Aerogel Material Apply in High-Speed Railway/ Metro

About HSR railways Development Worldwide, You Have to Know

The table below compares countries/economies according to their level of deployment of HSR railways, in order from most development to least, based on data from the International Union of Railways (UIC) and from other sources that provide updated data. A number of other countries are listed as having long-term planning for HSR, but no funding has been allocated to their programs to date. In addition, other sources indicate that some countries have HSR systems in place, even though UIC has indicated that they do not.

Long-term Prospects for High-Speed Rail

HSR advocates further argue that the throughput (in terms of numbers of people moved from place to place for a given investment) provided by high-speed rail far outpaces those provided by highways or airports. In the chart to the left, the US High Speed Rail Association depicts how high-speed rail offers significant time savings compared with flying or driving between downtown San Francisco and downtown Los Angeles in California.

Transportation benefits. Many would argue that economic development should not be the main measure of a transportation system, but that its ability to move people and goods should be the primary consideration. That is how highway and airport projects are evaluated. Every country that builds HSR does so for the high capacity, sustainable mobility it delivers, first and foremost, with economic development and better safety as beneficial side effects.

Energy savings. Reducing the number of cars on roads and highways translates into big energy savings and a reduced demand for oil. According to International Union of Railways (UIC) data, high-speed rail is more than four times as energy efficient as driving in cars and nearly nine times more efficient than flying.
 

Environmental considerations. High-speed rail clearly offers a path to lower greenhouse gas emissions than other modes of transportation. If HSR services can entice people out of their cars by offering convenience and speed at a low cost, this would significantly reduce societal energy consumption and carbon emissions. The California High-Speed Rail Authority (CHSRA), for example, estimates that by 2040, California’s HSR system will reduce vehicle miles of travel in the state by 10 million miles each day; over a 58-year period, the system will reduce auto traffic on the state’s highways by over 400 billion miles of travel. In addition, CHSRA estimates that starting in 2030, the state will see a reduction of 93 to 171 flights daily, which translates into improved air quality and improved health, along with the economic benefits of a more energy-efficient transportation system.

Traditional insulation materials in High-Speed Railway/ Metro have such weakness,

• High thermal conductivity and the thickness of the insulation layer taking up a lot of space.
• High density, which is not conducive to reducing the weight of the body.
• Poor environmental performance, may release toxic gas when burning.

Compared to mentioned above, Sino-Aerogel Insulation Materials have such advantages, 

• Low thermal conductivity, good insulation effect, the same insulation effect only requires 1/5 to 1/3 of the thickness of traditional insulation materials, saving space.
• Excellent fireproof performance, providing valuable time for safe evacuation of personnel in case of accidental fire.
• Sound insulation and noise reduction, making the carriage more quiet and comfortable.
• Non-toxic and harmless, no pollution to the environment.
• Low density, good tensile and compressive properties, reducing the body mass while ensuring a certain level of strength.
