The testing result is that the mass concentration of YHCZ of FCC diesel fuels was decreased from 3.571 mg/100 mL to 1.257 mg/100 mL which indicates that phenol compounds has dramatic effects on the oxidation stability of diesel fuels.
The lab high-low temperature property, oxidation stability, high temperature detergency, low-temperature sludge, wear screeningtest, L-38 bearing corrosion, MS-sequence ll D, Ⅲ D, Ⅴ: D and Cat 1G2, and standard engine platformevaluation test showed that the quality of 10W/40 SF/CD grade internal combustion oil met the specification of API SF and CD oil.
By adopting rotary bomb oxidation test(RBOT),pressurized differential scanning calorimeter(PDSC) and other methods,the improving effects on oxidative stability of six kinds of lubricating base oil with five kinds of phenolic antioxidants were studied.
After the comprehensive assessment on indoor physiochemical performances, it is found that the research oil possesses such advantages as, low solidifying point, oxidation invariability and excellent performances as, defoaming, anti-emulsification, anti-rusting and anticorrosion.
Thermal and Thermal-Oxidation Stability of Permethylpolysilane-Siloxanes and Permethylpolyoxysilane
Thermal and thermal-oxidation stability of organosilicon copolymers with linear or/and cyclic oligosilane fragments in the backbone was studied by thermal gravimetric analysis in an inert gas and in air.
The results of this prediction were analyzed, and the reasons for differences in the oxidation stability of the samples examined were established.
The oxidation stability of filled polypropylene measured by the oven method showed lower values in the case of serpentinite filled polypropylene.
Because of the presence of eleostearic acid, which is a main component of tung oil, the oxidation stability as determined by the Rancimat method was very low, 0.5h, but the cold filter plugging point, -11 °C, was good.
