Nyob rau hauv kev loj hlob sai ntawm lub zog tauj dua tshiab, lub hnub ci zog yog ib qho kev cog lus zoo tshaj plaws rau kev tawm tsam kev hloov pauv huab cua thiab txo qis kev cia siab ntawm fossil fuels. Nyob rau hauv lub plawv ntawm lub hnub ci vaj huam sib luag technology yog ib qho tseem ceeb, feem ntau overlooked tivthaiv: ethylene vinyl acetate (EVA) zaj duab xis. Cov khoom siv ntau yam no ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm, ua haujlwm ntev, thiab kev ua haujlwm tag nrho ntawm cov hnub ci vaj huam sib luag, ua rau nws yog lub hauv paus ntawm lub hnub ci tshuab.
EVA zaj duab xisyog ib qho thermoplastic polymer dav siv hauv kev tsim cov hnub ci vaj huam sib luag. Nws lub luag haujlwm tseem ceeb yog encapsulate photovoltaic (PV) hlwb, tiv thaiv lawv los ntawm ib puag ncig yam xws li ya raws, plua plav, thiab kev ntxhov siab. Cov txheej txheem encapsulation no tseem ceeb heev vim nws ua kom lub neej ntev thiab kev ntseeg siab ntawm cov hnub ci vaj huam sib luag, uas feem ntau tsim los kav ntev li 25 xyoo lossis ntau dua. Yog tias tsis muaj EVA zaj duab xis, PV hlwb tsis yooj yim yuav raug cuam tshuam rau cov ntsiab lus, ua rau kev ua haujlwm tsis zoo thiab txo lub zog tso zis.
Ib qho txiaj ntsig tseem ceeb ntawm EVA zaj duab xis nyob hauv nws cov khoom tshwj xeeb kho qhov muag. Nws tshwj xeeb pob tshab maximizes nqus cov hnub ci uas ncav cuag lub hnub ci hlwb. Cov cuab yeej no yog qhov tseem ceeb rau kev txhim kho lub hnub ci vaj huam sib luag, vim tias txawm tias me ntsis txo qis hauv lub teeb xa hluav taws xob tuaj yeem cuam tshuam rau lub zog tsim hluav taws xob. Tsis tas li ntawd, EVA zaj duab xis qhov qis refractive index minimizes lub teeb pom kev zoo, ntxiv optimizing hloov dua siab tshiab ntawm hnub ci zog rau hauv hluav taws xob.
EVA zaj duab xis kuj muaj npe nrov rau nws cov khoom nplaum tshwj xeeb. Nws sib raug zoo rau ntau yam khoom siv, suav nrog iav thiab silicon, ua kom muaj lub zog ruaj khov, ruaj khov nyob ib puag ncig lub hnub ci. Qhov no adhesion yog ib qho tseem ceeb rau kev tiv thaiv cov dej noo infiltration, uas tuaj yeem ua rau corrosion thiab lwm yam kev puas tsuaj. EVA zaj duab xis tuav nws txoj kev ncaj ncees nyob rau lub sijhawm, txawm tias nyob rau hauv huab cua huab cua, ua kom pom nws qhov tseem ceeb hauv lub hnub ci vaj huam sib luag technology.
Lwm yam khoom tseem ceeb ntawm EVA zaj duab xis yog nws cov thermal stability. Hnub ci vaj huam sib luag feem ntau raug rau qhov kub thiab txias, thiab cov khoom siv hauv lawv cov kev tsim kho yuav tsum muaj peev xwm tiv taus cov xwm txheej no yam tsis muaj kev cuam tshuam rau kev ua haujlwm. EVA zaj duab xis tiv thaiv tshav kub zoo ua kom ntseeg tau tias cov cell photovoltaic encapsulated tiv thaiv thiab ua haujlwm kom zoo, txawm tias nyob hauv huab cua kub tshaj plaws. Cov cuab yeej no muaj txiaj ntsig tshwj xeeb rau kev teeb tsa hnub ci hauv thaj chaw uas muaj hnub ci hluav taws xob siab thiab muaj peev xwm ua kom sov siab.
Tshaj nws cov khoom tiv thaiv, EVA zaj duab xis txhim kho tag nrho kev zoo nkauj ntawm hnub ci vaj huam sib luag. Lub pob tshab zaj duab xis muab lub hnub ci vaj huam sib luag ua kom zoo nkauj, niaj hnub saib, ua rau lawv txaus nyiam rau ob lub tsev thiab kev lag luam. Raws li kev thov rau lub hnub ci zog txuas ntxiv zuj zus, cov tsos ntawm lub hnub ci thev naus laus zis tau dhau los ua qhov tseem ceeb hauv kev txhawb nqa nws.
Raws li kev lag luam hnub ci txuas ntxiv tsim kho tshiab, EVA zaj duab xis tseem tseem ceeb heev. Cov kws tshawb fawb tab tom tshawb nrhiav cov qauv tshiab thiab kev txhim kho ntxiv los txhim kho nws cov kev ua tau zoo, xws li txhim kho UV tiv thaiv thiab txo nws qhov cuam tshuam ib puag ncig. Cov kev nce qib no yuav ua kom ntseeg tau tias EVA zaj duab xis txuas ntxiv ua kom tau raws li cov kev xav tau ntawm lub hnub ci thev naus laus zis thiab ua rau lub ntiaj teb hloov pauv mus rau lub zog ruaj khov.
Hauv cov ntsiab lus,EVA zaj duab xisyog undoubtedly lub hauv paus ntawm lub hnub ci vaj huam sib luag technology. Nws cov kev tiv thaiv zoo heev, kho qhov muag, nplaum, thiab cov khoom siv thermal ua rau nws yog ib qho tseem ceeb hauv kev tsim cov hnub ci vaj huam sib luag thiab ruaj khov. Raws li lub ntiaj teb hloov mus rau cov kev daws teeb meem hluav taws xob tauj dua tshiab, qhov tseem ceeb ntawm EVA zaj duab xis hauv kev ua kom lub hnub ci thev naus laus zis tsis tuaj yeem ua dhau los. Nws ua lub luag haujlwm tseem ceeb hauv kev ua kom lub neej ntev thiab kev ua haujlwm ntawm cov hnub ci vaj huam sib luag, uas yuav txuas ntxiv tsav peb txoj kev ua kom huv huv, muaj kev nyab xeeb dua yav tom ntej.
