwm ntawm cov cuab yeej loj hauv lub Hoobkas Rhiav, lub hauv paus granite tuaj yeem thaiv thiab txo qis los ntawm kev cia siab rau nws cov qauv siv lead ua nyuaj, uas tuaj yeem txo qhov kev vibration amplitude ntawm precision zoo li qub siab huab cua ntab platform los ntawm ntau dua 80%, muab lub hauv paus ruaj khov rau lub platform kom ntseeg tau tias kev txav mus los thaum ua haujlwm siab. Piv txwv li, nyob rau hauv cov txheej txheem photolithography ntawm cov khoom siv hluav taws xob chips, tus yam ntxwv ntawm cov qauv nti yog lav.
Lub hauv paus hlau cam khwb cia yog cam khwb cia los ntawm hlau-carbon alloy, thiab cov graphite sab hauv yog muab faib rau hauv nplooj ntawv los yog spheres. Txawm hais tias nws muaj qee qhov kev vibration damping muaj peev xwm, nws cov qauv kev sib xws tsis zoo piv nrog granite. Thaum soj ntsuam nrog kev siv siab thiab kev vibration tsis tu ncua, nws yog ib qho nyuaj rau cov cam khwb cia hlau puag kom txo cov kev co cuam tshuam rau tib theem qis li granite puag, uas yuav ua rau me me deviations nyob rau hauv lub zog ntawm precision static siab huab cua floating platform, cuam tshuam rau precision kev ua tau zoo ntawm lub platform nyob rau hauv ultra-precision kev khiav hauj lwm.
Thib ob, kev tuav pov hwm qhov tseeb: lub ntuj zoo ntawm kev nthuav dav qis thiab kev sib tw ntawm cov hlau thermal hloov
Granite paub txog nws cov coefficient tsawg heev ntawm thermal expansion, feem ntau ntawm 5-7 × 10⁻⁶ / ℃. Nyob rau hauv qhov kub thiab txias ib puag ncig, qhov loj ntawm granite precision puag hloov me ntsis. Nyob rau hauv lub tshav pob ntawm astronomy, precision hydrostatic huab cua ntab platform rau qhov zoo tuning ntawm lub tsom iav raj lens yog khub nrog granite puag, txawm tias qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj yog qhov tseem ceeb, nws tuaj yeem xyuas kom meej tias qhov chaw qhov tseeb ntawm lub lens yog khaws cia ntawm qib submicron, pab cov astronomers kom ntes cov kev hloov maj mam ntawm lub cev nyob deb.
Cov coefficient ntawm thermal expansion ntawm cam khwb cia hlau yog qhov siab, feem ntau 10-20 × 10⁻⁶ / ℃. Thaum qhov kub thiab txias hloov, qhov loj ntawm cam khwb cia hlau puag hloov pom tseeb, uas yog ib qho yooj yim ua rau thermal deformation ntawm precision static siab cua floating platform, uas ua rau poob ntawm qhov tseeb txav ntawm lub platform. Nyob rau hauv cov txheej txheem sib tsoo ntawm qhov kub thiab txias-rhiab qhov muag lo ntsiab muag, qhov deformation ntawm cam khwb cia hlau puag nyob rau hauv tus ntawm qhov kub thiab txias yuav ua rau qhov sib txawv ntawm qhov sib tsoo precision ntawm lub lens dhau qhov kev tso cai thiab cuam tshuam rau qhov zoo ntawm lub lens.
Thib peb, durability: siab hardness ntawm ntuj pob zeb thiab hlau qaug zog
Granite hardness siab, Mohs hardness tuaj yeem ncav cuag 6-7, zoo hnav tsis kam. Nyob rau hauv cov ntaub ntawv tshawb fawb soj ntsuam, nquag siv precision static siab cua ntab platform, nws cov granite puag tuaj yeem tiv taus kev sib txhuam mus ntev, piv nrog cov hauv paus zoo tib yam, tuaj yeem txuas ntxiv lub voj voog ntawm lub platform los ntawm ntau dua 50%, txo cov khoom siv tu, thiab xyuas kom muaj kev tshawb fawb txuas ntxiv mus. Txawm li cas los xij, cov khoom siv granite yog nkig, thiab muaj kev pheej hmoo ntawm kev tawg thaum nws raug cuam tshuam.
Lub hauv paus hlau cam khwb cia muaj qee qhov toughness thiab tsis yooj yim rau tawg thaum muaj qee yam cuam tshuam quab yuam. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm lub zog reciprocating zog ntawm precision static siab cua floating platform rau lub sij hawm ntev, cov cam khwb cia hlau yog nquag ua rau qaug zog kev puas tsuaj, ua rau cov kev hloov nyob rau hauv lub internal qauv, muaj feem xyuam rau lub zog thiab stability ntawm lub platform. Nyob rau tib lub sij hawm, cam khwb cia hlau yog nquag xeb thiab corrosion nyob rau hauv ib puag ncig ntub, txo nws cov durability, nyob rau hauv sib piv, granite puag nyob rau hauv corrosion kuj yog zoo dua.
Plaub, raug nqi thiab kev ua haujlwm nyuaj: ntuj pob zeb mining thiab ua cov nyom thiab cov txheej txheem hlau casting
Cov mining thiab kev thauj mus los ntawm granite raw cov ntaub ntawv yog complex, thiab kev ua yuav tsum tau heev high-tech khoom thiab technology. Vim nws cov hardness siab, brittleness, txiav, sib tsoo, polishing thiab lwm yam txheej txheem yog feem ntau ua rau lub cev qhuav dej, kab nrib pleb, siab seem seem, uas ua rau cov nqi tsim khoom siab.
Lub hauv paus hlau cam khwb cia yog tsim los ntawm cov txheej txheem casting mature, ntau qhov chaw ntawm raw khoom thiab tus nqi qis. Los ntawm cov pwm tuaj yeem ua tiav ntau lawm, kev ua haujlwm siab ntau lawm. Txawm li cas los xij, txhawm rau ua tiav tib lub siab precision thiab ruaj khov raws li lub hauv paus granite, cov txheej txheem casting thiab tom qab ua tiav cov txheej txheem yog nruj heev, yuav tsum tau precision machining thiab aging kev kho mob, thiab lwm yam, thiab tus nqi kuj tseem yuav nce siab.
Hauv cov ntsiab lus, granite precision puag muaj qhov zoo hauv daim ntawv thov scenarios ntawm precision zoo li qub siab huab cua ntab platform uas yuav tsum tau siab precision, stability thiab hnav tsis kam; Lub hauv paus hlau cam khwb cia muaj qee qhov zoo ntawm tus nqi thiab tawv, thiab yog qhov tsim nyog rau lub sijhawm uas qhov yuav tsum tau muaj qhov tseeb yog qhov tsawg, kev nrhiav kev ua haujlwm zoo thiab qhov kev vibration thiab kub ib puag ncig yog qhov ruaj khov.
