I-Grease Lubring ifanelekile kwizicelo eziphantsi zesantya eziphakathi apho iqondo lokushisa le-Ber lingaphantsi kweqondo lokushisa. Akukho grisi yokuthambisa i-fection ilungele zonke izicelo. Igrisi nganye inemisebenzi enqongopheleyo kunye neempawu. Igrisi iqulethe ioyile yesiseko, i-thi cokener kunye nezongeziweyo. Ukuthwala i-Geise ihlala iqulethe ioyile yesiseko se-petroleum ngesepha ethile yentsimbi. Kwiminyaka yakutshanje, i-organic kunye ne-rickainers kunye ne-inorganic yongezwa kwi-oils yesiseko se-oyile. Itheyibhile engama-26 ishwankathela ubume begrisi. Itheyibhile 26. Izithako ze-oyile ye-oyile i-oyile i-oyile ye-oyile ye-WHDROCROOR ye-Wilicoone i-oyile (i-aluminium, i-calcium, i-calcisum, i-ralbon, i-polycic) i-polyurea i-polyurea i-polyure I-Dye Tackimier Anti i-Antioxididant Anti-i-Geases egqwesileyo kunye ne-Alweminium-esekwe kwi-Aleminium egqwesileyo, ilungele izicelo zemizi-mveliso ekufuneka ithintele ukuntywila. I-lithium-esekwe kwi-lithium ineendlela ezininzi kwaye ilungele izicelo zemizi-mveliso kunye nebhetri yokuphela kwamavili.
Ioyile ye-Syntithotictictictictictictict, ezinjengee-esters, ii-ords ze-organic kunye neziliki, xa zisetyenziswa zizinto ezisetyenziswayo ezisetyenziswayo kunye nezilumkiso, elonaqondo lobushushu lihlala liphezulu kune-oils esekwe kwi-oils. Uluhlu lobushushu olusebenzayo lwegrisi yemikhwa inokuthi ivela kwi -73 ° C ukuya kwi-288 ° C. Oku kulandelayo ziimpawu ngokubanzi ze-thickeaners eziqhele ukusetyenziswa ngeoyile esekwe kwi-petroleum. Itheyibhile 27. Iimpawu ngokubanzi ze-thickeiners ezisetyenziswa kwi-oils ye-petroleum ejibilikayo iphosa i-tickocan yokuhlaselwa kwamaqondo aphantsi kwetafile

Ukusetyenziswa kwePolyurea njengoko i-thi checker yenye yezona zinto zibalulekileyo kwicandelo le-lebring ngaphezulu kweminyaka engama-30. I-Polyreaurea Igrisi ibonisa intsebenzo egqwesileyo kwizicelo ezahlukeneyo zengleqweni, kwaye ngexesha nje elifutshane, ithathelwe njengebhola ethathwa njengebhola. Iqondo lobushushu eliphantsi phantsi kweemeko zobushushu eziphantsi, i-torque yokuqala yegrisi ibaluleke kakhulu. I-Grease Geise inokusebenza kuphela xa i-ifutha iyasebenza, kodwa iya kubangela ukunganyangeki okukhulu ekuqaliseni kwengxokolo. Kwabanye oomatshini abancinci, isenokungaqali xa iqondo lobushushu liphantsi kakhulu. Kwimeko enjalo yokusebenza, kuyafuneka ukuba igrisi ineempawu zeqondo lobushushu eliphantsi liqala. Ukuba uluhlu lobushushu olusebenzayo lubanzi, igrisi yokwenziwa inezinto eziluncedo. Igrisi isenokwenza okokuqala kwaye isebenze i-torque encinci kwiqondo lokushisa eliphantsi le--73 ° C. Ngamanye amaxesha, ezi gqolo zisenza ngcono kunezihlunu malunga noku. Inqaku elibalulekileyo malunga negrisi kukuba i-torque ayisiyomfuneko ukuba ibe ngumsebenzi wokungaguquguquki okanye ukusebenza ngokubanzi. Ukuqala kwe-torque kungumsebenzi wentsebenzo yomntu ngamnye wegrisi ethile, kwaye igqitywe ngamava.
Iqondo lokushisa eliphezulu: Umda wobushushu obuphezulu wegreyithi yale mihla uhlala ungumsebenzi obanzi wozinzo we-thermal kunye nokunyangwa kwe-oxidation kwi-oyile kunye nokusebenza kwe-oxidation. Uluhlu lobushushu lwegrisi luzimisele indawo ephosakeleyo yegrisi kunye nokuqulunqwa kweoyile yesiseko. Itheyibhile 28 ibonisa uluhlu lobushushu lwegrisi phantsi kweemeko ezahlukeneyo zeoyile. Emva kweminyaka yokuvavanywa kweebherimitha ezityhafileyo, iindlela zawo ezinamandla zibonisa ukuba ubomi obutyalayo buya kuphawulwa yonke i-10 ° Cuk 'iqondo lobushushu. Umzekelo, ukuba inkonzo yobomi yegrisi kwiqondo lobushushu engama-90 ° C liiyure ezingama-2000, xa iqondo lobushushu linyuka ukuya kwi-100 ° C, inkonzo incitshisiwe ukuya kwi-1000 iiyure. Kwelinye icala, emva kokuthoba ubushushu ukuya kwi-80 ° C, ubomi benkonzo kulindeleke ukuba bafikelele kwiiyure ezingama-4000.
