Ka taea te whakamahi i te rapa EPDM me te rapa silicone mō ngā ngongo whakaiti makariri me ngā ngongo whakaiti wera. He aha te rerekētanga i waenganui i ēnei rauemi e rua?
1. Mō te utu: He iti ake te utu o ngā rauemi rapa EPDM i ngā rauemi rapa silicone.
2. Mō te tukatuka: He pai ake te rapa silicone i te EPDM.
3. Mō te ātete pāmahana: he pai ake te ātete pāmahana o te rapa silicone, he 150°C te ātete pāmahana o te rapa EPDM, ā, he 200°C te ātete pāmahana o te rapa silicon.
4. Ātete ki te huarere: He pai ake te ātete o te rapa ethylene-propylene ki te huarere, ā, he pai hoki te rapa ki te taiao, engari i roto i te taiao makuku, he iti ake te tūponotanga ka puta he huakita i te rapa ethylene-propylene.
5. Ōwehenga whakawhanui ōwehenga mimiti: inaianei he teitei ake te ōwehenga mimiti o ngā ngongo mimiti matao rapa silicone i ērā o ngā ngongo mimiti matao EPDM.
6. Te rerekētanga o te mura: Ina mura, ka puta he ahi kanapa mai i te rapa silicone, tata kore he paoa, kore he haunga, ā, he toenga mā i muri i te mura. Kāore he āhuatanga pēnei i te EPDM.
7. Mō te ātete ki te haehae me te poka: He pai ake te EPDM.
8. Ētahi atu āhuatanga: He pai te ozone o te rapa ethylene-propylene, ā, he kaha teitei; he pakeke teitei, ā, he ngoikore te pakarukaru i te pāmahana iti; he pai te ngāwari o te silica gel, ā, he pai te mahi pāmahana iti; he iti te kaha o te ozone noa!
