Let's look at the new materials inside and outside the Winter Olympics
1. Lub teeb ntawm lub caij ntuj no Olympic ua si yog ua los ntawm carbon fiber
Beijing Lub caij ntuj no Olympic teeb tau ua nws thawj zaug ntawm thawj hnub tseem ceeb ntawm kev suav rov qab rau kev qhib lub koob tsheej ntawm Beijing Lub caij ntuj no Olympic ua si!
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. Txhaum ntau yam kev tsis sib haum xeeb
Txhawm rau siv cov pa roj carbon fiber ntau hauv lub teeb, los ntawm kev sib koom ua ke ntawm ntau tog neeg, daim ntawv thov lub fwj ntawm cov pa roj carbon fiber ntau nyob rau hauv cov xwm txheej txias tau ua tiav tiav, kev siv lub plhaub ntawm lub plhaub hauv hydrogen combustion ib puag ncig siab dua 800 degree. paub, thiab cov teeb meem xws li blistering thiab tawg ntawm lub teeb lub plhaub thaum lub sij hawm siab -kub npaj ntawm 1000 degree tau raug daws.
3. Siv hydrogen ua roj los daws teeb meem
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.
Muaj ib txwm muaj ntau yam teeb meem hauv cov txheej txheem tshawb fawb ntawm lub teeb, tab sis los ntawm kev siv zog tsis tu ncua ntawm pab pawg tshawb fawb, ntau yam teeb meem xws li nplaim xim thiab kev ruaj ntseg, siab - siab hydrogen cia, kev nyab xeeb siv hydrogen zog thiab lwm yam. ntawm tau ua tiav tiav.
Cov nplaim hluav taws muaj kev nyab xeeb thiab kev ntseeg siab, tuaj yeem tiv taus cua theem 10, tuaj yeem siv rau huab cua txias heev, thiab qhov sib piv decompression yog mus txog ntau pua zaus. Thaum daws teeb meem nyuaj, nws yuav siv sij hawm rau hauv tus account qhov yuav tsum tau ntawm lub teeb yuag thiab miniaturization zoo sib xws.
Cov khoom siv ua kis las
No matter what kind of sports, a suitable sportswear is particularly important for athletes and can improve athletes' performance to some extent.
1. Ceev skating haiv neeg ce
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. Ski kaus mom hlau
Kev caij ski yog ib qho kev ua si zoo nkauj tshaj plaws skiing, uas ua ke nrog kev ceev thiab kev txawj ntse. Cov neeg ncaws pob yuav tsum ua kom tiav qhov nqis sai sai thiab kev sib hloov ntawm qhov chaw siab tshaj ntawm toj roob hauv pes snow.
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.
Tshiab shock absorber
Rau cov kev ua si daus, yog tias qib ntawm cov neeg ncaws pob zoo ib yam, qhov cuam tshuam rau kev ua haujlwm tsis yog tsuas yog cov khoom siv hauv cov khoom siv xwb, tab sis kuj muaj kev vibration.
Qhov kev vibration tuaj yeem ua rau hauv qab ntawm lub sled kom thaws tawm ntawm cov daus saum npoo, uas txo cov kev tswj thiab kev ua haujlwm ntawm cov neeg ncaws pob thiab txwv qhov zawv zawg ceev. Yog li ntawd, nyob rau hauv cov xwm txheej skiing, nws yog ib qho tsim nyog yuav tsum ua kom lub sled ze rau ntawm cov daus saum npoo los ntawm kev siv tshuab damping, thiaj li ua rau kom muaj zog, tswj thiab ceev ntawm cov neeg ncaws pob. Lub hauv paus ntawm kev poob siab absorbing technology yog los txo qhov kev sib kis ntawm kev co zog los ntawm lub zog dissipation yam ntxwv ntawm shock absorbers.
