Kev tu txhua hnub rau Microscopes
Yog tias koj lub tshuab tsom iav khaws cia rau hauv qhov chaw ntub dej, thov ua tib zoo saib cov ntsiab lus hauv qab no: Cov av noo nyob sab hauv tsev yog qhov ua rau pwm loj hlob ntawm qhov muag qhov muag. Thaum pwm cov ntaub ntawv ntawm lub lens nto, nws yog qhov nyuaj heev los tshem tawm. Lub lens sab hauv ntawm lub tshuab tsom iav yog qhov yooj yim dua rau kev puas tsuaj vim tias lawv tsis tuaj yeem ntxuav tau yooj yim. Tsis tas li ntawd, cov khoom siv kho tshuab zoo li xeb tom qab nqus dej. Rau kev khaws cia tsis muaj dej noo, xaiv chav qhuav, thiab tso lub tshuab ntsuas kom deb ntawm cov phab ntsa, hauv pem teb thiab qhov chaw noo noo. Piv txwv li, muab 1 mus rau 2 lub hnab ntawm silica gel desiccant nyob rau hauv lub microscope case, thiab reactivate lub silica gel tsis tu ncua. Thaum nws hloov xim liab, ci nws sai sai rau rov siv dua.
Tiv thaiv plua plav
Cov neeg siv yuav pom tau tias daim duab ntawm lub tshuab tsom iav yuav tsis ntse tom qab siv mus ntev. Tsis txhob maj mus xaus tias lub tshuab tsom iav nws tus kheej yog qhov tsis zoo. Qhov teeb meem no feem ntau tshwm sim los ntawm kev tiv thaiv plua plav tsis txaus. Plua plav ntawm cov khoom siv kho qhov muag thaiv lub teeb kis tau tus mob. Tom qab tau nthuav dav los ntawm qhov kho qhov muag, cov plua plav yuav tsim cov smudges loj thiab cuam tshuam nrog kev soj ntsuam. Plua plav thiab grit nkag mus rau hauv cov khoom sib dhos yuav ua rau kom hnav thiab ua rau lub zog qeeb, uas yog qhov teeb meem. Yog li ntawd, khaws lub tshuab ntsuas kom huv txhua lub sijhawm. Npog nws nrog plua plav npog thaum tsis siv.
Tiv thaiv corrosion
Tsis txhob khaws lub tshuab tsom iav ua ke nrog corrosive tshuaj reagents xws li sulfuric acid, hydrochloric acid thiab muaj zog alkalis.
Kev Tiv Thaiv Thaum Kub Kub
Qhov xwm txheej no yuav tsum tsis txhob saib dhau. Kev tiv thaiv tshav kub feem ntau tiv thaiv lub lens cement sib cais thiab delamination los ntawm thermal expansion thiab contraction.
