De 24. olympiske vinterleker ble avsluttet i Beijing for noen dager siden, og de paralympiske vinterlekene starter også 4. mars. De fantastiske historiene om vinter-OL og paralympiske leker iscenesettes etter hverandre. Blant dem er de vitenskapelige og teknologiske elementene knyttet til industrielle tekstiler ekstremt fremtredende, med mange høydepunkter. Mange nye materialer bidro til disse to internasjonale begivenhetene og hjalp Kina med å arrangere de olympiske leker innen grønt og vitenskap og teknologi.
Stimulated by multiple factors such as the high attention of the state and the concentration of investment in high-tech fields, China's carbon fiber composite technology and industrial development have made gratifying achievements, which have made great achievements in the current Winter Olympic Games and winter Paralympic Games. These star products will appear in the 16th China International Industrial Textiles and nonwovens exhibition of cinte22.
The torch wears a carbon fiber "coat":
Combustion temperature ＞ 800 degree , normal use in hydrogen environment
Sinopec's Shanghai Petrochemical put on a carbon fiber "coat" for the torch of Beijing 2022 Winter Olympic Games and winter Paralympic Games. It is the first time in the world to make the Olympic torch shell with carbon fiber composite materials, which solves the technical problem of high temperature resistance of the torch when burning hydrogen fuel, making it "light, solid and beautiful", Realize normal use in hydrogen combustion environment higher than 800 degree . Shanghai Petrochemical and the eighth Nuclear Power Research Institute worked together to tackle key problems, introduced high-performance resin and made carbon fiber composites together with carbon fiber. Finally, through process adjustment, the combustion end of the upper half of the flare was vitrified at a high temperature above 1000 degree , which effectively solved the problems such as blistering and cracking of the flare shell in the process of high-temperature preparation, and met the requirements of both temperature resistance and fire resistance. Compared with the cold metal torch shell, "flying" makes the torchbearers feel warm and contributes to the "Green Olympics".
Karbonfiberlysende stang ved åpningsseremonien til de olympiske vinterleker:
Lett vekt, høy styrke og god betjening
I følge propsmannen for åpningsseremonien til de olympiske vinterleker, bruker den lysende stangen som ble brukt til åpningsseremonien karbonfiberkomposittmateriale, som er 9,5 meter langt, 3,8 cm i diameter ved hodeenden, 1,8 cm i diameter på enden , og veier 3 kg og 7 Liang. Denne tilsynelatende vanlige stangen er ikke bare full av vitenskap og teknologi, men også full av kinesisk estetikk for å kombinere hardhet og mykhet. Den originale lysende stangen er en støttestang i rustfritt stål, som veier 6 kg. Selv om vekten er liten, er lengden for lang, noe som resulterer i kraftig risting av stangen og vanskelig å kontrollere. Den lette vekten og høye styrken til komposittmaterialene brukes ikke bare i fiskestanggruppen, men også til slutt.
Innenlandske 3D-printede skøyter i karbonfiber:
3 prosent - 4 prosent vektreduksjon
Yang Jintian, a professor of sports biomechanics at Hebei University of economics and trade, and his research team have established a database of Speed Skaters' foot shape and plantar, and a plantar 3D scanning and printing system. It took more than one year to successfully develop the first generation of high-performance carbon fiber composite speed skates. Compared with China's high-end speed skating skates, the weight of carbon fiber skates is reduced by 3 percent - 4 percent , and the peel strength of skates is increased by 7 percent . Professor Yang Jintian said that the team will promote the iteration of skates. The second generation of domestic skates will be able to compete with similar foreign products, realize the "curve overtaking" of imported brands, and enhance the "technical strength" for the development of ice and snow sports in China.
Innenlands tg800 karbonfiberkompositt innenlands snøscooter:
Senk tyngdepunktet for mer stabilitet
In order to make the domestic snowmobile known as "F1 on ice" run at high speed, the materials used in the snowmobile body are light in weight and high in strength. Therefore, the manufacturing of snowmobile aims at carbon fiber composites and adopts high-strength domestic tg800 aerospace grade carbon fiber composites. The material is produced by TISCO Steel Co., Ltd. and can be used to make snowmobile and snowmobile helmet. After adopting carbon fiber composite materials, the snowmobile can reduce the body weight and center of gravity to the greatest extent on the premise of ensuring the safety of athletes, so as to make the snowmobile slide more smoothly. It is reported that the body weight of the carbon fiber composite double snowmobile is only about 50kg.
Skihjelm:
Beskyttelsesytelsen er minst 20 prosent høyere enn den europeiske standarden
The scientific research team of Dalian University of technology designed a ski helmet with new materials synthesized from carbon fiber, glass fiber and elastomer, which increased its stiffness by four times and its tensile strength by three times. Its shell is similar to the common curved wall panel in the rocket, which can play the effect of "pulling a thousand catties in four or two". The helmet weighs only about 700 grams, and its protective performance is at least 20 percent higher than the European standard without significantly increasing the weight and thickness. The helmet also fully takes into account the head shape characteristics of Asians. The team collected a large number of head shape data of national team athletes and developed design software, which realized the customization of athletes' helmets and effectively improved the comfort of wearing for a long time
Karbonfiber varmekabel:
Direkte konvertering reduserer varmetapet
Carbon fiber heating cables are laid under the floor of the apartment rooms where the athletes of the Winter Olympic Games and the winter Paralympic Games live. Electric heating is used in winter to directly convert electric energy into heat energy and reduce heat loss. All the electric energy used comes from wind power generation in Zhangjiakou, which is clean, renewable and green. The staff of the operation Department of the Olympic Village said that Zhangjiakou Winter Olympic village was built in accordance with China's highest three-star standard of green construction. By taking a series of land-saving, energy-saving, material-saving and water-saving measures, the Winter Olympic village can not only meet the concept of Green Olympics, but also fully meet the needs of the Winter Olympic Games.
Karbonfiber ishockeyklubb:
Slitesterk og ikke lett å bryte
Ishockeykøllene i karbonfiber som brukes av idrettsutøvere er mer holdbare enn vanlige ishockeykøller etter påføring av væskedannende middel. I følge RD-personellet kan beleggvæskedannende middel på overflaten av karbonfiber Hockey Club øke seigheten til karbonfiberduken på den ene siden og forbedre den generelle strukturelle styrken til klubben på den andre siden. Ved å tilveiebringe et væskedannende middel med lav fluiditet, og når oppblåsningstrykket i formen er konstant, kan det sikre at det fortsatt er nok væskedannende middel festet til overflaten av karbonfiberklubbsubstratet, og delta i den påfølgende formingsprosessen. Tilstrekkelig væskedannende middel kan sikre hockeyklubbens seighet, slik at det ikke er lett for spillerne å knekke eller knekke klubben når de svinger hockeykøllen. Sørg for at hockeykøllen er sterk og holdbar.
Faktisk, i tillegg til den jevne veksten i etterspørselen etter karbonfiberkompositter i tradisjonelle industrier som sport og fritid, romfart og så videre, er energifeltet dominert av kraftoverføring og vindkraft og transportfeltet dominert av bil- og jernbanetransport har også injisert ny vitalitet i utviklingen av karbonfiberindustrien. Den lave-karbonøkonomien og den grønne økonomien har en betydelig tiltrekkende effekt på bruken av karbonfiber, og fremmer også den industrielle tekstilindustrien til å gå inn i et nytt stadium av industriell anvendelse.
At the beginning of the Spring Festival, what opportunities will industrial textiles and nonwovens usher in? From September 6 to 8, 2022, cinte22's 16th China International Industrial Textiles and nonwovens exhibition will show the latest products and technologies in this field.
Gather global industry leaders, let's look forward to it.
