Krytox GPL 217極壓通用潤滑脂含二硫化鉬添加劑，100% 不燃，化學(xué)惰性，Krytox GPL217 重負(fù)荷潤滑脂用于高負(fù)載或低速。 Krytox GPL 217極壓通用潤滑脂在邊界和混合摩擦條件下具有高承載能力和良好的潤滑特性。 除了Krytox GPL 217極壓通用潤滑脂中的 EP 添加劑外，Krytox 油由于其在負(fù)載下的粘度增加和其獨(dú)特的摩擦化學(xué)特性，其本身作為油提供了足夠的 EP 保護(hù)。
Krytox GPL 217 Grease | Extreme Pressure General-Purpose Lubricants
Molybdenum Disulfide Additive, 100% Nonflammable, Chemically Inert
Krytox GPL 217 heavy-duty grease is used for high loading or slow speeds. EP greases have high load-carrying capability and good lubrication characteristics under boundary and mixed friction conditions. In addition to the EP additive in Krytox GPL 217 heavy-duty grease, Krytox oil provides adequate EP protection as an oil by itself, due to the viscosity build under load and its unique tribochemistry.
A common test for analyzing EP performance is the Timken EP method, ASTM D2509. The test is performed by applying pressure between a rotating steel cup and a steel block and simulates line contact conditions. Two conditions are observed; the OK Load is the highest load at which no seizing or welding occurs, and it also reflects the load-carrying capability of the lubricant. The Score Load is the lowest load at which seizing or welding is observed. The scar width, which is the average scar width at the load corresponding to the OK load valve, is also recorded.
