Kei te kitea te ara o te polyvinyl chloride ki roto i ngā tini tono e hanga ana i ō tātou oranga o ia rā me ngā mahi ahumahi. Mai i ngā paipa e kawe ana i te wai ki ō tātou kāinga ki ngā taura e tuku hiko ana me ngā raraunga, kāore e taea te whakataurite i te urutau o te PVC. Heoi, he hapa nui tō tēnei polymer rongonui: ko te kore pumau o te wera. Ina pāngia e ngā pāmahana teitei e hiahiatia ana mō te tukatuka—pēnei i te extrusion, te werohanga pokepoke, te calendering rānei—ka tīmata te pirau o te PVC, ka tukuna he hauwai hauwai kino (HCl) me te whakararu i te hanganga o te rauemi. Koinei te wāhi e uru mai ai ngā kaiwhakaū, ā, i roto i ngā kōwhiringa maha e wātea ana, kua roa ngā kaiwhakaū mata hei poutokomanawa i roto i te umanga PVC. Kua whiwhi ngā hanganga whakaū PVC mata i tō rātou tūranga i roto i ngā tekau tau o te mahi kua whakamātauhia, ahakoa kei te aro nui haere tonu rātou i roto i te wā e piki haere ana te mōhiotanga taiao. I roto i tēnei blog, ka rukuhia e mātou ngā tono o te ao tūturu, ngā painga matua, me ngā herenga kore e taea te karo o ēnei whakaū, me te tūhura hoki i te huarahi e whakatere ana ngā kaiārahi ahumahi i te whenua e whanake ana o te whakaū PVC.
Kia mārama ai ki te tūranga owhakaū mataI roto i te tukatuka PVC, he mea nui kia mārama ki ā rātou mahi matua. I te taumata taketake, ka mahi ngā kaiwhakaū e ahu mai ana i te mata hei kaihoroi HCl whai hua. I te wa e pirau ana te PVC i raro i te wera, ka tauhohe ngā matū mata i roto i te kaiwhakaū ki te HCl kua tukuna hei hanga i ngā pūhaumāota mata pumau, kore-rewa i te wai. Ka whakakorea e tēnei tauhohenga te huringa pirau autocatalytic, ka ārai i te pakaru atu o te mekameka polymer. Ko te mea e wehewehe ana i ngā kaiwhakaū mata i ngā momo kē atu ko tō rātou kaha ki te whakarato i te pumau wera mo te wa roa, ehara i te tiaki poto noa i te wa e tukatuka ana. Nā tēnei mahi pumau ka tino whai hua rātou mō ngā tono e tika ana kia tu atu ngā hua PVC i ngā āhuatanga taiao kino mo te roa o te oranga - he maha ngā tekau tau. Hei tāpiri, he maha ngā wā ka tukuna e ngā hanganga e ahu mai ana i te mata he ranunga taurite o te tiaki wera me ngā āhuatanga hinu, e whakangawari ana i te tukatuka mā te whakaiti i te waku i waenga i ngā matūriki PVC me waenga i te polymer rewa me te mīhini tukatuka. Ka whakarei ake tēnei mahi takirua i te pai o te whakaputa, e whakarite ana i te kounga hua pumau me te iti o te wā whakaweto.
Ngā tono mahi a te mata-ārahiWhakapūmau PVChe tino pūtake ki ngā ahumahi e kore e taea te whiriwhiri i te pakari, te pono, me te whai hua o te utu. Ko tētahi o ngā rāngai tino rongonui ko te umanga hanga, kei reira ngā paipa me ngā taputapu PVC e kitea whānuitia ana. Ahakoa e whakamahia ana mō te tuku wai inu, ngā pūnaha paru, ngā rerenga wai rānei i raro i te whenua, me ātete ēnei paipa ki te waikura, ki ngā rerekētanga pāmahana, me te ahotea miihini mō ngā tekau tau. He mea nui ngā mea whakaū mata hei whakarite i tēnei roanga o te ora; ko tō rātou pumau wera mō te wā roa ka ārai i te pirau o ngā paipa ahakoa ka pāngia e te wai wera, e te rā tika rānei. Hei tauira, ko ngā paipa pēhanga PVC pakari kua whakaūtia ki ngā matū mata ka roa ake te pupuri i tō rātou hanganga hanganga me te kaha ki te kawe pēhanga i ērā e whakamahi ana i ngā mea whakaū iti ake te pakari. Nā tēnei pono te take i whakawhirinaki ai te nuinga o ngā kaupapa hanganga, inā koa i ngā rohe he uaua ngā āhuatanga āhuarangi, kingā paipa PVC kua whakapūmauhia ki te mata.
Ko tētahi atu wāhi tono nui mō te whakapūmau mata ko te umanga hiko me te hikohiko, inā koa i roto i te whakamarumaru taura me te waea. He whānuitia te whakamahinga o te PVC mō te whakamarumaru i ngā taura hiko, ngā taura whakawhitiwhiti kōrero, me ngā waea hiko nā te mea he pai rawa atu ōna āhuatanga whakamarumaru hiko, engari ka tere te pirau o ēnei āhuatanga mena kāore i te tika te whakapūmau o te rauemi. He pai rawa atu ngā whakapūmau mata i konei nā te mea he pai rawa atu ngā pūhaumāota mata i hangaia i te wā o te tukanga whakapūmau, e whakarite ana kia mau tonu ngā āhuatanga whakamarumaru o te taura i roto i te wā. Hei tāpiri, he pai ake te ātete o ēnei whakapūmau ki te huarere, he mea pai mō ngā tono taura o waho i te wā e kitea ana te pānga ki te hihi UV, te makuku, me ngā pāmahana tino kino. Mai i ngā raina hiko o runga ki ngā taura whakawhitiwhiti kōrero o raro whenua, ka whakarite te whakamarumaru PVC whakapūmau mata kia haumaru, kia pono hoki te tuku hiko.Matū TopJoyKua hangaia ngā whakatakotoranga whakaū taura e ahu mai ana i te mata hei whakatutuki i ngā paerewa mahi hiko tino pakari, me te iti o ngā rerekētanga puranga-ki-puranga nā ngā tukanga hanga matatau e whakahaerehia ana e te PLC. He mea nui tēnei ōritetanga mō ngā kaihanga taura, kāore e taea te utu i ngā rerekētanga ka whakararu i te haumaru hiko.
Ko ngā kōtaha matapihi me ngā tatau tētahi atu whakamahinga nui mō te whakapūmau PVC mata. He pai ngā kōtaha PVC pakari i roto i te hanganga nā te mea he pai te whakamahi i te pūngao, he iti te tiaki, me te ātete ki te pirau me ngā pepeke. Heoi, ka noho tonu ēnei kōtaha ki ngā āhuatanga o te rangi—te ua, te hukarere, me ngā huringa pāmahana—e hiahia ana kia tino pai te ātete ki te huarere me te pupuri i te tae. Ka whakaratohia e ngā whakapūmau mata te ātete UV e tika ana hei ārai i te ngaro me te pakarukaru, kia mau tonu ai te ataahua me te hanganga o ngā kōtaha mō te roanga o te whare. Hei tāpiri, mā ō rātou āhuatanga whakahinuhinu ka taea te whakaputa i ngā āhua kōtaha uaua me ngā ine tika, he whakaritenga matua hei whakarite i te taunga tika me te pai o te pūngao i roto i ngā whakaurunga matapihi me ngā tatau. Ahakoa kei te piki haere te rongonui o ngā momo whakapūmau hou i roto i tēnei rāngai, kei te mau tonu te tūranga o ngā kōwhiringa mata i roto i ngā mākete kei reira te utu me te mahi roa ko ngā mea matua.
Ko ngā painga o ngā pūmau PVC mata-ā-ringa kei tua atu i tā rātou mahi i roto i ngā tono motuhake; he pai hoki mō te ōhanga me te tukatuka. Ko te whai huatanga utu pea te painga nui rawa atu. He nui te ōwehenga mahi-ki-te-utu o ngā pūmau e mata-ā-ringa ana, e hiahia ana kia iti ake te horopeta i te maha o ngā pūmau rerekē kia tutuki ai te taumata tiaki kotahi. Ka whakaitihia e tēnei ngā utu rauemi mō ngā kaihanga, he mea nui i roto i ngā ahumahi e aro nui ana ki te utu pēnei i te hanga me ngā ratonga. Hei tāpiri, ko tā rātou hototahi ki te whānuitanga o ngā whakatakotoranga PVC—mai i te pakari ki te āhua pakari ki te ngāwari—ka waiho hei otinga maha-whakamahinga, ka whakakorea te hiahia mō ngā momo pūmau maha puta noa i ngā raina hua rerekē. Mā tēnei maha-whakamahinga ka māmā ake te whakahaere taonga me ngā tukanga whakaputa, ka whakaitihia anō ngā utu whakahaere.
Ko tētahi atu painga matua o te whakapūmau mata ko tōna matapihi tukatuka whānui. He maha ngā wā ka mahi ngā kaihanga PVC i roto i ngā momo pāmahana me ngā tere tukatuka, ā, ka whakaratohia e ngā whakapūmau mata he mahi ōrite puta noa i ēnei taurangi. Ka whakaitihia e ō rātou āhuatanga whakahinuhinu te waku i te wā e whakaputa ana me te whakakoi, ka ārai i te hanga o ngā mate, ā, ka whakarite kia maeneene, kia ōrite ngā mata hua. Ehara i te mea ka whakapai ake i te kounga hua anake, engari ka whakanui ake hoki i te pai o te whakaputa mā te whakaiti i te wā kore mahi mō te horoi me te tiaki mīhini. Mō ngā kaihanga e mahi ana me te PVC hangarua,ngā whakaū e ahu mai ana i te matahe tino whai hua ngā mea nei nā te mea ka taea e rātou te whakau i ngā mekameka pūmua kua pakaru ake i roto i ngā rauemi hangarua. Ka tautokohia e tēnei ngā mahi ōhanga porowhita mā te whakawhānui ake i te whakamahinga o ngā para PVC, ahakoa he mea nui kia mōhio kei te pā tonu ngā whakaaro ture ki ngā hua hangarua kei roto he mata.
Ahakoa tōna tūranga roa me ōna painga nui, he iti noa iho ngā herenga o te whakapūmau PVC mata-ara, e aro nui ana ki te hauora, ki ngā āwangawanga taiao, me ngā ture e whanake haere ana. He konganuku taumaha paitini tonu te mata e kohia ana i roto i te tinana tangata me te taiao, ka tū hei mōrearea nui ki te hauora o ngā kaimahi e mahi ana i te tukatuka PVC me ngā kaiwhakamahi mutunga mena ka mimiti te mata i roto i ngā hua i te wā roa. Nā tēnei paitini kua ara ake ngā ture tino kaha e whakahaere ana i te whakamahinga o ngā whakapūmau mata-ara i roto i ngā rohe maha. Hei tauira, ko ngā ture REACH me RoHS a te Kotahitanga o Ūropi e tino aukati ana, e aukati ana rānei i te whakamahinga o te mata i roto i ngā tono PVC maha, inā koa ko ngā mea e pā ana ki te kai, ngā taputapu hauora, me ngā hua tamariki. Kua whakamahia ngā ture rite i Amerika Te Raki, i Hapani, me ētahi atu mākete whakawhanake, e whakawhāiti ana i te whakamahinga o ngā whakapūmau mata-ara i roto i ēnei rohe.
Ko tētahi atu herenga ko te take o te tae whanariki. Ka tauhohe ngā matū mata ki ngā matū kei roto he whanariki, ka hua ake he tae kino o ngā hua PVC. Ka whakawhāitihia te whakamahinga o ngā whakaū mata i roto i ngā tono e tino hira ana te ōritetanga o te tae, i ngā wāhi rānei ka pā atu ngā hua ki ngā taiao whai whanariki—pērā i ētahi wāhi ahumahi, i ngā tono o waho rānei e tata ana ki ngā tipu hiko waro. Hei tāpiri, kāore e pai ngā whakaū mata mō ngā hua PVC mārama, nā te mea ka puta he kohu, he tae rānei, ka whakawhāitihia te whakamahinga i roto i ngā tono pēnei i te takai mārama, i ngā kiriata mārama rānei.
Ko te pānga ki te taiao o ngā mea whakapūmau mata he nui atu i ō rātou paitini. He nui ngā rauemi e whakamahia ana e te keri me te tukatuka mata, ā, he kino ki te taiao, ka whai wāhi atu ki te parahanga o te oneone me te wai. He uaua anō hoki te whakakorenga o ngā hua PVC kei roto he mata, nā te mea ka taea e te whakakorenga hē te tuku mata ki te taiao. Nā ēnei āwangawanga taiao i akiaki te whanaketanga o ngā hangarau whakapūmau rerekē, pērā i tengā kaiwhakaū konupūmā-konutea (Ca-Zn), kāore he paitini, ā, he pai ake te taiao. Ahakoa kua nui te whanaketanga o te mahi a ēnei momo kē atu, he maha tonu ngā utu nui ake, he whaiti ake rānei ngā matapihi tukatuka ki te whakataurite ki ngā whakaū e ahu mai ana i te mata, inā koa i ngā tono e hiahia ana kia pumau te pāmahana mō te wā roa.
Mō ngā kaihanga e whakatere ana i tēnei whenua uaua, he mea nui te mahi tahi me tētahi kaiwhakarato pūmau mohio. E mōhio ana ngā kamupene pēnei i a TopJoy Chemical ki ngā hiahia rua o te umanga: te pupuri i te mahi me te whai huatanga utu me te piri ki ngā ture e whanake haere ana. Ahakoa kua whakawhānuihia e TopJoy Chemical tana putea ki te whakauru i ngā pūmau Ca-Zn mahi-teitei hei whakatutuki i te hiahia e tipu haere ana mō ngā otinga hoahoa-taiao, kei te haere tonu te tuku i ngā tohu pūmau mata kounga teitei mō ngā mākete me ngā tono kei reira tonu e tutuki ana, e tika ana hoki. Kua hangaia ēnei whakatakotoranga mata-ā-ringa me te whakaaro ki te haumaru, me te whakauru i ngā āhua kirikiri kore-pūngoi, kirikiri rānei hei whakaiti i te pānga o ngā kaimahi i te wā e whakahaerea ana—he whakapainga nui ki ngā pūmau mata paura tuku iho. Hei tāpiri, ka whakarite ngā tukanga whakahaere kounga a TopJoy Chemical kia tutuki ā rātou pūmau mata-ā-ringa i ngā paerewa umanga tino kaha mō te ōritetanga me te mahi, ka āwhina i ngā kaihanga ki te karo i ngā take whakaputa utu nui me te whakarite kia tutuki i ngā ture.
Ki te titiro whakamua, tera pea ka heke haere tonu te tūranga o te whakapūmau PVC mata-ā-ringa i ngā mākete whakawhanake i te mea ka whakakaha ake ngā ture me te whakapai ake i ngā hangarau rerekē. Heoi, i roto i te maha o ngā mākete putaiao e kore e tino kaha ngā ture, ā, ko te utu te mea nui, ka noho tonu ngā whakapūmau mata-ā-ringa hei kōwhiringa whai hua mō ngā rā kei te heke mai. Mō ēnei mākete, he mahi nui tā ngā kaiwhakarato pēnei i a TopJoy Chemical ki te whakarato i ngā otinga mata-ā-ringa haumaru, kounga teitei, me te whakaako hoki i ngā kiritaki mō ngā painga o te neke ki ngā huarahi kē atu e mau tonu ana i te whanaketanga o ngā ture.
Hei whakamutunga, kua roa ngā whakapūmau mata e mahi ana i roto i te umanga PVC, e tuku ana i te pumau wera mo te wā roa, te whai hua o te utu, me te ngāwari ki te tukatuka i roto i ngā tono nui pēnei i ngā paipa hanga, ngā taura hiko, me ngā kōtaha matapihi. He nui ō rātou herenga—e aro ana ki te paitini, ngā here ture, me te pānga ki te taiao—engari kāore e whakaiti i tō rātou hiranga tonu i roto i ētahi mākete. I te neke haere o te umanga ki ngā mahi pumau ake, kei te neke te arotahi ki ngā hangarau whakapūmau rerekē, engari ka noho tonu ngā whakapūmau mata hei wāhanga nui o te whenua PVC mō ngā tau e haere ake nei. Mā te mahi tahi me tētahi kaiwhakarato pēnei i a TopJoy Chemical, ka taea e ngā kaihanga te uru atu ki ngā otinga whakapūmau tika mō ā rātou hiahia motuhake, ahakoa he whakatakotoranga mata mahi teitei mō ngā mākete e tutuki ana i ngā ture, he huarahi pai rānei mō te taiao mō ngā rohe he ture taiao tino pakari. Hei whakamutunga, ko te whāinga he whakataurite i te mahi, te utu, me te pumau—he wero e hiahia ana ki te tohungatanga, te auahatanga, me te māramatanga hohonu ki ngā hiahia o te umanga o nāianei me te heke mai.
