I tua atu i te wai, Ko te nuinga o nga panui e whakamahia ana i roto i te whakawhiti wera pereti he otinga hiroki, he otinga taonga, he konutai waikawa, he waikawa pungatara me etahi atu matū matū, he ngawari ki te hanga i te waikura o te pereti me te pupuhi me te koroheketanga o te gasket.
Ko te pereti me te pereti nga mea matua o te whakawhiti wera pereti, Na reira he mea tino nui te kowhiringa o te pereti me te pereti.
Te kowhiringa rauemi pereti mo te whakawhiti wera pereti:
| Te wai parakore, te wai awa, te hinu kai, te hinu kohuke me etahi atu korero | kowiri tira (AISI 304, AISI 316, etc.). |
| te wai moana, te tote, te salinization me etahi atu korero | titanium me te titanium palladium(Ti, Ti-Pd) |
| Whakarihia te waikawa pungatara, wairewa wairewa tote whanariki, wairewa wai pararopi me etahi atu papanga | 20Cr, 18Ni, 6Mo (254SMO) me etahi atu koranu |
| Te teitei o te pāmahana me te kukū teitei te reo houra caustic | Ni |
| Ko te waikawa pungatara, te waikawa maota me te reo waikawa phosphoric | koranu tere (C276, d205, B20) |
Te kowhiringa rauemi mo te pereti whakawhiti wera:
Ko te nuinga o nga tangata e mohio ana ko nga peera hiri rapa he taonga e whakamahia ana, penei i te EPDM, te rapa nitrile, te rapa nitrile hydrogenated, te fluororubber me etahi atu.
| EPDM | Ko te pāmahana ratonga - 25 ~ 180 ℃. He pai mo te wai whakawera reo, mamaoa, hau ozone, hinu whakahinuhinu kore hinu, waikawa ngoikore, turanga ngoikore, ketone, waipiro, ester, etc. |
| NBR | Ko te pāmahana ratonga - 15 ~ 130 ℃. He pai mo nga momo hinu hinu kohuke penei i te reo wai, te hinu hinu marama, te hinu whakahinuhinu, te hinu kararehe me te hinu huawhenua, te wai wera, te wai tote, aha atu. |
| HNBR | Ko te pāmahana ratonga - 15 ~ 160 ℃. He pai mo te wai wera reo-nui, te hinu para, te hinu whanariki me nga pūhui whanariki-waariki, etahi hinu whakawhiti wera, R134a hou me te taiao ozone. |
| FKM | Ko te pāmahana ratonga - 15 ~ 200 ℃. He pai mo te reo wai, penei i te waikawa sulfuric concentrated, te houra caustic, te hinu whakawhiti wera, te hinu hinu waipiro, te hinu hinu waikawa, te wera wera nui, te wai maota, te phosphate, etc. |
