Mõned päevad tagasi lõppesid Pekingis 24. taliolümpiamängud ja 4. märtsil algavad ka taliolümpiamängud. Järjest lavale tulevad taliolümpia ja paraolümpia imelised lood. Nende hulgas on tööstustekstiilidega seotud teaduslikud ja tehnoloogilised elemendid äärmiselt silmapaistvad, paljude esiletõstmistega. Paljud uued materjalid aitasid kaasa nendele kahele rahvusvahelisele sündmusele ja aitasid Hiinal korraldada rohelise ning teaduse ja tehnoloogia olümpiamänge.
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".
Süsinikkiust valguspost taliolümpiamängude avatseremoonial:
Kerge kaal, kõrge tugevus ja hea töökindlus
Taliolümpiamängude avatseremoonia rekvisiitori sõnul on avatseremooniaks kasutatav helendav varras omaks võtnud süsinikkiust komposiitmaterjali, mille pikkus on 9,5 meetrit, läbimõõt otsast 3,8 cm, otsa läbimõõt 1,8 cm. , ja kaalub 3 kg ja 7 Liangi. See pealtnäha tavaline poolus pole mitte ainult täis teadust ja tehnoloogiat, vaid täis ka Hiina esteetikat, mis ühendab kõvaduse ja pehmuse. Algne helendav post on roostevabast terasest tugipost, mis kaalub 6 kg. Kuigi kaal on väike, on pikkus liiga pikk, mille tagajärjeks on varras tugev värisemine ja raske kontrollida. Komposiitmaterjalide kerget kaalu ja suurt tugevust ei kasutata mitte ainult õngede rühmas, vaid ka lõpuks.
Kodused 3D prinditud süsinikkiust kiiruisud:
Kaalulangus 3–4 protsenti
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.
Kodumaine tg800 süsinikkiust komposiitmootorsaan:
Suurema stabiilsuse saavutamiseks langetage raskuskese
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.
Suusakiiver:
Kaitsejõudlus on Euroopa standardist vähemalt 20 protsenti kõrgem
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
Süsinikkiust küttekaabel:
Otsene muundamine vähendab soojuskadu
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.
Süsinikkiust jäähokiklubi:
Vastupidav ja mitte kergesti purunev
Sportlaste kasutatavad süsinikkiust jäähokikepid on pärast vedelikku moodustava aine pealekandmist vastupidavamad kui tavalised jäähokikepid. RD töötajate sõnul võib süsinikkiust Hockey Clubi pinnal olev kattevedelikku moodustav aine ühelt poolt suurendada süsinikkiust kanga tugevust ja teiselt poolt parandada klubi üldist konstruktsioonitugevust. Varustades madala voolavusega vedelikku moodustavat ainet ja kui vormi täitmisrõhk on konstantne, võib see tagada, et süsinikkiust Club substraadi pinnale on endiselt piisavalt vedelikku moodustavat ainet, ja osaleda järgnevas vormimisprotsessis. Piisav vedelikku moodustav aine võib tagada hokiklubi sitkuse, nii et mängijatel ei ole hokiklubi õõtsumisel kerge nuia lõhkuda või purustada. Veenduge, et hokikepp oleks tugev ja vastupidav.
Lisaks süsinikkiust komposiitide nõudluse pidevale kasvule traditsioonilistes tööstusharudes, nagu sport ja vaba aeg, lennundus ja nii edasi, domineerib energiavaldkond jõuülekanne ja tuuleenergia ning transpordivaldkond, kus domineerivad auto- ja raudteetransport. on süstinud uut elujõudu ka süsinikkiutööstuse arengusse. Vähese süsinikdioksiidiheitega ja keskkonnasäästlikul majandusel on märkimisväärne tõmbemõju süsinikkiu kasutamisele ning see soodustab ka tööstusliku tekstiilitööstuse jõudmist tööstusliku kasutamise uude etappi.
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.
