Hauv kev tsim cov khoom siv hluav taws xob uas yooj ywm (FPC) tsim, cov khoom siv txiav laser yog ib qho cuab yeej tseem ceeb rau kev ua tiav cov txheej txheem zoo, thiab lub platform granite, ua nws lub hauv paus, ua lub luag haujlwm tseem ceeb.
Kev ruaj khov thermal zoo heev
Thaum lub sijhawm txiav FPC laser, lub tshuab hluav taws xob laser tsim cov cua sov ntau heev, thiab tib lub sijhawm, kev ua haujlwm ntev ntawm cov khoom siv kuj tseem yuav ua rau qhov kub nce siab. Granite muaj cov coefficient qis heev ntawm kev nthuav dav thermal, feem ntau tsuas yog (4-8) × 10⁻⁶ / ℃. Qhov no txhais tau tias txawm tias nyob rau hauv ib puag ncig ua haujlwm nrog kev hloov pauv kub loj, qhov kev hloov pauv ntawm lub platform granite yog me me heev. Piv nrog rau lwm cov ntaub ntawv, piv txwv li, cov hlau muaj kev hloov pauv loj heev thaum qhov kub hloov pauv, uas tuaj yeem cuam tshuam rau qhov tseeb ntawm qhov chaw ntawm lub taub hau txiav thiab daim ntawv FPC. Lub platform granite tuaj yeem tswj tau qhov loj me ruaj khov, muab qhov chaw qhia meej rau lub taub hau txiav, xyuas kom meej tias qhov tseeb ntawm kev txiav tseem nyob rau theem siab txhua lub sijhawm, zam kev txiav kev hloov pauv los ntawm kev hloov pauv thermal, thiab lav qhov tseeb ntawm qhov ntev thiab kab ncaj ncees ntawm cov khoom FPC.
Muaj zog tiv thaiv kev co
Thaum lub sijhawm txiav laser, kev txav ceev ntawm lub taub hau txiav thiab cov nyhuv ntawm laser pulses tuaj yeem tsim kev co. Tsis tas li ntawd, kev ua haujlwm ntawm lwm yam khoom siv hauv lub Hoobkas ua haujlwm kuj tseem tuaj yeem ua rau muaj kev cuam tshuam kev co ntawm ib puag ncig. Cov qauv sab hauv ntawm granite yog ntom, thiab cov khoom siv lead ua ke zoo sib xyaw ua ke. Nws muaj cov yam ntxwv zoo heev thiab tuaj yeem nqus thiab tiv thaiv kev co. Kev tshawb fawb qhia tau tias cov platform granite tuaj yeem txo qhov kev co amplitude ntau dua 90% hauv lub sijhawm luv luv. Qhov kev ua tau zoo tiv thaiv kev co no tuaj yeem tiv thaiv kev co los ntawm kev xa mus rau lub taub hau txiav, zam cov teeb meem xws li cov kab tsis sib xws thiab burrs ntawm ntug los ntawm kev co thaum lub sijhawm txiav, ua kom ntseeg tau tias qhov du thiab zoo ntawm cov kab txiav, thiab txhim kho qhov zoo ntawm cov khoom FPC.
Kev ruaj khov thiab hnav tsis kam
Thaum lub sijhawm ua haujlwm ntev ntawm FPC laser txiav cov khoom siv, lub taub hau txiav txav mus los ntau zaus, uas ua rau muaj kev thov siab heev rau lub peev xwm thauj khoom thiab kev tiv thaiv hnav ntawm lub hauv paus. Granite muaj qhov nyuaj siab, nrog Mohs hardness ntawm 6 txog 7, thiab nws muaj lub zog compressive thiab kev tiv thaiv hnav. Nws cov qauv siab-rigidity tuaj yeem txhawb nqa ntau yam khoom ntawm cov khoom siv txiav. Txawm tias nyob rau hauv kev ua haujlwm txiav zaus siab, nws tsis yooj yim rau deformation lossis hnav. Piv nrog rau qee cov ntaub ntawv hauv paus uas yooj yim hnav, granite platforms txo qhov teeb meem ntawm kev poob qis precision los ntawm kev hnav, ntev lub neej kev pabcuam ntawm cov khoom siv, thiab txo cov nqi txij nkawm thiab hloov pauv ntawm cov khoom siv.
Kev ruaj khov tshuaj zoo
Tej zaum yuav muaj qee yam tshuaj lom neeg nyob rau hauv FPC ib puag ncig tsim khoom, xws li cov tshuaj ntxuav thiab cov kua dej. Granite feem ntau yog tsim los ntawm cov zaub mov xws li quartz thiab feldspar. Nws muaj cov khoom siv tshuaj ruaj khov thiab tiv taus corrosion zoo heev, thiab nws tiv taus cov tshuaj lom neeg xws li acids thiab alkalis. Qhov no ua kom ntseeg tau tias lub platform granite yuav tsis raug puas tsuaj los ntawm kev puas tsuaj tshuaj lom neeg hauv cov chaw tsim khoom nyuaj, lav qhov ruaj khov thiab kev ntseeg siab ntev ntawm lub hauv paus thiab muab kev lees paub rau kev ua haujlwm tas mus li thiab ruaj khov ntawm FPC laser txiav khoom siv.
Cov khoom siv txiav laser FPC xaiv lub platform granite ua lub hauv paus vim nws muaj kev ua tau zoo heev hauv ntau yam xws li kev ruaj khov thermal, kev tiv thaiv kev co, kev ruaj khov thiab kev hnav tsis kam, nrog rau kev ruaj khov tshuaj lom neeg. Cov yam ntxwv no ua haujlwm ua ke los txhim kho qhov tseeb ntawm kev txiav thiab cov khoom zoo, txuas lub neej ua haujlwm ntawm cov khoom siv, txo cov nqi tag nrho, thiab txhawb nqa kev txhim kho zoo ntawm kev lag luam tsim khoom FPC.
