Cov khoom siv nrog cov txuj ci tshwj xeeb-Tungsten
Koj tuaj yeem pom tungsten ntawm qhov chaw ua haujlwm thaum twg los xij.Vim tias tsis muaj lwm yam hlau tuaj yeem sib piv nrog tungsten thaum nws tuaj yeem tiv taus cua sov.Tungsten muaj qhov siab tshaj plaws melting point ntawm tag nrho cov hlau thiab yog li ntawd kuj haum rau high-temperature daim ntaub ntawv.Nws kuj yog characterized los ntawm ib tug ...Nyeem ntxiv -
Kev ceev faj rau kev siv cov khoom tungsten thiab molybdenum
1. Kev khaws cia cov khoom tungsten thiab molybdenum yog ib qho yooj yim rau oxidize thiab hloov xim, yog li lawv yuav tsum tau muab cia rau hauv ib puag ncig uas muaj av noo qis dua 60%, qhov kub ntawm 28 ° C, thiab cais los ntawm lwm yam tshuaj.Cov oxides ntawm tungsten thiab molybdenum cov khoom yog soluble hauv dej thiab yog acidic, pl ...Nyeem ntxiv -
Ntau lawm technology ntawm tungsten phaj
Hmoov metallurgy tungsten feem ntau muaj cov nplej zoo, nws qhov khoob yog feem ntau xaiv los ntawm kev kub siab forging thiab dov txoj kev, qhov kub yog feem ntau tswj ntawm 1500 ~ 1600 ℃.Tom qab qhov khoob, lub tungsten tuaj yeem txuas ntxiv dov, forged lossis spun.Xovxwm...Nyeem ntxiv -
Kev siv Molybdenum hlau, Molybdenum hmoov, thiab MoO3
MoO3 Siv: Feem ntau yog siv hauv cov hmoov metallurgy los npaj molybdenum hmoov, ua catalysts, steel additives thiab pigments.Molybdenum hmoov Cov lus piav qhia: Cov khoom no yog cov hmoov hlau grey, uas yuav maj mam oxidize hauv huab cua, thiab npaj los ntawm kev txo cov molybdenum trioxide nrog hydrogen ....Nyeem ntxiv
