Granite yog cov khoom siv nrov rau lub hauv paus tshuab hauv tsheb thiab aerospace kev lag luam vim nws qhov ruaj khov siab, hardness, thiab qis thermal expansion.Txawm li cas los xij, zoo li txhua yam khoom siv, granite tsis zoo tag nrho thiab tej zaum yuav muaj qee qhov tsis xws luag uas tuaj yeem cuam tshuam rau nws qhov zoo thiab kev ua tau zoo hauv qee yam kev siv.Hauv tsab xov xwm no, peb yuav tham txog qee qhov tsis xws luag ntawm granite tshuab hauv paus thiab yuav ua li cas zam lossis txo lawv.
1. Kev tawg
Cov kab nrib pleb yog qhov tsis zoo tshaj plaws hauv granite tshuab hauv paus.Kev tawg tuaj yeem tshwm sim vim ntau qhov laj thawj xws li kev ntxhov siab thermal, kev co, kev tuav tsis raug, lossis qhov tsis xws ntawm cov khoom siv raw.Kev tawg tuaj yeem cuam tshuam rau kev ruaj ntseg thiab qhov tseeb ntawm lub tshuab, thiab hauv qhov xwm txheej hnyav, tuaj yeem ua rau lub tshuab ua tsis tiav.Txhawm rau kom tsis txhob muaj kab nrib pleb, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov granite zoo, tsis txhob muaj kev ntxhov siab, thiab tuav lub tshuab nrog kev saib xyuas.
2. Nto roughness
Granite nto tuaj yeem ntxhib, uas tuaj yeem cuam tshuam kev ua haujlwm ntawm lub tshuab.Deg roughness tuaj yeem tshwm sim los ntawm qhov tsis xws ntawm cov khoom siv raw, polishing tsis raug, lossis hnav thiab tsim kua muag.Yuav kom tsis txhob nto roughness, granite nto yuav tsum tau polished kom zoo tag.Kev tu thiab tu tsis tu ncua tuaj yeem pab tiv thaiv qhov roughness.
3. Dimensional instability
Granite paub txog nws qhov ruaj khov thiab tsis tshua muaj thermal expansion, tab sis nws tsis muaj kev tiv thaiv rau qhov seem tsis ruaj khov.Dimensional instability tuaj yeem tshwm sim vim qhov hloov pauv ntawm qhov kub thiab av noo, uas tuaj yeem ua rau granite nthuav lossis cog lus.Dimensional instability tuaj yeem cuam tshuam qhov tseeb ntawm lub tshuab thiab ua rau cov khoom tsis raug.Txhawm rau kom tsis txhob muaj qhov tsis ruaj khov, nws yog ib qho tseem ceeb kom tswj tau qhov kub thiab txias ib puag ncig thiab siv cov granite zoo.
4. Cov impurities
Granite tuaj yeem muaj cov impurities xws li hlau, uas tuaj yeem cuam tshuam qhov zoo thiab kev ua haujlwm ntawm lub tshuab.Cov impurities tuaj yeem ua rau granite corrode, txo nws cov stability, los yog cuam tshuam rau nws cov khoom sib nqus.Txhawm rau kom tsis txhob muaj impurities, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov granite zoo thiab xyuas kom meej tias cov khoom siv raw tsis muaj impurities.
5. Txiav
Chiping yog lwm qhov tsis xws luag hauv granite tshuab hauv paus.Chiping tuaj yeem tshwm sim vim kev tuav tsis raug, kev co, lossis kev cuam tshuam.Chiping tuaj yeem cuam tshuam qhov ruaj khov thiab raug ntawm lub tshuab thiab ua rau lub tshuab ua tsis tiav.Txhawm rau kom tsis txhob chipping, nws yog ib qho tseem ceeb uas yuav tau tuav lub tshuab nrog kev saib xyuas thiab tsis txhob cuam tshuam los yog kev co.
Hauv kev xaus, granite tshuab hauv paus yog siv dav hauv tsheb thiab aerospace kev lag luam vim lawv qhov ruaj khov thiab tawv.Txawm li cas los xij, granite tsis zoo tag nrho thiab tej zaum yuav muaj qee qhov tsis xws luag tuaj yeem cuam tshuam rau nws qhov zoo thiab kev ua haujlwm.Los ntawm kev nkag siab txog cov kev tsis zoo no thiab kev tiv thaiv kev tiv thaiv, peb tuaj yeem xyuas kom meej tias lub hauv paus tshuab granite yog qhov zoo tshaj plaws thiab ua tau raws li qhov xav tau ntawm kev lag luam.
