Porous Polyimide Oily Material

ZYS has the strong independent research and development ability, grasps core technology of the porous polyimide oily cage and material, and has successfully developed and applied in more than 150 kinds of bearing models. Annual batch production of porous polyimide oily cage and material is nearly 30,000 pieces.

Description

Features of Porous Polyimide Oily Material:

Porous Polyimide Oily Material is made of polyimide as matrix, modified by solid lubricating material, and formed by pressure-pressing and sintering. Porous Polyimide Oily Material has interpenetrating microporous materials, and then it is cleaned by ultrasonic and dried in vacuum. Finally, the porous oil cage or oil holder is made by vacuum immersion at a certain temperature. Porous Polyimide Oily Material has the advantages of high mechanical strength, excellent tribological properties, adjustable and controllable micropore properties, aging resistance, good temperature adaptability and compatibility of lubricating oil.

Lubrication mechanism of Porous Polyimide Oily Material:

The porous polyimide cage can adsorb or release lubricating oil according to the change of bearing operating condition, establish dynamic balance, improve the lubricating life of bearing, and meet the requirement of long life, high precision and high reliability of aerospace bearing.

Application of Porous Polyimide Oily Material:

Porous Polyimide Oily Material is mainly used for special bearing for space long-life high-precision inertial navigation system, including gyroscope bearings, satellite momentum wheel bearings and navigation platform bearings. At present, the gyro motor bearings with the longest life, the highest precision and the best performance in China are produced by ZYS and successfully applied in the fields of aviation, aerospace and ships. This product and technology is in the international advanced level. ZYS has the strong independent research and development ability, grasps core technology of the porous polyimide oily cage and material, and has successfully developed and applied in more than 150 kinds of bearing models. Annual batch production of porous polyimide oily cage and material is nearly 30,000 pieces.
