Dab tsi yog qhov hnav tsis kam ntawm cov khoom siv granite precision?

Cov khoom siv granite precision yeej ib txwm yog ib feem tseem ceeb ntawm ntau yam lag luam xws li kev tsim khoom, tsheb, thiab aerospace. Lawv siv rau ntau yam kev siv vim lawv lub zog ruaj khov, kev ruaj khov, thiab qhov tseeb. Ib qho ntawm cov yam tseem ceeb ntawm cov khoom granite yog lawv txoj kev tiv thaiv kev hnav, uas ua rau lawv zoo tagnrho rau kev siv hauv cov chaw ib puag ncig thiab cov ntawv thov hnyav.

Kev tiv thaiv kev hnav yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev hnav, kev yaig lossis kev puas tsuaj vim muaj kev sib cuam tshuam nrog ib puag ncig lossis lwm yam khoom siv. Granite muaj kev tiv thaiv kev hnav zoo tshaj plaws piv rau feem ntau lwm yam khoom siv. Thaum xav txog kev tiv thaiv kev hnav ntawm cov khoom granite precision, cov hauv qab no yuav tsum tau xav txog:

Qhov nyuaj

Granite yog ib yam khoom siv uas ruaj khov thiab ntom ntom, uas ua rau nws zoo heev rau kev hnav. Qhov nyuaj ntawm granite yog ntsuas ntawm Mohs scale, uas yog txij li 1 txog 10, thiab granite muaj qib 7. Qhov no txhais tau tias cov khoom granite tiv taus kev hnav thiab tuaj yeem siv tas li hauv cov xwm txheej hnyav yam tsis muaj kev puas tsuaj loj.

Qhov chaw tiav

Qhov ua tiav ntawm cov khoom siv granite precision kuj tseem tuaj yeem ua lub luag haujlwm tseem ceeb hauv lawv cov khoom tiv taus hnav. Ib qho chaw zoo polished thiab du yuav pab txo qhov kev sib txhuam thiab hnav. Qhov ua tiav ntawm qhov chaw no yog ua tiav los ntawm kev ua haujlwm precision thiab polishing txheej txheem. Qhov siab dua ntawm kev polishing, qhov du dua, thiab nws qhov kev tiv taus hnav zoo dua.

Kev tiv thaiv tshuaj lom neeg

Granite yog ib yam khoom siv uas tsis muaj zog, uas txhais tau tias nws tiv taus tshuaj lom neeg heev. Qhov no ua rau nws yog ib yam khoom siv tsim nyog rau cov ntawv thov uas raug tshuaj lom neeg. Qhov tsis kam ntawm granite rau acid thiab alkali ua rau nws ruaj khov heev thiab tsis tshua hnav.

Kev ruaj khov ntawm cua sov

Cov khoom siv granite ruaj khov heev nyob rau hauv qhov chaw kub heev. Qhov coefficient qis ntawm thermal expansion ntawm granite ua rau nws tsis tshua muaj peev xwm deform lossis tawg txawm tias thaum raug rau qhov kub siab. Qhov no ua rau cov khoom siv granite tsim nyog rau kev siv hauv cov ntawv thov uas xav tau kev ua haujlwm siab, xws li metrology, qhov twg kev tswj kub yog qhov tseem ceeb.

Xaus lus, cov khoom siv granite precision yog cov khoom siv uas tsis yooj yim hnav thiab tuaj yeem tiv taus cov xwm txheej ib puag ncig hnyav. Lawv qhov nyuaj, qhov tiav ntawm qhov chaw, kev tiv taus tshuaj lom neeg, thiab kev ruaj khov thermal ua rau lawv zoo tagnrho rau kev siv rau hauv cov ntawv thov uas xav tau kev ruaj khov thiab kev ua kom raug. Cov khoom siv granite zoo tuaj yeem siv tau ntau xyoo, ua rau lawv yog cov kev daws teeb meem pheej yig thiab txhim khu kev qha rau ntau yam lag luam.
