Use of stellite to prevent silver plateout |
摘要 |
The present invention is the use of stellite material for all contact surfaces between moving parts and a metering pump pumping silver photographic emulsion. All parts that are in contact with the solutions containing silver made of stellite will prevent failure of rotating assemblies due to metallic silver plateout between rotating parts. Prior art pumps exhibited silver plateout after very few hours of operation.
