Kokubili irabha ye-EPDM nerabha ye-silicone ingasetshenziselwa amashubhu anciphayo abandayo kanye namashubhu ashwabana okushisa.Uyini umehluko phakathi kwalezi zinto ezimbili?
1. Ngokwentengo: Izinto zenjoloba ze-EPDM ishibhile kunezinto zenjoloba ze-silicone.
2. Mayelana nokucubungula: Irabha ye-Silicone ingcono kune-EPDM.
3. Mayelana nokumelana nokushisa: irabha ye-silicone inokumelana nokushisa okungcono, irabha ye-EPDM inokumelana nokushisa kwe-150 ° C, futhi i-silicon rubber inokumelana nokushisa kwe-200 ° C.
4. Ukumelana nesimo sezulu: Irabha ye-ethylene-propylene imelana kangcono nesimo sezulu, futhi irabha ngokwayo ihambisana nemvelo, kodwa endaweni enomswakama, irabha ye-ethylene-propylene mancane amathuba okuthi izale amagciwane.
5. Isilinganiso sokunwetshwa kwesilinganiso sokuncipha: manje isilinganiso sokuncipha kweshubhu le-silicone yerabha ebandayo siphezulu kunaleso seshubhu le-EPDM elibandayo.
6. Umehluko ekushiseni: Uma uvutha, irabha ye-silicone izokhipha umlilo okhanyayo, cishe awukho umusi, awukho iphunga, nezinsalela ezimhlophe ngemva kokuvutha.EPDM, asikho isenzakalo esinjalo.
7. Mayelana nokudabula nokubhoboza ukumelana: I-EPDM ingcono.
8. Ezinye izici: Irabha ye-ethylene-propylene ine-ozone enhle namandla aphezulu;ubulukhuni obukhulu kanye ne-brittleness ephansi yokushisa ephansi;ijeli ye-silica inokunwebeka okuhle nokusebenza okuhle kokushisa okuphansi;i-ozone evamile, amandla aphansi!
