Development trend of new composite mechanical seal materials
2017-02-15
The more and more stringent requirements for
mechanical seal materials make it have some contradictory properties, and a single material is often difficult to meet. Combining some materials with different properties, learning from each other's strengths, and developing new composite materials, obviously represents the development trend of Ruo sealing materials. The current development trend of new composite mechanical seal materials is roughly as follows:
(1) Develop a composite sealing material whose strength is comparable to that of steel, but must have elasticity;
(2) A fiber-reinforced composite sealing material that can be heat-resistant above 500°C for a long time, and whose strength is above 1000MPa, and is easy to machine;
(3) Developed a resin-based fiber-reinforced composite sealing material that exceeds aluminum alloy in mechanical and heat resistance and can be plastically processed;
(4) Develop materials with high hardness and low brittleness;
(5) Develop materials that are stronger than steel, more elastic than rubber, and weldable;
(6) Develop new ceramic materials reinforced by fibers. 268.html,
