Kedu ihe bụ molybdenum disulfide?
Molybdenum disulfide (MoS2) bụ mmanụ mmanu siri ike dị mkpa, nke a maara dị ka "eze mmanu siri ike"
1. Molybdenum disulfide bụ ntụ ntụ siri ike nke sitere na molybdenum na-etinye ntụ ntụ mgbe emechara kemịkal.
2. Agba nke ngwaahịa ahụ bụ oji na obere ọlaọcha na-acha ntụ ntụ, na-egbuke egbuke dara, ọ na-adịkwa ka ọ na-amị amị mgbe a na-emetụ ya aka, ọ na-esikwa ike na mmiri.
3. Ngwaahịa ahụ nwere uru nke mgbasa ozi ọma na enweghị njikọ.Enwere ike ịgbakwunye ya na griiz dị iche iche iji mepụta steeti colloidal na-adịghị ejikọta, na-abawanye mmanu na oke nrụgide nke griiz;
4. Ọ dịkwa mma maka okpomọkụ dị elu, nrụgide dị elu, nnukwu ọsọ na nnukwu ibu ọrụ ọnọdụ ọrụ, na-agbatị ndụ ọrụ nke akụrụngwa;
5. Ọrụ bụ isi nke molybdenum disulfide nke a na-eji dị ka ihe mgbagwoju anya bụ iji belata esemokwu na obere okpomọkụ, na-abawanye esemokwu na okpomọkụ dị elu, ma belata nkwụsị ọkụ.
Ngwa nke molybdenum disulfide (MoS2)
1. Lubrication n'okpuru ọnọdụ okpomọkụ dị iche iche: ihe dị iche iche nke mmanụ na-egbuke egbuke na mmanụ griiz dị ihe dị ka 60 ° C ruo 350 Celsius C. Molybdenum disulfide siri ike mmanu nwere ike tinye n'ọrụ okpomọkụ nso si 270 ° C ka 1000 ° C.
2. Lubrication n'okpuru ọnọdụ ibu dị arọ: n'ozuzu, ihe nkiri mmanụ nke mmanụ mmanụ na mmanụ griiz nwere ike iburu obere ibu.Ozugbo ibu ahụ gafere oke oke ọ nwere ike iburu, ihe nkiri mmanụ ga-agbaji ma elu esemokwu ahụ ga-ata.Nkezi ibu nke ihe nkiri mmanye siri ike nwere ike ibu bụ 108Pa.
3. Lubrication n'okpuru ọnọdụ oghere: n'okpuru ọnọdụ ikuku dị elu, evaporation nke mmanụ lubricating mmanụ na griiz dị ntakịrị, nke dị mfe imebi ebe ikuku na-emetụta ọrụ ọrụ nke ihe ndị ọzọ.A na-ejikarị molybdenum disulfide ihe na-ete mmanụ siri ike maka mmanu mmanu.
4. Lubrication n'okpuru ọnọdụ radieshon: N'okpuru ọnọdụ radieshon, n'ozuzu mmiri mmiri lubricants ga-polymerize ma ọ bụ decompose na-atụfu ha lubricating Njirimara.Ihe mmanu siri ike nwere ezigbo nguzogide radieshon.
5. Lubrication nke conductive sliding elu: Dị ka ihe atụ, esemokwu nke conductive sliding elu, dị ka electric ahịhịa nke electric moto, conductive mmịfe, anyanwụ na-anakọta mgbanaka na wuru satịlaịtị na-arụ ọrụ na agụụ na sliding eletriki kọntaktị, nwere ike lubricated na ihe mejupụtara ihe mejupụtara. nke carbon graphite ma ọ bụ metal.
6. Ọnọdụ na ọnọdụ gburugburu ebe obibi jọgburu onwe ya: N'ọnọdụ ọnọdụ gburugburu ebe obibi siri ike, dị ka igwe ụgbọ njem, igwe injinia, ụlọ ọrụ ụlọ ọrụ metallurgical na ígwè na nchara, igwe Ngwuputa na akụkụ ndị ọzọ na-ebufe na-arụ ọrụ na uzuzu, sedimenti, oke okpomọkụ na iru mmiri na gburugburu ebe obibi ndị ọzọ siri ike. Ọnọdụ, molybdenum disulfide siri ike mmanu nwere ike iji maka mmanu mmanu.
6. Ebe na-emebi emebi: Dịka ọmụmaatụ, akụkụ nnyefe nke igwe mmiri na igwe kemịkalụ na-arụ ọrụ na mmiri (steam), mmiri mmiri, acid, alkali, nnu na mgbasa ozi ndị ọzọ na-emebi emebi, na ha ga-enwerịrị ogo dị iche iche nke corrosion chemical.Enwere ike iji molybdenum disulfide siri ike lubrication maka akụkụ nnyefe na-arụ ọrụ n'ọnọdụ a.
7. Ebe nwere ọnọdụ gburugburu ebe obibi dị ọcha: akụkụ nnyefe na igwe dị ka ngwá electronic, textiles, nri, ọgwụ, ime akwụkwọ, mbipụta, wdg kwesịrị izere mmetọ, na MoS2 ike mmanu nwere ike iji mmanu mmanu.
8. Ọnọdụ na-enweghị mmezi: ụfọdụ akụkụ nnyefe adịghị mkpa nrụzi, na ụfọdụ akụkụ nnyefe kwesịrị ibelata oge mmezi iji chekwaa ego.N'oge ndị a, iji MoS2 lubricant siri ike bụ ihe ezi uche dị na ya, dị mma ma nwee ike ịchekwa ego.
