اکسیداسیون و آزمایش روغن‌های توربین

Ten peer-reviewed papers cover the latest industry trends on suffering points, evolving lubricant /antioxidant additive technologies, and changing equipment designs and operating conditions, with a focus on how these factors impact oxidation. It addresses how to improve current ASTM bench tests used as predicative tools for measuring oxidative degradation, including: D 943 Oxidation Characteristics of Inhibited Mineral Oils; D 4310 Sludge Tendency; D 2272 Oxidation Stability of Steam Turbine Oils by Rotating Pressure Vessel. STP 1489 is a valuable resource to those in the lubricant and turbine industry, including original equipment manufacturers, end users, lubricant producers, lubricant additive suppliers, test equipment manufacturers, and standard test method developers.
