Muab cov iav npaj rau hauv lub hnab nqus tsev rau lub tshuab nqus tsev, lub tshuab nqus tsev kawm ntawv siab dua lossis sib npaug rau 700mmHg (0.092Mpa), qhov kub yog 100-110 degree (qhov ntsuas kub ntawm lub iav) , ua kom sov li 10 feeb, txias kom qis dua 60 degree, thiab tom qab ntawd tshem tawm lub tshuab nqus tsev.
Vim tias cov khoom siv ntawm EVA, muaj cov kev xav tau siab heev thaum EVA ua tiav thiab tsim. Raws li nws cov kev cai nruj heev ntawm kev pabcuam lub neej thiab kev tiv thaiv kev laus ntawm lub hnub ci, ntau lub tuam txhab tsim khoom hauv tsev tau ua tiav qhov kev vam meej hauv cov qauv tom qab txuas ntxiv mus sim thiab ua yuam kev. Feem ntau ntawm cov yeeb yaj kiab EVA hauv tsev tau mus txog qib siab thoob ntiaj teb (txhua qhov ntsuas tau ua tau raws li qhov yuav tsum tau ua, qee qhov ntsuas tau tshaj li cov khoom txawv teb chaws).
Vim tias qhov kev xav tau hnyav ntawm kev lag luam photovoltaic, cov kev xav tau rau cov khoom siv EVA kuj tseem siab heev. Kev ruaj ntseg ntawm cov cuab yeej siv, kev tswj ntawm qhov shrinkage tus nqi, thiab qhov poob ntawm nws cov qauv yog cuam tshuam tsawg li sai tau. Muaj ntau lub tuam txhab tsim cov cuab yeej ua yeeb yaj kiab hauv Suav teb, tab sis lawv txhua tus ua tsis tau raws li qhov xav tau ntau dua lossis tsawg dua. Yog li ntawd, ntau lub tuam txhab EVA tau xaiv los sib sau ua ke lossis sib sau lawv cov khoom siv. Txog xyoo 2010, muaj cov chaw tsim khoom hauv tsev ntawm tag nrho EVA zaj duab xis ntau lawm kab (Suzhou Kingwell Machinery Co., Ltd.). Tuam Tshoj txoj kev loj hlob hauv kev lag luam EVA tseem nrawm dua. Tus nqi ntawm EVA zaj duab xis yog txo, thiab tus nqi ntawm photovoltaic kev lag luam yog indirectly txo.
