Khoom Description
Molybdenum discsyog ua los ntawm cov nplooj ntawv molybdenum uas tau txiav los yog stamped, thiab saum npoo tuaj yeem polished lossis polished. Molybdenum discs tuaj yeem siv los ua LED substrates, thiab tuaj yeem ua rau qhov ntau thiab tsawg los ntawm 2 ntiv mus rau 10 ntiv tes.Raws li cov khoom siv ntawm cov hlau refractory molybdenum, nws yog ib daim ntawv puag ncig ua los ntawm high-purity molybdenum hmoov thiab additives xws li nickel hmoov los yog hlau hmoov, nrog ib tug purity txog li 99.7%, feem ntau nrog ib tug tej thickness thiab txoj kab uas hla, thiab ib tug flatness ntawm tsawg dua los yog sib npaug zos rau 3%. Nws yog tsim nyog hais tias cov kev siv tshwj xeeb ntawm molybdenum discs ntawm txawv diameters thiab thicknesses kuj txawv.

Cov khoom sib koom tes duab
1.Los ntawm qhov pom ntawm qhov pom,molybdenum discsfeem ntau yog xim av-xim av, tab sis lawv feem ntau yog nyiaj-grey tom qab alkali ntxuav, nrog siab gloss, thiab nto yog du thiab tiaj tus, tsis muaj qhov tsis xws luag xws li tawv tawv, delamination, impurity suav nrog, tawg thiab tawg. Los ntawm qhov kev xav ntawm lub cev thiab tshuaj lom neeg, molybdenum discs muaj cov yam ntxwv ntawm lub siab melting point (2620 degree), ceev (10.2g / cm3), hardness (Mohs hardness yog 5 ~ 5.5) thiab lub zog, tsawg thermal expansion coefficient thiab resistivity, siab conductivity, zoo tshuaj stability (tsis yooj yim rau react nrog acids, alkalis thiab ntsev), kub creep kuj, oxidation kuj, kub kuj thiab corrosion kuj.
2.Muaj ob txoj kev tsim khoom tseem ceeb raumolybdenum discs, ib qho yog hmoov metallurgy thiab lwm yam yog kub dov. Hmoov metallurgy yog sib tov molybdenum hmoov nrog rau lwm yam alloying ntsiab thiab daim ntawv discs los ntawm kub nias ntawm kub thiab siab. Cov txheej txheem kub dov yog dov lub molybdenum billet rau hauv cov duab ntawm qhov kub thiab txias, thiab tom qab ntawd ua cov kauj ruam xws li annealing thiab alkali ntxuav, uas tuaj yeem siv tau kom tau cov nplooj ntawv molybdenum.
