Nyob rau hauv kev siv ntev ntawm semiconductor cov cuab yeej siv, cov teeb meem dab tsi yuav tshwm sim hauv granite Cheebtsam?

Granite yog siv dav hauv kev lag luam ib nrab ntawm lawv cov khoom lag luam zoo heev xws li kev nthuav dav ruaj khov, thiab qhov tseeb. Txawm li cas los xij, nyob rau hauv kev siv sijhawm ntev ntawm semiconductor, tej zaum yuav muaj qee yam teeb meem uas tshwm sim hauv granite. Nov yog qee qhov kev cov nyom uas yuav tshwm sim:

1. Hnav thiab kua muag

Ib qho teeb meem tshwm sim ntau tshaj plaws hauv cov khoom siv granite yog hnav thiab kua muag, uas tshwm sim vim muaj kev siv tas mus li. Lub sijhawm dhau los, cov chaw ntawm cov khoom lag luam granite yuav dhau los ua cov khawb lossis tawg, uas tuaj yeem cuam tshuam lawv qhov tseeb. Txawm li cas los xij, qhov teeb meem no tuaj yeem raug txo qis los ntawm kev khaws cov khoom huv thiab tswj nws tsis tu ncua.

2. Thermal expansion

Cov Cheebtsam Granite muaj qhov tsis tshua muaj cua sov heev nthuav tawm cov coefficient, uas txhais tau tias lawv tsis tshua nthuav lossis cog lus thaum raug hloov pauv qhov kub. Txawm li cas los xij, lub sijhawm dhau sijhawm, cov kev hloov pauv kub rov qab tuaj yeem ua rau qee qhov nthuav dav, ua rau txo qis dua hauv qhov tseeb. Txhawm rau tiv thaiv qhov no, nws yog ib qho tseem ceeb kom ntsuas kub ntawm cov khoom siv uas nyob ruaj khov li sai tau.

3. Kev nqus dej noo

Granite yog cov khoom siv ntxeem tau, thiab xws li, nws muaj peev xwm nqus ya raws. Yog hais tias cov granite tivthaiv tsis yog kaw zoo thiab muaj kev tiv thaiv, qhov no tuaj yeem ua rau kev nthuav dav thiab tawg tag sijhawm. Yog li ntawd, nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom sib xyaw granite yog muab khi rau cov dej noo kom tiv thaiv ib qho kev puas tsuaj los ntawm kev puas tsuaj.

4. Tshuaj Corrosion

Lwm qhov teeb meem uas yuav tshwm sim thaum siv cov khoom siv granite yog tshuaj lom neeg corrosion. Qee yam tshuaj lom neeg, xws li cov kua qaub thiab alkalis, tuaj yeem corrode saum npoo ntawm granite. Txhawm rau tiv thaiv qhov no, nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom siv granite muaj kev tiv thaiv los ntawm cov tshuaj tsim nyog los yog siv cov txheej txheem.

Hauv kev sib tw, thaum muaj tej yam kev cov nyom uas yuav tshwm sim thaum siv cov cuab yeej siv granite, kev saib xyuas zoo thiab saib xyuas tuaj yeem pab txo cov teeb meem no. Los ntawm kev ua kom cov khoom siv tsis tu ncua, ntxuav kom huv, thiab tiv thaiv los ntawm cov kev phom sij tuaj yeem txuas ntxiv tau txuas ntxiv thiab muaj kev ua haujlwm siab rau xyoo tom ntej.
