Mā te whakaurunga o te Mahere Rima-tau Tekau mā Rua Tekau mā Rua, ka tere ake te tukanga tāone o tōku whenua i ia tau. Mō ia pikinga 1% o te tāone ka hiahiatia he 3.2 piriona mita kūpiko o te wai e whakamahia ana i roto i ngā tāone. Nō reira, e matapaetia ana ka mau tonu te tere toharite ā-tau o te putanga o ngā paipa kirihou ki te 15%. Ko te tere tipu whakakotahi tata ki te %.

Kua whanake ngā paipa kirihou o Haina hei wāhanga nui o ngā hua kirihou. Ko ngā rauemi hanga matū te tuawhā o ngā momo rauemi hanga hou e puta ake ana i ēnei rā i muri i te maitai, te rakau, me te sima. Ko ngā paipa kirihou, ngā kōtaha kirihou, ngā tatau me ngā matapihi ngā momo matua e rua o ngā rauemi hanga matū e whakamahia whānuitia ana. Mai i te tau 1994, kua whakaritea ngātahitia te kāwanatanga o Haina e te Manatū Hanga, te Manatū Ahumahi Matū o mua, te Kaunihera Ahumahi Mārama ā-Motu o mua o Haina, te Tari Rauemi Hanga ā-Motu, me te Kamupene Petrochemical o mua o Haina ki te whakarite tahi i te "Rōpū Ārahi Whakarite Rauemi Hanga Matū ā-Motu" hei whakatakoto me te whakaputa i ngā mahi e tika ana. Te whakawhanake i ngā whāinga rauemi hanga matū, ngā mahere, ngā kaupapa here, ngā paerewa, me ētahi atu. I roto noa i ngā tau torutoru, kua tere te whanaketanga o ngā paipa, ngā kōtaha, ngā tatau me ngā matapihi kirihou o Haina. Ko te kaha whakaputa o ngā paipa kirihou ā-motu i te tau 1994 he 240,000 tana, ā, ko te putanga he 150,000. I te tau 2000, ko te kaha whakaputa he 1.64 miriona tana, ā, ko te putanga he 1 miriona tana (ko te putanga o ngā paipa PVC-U he tata ki te 500,000 tana), kua eke te raina whakaputa paipa ki te neke atu i te 2,000, ā, ko te tauine whakaputa nui o ngā paipa polyvinyl chloride mārō he neke atu i te 10,000 tana. Neke atu i te 30 ngā umanga puta noa i te motu.

Ko ngā whatunga paipa tuku iho he paipa rino, he paipa rino maka, he paipa sima me he paipa uku. Ko ngā rauemi paipa tuku iho he āhuatanga o te whakapaunga nui o te pūngao me te parahanga taiao. I taua wā anō, kei te whatunga paipa hoki ēnei ngoikoretanga e whai ake nei: ① He poto te ora ratonga, ko te tikanga he 5-10 tau; ②He ngoikore te ātete matū me te ātete waikura; ③He ngoikore te mahi waipēhi; ④He nui te utu hanga, he roa te wā; ⑤He ngoikore te paipa, he ngāwari te turuturu, me ētahi atu. Mai i waenganui o te rautau 20, kua whakawhanakehia e ngā whenua o te ao, inā koa ko ngā whenua whakawhanake, ngā rauemi motuhake mō ngā paipa kirihou me te whakamahi i ngā paipa kirihou.

I roto i ngā tau tekau kua pahure ake nei, kua tere te whanaketanga o ngā paipa kirihou. Kei te piki haere te rongonui o ngā paipa kirihou mō te tiaki taiao me te haumaru i roto i te oranga o ia rā me ngā mahi ahumahi, ā, he mahi nui tā rātou, kāore e taea te whakakapi. Ina koa i roto i te umanga hanga, ehara i te mea ka taea e ngā paipa kirihou te whakakapi i te rino, te rakau, me ngā rauemi hanga tuku iho i te nui, engari he painga anō hoki o te penapena pūngao, te penapena rauemi, te tiaki taiao, te whakapai ake i te taiao noho, te whakapai ake i te mahi me te kounga o te whare, te whakaiti i te taumaha o te whare, me te whakaotinga watea. , He whānui te whakamahinga i roto i te tuku wai me te rerenga wai o te whare, te tuku wai me te rerenga wai o te tāone, ngā paipa hau me ētahi atu mara; ko te tere tipu o ngā paipa kirihou e 4 ngā wā te tere tipu toharite o ngā paipa, he nui ake i te tere tipu o te ōhanga ā-motu o ngā whenua rerekē. Ko te whakakapi i ngā paipa rino maka me ngā paipa maitai piauau ki ngā paipa kirihou matomato hoa taiao kua noho hei ia whanaketanga i roto i te rautau hou. Kua angitu te whakawhanaketanga o ngā paipa kirihou me te whakamahi whānuitia i roto i ngā whenua whakawhanake, inā koa i Uropi; Kua āhua whakaroa te whanaketanga o tōku whenua, engari i ngā tau tata nei, nā te kaha ake o te motu whānui o tōku whenua me te whakapainga o ngā paerewa oranga o te tangata, kua tere te ahunga whakamua o ngā paipa kirihou. Te whanaketanga o.

Kua tere te whanaketanga o ngā momo me ngā whakamahinga o ngā paipa kirihou i ngā tau kua taha ake nei. I tēnei wā, kua whanake ngā paipa kirihou o tōku whenua hei umanga rauemi hanga whare me te whānuitanga o ngā momo me te kaha whakaputa nui. Ko ngā momo matua o ngā paipa kirihou ko: ngā paipa UPVC,Ngā paipa CPVC, me ngā paipa PE. , paipa PAP, paipa PE-X, paipa PP-B,Paipa PP-R, paipa PB, paipa ABS,paipa hiato maitai-kirihou, paipa whakakaha muka karāhe, me ētahi atu. He whānuitia te whakamahinga i roto i ngā paipa tuku wai me ngā paipa rerenga wai mō te hanga whare, ngā paipa tuku wai tanumia o te tāone, ngā paipa rerenga wai, ngā paipa hau, ngā paipa tuku wai me te rerenga wai mō ngā rohe tuawhenua, ngā paipa whakamakuku, me te kawe wai para ahumahi me te wai matū, me ētahi atu, kia tutuki ai ngā hiahia o ngā momo mara o te ōhanga o te motu. Ngā hiahia rerekē o ngā paipa. Me whakawhanake me te whakaputa i tētahi momo paipa kirihou kia rite ki ngā āhuatanga me te whakamahinga o ngā momo paipa.
