Molybdenum disulfide CAS 1317-33-5

Kodi Molybdenum disulfide ndi chiyani?

Molybdenum disulfide (MoS2) ndi mafuta olimba ofunikira, omwe amadziwika kuti "king of solid lubrication"

1. Molybdenum disulfide ndi ufa wokhazikika wopangidwa kuchokera ku molybdenum concentrate powder pambuyo poyeretsa mankhwala.
2. Mtundu wa mankhwalawo ndi wakuda komanso wotuwa pang'ono, wokhala ndi zitsulo zonyezimira, ndipo umakhala woterera ukakhudza, ndipo susungunuka m'madzi.
3. Mankhwalawa ali ndi ubwino wobalalika wabwino komanso wosamangirira. Zitha kuwonjezeredwa kumafuta osiyanasiyana kuti apange dziko losamanga la colloidal, kuonjezera mafuta ndi kupanikizika kwambiri kwa mafuta;
4. Ndiwoyeneranso kutentha kwambiri, kuthamanga kwambiri, kuthamanga kwambiri komanso kunyamula katundu wamakina ogwirira ntchito, ndikuwonjezera moyo wautumiki wa zida;
5. Ntchito yaikulu ya molybdenum disulfide yomwe imagwiritsidwa ntchito ngati chipwirikiti ndi kuchepetsa kukangana pa kutentha kochepa, kuonjezera kukangana pa kutentha kwakukulu, ndi kuchepetsa kutayika kwa moto.

Kugwiritsa ntchito molybdenum disulfide (MoS2)

1. Kupaka pansi pa kutentha kwakukulu: mafuta odzola ndi mafuta ogwiritsidwa ntchito ndi pafupifupi 60 ° C mpaka 350 ° C. Mafuta a Molybdenum disulfide olimba angagwiritsidwe ntchito pa kutentha kwa 270 ° C mpaka 1000 ° C.
2. Kupaka pansi pa katundu wolemetsa: kawirikawiri, filimu yamafuta yamafuta opaka mafuta ndi mafuta imatha kunyamula katundu wochepa. Katunduyo akadzadutsa mtengo womwe ungathe kupirira, filimu yamafuta imasweka ndipo nsonga yamphepo imaluma. Kulemera kwapakati komwe filimu yothira mafuta imatha kunyamula ndi 108Pa.
3. Mafuta odzola pansi pazitsulo zotsekemera: pansi pa mikhalidwe yambiri ya vacuum, kutuluka kwa mafuta odzola ndi mafuta kumakhala kwakukulu, komwe n'kosavuta kuwononga chilengedwe cha vacuum ndikukhudza kugwira ntchito kwa zigawo zina. Mafuta olimba a Molybdenum disulfide amagwiritsidwa ntchito popaka mafuta.
4. Kupaka mafuta m'nyengo ya radiation: Munthawi ya radiation, mafuta amadzimadzi amadzimadzi amatha polymeriza kapena kuwola ndikutaya mphamvu zake zokometsera. Mafuta olimba amakhala ndi mphamvu yokana ma radiation.
5. Mafuta a conductive kutsetsereka pamwamba: Mwachitsanzo, mikangano ya conductive kutsetsereka pamwamba, monga burashi magetsi a galimoto magetsi, conductive slider, solar otolera mphete pa yokumba Kanema ntchito vacuum ndi kutsetsereka kukhudzana magetsi, akhoza afewetsedwa ndi gulu zipangizo zopangidwa carbon graphite kapena zitsulo.
6. Mikhalidwe yoyipa kwambiri zachilengedwe: Muzovuta zachilengedwe, monga makina oyendera, makina opangira uinjiniya, zitsulo ndi chitsulo ndi zitsulo, makina opangira migodi ndi magawo ena opatsirana omwe amagwira ntchito mu fumbi, matope, kutentha kwakukulu ndi chinyezi ndi zina zowopsa zachilengedwe. Nthawi zina, mafuta olimba a molybdenum disulfide amatha kugwiritsidwa ntchito popaka mafuta.
6. Malo owononga: Mwachitsanzo, mbali zopatsirana zamakina a m’madzi ndi makina a mankhwala zimagwira ntchito m’madzi (nthunzi), madzi a m’nyanja, asidi, alkali, mchere ndi zinthu zina zowononga, ndipo zimafunika kuzimbirira mosiyanasiyana. Mafuta olimba a Molybdenum disulfide angagwiritsidwe ntchito potengera magawo omwe akugwira ntchito ngati izi.
7. Malo okhala ndi chilengedwe choyera kwambiri: ziwalo zotumizira mu makina monga zamagetsi, nsalu, chakudya, mankhwala, kupanga mapepala, kusindikiza, ndi zina zotero ziyenera kupeŵa kuipitsidwa, ndipo mafuta olimba a MoS2 angagwiritsidwe ntchito popaka mafuta.
8. Mikhalidwe popanda kukonza: mbali zina zotumizira sizifunikira kukonzedwa, ndipo zina zotumizira zimayenera kuchepetsa nthawi yokonza kuti zisunge ndalama. Munthawi izi, kugwiritsa ntchito mafuta olimba a MoS2 ndikoyenera, kosavuta komanso kungapulumutse ndalama.

Makhalidwe a Molybdenum disulfide

Maselo a MoS2: S=Mo=S
Kuchuluka kwa MoS2: 4.5 – 4.8 g/cm³
