Polyurethane, polyester cob, carbon fiber thiab lwm yam ntaub ntawv tshiab hniav yog tas li tshwm sim, thiab innovation txheej txheem ntawm kiv cua cov ntaub ntawv yog obviously ceev.Tsis ntev los no, cov hniav chaw tsim tshuaj paus Zhuzhou Times New Materials Technology Co., Ltd. (tom qab no hu ua "Times New Materials") thiab cov khoom siv Kostron tshaj tawm tias 1000th polyurethane resin ntxuam hniav tau raug dov tawm ntawm cov kab sib dhos, tsim kom muaj ib qho precedent rau batch zus tau tej cov polyurethane resin hniav.

Nyob rau hauv xyoo tas los no, Tuam Tshoj txoj kev lag luam cua fais fab yog tsim los ntawm kev kub ceev.Lub teeb, loj dua thiab ruaj khov cua turbine hniav tau dhau los ua qhov kev txhim kho tseem ceeb.Dhau li ntawm polyurethane resin, cov ntaub ntawv hniav tshiab xws li polyester resin thiab carbon fiber tau tshwm sim tas li, thiab cov txheej txheem tshiab ntawm cov khoom siv cua turbine hniav tau pom tseeb nrawm dua.
Lub permeability ntawm polyurethane hniav yog txhim kho.
Nws yog to taub tias nyob rau hauv ib txwm muaj xwm txheej, kiv cua hniav yog tsim los ntawm resin, reinforced fibers thiab cov ntaub ntawv tseem ceeb.Tam sim no, epoxy resin yog lub ntsiab resin siv nyob rau hauv cov txheej txheem ntawm cov kiv cua.Xav txog cov nqi resin, kev tsim khoom, kev siv dua tshiab thiab lwm yam, cov tuam txhab kiv cua tseem tab tom nrhiav lwm yam kev daws teeb meem.Ntawm lawv, piv nrog cov khoom siv tshuaj epoxy resin, cov ntaub ntawv polyurethane resin muaj qhov zoo ntawm kev kho kom yooj yim dua thiab muaj zog dua, thiab raug suav tias yog ib tiam tshiab ntawm cov khoom siv cob rau cov kiv cua los ntawm kev lag luam.
"Polyurethane resin yog cov khoom siv polymer ua haujlwm siab.Ntawm qhov tod tes, qhov toughness thiab qaug zog tsis kam ntawm polyurethane resin yog qhov zoo, ua tau raws li qhov xav tau ntawm cov kiv cua;Ntawm qhov tod tes, piv nrog epoxy resin, tus nqi ntawm polyurethane resin kuj muaj qee qhov zoo, thiab cov nqi ua haujlwm tau zoo dua.” Feng Xuebin, R & D Tus Thawj Coj ntawm Cov Khoom Siv Tshiab Cua Hluav Taws Xob Khoom Siv Hluav Taws Xob, tau hais hauv kev xam phaj.
Nyob rau tib lub sijhawm, Costron kuj tau taw qhia hauv nws cov khoom qhia tias polyurethane resin ntxuam hniav muaj cov khoom siv zoo dua qub, kev tsim khoom nrawm dua, thiab muaj qee yam kev lag luam sib tw, thiab tus nqi nkag mus rau hauv cov kiv cua ntawm lub khw muag khoom kuj tau pib nce.
Txog tam sim no, Lub Sijhawm Tshiab Cov Khoom Siv tau tsim ntau hom polyurethane resin ntxuam hniav, nrog qhov ntev ntawm 59.5 meters txog 94 meters.Cov hniav tsim thiab txheej txheej kuj txawv.Ntawm lawv, 94-meter hniav tuaj yeem siv rau lub kiv cua nrog ib lub zog ntawm 8 megawatts.Nws tau nkag siab tias polyurethane resin cov hniav tau nkag mus rau theem ntawm kev lag luam daim ntawv thov thiab tau muab tso rau hauv ntau lub teb chaws cua.
Cov khoom siv tshiab ntawm cov hniav yog pom tseeb nrawm.
Qhov tseeb, dhau li ntawm polyurethane resin, nyob rau hauv xyoo tas los no, lwm yam kev tshawb fawb tshiab ntawm cov khoom siv ntawm cov kiv cua hauv tsev thiab txawv teb chaws tau tshwm sim tas li.Cov khoom tseem ceeb ntawm Danish ntxuam hniav chaw tsim tshuaj paus LM yog polyester cob thiab iav fiber.Raws li lub tuam txhab cov ntaub ntawv lub vev xaib, tom qab ntau zaus ntawm kev tsim kho thiab kev ua kom zoo, lub tuam txhab polyester resin kiv cua cov hniav tau rov ua dua lub ntiaj teb cov kiv cua ntev tshaj plaws cov ntaub ntawv.
Kev saib xyuas ntau dua tau them rau carbon fiber ua qhov hloov tshiab rau iav fiber ntau.Raws li qhov yuav tsum tau ua ntawm lub teeb yuag kiv cua, cov pa roj carbon fiber tau nyiam los ntawm kev lag luam rau nws cov khoom siv muaj zog.Tsuas yog lub xyoo no, ntawm cov tuam txhab tsim khoom hauv tsev, cov kiv cua tau qhia los ntawm cov kiv cua tseem ceeb xws li Goldwind Technology, Yunda, Mingyang Intelligent, thiab lwm yam. txhua tus txais yuav cov hniav nrog carbon fiber li reinforcing fiber.
Feng Xuebin tau hais rau cov neeg sau xov xwm tias tam sim no, kev tsim kho tshiab thiab kev tsim kho cov khoom siv cua turbine hniav yog tsom rau peb cov lus qhia.Ua ntej, nyob rau hauv lub siab ntawm cua zog parity, hniav ntau lawm muaj ntau dua tus nqi tswj yuav tsum tau, yog li ntawd nws yog tsim nyog los nrhiav cov ntaub ntawv hniav nrog tus nqi siab dua.Qhov thib ob, cov hniav yuav tsum tau hloov kho kom haum rau qhov chaw tsim hluav taws xob cua.Piv txwv li, txoj kev loj hlob loj ntawm ntug dej hiav txwv cua fais fab yuav txhawb kev siv cov ntaub ntawv zoo xws li cov pa roj carbon fiber ntau hauv cov hniav.Qhov thib peb yog los daws qhov kev tiv thaiv ib puag ncig xav tau ntawm cov hniav.Kev rov ua dua ntawm cov ntaub ntawv sib xyaw ntawm cov cua turbine hniav ib txwm yog ib qho teeb meem nyuaj hauv kev lag luam.Vim li no, kev lag luam tseem tab tom nrhiav ib qho khoom siv rov ua dua tshiab thiab ruaj khov.
Cov ntaub ntawv tshiab los yog cov cuab yeej cua hluav taws xob txo nqi.
Nws yog ib nqi sau cia hais tias ib tug xov tooj ntawm kev lag luam insiders hais rau reporters hais tias cua turbine hniav kev lag luam tab tom ntsib kev nyuaj siab ntawm tus nqi txo nyob rau hauv lub tam sim no qhov teeb meem ntawm sai poob nqi ntawm cua turbines.Yog li ntawd, kev tsim kho tshiab ntawm cov ntaub ntawv hniav yuav dhau los ua riam phom zoo los txhawb cov cua fais fab txo nqi.
Cinda Securities, lub koom haum tshawb fawb kev lag luam, tau taw qhia hauv nws cov ntaub ntawv tshawb fawb hais tias nyob rau hauv tus nqi qauv ntawm cov cua turbine hniav, tus nqi ntawm raw cov ntaub ntawv suav txog 75% ntawm tag nrho cov nqi tsim khoom, thaum ntawm cov khoom siv raw, tus nqi ntawm cov khoom siv fiber ntau. thiab resin matrix account rau 21% thiab 33% feem, uas yog ib feem tseem ceeb ntawm tus nqi ntawm raw khoom rau cua turbine hniav.Nyob rau tib lub sijhawm, cov neeg hauv kev lag luam kuj tau hais rau cov neeg sau xov xwm tias cov hniav nyiaj hniav kub yog kwv yees li 25% ntawm tus nqi ntawm cov kiv cua, thiab tus nqi txo cov khoom siv hniav yuav ua rau cov nqi tsim khoom ntawm cov kiv cua.
Cinda tau taw qhia ntxiv tias nyob rau hauv cov qauv ntawm cov cua turbines loj, kev ua kom zoo ntawm cov khoom siv kho tshuab, lub teeb yuag thiab tus nqi txo yog qhov kev hloov pauv ntawm cov tshuab cua turbine hniav tam sim no, thiab nws txoj kev paub yuav ua kom zoo dua ntawm cov khoom siv cua turbine hniav, kev tsim cov txheej txheem thiab cov qauv hniav, qhov tseem ceeb tshaj plaws yog qhov iteration ntawm cov khoom sab.
"Rau lub hom phiaj sib luag, kev tsim kho tshiab ntawm cov ntaub ntawv hniav yuav ua rau kev lag luam txo cov nqi los ntawm peb yam hauv qab no.Ua ntej, tus nqi ntawm cov khoom siv hniav nws tus kheej txo qis;thib ob, lub teeb yuag hniav yuav txhawb kev txo qis ntawm cov cua turbine load, yog li txo cov nqi tsim khoom;Thib peb, cov cua turbine hniav xav tau cov ntaub ntawv ua tau zoo dua kom hloov mus rau qhov sib txawv ntawm cov cua turbine loj, yog li paub txog qhov txo cov nqi hluav taws xob."Feng Xuebin hais.
Nyob rau tib lub sijhawm, Feng Xuebin kuj tau ceeb toom tias nyob rau xyoo tas los no, kev lag luam cua tshuab hluav taws xob hauv tsev tau nrawm nrawm, uas tau txhawb txoj kev loj hlob sai ntawm kev lag luam.Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm txoj kev loj hlob, kev lag luam yuav tsum tau them nyiaj ntau dua rau kev ntseeg siab ntawm cov thev naus laus zis tshiab, txo cov kev pheej hmoo ntawm kev siv thev naus laus zis tshiab, thiab txhawb kev txhim kho zoo ntawm tag nrho kev lag luam.
