Kokubili irabha ye-EPDM kanye nerabha ye-silicone kungasetshenziswa kumapayipi okunciphisa abandayo kanye namapayipi okunciphisa ukushisa. Uyini umehluko phakathi kwalezi zinto ezimbili?
1. Ngokuphathelene nentengo: Izinto zerabha ze-EPDM zishibhile kunezinto zerabha ze-silicone.
2. Ngokuphathelene nokucubungula: Irabha ye-silicone ingcono kune-EPDM.
3. Ngokuphathelene nokumelana nokushisa: irabha ye-silicone inokumelana nokushisa okungcono, irabha ye-EPDM inokumelana nokushisa okungu-150°C, kanti irabha ye-silicon inokumelana nokushisa okungu-200°C.
4. Ukumelana nesimo sezulu: Irabha ye-ethylene-propylene imelana kangcono nesimo sezulu, kanti irabha ngokwayo inobungani nemvelo, kodwa endaweni enomswakama, irabha ye-ethylene-propylene cishe ayinawo amathuba okuzala amagciwane.
5. Isilinganiso sokunwetshwa kwesilinganiso sokuncibilika: manje isilinganiso sokuncibilika kwepayipi lokuncibilika elibandayo lerabha le-silicone siphakeme kunelepayipi lokuncibilika elibandayo le-EPDM.
6. Umehluko ekushiseni: Uma kushiswa, irabha ye-silicone izokhipha umlilo okhanyayo, cishe akukho nkungu, akukho phunga, kanye nezinsalela ezimhlophe ngemva kokushiswa. EPDM, ayikho into enjalo.
7. Ngokuphathelene nokumelana nokuklebhuka nokubhoboza: i-EPDM ingcono.
8. Ezinye izici: Irabha ye-ethylene-propylene ine-ozone enhle namandla aphezulu; ubulukhuni obuphezulu kanye nokungaqini kahle kwezinga lokushisa eliphansi; ijeli ye-silica inokuqina okuhle kanye nokusebenza kahle kwezinga lokushisa eliphansi; i-ozone evamile, amandla aphansi!
