Neke atu i te 100 tau te whakamahinga o te arai rapa i roto i te ahumahi, ko te nuinga he mea hanga mai i te whakamomona wera (mā te tikanga tāke whakamomona) te rapa mārō me te rapa āhua-mārō hei whakapai ake i tōna ātete ki te waikura me te mahi piri. I te whanaketanga o ngā rauemi polymer, kua whakaurua haeretia ngā momo rapa hangai me ētahi atu rauemi ki roto i ngā arai rapa, kia ātete ai ki te waikawa, te kawakore, te hinu, te wera, te pānga, me te tino ngāwari.
He aha te momo rapa e whakamahia ana hei rauemi arai?
E rua ngā momo rapa matua e whakamahia whānuitia ana hei rauemi whakapuru: te rapa tūturu me te rapa hangai.
Rapa Taiao:He maha ngā momo rapa polyethylene kei roto i ngā arai rapa maori. Ko te āhua o ēnei momo rapa he iti te pakeke, he nui te manawanui, he pai te ngāwari me te kaha ki te mimiti me te ārai i ngā pānga waikura o te rauemi e pa ana ki a rātou.
HangangaRuber:He pai te ātete o ngā rapa hangai pērā i te butyl, te hypalon, te neoprene me te nitrile ki ngā hauwaiwai me ngā hinu kohuke.
He painga, he ngoikoretanga hoki ō ngā momo rapa e rua, nō reira ko te momo e whakamahia ana hei rauemi arai ka whakawhirinaki ki ngā hiahia motuhake o te tono.
I ētahi whakamahinga, he raruraru noa te pakaru me te waikura, ka arahi pea ki te pakaru o ngā taputapu, te wā kore mahi, me ngā whakatikatika utu nui. Ka taea e te arai rapa pai te whakarato i te tiaki whai hua, te whakaroa i te roa o te mahi a ngā taputapu me te whakaiti i ngā utu tiaki. He maha ngā ahumahi e hiahia ana ki ngā arai rapa pakari me te pakari hei whakahaere i ngā āhuatanga mahi uaua, ā, he mea nui te ātete ki te pakū hei whakaaro i te wā e paunatia ana ngā kōwhiringa tiaki taputapu. Ko te arai rapa e pā ana ki te whakamahinga o te rapa ātete-kakahu, ātete-waikura me te ātete-mahana teitei hei arai i roto i ngā taputapu, i ngā paipa rānei.Mā ngā āhuatanga ā-tinana, ā-matū hoki o te rapa tonu ka whakaiti i te pānga o te rauemi e haria ana e te taputapu ki tōna hanganga.
Mā te whakarerekē i ngā rauemi hanga o te ngongo me te tukanga hanga, ka taea e tātou te whakaritetengongo wai mō ngā whakaritenga motuhake me ngā āhuatanga taiao o te tono, ka whakahaerehia hoki ngā whakamātautau me ngā whakamātautau e tika ana hei whakarite kia tutuki i te ngongo wai kua whakaritea ngā hiahia o te tono, ā, kia rite hoki te mahi e hiahiatia ana. Hei kamupene e tohunga ana ki te hoahoa me te hanga ngongo rapa, e whai ana a CDSR ki te whakarato i ngā ngongo rapa kounga teitei me ngā otinga kua whakaritea ki ngā kiritaki.
