Hauv Beijing Olympics 2022, cov khoom siv tshuaj tshiab twg yog siv?

Views:323 Author: Dej Hiav Txwv Tshaj Tawm Sijhawm: 2022-02-07 keeb kwm:

 Nyob rau yav tsaus ntuj ntawm Lub Ob Hlis 4, ib xyoos suav rov qab rau Beijing Lub Caij Nplooj Ntoos Hlav Olympic tau tuav ntawm "Ice Cube" ntawm National Aquatics Center. Kev tsim sab nrauv ntawm lub teeb rau Beijing 2022 Winter Olympics thiab Paralympic Winter Games tau raug tso tawm.

    Tag nrho cov tsos ntawm lub teeb echoes cov duab ntawm lub ntsiab teeb pom kev zoo nyob rau hauv lub qhib ceremony ntawm lub Beijing 2008 Olympic ua si. Lub teeb yog "raws li" nrog cov qauv huab cua zoo, uas maj mam hloov ntawm huab cua zoo nkauj mus rau daim ntawv-txiav style snowflake qauv los ntawm hauv qab mus rau sab saum toj, thiab tig thiab nce zoo li ribbon fluttering. Wang Xiangyu, tus lwm thawj coj ntawm Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm ntawm Kab lis kev cai ntawm Beijing Lub Caij Nplooj Ntoos Hlav Lub Caij Ntuj Sov, tau hais tias lub teeb ntawm 2022 Lub Caij Ntuj Sov Olympics qhia txog kev sib koom ua ke zoo tshaj plaws ntawm kev tsim duab kos duab thiab thev naus laus zis tshiab.

Beijing 2022 Lub caij ntuj no Paralympics Torch


Carbon fiber hloov cov khoom siv hlau tsoos

   Lub caij ntuj no Olympic torches yav dhau los, suav nrog lub teeb Olympic, tau ua los ntawm cov khoom siv hlau tsoos. Lub plhaub "Flying" yog tsim los ntawm lub teeb yuag, siab-kub-resistant carbon fiber cov khoom, thiab lub teeb combustion tank kuj tseem ua los ntawm cov khoom siv fiber ntau.

     Raws li Huang Xiangyu, tus kws tshaj lij carbon fiber thiab lwm tus thawj tswj hwm ntawm Sinopec Shanghai Petrochemical Co., Ltd., Beijing Winter Olympics teeb yog tsim los ntawm lub plhaub thiab cov khoom siv hluav taws xob. Lub teeb lub plhaub yog ua los ntawm cov roj carbon fiber ntau thiab nws cov khoom sib xyaw, uas qhia txog "lub teeb, khoom, kev zoo nkauj" yam ntxwv.

--- "Lub teeb": Piv nrog tib lub ntim ntawm aluminium alloy, cov khoom siv carbon fiber ntau yog ntau dua 20% sib dua.

--- "Cov khoom": Cov khoom muaj cov yam ntxwv ntawm lub zog siab, corrosion kuj, kub tsis kam, kev sib txhuam tsis kam, ultraviolet hluav taws xob tiv thaiv thiab lwm yam.

--- "Kev zoo nkauj": Lub thoob ntiaj teb advanced peb-dimensional peb-dimensional weaving molding tshuab yog siv rau kev ua haujlwm siab fibers rau hauv ib qho zoo nkauj tag nrho nrog cov duab nyuaj.

   Cov tsev kawm ntawv qib siab, cov koom haum tshawb fawb thiab cov tuam txhab kev tshawb fawb thiab thev naus laus zis tau ua haujlwm ua ke los daws cov teeb meem ntau, daws cov ntawv thov fwj ntawm carbon fiber ntau cov ntaub ntawv nyob rau hauv cov xwm txheej hnyav, thiab paub txog kev siv lub teeb ci hauv ib puag ncig hydrogen combustion saum 800. °C. Nws daws tau cov teeb meem ntawm foaming thiab cracking ntawm lub teeb lub plhaub thaum lub sij hawm kub npaj txheej txheem ntawm 1000 °C.


   Huang Xiangyu tau hais tias kev siv cov khoom siv sib xyaw carbon fiber ntau rau torches tau ua tiav kev tsim kho tshiab hauv 3 yam:

1, 3D weaving txoj kev

Nws tuaj yeem npaj tau ntau yam duab, thiab tuaj yeem npaj raws li qhov loj me ntawm tus tsim qauv. Qhov no yog ib qho kev sib tw hauv cov pa roj carbon fiber molding.

2, Pwm tsim

Kev tsim cov pwm tsim siv cov pwm sib xyaw ua ke los daws cov kev xav tau ntawm qhov sib txawv nkhaus.

3, Kub kub resin

Ib qho tshwj xeeb resin uas tuaj yeem tiv taus qhov kub thiab txias yog xaiv. Tsis tas li ntawd, cov tshuab moulding tshuab kuj tshwj xeeb tsim rau cov khoom siv no.

Siv hydrogen ua roj kom kov yeej peb qhov teeb meem loj.


    Han Zongjie, tus kws tshaj lij ntawm Tuam Tshoj Aerospace Science thiab Technology Corporation, tau tshaj tawm tias kev txhim kho lub teeb pom kev zoo tau daws ntau yam teeb meem xws li nplaim xim thiab kev ruaj ntseg, kev kub siab hydrogen cia, thiab kev nyab xeeb siv hydrogen zog. Kev nyab xeeb thiab kev ntseeg siab, cua tsis kam 10, tuaj yeem siv rau hauv huab cua txias heev, qhov sib piv decompression yog siab li ntau pua zaus. Thaum daws teeb meem nyuaj, nws kuj yuav siv sij hawm rau hauv tus account qhov yuav tsum tau ntawm lub teeb yuag thiab miniaturized zoo sib xws. 


      Thawj yog xim ntawm nplaim taws. Cov nplaim hluav taws ntawm hydrogen tsis pom nyob rau hauv tshav ntuj, uas tsis txaus rau kev tua. Pab neeg tshawb fawb tau tsim cov qauv uas tuaj yeem kho cov xim ntawm cov nplaim hluav taws xob kom nws pom cov nplaim xim nyob rau hauv tshav ntuj.


    Qhov thib ob yog qhov ruaj khov ntawm cov nplaim taws. Thaum lub teeb hluav taws xob relay, cua muaj zog tuaj yeem ntsib, thiab pab pawg tshawb fawb tau daws qhov teeb meem ntawm cov nplaim hluav taws xob ruaj khov ntawm lub teeb nyob rau hauv cua ceev ntawm 100 km / h.

 

     Ib zaug ntxiv, muaj qhov teeb meem ntawm high-pressure hydrogen cia. Yuav ua li cas loj scale decompression? Nyob rau hauv lub teeb, qhov chaw me me heev. Nyob rau hauv xws li ib qho chaw, yuav ua li cas kom ua tau ib tug loj decompression mus txog rau ob peb puas lub sij hawm yog ib qho teeb meem nyuaj heev. Pab neeg no tsim lub teeb yuag thiab miniaturized hydrogen decompression ntaus ntawv los decompress high-pressure hydrogen.
