Pantchito yomanga, kugwiritsa ntchito zida zapamwamba ndizofunikira kwambiri kuti zitsimikizire kuti nyumba zomwe zikumangidwazo zimakhala zazitali komanso zolimba. Magulu okulitsa mphira a EPDM ndi zinthu zodziwika bwino zomwe zimagwiritsidwa ntchito pomanga. Malumikizidwewa amagwira ntchito yofunika kwambiri kuti azitha kusuntha, kugwedezeka komanso kukulitsa matenthedwe pamapangidwe osiyanasiyana. Kumvetsetsa ubwino waEPDM mphira kuwonjezera mafupaangathandize akatswiri omanga kupanga zosankha mwanzeru posankha zinthu zoyenera kaamba ka ntchito yawo.
Magulu owonjezera a EPDM amadziwika chifukwa cha kukana kwambiri kutentha, kuwapanga kukhala oyenera ntchito zosiyanasiyana kuphatikizapo madzi otayira amchere, mpweya woponderezedwa ndi mankhwala osiyanasiyana. Kukana kutentha kumeneku kumatsimikizira kuti mgwirizanowu ukhoza kupirira kutentha kwakukulu popanda kusokoneza kukhulupirika kwake kwapangidwe, ndikupangitsa kuti ikhale yabwino kuti igwiritsidwe ntchito m'mafakitale omwe nthawi zonse amakhala ndi kutentha kwakukulu.
Kuphatikiza apo, zolumikizira zowonjezera za EPDM zimakhala ndi nyengo yabwino kwambiri yolimbana ndi nyengo ndipo ndizoyenera ntchito yomanga panja. Kaya ali padzuwa, mvula kapena kusinthasintha kwa kutentha, mfundozi zimatha kupirira zinthu, kuonetsetsa kuti zikugwira ntchito kwa nthawi yayitali komanso zodalirika.
Ubwino wina waukulu waZowonjezera za EPDMndi kulimba kwawo kwa gasi wabwino (kupatula ma hydrocarbons). Izi zimawapangitsa kukhala oyenera kugwiritsidwa ntchito komwe chisindikizo chotetezeka chiyenera kusungidwa, monga mapaipi a gasi kapena mankhwala. Kuthekera kwa malumikizano okulitsa a EPDM popewa kutulutsa kwa gasi kumawonjezera chitetezo chowonjezera pama projekiti omanga, kupatsa omanga ndi mainjiniya mtendere wamalingaliro.
Kuphatikiza pa EPDM, NBR (rabara ya nitrile butadiene) ndi chinthu china chomwe chimagwiritsidwa ntchito polumikizira mafupa. NBR imapereka kukana kwabwino kwamafuta, mafuta, mpweya, zosungunulira ndi mafuta, zomwe zimapangitsa kukhala chisankho chosunthika pamafakitale osiyanasiyana. Ikaphatikizidwa ndi mphira wa EPDM, NBR imakulitsa magwiridwe antchito ndi kulimba kwa zolumikizira zowonjezera, kuzipanga kukhala zoyenera kugwiritsidwa ntchito m'malo omanga ovuta kwambiri.
Pamene ntchito yomanga ikupitabe patsogolo, kufunikira kwa zipangizo zapamwamba zomwe zingathe kupirira zovuta za ntchito yamakono yomanga sikunayambe kukulirakulira. Zogwirizanitsa zowonjezera mphira za EPDM zimapereka njira yothetsera mavuto omwe akukumana nawo pomanga, kuphatikizapo kutentha kwa kutentha, kutentha kwa nyengo ndi mpweya wa mpweya, zomwe ndizofunikira kwambiri kuti zitsimikizire kukhulupirika kwa nthawi yaitali.
Mwachidule, kumvetsetsa ubwino waEPDM mphira kuwonjezera mafupandizofunikira kwa akatswiri omanga omwe akufuna kupititsa patsogolo ntchito yawo yabwino komanso yolimba. Ndi kutentha kwawo kwapadera, nyengo ndi kutsekedwa kwa mpweya, EPDM zowonjezera mphira zowonjezera ndizowonjezera pa ntchito iliyonse yomanga, kupereka kudalirika ndi mtendere wamaganizo poyang'anizana ndi zovuta zachilengedwe. Posankha zida zabwino monga zolumikizira mphira za EPDM, akatswiri omanga amatha kuwonetsetsa kuti mapulojekiti awo azikhala ndi nthawi yayitali.
