Kev tshuaj xyuas kom meej txog qhov zoo thiab qhov txwv ntawm granite siv rau hauv cov khoom siv txheej.

Hauv kev siv cov khoom siv pleev xim, granite tau dhau los ua cov khoom siv xaiv tau zoo vim nws cov yam ntxwv tshwj xeeb. Txawm li cas los xij, nws tsis zoo tag nrho. Cov hauv qab no yuav tshuaj xyuas tag nrho cov txiaj ntsig thiab qhov tsis zoo ntawm granite hauv cov khoom siv pleev xim, muab cov ntaub ntawv qhia meej rau cov kws kho mob.
I. Cov txiaj ntsig tseem ceeb ntawm granite hauv kev ua yeeb yam khoom siv txheej
1. Kev ruaj khov zoo heev
Granite muaj qhov ceev thiab cov qauv ntom ntom, uas tuaj yeem tiv taus kev co thiab kev cuam tshuam sab nraud. Thaum lub sijhawm ua haujlwm ntawm cov khoom siv txheej, nws tuaj yeem tswj tau qhov ruaj khov ntawm cov khoom siv, zam cov teeb meem xws li kev txau tsis sib xws thiab cov txheej tuab tsis sib xws los ntawm kev co, thiab xyuas kom meej qhov tseeb thiab zoo ntawm cov txheej txheem tso saib.
2. Kev tiv thaiv xeb zoo heev
Granite feem ntau yog ua los ntawm cov zaub mov xws li quartz thiab feldspar. Nws muaj cov khoom siv tshuaj ruaj khov thiab muaj zog tiv taus cov tshuaj xws li acids thiab alkalis. Thaum lub sijhawm txheej txheem txheej, nws yog qhov tsis zam kom kov yeej ntau yam tshuaj lom neeg xws li xim thiab cov kuab tshuaj. Lub hauv paus granite tuaj yeem siv tau ntev yam tsis muaj xeb, ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua thiab txo cov nqi txij nkawm.
3. Qhov chaw siab precision
Los ntawm cov txheej txheem ua tiav siab heev, granite tuaj yeem raug sib tsoo thiab txhuam kom tiaj tus thiab du. Qhov chaw siab no tuaj yeem muab cov ntaub ntawv qhia txog kev teeb tsa kom raug rau cov khoom siv txheej, ua kom ntseeg tau tias qhov chaw sib piv ntawm cov khoom siv thiab ua kom zoo dua cov nyhuv txheej.
4. Muaj zog thermal stability
Tus coefficient ntawm thermal expansion ntawm granite yog qis heev. Nyob rau hauv ib puag ncig nrog loj kub variations, nws cov kev hloov pauv yog negligible. Qhov no feature ua rau cov zaub txheej khoom siv kom tswj tau lub xeev ua haujlwm ruaj khov nyob rau hauv ntau yam kub mob, thiab lub txheej raug yuav tsis raug cuam tshuam los ntawm thermal expansion thiab contraction.

II. Cov Kev Txwv ntawm Granite hauv Daim Ntawv Thov Cov Khoom Siv Txheej Txheem Zaub
1. Nws hnyav heev
Granite muaj qhov ceev ceev, uas ua rau qhov hnyav ntawm cov khoom siv nce ntxiv. Qhov no tsis yog tsuas yog ua rau muaj teeb meem ntawm kev thauj mus los thiab kev teeb tsa cov khoom siv, ua rau tus nqi thauj mus los nce ntxiv, tab sis kuj tseem yuav ua rau muaj qhov yuav tsum tau ua kom muaj peev xwm thauj khoom ntawm thaj chaw ua yeeb yam siab dua. Yog tias thaj chaw ntawm qhov chaw ua yeeb yam tsis tuaj yeem nqa tau, kev kho kom ruaj khov ntxiv kuj tseem xav tau.
2. Tus nqi siab heev
Txij li ntawm kev khawb av, kev ua tiav mus rau kev thauj mus los, tus nqi ntawm granite yog qhov siab heev. Tshwj xeeb tshaj yog cov khoom granite uas tau dhau los ua cov txheej txheem siab dua kuj kim dua. Rau cov lag luam lossis cov haujlwm uas muaj peev nyiaj tsawg, nws yuav ua rau muaj kev nyuaj siab ntau.
3. Nws nyuaj rau ua tiav
Granite yog ib yam khoom siv uas tawv heev. Thaum ua cov txheej txheem thib ob xws li kev khawb thiab kev txiav, yuav tsum muaj cov khoom siv thiab cov cuab yeej tshaj lij, ua rau lub voj voog ua haujlwm ntev thiab cov nqi ua haujlwm siab. Ntxiv mus, cov teeb meem xws li kev tawg thiab tawg yuav tshwm sim thaum lub sijhawm ua, uas yuav cuam tshuam rau qhov zoo ntawm kev ua thiab cov txiaj ntsig ntawm cov khoom tiav.
4. Kev nyuaj kho
Thaum cov granite saum npoo pom tias muaj kev puas tsuaj, khawb, lossis puas lawm, kev kho yuav nyuaj heev. Kev puas tsuaj me me tuaj yeem kho tau los ntawm kev sib tsoo thiab txhuam, tab sis yog tias qhov puas tsuaj loj heev, feem ntau yuav tsum tau hloov cov khoom, ua rau cov nqi kho thiab lub sijhawm kim heev.

Kev nkag siab txog qhov zoo thiab qhov tsis zoo ntawm granite hauv cov khoom siv txheej txheem tso saib tuaj yeem pab cov tuam txhab ua qhov kev xaiv tsim nyog raws li lawv tus kheej xav tau thiab qhov xwm txheej tiag tiag. Txawm hais tias nrhiav kev ua kom raug thiab ruaj khov lossis xav txog tus nqi thiab kev yooj yim txij nkawm, tsuas yog tom qab ntsuas qhov zoo thiab qhov tsis zoo ntawm cov khoom siv tuaj yeem ua tiav nws qhov ua tau zoo tshaj plaws thiab qhov zoo tshaj plaws ntawm kev txheej txheem tso saib.
