Beijing 2022 Winter Olympic and Paralympic Winter Games Torch
- "Flying"
It has such a close relationship with Jinshan!
Let's take a look.~

Putting a carbon fiber "coat" on the torch "flying"
Let's take a look at the CCTV news report first

During the New Year's Day holiday, the staff of the Shanghai Petrochemical Plant were busy assembling the Beijing Winter Olympic torch to "fly". According to the plan, 1,200 torches must be shipped to Beijing by mid-January.
In the production workshop, the black tows processed from petroleum products contain 12,000 carbon fiber filaments in each bundle. After three-dimensional weaving, the final woven torch shell can not see any seams and pores, and the whole shape is integrated.
"You look at this torch, this place looks like a streamer, the shell we developed, this is the ignition system, all wrapped in it. The feel is also good, this shell is very, very light. Huang Xiangyu, deputy general manager of Sinopec Shanghai Petrochemical Company, said.
"Feiyang" not only has a very dynamic and dynamic appearance, but its shell also contains "black technology". The "flying" shell must not only be resistant to fire and high temperatures, but also can be used in extremely cold weather. How to withstand this double test of "ice and fire", the mystery lies in a new type of material. It is carbon fiber.
"The quality of carbon fiber is only about 1/4 of steel, but the strength is 7 to 9 times that of steel." Lin Shengbing, general manager of Sinopec Shanghai Petrochemical Innovation Research Institute, introduced. In order to fit the concept of "green Olympic Games" and reflect the perfect integration of art design and technological innovation, the R&D team will focus on "carbon fiber". The use of carbon fiber and resin composite materials to make the Olympic torch is also the world's first.
The first evaluation of the Winter Olympic Organizing Committee to the torch "flying" is that it is light and very strong, and it cannot be broken no matter how it falls. Another is that the weather is very cold when the winter torch is passed, the traditional metal material does not feel very good, and the composite material can solve this problem and avoid the feeling of being very cold in the hand.
The shell was developed for three months
Multiple parties work together to overcome many problems one by one
In order to show the beauty of the winter Olympic torch, "Flying" changed the design of the past to use a metal partition "Olympic flame" and the torch shell, but used the torch shell as a container to directly place the "Olympic Flame" in it to burn.
Since the Beijing Winter Olympic Torch Relay will be carried out in a low temperature environment, "Feiyang" uses hydrogen as fuel, which is not only environmentally friendly, but also ensures that the torch can be used in extremely cold weather. However, when hydrogen is used as fuel, the combustion temperature will be higher than 800 ° C, which means that the flare shell must be able to withstand the high temperature of hydrogen combustion.
Therefore, the development of the "flying" torch shell took a full three months to overcome a number of technical problems one by one.
In 3 months, after countless adjustments, the researchers of "Shanghai Petrochemical" worked together with universities, research institutes and science and technology innovation enterprises to successfully solve the problems of foaming and cracking of the torch shell in the process of high-temperature preparation, and finally achieved a breakthrough in the application of carbon fiber composite materials under extreme conditions.
"The fire of the torch is burned from the inside, and ordinary composite materials cannot be burned in the fire. I learned that there is a science and technology innovation enterprise in Jinshan District, Shanghai, which has developed a resin, which is refractory, and we have taken it for test analysis. Finally, through the process adjustment, it meets the requirements of both temperature resistance and fire resistance, 800 °C, 900 °C can be. Huang Xiangyu introduced.
Huang Xiangyu's science and technology innovation enterprise is located in Shanghai's Jinshan Second Industrial Zone. Different from the metal materials commonly used in the past, the torch of this Winter Olympic Games is the application of the national patented technology product produced by the company - polysilica nitrogen resin, for shaping and coloring.
Although the carbon fiber itself is resistant to high temperatures, it is difficult for the resin used to withstand such a high temperature after being made into a composite material. "The polysilica nitrogen resin produced by our company can reach a maximum temperature of 1800 ° C, which is a good solution to this problem." Liu Zhangyou, general manager of the enterprise, said.
As a third-generation resin material, polysilica azelade resin has the characteristics of strong adhesion of machine and inorganic matter with high temperature resistance, and at the same time integrates the advantages of corrosion resistance, wear resistance, anti-fouling and waterproofing, and ultra-thin film. The natural and flexible shape of "Flying" benefits from the stereotyping treatment of polysilica nitrogen resin, while the strongly attached polysilica nitrogen resin coating achieves a seamless coloring effect, making this Chinese red shine for a long time.
The torch "flies" to carry the Olympic flame
At the same time, it also condenses the wisdom from Jinshan
Fly, Holy Flame!
Take off, Golden Mountain!
