Due to the requirements of special production processes, some key equipment of industrial and mining enterprises operates under extremely harsh working conditions. Due to heavy equipment, high ambient temperature, large dust or acid corrosion gas CO, SO2 and so on in the air, the lubrication of the equipment brings many problems, friction and wear are serious, most of the above domestic enterprises still use traditional oil, grease lubrication, and in fact, these industrial and mining conditions have exceeded the scope of oil and grease lubrication, it is easy to occur bearing and other friction pairs bite or bite to death, causing serious parts wear and damage, often leading to equipment shutdown.
In order to produce continuous operation, in addition to the original design requiring the installation of multiple equipment rotations, a large number of maintenance personnel must be invested. Severely limiting the increase in productivity, spare parts and energy consumption is extremely large, which has become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other enterprises have put forward the requirements for providing special lubrication materials under complex working conditions.
To this end, the research on embedded self-lubricating composite materials highlights its own characteristics in material formula and preparation process, and the material performance has reached the international advanced level, which solves the lubrication problem under special working conditions for enterprises and brings obvious economic and social benefits. However, due to a variety of reasons, more domestic enterprises have not yet adopted, and the above situation still exists.
