EVA Zaj Duab Xis ua nrog EVA yas ua cov khoom siv tseem ceeb muaj cov yam ntxwv ntawm kev tiv thaiv thaum tshav kub kub, kev txuag thaum tshav kub kub, poob siab thiab tsis-ntxeem. Raws li kev txheeb cais, kev siv lub teb chaws EVA tseem ceeb nyob rau theem no yog ua npuas ncauj, kev nplua nuj, thiab khau khau ib leeg, uas yog cov ntawv thov siv ntau tshaj plaws, suav txog kwv yees li 34% ntawm tag nrho cov khoom EVA noj. Hauv EVA cov khoom siv ntawm cov khoom siv khau, VA pawg feem ntau yog 15% -22%. Ua ntej xyoo 2008, thawj qhov chaw thov loj ntawm EVA yas tso rau hauv Suav teb yog cov khoom ua npuas dej, thiab cov khoom noj tso rau ntau dua 60% ntawm tag nrho cov kev noj. Nyob rau hauv xyoo tas los no, raws li qhov kev thov rau lub lag luam foaming tau txav mus txog qhov saturation, qhov feem ntawm kev noj tau tsawg. Hauv 2018, qhov kev faib ua feem ntawm EVA resin noj nyob rau hauv kev lag luam ntawm cov khoom lag luam foamed poob mus txog kwv yees li 34%.
Ntawm qhov kev nqes dej hauv qab no rau VA, qhov kev thov rau EVA zaj duab xis tau loj hlob dua. Lub ntiaj teb tshiab nruab nrog kev muaj peev xwm ntawm photovoltaics tau nce los ntawm 1.7 npaug hauv 5 xyoo, thiab kev tsim hluav taws xob tshiab hauv tsev tau nce ntau dua sai sai, nrog 2.4-npaug hauv 5 xyoo. Cov xwm txheej.
EVA zaj duab xis siv rau kev ntim khoom ntim photovoltaic yuav tsum muaj VA cov ntsiab lus tshaj 28%, tam sim no feem ntau yog tsim los ntawm cov txheej txheem kettle. Nrog rau txoj kev loj hlob sai ntawm Suav kev lag luam photovoltaic lag luam, EVA lub hnub ci cell ntim zaj duab xis ua lag luam kuj tau dhau los ntawm kev loj hlob sai. Txawm li cas los xij, vim tsis muaj peev xwm ua tau raws li cov kev xav tau ntawm kev tsim cov qib ntawm cov khoom lag luam no nyob hauv Suav teb, cov kev lag luam hauv tsev yog cov chaw nyob hauv Singapore TPC, Formosa Plastics, Hanwha, South Kauslim Hunan Petrochemical thiab lwm cov tuam txhab. Xyoo 2018, Tuam Tshoj tus neeg ua yeeb yaj kiab photovoltaic suav nrog 30.8% ntawm tag nrho cov neeg xav tau. Raws li kev twv ua ntej ntawm European Solar Energy Industry Association, lub ntiaj teb tshiab photovoltaic ntsia muaj peev xwm yuav ncav cuag 621.7GW nyob rau xyoo 2018-2022, yog li qhov xav tau yav tom ntej rau photovoltaic nplaum cov yeeb yaj kiab yuav txuas ntxiv mus sai.
