Ina whakatakotoria te pūnaha taura ki raro i te whenua, ki roto i te ara raro i te whenua, ki roto rānei i te wai e ngāwari ana ki te kohikohi wai, hei ārai i te kohu wai me te wai kei uru ki te paparanga whakamarumaru taura, me te whakarite i te roa o te mahi a te taura, me whakamahi te taura i tētahi hanganga paparanga ārai ātete-ātea, kei roto ko tētahi hipoki whakarewa me tētahi hipoki hiato whakarewa-kirihou. Ko te mata, te parahi, te konumohe me ētahi atu rauemi whakarewa e whakamahia whānuitia ana hei hipoki whakarewa mō ngā taura; ka hangaia he hipoki hiato whakarewa-kirihou o te taura e te rīpene hiato whakarewa-kirihou me te hipoki polyethylene. Ko te hipoki hiato whakarewa-kirihou, e mōhiotia ana ko te hipoki whānui, he āhua ngāwari, he ngāwari te kawe, ā, he iti ake te uruhanga wai i te kirihou, te hipoki rapa, he pai mō ngā wāhi he nui ngā whakaritenga mahi ātete-wai, engari ki te whakatauritea ki te hipoki whakarewa, he iti tonu te uruhanga o te hipoki hiato whakarewa-kirihou.
I roto i ngā paerewa taura hiko reo-waenga o Ūropi pērā i te HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, ka whakamahia te rīpene konumohe pania-kirihou-kotahi-taha hei taupoki ātete wai whānui mō ngā taura hiko. Ko te paparanga whakarewa o te taha-kotahirīpene konumohe pania kirihouKei te pā tika ki te parepare ārai, ā, kei te mahi anō hoki hei parepare whakarewa. I roto i te paerewa Pākehā, me whakamātautau te kaha tango i waenga i te rīpene konumohe kua pania ki te kirihou me te uhi taura, me te whakahaere i ngā whakamātautau ātete waikura hei ine i te ātete wai radial o te taura; I te wā anō, me ine anō hoki te ātete DC o te rīpene konumohe kua pania ki te kirihou hei ine i tōna kaha ki te kawe i te iahiko poto.
1. Whakarōpūtanga o te rīpene konumohe pania kirihou
E ai ki te maha o ngā kiriata kirihou kua pania ki te rauemi papa konumohe, ka taea te wehewehe kia rua ngā momo tukanga paninga roa: he rīpene konumohe pania kirihou taha-rua me te rīpene konumohe pania kirihou taha-kotahi.
Ko te paparanga parewai me te ātete-makuku o ngā taura hiko ngaohiko reo me te iti me ngā taura whatu he mea hanga ki te rīpene konumohe pania-kirihou-rua me te polyethylene, te polyolefin me ētahi atu hipoki, he ātete-wai me te makuku. Ko te rīpene konumohe pania-kirihou-kotahi-taha te nuinga o te wā e whakamahia ana mō te parenga whakarewa o ngā taura whakawhitiwhiti kōrero.
I roto i ētahi paerewa Pākehā, haunga te whakamahinga hei hipoki ā-wai whānui, ka whakamahia hoki te rīpene konumohe pania kirihou kotahi-taha hei whakangungu whakarewa mō ngā taura ngaohiko reo, ā, he mārama ngā painga utu o te whakangungu rīpene konumohe ki te whakangungu parahi.
2. Te tukanga takai roa o te rīpene konumohe kua pania ki te kirihou
Ko te tukanga takai roa o te rīpene hiato konumohe-kirihou e pā ana ki te tukanga whakawhiti i te rīpene konumohe pania kirihou mai i te āhua papatahi taketake ki te āhua ngongo mā te raupapa whakarerekētanga pokepokea ai, me te hono i ngā taha e rua o te rīpene konumohe pania kirihou. He papatahi, he maeneene hoki ngā taha e rua o te rīpene konumohe pania kirihou, he piripono ngā taha, ā, kāore he kiri konumohe-kirihou e puta.
Ka taea te whakatinana i te tukanga o te whakarerekē i te rīpene konumohe pania kirihou mai i te āhua papatahi ki te āhua ngongo mā te whakamahi i te mate takai roa i titoa mai i te mate haona takai roa, te mate whakau raina me te mate rahi. Kei te whakaatuhia te hoahoa rere o te mate whakakoi takai roa o te rīpene konumohe pania kirihou i te pikitia e whai ake nei. Ka taea te hono i ngā taha e rua o te rīpene konumohe pania kirihou ngongo mā ngā tukanga e rua: te hono wera me te hono makariri.
(1) Te tukanga honohono wera
Ko te tukanga here wera ko te whakamahi i te paparanga kirihou o te rīpene konumohe pania kirihou hei whakangawari i te 70~90℃. I roto i te tukanga whakarerekētanga o te rīpene konumohe pania kirihou, ka whakamahanahia te paparanga kirihou i te hononga o te rīpene konumohe pania kirihou mā te whakamahi i te pū hau wera, i te mura rama rānei, ā, ka honoa ngā taha e rua o te rīpene konumohe pania kirihou mā te whakamahi i te matotoru i muri i te whakangawaritanga o te paparanga kirihou. Whakapirihia kia mau ngā taha e rua o te rīpene konumohe pania kirihou.
(2) Te tukanga here matao
E rua ngā momo o te tukanga here matao, ko te tuatahi ko te tāpiri i tētahi mate roa pumau ki waenganui o te mate caliper me te pane extruder, kia mau tonu ai te hanganga ngongo pumau o te rīpene konumohe pania kirihou i mua i te urunga ki te pane extruder, kia tata te putanga o te mate pumau ki te putanga o te matua o te mate extruder, ā, ka tomo tonu te hiato konumohe-kirihou ki te matua o te mate extruder i muri i te tango i te mate pumau. Mā te pēhanga extrusion o te rauemi hipoki e pupuri te hanganga ngongo o te rīpene konumohe pania kirihou, ā, mā te pāmahana teitei o te kirihou extruded ka whakangawari i te paparanga kirihou o te rīpene konumohe pania kirihou kia oti ai te mahi here. He pai tēnei hangarau mō te rīpene konumohe pania kirihou whakakikoruatia taha-rua, he māmā te whakahaere i ngā taputapu whakaputa, engari he uaua te tukatuka pokepokea ai, ā, he ngāwari te whakahoki i te rīpene konumohe pania kirihou.
Ko tētahi atu tukanga here matao ko te whakamahi i te here piri rewa wera, ka rewa te piri rewa wera e te mīhini whakaputa i roto i te tūranga pokepokea ai te takai roa i te taha o waho o te rīpene konumohe pania kirihou, ka pēhia ngā taha e rua o te rīpene konumohe pania kirihou mā roto i te rārangi pumau me te mate rahi i muri i te here piri rewa wera. He pai tēnei hangarau mō te rīpene konumohe pania kirihou taha-rua me te rīpene konumohe pania kirihou taha-kotahi. He ngāwari te whakahaere i ana taputapu tukatuka me te hanga pokepokea ai, engari he nui te pānga o te kounga o te piri rewa wera ki tōna pānga here.
Hei whakarite i te pono o te mahi a te pūnaha taura, me hono te parepare whakarewa ki te parepare whakamahana o te taura, nō reira me whakamahi te rīpene konumohe pania kirihou taha-kotahi hei parepare whakarewa o te taura. Hei tauira, ko te tukanga here wera kua whakahuatia i roto i tēnei pepa he pai anake mō ngā taha-rua.rīpene konumohe pania kirihou, ko te tukanga here matao mā te whakamahi i te piripiri rewa wera he pai ake mō te rīpene konumohe pania kirihou taha-kotahi.
