Embodiment Construction
[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0024] An electrochemical method for measuring the oxidation induction time of grease, the steps are as follows, (1): the glassy carbon electrode is successively filled with 0.3 and 0.05 μm Al 2 o 3 The powder is ground on the buckskin until the electrode surface is as bright as a mirror. Sonicate with absolute ethanol and ultrapure water for 5 min in turn, and dry at room temperature for later use. (2): Place the treated glassy carbon electrode in 1.0g / L graphene, 0.05mol / L NaCl suspension, pass N 2 Deoxygenation. The saturated calomel electrode was used as the reference electrode, and the platinum sheet electrode was used as the counter electrode. Using cyclic...
