The gas spring can be coated with solid lubricating material on the sealing ring in the dynamic seal. Solid lubrication is to separate the two surfaces in dynamic contact with solid powder or coating to reduce friction. What is the role of lubrication in nitrogen gas spring solids?
1. Five poisons, economy, and simple process. The materials used for solid lubrication of mold nitrogen springs include layered objects (molybdenum disulfide, tungsten diselenide, graphite, tungsten disulfide, etc.), polymers (polytetrafluoroethylene, polytrifluoroethylene, polyvinyl fluoride, nylon) , Other inorganic compounds, etc. Graphite, molybdenum disulfide and polytetrafluoroethylene are mostly used today. Among them, molybdenum disulfide has better performance in the application of mold nitrogen springs, and can maintain a low friction coefficient during the working process of mold nitrogen springs, and the friction coefficient decreases with the increase of sliding speed and load.
2. The friction between the friction surfaces is small and stable and controllable;
3. The chemical composition is stable within the working temperature range of the mold nitrogen spring, and there is no corrosion to the bearing material;
4. Sticking firmly on the friction surface will not fall off quickly;
5. It has a certain degree of wear resistance and can maintain a long life;
