Let's look at the new materials inside and outside the Winter Olympics
1. Tá tóirse Cluichí Oilimpeacha an Gheimhridh déanta as snáithín carbóin
Thosaigh tóirse Oilimpeach an Gheimhridh Beijing ar chomóradh céad bliain an chomhairimh síos go searmanas oscailte Chluichí Oilimpeacha an Gheimhridh i mBéising!
The overall appearance of the torch echoes the shape of the main torch tower at the opening ceremony of the Beijing 2008 Olympic Games. The torch is "bottomed out" with auspicious cloud patterns, and gradually transits from auspicious cloud patterns to paper-cut style snowflakes from bottom to top. It rotates and rises like ribbons, reflecting the perfect integration of artistic design and scientific and technological innovation.
The torch is usually made of traditional metal materials, including the summer Olympic torch, but the shell of the 2022 Winter Olympic torch is made of light-weight high-temperature resistant carbon fiber materials and composite materials. The torch combustion tank is also made of carbon fiber materials, which is characterized by "light, solid and beautiful".
2. Crack baic theicniúla iolracha
D'fhonn comhdhúile snáithíní carbóin a úsáid sa tóirse, trí iarrachtaí comhbheartaithe go leor páirtithe, tá an tranglam iarratais ar chomhchodanna snáithíní carbóin faoi choinníollacha fuar a réiteach go rathúil, tá gnáthúsáid bhlaosc tóirse i dtimpeallacht dócháin hidrigine níos airde ná 800 céim. réadaithe, agus tá na fadhbanna ar nós blistering agus scoilteadh an bhlaosc tóirse le linn ullmhúcháin ardteochta ag 1000 céim réitithe.
3. Hidrigin a úsáid mar bhreosla le fadhbanna a réiteach
Adhering to the concept of "Green Olympics", the Beijing Winter Olympic Games adopts clean and environment-friendly hydrogen fuel in the selection of torch fuel.
Bíonn fadhbanna éagsúla i bpróiseas taighde an tóirse i gcónaí, ach trí iarrachtaí gan staonadh na foirne taighde, tá go leor fadhbanna teicniúla cosúil le dath lasair agus cobhsaíocht, stóráil hidrigine ardbhrú, úsáid shábháilte fuinnimh hidrigine agus mar sin de. ar a bheith réitithe go rathúil.
Tá sábháilteacht agus iontaofacht ard ag an lasair, is féidir leis seasamh in aghaidh leibhéal na gaoithe 10, is féidir é a úsáid i aimsir an-fhuar, agus tá an cóimheas dí-chomhbhrú suas leis na céadta uair. Agus fadhbanna casta á réiteach, cuireann sé san áireamh na ceanglais a bhaineann le meaitseáil cruth éadrom agus miniaturization.
Trealamh éadaí spóirt
No matter what kind of sports, a suitable sportswear is particularly important for athletes and can improve athletes' performance to some extent.
1. Culaith rása scátáil luais
As an official event in the Winter Olympic Games, short track speed skating has always attracted much attention. Speed skating competition clothes will choose a rubber material with dozens of times stronger elasticity than ordinary fiber in the thigh, which can zuida reduce physical consumption to a certain extent; In the right crotch position, a synthetic fiber will be used, which can effectively reduce friction; In order to reduce air resistance, honeycomb polyurethane materials are used in the hands and feet of speed skating competition clothes. These materials are selected to best improve athletes' performance.
2. Clogad sciála
Is spórt sciála an-ornáideach é an sciáil, a chomhcheanglaíonn luas agus scileanna go horgánach. Ba chóir do lúthchleasaithe a shliocht tapa agus rothlú a chur i gcrích ar na fánaí géara na sléibhte sneachta arda.
When skiing, athletes' heads will emit a lot of heat, so they need to wear breathable and warm helmets. The shell of ski helmet is mainly made of PC (polycarbonate) and ABS (a kind of engineering plastic). The inner shell is generally made of high-density foam material, which can play the best cushioning role after the head is impacted.
ionsúire turrainge nua
Maidir le spóirt sneachta, má tá leibhéal na lúthchleasaithe mar an gcéanna, is é an fachtóir a dhéanann difear don fheidhmíocht, ní hamháin na hábhair a úsáidtear sa trealamh, ach freisin an tonnchrith.
Féadfaidh an tonnchrith a bheith ina chúis le bun an sled preabadh as an dromchla sneachta, rud a laghdaíonn rialú agus imoibríocht na lúthchleasaithe agus a chuireann teorainn ar an luas sleamhnáin. Dá bhrí sin, in imeachtaí sciála, is gá an sled a dhéanamh gar don dromchla sneachta trí theicneolaíocht damping, ionas go n-ardófar imoibríocht, rialú agus luas na lúthchleasaithe. Is é croílár na teicneolaíochta ionsú turraing ná tarchur fuinnimh creathadh a laghdú trí shaintréithe diomailt fuinnimh na n-ionsúire turraing.
