Menene molybdenum disulfide?
Molybdenum disulfide (MoS2) wani muhimmin mai mai mai ƙarfi ne, wanda aka sani da “sarkin m lubrication”
1. Molybdenum disulfide ne m foda sanya daga halitta molybdenum maida hankali foda bayan sinadaran tsarkakewa.
2. Launin samfurin baƙar fata ne kuma ɗan ƙaramin azurfa mai launin toka, tare da ƙyalli na ƙarfe, kuma yana jin zamewa idan an taɓa shi, kuma ba ya narkewa cikin ruwa.
3. Samfurin yana da fa'idodin tarwatsawa mai kyau da rashin ɗauri. Ana iya ƙarawa zuwa nau'i-nau'i daban-daban don samar da yanayin colloidal maras ɗauri, ƙara lubricant da matsananciyar matsa lamba na maiko;
4. Har ila yau, ya dace da yanayin zafi mai zafi, matsa lamba, babban sauri da yanayin aiki na inji, kuma yana kara tsawon rayuwar sabis na kayan aiki;
5. Babban aikin molybdenum disulfide da aka yi amfani da shi azaman kayan juzu'i shine don rage juzu'i a ƙananan zafin jiki, ƙara haɓaka a babban zafin jiki, da rage asarar ƙonewa.
Amfani da molybdenum disulfide (MoS2)
1. Lubrication a ƙarƙashin yanayin zafi mai faɗi: kewayon da ake amfani da shi na lubricating mai da mai yana kusan 60 ° C zuwa 350 ° C. Molybdenum disulfide m mai mai ana iya amfani da shi zuwa kewayon zafin aiki daga 270 ° C zuwa 1000 ° C.
2. Lubrication a ƙarƙashin yanayin nauyi mai nauyi: gabaɗaya, fim ɗin mai na mai mai mai da mai zai iya ɗaukar ƙaramin nauyi kawai. Da zarar nauyin ya wuce iyakar ƙimar da zai iya ɗauka, fim ɗin mai zai karye kuma saman ya ciji. Matsakaicin nauyin da ingantaccen fim ɗin mai zai iya ɗauka shine 108Pa.
3. Lubrication a ƙarƙashin yanayi mara kyau: a ƙarƙashin yanayin yanayi mai girma, ƙawancen man fetur da man shafawa yana da girma sosai, wanda yake da sauƙi don lalata yanayin yanayi kuma yana rinjayar aikin aiki na sauran sassan. Molybdenum disulfide m kayan shafa mai gabaɗaya ana amfani dashi don lubrication.
4. Lubrication a ƙarƙashin yanayin radiation: A ƙarƙashin yanayin radiation, masu amfani da ruwa na gabaɗaya za su yi polymerize ko bazuwa kuma su rasa kayan shafawa. M man shafawa suna da kyau radiation juriya.
5. Lubrication na conductive zamiya surface: Alal misali, gogayya na conductive zamiya surface, kamar lantarki goga na lantarki motor, conductive darjewa, hasken rana mai tara zobe a wucin gadi tauraron dan adam aiki a cikin injin da zamiya lantarki lamba, za a iya lubricated tare da hada kayan hada. na carbon graphite ko karfe.
6. Abubuwan da ke da mummunan yanayin muhalli: A cikin yanayi mai tsanani na muhalli, irin su kayan sufuri, injiniyoyin injiniya, masana'antun masana'antu na ƙarfe da ƙarfe da ƙarfe, injin ma'adinai da sauran sassan watsawa da ke aiki a cikin ƙura, laka, zafi mai zafi da zafi da sauran mummunan yanayi. yanayi, molybdenum disulfide m man shafawa za a iya amfani da man shafawa.
6. Muhalli mai lalacewa: Misali, sassan watsa kayan aikin ruwa da injinan sinadarai suna aiki a cikin ruwa (steam), ruwan teku, acid, alkali, gishiri da sauran hanyoyin lalata, kuma dole ne su sami digiri daban-daban na lalata sinadarai. Molybdenum disulfide m lubrication za a iya amfani da su watsa sassa aiki a cikin wannan halin da ake ciki.
7. Wuraren da ke da tsabtataccen yanayin muhalli: sassan watsawa a cikin injina kamar kayan lantarki, yadi, abinci, magani, yin takarda, bugu, da dai sauransu suna buƙatar guje wa gurɓataccen gurɓataccen gurɓataccen ruwa, kuma ana iya amfani da mai mai ƙarfi na MoS2 don lubrication.
8. Halittu ba tare da kulawa ba: wasu sassan watsawa ba sa buƙatar kulawa, kuma wasu sassan watsawa suna buƙatar rage lokutan kulawa don adana farashi. A cikin waɗannan lokatai, amfani da MoS2 mai mai mai ƙarfi yana da ma'ana, dacewa kuma yana iya adana kuɗi.
