Kev Siv Granite Hauv Cov Khoom Siv Kuaj Xyuas Optical High-Precision.

 

Granite tau ntev los lawm rau nws cov khoom zoo heev, ua rau nws yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv engineering. Ib qho ntawm cov khoom siv tseem ceeb tshaj plaws ntawm granite yog nyob rau hauv thaj chaw ntawm cov khoom siv kuaj pom kev zoo. Granite cov khoom tshwj xeeb, xws li nws qhov ruaj khov, rigidity, thiab qis thermal expansion, pab nws ua tau zoo hauv thaj chaw tshwj xeeb no.

Cov khoom siv kuaj pom kev zoo siab xav tau lub platform ruaj khov kom ntseeg tau tias qhov ntsuas raug thiab cov txiaj ntsig txhim khu kev qha. Granite muab qhov kev ruaj khov no los ntawm kev muaj cov qauv ntom ntom, sib xws uas txo qis kev co thiab kev cuam tshuam sab nraud. Qhov no tseem ceeb heev hauv kev kuaj pom kev, qhov twg txawm tias qhov kev txav me me tuaj yeem ua rau muaj qhov yuam kev loj hauv kev ntsuas. Granite qhov tsis muaj zog kuj txhais tau tias nws tsis teb rau cov yam ntxwv ib puag ncig, kom ntseeg tau tias cov khoom siv tsis cuam tshuam los ntawm cov av noo lossis qhov kub thiab txias.

Tsis tas li ntawd xwb, granite tus coefficient qis ntawm thermal expansion yog ib qho tseem ceeb hauv cov ntawv thov siab. Thaum qhov kub hloov pauv, cov ntaub ntawv nthuav dav lossis cog lus, uas tuaj yeem ua rau tsis sib haum xeeb hauv cov kab ke optical. Granite tus coefficient qis heev ntawm thermal expansion ua kom ntseeg tau tias cov khoom siv optical tseem sib phim zoo, txhim kho qhov tseeb ntawm cov khoom siv sim.

Ntxiv rau nws cov khoom siv lub cev, granite yooj yim rau kev siv tshuab thiab ua tiav, uas tso cai rau nws siv los tsim cov qauv tsim thiab kev teeb tsa nyuaj uas xav tau rau cov khoom siv kuaj pom kev zoo heev. Lub peev xwm los tsim cov chaw tiaj tiaj siab yog qhov tseem ceeb rau cov khoom siv kho qhov muag, thiab granite ua tau zoo heev hauv qhov no.

Hauv kev xaus, kev siv granite hauv cov khoom siv kuaj pom kev zoo qhia tau tias nws cov khoom siv zoo dua. Nws qhov ruaj khov, kev nthuav dav thermal tsawg, thiab kev siv tshuab ua rau nws yog qhov kev xaiv tseem ceeb rau cov tuam txhab tsim khoom uas tab tom nrhiav kev tsim cov kev daws teeb meem kuaj pom kev zoo thiab raug. Raws li thev naus laus zis txuas ntxiv mus, lub luag haujlwm ntawm granite hauv daim teb no yuav txuas ntxiv mus, ua kom nws txoj haujlwm ruaj khov ua cov khoom siv tseem ceeb rau cov ntawv thov siab.
