High-speed rail has developed rapidly in the past few years and plays an increasingly important role in the national economy and daily life. In order to meet the goals of energy saving, safety, environmental protection and comfort, the strength, fatigue performance, light weight, and manufacturability of the materials used on the high-speed rail must be of a higher level. The applications of Weher Thermal Energy on the high-speed rail are all lightweight and high-strength thermal insulation insulation. hot material.

In the cold winter, building roof and wall insulation have become the focus of attention. At present, nearly 2 billion square meters of new buildings are newly built every year in my country, which is more than the total construction volume of all developed countries, but more than 95% of buildings
