Ka taea te whakamahi te rapa EPDM me te rapa silicone mo te ngongo ngongo makariri me te ngongo wera.He aha te rereketanga o enei rauemi e rua?
1. Mo te utu: He iti ake nga taonga rapa EPDM i nga taonga rapa silicone.
2. Mo te tukatuka: He pai ake te rapa Silicone i te EPDM.
3. I runga i nga ahuatanga o te paanga o te pāmahana: he pai ake te whakamaarama o te rapa silicone, he 150°C te parenga o te rapa o te EPDM, he 200°C te wera o te rapa silicon.
4. Te parenga huarere: He pai ake te rapa ethylene-propylene ki te huarere, a, ko te rapa ano he pai ki te taiao, engari i roto i te taiao makuku, ka iti ake te ahua o te rapa ethylene-propylene ki te whakatipu huakita.
5. Horohanga ōwehenga whakahekenga ōwehenga: ināianei he teitei ake te ōwehenga whakaheke o te rapa silicone te ngongo ngongo makariri ki runga ake i tera o EPDM ngongo ngongo makariri.
6. Te rereketanga o te wera: I te wa e tahuna ana, ka tukuna e te rapa silicone he ahi kanapa, tata kore paowa, kahore he kakara, me te toenga ma i muri i te wera.EPDM, karekau he ahuatanga penei.
7. I runga i te haea me te wero werohanga: He pai ake te EPDM.
8. Ētahi atu āhuatanga: Ethylene-propylene rapa he ozone pai me te kaha teitei;te pakeke me te ngoikore o te wera iti;he pai te elasticity me te pai o te mahi pāmahana iti;ozone noa, iti kaha!
