Molybdenum disulfide ke eng?
Molybdenum disulfide (MoS2) ke setlolo sa bohlokoa se tiileng, se tsejoang e le "morena oa lubrication e tiileng"
1. Molybdenum disulfide ke phofo e tiileng e entsoeng ka phofo ea tlhaho ea molybdenum concentrate ka mor'a ho hloekisa lik'hemik'hale.
2. 'Mala oa sehlahisoa ke o motšo le oa silevera hanyenyane, o na le metallic luster,' me o utloahala o thella ha o ama, 'me ha o qhibilihe metsing.
3. Sehlahisoa se na le melemo ea ho hasana hantle le ho se tlame. E ka ekeletsoa ho li-grease tse fapa-fapaneng ho theha boemo ba colloidal bo sa tlameng, ho eketsa lubricity le khatello e feteletseng ea mafura;
4. E boetse e loketse mocheso o phahameng, khatello e phahameng, lebelo le phahameng le maemo a ho sebetsa a mechine e phahameng, le ho lelefatsa bophelo ba tšebeletso ea thepa;
5. Mosebetsi o ka sehloohong oa molybdenum disulfide e sebelisoang e le thepa ea khohlano ke ho fokotsa khohlano ka mocheso o tlase, ho eketsa khohlano ka mocheso o phahameng, le ho fokotsa tahlehelo ea mollo.
Tšebeliso ea molybdenum disulfide (MoS2)
1. Lubrication tlas'a maemo a pharaletseng a mocheso: mefuta e fapaneng e sebetsang ea oli ea ho tlotsa le grease e ka bang 60 ° C ho ea ho 350 ° C. Molybdenum disulfide solid lubricant e ka sebelisoa ho Ho sebetsa mocheso ho tloha 270 ° C ho ea ho 1000 ° C.
2. Lubrication tlas'a maemo a boima: ka kakaretso, filimi ea oli ea oli e tlotsang le mafura e ka jara moroalo o monyenyane feela. Hang ha mojaro o feta tekanyo eo e ka e jarang, filimi ea oli e tla robeha 'me sebaka sa likhohlano se tla loma. Karolelano ea mojaro oo filimi e tlotsang e tiileng e ka o jarang ke 108Pa.
3. Lubrication tlas'a maemo a vacuum: tlas'a maemo a phahameng a vacuum, mouoane oa oli ea lubricating le grease o batla o le moholo, o leng bonolo ho senya tikoloho ea vacuum le ho ama ts'ebetso ea ts'ebetso ea likarolo tse ling. Molybdenum disulfide solid lubricating material hangata e sebediswa bakeng sa ho tlotsa.
4. Ho tlotsa tlas'a maemo a mahlaseli: Tlas'a maemo a mahlaseli a kotsi, lisebelisoa tsa metsi tse akaretsang li tla polisa kapa li bola 'me li lahleheloe ke thepa ea tsona ea ho tlotsa. Lisebelisoa tse tiileng li na le khanyetso e ntle ea mahlaseli.
5. Lubrication ea conductive sliding surface: Ka mohlala, khohlano ea conductive sliding surface, joalo ka borashe ba motlakase ba motlakase, selaela se tsamaisang, selikalikoe sa pokello ea letsatsi ho sathelaete ea maiketsetso e sebetsang ka vacuum le khokahano ea motlakase e thellang, e ka tlotsoa ka lisebelisoa tse kopaneng tse entsoeng. ea carbon graphite kapa tšepe.
6. Maemo a nang le maemo a mabe haholo a tikoloho: Maemong a matla a tikoloho, joalo ka mechini ea lipalangoang, metjhini ea boenjiniere, mekhatlo ea indasteri ea metallurgical le tšepe le tšepe, mochini oa merafo le likarolo tse ling tsa phetisetso tse sebetsang ka lerōle, sediment, mocheso o phahameng le mongobo le tikoloho e meng e thata. Maemong a mang, molybdenum disulfide setlolo se tiileng se ka sebelisoa bakeng sa ho tlotsa.
6. Tikoloho e senyang: Ka mohlala, likarolo tse fetisoang tsa mechine ea metsing le mechine ea lik’hemik’hale li sebetsa metsing (mouoane), metsi a leoatle, asiti, alkali, letsoai le lintho tse ling tse senyang, ’me li tlameha ho ba le maemo a sa tšoaneng a ho bola ha lik’hemik’hale. Lubrication e tiileng ea Molybdenum disulfide e ka sebelisoa bakeng sa likarolo tsa phetisetso tse sebetsang boemong bona.
7. Libaka tse nang le maemo a tikoloho a hloekileng haholo: likarolo tsa phetisetso ka mechine e kang lisebelisoa tsa elektronike, masela, lijo, meriana, ho etsa pampiri, khatiso, joalo-joalo li hloka ho qoba tšilafalo, 'me setlolo se tiileng sa MoS2 se ka sebelisoa bakeng sa lubrication.
8. Maemo ntle le tlhokomelo: likarolo tse ling tsa phetisetso ha li hloke tlhokomelo, 'me likarolo tse ling tsa phetisetso li hloka ho fokotsa linako tsa tlhokomelo e le ho boloka litšenyehelo. Liketsahalong tsena, tšebeliso ea setlolo se tiileng sa MoS2 e ea utloahala, e bonolo ebile e ka boloka chelete.
