Granite vs. cam khwb cia hlau thiab ntxhia Casting txaj: To taub Thermal Expansion Coefficients thiab lawv cuam tshuam rau lub tshuab cuab yeej raug
Thaum nws los txog rau kev tsim kho cov cuab yeej siv lub txaj, cov ntaub ntawv xws li granite, cam khwb cia hlau, thiab ntxhia casting feem ntau yog siv vim lawv cov khoom tshwj xeeb. Ib qho tseem ceeb uas yuav tsum tau xav txog hauv kev xaiv cov ntaub ntawv no yog lawv cov thermal expansion coefficient, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog qhov kub thiab txias. Qhov sib txawv ntawm thermal expansion coefficients ntawm cam khwb cia hlau thiab pob zeb hauv av casting txaj tuaj yeem cuam tshuam qhov tseeb ntawm cov cuab yeej siv tshuab hauv qhov chaw kub sib txawv.
Cam khwb cia hlau, ib txwm siv cov khoom siv hauv kev tsim kho tshuab, muaj cov thermal expansion coefficient. Qhov no txhais tau hais tias thaum kub hloov pauv, cam khwb cia hlau txaj yog qhov yooj yim rau kev nthuav dav thiab kev cog lus, uas ua rau muaj kev hloov pauv ntawm lub tshuab cuab yeej. Ntawm qhov tod tes, ntxhia casting, feem ntau tsim los ntawm cov ntaub ntawv xws li epoxy resin thiab granite aggregates, muaj qis thermal expansion coefficient piv rau cam khwb cia hlau. Cov yam ntxwv no tso cai rau cov pob zeb casting txaj kom pom qhov hloov pauv me me hauv kev teb rau qhov kub thiab txias.
Qhov cuam tshuam ntawm qhov sib txawv no ua qhov tseem ceeb hauv ib puag ncig uas tswj qhov kub thiab txias. Nyob rau hauv ib puag ncig kub, qhov siab dua thermal expansion coefficient ntawm cam khwb cia hlau tuaj yeem ua rau qhov tsis raug ntawm lub tshuab cuab yeej, cuam tshuam rau nws cov precision thiab kev ua haujlwm. Conversely, ntxhia casting txaj, nrog lawv qis thermal expansion coefficient, yog zoo dua nruab kom muaj tseeb nyob rau hauv xws li mob.
Nyob rau hauv sib piv, nyob rau hauv uas tsis muaj-kub ib puag ncig, qis thermal expansion coefficient ntawm ntxhia casting tej zaum yuav ua rau ib tug stiffer qauv piv rau cam khwb cia hlau, muaj feem xyuam rau lub tshuab cuab yeej dynamic teb thiab kev co damping yam ntxwv. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau cov tuam txhab thiab cov neeg siv kom paub txog kev txiav txim siab raws li qhov tshwj xeeb ntawm qhov kub thiab txias uas lub tshuab cuab yeej yuav ua haujlwm.
Hauv kev xaus, lub thermal expansion coefficient plays lub luag haujlwm tseem ceeb hauv kev xaiv cov khoom siv rau cov cuab yeej tshuab txaj. Thaum cam khwb cia hlau yog ib txwm xaiv, qhov qis thermal expansion coefficient ntawm ntxhia casting, feem ntau siv granite, muaj qhov zoo hauv kev tswj xyuas qhov tseeb hauv qhov kub thiab txias. Los ntawm kev xav txog cov xwm txheej no, cov tuam ntxhab thiab cov neeg siv khoom tuaj yeem ua kom zoo dua qhov kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov cuab yeej siv tshuab hauv ntau hom kev ua haujlwm.
