Cov hom granite sib txawv siv rau hauv kev tsim cov khoom siv kho tshuab ntawm cov cuab yeej ntsuas yog dab tsi?

Granite siv dav hauv kev tsim cov khoom siv kho tshuab rau cov cuab yeej ntsuas vim nws ruaj khov, muaj zog thiab tiv taus kev hnav thiab rhuav. Muaj ntau hom granite uas tau xaiv tshwj xeeb rau lawv cov yam ntxwv tshwj xeeb thiab haum rau ntau yam kev siv hauv kev tsim cov cuab yeej precision.

Hauv cov ntsiab lus no, ib hom granite uas siv ntau tshaj plaws hu ua "granite" (huā gāng shí), uas txhais ua granite hauv lus Askiv. Hom granite no muaj nqis rau nws cov qauv zoo, uas tso cai rau kev ua tiav thiab ua tiav. Nws qhov ceev thiab porosity qis ua rau nws zoo tagnrho rau cov khoom uas xav tau kev ruaj khov thiab kev tiv thaiv corrosion.

Lwm hom granite siv rau kev ua cov khoom siv kho tshuab ntawm cov cuab yeej ntsuas yog granite dub. Paub txog nws cov qauv sib xws thiab xim tsaus, hom no muaj qhov zoo nkauj thiab kev ruaj khov zoo heev thiab kev co-damping. Granite dub feem ntau siv rau hauv lub hauv paus thiab cov qauv txhawb nqa ntawm cov cuab yeej precision kom ntseeg tau tias qhov ntsuas raug thiab txhim khu kev qha.

Ntxiv rau cov hom no, muaj cov granite tshwj xeeb uas tsim los ua kom tau raws li cov kev xav tau tshwj xeeb ntawm kev tsim cov cuab yeej ntsuas. Piv txwv li, qee cov granites muaj cov coefficient thermal expansion qis thiab tsim nyog rau kev siv hauv cov chaw uas muaj qhov kub thiab txias hloov pauv. Lwm tus yuav muaj cov yam ntxwv damping zoo dua los txo qhov cuam tshuam ntawm kev co sab nraud rau qhov tseeb ntawm cov cuab yeej.

Kev xaiv hom granite zoo rau kev tsim cov khoom siv kho tshuab hauv cov cuab yeej ntsuas yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov cuab yeej ua haujlwm tau zoo thiab kav ntev. Cov chaw tsim khoom ua tib zoo xav txog cov yam xws li daim ntawv thov, cov xwm txheej ib puag ncig thiab cov kev cai raug thaum xaiv hom granite siv.

Hauv kev xaus lus, granite, suav nrog "granite" thiab granite dub, ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv kho tshuab ntawm cov cuab yeej ntsuas. Nws cov yam ntxwv tshwj xeeb ua rau nws yog cov khoom siv zoo tshaj plaws rau kev ua kom raug, ruaj khov thiab ntseeg tau ntawm cov cuab yeej precision hauv ntau yam kev siv hauv kev lag luam thiab kev tshawb fawb.
