Refractory cov ntaub ntawv thov ntawm electron microscopy
Vim cov tshuaj muaj pes tsawg leeg ntawm refractories, ntxhia muaj pes tsawg leeg thiab microstructure txiav txim qhov xwm ntawm refractories; refractories tshuaj muaj pes tsawg leeg ntawm cov kev tshiab ntawm kev tsom xam yog, colorimetric txoj kev, organic reagents ( complex) titration, nplaim photometric txoj kev, spectral tsom xam, X-ray fluorescence tsom xam, thiab lwm yam .; thiab polarizing microscope thiab scanning electron microscope yog cov refractory ntxhia muaj pes tsawg leeg thiab microstructure ntawm kev tsom xam ntawm * zoo txhais tau tias, yog li zoo-zoo polarizing microscope thiab scanning electron microscope yog tam sim no ib qho tseem ceeb cov cuab yeej rau kev tsim khoom thiab R & D hauv kev tsim khoom thiab kev soj ntsuam. thiab kev taw qhia ntawm cov txheej txheem ntau lawm. Yog li ntawd, qhov zoo tshaj plaws polarizing microscope thiab scanning electron microscope yog cov cuab yeej tseem ceeb rau kev ntsuam xyuas, ntsuas thiab coj cov txheej txheem tsim khoom hauv kev tsim khoom thiab kev tshawb fawb thiab kev tsim cov lag luam refractories.
Polarizing microscope thiab scanning electron microscope hauv cov ntaub ntawv refractory hauv daim ntawv thov tshwj xeeb rau:
Ua ntej, ua lub teeb pom kev zoo polarized thiab tshuaj ntsuam xyuas electron microscope ntawm cov ntaub ntawv refractory ntxhia muaj pes tsawg leeg thiab kev tsom xam microstructure. Cov khoom ntawm cov khoom siv refractory feem ntau suav nrog cov tshuaj-mineral muaj pes tsawg leeg, cov qauv tsim, cov khoom siv kho tshuab, cov khoom siv thermal thiab cov khoom siv kub. Cov khoom siv refractory yog lub cev tsis yog homogeneous muaj li ntawm ob ntu: cov theem khoom (nrog rau theem crystalline thiab glassy theem) thiab qhov pores. Qhov txheeb ze kom muaj nuj nqis thiab kev faib tawm ntawm lawv thiab kev sib xyaw ntawm morphology yog qhov microstructure ntawm cov ntaub ntawv refractory. Lub cev thiab tshuaj muaj zog ntawm refractories yog txiav txim los ntawm lub crystalline theem ntawm refractories. Cov qauv crystalline yog txiav txim siab los ntawm cov txheej txheem tsim khoom ntawm refractory thiab cov zaub mov siv los ua cov khoom xyaw. Los ntawm lub tshuab microscope thiab scanning electron microscope yog tsuas yog los soj ntsuam cov ntaub ntawv refractory ntawm crystalline qauv thiab roj theem qauv, thiaj li coj cov ntaub ntawv refractory ntawm cov txheej txheem ntau lawm thiab kev faib ua feem ntawm cov minerals ntxiv rau cov khoom xyaw, thiab lwm yam., thiab thaum kawg. ua tiav cov ntaub ntawv refractory ntawm lub cev thiab tshuaj lom neeg cov khoom ntawm cov khoom siv refractory, nyob rau hauv txoj kab nrog cov ntaub ntawv refractory ntawm daim ntawv thov kev ua tau zoo.
Thib ob, kev siv lub teeb pom kev zoo polarized thiab scanning electron microscope ntawm refractoriness ntawm cov khoom refractory, thermal poob siab stability, porosity tis, tsis kam mus slagging thiab corrosion kev ua tau zoo ntawm kev ntsuam xyuas thiab kev tsom xam, kom txhim kho cov khoom zoo ntawm refractory, ua tau raws li kev lag luam tam sim no rau cov tiam tshiab ntawm cov khoom siv hluav taws xob siab tshaj plaws.
