Granite yog ib lub pob zeb ntuj uas siv dav hauv kev tsim cov khoom siv tshuab rau kev lag luam tsheb thiab aerospace. Txawm hais tias cov khoom siv no suav tias yog cov khoom siv ruaj khov thiab txhim khu kev qha, nws tseem tuaj yeem muaj qee qhov tsis zoo uas tuaj yeem cuam tshuam rau nws qhov zoo thiab kev ua tau zoo. Hauv tsab xov xwm no, peb yuav tham txog qee qhov tsis zoo uas tuaj yeem tshwm sim hauv cov khoom siv tshuab granite.
1. Qhov tsis zoo ntawm qhov chaw
Ib qho ntawm cov teeb meem pom tseeb tshaj plaws hauv cov khoom siv granite yog qhov tsis zoo ntawm qhov chaw. Cov teeb meem no tuaj yeem suav nrog cov khawb me me thiab cov teeb meem loj dua xws li tawg thiab chips. Cov teeb meem ntawm qhov chaw tuaj yeem tshwm sim thaum lub sijhawm tsim khoom lossis vim yog kev ntxhov siab thermal, uas tuaj yeem ua rau granite warp lossis deform. Cov teeb meem no tuaj yeem ua rau qhov tseeb thiab qhov tseeb ntawm lub tshuab, cuam tshuam rau nws txoj haujlwm.
2. Qhov porosity
Granite yog ib yam khoom uas muaj qhov me me, uas txhais tau tias nws muaj cov qhov me me lossis cov qhov uas tuaj yeem ntes cov dej noo thiab lwm yam kua dej. Qhov porosity yog ib qho teeb meem uas feem ntau tshwm sim hauv cov khoom siv granite, tshwj xeeb tshaj yog tias cov khoom tsis tau kaw lossis tiv thaiv kom zoo. Granite qhov porosity tuaj yeem nqus cov kua dej xws li roj, coolant, thiab roj, uas tuaj yeem ua rau xeb thiab lwm yam kev puas tsuaj. Qhov no tuaj yeem ua rau lub tshuab puas tsuaj ua ntej lub sijhawm, txo nws lub neej.
3. Cov Khoom Muaj Xws Li
Cov khoom uas muaj nyob hauv yog cov khoom txawv teb chaws uas tuaj yeem raug ntes rau hauv cov khoom siv granite thaum lub sijhawm tsim khoom. Cov khoom no tuaj yeem yog los ntawm huab cua, cov cuab yeej txiav, lossis cov dej txias uas siv thaum lub sijhawm tsim khoom. Cov khoom uas muaj nyob hauv tuaj yeem ua rau cov chaw tsis muaj zog hauv granite, ua rau nws yooj yim tawg lossis tawg. Qhov no tuaj yeem ua rau lub zog thiab kev ruaj khov ntawm lub tshuab tsis zoo.
4. Kev Hloov Xim
Granite yog ib lub pob zeb ntuj, thiab yog li ntawd, nws tuaj yeem muaj ntau yam xim thiab cov qauv sib txawv. Txawm hais tias cov kev hloov pauv no feem ntau suav hais tias yog ib qho zoo nkauj, qee zaum lawv tuaj yeem yog qhov tsis zoo yog tias lawv cuam tshuam rau kev ua haujlwm ntawm lub tshuab. Piv txwv li, yog tias ob daim granite siv rau ib qho tshuab, tab sis lawv muaj xim lossis cov qauv sib txawv, qhov no tuaj yeem cuam tshuam rau qhov tseeb lossis qhov tseeb ntawm qhov.
5. Qhov Loj thiab Cov Duab Sib Txawv
Lwm qhov tsis zoo ntawm cov khoom siv hauv tshuab granite yog qhov sib txawv ntawm qhov loj thiab cov duab. Qhov no tuaj yeem tshwm sim yog tias cov granite tsis raug txiav kom zoo lossis yog tias cov cuab yeej txiav tsis tau sib dhos kom zoo. Txawm tias qhov sib txawv me me ntawm qhov loj lossis cov duab tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hauv tshuab, vim tias lawv tuaj yeem ua rau tsis sib haum lossis qhov sib txawv uas tuaj yeem ua rau nws txoj haujlwm tsis zoo.
Xaus lus, thaum granite yog cov khoom siv ruaj khov thiab txhim khu kev qha rau cov khoom siv hauv kev lag luam tsheb thiab aerospace, nws tseem tuaj yeem muaj qee qhov tsis zoo uas tuaj yeem cuam tshuam rau nws qhov zoo thiab kev ua tau zoo. Cov tsis zoo no suav nrog qhov tsis zoo ntawm qhov chaw, porosity, inclusions, xim sib txawv, thiab qhov loj me thiab cov duab sib txawv. Los ntawm kev paub txog cov tsis zoo no thiab ua cov kauj ruam los tiv thaiv lawv, cov chaw tsim khoom tuaj yeem tsim cov khoom siv tshuab granite zoo uas ua tau raws li qhov xav tau ntawm cov lag luam no.
