I-graphite grease kanye nokusetshenziswa kwayo ezimotweni
Okuqukethwe
Amafutha egreyidi - i-lubricant ye-inorganic futhi, emnyama noma emnyama ngombala, enokuqina nokuvumelana kwe-viscous. Ngaphandle, ifana namafutha aziwayo. I-lubricant yenziwa ngesisekelo samafutha emifino kusetshenziswa uketshezi lwamafutha e-petroleum cylinder kanye nensipho ye-lithium noma ye-calcium, kanye ne-graphite. I-graphite powder isetshenziswa njengeyakamuva. Ngokuhambisana ne-GOST 3333-80, ngokusho okukhiqizwa ngayo, izinga lokushisa elilungile lokusetshenziswa lisuka ku-20 ° C kuya ku-60 ° C, nokho, empeleni, lingakwazi ukumelana namazinga okushisa abucayi nakakhulu. I-Graphite grease isetshenziswa kakhulu embonini, kanye nasekuthuthweni komshini. okungukuthi, igcotshwe nge-spring, i-suspension elements, ama-bearings alayishwe kakhulu, amagiya avulekile, njalonjalo.
Ukwakhiwa kwe-lubricant ye-graphite
Okokuqala, udinga ukwazi ukuthi ezincwadini zobuchwepheshe, igama elithi "i-graphite lubricant" lingasho izingoma ezihlukahlukene. Iqiniso liwukuthi ekuqaleni le ncazelo ibhekisela ku-lubricant ye-inorganic, lapho i-graphite isetshenziswa njenge-thickener, kodwa ngomqondo obanzi, izinto zokugcoba nazo zibizwa kanjalo, lapho i-graphite isetshenziswa njengesengezo. Ngakho, igama elithi "graphite lubricant" lingasho:
i-graphite echotshoziwe
- i-graphite powder evamile, engasetshenziswa njengento yokugcoba eqinile;
- insipho-based lubricant equkethe graphite;
- ukumiswa kwegraphite kusisombululo samafutha (i-inorganic type lubricant).
Ukwakhiwa kokugcina okuvame ukubizwa ngokuthi i-graphite grease, futhi kusazoxoxwa ngakho. Ubuchwepheshe bayo bokukhiqiza buhlanganisa ukujiya uwoyela we-viscous organic noma wokwenziwa, otholakala emikhiqizweni ye-petroleum, ngensipho ye-calcium ne-graphite powder. Ngamanye amazwi, singasho ukuthi i-graphite powder yengezwa kugrisi yakudala, enikeza i-lubricant izakhiwo zayo.
Njengamanje, amafutha e-copper-graphite nawo angatholakala endalini. I-powder yethusi yengezwa ekubunjweni kwayo. Iyakwazi ukumelana namazinga okushisa aphezulu. Ngokuvamile amafutha e-copper-graphite atholakala ngendlela yama-aerosols. Uma sibheka phambili, ake sithi ngokuvamile lokhu kwakheka kusetshenziselwa iziqondiso ze-caliper. Ngale ndlela ungagwema ukunamathisela ama-disc kanye / noma izigubhu zamabhuleki kuma-hub flanges.
Izici ze-graphite grease
Ngokwayo, i-graphite iqhuba ukushisa nogesi kahle, ayiwi ngaphansi kwethonya lomswakama, ayithinteki ugesi we-static, futhi iphinde ibe ne-thermal stable (ingakwazi ukumelana nokushisa okuphezulu). Zonke lezi zakhiwo, nakuba ngezinga elincane, zinento yokugcoba ehambisanayo.
Iyini i-lubricant ye-graphite enhle? Izinzuzo zayo zihlanganisa:
- ukumelana kwamakhemikhali (uma usebenzisa i-lubricant ezindaweni zokusebenza, izakhi zayo azifaki ukusabela kwamakhemikhali nalo);
- ukumelana nokushisa (akuguquki kuze kufike ku-+150 ° C, njengoba ukuhlushwa kwezinto eziguquguqukayo ekubunjweni kwayo kuncane, akulahlekelwa izici zayo zokusebenza emazingeni okushisa aphezulu);
- ivikela izindawo zokusebenza kumswakama;
- kwandise ukuzinza kwe-colloidal;
- ukuvimbela ukuqhuma;
- inezinto ezinhle kakhulu zokugcoba;
- kwandisa ukumelana nokugqoka, ukusebenza kwemishini kanye nempilo yesevisi yendlela lapho isetshenziswa khona;
- kunciphisa inani lokubanjwa;
- engathinteki ngamafutha, okungukuthi, ihlala phezulu ngisho noma ikhona;
- igrisi ye-graphite inamathela kahle kunoma iyiphi indawo;
- ukumelana nogesi omile;
- inezindawo zokunamathela eziphezulu kanye ne-antifriction.
futhi enye inzuzo ebalulekile graphite grease yayo intengo ephansi ngokusebenza okwanelisayo. Nakuba, ngobulungisa, kufanele kuqashelwe ukuthi okwamanje kukhona amanye ama-lubricant amaningi athuthuke kakhulu, okuthi, nakuba ebiza kakhulu, asebenza kangcono.
Nokho, amafutha e-graphite nawo anemibi. okungukuthi, ayikwazi ukusetshenziswa ezindleleni ezinokunemba okuphezulu, njengoba ukungcola okuqinile okukhona ku-graphite kuzofaka isandla ekwandeni kokuguga kwezingxenye;
