In recent years, the construction of high-speed railways has developed rapidly. At the same time, higher requirements have been put forward for the smoothness of train operation and the safety of bridge structures such as anti-interference, torsional rigidity, heavy load, and wear resistance. The wear-resistant material of UHMWPE board bridge support is an indispensable component in the construction of high-speed rail, and its performance requirements have been continuously improved.
The bridge support not only transmits the load on the upper part of the bridge, but also adjusts the relative displacement between the upper structure and the lower structure, which plays a very important role in the safety and comfort of high-speed trains. It is stipulated in the bridge construction that high-speed railway bridges with a speed exceeding 200km/h must be equipped with bridge bearings.


The wear-resistant material of the bridge support is the most important sliding part in the support, and the wear-resistant material of the UHMWPE board bridge support mainly plays the role of bearing and friction. The quality of the plate directly affects the bridge support Performance and service life. The use of ultra-high molecular weight polyethylene board will inevitably ensure the excellent load-bearing capacity, creep resistance, self-lubrication and wear resistance required by the wear-resistant material of the bridge support.
Ultra-high molecular weight polyethylene sheets can meet the above various needs and are widely used in bridge supports of high-speed railways and maglev trains to meet the needs of rapid displacement of the supports.
