Hauv kev tshawb nrhiav cov kev daws teeb meem zog uas ruaj khov, lub zog hnub ci tau tshwm sim los ua lwm txoj hauv kev zoo rau cov roj fossil ib txwm muaj. Ib qho ntawm cov khoom tseem ceeb hauv kev tsim cov vaj huam sib luag hnub ci yog kev siv cov zaj duab xis ethylene vinyl acetate (EVA). Cov khoom siv tshiab no ua lub luag haujlwm tseem ceeb hauv kev ua kom cov vaj huam sib luag hnub ci ua haujlwm tau zoo thiab ruaj khov, ua rau lawv yog ib qho tseem ceeb hauv kev siv lub zog ntawm lub hnub.
Zaj duab xis hnub ci EVA yog ib yam khoom siv thermoplastic siv los qhwv cov hlwb hnub ci hauv cov photovoltaic modules. Nws lub luag haujlwm tseem ceeb yog tiv thaiv cov hlwb hnub ci los ntawm cov yam ntxwv ib puag ncig xws li dej noo, hmoov av thiab UV hluav taws xob, thaum tseem muab kev rwb thaiv hluav taws xob thiab txhim kho kev sib kis lub teeb ntawm lub module. Qhov no ua rau lub zog tso zis ntau ntxiv thiab ntev lub neej ntawm koj cov vaj huam sib luag hnub ci.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv zaj duab xis EVA hnub ci yog nws lub peev xwm los txhim kho kev ua haujlwm tag nrho ntawm lub vaj huam sib luag hnub ci. Los ntawm kev ua kom zoo rau cov hlwb hnub ci, zaj duab xis pab tswj kev ncaj ncees ntawm lub module, xyuas kom meej tias nws tuaj yeem tiv taus huab cua hnyav thiab raug tshav ntuj ntev. Qhov no ua rau cov vaj huam sib luag hnub ci tsim cov hluav taws xob txhim khu kev qha thiab ua haujlwm tau zoo dua, ua rau lawv yog cov kev daws teeb meem hluav taws xob zoo thiab ruaj khov.
Ntxiv rau nws cov khoom tiv thaiv,Cov yeeb yaj kiab hnub ci EVApab txhawb rau kev ruaj khov ntawm kev tsim hluav taws xob hnub ci. Kev siv cov khoom siv no hauv kev tsim cov vaj huam sib luag hnub ci pab txo qhov cuam tshuam rau ib puag ncig ntawm kev tsim hluav taws xob los ntawm kev siv cov khoom siv hluav taws xob rov ua dua tshiab thiab huv. Qhov no yog sib xws nrog kev siv zog thoob ntiaj teb los txo qhov kev hloov pauv huab cua thiab txo cov pa roj carbon, ua rau cov yeeb yaj kiab hnub ci EVA ua ib feem tseem ceeb ntawm kev hloov mus rau yav tom ntej ntawm lub zog ruaj khov dua.
Ntxiv mus, qhov ua tau ntev thiab ntev ntawm cov zaj duab xis EVA hnub ci pab txhawb rau qhov kev siv nyiaj ntawm cov hnub ci. Kev siv zaj duab xis EVA pab kom tau txiaj ntsig ntau tshaj plaws ntawm kev nqis peev ntawm cov haujlwm hnub ci los ntawm kev ua kom ntseeg tau tias muaj kev ntseeg siab thiab kev ua haujlwm ntev ntawm cov vaj huam sib luag hnub ci. Qhov no ua rau hnub ci yog qhov kev xaiv zoo rau kev siv hauv tsev thiab kev lag luam, thiab tsav tsheb ntxiv rau kev siv cov kev daws teeb meem zog rov ua dua tshiab.
Raws li qhov kev thov rau lub zog huv thiab rov ua dua tshiab txuas ntxiv mus, lub luag haujlwm ntawm cov yeeb yaj kiab hnub ci EVA hauv kev tsim cov vaj huam sib luag hnub ci tau dhau los ua qhov tseem ceeb dua. Nws ua rau muaj kev ua haujlwm zoo, kev ruaj khov thiab kev ruaj khov ntawm cov kab ke hnub ci, ua rau lawv yog ib qho tseem ceeb hauv kev hloov mus rau qhov chaw muaj zog ruaj khov thiab zoo rau ib puag ncig.
Hauv kev xaus,Cov yeeb yaj kiab hnub ci EVAUa lub luag haujlwm tseem ceeb hauv kev siv hluav taws xob hnub ci thiab pab txhim kho kev ua haujlwm zoo, kev ruaj khov thiab kev ruaj khov ntawm cov vaj huam sib luag hnub ci. Thaum lub ntiaj teb nrhiav kev txo nws txoj kev vam khom rau cov roj fossil thiab hloov mus rau cov chaw muaj zog huv dua, kev siv cov yeeb yaj kiab EVA hauv kev tsim cov vaj huam sib luag hnub ci yuav txuas ntxiv ua lub zog tsav tsheb hauv kev txhim kho cov kev daws teeb meem hluav taws xob ruaj khov. Los ntawm kev siv lub zog ntawm cov yeeb yaj kiab EVA hnub ci, peb tuaj yeem ua rau lub neej yav tom ntej ci ntsa iab dua, ruaj khov dua los ntawm lub zog hnub ci.
