Ngā Takirere Whakamau-Whakauru Pēhanga-Teitei
Ka taea te whakauru i te takirere pēhanga whakarewa teitei ki te nuinga o ngā tauira motuka, ā, ka tūtohu mātou i ngā takirere whakarewa mō ngā motuka me ngā waka mahi ka tere te taraiwa i ngā tere neke atu i te 130 maero ia hāora. Ka hiritia te wira e te takirere pēhanga whakarewa ki te gasket rapa, me te whakakaha i te nati pupuri.

Ko te matua takirere he mea hanga noa i te matua parahi, engari ko ētahi mākete ā-rohe e whiriwhiri ana ki te whakamahi i te matua konutea nā te mea he iti te utu o te matua konutea. I te nuinga o te wā, mō ngā takirere kounga teitei, ka tūtohu mātou kia whakamahia ngā matua kakau parahi me te parahi.
He rerekētanga kei waenganui i te rapa taiao me te rapa EPMD?
Tuatahi, ka riro mai te rapa maori i ngā tipu pēnei i ngā rākau rapa, ko te rapa EPDM ia ka hangaia mā te horihori; ka mārō, ka pakarukaru hoki ngā hua rapa EPDM i muri i te koroheketanga, ko ngā hua rapa maori ia ka ngawari, ka piri hoki i muri i te koroheketanga.
He pai ake te mahi pakeketanga wera o te rapa EPDM i tērā o te rapa tūturu; he pai ake hoki te mahi whakamarumaru me te mahi ārai-waikura o te rapa EPDM i tērā o te rapa tūturu; he pai ake te mahi ātete-wai, te mahi wai wera rawa o te rapa EPDM i te rapa tūturu, ko te mahi tino pai ko te ātete ki te mamaoa pēhanga teitei, he pai ake i te rapa fluorine; ko tētahi atu painga ko te rapa EPDM te mea nui rawa te whakakī, ka taea te whakakī ki ngā pango waro me ngā whakakī. Kāore e pā ki ngā āhuatanga maha o te hua me ērā atu mea.
Nō reira, me te tātaritanga i runga ake nei, ko te huinga rauemi e taunakihia ana e mātou mō te takirere kounga teitei koRapa EPDM + Kakau parahi + Matua parahi.
