Sukan Olimpik Musim Sejuk ke-24 telah berakhir di Beijing beberapa hari lalu, dan Sukan Paralimpik musim sejuk juga akan bermula pada 4 Mac. Kisah indah Sukan Olimpik Musim Sejuk dan Sukan Paralimpik dipentaskan satu demi satu. Antaranya, elemen saintifik dan teknologi yang berkaitan dengan tekstil perindustrian sangat menonjol, dengan banyak sorotan. Banyak bahan baharu menyumbang kepada dua acara antarabangsa ini dan membantu China menjadi tuan rumah Sukan Olimpik dalam bidang hijau dan sains dan 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".
Tiang bercahaya gentian karbon pada majlis perasmian Sukan Olimpik Musim Sejuk:
Berat ringan, kekuatan tinggi dan kebolehkendalian yang baik
Menurut propsman majlis perasmian Sukan Olimpik Musim Sejuk, tiang bercahaya yang digunakan untuk upacara perasmian menggunakan bahan komposit gentian karbon, iaitu 9.5 meter panjang, 3.8 cm diameter di hujung kepala, 1.8 cm diameter di hujung. , dan berat 3 kg dan 7 Liang. Tiang yang kelihatan biasa ini bukan sahaja penuh dengan sains dan teknologi, tetapi juga penuh dengan estetika Cina yang menggabungkan kekerasan dan kelembutan. Tiang bercahaya asal ialah tiang penyangga keluli tahan karat, seberat 6 kg. Walaupun beratnya kecil, panjangnya terlalu panjang, mengakibatkan tiang bergegar teruk dan sukar dikawal. Berat ringan dan kekuatan tinggi bahan komposit bukan sahaja digunakan dalam kumpulan pancing, tetapi juga pada akhirnya.
Kasut kelajuan gentian karbon bercetak 3D domestik:
3 peratus - 4 peratus pengurangan berat badan
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.
Kereta salji domestik komposit gentian karbon tg800 domestik:
Turunkan pusat graviti untuk lebih kestabilan
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.
Topi keledar ski:
Prestasi perlindungan sekurang-kurangnya 20 peratus lebih tinggi daripada standard Eropah
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
Kabel pemanasan gentian karbon:
Penukaran langsung mengurangkan kehilangan haba
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.
Kelab Hoki Ais gentian karbon:
Tahan lasak dan tidak mudah patah
Kayu hoki ais gentian karbon yang digunakan oleh atlet adalah lebih tahan lama daripada kayu hoki ais biasa selepas penggunaan agen pembentuk bendalir. Menurut kakitangan RD, ejen pembentuk cecair salutan pada permukaan Kelab Hoki gentian karbon boleh meningkatkan keliatan kain gentian karbon di satu pihak dan meningkatkan kekuatan struktur keseluruhan kelab di sisi lain. Dengan menyediakan agen pembentuk cecair kecairan rendah, dan apabila tekanan inflasi acuan adalah malar, ia boleh memastikan bahawa masih terdapat agen pembentuk cecair yang mencukupi yang melekat pada permukaan substrat Club gentian karbon, dan mengambil bahagian dalam proses pembentukan seterusnya. Ejen pembentuk bendalir yang mencukupi dapat memastikan keliatan kelab hoki, supaya pemain tidak mudah retak atau memecahkan kelab apabila menghayun kayu hoki, Pastikan kayu hoki kuat dan tahan lama.
Malah, sebagai tambahan kepada pertumbuhan yang stabil dalam permintaan untuk komposit gentian karbon dalam industri tradisional seperti sukan dan masa lapang, aeroangkasa dan sebagainya, medan tenaga yang dikuasai oleh penghantaran kuasa dan kuasa angin dan medan pengangkutan yang dikuasai oleh pengangkutan kereta dan kereta api. juga telah menyuntik tenaga baharu ke dalam pembangunan industri gentian karbon. Ekonomi rendah-karbon dan hijau mempunyai kesan tarikan yang ketara pada penggunaan gentian karbon, dan juga menggalakkan industri tekstil perindustrian untuk memasuki peringkat baharu aplikasi perindustrian.
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.
