Zombini irabha ye-EPDM kunye nerabha ye-silicone zingasetyenziselwa iityhubhu zokuncitshiswa okubandayo kunye neetyhubhu zokuncitshiswa kobushushu. Yintoni umahluko phakathi kwezi zinto zimbini?
1. Ngokwexabiso: Izinto zerabha ze-EPDM zibiza kancinci kunezinto zerabha ze-silicone.
2. Ngokuphathelele ukucubungula: Irabha yesilicone ingcono kune-EPDM.
3. Ngokuphathelele ukumelana nobushushu: irabha ye-silicone inokumelana nobushushu okungcono, irabha ye-EPDM inokumelana nobushushu obuyi-150°C, kwaye irabha ye-silicon inokumelana nobushushu obuyi-200°C.
4. Ukumelana nemozulu: Irabha ye-ethylene-propylene ingcono ukumelana nemozulu, kwaye irabha ngokwayo inobuhlobo nokusingqongileyo, kodwa kwindawo enomswakama, irabha ye-ethylene-propylene ayinakwenzeka ukuba ivelise iintsholongwane.
5. Umlinganiselo wokwandiswa komlinganiselo wokuncipha: ngoku umlinganiselo wokuncipha kwetyhubhu yokuncitshiswa ebandayo yerabha yesilicone uphezulu kunowetyhubhu yokuncitshiswa ebandayo ye-EPDM.
6. Umahluko ekutshisweni: Xa kutsha, irabha yesilicone iya kukhupha umlilo oqaqambileyo, phantse kungabikho msi, kungabikho vumba, kunye nentsalela emhlophe emva kokutsha. EPDM, akukho nto injalo.
7. Ngokuphathelele ukumelana nokukrazuka nokubhoboza: I-EPDM ingcono.
8. Ezinye izinto: Irabha ye-ethylene-propylene ine-ozone elungileyo kunye namandla aphezulu; ubulukhuni obuphezulu kunye nokungaqini kakuhle kobushushu obuphantsi; ijeli ye-silica inokuguquguquka okuhle kunye nokusebenza kakuhle kobushushu obuphantsi; i-ozone eqhelekileyo, amandla aphantsi!
