Iyini i-Molybdenum disulfide?
I-Molybdenum disulfide (MoS2) iyisithambiso esibalulekile esiqinile, eyaziwa ngokuthi “inkosi yokuthambisa okuqinile”
1. I-Molybdenum disulfide iyimpushana eqinile eyenziwe nge-molybdenum concentrate powder yemvelo ngemva kokuhlanzwa kwamakhemikhali.
2. Umbala womkhiqizo umnyama futhi umpunga kancane, unokukhanya kwensimbi, futhi uzwakala ushelela lapho uthintwa, futhi awuncibiliki emanzini.
3. Umkhiqizo unezinzuzo zokuhlakazeka okuhle nokungabophi. Ingangezwa kumafutha ahlukahlukene ukuze enze isimo se-colloidal esingabophi, okwandisa ukuthambisa nokucindezela okukhulu kwamafutha;
4. Ibuye ifanele izinga lokushisa eliphezulu, ukucindezela okukhulu, isivinini esikhulu kanye nezimo zokusebenza zemishini yomthwalo omkhulu, futhi yandisa impilo yesevisi yemishini;
5. Umsebenzi oyinhloko we-molybdenum disulfide esetshenziswa njengezinto zokungqubuzana ukunciphisa ukungqubuzana ezingeni lokushisa eliphansi, ukwandisa ukungqubuzana ezingeni lokushisa eliphezulu, nokunciphisa ukulahleka komlilo.
Ukusetshenziswa kwe-molybdenum disulfide (MoS2)
1. Ukugcoba ngaphansi kwezimo zokushisa ezibanzi: ububanzi obusebenzayo bamafutha okugcoba namafutha angaba ngu-60 ° C kuya ku-350 ° C. I-molybdenum disulfide lubricant eqinile ingasetshenziswa ku-Operating lokushisa ibanga ukusuka ku-270 ° C kuya ku-1000 ° C.
2. Ukugcoba ngaphansi kwezimo zomthwalo osindayo: ngokuvamile, ifilimu kawoyela yamafutha okugcoba namafutha angathwala umthwalo omncane kuphela. Uma umthwalo udlula inani elilinganiselwe ongalithwala, ifilimu kawoyela izophuka futhi indawo yokungqubuzana izoluma. Umthwalo omaphakathi ongawuthwala ifilimu yokugcoba eqinile ngu-108Pa.
3. Ukugcoba ngaphansi kwezimo ze-vacuum: ngaphansi kwezimo eziphezulu ze-vacuum, ukuhwamuka kwamafutha okugcoba kanye namafutha kukhulu kakhulu, okulula ukulimaza imvelo ye-vacuum futhi kuthinte ukusebenza kwezinye izingxenye. Izinto zokugcoba eziqinile ze-Molybdenum disulfide ngokuvamile zisetshenziselwa ukuthambisa.
4. Ukugcotshwa ngaphansi kwezimo zemisebe: Ngaphansi kwezimo zemisebe, izinto zokuthambisa eziwuketshezi ezivamile zizopholisa noma zibole futhi zilahlekelwe izici zazo zokuthambisa. Izithambisi eziqinile zinokumelana kahle nemisebe.
5. Ukugcotshwa kwendawo eshelelayo eqhutshwayo: Isibonelo, ukungqubuzana kwendawo eshelelayo eqhutshwayo, njengebhulashi likagesi lemoto kagesi, isilayidi esiqhutshwayo, indandatho yokuqoqa ilanga kusatellite yokwenziwa esebenza ku-vacuum kanye nokuxhumana kukagesi oshelelayo, kungagcotshwa ngezinto eziyinhlanganisela ezihlanganisiwe. i-carbon graphite noma insimbi.
6. Izimo ezinezimo zemvelo ezimbi kakhulu: Ezimweni ezinzima zemvelo, njengemishini yezokuthutha, imishini yobunjiniyela, izikhungo zemboni yensimbi nensimbi nensimbi, imishini yezimayini nezinye izingxenye zokudlulisa ezisebenza othulini, inhlabathi, izinga lokushisa eliphezulu kanye nomswakama kanye nezinye imvelo enokhahlo. Ezimweni, i-molybdenum disulfide lubricant eqinile ingasetshenziselwa ukuthambisa.
6. Imvelo Egqwalayo: Isibonelo, izingxenye ezidluliswayo zemishini yasolwandle nemishini yamakhemikhali zisebenza emanzini (isiphunga), emanzini olwandle, i-asidi, i-alkali, usawoti kanye nezinye izinto ezigqwalayo, futhi kufanele zibhekane namazinga ahlukene okugqwala kwamakhemikhali. I-molybdenum disulfide lubrication eqinile ingasetshenziselwa izingxenye zokudlulisela ezisebenza kulesi simo.
7. Izindawo ezinezimo zemvelo ezihlanzeke kakhulu: izingxenye zokudlulisela emishinini efana ne-electronics, izindwangu, ukudla, imithi, ukwenza amaphepha, ukuphrinta, njll. zidinga ukugwema ukungcola, futhi okokugcoba okuqinile kwe-MoS2 kungasetshenziswa ukuthambisa.
8. Izimo ngaphandle kokunakekelwa: ezinye izingxenye zokudlulisela azidingi ukulungiswa, kanti ezinye izingxenye zokudlulisela zidinga ukunciphisa izikhathi zokunakekela ukuze kongiwe izindleko. Kulezi zikhathi, ukusetshenziswa kwesithambiso esiqinile se-MoS2 kuyafaneleka, kulula futhi kungonga imali.
Izici ze-Molybdenum disulfide
