Pirms dažām dienām Pekinā noslēdzās 24. ziemas olimpiskās spēles, bet 4. martā sāksies arī ziemas paralimpiskās spēles. Ziemas olimpisko un paralimpisko spēļu brīnišķīgie stāsti tiek iestudēti cits pēc cita. Tostarp zinātniskie un tehnoloģiskie elementi, kas saistīti ar rūpnieciskajiem tekstilizstrādājumiem, ir ārkārtīgi pamanāmi, un tajos ir daudz svarīgāko. Daudzi jauni materiāli veicināja šos divus starptautiskos notikumus un palīdzēja Ķīnai uzņemt olimpiskās spēles zaļajā un zinātnes un tehnoloģiju jomā.
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".
Oglekļa šķiedras gaismas stabs ziemas olimpisko spēļu atklāšanas ceremonijā:
Viegls svars, augsta izturība un laba darbība
Saskaņā ar ziemas olimpisko spēļu atklāšanas ceremonijas rekvizītu, atklāšanas ceremonijā izmantotajā gaismas stabā ir izmantots oglekļa šķiedras kompozītmateriāls, kura garums ir 9,5 metri, diametrs galvas galā ir 3,8 cm, bet gala diametrs ir 1,8 cm. , un sver 3 kg un 7 Liang. Šis šķietami parastais stabs ir ne tikai pilns ar zinātni un tehnoloģijām, bet arī ar ķīniešu estētiku, kas apvieno cietību un maigumu. Oriģinālais gaismas stabs ir nerūsējošā tērauda balsta stabs, kas sver 6 kg. Lai gan svars ir mazs, garums ir pārāk garš, kā rezultātā stieņa kratīšana ir grūti kontrolējama. Kompozītmateriālu vieglais svars un augstā izturība tiek izmantota ne tikai makšķerkātu grupā, bet arī beigās.
Vietējās 3D drukātās oglekļa šķiedras ātrslidas:
Svara samazinājums par 3–4 procentiem
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.
Sadzīves tg800 oglekļa šķiedras kompozīta mājas sniega motocikls:
Nolaidiet smaguma centru, lai nodrošinātu lielāku stabilitāti
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.
Slēpošanas ķivere:
Aizsardzības veiktspēja ir vismaz par 20 procentiem augstāka nekā Eiropas standarts
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
Oglekļa šķiedras apkures kabelis:
Tiešā pārveidošana samazina siltuma zudumus
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.
Oglekļa šķiedras hokeja klubs:
Izturīgs un nav viegli saplīst
Sportistu izmantotās oglekļa šķiedras hokeja nūjas pēc šķidrumu veidojošā līdzekļa uzklāšanas ir izturīgākas par parastajām hokeja nūjām. Pēc RD personāla domām, pārklājuma šķidrumu veidojošais līdzeklis uz oglekļa šķiedras Hockey Club virsmas var palielināt oglekļa šķiedras auduma stingrību, no vienas puses, un uzlabot kluba kopējo strukturālo izturību, no otras puses. Nodrošinot zemas plūstamības šķidrumu veidojošo līdzekli un, ja veidnes piepūšanas spiediens ir nemainīgs, tas var nodrošināt, ka oglekļa šķiedras Club substrāta virsmai joprojām ir pievienots pietiekami daudz šķidrumu veidojošā līdzekļa, un piedalīties turpmākajā formēšanas procesā. Pietiekams šķidrumu veidojošais līdzeklis var nodrošināt hokeja kluba stingrību, lai spēlētājiem nebūtu viegli salauzt vai salauzt nūju, šūpojot hokeja nūju. Pārliecinieties, vai hokeja nūja ir izturīga un izturīga.
Faktiski papildus pastāvīgajam pieprasījuma pieaugumam pēc oglekļa šķiedras kompozītmateriāliem tradicionālajās nozarēs, piemēram, sporta un atpūtas, kosmosa un tā tālāk, enerģijas jomā dominē enerģijas pārvade un vēja enerģija un transporta jomā, kurā dominē automobiļu un dzelzceļa transports. ir arī devuši jaunu vitalitāti oglekļa šķiedras nozares attīstībā. Zema-oglekļa un videi nekaitīgai ekonomikai ir ievērojama ietekme uz oglekļa šķiedras izmantošanu, un tā arī veicina rūpnieciskās tekstilrūpniecības pāreju uz jaunu rūpnieciskā pielietojuma posmu.
