Fa uns dies van acabar a Pequín els 24è Jocs Olímpics d'hivern, i el 4 de març també començaran els Jocs Paralímpics d'hivern. Les meravelloses històries dels Jocs Olímpics d'hivern i dels Paraolímpics s'escenifiquen una darrere l'altra. Entre ells destaquen els elements científics i tecnològics relacionats amb el tèxtil industrial, amb molts aspectes destacats. Molts nous materials van contribuir a aquests dos esdeveniments internacionals i van ajudar a la Xina a acollir els Jocs Olímpics en verd i ciència i tecnologia.
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".
Pal lluminós de fibra de carboni a la cerimònia d'obertura dels Jocs Olímpics d'hivern:
Pes lleuger, alta resistència i bona operabilitat
Segons el punter de la cerimònia d'obertura dels Jocs Olímpics d'hivern, el pal lluminós utilitzat per a la cerimònia d'obertura adopta un material compost de fibra de carboni, que té 9,5 metres de llarg, 3,8 cm de diàmetre a l'extrem del cap, 1,8 cm de diàmetre al final. , i pesa 3 kg i 7 Liang. Aquest pal aparentment normal no només està ple de ciència i tecnologia, sinó que també està ple d'estètica xinesa que combina duresa i suavitat. El pal lluminós original és un pal d'acer inoxidable, amb un pes de 6 kg. Tot i que el pes és petit, la longitud és massa llarga, la qual cosa provoca un fort tremolor del pal i és difícil de controlar. El pes lleuger i l'alta resistència dels materials compostos no només s'utilitzen en el grup de canyes de pescar, sinó també al final.
Patins de velocitat domèstics de fibra de carboni impresos en 3D:
3% - 4% de reducció de pes
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.
Moto de neu domèstica composta de fibra de carboni tg800 domèstica:
Baixeu el centre de gravetat per a més estabilitat
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.
Casc d'esquí:
El rendiment de protecció és almenys un 20 per cent superior a l'estàndard europeu
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
Cable calefactor de fibra de carboni:
La conversió directa redueix la pèrdua de calor
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.
Club d'hoquei sobre gel de fibra de carboni:
Durable i no fàcil de trencar
Els pals d'hoquei sobre gel de fibra de carboni utilitzats pels atletes són més duradors que els pals d'hoquei sobre gel normals després de l'aplicació d'un agent de formació de fluids. Segons el personal de RD, l'agent de formació de fluids de recobriment a la superfície del club d'hoquei de fibra de carboni pot augmentar la duresa del drap de fibra de carboni d'una banda i millorar la resistència estructural general del club, d'altra banda. En proporcionar un agent de formació de fluids de baixa fluïdesa, i quan la pressió d'inflat del motlle és constant, es pot assegurar que encara hi hagi prou agent de formació de fluids unit a la superfície del substrat de fibra de carboni del Club i participar en el procés de formació posterior. Un agent de formació de fluids suficient pot garantir la duresa del club d'hoquei, de manera que els jugadors no siguin fàcils de trencar o trencar el club quan es mou el club d'hoquei, assegureu-vos que el pal d'hoquei sigui fort i durador.
De fet, a més del creixement constant de la demanda de compostos de fibra de carboni en indústries tradicionals com ara esports i oci, aeroespacial, etc., el camp energètic dominat per la transmissió d'energia i l'energia eòlica i el camp del transport dominat pel transport d'automòbils i ferrocarril. també han injectat nova vitalitat al desenvolupament de la indústria de la fibra de carboni. L'economia verda i baixa-carboni té un efecte d'atracció important en l'aplicació de la fibra de carboni i també afavoreix que la indústria tèxtil industrial entri en una nova etapa d'aplicació industrial.
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.
