WitrynaCorrosive sulphur has been commonly regarded as an enormous threat to electrical power equipment in recent decades. Cuprous sulphide (Cu2S) deposition on the insulating oil and paper insulation caused by sulphur corrosion will bring about insulation de-teriorations or failures in power transformers and shunt reactors. A large number of WitrynaSulfur-Phosphorus EP Additives and Naturally Occurring Sulfides. Many sulfur-phosphorus EP additives thermally decompose at 250°C to 275°C and again will readily pass the copper strip corrosion test. ... On the downside, they are corrosive to certain metal and metal alloys, particularly yellow metals, which contain copper as a major …
Sulfur in Water: How Does it Get There and How Can I Fix It?
WitrynaCorrosive sulfur has been found in numerous mineral insulating oils. Adsorption is a promising method to remove the corrosive sulfur in insulating oil. In this paper, three types of adsorbents, CeY, CuY, and AgY, were prepared with liquid-phase ion exchange. The adsorbents were characterized by X-ray fluorescence, X-ray photoelectron ... Witrynasulfuric acid, sulfuric also spelled sulphuric (H2SO4), also called oil of vitriol, or hydrogen sulfate, dense, colourless, oily, corrosive liquid; one of the most commercially important of all chemicals. Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination … lava patio heater cover
