Molybdenum disulfide, cov tshuaj formula MoS2, yog ib qho inorganic compound nrog ntau lub cev, tshuaj, thiab hluav taws xob uas ua rau nws muaj txiaj ntsig rau ntau daim ntawv thov.

Lub cev muaj zog

Molybdenum disulfide yog grey-dub khoom, teej tug mus rau hexagonal system.Nws cov qauv molecular muaj ob txheej ntawm S atoms thiab ib txheej ntawm Mo atoms, zoo ib yam li cov qauv ntawm graphite.Raws li cov qauv no, molybdenum disulfide lub cev muaj cov khoom nram qab no:

1. Cov txheej txheem txheej: Molybdenum disulfide muaj cov txheej txheem txheej txheej, uas ua rau nws muaj lub siab tawv nyob rau hauv ob sab kev taw qhia, thiab yog dav siv nyob rau hauv ntau yam lubricants thiab kev sib txhuam thiab hnav teb.

2. High thermal conductivity: Molybdenum disulfide muaj cov thermal conductivity siab heev, uas ua rau nws ruaj khov ntawm qhov kub thiab txias thiab siv los ua cov khoom siv thermal conductivity.

3. Zoo tshuaj stability: molybdenum disulfide qhia tau hais tias zoo stability nyob rau hauv high kub thiab tshuaj corrosion ib puag ncig, uas ua rau nws ib tug zoo kub tshuaj catalyst nrog dav daim ntawv thov.

Cov cuab yeej tshuaj

Molybdenum disulfide muaj cov tshuaj lom neeg ruaj khov, thiab muaj kev ruaj ntseg rau oxidation, txo qis, acid, alkali thiab lwm qhov chaw.Nws yog rhuab mus rau 600 ℃ nyob rau hauv cov huab cua thiab tseem tsis decompose.Hauv cov tshuaj tiv thaiv, molybdenum disulfide feem ntau ua raws li cov khoom siv hluav taws xob lossis cov khoom thauj, muab lub chaw ua haujlwm los txhawb cov tshuaj tiv thaiv.

Hluav taws xob khoom

Molybdenum disulfide muaj cov khoom siv hluav taws xob zoo thiab yog cov khoom siv semi-hlau.Nws cov qauv band muaj qhov sib txawv ntawm qhov sib txawv, uas ua rau nws muaj peev xwm siv tus nqi hauv semiconductor teb.Molybdenum disulfide kuj tseem siv los ua lub dab dej kub thiab cov khoom siv hluav taws xob sib txuas hauv cov khoom siv hluav taws xob.

siv

Vim yog cov khoom zoo heev ntawm molybdenum disulfide, nws tau siv dav hauv ntau qhov chaw:

1. Lubricants: Molybdenum disulfide yog dav siv nyob rau hauv ntau yam machinery thiab bearing lubricants vim nws cov txheej txheem txheej thiab kub stability, uas yuav zoo heev txhim kho efficiency thiab lub neej ntawm machinery.

2. Catalyst: Molybdenum disulfide yog siv los ua catalyst los yog cov cab kuj nyob rau hauv ntau cov tshuaj tiv thaiv, xws li Fischer-Tropsch synthesis, alkylation cov tshuaj tiv thaiv, thiab lwm yam. Nws zoo heev tshuaj stability ua rau nws lug siv nyob rau hauv kev lag luam tshuaj.

3. Cov khoom siv thermal conductivity siab: Vim lub siab thermal conductivity ntawm molybdenum disulfide, nws yog siv los ua cov khoom siv thermal conductivity, xws li thermal conductivity ntsiab nyob rau hauv high temperature reactors.

4. Cov khoom siv hluav taws xob: Cov khoom siv hluav taws xob ntawm molybdenum disulfide ua rau nws siv hauv cov khoom siv hluav taws xob, xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.

Molybdenum disulfide yog dav siv nyob rau hauv ntau lub teb vim hais tias ntawm nws cov cim lub cev, tshuaj thiab hluav taws xob zog.Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov teb ntawm molybdenum disulfide yuav txuas ntxiv nthuav dav, ua kom yooj yim dua thiab muaj txiaj ntsig rau tib neeg kev tsim khoom thiab lub neej.
