Lub thermal stability ntawm granite hauv cov khoom siv ntsuas precision yog dab tsi?

Granite yog ib yam khoom siv uas siv ntau hauv cov khoom siv ntsuas qhov tseeb vim nws qhov kev ruaj khov thermal zoo heev. Qhov kev ruaj khov thermal ntawm granite hais txog nws lub peev xwm los tswj nws qhov ruaj khov ntawm qhov ntev thiab tiv taus kev hloov pauv hauv qab qhov kub thiab txias. Qhov no yog ib qho tseem ceeb hauv cov khoom siv ntsuas qhov tseeb, vim tias txhua qhov kev hloov pauv ntawm qhov ntev ntawm cov khoom siv tuaj yeem ua rau kev ntsuas tsis raug thiab txo qhov zoo.

Granite muaj kev ruaj khov thermal zoo vim nws cov coefficient qis ntawm thermal expansion. Qhov no txhais tau tias nws nthuav dav thiab cog lus tsawg kawg nkaus vim muaj kev hloov pauv kub, ua kom ntseeg tau tias qhov loj ntawm lub cuab yeej ntsuas tseem sib xws. Tsis tas li ntawd, granite muaj kev tiv taus cua sov zoo heev thiab tuaj yeem tiv taus qhov kub siab yam tsis muaj kev sib txhuam lossis kev hloov pauv.

Qhov ruaj khov ntawm granite yog qhov tseem ceeb rau cov khoom siv ntsuas qhov tseeb xws li cov tshuab ntsuas sib koom ua ke (CMMs) thiab cov theem. CMMs vam khom qhov ruaj khov ntawm lawv cov hauv paus granite kom ntseeg tau tias muaj kev ntsuas raug thiab rov ua dua. Txhua qhov kev nthuav dav lossis kev cog lus ntawm granite tuaj yeem ua rau muaj qhov yuam kev ntsuas thiab cuam tshuam rau kev ntseeg siab ntawm cov khoom siv.

Cov platforms siv ua qhov chaw siv los ua qhov chaw soj ntsuam rau kev tshuaj xyuas cov khoom ua haujlwm kuj tau txais txiaj ntsig los ntawm granite lub thermal stability. Cov khoom siv tiv taus qhov kub thiab txias ua rau lub platform tswj tau nws qhov tiaj tus thiab raug, muab lub hauv paus txhim khu kev qha rau kev ntsuas meej.

Ntxiv rau qhov ruaj khov ntawm thermal, granite muaj lwm yam khoom uas xav tau rau cov khoom siv ntsuas qhov tseeb, suav nrog kev ruaj khov siab, porosity tsawg thiab tsawg kawg deformation hauv qab load. Cov yam ntxwv no ua rau qhov tseeb thiab kev ntseeg siab ntawm lub cuab yeej zoo dua.

Zuag qhia tag nrho, qhov ruaj khov thermal ntawm granite hauv cov khoom siv ntsuas qhov tseeb yog qhov tseem ceeb hauv kev ua kom ntseeg tau qhov tseeb thiab kev sib xws. Los ntawm kev siv cov ntaub ntawv nrog qhov nthuav dav thermal tsawg kawg nkaus thiab kev tiv thaiv cua sov zoo heev, cov tuam ntxhab tuaj yeem vam khom qhov ruaj khov ntawm lawv cov khoom siv hla ntau qhov kub thiab txias, thaum kawg txhim kho kev tswj hwm zoo thiab qhov tseeb ntawm cov txheej txheem ntsuas.
