Lub Luag Haujlwm ntawm Granite hauv Kev Tsim Cov Lens High-Precision.

 

Granite, ib lub pob zeb igneous ntuj tsim los ntawm quartz, feldspar thiab mica, ua lub luag haujlwm tseem ceeb tab sis feem ntau tsis quav ntsej hauv kev tsim cov lens siab. Cov yam ntxwv tshwj xeeb ntawm Granite ua rau nws yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv hauv kev lag luam kho qhov muag, tshwj xeeb tshaj yog rau kev tsim cov lens zoo rau cov koob yees duab, microscopes thiab telescopes.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm granite yog nws qhov ruaj khov tshwj xeeb. Thaum tsim cov iav tsom iav siab, kev tswj kom muaj qhov chaw ruaj khov thiab ruaj khov yog qhov tseem ceeb kom ntseeg tau tias qhov muag pom tseeb thiab raug. Granite qhov coefficient qis ntawm thermal expansion txhais tau tias nws yuav tsis khoov lossis deform nrog qhov kub thiab txias hloov pauv, ua rau nws yog cov khoom siv zoo tagnrho rau kev sib tsoo lens thiab polishing khoom siv. Qhov kev ruaj khov no tso cai rau cov chaw tsim khoom kom ua tiav qhov kev kam rau siab uas xav tau rau cov khoom siv kho qhov muag ua tau zoo.

Qhov tawv ntawm granite kuj ua rau nws tseem ceeb hauv kev tsim cov lens. Cov khoom siv no tuaj yeem tiv taus cov txheej txheem sib tsoo thiab polishing uas xav tau los tsim cov nplaim du thiab tsis muaj qhov tsis zoo uas xav tau rau cov lens siab. Tsis zoo li cov ntaub ntawv mos dua, granite tsis yooj yim hnav, ua kom ntseeg tau tias cov cuab yeej siv hauv kev tsim cov lens yuav tswj tau lawv qhov ua tau zoo dhau sijhawm. Qhov kev ruaj khov no txuag cov tuam txhab tsim khoom nyiaj vim tias lawv tuaj yeem cia siab rau cov khoom siv granite ntev yam tsis tas yuav hloov nws ntau zaus.

Tsis tas li ntawd xwb, granite qhov zoo nkauj ntuj thiab ntau yam xim tuaj yeem ua rau cov khoom siv kho qhov muag zoo nkauj dua. Txawm hais tias kev ua haujlwm yog qhov tseem ceeb, qhov cuam tshuam ntawm cov iav siab thiab lawv cov tsev kuj tuaj yeem cuam tshuam rau cov neeg siv khoom xaiv. Kev siv granite hauv cov ntawv thov no tsis yog tsuas yog muab lub hauv paus ruaj khov thiab txhim khu kev qha, tab sis kuj ntxiv ib qho ntawm kev zoo nkauj.

Hauv kev xaus, granite cov khoom tshwj xeeb (kev ruaj khov, qhov nyuaj, thiab kev zoo nkauj) ua rau nws yog cov khoom siv muaj txiaj ntsig rau kev tsim cov iav siab. Raws li qhov kev thov rau cov thev naus laus zis kho qhov muag siab heev txuas ntxiv mus, lub luag haujlwm ntawm granite hauv kev lag luam yuav tseem ceeb dua, kom ntseeg tau tias cov chaw tsim khoom tuaj yeem ua tau raws li cov qauv nruj uas xav tau rau kev ua haujlwm zoo.
