U Pekingu su prije nekoliko dana završene 24. Zimske olimpijske igre, a 4. marta počeće i zimske paraolimpijske igre. Čudesne priče o Zimskim olimpijskim i paraolimpijskim igrama nizaju se jedna za drugom. Među njima, naučni i tehnološki elementi koji se odnose na industrijski tekstil su izuzetno istaknuti, sa mnogo naglasaka. Mnogi novi materijali doprinijeli su ova dva međunarodna događaja i pomogli Kini da bude domaćin Olimpijskih igara u zelenom i nauci i tehnologiji.
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".
Svjetleći stup od karbonskih vlakana na ceremoniji otvaranja Zimskih olimpijskih igara:
Mala težina, visoka čvrstoća i dobra operativnost
Prema rekviziteru ceremonije otvaranja Zimskih olimpijskih igara, svjetleći stup koji se koristi za ceremoniju otvaranja koristi kompozitni materijal od karbonskih vlakana, koji je dug 9,5 metara, 3,8 cm u prečniku na vrhu, 1,8 cm u prečniku na kraju , i težak je 3 kg i 7 Lianga. Ovaj naizgled običan stup ne samo da je pun nauke i tehnologije, već je pun i kineske estetike kombinovanja tvrdoće i mekoće. Originalni svjetleći stup je potporni stup od nehrđajućeg čelika, težine 6 kg. Iako je težina mala, dužina je preduga, što rezultira jakim podrhtavanjem motke i teškom kontrolom. Mala težina i visoka čvrstoća kompozitnih materijala ne koriste se samo u grupi štapova za pecanje, već i na kraju.
Domaće klizaljke od 3D štampanih karbonskih vlakana:
3 posto - 4 posto smanjenje težine
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.
Domaće motorne sanke od kompozita od karbonskih vlakana tg800:
Spustite centar gravitacije za veću stabilnost
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.
Skijaška kaciga:
Performanse zaštite su najmanje 20 posto veće od europskog standarda
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
Kabl za grijanje od karbonskih vlakana:
Direktna konverzija smanjuje gubitak topline
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.
Hokejaški klub od karbonskih vlakana:
Izdržljiv i nije ga lako slomiti
Štapovi za hokej na ledu od ugljeničnih vlakana koje koriste sportisti su izdržljiviji od običnih štapova za hokej na ledu nakon nanošenja sredstva za formiranje tečnosti. Prema osoblju RD-a, sredstvo za formiranje tečnosti za oblaganje na površini hokejaškog kluba od karbonskih vlakana može povećati žilavost tkanine od karbonskih vlakana s jedne strane i poboljšati ukupnu strukturnu čvrstoću palice s druge strane. Pružajući nisko fluidno sredstvo za formiranje fluida, i kada je pritisak naduvavanja kalupa konstantan, može osigurati da još uvijek ima dovoljno tečnog sredstva za formiranje pričvršćeno na površinu Club podloge od karbonskih vlakana i da učestvuje u kasnijem procesu oblikovanja. Dovoljno tečnog sredstva za formiranje može osigurati čvrstinu hokejaške palice, tako da igračima nije lako puknuti ili slomiti palicu pri zamahu hokejaškom štapom. Uvjerite se da je hokejaški štap jak i izdržljiv.
Zapravo, pored stalnog rasta potražnje za kompozitima od ugljičnih vlakana u tradicionalnim industrijama kao što su sport i slobodno vrijeme, zrakoplovstvo i tako dalje, energetskim poljem kojim dominiraju prijenos energije i energija vjetra i transportnim poljem dominiraju automobilski i željeznički transport su također ubrizgali novu vitalnost u razvoj industrije karbonskih vlakana. Nisko{0}}ugljična i zelena ekonomija ima značajan efekat na primjenu karbonskih vlakana, a također potiče industrijsku tekstilnu industriju da uđe u novu fazu industrijske primjene.
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.
