Qhov sib txawv ntawm daim ntawv thov ntawm upright thiab inverted metallographic microscopes
Qhov sib txawv ntawm upright thiab inverted yog qhov yooj yim tias cov qauv upright tau muab tso rau hauv qab thiab cov qauv inverted yog muab tso rau saum toj. Lub hom phiaj upright yog tig downwards, thiab lub hom phiaj inverted yog tig upwards.
Inverted metallographic microscope, vim qhov tseeb tias qhov kev soj ntsuam saum npoo ntawm cov qauv sib txuam nrog qhov chaw ntawm qhov chaw ua haujlwm, thiab lub hom phiaj kev soj ntsuam yog nyob rau hauv qab ntawm lub workbench rau upward soj ntsuam, daim ntawv soj ntsuam no tsis txwv los ntawm qhov siab ntawm tus qauv. Thaum npaj cov qauv, tsuas yog ib qho kev soj ntsuam saum npoo yog tiaj tus, yog li nws feem ntau yog siv rau hauv cov chaw soj nstuam, cov chaw tshawb fawb tshawb fawb, thiab cov tsev kawm qib siab rau kev qhia. Lub hauv paus ntawm inverted metallographic microscope muaj thaj chaw txhawb nqa loj, qhov chaw qis ntawm lub ntiajteb txawj nqus, thiab ruaj khov thiab txhim khu kev qha. Lub qhov muag thiab qhov chaw txhawb nqa yog tilted ntawm 45 degree, ua rau kev pom zoo.
Lub upright metallographic microscope muaj tib lub luag haujlwm tseem ceeb xws li lub tshuab hluav taws xob inverted metallographic. Ntxiv rau kev txheeb xyuas thiab txheeb xyuas cov qauv hlau nrog qhov siab ntawm 20-30mm, nws tau siv ntau dua hauv cov ntaub ntawv pob tshab, pob tshab, lossis cov khoom tsis pom kev vim nws ua raws li tib neeg niaj hnub cwj pwm. Lub tshuab ntsuas metallographic upright tsim cov duab zoo thaum saib, uas ua rau muaj kev yooj yim zoo rau cov neeg siv kev soj ntsuam thiab kev ntxub ntxaug. Ntxiv rau kev txheeb xyuas thiab txheeb xyuas cov qauv hlau nrog qhov siab ntawm 20-30mm, kev soj ntsuam lub hom phiaj loj dua 3 microns tab sis me dua 20 microns, xws li cov qauv saum npoo thiab cov khoom siv xws li cermets, chips electronics, luam tawm circuits, LCD substrates, nyias zaj duab xis, fibers, khoom granular, coatings, thiab lwm yam, tuaj yeem muaj cov duab zoo.
