"Isitshalo sethu sicabanga ngokushintsha igrisi ye-lithium-complex iye kugrisi ye-polyurea ukuze sigcobe izingxenye eziningi zomshini wethu. Ingabe zikhona izinzuzo noma ukungalungi ekusebenziseni igrisi ye-polyurea phezu kwe-lithium-complex grease uma zonke ezinye izici zilingana? "

Uma uqhathanisa igrisi ye-polyurea negrisi ye-lithium-complex, i-drawback enkulu ukuthi ama-polyurea thickeners awahambisani neze.Lokhu kungahambisani kungabangela ukuqina noma ukuthamba kwamafutha.

Ukuthambisa amafutha kungaholela ezinkingeni ezimbalwa, njengokungavumeli ukugcotshwa okufanele kwama-roller.Amafutha engeziwe kumelwe abe esenezelwa ukuze kugcinwe ukuthambisa okufanele kuze kube yilapho ingxube engahambelani iyasuswa.

Ukuqina kwamafutha kungaholela ezinkingeni ezimbi nakakhulu, njengoba amafutha angasakwazi ukugeleza emgodini wokuthwala, okushiya i-bearing ilambile ukugcotshwa.

Kodwa-ke, izingqimba ze-polyurea zinikeza izinzuzo ezithile ngaphezu kokuqina kwe-lithium.Isibonelo, amafutha e-polyurea ngokuvamile ayinketho ekhethwayo yezinhlelo zokusebenza ezivaliwe impilo yonke.Leziamafuthabavame ukuba namazinga okushisa aphezulu okusebenza, izakhiwo ze-antioxidative ezingokwemvelo, eziphezuluukuzinza okushisayonezici zokopha okuphansi.

Futhi banephuzu lokwehla elicishe libe ngu-270 degrees C (518 degrees F).Ukwengeza, njengoba ukwakheka kwawo kungasekelwe kukuqina kwensipho yensimbi njengamafutha e-lithium, angashiya inhlabathi emanzi uma isiphelile, ngokuvamile ayinketho ekhethwayo yokugcotshwa kwamamotho kagesi.Ngokwesilinganiso, amafutha e-polyurea angaba nempilo engcono ephindwe kathathu kuya kahlanu kunamafutha asuselwa ku-lithium.

Ngakolunye uhlangothi, i-lithium complex iwugqinsi oluvame kakhulu emakethe, enza cishe amaphesenti angama-60 amafutha atholakala eNyakatho Melika.Izibalo zokusebenzisana zibonisa ukuthi kunoxhaxha olukhulu lwezinto ezijiyayo lapho izingqimba ze-lithium-complex ezifakazele ukuthi ziyahambisana.

Zibuye ziyikhethelo eliyinhloko le-thickener kubakhiqizi abaningi bemishini.Amafutha e-lithium-complexngokuvamile zinikeza ukuzinza okuhle, izici zokushisa okuphezulu kanye nezakhiwo ezithile zokumelana namanzi.

Womabili amafutha e-polyurea kanye ne-lithium-complex anezinzuzo kanye nokubi, ngakho-ke qiniseka ukuthi uhlola ukuhambisana kanye ne-viscosity yomkhiqizo ngamunye kuqala.

I-polyurea thickeners ingaba yinzuzo ezindaweni ezimanzi nasezintweni lapho aimpilo ende yamafuthakulindeleke.I-Extreme-pressure (EP)kanye nezithasiselo ze-antioxidant zingase zihlanganiswe ukuze kusize ukuzuza impilo ende kanye nokwethembeka kwemishini.

Yiqiniso, ukusetshenziswa kanye nezici ezifiselekayo zamafutha zizoba nomthelela wokuthi iyiphi i-base thickener okufanele isetshenziswe.
