Ua ntej, qhov zoo ntawm cov khoom siv granite precision
1. Muaj zog thiab tsis yooj yim hnav: Granite, ua ib lub pob zeb tawv ntuj, muaj zog thiab tsis yooj yim hnav. Qhov no ua rau cov khoom siv granite precision kom tswj tau qhov tseeb ntawm qhov chaw thiab ruaj khov thaum siv ntev, thiab tsis yooj yim hnav lossis khawb.
2. Tus coefficient qis ntawm thermal expansion: Tus coefficient ntawm thermal expansion ntawm granite yog qhov me me, yog li nws tseem tuaj yeem tswj tau qhov ruaj khov zoo hauv qhov chaw nrog kev hloov pauv kub loj. Qhov no yog qhov tseem ceeb tshwj xeeb qhov twg xav tau kev ntsuas siab.
3. Muaj zog tiv taus corrosion: Granite muaj kev tiv thaiv corrosion zoo rau ntau yam tshuaj lom neeg, thiab tuaj yeem tswj tau kev ua haujlwm ruaj khov txawm tias nyob rau hauv qhov chaw ua haujlwm hnyav.
4. Tsis muaj kev saib xyuas tshwj xeeb: Piv nrog cov khoom siv hlau, cov khoom siv granite precision tsis xav tau kev kho tshwj xeeb tiv thaiv xeb thiab tiv thaiv xeb, thiab tus nqi txij nkawm qis dua.
Qhov thib ob, qhov tsis zoo ntawm cov khoom siv granite precision
1. Qhov hnyav loj: Qhov ceev ntawm granite siab dua, yog li tib lub ntim ntawm cov khoom granite hnyav dua li cov khoom hlau. Qhov no, qee qhov, txwv nws daim ntawv thov hauv cov xwm txheej uas xav tau kev tsim qauv sib dua.
2. Kev nyuaj ua haujlwm siab: Vim yog qhov nyuaj heev ntawm granite, cov khoom siv thiab cov cuab yeej tshaj lij yuav tsum tau siv rau hauv cov txheej txheem ua haujlwm, thiab qhov nyuaj ua haujlwm thiab tus nqi kuj siab.
3. Kev tawg yooj yim: piv rau hlau, granite yog brittle thiab yooj yim tawg lossis puas tsuaj thaum raug kev cuam tshuam lossis kev co.
Peb, qhov zoo ntawm cov khoom siv hlau
1. Kev tsim qauv sib dua: Qhov ceev ntawm cov khoom siv hlau yog qhov tsawg, uas tuaj yeem ua tiav kev tsim qauv sib dua thiab ua tau raws li qhov yuav tsum tau ua ntawm qhov hnyav hauv aerospace, automotive thiab lwm yam teb.
2. Kev ua hluav taws xob zoo thiab thermal conductivity: hlau yog tus coj hluav taws xob zoo thiab tus coj cua sov zoo, uas ua rau cov khoom siv hlau muaj ntau yam kev cia siab hauv kev siv hluav taws xob, hluav taws xob thiab lwm yam.
3. Kev ua tau yooj yim: Qhov nyuaj ua cov khoom siv hlau yog qhov tsawg, thiab ntau yam kev ua thiab cov khoom siv tuaj yeem siv rau kev ua, nrog kev ua haujlwm siab.
Plaub, qhov tsis zoo ntawm cov khoom siv hlau
1. Yooj yim xeb: Cov khoom siv hlau yooj yim xeb hauv cov av noo, kua qaub lossis alkaline ib puag ncig, cuam tshuam rau lub neej kev pabcuam thiab kev ruaj khov ntawm kev ua haujlwm.
2. Cov coefficient loj ntawm kev nthuav dav thermal: cov coefficient ntawm kev nthuav dav thermal ntawm cov hlau yog qhov loj heev, thiab nws yooj yim hloov qhov loj me hauv ib puag ncig nrog kev hloov pauv kub loj, cuam tshuam rau qhov tseeb.
3. Xav tau kev saib xyuas tshwj xeeb: Cov khoom siv hlau xav tau kev kho tshwj xeeb xws li tiv thaiv xeb thiab tiv thaiv xeb thaum siv, thiab tus nqi saib xyuas siab.
V. Xaus Lus
Hauv kev xaus, cov khoom siv granite precision thiab cov khoom siv hlau muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Thaum xaiv cov khoom, yuav tsum tau xav txog ntau yam raws li cov xwm txheej thiab cov kev cai ntawm daim ntawv thov. Rau cov sijhawm uas xav tau qhov tseeb siab, kev ruaj khov siab thiab kev tiv thaiv corrosion, cov khoom siv granite precision yog qhov kev xaiv zoo dua; Rau cov ntawv thov uas xav tau kev tsim qauv sib dua, kev ua hluav taws xob zoo lossis yooj yim ua tiav, cov khoom siv hlau yuav tsim nyog dua. Los ntawm kev xaiv thiab daim ntawv thov tsim nyog, peb tuaj yeem ua si tag nrho rau qhov zoo ntawm ob qho khoom no thiab muab kev txhawb nqa zoo rau kev txhim kho ntawm cov teb cuam tshuam.
