"I was so excited that I didn't expect that the torch we were involved in making would be the main torch." After watching the opening ceremony of the Beijing Winter Olympics last night, Huang Weijian, general manager of Nantong Golden Auto Parts Technology Co., Ltd., was even more unexpected. Huang Weijian told reporters that out of secrecy, he did not know it before, but he felt extremely honored to see the moment when "Flying" was inserted into the torch platform. "We are very confident in our products, and it will undergo more than ten days of testing in the future."
On the evening of February 4, the opening ceremony of the 2022 Beijing Winter Olympics amazed the world, and the highly anticipated ceremony of lighting the flame was even more subversive and bold, directly inserting the relay torch "flying" into the torch platform. Zhang Yimou, the general director of the opening ceremony, explained, "This time, the last torch no longer needs to be lit, put on the torch stand, it is the torch." This small flame conveys the concept of low-carbon environmental protection. ”
Spinning and rising, like a ribbon fluttering torch "flying", how to achieve the Winter Olympic flame is unquenchable, and zero carbon emissions? Behind this is inseparable from the "credit" of a Nantong science and technology enterprise.
It is understood that the Winter Olympic torch is mainly divided into three parts: the outer streamer, the inner streamer and the hydrogen combustion device, which are jointly produced by a number of scientific research institutions and science and technology innovation enterprises. Among them, Nantong Gordon Auto Parts Technology Co., Ltd., located in Haimengang New Area, Nantong City, is mainly responsible for the assembly of outer streamers and the spraying of flame-retardant materials. The company is the "leader" in flame retardant and safety of domestic auto parts, recommended by the China Association of Automobile Industry and inspected and inspected by the Beijing Olympic Organizing Committee and the International Olympic Organizing Committee, and finally became the only enterprise to undertake the torch flame retardant project.
According to reports, "Feiyang" is the world's first use of "black technology" carbon fiber torch, its quality is only about 1/4 of steel, but the strength is 7 to 9 times that of steel. At the same time, in order to achieve zero emissions from combustion, the flare fuel uses hydrogen fuel, and combustion generally produces a high temperature of more than 800 degrees Celsius. After the upstream team solved the problems of carbon fiber high temperature resistance and combustion resistance, the flame retardant task that affected the overall integrity and fire resistance performance of the torch was left to Huang Weijian and his team.
"We are responsible for splicing, repairing, polishing, spraying the four links, each step can not be lost." Huang Weijian introduced that the first problem faced by the team was how to perfectly stitch together two irregularly shaped embryos. After splicing, the interface is obvious, and the embryo of the carbon fiber weave is relatively rough, and it is necessary to repair the surface defects with a high-temperature patch as a whole, and then carefully polish it to make the torch smooth and flat, and finally use a high-tech manipulator to spray the special flame retardant paint that can withstand thousands of degrees of high temperature baking on the torch, and finally make the torch present the most perfect state when the flame is passed.
In the past, the spraying process used on auto parts allowed deviations of about 10 microns. The standard thickness of the torch coating is 5 microns, and the allowable deviation is within plus or minus 1 micron, which is a huge challenge. In order to meet the demanding standards of torch design requirements, the company conducted a new research and development of the spraying process, dozens of combustion tests, and finally quenched out a special process only for the torch.
"I can't remember how many nights I tried and tried, but in the end we did it!" Speaking of which, the fatigue of 8 months of fighting seems to have never been felt. Correspondent Li Dandan Yangzi Evening News/Purple Cow News reporter Zhu Yayun
