A dimercaptothiadiazole dimer containing ester groups was synthesized,and its tribological performance as the antiwear additive of 12-hydroxystearate lithium grease was evaluated on a four-ball tester and the friction surface of the steel ball after test was also investigated by X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM) and energy dispersive spectroscope(EDS).
合成了含酯基的二巯基噻二唑二聚物,采用四球试验机考察了其在12-羟基硬脂酸锂基脂中作为极压抗磨剂的摩擦学性能,并采用XPS、SEM和EDS分析了摩擦表面的特性。
A method for estimating the two wave numbers of an ester group is discussed based on a multiple-repression analysis This estimation was achieved by assuming that there is additivity in the effect of adjacent groups Both the low and high wave numbers were predicted for a standard deviation of 6 31cm -1 and 4 25cm -
