I te mea ka nui haere te aro o te tangata ki te tiaki taiao me te whanaketanga tauwhiro, kua whānuitia te whakamahinga o ngā paipa i roto i ngā momo ahumahi me ngā mara. Heoi, he maha ngā wā ka pāngia ngā paipa e ngā taiao kino, pērā i te pāmahana teitei, te pēhanga teitei, me ngā mea waikura, ka nui te kino ki a rātou, ka nui ake ngā utu tiaki, ā, i ētahi wā, ka pāngia e ngā aituā, e ngā āhuatanga kino rānei o te taiao. Hei whakakore i ēnei wero, ka taea te pani i ngā paipa ki ngā paninga tiaki pērā i te...Ngā paninga 3LPEme ngā paninga FBE hei whakanui ake i te ātete ki te waikura, me te roa hoki.
Ko te paninga 3LPE, arā, ko te paninga polyethylene paparanga-toru, he pūnaha paninga maha-paparanga kei roto ko te paparanga turanga epoxy honohono (FBE), he paparanga piri me te paparanga polyethylene topcoat. He tino pai te ātete ki te waikura, te kaha miihini me te ātete pānga o te pūnaha paninga, ā, he whānui te whakamahinga i roto i te...ngā paipa hinu me te hau, ngā paipa wai me ētahi atu ahumahi e pāngia ana ngā paipa e ngā taiao waikura.
Ko te paninga FBE, i tētahi atu ringa, he pūnaha paninga kotahi-papanga kei roto he paninga paura epoxy whakamahana kua pania ki te mata o te paipa. He tino pai te piri o te pūnaha paninga, he ātete ki te pakū me te pānga, ā, he pai hoki te ātete matū, he pai mō te tiaki i ngā paipa i roto i ngā momo ahumahi pēnei i te hinu me te hau, te wai me te kawe waka.
E whakamahia whānuitia ana te paninga 3LPE me te paninga FBE i roto i te hangarau paipa nā ō rāua āhuatanga tiaki pai rawa atu. Heoi, he rerekē te whānuitanga o te whakamahinga i runga i te āhuatanga motuhake e tika ana kia whakahaerehia e te paipa.
I roto i ngā paipa hinu me te hau, he pai ake te paninga 3LPE nā te mea ka taea e ia te ātete i te mahi waikura o te hinu me te hau, tae atu ki te pānga me te waku o te oneone e karapoti ana. Hei tāpiri, ka taea hoki e ngā paninga 3LPE te ātete i te wetewete cathodic, arā, te wehenga o ngā paninga mai i ngā mata whakarewa nā ngā tauhohenga hiko. He mea nui rawa atu tēnei mō ngā paipa kua tiakina e te cathodically mai i te waikura.
In ngā paipa wai, ko te paninga FBE te kōwhiringa tuatahi nā te mea ka taea e ia te aukati i te hanganga o te kiriata koiora me te tipu o ngā huakita, ka taea te whakapoke i te kounga o te wai. He pai hoki te paninga FBE mō ngā paipa e kawe ana i ngā mea whakakoi, pērā i te onepu, te kirikiri, te paru rānei, nā te mea he tino ātete ki te kakahu.
I roto i te paipa kawe, ka taea te whakamahi i te paninga 3LPE, i te paninga FBE rānei, i runga i te āhuatanga motuhake o te kawe. Mena ka pāngia te paipa e te taiao waikura, pērā i te taiao moana, he pai ake te paninga 3LPE nā te mea ka ātete ki te mahi waikura a te wai moana me ngā rauropi moana. Mena ka pāngia te paipa e ngā mea whakakoi pērā i ngā kohuke, ngā konganuku rānei, he pai ake te paninga FBE nā te mea ka taea e ia te whakarato i te ātete kakahu pai ake i te paninga 3LPE.
Hei whakarāpopototanga, ka rerekē te whānuitanga o te paninga 3LPE me te paninga FBE i runga i ngā tikanga motuhake ohangarau paipaHe painga, he ngoikoretanga hoki ō ngā pūnaha paninga e rua. Me whai whakaaro whānui ki ngā āhuatanga maha i te kōwhiringa o te pūnaha paninga pērā i te āhua o te reo, te pāmahana me te pēhanga o te paipa, me te taiao e karapoti ana. I te whanaketanga tonu o te hangarau paipa, e whakapono ana mātou ka nui ake ngā pūnaha paninga auaha me te whai hua hei whakatutuki i ngā hiahia e tipu haere ana mō te tiaki me te haumaru o ngā paipa.
He wheketere ārai-waikura tā mātou e taea ai te mahi i ngā paninga 3PE, paninga epoxy me ētahi atu. Mēnā he pātai āu, whakapā mai ki a mātou.
