使用聚合材料能够在改进各种车辆设备的技术性能和使用寿命方面解决很多问题。在客车制造中早已成功地使用了贴面塑料来做客车内墙板和隔墙的装饰材料,从而改善了客室的外观和卫生状况。客车以及冷藏车车体的隔热使用了隔热性能很好的泡沫塑料。与以前使用的米波拉相比较,泡沫塑料的使用寿命较长,而且降低了修理成本,减轻了劳动强度。研制和广泛的采用合成闸瓦,在很大程度上保证了列车速度和轴重提高条件下的行车安全。同时也大大降低了铸铁的消耗量。现在采用的8-1-66和328-303号合成闸
The use of polymeric materials can solve many problems in improving the technical performance and service life of various vehicle equipment. Overlaying plastic has long been used successfully in the manufacture of passenger cars to provide interior trim and wall trim for passenger cars, thereby improving the appearance and hygiene of the guest rooms. The insulation of buses and refrigerated trucks body uses foam with good thermal insulation. Compared with the previous use of Micra, foam has a longer service life, lower repair costs and reduced labor intensity. Development and extensive use of synthetic brake shoe, to a large extent, to ensure the train speed and axle load conditions to improve traffic safety. At the same time also greatly reduce the consumption of cast iron. Now using the 8-1-66 and 328-303 gate
