Granite Precision Apparatus yog ib yam khoom zoo heev uas siv rau hauv ntau yam lag luam xws li kev tsim kho, aerospace, thiab precision engineering. Nws yog ib lub pob zeb ntuj uas tsim los ntawm molten magma nyob rau hauv siab siab thiab kub. Txawm li cas los xij, txawm hais tias granite paub txog nws lub zog thiab kev ruaj khov, nws muaj qee qhov tsis zoo uas ua rau nws tsis haum rau kev sib dhos precision apparatus.
Ib qho ntawm cov teeb meem tseem ceeb ntawm granite yog nws qhov porosity. Granite yog ib lub pob zeb ntuj uas muaj cov qhov me me, uas yog tsim los ntawm nws cov txheej txheem tsim. Cov qhov no tuaj yeem ua rau muaj kev tawg lossis tawg ntawm qhov chaw ntawm granite, uas tuaj yeem cuam tshuam rau cov txheej txheem sib dhos ntawm cov khoom siv precision. Qhov no tuaj yeem ua rau cov khoom siv tsis raug thiab tsis txhim khu kev qha, thiab nws tuaj yeem cuam tshuam rau qhov zoo ntawm cov khoom kawg.
Lwm qhov teeb meem nrog granite yog nws qhov hnyav. Txawm hais tias qhov cwj pwm no tuaj yeem pab tau rau qee qhov kev siv, nws kuj tuaj yeem ua rau muaj qhov tsis zoo loj hauv qee kis. Piv txwv li, hauv kev lag luam aerospace, qhov twg qhov hnyav yog qhov tseem ceeb, kev siv granite hauv kev sib dhos precision apparatus tuaj yeem ua rau muaj kev thauj khoom ntxiv thiab tsis tsim nyog rau ntawm lub dav hlau, yog li ua rau kev siv roj ntau ntxiv thiab txo qhov ceev.
Ntxiv mus, granite kuj tseem tuaj yeem raug rau thermal expansion thiab contraction. Thaum lub sijhawm hloov pauv ntawm qhov kub thiab txias, granite tuaj yeem nthuav dav lossis contraction, uas tuaj yeem ua rau muaj kev cuam tshuam hauv kev sib dhos, cuam tshuam rau qhov tseeb thiab qhov tseeb ntawm lub cuab yeej.
Tsis tas li ntawd xwb, granite tsis tiv taus cov tshuaj lom neeg, thiab nws tuaj yeem lwj thaum raug rau cov kua qaub lossis cov tshuaj yooj yim heev. Qhov cwj pwm no ua rau nws tsis haum rau siv rau hauv ib puag ncig uas muaj tshuaj lom neeg ntau, xws li hauv chav kuaj lossis cov chaw ua tshuaj lom neeg.
Txawm hais tias muaj cov teeb meem no los xij, muaj cov kauj ruam uas tuaj yeem ua tau los txo lawv cov teebmeem. Piv txwv li, kev siv cov sealants tuaj yeem txo qhov porosity ntawm granite, yog li txo qhov muaj feem ntawm kev tawg hauv qab. Kev siv cov ntaub ntawv sib dua kuj tseem tuaj yeem txo qhov hnyav ntawm lub cuab yeej, thaum kev nthuav dav thermal tuaj yeem txo qis los ntawm kev siv cov txheej txheem tswj thermal kom zoo. Tsis tas li ntawd, kev siv cov tshuaj tiv thaiv tshuaj tuaj yeem tiv thaiv granite los ntawm cov tshuaj tiv thaiv.
Xaus lus, txawm hais tias granite yog ib yam khoom siv ruaj khov thiab siv tau ntev, nws muaj nws cov qhov tsis zoo uas tuaj yeem cuam tshuam rau qhov tseeb thiab qhov tseeb ntawm cov khoom siv precision. Txawm li cas los xij, nrog kev npaj, tsim qauv, thiab xaiv cov khoom siv kom zoo, cov qhov tsis zoo no tuaj yeem txo tau, thiab kev siv granite tuaj yeem muaj txiaj ntsig zoo rau ntau yam kev siv.
