Yuav Ua Li Cas Saib Xyuas thiab Tswj Xyuas Metallographic Microscopes
Ntau tus neeg muas zaub, tom qab yuav lub tshuab ntsuas metallographic, tsis tswj nws raws sijhawm, uas tuaj yeem ua rau cov duab tsis meej. Qee cov tuam txhab lag luam txawm xav tau cov chaw tsim tshuaj ntsuam xyuas kom tswj tau nws txhua xyoo, nrog tus nqi saib xyuas kwv yees li 1500 RMB. Ntawm no, kuv yuav sau txog yuav ua li cas ua haujlwm yooj yim txhua hnub thiab tu kom txuag tau ntawm cov nqi siv.
Ua ntej, nyob rau hauv cov nqe lus ntawm kev tu lub lens thiab lim, tsis txhob cia cov plua plav, ntiv tes, thiab lwm yam nyob rau hauv lub lens thiab lim ntawm metallographic microscope. Tshem tawm cov av ntawm lub lens thiab lim yuav cuam tshuam rau kev soj ntsuam cov duab; Yog tias ib qho lens ua qias neeg, siv txhuam txhuam kom tshem cov plua plav lossis so kom huv nrog cov ntaub qhwv ntsej, tsis tas yuav haus cawv. Tsuas yog thaum muaj cov ntiv tes lossis roj rau ntawm lub tshuab ntsuas metallographic, siv cov cawv tsis muaj dej (xws li ethyl cawv lossis methanol) dipped rau hauv ib daim ntaub huv thiab mos, daim ntawv lo ntsiab muag lossis cov ntaub qhwv ua ntej so. Anhydrous cawv yog flammable heev, yog li ceev faj thaum siv nws, tshwj xeeb tshaj yog thaum siv hluav taws nyob ze los yog qhib / tawm fais fab hloov.
Thaum ntxuav cov txheej, yas, thiab cov khoom luam tawm nrog lub tshuab ntsuas metallographic, tsis txhob siv cov kuab tshuaj organic (cawv, ether, xim thinner, thiab lwm yam) ntawm cov txheej, yas, lossis cov khoom luam tawm, vim qhov no yuav ua rau cov ntawv luam tawm ploj lossis poob.
Yog tias cov av ntawm lub tshuab ntsuas metallographic yog qhov nyuaj rau tshem tawm, thov maj mam so nws nrog ib daim ntaub ntub dej hauv nruab nrab. (Hauv chav huv, siv chav huv huv los so cov ntaub qhwv.)
Metallographic microscopes, tshwj xeeb tshaj yog imported microscopes, kuj kim heev rau kev yuav khoom, yog li kev saib xyuas txhua hnub yog qhov tseem ceeb. Nws raug nquahu kom npog lawv nrog paj rwb ntaub tom qab kev yuav khoom los tiv thaiv cov plua plav thiab cov khib nyiab los ntawm kev sib kis ntawm lub qhov muag thiab lub hom phiaj lens, uas yog qhov tseem ceeb tshaj plaws ntawm lub tshuab tsom.
