Qhov tseem ceeb sib txawv ntawm microscope thiab magnifying iav
Microscope kuj yog ib qho cuab yeej pab rau qhov muag. Nws yog tsuas yog siv los saib xyuas cov ntsiab lus me me ntawm cov khoom ze. Nws yog dav siv nyob rau hauv ntau yam scientific thiab technical teb thiab yog ib qho tseem ceeb heev qhov muag pom kev ntsuas.
Ua hauj lwm hauv paus ntsiab lus ntawm microscope
Microscope thiab magnifying iav ua si tib lub luag haujlwm, uas yog, tsim cov duab loj ntawm ib qho khoom me me ntawm qhov ze, thiab qhib lub kaum sab xis ntawm daim duab rau tib neeg lub qhov muag loj dua li thaum tib neeg lub qhov muag ntsia ntawm qhov khoom. ncaj qha.
Qhov sib txawv ntawm lawv yog qhov loj ntawm cov iav tsom iav tsis siab, feem ntau hauv qab 15X; Qhov pom kev nthuav dav ntawm lub tshuab microscope tuaj yeem ncav cuag ntau dua 1000 zaug.
Magnifier qauv yog qhov yooj yim, feem ntau tsuas yog ib pawg ntawm lo ntsiab muag, cov ntsiab lus yog qhov loj; Txawm li cas los xij, lub microscope muaj cov qauv tsim, feem ntau yog ob txheej ntawm lo ntsiab muag, thiab nws cov ntsiab lus yog qhov kev nthuav dav thib ob.
Lub hauv paus ntsiab lus ntawm kev nthuav dav thib ob ntawm lub tshuab tsom iav yog thawj zaug siv lub lens nrog qhov ntev focal ntev los ua ib qho khoom me me rau hauv cov duab tiag tiag, uas yog, txhawm rau nthuav cov khoom kab rov tav ob peb zaug, thiab tom qab ntawd siv lub iav tsom iav kom pom qhov tseem ceeb. duab uas tau nthuav dav horizontally.
Muaj ntau daim ntawv thov ntawm microscope hauv kev tsim khoom
1. Kev tshuaj xyuas cov ntaub ntawv raw los ntawm metallographic microscope: kev tshuaj xyuas cov khoom siv hlau zoo ntawm cov khoom siv raw xws li kev sib cais, faib hom thiab qib ntawm nonmetallic inclusions; Txheeb xyuas qhov porosity, porosity thiab slag suav nrog uniformity ntawm cov khoom siv casting; Tshawb xyuas qhov chaw forged rau decarburization, overheating, overburning, tawg thiab deformation.
2. Kev tswj kom zoo nyob rau hauv cov txheej txheem ntau lawm: metallographic microscope tuaj yeem muab lub hauv paus rau kev kho cov txheej txheem thiab hloov cov txheej txheem tsis ua haujlwm, thiab coj cov kev tsim khoom, xws li seb qhov ntsuas kub ntawm kev kho cua sov thiab quenching, lub sij hawm ntawm kev txuag hluav taws xob thiab cov txias npaum li cas yog tsim nyog (yog); Kev tswj cov txheej txheem tsis muaj tshuaj lom neeg qhov chaw kho cua sov; Seb qhov pib thiab qhov kawg forging kub ntawm forging yog tsim nyog, thiab lwm yam.
3. Kev soj ntsuam tsis tiav ntawm lub tshuab ntsuas metallographic: metallographic qauv kev tsom xam txoj kev yog dav siv hauv kev ntsuas kev ua haujlwm tsis zoo, uas yooj yim rau kev txheeb xyuas qee qhov tsis xws luag. Xws li decarburization ntawm qhov chaw ntawm qhov chaw; Morphology thiab faib cov yam ntxwv ntawm microcracks; Qhov tsis xws luag ntawm kev kho cua sov; Cov qauv txawv txav tom qab kev kho cua sov; Grain ciam teb nkig theem nag lossis daus, thiab lwm yam. Cov txiaj ntsig ntawm kev tshuaj ntsuam metallographic feem ntau yog siv los ua lub hauv paus ntawm kev soj ntsuam txhaum.
4. Kev tshuaj xyuas cov khoom lag luam zoo: Qee qhov khoom siv tshuab lossis cov khoom yuav tsum tsis yog tsuas yog cov khoom siv kho tshuab thiab lub cev, tab sis kuj tseem muaj microstructure tsis raws li ib qho ntawm cov kev ntsuas rau kev soj ntsuam zoo.
