Nkag siab txog Solar EVA Thin Films
Hnub ci qib EVA (ethylene-vinyl acetate copolymer) zaj duab xis yog ib qho tseem ceeb hauv kev tsim vaj huam sib luag hnub ci. Nws ua raws li cov txheej txheem tiv thaiv ib puag ncig lub hnub ci, muab cov rwb thaiv tsev thiab tiv thaiv nws los ntawm ib puag ncig yam xws li ya raws, hluav taws xob ultraviolet, thiab kev ntxhov siab. Qhov zoo ntawm EVA zaj duab xis ncaj qha cuam tshuam rau kev ua haujlwm thiab lub neej ntev ntawm lub hnub ci vaj huam sib luag; yog li ntawd, xaiv hom tsim nyog yog qhov tseem ceeb heev.
High-pob tshab EVA zaj duab xis tau nyiam heev hauv kev lag luam vim lawv cov khoom siv kho qhov muag zoo tshaj. Cov yeeb yaj kiab no ua tiav lub teeb pom kev zoo tshaj plaws, uas yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm ntawm lub hnub ci. Lub siab transparency ntawm EVA zaj duab xis ua kom ntseeg tau tias ntau lub hnub ci mus txog lub hnub ci hlwb, yog li ua kom lub zog tso zis ntau ntxiv.
Yam tseem ceeb uas yuav tau xav txog
Thaum xaiv cov hnub ci EVA zaj duab xis, cov hauv qab no yuav tsum tau txiav txim siab los xyuas kom meej lawv lub sijhawm ntev thiab pom tseeb:
Transparency thiab Light Transmittance:
Lub luag haujlwm tseem ceeb ntawmHigh Transparency EVA zaj duab xisyog tso cai rau lub hnub ci dhau mus zoo. Cov yeeb yaj kiab uas muaj lub teeb xa hluav taws xob siab, feem ntau siab dua 90%, yuav tsum tau xaiv. Qhov no ua kom ntseeg tau tias lub hnub ci hlwb tau txais kev pom lub hnub ci pom kev zoo, yog li txhim kho lawv cov kev ua haujlwm.
UV Resistance:
Cov hnub ci vaj huam sib luag raug cuam tshuam rau ib puag ncig hnyav, suav nrog hluav taws xob ultraviolet. Lub hnub ci zoo EVA zaj duab xis yuav tsum muaj UV tiv thaiv zoo los tiv thaiv yellowing thiab kev ua haujlwm degradation dhau sijhawm. Cov yam ntxwv no yog qhov tseem ceeb rau kev tswj xyuas qhov tseeb thiab kev ua haujlwm ntawm lub hnub ci vaj huam sib luag thoob plaws lawv lub neej tag nrho.
Moisture barrier:
Cov txheej txheem encapsulation yuav tsum tiv thaiv lub hnub ci cell los ntawm noo noo. EVA films uas muaj dej vapor permeability tsawg yog xaiv los xyuas kom meej lub hnub ci hlwb nyob twj ywm qhuav thiab ua hauj lwm kom zoo, tiv thaiv tej yam kev puas tsuaj thiab efficiency poob.
Thermal stability:
Hnub ci vaj huam sib luag muaj qhov kub thiab txias hloov pauv. Lub hnub ci EVA zaj duab xis tau xaiv yuav tsum muaj cov thermal stability zoo, muaj peev xwm tiv taus cov kev hloov no yam tsis muaj kev cuam tshuam rau nws txoj kev ncaj ncees. Ib zaj duab xis uas tuav nws cov kev ua tau zoo tshaj qhov kub thiab txias yuav tsum tau xaiv.
Adhesion kev ua tau zoo:
Qhov adhesion ntawm EVA zaj duab xis thiab lub hnub ci cell yog qhov tseem ceeb rau kev ua haujlwm tag nrho ntawm lub hnub ci vaj huam sib luag. Nws yog ib qho tseem ceeb uas yuav tau xaiv ib zaj duab xis uas muaj zog adhesion los tiv thaiv delamination thiab ua kom lub sij hawm ntev.
Environmental Impact:
Raws li kev tsim kho kom ruaj khov tau dhau los ua qhov tseem ceeb, thov xav txog kev cuam tshuam ib puag ncig ntawm cov khoom siv hauv cov hnub ci vaj huam sib luag. Xaiv EVA cov yeeb yaj kiab uas tsim los siv cov txheej txheem thiab cov ntaub ntawv zoo ib puag ncig.
Nyob rau hauv xaus
Xaiv txoj cai hnub ci EVA zaj duab xis, tshwj xeeb tshaj yog cov pob tshab EVA daim ntawv hnub ci, yog qhov tseem ceeb rau kev ua kom lub sij hawm ntev thiab pom tseeb ntawm cov hnub ci vaj huam sib luag. Los ntawm kev xav txog yam xws li pob tshab, UV tsis kam, dej tsis kam, thermal stability, adhesion, thiab kev cuam tshuam ib puag ncig, koj tuaj yeem ua cov kev xaiv paub uas txhim kho kev ua haujlwm thiab kev ua neej nyob ntawm koj lub hnub ci. Kev nqis peev hauv cov yeeb yaj kiab zoo hnub ci EVA tsis yog tsuas yog ua kom lub zog tso tawm xwb tab sis kuj tseem txhawb nqa kev tsim lub neej yav tom ntej.
