The export of China's high-speed rail is of great significance, because this is not only the "going out" of a single industry, but the "going out" of the entire industrial chain ". Although the current market scale of China's high-speed rail is small, once it is recognized by overseas markets, it will reshape the global brand image of made in China and drive the development of upstream and downstream segments of the industrial chain.
For high-speed railways, the strength, fatigue performance, lightweight, and manufacturability of the materials used should have a higher level. Therefore, more and more new materials are used in this, and now they are generally in the following aspects:
composite car body
Composite materials have begun to be used in vehicles, and the amount of them is increasing, which represents the future development trend. Fiber reinforced resin matrix composites (FRP) because of high specific strength (stiffness), fatigue resistance, corrosion resistance, heat insulation, flame retardant, strong designability and other advantages, Britain, Japan and Germany have been applied to non-structural parts in the 1960 s, and are now increasingly used in various structural parts, such as glass fiber reinforced plastic, aramid fiber reinforced epoxy resin, etc. at the front end of car bodies and car heads. At present, in Western Europe, glass fiber accounts for 58%, aramid fiber accounts for 20%, carbon fiber accounts for 20%, and other 2% of composite materials used for railway vehicles. According to the type of resin, polyester accounts for 35%, vinyl ester accounts for 22%, epoxy resin accounts for 21%, phenolic resin accounts for 15%, and modified acrylic resin accounts for 4%, others accounted for 3%.
GRB-801 train car body cleaning agent
It is mainly used for the cleaning of the outer surface of the vehicle and the cleaning of the interior trim panel of the vehicle, subway (including light rail) train and maglev train. This product is a compound type low foam products, suitable for scrub, scrub, high pressure spray cleaning process.
Bogie
The frame of the bogie is a particularly important high-strength component, which is related to the safety of the entire vehicle. The turret must meet the requirements of safety, operating comfort, wear resistance and easy maintenance.
The use of high-quality carbon steel, low-alloy low-carbon high-strength steel, weathering steel manufacturing framework. Recent research hotspots are polymer composites and aluminum alloy-made frameworks.
  Efficient cleaning agent for GRB-802 train air conditioning
It is used for cleaning heavy oil pollution such as air-conditioning shell, air-conditioning wing, bogie, air pump radiator, motor shell, wheel hub, etc. of EMU, subway (including light rail) train and maglev train.
Vehicle interior and equipment
The interior and equipment of the vehicle mainly include decorative panels, toilets, washing rooms, seats and water tanks, etc., which are mainly made of aluminum alloy and polymer materials. For example, the decorative panels are made of aluminum alloy and laminated with a layer of non-combustible fiber reinforced plastic. Toilets, washing rooms, seats and water tanks should also take into account hygiene and corrosion resistance, and non-combustible ones are preferred.
