Cov nplooj ntawv hnub ci yog qhov "txheej" sab nraud rau lub hnub ci vaj huam sib luag, thawj kab ntawm kev tiv thaiv rau lub hnub ci. Lawv ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub hnub ci vaj huam sib luag los ntawm hnyav, sib txawv ib puag ncig ntawm lub vaj huam sib luag lub neej.
Txhawm rau tiv thaiv lub vaj huam sib luag rau ntau tshaj 25 xyoo, ib daim ntawv yuav tsum muaj qhov sib npaug ntawm peb qhov tseem ceeb: weatherability, mechanical zog thiab adhesion. Cov khoom no yuav tsum tau khaws cia dhau lub neej kev pabcuam ntawm lub module.
Daim ntawv hnub ci tsis zoo yuav tshwm sim kev puas tsuaj ntawm cov vaj huam sib luag, kev puas tsuaj loj ntawm lub zog thiab muaj kev nyab xeeb loj heev. Qhov cuam tshuam tuaj yeem yog qhov tseem ceeb, txij li lub npe loj thiab lub koob npe poob mus rau lub cev raug mob.
Cov ntaub ntawv hnub ci vaj huam sib luag muaj ntau hom: TPT hnub ci ntawv, TPE hnub ci ntawv, BBF hnub ci ntawv, APE hnub ci ntawv, EVA hnub ci ntawv.
TPT Solar Sheet: TPT yog polyvinyl fluoride puas zaj duab xis. Hais lus nruj me ntsis, TPT yog peb txheej txheej zaj duab xis ua los ntawm DuPont Tedlar. DuPont tau ua haujlwm tseem ceeb rau kev kawm txog cov tshuaj fluorides. Tsis tas li ntawd, Gore txoj kev tshawb fawb kuj tseem ceeb. Gore tuaj yeem hais tias yog lub tuam txhab khiav tawm ntawm DuPont. Tedlar tsuas yog tsim los ntawm DuPont.
TPE Solar Sheet: Qhov no yog ib lo lus dav dav. Nws ua los ntawm cov thermoplastic elastomer uas feem ntau muaj xws li thaiv copolymers (styrenic resins, copolyesters, polyurethanes, thiab polyamides), nrog rau kev sib xyaw thiab cov alloys ntawm thermoplastic elastomers (thermoplastic polyolefins thiab thermoplastic vulcanizates). Ntawm lawv, thaiv copolymer yog dav siv tshwj xeeb tshaj yog styrenic resins thiab hydrogenated resins.
BBF Solar Sheet: Ib qho sib xyaw ntawm EVA + PET + THV. Feem ntau, nws yog peb txheej co-extrusion. THV resin yog terpolymer los ntawm tetrafluoroethylene, hexafluoropropylene, thiab vinylidene fluoride. Nws yog qhov nyuaj tshaj plaws fluoropolymer nrog qib siab tshaj plaws ntawm qhov pom kev pom tseeb.
APE Solar Sheet: Ib txheej yog ib zaj duab xis uas siv nylon-12 los tsim nrog kev ua tau zoo thiab huab cua tsis zoo. P yog txheej nruab nrab hloov cov khoom siv polymer alloy. Piv nrog rau PET cov khaubncaws sab nraud povtseg, nws muaj qhov zoo dua hydrolysis lub sij hawm ntev, dej vapor barrier zog, thiab zoo heev hluav taws xob rwb thaiv tsev zog; E txheej yog cov khoom siv polyolefin hloov kho uas tuaj yeem sib txuas ntawm EVA encapsulant zaj duab xis nrog kev ua haujlwm siab rau ultraviolet hluav taws xob laus.
EVA Solar Sheet: Ethylene-vinyl acetate resin. Nws muaj qhov ua tau zoo, tsis muaj qhov nplaum ntawm chav tsev kub, thiab muaj zog adhesion ntawm daim ntawv thiab iav ntawm qee qhov kub.
Rau saum EVA cov ntaub ntawv hnub ci, nws xav tau tert-butyl ethyl carbonate peroxide (TBEC, 97%) los ua tus neeg sawv cev sib txuas. Qhov no yog cov kua ntshiab uas tsis muaj xim thiab nws qhov kub ntawm nws tus kheej accelerating decomposition (SADT) yog 60 degree. TBEC yog yooj yim soluble nyob rau hauv cawv, ethers, esters, thiab hydrocarbon organic solvents, insoluble nyob rau hauv dej. TBEC yuav tsum nyob deb ntawm qhov hluav taws kub, qhov chaw kub, tsis txhob sib cuag nrog cov neeg ua haujlwm txo qis, acids, alkalis, thiab cov hlau hnyav.
