Lapho ukhetha impahla yokuphahla, i-EPDM (i-ethylene propylene diene monomer) iyisinqumo esihle kakhulu. Uphahla lwe-EPDMzinikeza uhla lwezinzuzo ezizenza kube ukukhetha okudumile kwezakhiwo zokuhlala nezohwebo.
Okokuqala nokubalulekile,Uphahla lwe-EPDMzaziwa ngokuqina kwazo.Zenziwe ngenhlanganisela yerabha yokwenziwa enikeza ukumelana nesimo sezulu esihle kakhulu futhi engakwazi ukumelana nokuguquka kwezinga lokushisa okudlulele.Kungakhathaliseki ukuthi ukushisa okushisayo, amakhaza abandayo noma imvula enamandla, uphahla lwe-EPDM luhlinzeka ngokuvikela okuthembekile unyaka wonke.Ukumelana kwabo nemisebe ye-UV kuqinisekisa ukuthi uphahla ngeke luwohloke noma luqhekeke ngokuhamba kwesikhathi, okwenza kube ukutshalwa kwezimali okuhlakaniphile.
Okwesibili,Uphahla lwe-EPDMzivumelana nezimo kakhulu.Inganwebeka futhi inciphe ngaphandle kokulahlekelwa izakhiwo zayo ezibonakalayo, iyenze ibe ilungele izakhiwo ezihlala zinyakaza noma zihlale.Lokhu kuguquguquka kunciphisa kakhulu ingozi yokuvuza nokuqhekeka, ukuqinisekisa ukuthi isakhiwo sivikelekile emonakalweni wamanzi.Ukwengeza, ukuguquguquka kwayo kwenza kube lula ukuyifaka ophahleni olunezimo eziyingqayizivele nama-engeli. Uphahla lwe-EPDMfuthi iyisixazululo esingabizi kakhulu.Izindleko zayo eziphansi zokufakwa nokugcinwa kwazo ziyenza ibe inketho ekhangayo kumuntu noma ibhizinisi eliqaphela ibhajethi.Ulwelwesi lwe-EPDM alusindi futhi kulula ukuluphatha, lunciphisa isikhathi sokufakwa nezindleko zabasebenzi.Ukwengeza, zidinga ukulungiswa okuncane, ukunciphisa izindleko zesikhathi eside zokulondoloza.Uma igcinwa kahle, uphahla lwe-EPDM lungahlala iminyaka engama-40 futhi luyinani elikhulu lemali.Ukwengeza, uphahla lwe-EPDM luhambisana kakhulu nemvelo.Ngokuvamile zenziwa ngezinto ezigaywe kabusha futhi zingagaywa kabusha ekupheleni kokusebenza kwazo.I-EPDM futhi iyonga amandla njengoba okokusebenza kusiza ukulawula izinga lokushisa nokunciphisa ukusetshenziswa kwamandla ekushisiseni nasekupholiseni, ngaleyo ndlela kwehlise izikweletu zezinsiza.
Ekugcineni, uphahla lwe-EPDM lunikeza ukuguquguquka kwezicelo.Zingafakwa ngaphandle komthungo ophahleni oluyisicaba noma oluphansi futhi lufanele izakhiwo ezihlukahlukene, kuhlanganise nezindlu, izakhiwo zezohwebo kanye nezinsiza zezimboni.Ama-membrane e-EPDM angashiselwa ngokushisa noma ahlanganiswe, anikeze izinketho zokufaka ezihlukahlukene kuye ngezidingo ezithile zephrojekthi.Kafushane, ukufulela kwe-EPDM kuyindlela ehlala isikhathi eside, evumelana nezimo, engabizi kakhulu, enobungani bemvelo, futhi eguquguqukayo.Kungakhathaliseki ukuthi ikhaya lakho noma ibhizinisi lidinga uphahla olusha, ukufulela kwe-EPDM kunikeza isixazululo esithembekile nesihlala isikhathi eside esinikeza ukuvikeleka okuhle kakhulu kanye nenani elikhulu lemali.
