Hauv kev lag luam fais fab uas loj hlob sai sai, lub zog hnub ci yog ib qho ntawm cov kev daws teeb meem zoo tshaj plaws rau kev tawm tsam kev hloov pauv huab cua thiab txo kev vam khom roj av. Lub plawv ntawm cov thev naus laus zis hnub ci muaj ib qho tseem ceeb, feem ntau tsis quav ntsej: ethylene vinyl acetate (EVA) zaj duab xis. Cov khoom siv ntau yam no ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo, kev ruaj khov, thiab kev ua tau zoo ntawm cov hnub ci, ua rau nws yog lub hauv paus ntawm cov thev naus laus zis hnub ci.
EVA zaj duab xisyog ib qho thermoplastic polymer siv dav hauv kev tsim cov vaj huam sib luag hnub ci. Nws lub luag haujlwm tseem ceeb yog los encapsulate photovoltaic (PV) cells, tiv thaiv lawv los ntawm cov yam ntxwv ib puag ncig xws li dej noo, plua plav, thiab kev ntxhov siab ntawm lub tshuab. Cov txheej txheem encapsulation no yog qhov tseem ceeb vim nws ua kom lub neej ntev thiab kev ntseeg siab ntawm cov vaj huam sib luag hnub ci, uas feem ntau tsim los kav ntev li 25 xyoo lossis ntau dua. Yog tsis muaj zaj duab xis EVA, cov PV cells uas tsis muaj zog yuav raug rau cov huab cua, ua rau kev ua haujlwm poob qis thiab txo qis zog tso zis.
Ib qho txiaj ntsig tseem ceeb ntawm zaj duab xis EVA yog nws cov khoom siv kho qhov muag zoo heev. Nws qhov kev pom tseeb tshwj xeeb ua rau lub hnub ci nqus tau zoo tshaj plaws. Cov yam ntxwv no yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm ntawm lub hnub ci vaj huam sib luag, vim tias txawm tias qhov txo qis me ntsis ntawm kev xa hluav taws xob tuaj yeem cuam tshuam rau kev tsim hluav taws xob. Ntxiv mus, zaj duab xis EVA qhov qis refractive index txo qhov kev cuam tshuam ntawm lub teeb, ua kom zoo dua qhov kev hloov pauv ntawm lub zog hnub ci mus rau hauv hluav taws xob.
Zaj duab xis EVA kuj tseem paub txog nws cov khoom nplaum zoo heev. Nws sib txuas zoo rau ntau yam khoom siv, suav nrog iav thiab silicon, ua kom muaj lub foob ruaj khov thiab ruaj khov nyob ib puag ncig lub hnub ci. Qhov kev nplaum no yog qhov tseem ceeb rau kev tiv thaiv cov dej noo nkag mus, uas tuaj yeem ua rau xeb thiab lwm yam kev puas tsuaj. Zaj duab xis EVA tswj nws qhov kev ncaj ncees dhau sijhawm, txawm tias nyob rau hauv huab cua hnyav, qhia txog nws qhov tseem ceeb hauv kev siv tshuab hnub ci.
Lwm yam khoom tseem ceeb ntawm zaj duab xis EVA yog nws qhov kev ruaj khov thermal. Cov vaj huam sib luag hnub ci feem ntau raug rau qhov kub siab, thiab cov ntaub ntawv siv hauv lawv txoj kev tsim kho yuav tsum muaj peev xwm tiv taus cov xwm txheej no yam tsis muaj kev cuam tshuam rau kev ua tau zoo. Zaj duab xis EVA qhov kev tiv thaiv cua sov zoo heev ua kom ntseeg tau tias cov hlwb photovoltaic encapsulated tseem tiv thaiv thiab ua haujlwm zoo, txawm tias nyob rau hauv huab cua kub tshaj plaws. Cov khoom no yog qhov tshwj xeeb tshaj yog rau kev teeb tsa hnub ci hauv thaj chaw uas muaj hluav taws xob hnub ci siab thiab muaj peev xwm ua rau kub siab.
Ntxiv rau nws cov khoom tiv thaiv, zaj duab xis EVA ua kom zoo nkauj dua rau cov vaj huam sib luag hnub ci. Cov zaj duab xis pob tshab ua rau cov vaj huam sib luag hnub ci zoo nkauj thiab niaj hnub, ua rau lawv nyiam dua rau ob lub tsev thiab cov lag luam. Raws li qhov xav tau lub zog hnub ci txuas ntxiv mus, qhov tshwm sim ntawm cov thev naus laus zis hnub ci tau dhau los ua qhov tseem ceeb hauv kev txhawb nqa nws txoj kev saws txais.
Raws li kev lag luam hnub ci txuas ntxiv tsim kho tshiab, zaj duab xis EVA tseem ceeb heev. Cov kws tshawb fawb tab tom tshawb nrhiav cov qauv tshiab thiab kev txhim kho kom txhim kho nws cov kev ua tau zoo, xws li kev txhim kho UV tiv thaiv thiab txo nws cov kev cuam tshuam rau ib puag ncig. Cov kev nce qib no yuav ua kom ntseeg tau tias zaj duab xis EVA txuas ntxiv ua tau raws li qhov xav tau ntawm kev siv tshuab hnub ci thiab pab txhawb rau kev hloov pauv thoob ntiaj teb mus rau lub zog ruaj khov.
Hauv kev xaus,EVA zaj duab xisyog lub hauv paus tseem ceeb ntawm kev siv tshuab hnub ci. Nws cov khoom tiv thaiv zoo heev, pom kev zoo, nplaum, thiab cua sov ua rau nws yog ib qho tseem ceeb hauv kev tsim cov hnub ci zoo thiab ruaj khov. Thaum lub ntiaj teb hloov mus rau cov kev daws teeb meem zog rov ua dua tshiab, qhov tseem ceeb ntawm zaj duab xis EVA hauv kev txhim kho thev naus laus zis hnub ci tsis tuaj yeem hais ntau dhau. Nws ua lub luag haujlwm tseem ceeb hauv kev ua kom lub neej ntev thiab kev ua haujlwm ntawm cov hnub ci, uas yuav txuas ntxiv tsav peb txoj kev nrhiav kom huv si thiab ruaj khov dua yav tom ntej.
