Paint metal surface pre-treatment technology

Surface nanocrystallization of great value, etc., but also in the preparation of more complex structure of the composite technology will play a huge role.

JS series of metal with a plastic composite white lubricating materials (I) U-like materials) is a multi-larvae L steel back bronze surface of a filled polymer composition of the metal plastic multi-layer self-lubricating material, which combines the advantages of metal and plastic, with high mechanical strength (static Heda 140MPa), good thermal conductivity, thermal expansion coefficient, low friction coefficient, good wear resistance and wide temperature range (a 200cc ~ +280 ℃), etc., can be used in a long time under dry friction . Slide in oil lubrication better performance. JS series self-lubricating composite material can be made into a variety of bushings, gaskets, guides, skateboards and spherical blocks and other components. Can be widely used in aircraft, automobiles, motorcycles, light machinery, textile machinery, petrochemicals, metallurgy, and home appliances.
