De 24. olympiske vinterlege sluttede i Beijing for et par dage siden, og de paralympiske vinterlege begynder også den 4. marts. De vidunderlige historier om de olympiske vinterlege og de paralympiske lege iscenesættes efter hinanden. Blandt dem er de videnskabelige og teknologiske elementer relateret til industrielle tekstiler ekstremt fremtrædende, med mange højdepunkter. Mange nye materialer bidrog til disse to internationale begivenheder og hjalp Kina med at være vært for de olympiske lege i grønt og videnskab 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".
Kulfiber lysende stang ved åbningsceremonien for de olympiske vinterlege:
Let vægt, høj styrke og god betjeningsevne
Ifølge propsman for åbningsceremonien for de olympiske vinterlege anvender den lysende stang, der blev brugt til åbningsceremonien, kulfiberkompositmateriale, som er 9,5 meter langt, 3,8 cm i diameter ved hovedenden, 1,8 cm i diameter for enden , og vejer 3 kg og 7 Liang. Denne tilsyneladende almindelige stang er ikke kun fuld af videnskab og teknologi, men også fuld af kinesisk æstetik med at kombinere hårdhed og blødhed. Den originale lysende stang er en støttestang i rustfrit stål, der vejer 6 kg. Selvom vægten er lille, er længden for lang, hvilket resulterer i kraftige rystelser af stangen og svær at kontrollere. Kompositmaterialernes lette vægt og høje styrke bruges ikke kun i fiskestangsgruppen, men også i sidste ende.
Indenlandske 3D-printede kulfiberskøjter:
3 procent - 4 procent vægtreduktion
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.
Indenlandsk tg800 kulfiber komposit indenlandsk snescooter:
Sænk tyngdepunktet for mere 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:
Beskyttelsesydelsen er mindst 20 procent højere end den europæiske standard
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
Kulfiber varmekabel:
Direkte konvertering reducerer varmetabet
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.
Kulfiber ishockeyklub:
Holdbar og ikke let at bryde
Ishockeystavene af kulfiber, der bruges af atleter, er mere holdbare end almindelige ishockeystave efter påføring af væskedannende middel. Ifølge RD-personalet kan belægningsvæskedannende middel på overfladen af kulfiber Hockey Club øge sejheden af kulfiberstof på den ene side og forbedre klubbens overordnede strukturelle styrke på den anden side. Ved at tilvejebringe et væskedannende middel med lav fluiditet, og når støbeformens oppustningstryk er konstant, kan det sikre, at der stadig er nok væskedannende middel fastgjort til overfladen af kulfiber Club-substratet og deltage i den efterfølgende formningsproces. Tilstrækkeligt væskedannende middel kan sikre hockeykøllens sejhed, så spillerne ikke er nemme at knække eller knække køllen, når de svinger hockeykøllen. Sørg for, at hockeystaven er stærk og holdbar.
Faktisk, ud over den konstante vækst i efterspørgslen efter kulfiberkompositter i traditionelle industrier som sport og fritid, rumfart og så videre, er energifeltet domineret af kraftoverførsel og vindkraft og transportområdet domineret af bil- og jernbanetransport har også injiceret ny vitalitet i udviklingen af kulfiberindustrien. Den lave-kulstoføkonomi og den grønne økonomi har en betydelig tiltrækningseffekt på anvendelsen af kulfiber og fremmer også den industrielle tekstilindustri til at gå ind i en ny fase af industriel 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.
