On February 4, 2022, the world-renowned Beijing Winter Olympic Games opened grandly at the National Stadium "bird's nest". After about 1200 torchbearers passed, the Beijing Winter Olympic torch "flew" and lit the "main torch" of the National Stadium. So far, China Petroleum & Chemical Corporation(600028) successfully completed the task of ensuring the production of the Winter Olympic torch.
The shell of Beijing Winter Olympic torch is made of carbon fiber composite material developed by China Petroleum & Chemical Corporation(600028) Sinopec Shanghai Petrochemical Company Limited(600688) , which solves the technical problem of high temperature resistance of torch during hydrogen fuel combustion. This is the first time in the world that the Olympic torch shell is made of carbon fiber composite materials to help the "Green Olympics". China Petroleum & Chemical Corporation(600028) Sinopec Shanghai Petrochemical Company Limited(600688) faced the difficulties, took the mass production of the torch as a glorious mission, and successfully completed the production task of the Winter Olympic torch by giving full play to the advantages of the upstream and downstream industrial chain and strengthening the coordination with the torch design team and the combustion system development unit.
In addition, the first use of hydrogen energy as torch fuel in the Beijing Winter Olympics has also become a highlight. Liquefied natural gas or propane and other gases were widely used as torch fuel in previous Olympic Games. At the opening ceremony of this winter Olympic Games, hydrogen provided by China Petroleum & Chemical Corporation(600028) Yanshan Petrochemical ignited the "main torch" of the Winter Olympic Games, fully reflecting the green and low-carbon concept of Beijing Winter Olympic Games. In order to ensure the hydrogen supply of the main torch of the Winter Olympic Games, China Petroleum & Chemical Corporation(600028) Yanshan Petrochemical has established a support team to formulate detailed work plans and guarantee measures from various links such as hydrogen filling, testing and transportation support, so as to ensure the high quality and safety of the supplied hydrogen.
China Petroleum & Chemical Corporation(600028) put a carbon fiber "coat" on the "flying" of the torch. The torch is one of the most concerned elements in the Olympic Games. Under the organization and coordination of Beijing Winter Olympic Organizing Committee, China Petroleum & Chemical Corporation(600028) shoulders the responsibility of the chain leader of the industrial chain, and takes the lead in the research and development of carbon fiber composites for the shell of the torch and the mass production of the torch. With the full support of the cooperation team, we have jointly opened up the whole process integrating the torch shell, inner streamer, combustion system, kindling lamp and terminal detection and delivery products, and completed the mass production task of the Winter Olympic torch on time, quality and quantity. China Petroleum & Chemical Corporation(600028) Sinopec Shanghai Petrochemical Company Limited(600688) has the honor to manufacture the beautiful "Feiyang" torch barrel. Using self-developed products and technologies, it is made of "black technology" new material carbon fiber composite, so that "Feiyang" integrates the characteristics of "light, solid and beautiful". It is light and high-temperature resistant, and can be used normally in the hydrogen combustion environment higher than 800 ℃.
It is understood that on January 18, 1200 "flying" torches developed and mass produced under the leadership of China Petroleum & Chemical Corporation(600028) Sinopec Shanghai Petrochemical Company Limited(600688) arrived in Beijing safely under the escort of full-time escorts; On January 27, the 1200 carbon fiber torches "flew" and officially delivered to the Beijing Winter Olympic Organizing Committee on the occasion of the 8-day countdown to the opening of the Beijing 2022 Winter Olympic Games. The relay began on February 2, opening the prelude to the Beijing Winter Olympic Games.
Carbon fiber is a new material with excellent mechanical properties. Its quality is one quarter of that of steel, but its strength is seven to nine times that of steel. It is known as "black gold" in materials. China Petroleum & Chemical Corporation(600028) owns the carbon fiber technology developed with independent intellectual property rights, ranks first in China and third in the world, and is the first large tow carbon fiber manufacturer in China and the fourth in the world.
The torch of the Winter Olympic Games adopts three-dimensional weaving technology, which is a technological breakthrough in carbon fiber molding. In the production workshop, there are black tow, each containing 12000 carbon fiber filaments. After three-dimensional three-dimensional weaving, it is finally woven into the torch shell like "knitting sweater", without any seams and pores, and the whole shape is integrated. In addition, it can solve the problem of high combustion temperature of carbon fiber and 688} in the preparation process of carbon fiber, which can not only meet the requirements of high combustion temperature, but also achieve the cracking resistance of carbon fiber in the preparation process of flame.
