Hauv lub ntiaj teb uas muaj kev pheej hmoo siab ntawm kev ntsuas qhov tseeb thiab kev tswj xyuas zoo, lub hauv paus ntawm txhua qhov kev ntsuas qhov tseeb yog cov cuab yeej siv los ua piv txwv. Tau ntau xyoo, cov granite zoo tau yog tus huab tais tsis muaj kev sib cav ntawm cov chaw kuaj metrology thiab cov plag tsev tsim khoom. Nws qhov kev ruaj khov ntuj, qhov nyuaj, thiab kev tiv thaiv corrosion ua rau nws yog qhov kev xaiv tsis raug rau cov phaj nto, cov phaj kaum sab xis, thiab cov khoom sib piv meej. Txawm li cas los xij, nyob rau xyoo tas los no, cov khoom siv ceramics siab heev tau tshwm sim ua tus neeg sib tw loj heev, cog lus tias yuav ua tau zoo dua hauv cov chaw xav tau tshwj xeeb.
Rau cov thawj coj hauv chav kuaj, cov kws ua haujlwm zoo, thiab cov kws tshaj lij kev yuav khoom, qhov kev xaiv ntawm ob yam khoom no tsis yog hais txog tus nqi xwb - nws yog hais txog kev sib phim cov khoom siv lub cev rau koj qhov chaw ua haujlwm tshwj xeeb. Koj puas yuav tsum ua raws li kev ntseeg siab ntawm granite, lossis nqis peev rau qhov kev ua kom zoo dua ntawm ceramic? Cia peb kawm txog kev sib piv kom pab koj txiav txim siab seb cov khoom twg zoo tshaj plaws rau koj chav kuaj.
Kev Txhim Kho ntawm Granite uas Nyob Mus Ib Txhis
Cov cuab yeej ntsuas granite yog ua los ntawm cov pob zeb igneous ntuj, feem ntau yog granite dub zoo lossis gabbro. Tom qab raug rho tawm, lub pob zeb yuav dhau los ntawm cov txheej txheem laus ntuj uas tuaj yeem siv sijhawm ntau xyoo los txo cov kev ntxhov siab sab hauv, ua raws li kev sib tsoo raug thiab kev sib tsoo tes kom ua tiav qhov tiaj tiaj.
Qhov zoo tshaj plaws ntawm granite yog nws qhov kev ruaj khov thermal zoo heev. Granite muaj qhov coefficient qis heev ntawm thermal expansion (feem ntau nyob ib puag ncig 4.6 × 10⁻⁶ / °C). Qhov no txhais tau tias qhov kev hloov pauv ib txwm muaj hauv chav tsev kub yuav ua rau muaj kev hloov pauv me me, ua kom koj cov kev ntsuas tseem sib xws thoob plaws hnub. Ntxiv mus, vim nws yog pob zeb ntuj, nws tsis yog magnetic, tsis conductive, thiab tsis muaj xeb kiag li. Yog tias qhov chaw granite raug khawb lossis lwj los ntawm cov cuab yeej poob, cov khoom siv feem ntau tsim qhov kev nyuaj siab me me es tsis txhob tsa lub burr, uas txhais tau tias qhov tiaj tiaj ntawm lub dav hlau siv tsis tshua muaj kev cuam tshuam los ntawm qhov xwm txheej me me.
Granite kuj tseem khov kho heev thiab muaj kev co zoo heev. Qhov no ua rau nws yog lub hauv paus zoo tshaj plaws rau cov Tshuab Ntsuas Coordinate (CMMs) hnyav thiab cov khoom siv kho qhov muag rhiab heev uas kev co sab nraud tuaj yeem ua rau cov txiaj ntsig tsis zoo. Rau kev siv hauv chav kuaj dav dav thiab chaw ua haujlwm ruaj khov, cov granite qib siab (xws li DIN 876 Qib 0 lossis 00) tseem yog tus qauv kub rau kev ua haujlwm raug nqi.
Kev Sawv Ntxov ntawm Cov Khoom Siv Ua Los Ntawm Tej Hub
Cov khoom siv ua los ntawm cov khoom siv thev naus laus zis, feem ntau yog ua los ntawm cov ntaub ntawv xws li zirconia (ZrO₂) lossis alumina (Al₂O₃), raug tsim ua hauv chav kuaj es tsis yog rho tawm hauv ntiaj teb. Cov txheej txheem tsim khoom no tso cai rau cov kws tshawb fawb los kho cov khoom ntawm cov khoom kom ua tau zoo heev.
Qhov tshwj xeeb ntawm cov cuab yeej ntsuas ceramic yog lawv lub zog thiab kev tiv taus kev hnav. Cov khoom ua los ntawm ceramics nyuaj dua li granite thiab txawm tias cov hlau tawv. Hauv cov chaw ua haujlwm siab uas cov gauge blocks lossis cov phaj nto raug tuav ntau txhiab zaus hauv ib hnub, cov cuab yeej ceramic tuaj yeem kav ntev dua li kaum npaug ntawm lawv cov hlau thiab qhia tau tias muaj kev tiv taus kev puas tsuaj zoo dua li cov granite txheem.
Lwm qhov zoo ntawm cov khoom siv ceramic yog nws cov tshuaj lom neeg tsis muaj zog. Txawm hais tias granite tiv taus feem ntau cov kua qaub, cov khoom siv ceramic yuav luag tsis nkag mus rau txhua yam dej txias, roj, alkalis, thiab cov tshuaj lom neeg corrosive uas pom muaj nyob rau hauv kev tsim khoom niaj hnub no. Tsis tas li ntawd, cov khoom siv ceramic tsis muaj qhov. Tsis zoo li granite, uas tuaj yeem nqus tau cov dej noo lossis roj me me yog tias tsis khaws cia kom huv, qhov chaw ceramic tuaj yeem so tam sim ntawd yam tsis ntshai ntawm kev pleev xim lossis kev nqus.
Tej zaum qhov xav tsis thoob tshaj plaws ntawm cov khoom siv niaj hnub no yog lawv qhov kev tawg ua tej daim tawv. Txawm hais tias cov tiam neeg qub ntawm cov khoom siv ceramics tau tawg yooj yim, cov khoom siv ceramics niaj hnub no uas muaj zirconia tiv taus kev tawg thiab tawg. Yog tias lub thaiv ceramic gauge raug poob, nws yuav tsis tawg ntau dua li ib tus neeg xav tau, ua rau nws muaj zog heev rau kev siv hauv pem teb.
Kev Sib Tw Ua Tau Zoo Tshaj Plaws
Thaum txiav txim siab ntawm ob qho no, nws yuav pab tau saib seb lawv ua tau li cas hauv cov xwm txheej tshwj xeeb.
Kev Ua Haujlwm Kub: Granite yeej ntawm qhov tsis muaj zog kub ntshiab. Nws cov thermal conductivity qis txhais tau tias nws siv sijhawm ntev kom sov lossis txias, ua haujlwm ua lub thermal buffer. Txawm li cas los xij, qee cov ceramics siab heev tau tsim los kom muaj cov coefficient thermal expansion ze heev rau hlau. Qhov no ua rau cov ceramic gauge blocks zoo heev rau kev ntsuas cov hlau hauv cov chaw uas qhov kub yuav poob me ntsis ntawm tus qauv 20 ° C, vim tias cov ceramic thiab cov hlau yuav nthuav dav thiab cog lus ntawm cov nqi zoo sib xws.
Qhov Hnyav thiab Kev Tuav: Feem ntau cov khoom ua los ntawm cov av nplaum muaj qhov ceev tsawg dua li cov granite. Rau cov phaj loj lossis cov choj loj CMM, cov qauv av nplaum tuaj yeem sib dua thaum tseem tswj tau tib theem ntawm kev ruaj khov. Qhov hnyav txo qis no tso cai rau kev nrawm dua thiab qeeb dua hauv cov ntawv thov scanning tsis siv neeg, ua rau kev tshuaj xyuas ntau ntxiv yam tsis muaj kev txi qhov tseeb.
Kev Txij Nkawm thiab Kev Siv Tau Ntev: Granite yuav luag tsis tas yuav tsum tau kho dua li tsuas yog ua kom nws huv thiab npog nws thaum tsis siv. Cov khoom siv ceramics ua qhov no ntxiv mus los ntawm kev yooj yim dua los ntxuav vim lawv qhov chaw tsis muaj qhov. Txawm li cas los xij, kev nqis peev thawj zaug rau cov cuab yeej ceramic feem ntau yog siab dua vim yog cov txheej txheem sintering thiab kev sib tsoo uas xav tau los tsim lawv.
Ua Qhov Kev Xaiv Zoo Rau Koj Lub Chaw Kuaj Mob
Yog li, koj yuav tsum xaiv cov khoom siv twg? Cov lus teb nyob ntawm koj daim ntawv thov thiab ib puag ncig.
Yog tias koj tab tom teeb tsa lub chaw kuaj xyuas tus qauv, chav ntsuas, lossis chaw ua haujlwm ruaj khov, siv Granite. Yog tias koj qhov kev xav tau tseem ceeb yog qhov chaw loj thiab ruaj khov rau kev ntsuas qhov tseeb dav dav, granite muaj qhov sib npaug zoo tshaj plaws ntawm kev ua tau zoo thiab tus nqi. Nws cov kev co ntuj tsim thiab cov ntaub ntawv pov thawj ua rau nws yog qhov kev xaiv nyab xeeb thiab txhim khu kev qha rau 90% ntawm cov ntawv thov metrology.
Hloov mus siv Ceramics yog tias koj lub chaw kuaj mob ua haujlwm nyob rau hauv ib puag ncig hnyav. Yog tias koj cov cuab yeej yuav raug rau cov dej txias hnyav, roj, lossis qhov kub hloov pauv ntau zaus, ceramic yog qhov kev xaiv zoo tshaj plaws. Nws tseem yog cov khoom siv zoo tshaj plaws rau cov ntawv thov hnav siab, xws li cov gauge blocks siv rau hauv cov kab ntau lawm, lossis rau cov khoom txav mus los ntawm CMMs ceev ceev qhov twg qhov hnyav tsawg thiab qhov ruaj khov siab yog qhov tseem ceeb rau qhov tseeb dynamic.
Thaum kawg, ob qho khoom siv sawv cev rau qhov siab tshaj plaws ntawm kev tsim kho qhov tseeb. Granite tseem yog lub hauv paus ruaj khov ntawm lub ntiaj teb metrology, thaum ceramics muab kev daws teeb meem siab rau cov teeb meem nyuaj tshaj plaws. Los ntawm kev nkag siab txog lub zog ntawm txhua yam, koj tuaj yeem ua kom koj lub chaw kuaj mob muaj cov cuab yeej zoo los xa cov txiaj ntsig raug, txhim khu kev qha, thiab rov ua dua.
