I te taha o te nekehanga o te umanga rapa me te kirihou o te ao ki te mahi teitei, te hoahoa taiao me te maha o ngā mahi, kua whakatūria te Chlorinated Polyethylene (CPE) hei rauemi matua i roto i te whakarerekētanga polymer. Hei taumata matua mō te whakarerekētanga kirihou, e tu ana te CPE 135A mō tōna pumau mahi me te whai hua utu, e mahi ana hei tāpiringa tino nui mō te whakarei ake i ngā hua PVC pakari, me te tipu tonu o te mākete me te whānuitanga o ngā tono i roto i ngā rauemi hanga, ngā paipa, ngā panera me ētahi atu rāngai matua.
Ko te CPE 135A he elastomer polymer kua kōkōtia i hangaia mā te whakakōkō i te polyethylene kiato-teitei, he paura mā, kāore he paitini, kāore he kakara, he 35±2% te nui o te chlorine e whakahaeretia ana. Ko tōna kaha nui ko tōna hototahitanga pai ki te PVC pakari: i te wā e tukatukahia ana, ka hangaia he hanganga whatunga toru-ahu i roto i te matrix PVC, ka whakanui ake i te pakari o te hua i te pāmahana iti me te ātete pānga, ka whakarite i te ngāwari pai ahakoa i te -30℃ me te whakaoti i te take roa o te pakarukaru pāmahana iti i roto i te PVC tikanga. Hei tāpiri, ka tukuna e ia he ātete huarere tino pai, he ātete mura, he ātete waikura matū me te whakamarumaru hiko, ka roa ake te ora ratonga o ngā hua mutunga, ā, ka pai mō te hanga o waho, ngā paipa ahumahi, ngā wāhanga hiko me ētahi atu tono uaua.
Ko te CPE 135A, e whakamahia whānuitia ana hei whakarerekē pānga mō te PVC pakari, e whakamahia whānuitia ana i roto i ngā kōtaha tatau me ngā matapihi PVC, ngā paipa wai me te waikeri, ngā paipa waea, ngā papa pahuka, ngā pepa whakaputa me ngā hiato rakau-kirihou. I roto i te hanga kōtaha, mā te tāpiri i te 9-12 wāhanga o te CPE 135A ka whakanui ake i te kaha pānga mā te 30% ki te 50%; i roto i te hanga paipa, e 4-6 noa iho ngā wāhanga ka whakarei ake i te ātete pēhanga me te mahi pāmahana iti, ka āwhina i ngā hua ki te whakatutuki i ngā paerewa rauemi hanga o te ao. He pai te rere o te tukatuka me te horapa, ka urutau pai ki ngā tukanga whakaputa me te kōpeketanga, me te kore he ua, he wehewehe rānei, ka āwhina i ngā kaihanga ki te whakanui ake i te pai o te whakaputa me te hua o te hua.
Mai i te tau 2026, kua mau tonu te ahumahi CPE i te ia o te "pūmautanga kounga me te whakatikatika utu whaitake" e akiakihia ana e te piki haere o ngā utu rauemi mata o runga me te pikinga ake o te tono mai i ngā mākete hanganga me ngā rauemi hanga o raro. Nā tēnei kua piki ake te whakataetae o te CPE 135A paerewa-motu kounga teitei. Kua whakapai ake ngā kaihanga matua o te motu i ngā hangarau whakaputa me te arotau i ngā tukanga hei whakapai ake i te mā, te parakore me te ōritetanga o te hua, e āhei ai te CPE 135A o te motu ki te whakatutuki i ngā tono ā-rohe teitei engari ki te whiwhi kaha hoki i ngā mākete o tāwāhi tae atu ki te Tonga-mā-rāwhiti o Āhia, te Waenganui Rawhiti me Āwherika, e hangai ana ki te nekehanga whānui o te ao i raro i te Belt and Road Initiative.
Hei rauemi matua e akiaki ana i te rapa me te kirihou, kua rite te CPE 135A mō ngā tirohanga whānui ake o te mākete me te whanaketanga kounga teitei o ngā ahumahi rauemi hanga me te kirihou o te ao. Mā te whānui ake o te whakamahi i ngā hangarau whakaputa matomato me te arotau tonu i te mahi, ka whānui ake te whānuitanga o tana tono i roto i ngā rāngai pūngao hou me ngā rauemi matatau, ka werohia te ora tonu ki roto i te huringa me te whakapai ake o te ahumahi.
