Hauv kev tsim khoom siv ultra-precision, kev sib tsoo thiab polishing ntawm granite nto phaj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov tiaj tiaj ntawm qhov chaw, gloss, thiab qhov tseeb tag nrho. Txawm hais tias granite yog ib qho ntawm cov khoom siv ntuj tsim uas nyuaj tshaj plaws thiab ruaj khov tshaj plaws, kev ua tiav qhov micrometer-level precision tseem nyob ntawm kev xaiv zoo thiab kev siv cov kua polishing thiab cov neeg sawv cev polishing kom raug.
Thaum lub sijhawm sib tsoo, cov kua thiab cov neeg sawv cev no tsis yog tsuas yog cuam tshuam rau cov nqi tshem tawm cov khoom siv xwb tab sis kuj cuam tshuam rau qhov tiav ntawm qhov chaw thiab kev ruaj khov mus sij hawm ntev ntawm lub platform granite. Yog li ntawd, kev xaiv hom thiab cov mis kom raug yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws thiab txuas ntxiv lub neej ntawm cov khoom granite precision.
Hauv cov ntawv thov kev tshaj lij, cov kua thiab cov neeg sawv cev siv rau kev sib tsoo granite platform feem ntau muab faib ua plaub pawg ua haujlwm: cov tshuaj ntxuav, cov khoom siv abrasives, cov neeg sawv cev polishing, thiab cov sealants.
Cov tshuaj ntxuav feem ntau yog siv los tshem tawm cov kuab paug thiab cov khoom seem ntawm qhov chaw granite—xws li roj, oxide, lossis hmoov av me me—ua ntej thiab tom qab sib tsoo. Cov tshuaj ntxuav feem ntau suav nrog cov tshuaj ntxuav pH nruab nrab, cov tshuaj uas muaj kua qaub me ntsis, lossis cov tshuaj ntxuav alkaline. Thaum siv cov tshuaj ntxuav tshuaj, cov neeg ua haujlwm yuav tsum tswj kev sib xyaw thiab lub sijhawm raug tshuaj kom tiv thaiv kev khawb tshuaj lossis kev ua kom qhov chaw granite tsaus.
Cov khoom siv txhuam ua lub hauv paus tseem ceeb rau kev tshem tawm cov khoom siv. Cov noob txhuam txiav thiab ua kom tiaj tus ntawm granite kom tshem tawm cov qhov tsis zoo me me, khawb, thiab tsis sib luag. Cov khoom siv txhuam siv dav tshaj plaws yog alumina, silicon carbide, thiab cov khoom sib xyaw silica uas muaj purity siab. Kev xaiv hom txhuam, qhov loj ntawm cov khoom me me, thiab kev sib xyaw ua ke nyob ntawm qhov nyuaj ntawm granite thiab qhov tseeb ntawm qhov chaw xav tau. Rau kev ua tiav zoo, cov khoom txhuam nrog cov khoom me me hauv qab micron yog siv los ua kom tiav cov chaw tiaj tus hauv 1-2 µm kev kam rau siab.
Cov tshuaj txhuam hniav raug siv tom qab sib tsoo kom txhim kho qhov chaw du thiab ci ntsa iab. Hauv theem no, lub hom phiaj tsis yog tshem tawm cov khoom siv tab sis ua kom zoo nkauj ntawm cov qauv me me ntawm qhov chaw. Cov qauv siab heev uas ua los ntawm polyurethane, acrylic compounds, thiab chromium oxide feem ntau siv los tsim cov tiav zoo li daim iav. Qhov sib npaug ntawm qhov siab, qhov ceev, thiab cov tshuaj sib xyaw yog qhov tseem ceeb rau kev ua tiav qhov ci ntsa iab yam tsis muaj kev cuam tshuam qhov tseeb.
Thaum kawg, cov tshuaj sealant raug siv ua ib txheej tiv thaiv thaum polishing tiav. Granite nws tus kheej yog heev resistant rau corrosion thiab kub variation, tab sis kev siv ib tug tsim nyog sealant txhim kho resistant rau dej, roj, thiab hmoov av thaum tswj lub platform lub optical thiab mechanical stability. Cov kws tshaj lij manufacturers feem ntau siv polymer los yog wax-based sealants los xyuas kom meej tias muaj kev tiv thaiv mus sij hawm ntev, tshwj xeeb tshaj yog nyob rau hauv high-av noo los yog laboratory ib puag ncig.
Thaum ua granite sib tsoo thiab polishing, cov neeg teb xov tooj yuav tsum xyuas kom meej tias qhov kub thiab txias thiab av noo ib puag ncig - feem ntau 20 ± 1 ° C - kom tiv thaiv kev hloov pauv thermal. Siv dej huv lossis cov kua polishing nruab nrab kuj raug pom zoo kom tsis txhob muaj cov khoom tsis huv. Kev saib xyuas tsis tu ncua, suav nrog kev ntxuav thiab kev tshuaj xyuas lub phaj nto, pab khaws nws qhov tseeb thiab ntev nws lub neej kev pabcuam.
Xaus lus, kev ua tiav qhov tiav zoo kawg nkaus ntawm lub phaj granite precision nyob ntawm kev xaiv thiab kev siv cov kua polishing thiab cov neeg sawv cev. Txhua theem—txij li kev ntxuav mus rau kev kaw—yuav tsum muaj kev txawj ntse, kev saib xyuas kom meej, thiab kev tswj hwm cov txheej txheem nruj. Thaum ua tiav kom raug, qhov tshwm sim yog lub platform granite nrog qhov tiaj tiaj, du, thiab ruaj khov—ua kom muaj kev ua tau zoo rau kev ntsuas qhov tseeb thiab cov ntawv thov tsim khoom siab.
