Kuhu kiri EPDM: e whakapau kia pai ai te kuhu i ngā tāpapatanga pēhi

Kei te nui ake te here ki te whakatutuki i te tāpapa tūturu me te kore e rere wai i ngā tāpatoru pēhi. Ko te wāhi tēnei ka tū a ngā tāpapa e whakakaha ana i te EPDM (i te mōhiotia hoki e Dowty tāpapaku, tāpapaku rānei). Koirā ngā taputapu tāpapa motuhake e whai ana i ngā āhua pai rawa atu o ngā tāpapaku hiriwa me ngā tāpapaku parauri hei whakarato i te tāpapa e hāngai ana ki ngā hononga kiriata.

Ko ngā tāpapaku e whakakaha ana i te EPDM he hiriwa tāpapaku, he parauri tāpapaku e hono ana ki tana taha roto. Kāore ngā tāpapaku hiriwa i te whakarato i te tautoko hanganga anake engari i te āwhina hoki i te taraiwa taraiwa e ū ana ki te horapa tāpapa. Ko te nuinga o te tāpapaku ka tū tonu ahakoa ngā pēhitanga pēhi.

Ko ngā tāpapaku parauri i hangaia ki te rauemi EPDM (ethylene propylene diene monomer) ā, he kaihanga nui ia ki te whakatutuki i te mata tāpapa me te tāpapaku haumaru. Ko te EPDM e mōhiotia ana mo tana whakapae pai ki te wera, ngā kikorangi me te mātāpuna, e pai ai ki te whakamahi ki ngā tāpapaku o ngā umanga maha.

Ko ngā pōhiri taraiwa EPDM e whakamahia ana i ngā pūnaha hydraulics, ngā whakamahinga motuka, ngā hononga kōpae, me ētahi atu whakamahinga pōhiri pāpaku. Ko te nuinga o te wā he rongonui ki ngā umanga e hiahiatia ana ngā pōhiri eke tino pakari.

Ko tētahi o ngā painga nui o ngā pōhiri taraiwa EPDM ko te māmā o te whakauru. Mā te hoahoa māmā me ngā āhua iti, ka taea te whakauru tere me te haumaru ki ngā hononga kiriata, e iti ai te wā kāore i te whakamahia me te whakapumau i te pōhiri pakari.

I runga i aua, ko ngā pōhiri taraiwa EPDM he whakautu pōhiri e taea ai te penapena i te utu. Ko te roa o te ora me te manawa ki te whara e toro atu ana ki te iti ake o ngā huringa, e penapena ana i ngā utu me te whakapai ake i te whaimana o te pūnaha pōhiri.

Ko te whakamutunga, kei te tāwhai EPDM e tāwhai tōtika ana he tāwhai whai kiko hei waiho i ngā tāwhai kaha hoki hoki wai i ngā whakamahinga toto kaha. Ko te takotoranga motuhake o ngā tāwhai metā me ngā tāwhai kōhuruhuru e whakapumau ai i te mahi pai rawa atu, ā, ko te māmā o te whakauru me te utu whai hua e noho ana ko te kōwhiringa tuatahi i runga i ngā umanga katoa. Ko ngā tāwhai EPDM e tāwhai tōtika ana ko te rongoā tino pai rawa kia eke ai ki te tāwhai tōtika i ngā tikanga uaua.
