Safely and effectively inactivate viruses
Enterprise: Guangdong Excimer Optoelectronics Technology Co., Ltd
Product: 222nm excimer disinfection tower
"It only takes 5 seconds to kill the virus on the surface of the body." Recently, the reporter came to the production base of Guangdong Excimer Optoelectronics Technology Co., Ltd. (hereinafter referred to as "Excimer Optoelectronics Company") in Taoyuan Town, Heshan City, to explore the "black technology" on the Winter Olympic Games - 222nm excimer disinfection tower.
"At the beginning of January this year, the 222nm excimer disinfection tower designed and produced by our company officially passed the acceptance of the State General Administration of Sports. The State General Administration of Sport also issued us a letter of authorization for the 'Supplier of Epidemic Prevention and Killing Equipment for the National Olympic Sports Center'. Shang Yuchao, general manager of the excimer optoelectronic company, introduced that the disinfection tower produced by the company will be installed at the entrance and exit of the 9 major venues of the Beijing Winter Olympics, at which time, all Olympic athletes and coaches will pass under the disinfection tower to complete the disinfection and "escort" the Beijing Winter Olympics.
The reporter saw on the spot that the 222nm excimer disinfection tower integrates face recognition, temperature measurement, killing and other functions into one, and can guide users through the whole process of fuselage voice broadcast and video demonstration, which is very efficient.
"The 222nm excimer lamp is our company's 'star product', and the 222nm excimer lamp is designed in the middle and lower three parts of the disinfection tower, which can achieve no dead end killing." Shang Yuchao said that the 222nm excimer lamp has truly realized the "coexistence of man and machine", and now it has achieved mass production, and the product has been recognized by the market.
Ultraviolet (222 nm) can destroy DNA or RNA in microbial muscle cells, which can safely and effectively inactivate the virus. At the same time, the radiation of the product cannot easily pass through the tear layer and the stratum corneum of the skin, so it will not cause damage to the eyes and skin like the traditional ultraviolet light (254 nm), and can be used in an environment where people are present. "In the past, the 222nm ultraviolet light source was monopolized by Japan and the United States, and now we have completely got rid of the situation that the excimer lamp was 'stuck in the neck' by foreign companies." Shang Yuchao said.
As a high-tech enterprise specializing in the research and development and production of excimer special light sources and supporting facilities, excimer optoelectronics products are widely used in various fields. The company relies on 222nm ultraviolet technology to develop a series of products, highly adapted to the needs of epidemic prevention and control in different scenarios, and has completed the development and mass production of a number of products.
Jiangmen's "light technology" helped the Winter Olympics build a solid epidemic prevention barrier
Enterprise: Guangming Yuanguang Technology Co., Ltd
Product: All-round UV disinfection conveyor
On a full-range ultraviolet disinfection transmitter with a length of nearly 3 meters, it takes only 5 seconds for the tight package to enter the disinfection chamber from the entrance of the equipment to the completion of disinfection. Nowadays, this "light technology" epidemic prevention weapon has entered the National Olympic Sports Center to help the Winter Olympic Games build a solid epidemic prevention barrier.
Guangming Yuanguang Technology Co., Ltd. (hereinafter referred to as "Guangming Yuanguang Technology Co., Ltd.") is the R & D and production enterprise of this equipment. Feng Jinxiang, vice president of the company, introduced that the all-round ultraviolet disinfection transmitter donated by the company to the Organizing Committee of the Beijing Winter Olympic Games will be placed in the National Olympic Sports Center to support the staff to carry out epidemic prevention and control work.
In the exhibition hall corridor of Guangming Yuanguang Technology Co., Ltd., an exhibition covering seven colors of visible light such as "red, orange, yellow, green, blue, and purple" and ultraviolet, infrared, X-ray and other light sources is particularly eye-catching. Feng Jinxiang said that the secret behind the "light technology" epidemic prevention weapon that went to Beijing to help the epidemic prevention work of the Winter Olympic Games is among them.
"High-energy ultraviolet light in the 200-280 nm band can destroy the molecular structure of DNA or RNA in bacterial viruses, achieve 99.9% sterilization effect, and quickly and efficiently eliminate bacteria and viruses on the surface of items." Feng Jinxiang said that the principle of the all-round ultraviolet disinfection transmitter donated by enterprises comes from this.
"The company has always paid great attention to technology research and development, we have our own professional scientific research team, and in 2015 set up a 'postdoctoral research workstation', is a national high-tech enterprise." Feng Jinxiang introduced that the current company also has 222nm far-ultraviolet sterilization door, 222nm far-ultraviolet disinfection module, medical disinfection machine and other special light source technology related products.
"It is our company's honor to help the Winter Olympics go smoothly." Talking about being a member of the "Jiangmen Elements" of the Winter Olympics, Feng Jinxiang said that this is a continuation of the company's concept of "empowering a better life with 'light technology'".

Enterprise: Jiangmen Pengcheng Helmet Co., Ltd
Product: LS2 helmet
At the 2022 Beijing Winter Olympics, the LS2 helmet developed and produced by Jiangmen Pengcheng Helmet Co., Ltd. (hereinafter referred to as "Pengcheng Helmet Company") was selected by the two national teams of Austria and Switzerland as special equipment for participating in snowmobiling sports. The high-quality "Made in Jiangmen" will be unveiled at the Beijing Winter Olympics, which is exciting.
Pengcheng Helmet Company was founded in 1990, located in Gonghe Town, Heshan City, is a private enterprise focusing on the production of high-end motorcycle helmets and motorcycle clothing. In recent years, the helmets produced by Pengcheng Helmet Company have successively participated in the world's top events and are deeply loved by motorcycle sports enthusiasts at home and abroad.
Snowmobiling is one of the three major skiing sports at the 2022 Beijing Winter Olympics. The race track is the first in the world to include a 360-degree turn. The track has a total length of 1615 meters, a maximum gradient of 18% and 16 turns. The maximum speed of the snowmobile can exceed 130 km / h, and the protection of the head is crucial because of the need for non-stop turns, sharp stops, and the possibility of rollover accidents during the race.

"Ignite" the spirit of craftsmanship in fine kung fu
Enterprise: Jiangmen Xinhui District Yuanda Tools Co., Ltd
Product: "Flying" flare burning tube
"At the beginning of October 2021, we received an order for 10,000 'flying' torch burning tubes for the Winter Olympics, requiring them to be completed within 2 months. The shape and accuracy of the combustion tube will directly affect the shape of the Torch Flame of the Winter Olympics, and there can be no mistakes. Recently, Ma Jiaqiao, general manager of Jiangmen Xinhui District Yuanda Tools Co., Ltd. (hereinafter referred to as "Yuanda Tools Company"), showed the finished combustion pipe to reporters.
After graduating from Magaqiao University, he worked in Guangdong Xinhui Agricultural Machinery Factory Co., Ltd. for 10 years, and then founded Yuanda Tool Company, which is deeply engaged in the research and development and manufacturing of tool machine tools.
"Making combustion tubes can be said to us to be 'laymen doing things inside', but we are confident of completing the order task." Magaqiao said.
"Material selection is a key step. The Winter Olympic torch needs to be resistant to high temperatures, so we chose a 304 stainless steel seamless tube, a combustion tube made of this material that can withstand high temperatures of 1300 degrees. Magaqiao said that the bottom of the combustion tube is connected to the pressure reducing valve of the hydrogen tank, and in order to ensure air tightness, the diameter of the nozzle must be controlled in the range of 5.985mm to 6.015mm.
The reporter learned that the production process of the combustion tube is exquisite everywhere, and each link needs to spend a lot of energy. "The combustion tube is not a regular item, there are complex spatial curves, the diameter also changes, as long as there is a little deviation in the production process, it may cause the combustion pipe to fail to fit into the torch." Magaqiao said that in order for the combustion tube to smoothly "fit" the torch, they made six sets of forming stamping dies to ensure dimensional and shape accuracy.
"The hardest thing was to make these 24 pores of different sizes on the combustion tube." Ma Jiaqiao introduced that the 24 air holes have their own three-dimensional coordinates, angle requirements and diameter requirements, and a little error will directly affect the shape of the flame, which is a great test of the worker's technology.
"Ignite" the spirit of craftsmanship, fine in the kung fu. In mid-December 2021, the combustion tubes produced by Yuanda Tools passed the acceptance of the Ministry of Science and Technology and the China Aerospace Group, and won high reputation for low price, high quality and high efficiency.
With ingenuity, do a good job of "flying" torch inner streamers
Enterprise: Jiangmen Dinghao Copper Art Products Co., Ltd
Product: "Flying" flare inner streamer
The Beijing Winter Olympics are about to kick off, and the "flying" torch of the Winter Olympics is about to be lit. The inner streamer of the "Flying" torch is produced from Jiangmen Dinghao Copper Art Products Co., Ltd. (hereinafter referred to as "Dinghao Copper Art Products Company").
"It represents Made in China, and every detail has to be the best." Recently, the reporter came to the top copper art products company, the company's founders Li Xiaojun and He Zhongkai are carefully inspecting the processed inner streamer. The curved and coiled inner streamer is lightweight in the hand, but its production process is very "thick".
The combustion port of the "flying" torch is between the inner shell, as the inner streamer of the inner shell of the torch, not only to pay attention to the beauty of its "ready to come out", but also through special technology and almost perfect polishing, so that it can withstand the high temperature of the flame.
"During the production process, we used the lost wax method and the sand casting method, two methods originated in the Spring and Autumn Period, and were first applied to the precision casting of bronze utensils." According to the relevant enterprise Ping Aluminum Group, the production of each completed streamer product needs to go through more than 30 processes before and after, in addition to more than 20 strict testing procedures.
The shape of the inner streamer bends the inner wind, not only to consider how to fit the shell perfectly, but also to solve many technical problems that have not been solved in the industry, such as porosity prevention, shrinkage deformation, prismatic polishing, etc., which have very high requirements for process and quality.
Li Xiaojun and He Zhongkai are both craftsmen. "We have been doing this process for more than 20 years, and we are sure and confident." Li Xiaojun said that this is the most meaningful challenge in the company's more than 3 years since its establishment.
After getting the drawings, Li Xiaojun and He Zhongkai buried them in research and attempts again and again with the ingenuity of excellence. "During that time, I often worked overtime, and I thought that I must do this thing." Li Xiaojun said that during the research process, the local government department in Jiangmen also brought experts to assist them. In November last year, Li Xiaojun and He Zhongkai successfully broke through a number of process problems in the industry and successfully overcome the technical difficulties of casting, producing and polishing the internal streamer. Today, the inner streamer produced by Dinghao Copper Products Company has also been successfully delivered.
