Amafutha esisekelo kanye nezithasiselo zamafutha okugoqa
I-ester ehlukile inciphisa ukungqubuzana endaweni ye-rlling seam futhi iqinisekise ukuhlanzeka kokudonsa.
Nciphisa i-iron powder kanye nokuguga kwendawo yensimbi, gwema ukonakala kwendawo.
I-ester eyinkimbinkimbi inikeza ukuthambisa okuhle kakhulu.
Indawo yokusebenza enempilo.Umsindo ophansi, ukushaqeka okuncane, ukunciphisa ukusetshenziswa, konga amandla, ukunciphisa izindleko ezigcinwe nempilo ende yesevisi -
Isengezo se-lubricity soketshezi olusebenzayo lwensimbi
I-Ester Series yoketshezi olusebenzayo lwensimbi:
Ama-Monoesters, ama-diesters kanye nama-polyol esters ama-fatty acids asetshenziswa kuketshezi olusebenzayo lwensimbi eyisisekelo ukuze kwehliswe ukungezwani kwendawo
phakathi kwamafutha nensimbi, kunikeza amandla amahle okuphuma kwamanzi.Oketshezini olusebenzayo lwensimbi olusekelwe emanzini, lwalusetshenziselwa ukuncibilikisa uwoyela futhi ilethe i-EP nesikhiphi sokugqwala.
Izithasiselo zikawoyela ezinjinini:
Ama-ester e-polymeric akhethekile anezici ezinhle kakhulu zokwenza ifilimu anikeza injini nowoyela wokudlulisela amandla okuthuthukisa ukusebenza kahle.

Isengezo samafutha okusebenza ensimbi
PAG quenching medium:
I-high viscosity water soluble PAG, lawula ijika lemingcele yokupholisa ngokulungisa isisindo se-molar kanye nokugxila kwe-polymer.
Uketshezi olucacile nomkhiqizo wombala okhanyayo wenza kucace futhi kube sobala umkhiqizo wokugcina.
Impahla yokuhlanza enhle kakhulu, elungele ukuhlanza i-workpiece ngemuva kokucisha.
Isengezo samafutha okucima:I-polymer ephezulu ye-molecular inikeza ukukhanya okuhle kakhulu kwe-workpiece ecishiwe.
I-viscous liquid esobala, asikho isidingo sokushisa, kulula ukuyisebenzisa.
Iphoyinti elikhanyayo eliphakeme, impilo ende, umthamo ophansi, ulungele uwoyela ogqamile, uwoyela wokucisha ukushesha, ukutusa okukhethekile ukuthi kusetshenziswe kuwoyela wokucisha i-isothermal. -
Uwoyela wesisekelo wezinjini zezimoto nokuhanjiswa
I-PAG yezinjini zezimoto nokudluliswa
Njengesisekelo samafutha enjini yokwenziwa, i-PAG inokuhlakazeka okuvelele, ukuhlanzeka okunikeza ukuzinza okuhle kakhulu kwezinga lokushisa eliphezulu, ukuthambisa kanye nokushisa okuphansi kwezinga lokushisa.
I-low friction coefficient ingathuthukisa ukonga kukaphethiloli futhi ivikele ukungqubuzana kangcono.
I-ester yokwenziwa yezinjini zezimoto nokuhanjiswaI-Esterification ngokuphelele i-polyol ester ne-diesters, ukuhlanzeka okuphezulu.
Chaza i-fatlute yamafutha amaminerali kanye ne-PAO ngaphansi kokushisa okuphezulu, ukunciphisa idiphozi nefilimu.
I-viscosity yezinga lokushisa eliphansi elihle kakhulu i-CCS ingathuthukisa ikhono lokuqala ezingeni lokushisa eliphansi.
Ukuzinza okuvelele kwe-anti-oxidation kanye nokuhlakazeka okuhlanzekile kuletha impilo ende yesevisi. -
Amafutha ayisisekelo okugcoba
Isisekelo samafutha okugcoba:
I-ester yokuhlanzeka okuphezulu, ukuthambisa okuhle nokuncibilika
I-biodegradable futhi ivuseleleke, Hlangana nezinga lokuthintana nokudla
Njengoba ithwele izinga lokushisa elidlulele, gcina ukuhwamuka okuphansi kokulahleka kumazinga okushisa aphezulu futhi ungabi yiqhwa ezingeni lokushisa eliphansi
I-PAG ehlukahlukene ingasetshenziswa njengamafutha ayisisekelo wegrisi ukuthuthukisa ukuthambisa kanye nempahla ephansi yokushisa. -
Uwoyela wesisekelo wamafutha weketanga lokushisa eliphezulu
I-PAG yamafutha weketanga lokushisa eliphezulu:
Izinga lokushisa elifanele lingafinyelela ku-220 ℃, lisetshenziswa kabanzi embonini yezimoto.
Ama-ester okwenziwa kuwoyela weketanga lokushisa eliphezulu:Sebenzisa i-dipentyl alcohol ester ne-polybasic acid ester njengowoyela wesisekelo, osetshenziswa phakathi kuka-250-300℃.
