众所周知,为了得到完好的粘结牢固的防蚀涂层,不仅要选择合适的涂料品种及其成份,而且在涂前要对表面进行适当的处理。这一重要原则对铁路车辆尤为适用。因为铁路车辆受到砂石的撞击,行驶时风速大以及灰尘多,这些因素都加剧了大气对防护层的损害。由于目前大多采用了自动高压喷洗设备对车辆(特别是客车)进行定期清洗,这对防护层也有影响。因此,采取有效的防蚀措施对降低维 As we all know, in order to get a good bond strong anti-corrosion coating, not only to select the appropriate coating varieties and their ingredients, but also in the coating before the surface to be properly handled. This important principle is particularly applicable to railway vehicles. Because railroad vehicles are hit by sand and gravel, wind speed is large and dusty, these factors exacerbate the atmosphere damage to the protective layer. Since most of the current use of automatic high-pressure jet washing equipment on vehicles (especially buses) for regular cleaning, which also affect the protective layer. Therefore, to take effective anti-corrosion measures to reduce the dimension
