Kua whakaaro koe me pēhea te ārai kaukau PVC kanapa e tu atu ai i te mamaoa me te rā mō ngā tau maha, me te kore e pakaru, e memeha rānei? Me pēhea rānei te pupuri a te kiriata takai kai mārama i te hou o āu kai me te pupuri tonu i tōna āhua mārama? Kei roto i tētahi wāhanga nui engari e warewarehia ana te mea ngaro:Ngā whakaū PVCI roto i te ao o te hanga kiriata maramataka, ko ēnei tāpiringa ngā kaihoahoa puku e huri ana i te polyvinyl chloride noa (PVC) hei rauemi mahi teitei. Me wetewete tātou i ngā paparanga, me te tūhura i tā rātou tūranga nui i roto i te tukanga.
Ngā Kaupapa Taketake o ngā Kiriata Maramataka me ngā Ngāwari o te PVC
Ka hangaia ngā kiriata maramara mā te tuku i tētahi matū PVC wera mā roto i tētahi raupapa roera, ka whakaparaha, ka hanga hei rau angiangi, ōrite. He whānuitia te whakamahinga o tēnei tukanga hei hanga hua pēnei i ngā rauemi takai, ngā uhi ahumahi, me ngā kiriata whakapaipai nā tōna whai huatanga me tōna kaha ki te whakaputa matotoru ōrite. Heoi, he rekereke Ākirihi tō te PVC: kei roto i tōna hanganga ngota ngā ngota haurehu kāore i te pumau, e tino ngawari ai te pirau ina pāngia e te wera, te mārama, me te hāora.
I te wā e whakamahanatia ana te PVC, ka tukuna ki ngā pāmahana teitei (mai i te 160°C ki te 200°C) kia tika ai te rewa me te hanga. Ki te kore he parenga, ka tere te pirau o te rauemi, ka tukuna te waikawa hauwaiora (HCl) ka puta te tae ke, te pakarukaru, me te ngaronga o ngā āhuatanga miihini. Koinei te wāhi e whai wāhi mai ai ngā kaiwhakaū PVC hei whakaoti rapanga tino nui.
Ngā Mahi Maha o ngā Whakapūmau PVC i roto i te Hanga Kiriata Maramataka
1. Pare Wera: Te Pupuri i te Pono i te Wā Tukatuka
Ko te mahi matua a ngā whakapūmau PVC i roto i te whakamahana he tiaki i te rauemi mai i te pirau wera. Ka taea e te pāmahana teitei te whakararuraru i te PVC i te wā e pēhia ana te roera, ka puta he tauhohenga mekameka, ka hua ake ai he hononga takirua honohono ka huri te rauemi kia kōwhai, kia parauri rānei. Mā ngā whakapūmau:
Te mimiti i te waikawa hauwai:Ka tauhohe rātou ki te HCl i tukuna i te wā e pirau ana te PVC, ka ārai i a ia kei whakaoho i te pirau haere tonu. Hei tauira, ko ngā mea whakaū i ahu mai i te konganuku pērā ikonupūmā – konutea or pāriuma – konuteaKa mau ngā matūriki i ngā ngota HCl, ka whakakore i ōna pānga kino.
Te Whakakapi i ngā Ngota Haumāota Kore-Pūmau:Ko ngā wāhanga hohe o ngā mea whakau, pērā i ngā katote konganuku, ka whakakapi i ngā ngota haurehu ngoikore i roto i te mekameka PVC, ka hanga he hanganga ngota ngota pumau ake. Mā tēnei ka roa ake te roa o te oranga wera o te rauemi i te wā o te tukanga whakamahana wera nui.
2.Kaitiaki Tae: Te Pupuri i te Āhua Ataahua
I roto i ngā mahi e hira ana te mārama o te tirohanga—pērā i te takai kai, i ngā ārai mārama rānei—kāore e taea te whiriwhiri i te pumau o te tae. He mea nui ngā mea whakaū PVC hei ārai i te ngaro o te tae:
Te Mahi Ārai Mate:Ko ētahi o ngā mea whakaū, inā koa ko ērā kei roto ngā matū waro, ngā phosphite rānei, he mahi ātete-waikura. Ka kohia e rātou ngā rauropi kore utu i puta mai i te wera, i te mārama rānei, ka aukati i a rātou kei whakaeke i ngā ngota PVC, ā, ka puta te kōwhai.
Ātete UV:Mō ngā kiriata maramataka o waho, ka whakamahia ngā mea whakau me ngā āhuatanga mimiti UV hei tiaki i te rauemi mai i ngā hihi kino o te rā. He mea nui tēnei mō ngā hua pēnei i ngā uhi tāonga māra, ngā kiriata kati kōtuhi rānei, kia mau tonu ai te tae me te kaha i roto i te wā.
3.Whakarei Ake i te Mahi: Te Whakarei Ake i ngā Āhuatanga Mīhini
Me ngāwari, me pakari, me ātete hoki ki te haehae ngā kiriata kua whakamāramahia. Ka whai wāhi atu ngā mea whakaū PVC ki ēnei āhuatanga mā te:
Te whakahinuhinu i te whakarewa:Ko ētahi o ngā mea whakaū, pērā i ngā momo mea hanga ki te hopi whakarewa, he mahi anō hoki hei hinu whakahinuhinu ā-roto. Ka whakaitihia e rātou te waku i roto i te matū PVC i te wā e whakatārewatia ana, kia rere pai ai i waenga i ngā roera. Ko te hua o tēnei he kiriata ōrite ake, he pai ake te āhua o te mata, ā, he iti ake ngā hapa.
Te Whakapai Ake i te Pūmautanga mō te Wā Roa:Mā te ārai i te pirau, ka tiakina e ngā mea whakau te āhua ā-pūkaha o te kiriata puta noa i tōna roanga o te ora. Hei tauira, ko te taupoki whitiki kawe ahumahi PVC kua whakamaua ki ngā mea whakau kounga teitei ka mau tonu tōna ngāwari me tōna kaha kume ahakoa ngā tau maha o te whakamahinga nui.
4.Hoa Taiao: Te Whakatutuki i ngā Paerewa Haumaru
I te mea kei te piki haere ngā āwangawanga mō te taiao me te hauora, kua hangaia ngā whakaū PVC hou kia pai mō te taiao. Mō ngā kiriata maramataka e whakamahia ana i roto i ngā takai kai, i ngā tono hauora rānei, me:
Kaua e Paitini:Kua whakakapia ngā kōwhiringa mata tuku iho e ngā mea whakaū konganuku kore-taumaha pērā i te ranunga konupūmā-konutea. He haumaru ēnei mō te pā tika ki te kai, ā, e tutuki ana i ngā paerewa ture tino pakari (hei tauira, ngā ture haumaru kai a te FDA i te US, i te EU rānei).
Whakaitihia te Pānga ki te Taiao:Kei te tūhura ētahi kaihanga i ngā kōwhiringa whakapūmau pirau-koiora, hangarua rānei, kia taea ai te maka atu, te whakamahi anō rānei i ngā kiriata kua oti te whakarite, me te kore e kino ki te ao.
Ngā Akoranga Take i roto i ngā Taupānga Kiriata Maramataka
Tākai Kai:I huri tētahi kamupene kai nui ki ngā kiriata PVC kua whakapūmautia ki te konupūmā – te konutea – mō ā rātou takai kai. Kāore i tutuki noa i ngā whakapūmau ngā whakaritenga haumaru kai, engari i whakapai ake hoki i te kaha ki te hiri i te wera me te ātete ki te hinu me te makuku, ā, i roa ake ai te ora o ngā hua.
Te Hanganga:I roto i te umanga hanga whare, ka whakamahia ngā kiriata PVC kua whakarārangihia me ngā tāpiringa whakau UV hei kiriuhi ātete wai. Ka taea e ēnei kiriata te tu atu ki ngā āhuatanga huarere kino mō ngā tekau tau, nā ngā āhuatanga tiaki o ngā whakau, ka whakaiti i te hiahia mō te whakakapinga pinepine.
Te Anamata o ngā Whakapūmau PVC i roto i ngā Kiriata Maramataka
I te whanaketanga o te hangarau, kei te piki haere tonu te hiahia mō ngā whakaū PVC whai hua, pumau hoki i roto i te hanga kiriata maramataka. Kei te whakawhanakehia e ngā kairangahau:
Ngā Whakapūmau Maha-mahi:Ka whakakotahihia e ēnei te wera, te UV, me te parenga ārai mate i roto i te whakatakotoranga kotahi, hei whakahaere i te tukanga hanga me te whakaiti i ngā utu.
Ngā Whakapūmau i runga i te Koiora:I ahu mai i ngā rauemi whakahou, ko te whāinga o ēnei momo kiriata hoa-taiao he whakaiti i te tapuwae taiao o ngā kiriata kua whakaritea, me te kore e whakaiti i te mahi.
Hei whakamutunga, ehara i te mea he tāpiri noa iho ngā mea whakaū PVC—ko rātou te pou tuarā o te hanga kiriata maramara. Mai i te tiaki i ngā rauemi i te wā e tukatukahia ana e te wera nui ki te whakarite i te haumaru me te roa o te wā e whakamahia ana ngā hua whakamutunga, kāore e taea te whakakorekore i ō rātou pānga. I a ngā ahumahi e whai ana ki te auahatanga me te pumau, kāore e kore ka nui ake te mahi a ēnei toa ngaro ki te hanga i te heke mai o ngā kiriata maramara.
Matū TOPJOYKua roa te kamupene e whakapau kaha ana ki te rangahau, ki te whakawhanake, me te whakaputa i ngā hua whakapūmau PVC tino pai.
