Precision granite Cheebtsam yeej ib txwm yog ib feem tseem ceeb ntawm ntau yam kev lag luam xws li kev tsim khoom, tsheb, thiab aerospace.Lawv yog siv nyob rau hauv ntau yam kev siv vim lawv zoo heev durability, stability, thiab raug.Ib qho ntawm cov ntsiab lus tseem ceeb ntawm cov khoom siv granite yog lawv cov hnav tsis kam, uas ua rau lawv zoo tagnrho rau siv nyob rau hauv ib puag ncig hnyav thiab kev siv.
Hnav tsis kam yog lub peev xwm ntawm cov khoom siv los tiv thaiv hnav, yaig lossis degradation vim muaj kev cuam tshuam nrog ib puag ncig ib puag ncig lossis lwm yam khoom siv.Granite muaj qhov tshwj xeeb hnav tsis kam piv rau feem ntau lwm cov ntaub ntawv.Thaum xav txog qhov hnav tsis kam ntawm cov khoom siv granite precision, cov hauv qab no yuav tsum tau xav txog:
Hardness
Granite yog ib yam khoom nyuaj thiab ntom ntom, uas ua rau nws zoo heev hnav tsis kam.Lub hardness ntawm granite yog ntsuas ntawm Mohs nplai, uas nyob ntawm 1 txog 10, thiab granite muaj qhov ntsuas ntawm 7. Qhov no txhais tau hais tias cov khoom siv granite muaj peev xwm tiv taus hnav thiab tuaj yeem tiv taus kev siv tas li hauv cov xwm txheej hnyav yam tsis muaj kev puas tsuaj loj.
Nto tiav
Qhov saum npoo tiav ntawm precision granite Cheebtsam tuaj yeem ua lub luag haujlwm tseem ceeb hauv lawv cov khoom hnav tsis kam.Ib qho zoo polished thiab du nto yuav pab txo kev sib txhuam thiab hnav.Qhov no nto tiav yog tiav los ntawm precision machining thiab polishing txheej txheem.Qhov siab dua ntawm polishing, qhov smoother ntawm qhov chaw, thiab qhov zoo dua nws hnav tsis kam.
Tshuaj tiv thaiv
Granite yog cov khoom siv tsis muaj tshuaj lom neeg, uas txhais tau hais tias nws muaj peev xwm tiv taus tshuaj lom neeg corrosion.Qhov no ua rau nws yog ib qho khoom siv tsim nyog rau cov ntawv thov uas cuam tshuam rau cov tshuaj inevitable.Qhov tsis kam ntawm granite rau acid thiab alkali ua rau nws ruaj khov thiab tsis tshua hnav.
Thermal stability
Granite Cheebtsam yog ruaj khov heev nyob rau hauv huab cua kub ib puag ncig.Qhov qis coefficient ntawm thermal expansion ntawm granite ua rau nws tsis tshua muaj deform lossis tawg txawm tias raug kub kub.Qhov no ua rau granite Cheebtsam haum rau siv nyob rau hauv daim ntawv thov uas yuav tsum tau high precision, xws li metrology, qhov twg kub tswj yog qhov tseem ceeb.
Hauv kev xaus, precision granite Cheebtsam yog cov hnav-tiv taus thiab tuaj yeem tiv taus ib puag ncig hnyav.Lawv hardness, nto tiav, tshuaj tiv thaiv, thiab thermal stability ua rau lawv zoo tagnrho rau siv nyob rau hauv daim ntawv thov uas yuav tsum tau durability thiab precision.Cov khoom siv granite zoo tuaj yeem siv tau ntau xyoo, ua rau lawv muaj txiaj ntsig zoo thiab txhim khu kev qha rau ntau yam lag luam.
