Tuam Tshoj txoj kev loj hlob ntawm lub zog huv si thiab kev txhawb nqa ntawm ntsuab thiab qis-carbon kev lag luam thiab kev hloov pauv hauv zej zog tau dhau los ua kev pom zoo thoob ntiaj teb hauv zej zog los daws cov kev hloov pauv huab cua thoob ntiaj teb. Peb yuav tsum ua raws li tus qauv thiab coj kom zoo dua ntawm nws, thiab siv zog ntau dua los txhawb txoj kev loj hlob zoo ntawm lub zog tshiab hauv Suav teb, muab kev nyab xeeb thiab txhim khu kev qha lub zog ruaj ntseg rau Suav txoj kev mus rau niaj hnub, thiab ua kom muaj txiaj ntsig zoo rau kev tsim kom muaj kev huv thiab zoo nkauj. ntiaj teb ua ke.
Raws li ib qho ntawm cov chaw kub tshaj plaws nyob rau tam sim no, kev lag luam hluav taws xob tshiab tuaj yeem daws teeb meem ntawm lub zog ntawm lub teb chaws yav tom ntej, thiab nws txoj kev loj hlob muaj peev xwm loj heev. Kev lag luam cov ntaub ntawv sib xyaw yog ib qho tseem ceeb ntawm kev lag luam tawm tswv yim txhawb los ntawm lub xeev. Txij li xyoo 2000, lub xeev tau tshaj tawm ntau txoj cai kev lag luam los txhawb kev txhim kho cov khoom siv sib xyaw. Lub National Development thiab Reform Commission, Ministry of Science thiab Technology, Ministry of Industry thiab Information Technology thiab lwm lub tuam tsev tau txhawb nqa lawv.
Xyoo 2022, Ministry of Industry thiab Information Technology, Ministry of Science thiab Technology, thiab Ministry of Natural Resources tau koom ua ke tshaj tawm "14th Tsib Xyoo Plan" rau kev txhim kho cov khoom siv raw khoom, uas qhia meej meej tias: "Txhim kho kev nthuav dav. kev sib tw ntawm kev tsim cov khoom siv qib siab xws li steel, muaj zog aluminium alloys, cov khoom siv hlau tsis tshua muaj nqi, tshwj xeeb engineering plastics, cov ntaub ntawv ua yeeb yaj kiab zoo, cov ntaub ntawv fiber ntau, cov ntaub ntawv sib xyaw, thiab lwm yam. "
Composite photovoltaic brackets usher hauv cov cib fim tshiab
Raws li cov khoom txhawb nqa ntawm kev lag luam photovoltaic saw, kev nyab xeeb, kev siv tau, thiab kev ua haujlwm ntev ntawm lub hnub ci photovoltaic brackets tau dhau los ua cov ntsiab lus tseem ceeb rau kev pabcuam kev nyab xeeb ntawm cov tshuab photovoltaic thaum lub sijhawm tsim hluav taws xob.
Tam sim no, cov khoom siv ntawm lub hnub ci photovoltaic brackets yog cov hlau hnyav, feem ntau siv cov ntaub ntawv xws li kub-dip galvanized steel, stainless hlau, thiab aluminium alloy. Hnub ci cell modules feem ntau ntsia sab nraum zoov, yog li cov khoom siv ib txwm muaj feem xyuam rau corrosion, xeb, thiab ntsev puas. Nyob rau tib lub sijhawm, thaum sib sau ua ke ntau lub modules, qhov hnyav hnyav nqa ntau qhov tsis yooj yim rau kev teeb tsa. Yog li ntawd, lub durability thiab lub teeb yuag ntawm lub bracket yog yav tom ntej tiam sis.
Nyob rau hauv xyoo tas los no, cov yam ntxwv ntawm resin raws li cov ntaub ntawv sib xyaw, xws li lub teeb yuag, siab zog, corrosion kuj, kev laus tsis kam, zoo hluav taws xob rwb thaiv tsev, thiab cov khoom anisotropy, tau maj mam lees paub los ntawm tib neeg. Nrog rau kev sib sib zog nqus ntawm kev tshawb fawb ntawm cov ntaub ntawv sib xyaw, lawv cov ntawv thov tau dhau los ua ntau dua.
Cov ntaub ntawv sib xyaw tau dhau los ua cov ntaub ntawv tseem ceeb hauv kev ua haujlwm ntawm lub zog cua
Raws li ib qho tseem ceeb kawg kev lag luam rau cov ntaub ntawv sib xyaw, cua zog yog tam sim no ib qho ntawm cov kev xav tau loj tshaj plaws rau cov iav fiber ntau thiab carbon fiber. Txoj kev loj hlob ntawm lub tshuab hluav taws xob tsim kev lag luam ncaj qha cuam tshuam rau kev lag luam loj ntawm cov khoom siv sib xyaw ua lag luam, uas cuam tshuam rau cov nyiaj tau los ntawm cov lag luam.
Tawm tsam keeb kwm yav dhau los ntawm lub ntiaj teb lub zog qauv hloov mus rau qis-carbon thiab kev ua kom zoo ntawm lub zog tas li
kev siv cov qauv, qhov sib txawv ntawm kev loj hlob nyob rau hauv kev thov rau lub zog tauj dua tshiab yog qhov tseeb. Cua zog, nrog nws cov peev txheej zoo tshaj plaws thiab kev txhim kho zoo xws li cov peev txheej tag nrho, kev tiv thaiv ib puag ncig, qib siab ntawm kev ua haujlwm thiab kev tswj hwm automation, thiab kev txo qis ntawm hluav taws xob tas li, tau dhau los ua ib qho kev tsim thiab siv hluav taws xob txuas ntxiv. . Nws yog ib qho tseem ceeb ntawm lub ntiaj teb kev siv hluav taws xob tauj dua tshiab thiab kev siv, thiab nws txoj kev loj hlob yog maj mam hloov ntawm lub zog ntxiv mus rau lwm lub zog. Nws daim ntawv thov yog ib qho tseem ceeb tsav lub zog rau kev txhawb zog qauv optimization thiab tsawg-carbon zog, thiab yog ib tug ntawm cov tseem ceeb txoj kev mus cuag lub hom phiaj ntawm "carbon ncov" thiab "carbon neutrality".
Cua turbine blades yog tsim los ntawm resin matrix (36%), cov khoom siv ntxiv (28%), cov khoom siv tseem ceeb (12%), nplaum (11%), thiab lwm yam. cov khoom siv fiber ntau txhawb nqa tsuas yog muab qhov nruj thiab lub zog ntawm cov qauv hniav. Cov khoom siv fiber ntau muaj xws li iav fiber ntau thiab carbon fiber, thiab lwm yam. Cov ntaub ntawv sib xyaw muaj qhov zoo sib xws hauv kev muaj zog tshwj xeeb thiab cov qauv tshwj xeeb, ua rau lawv nyiam cov khoom siv rau cov cua turbine loj tam sim no. Cov ntaub ntawv sib xyaw feem ntau suav txog ntau dua 90% ntawm qhov hnyav hauv tag nrho cov cua turbine hniav. Cov qauv load-bearing yog tsim los ntawm iav fiber ntau lossis carbon fiber ntau cov ntaub ntawv, uas ua rau cov qauv muaj zog txhua yam khoom. Cov khoom siv sib xyaw ua ke feem ntau yog tsim los ntawm peb qhov chaw: hauv paus, plhaub, thiab kev txhawb nqa tav lossis kab teeb. Piv nrog rau tib theem ntawm siab modulus fiberglass lub ntsiab kab teeb, siv cov pa roj carbon fiber ntau tuaj yeem ua tiav qhov hnyav ntawm 20-30%. Siv 122m ntev hniav ua piv txwv, txo qhov hnyav ntawm cov hniav tuaj yeem txo cov load xa mus rau lub cav tseem ceeb vim nws qhov hnyav, yog li txo qhov hnyav ntawm cov khoom siv xws li hubs, cav chav, yees, thiab pawg hauv paus. los ntawm 15% mus rau 20%, zoo txo tus nqi tag nrho ntawm tus kiv cua ntau dua 10%. Tsis tas li ntawd, lub zog tso tawm ntawm lub kiv cua yog qhov ruaj khov thiab sib npaug, thiab kev ua haujlwm tau zoo dua. Vim lub siab qaug zog ntawm cov pa roj carbon fiber ntau, nws tuaj yeem txuas ntxiv lub neej voj voog ntawm cov hniav thiab txo cov nqi xws li cov nqi tu txhua hnub.
