Mafuta oyambira amafuta okwera kwambiri
PAG yamafuta okwera kwambiri
Ukhondo wapadera wa mankhwala a PAG, zinthu zawo zowonongeka zimatha kusungunuka m'mafuta odzola ndipo sizingapange mafuta, filimu ya carbon deposit ndi mwaye.
Malo otentha kwambiri ndi malo ong'anima, amalimbikitsa kugwiritsidwa ntchito pansi pa 200 ℃ kwa nthawi yayitali.
Ntchito yabwino yamafuta okhala ndi anti-oxidant ndi antirust yomwe imagwiritsidwa ntchito nthawi zonse mumakampani osindikiza nsalu ndi utoto.
Mapangidwe apadera osungunuka m'madzi ndi mawonekedwe oyeretsedwa amatha kupewa kufooka, monga sinkhole pamwamba pa filimu.
Kutentha koyenera kumatha kufika ku 220 ℃, komwe kumagwiritsidwa ntchito kwambiri pamagalimoto amagalimoto.
Kawopsedwe wochepa wa PAG atha kugwiritsidwa ntchito pamakina olumikizana ndi chakudya.
Low mamasukidwe akayendedwe PAG ndi biodegradable.

Synthetic esters yamafuta okwera kwambiri
Gwiritsani ntchito dipentyl alcohol ester ndi polybasic acid ester ngati mafuta oyambira, omwe amagwiritsidwa ntchito pakati pa 250-300 ℃.
Kuchita bwino kwambiri kwa kutentha kwapamwamba, kuchepa pang'ono kwa coking ndi evaporation.
Good detergency ndi kubalalitsidwa, coking bolodi ndi woyera.
Pogwiritsira ntchito kukhudzana wamba chakudya, tilinso angapo mankhwala amalangiza.
