Ngā whakaū PVCHe tūāpapa ēnei mō te mahi me te roa o te ora o ngā arai Venetian—ka ārai i te pirau wera i te wā e whakatōngia ana, ka ātete ki te pakaru taiao, ā, ka whakarite kia tutuki i ngā paerewa haumaru o te ao. Ko te whiriwhiri i te whakaū tino pai me whakarite i ngā whakaritenga hua (hei tauira, te whakamahinga o roto, o waho rānei, te ataahua) me te matū whakaū, me te whakataurite i te tutuki i ngā ture, te utu, me te whai huatanga o te tukatuka. Kei raro nei he aratohu hangarau hanganga hei whakatau tika.
Tīmata ki te Whakatutuki i ngā Ture: Ngā Paerewa Haumaru Kāore e Taea te Whiriwhiri
I mua i te aromatawai i te mahi, me whakarite kia rite ki ngā ture ā-rohe me ngā ture ā-tono—ngā mōrearea kore-ture pērā i te whakahokinga mai o ngā hua me ngā arai urunga ki te mākete.
• Ngā Here ā-Ao mō ngā Konganuku Taumaha:Ko ngā mea whakaū kei roto i te mata, te cadmium, me te mercury e āraia ana mō ngā taonga kaihoko pēnei i ngā arai Venetian. Ko te Ture REACH a te EU (Annex XVII) e ārai ana i te mata i roto i ngā hua PVC neke atu i te 0.1%, ko te US CPSC ia e ārai ana i te mata me te cadmium i roto i ngā wāhi tamariki (hei tauira, ngā arai mō ngā rūma tamariki). Ahakoa i roto i ngā mākete hou, ko te GB 28481 a Haina me ngā paerewa BIS a Īnia e whakahau ana kia whakakorea ngā hanganga konganuku taumaha.
• Ngā Whakaritenga Kounga Hau o Roto (IAQ):Mō ngā arai whare noho, pakihi rānei, karohia ngā mea whakau kei roto ngā phthalates, ngā matū waro mimiti rānei (VOC). Ko te kaupapa Indoor AirPLUS a te US EPA me te EcoLabel a te EU e pai ake ana ki ngā tāpiringa VOC-iti, e hanga anakonupūmā-konutea (Ca-Zn)he pai ake rānei ngā momo tine waro i ngā ranunga tuku iho o te Barium-Cadmium-Zinc (Ba-Cd-Zn).
• Te Pā ki te Kai, te Tata ki te Hauora rānei:Mena ka whakamahia ngā arai i roto i ngā kīhini, i ngā whare hauora rānei, tīpakohia ngā mea whakau e tutuki ana i ngā whakaritenga FDA 21 CFR §175.300 (US) EU 10/2011 rānei (ngā rauemi kirihou e pā ana ki te kai), pērā i ngā methyl tin mercaptides, ngā matatini Ca-Zn tino parakore rānei.
Arotake i te Hototahi Tukatuka
Ko te mahi a te pūmau whakaū e whakawhirinaki ana ki te pai o tana whakaurunga ki tō rauemi PVC me te tukanga hanga.
• Hototahi Raina Whakaputa:Mō te whakaputa tonu i ngā papa matapo, karohia ngā mea whakau e whakatupu ana i te puranga o ngā mate (hei tauira, te Ca-Zn kounga iti me ngā waikawa ngako nui rawa). Kōwhiria ngā mea whakau kua whakakotahihia (kaua ki te ranunga paura) kia rite ai te horapa, kia whakaitihia ai ngā rerekētanga matotoru o te papa.
• Te Mahi Tahi Whakahinuhinu:He maha ngā wā ka mahi tahi ngā mea whakau me ngā hinu whakahinuhinu (hei tauira, te ware pi polyethylene) hei whakapai ake i te rere.Ngā mea whakaū Ca-Znme whakamahi ngā hinu whakahinuhinu ā-roto hototahi hei ārai i te "pereti-waho" (ngā toenga i runga i ngā mata papa), ā, he pai te hono o ngā whakaū tine me ngā hinu whakahinuhinu o waho hei tukunga maeneene ake i te mate.
• Te Hanga Puranga me te Hanga Tonu:Mō ngā arai iti-papa, he arai tae ritenga, ka māmā ake te whakarerekē i te horopeta mā ngā wai whakaū (hei tauira, te Ca-Zn wai). Mō te whakaputanga nui-rahi, ka whakarite ngā papa matua whakaū totoka i te ōritetanga.
Taurite te Utu, te Oranga Tonu, me te Pūmautanga o te Mekameka Tuku
Ahakoa he mea nui te mahi, kāore e taea te wareware i ngā āhuatanga mahi pēnei i te utu me te pānga ki te taiao.
• Te Whai Hua o te Utu:Ko ngā whakaū Ca-Zn te mea pai rawa atu mō te nuinga o ngā arai o roto (20–30% te iti ake o te utu i te tine waro). He ohanga te Ba-Zn mō te whakamahinga o waho engari me karo i te whakamahi i roto i te whare nā te mea he tūponotanga paitini.
• Te Oranga Tonu me te Whakamahi Anō:Kōwhiria ngā whakaū e tautoko ana i ngā pūnaha PVC porowhita. He tino hototahi te Ca-Zn ki te hangarua ā-mīhini (he rerekē ki te mata, ki te cadmium rānei, e poke ana i te PVC hangarua). Ko te Ca-Zn e ahu mai ana i te koiora (i ahu mai i ngā rauemi whakahou) e hangai ana ki te Mahere Mahi Ōhanga Porowhita a te EU me te hiahia o ngā kaihoko mō ngā hua e pai ana ki te taiao.
• Te Pono o te Mekameka Tuku:He rerekē ngā utu o te konutea me te tine—whiriwhiria ngā whakaū maha-pūtake (hei tauira, ngā ranunga Ca-Zn) kaua ki ngā hanganga motuhake (hei tauira, te tine butyl) hei karo i ngā whakaroa whakaputa.
Whakamātautau me te Whakamana: Ngā Tirotiro Whakamutunga i mua i te Hanganga Tauine Katoa
I mua i te whakamahi i tētahi mea whakaū, me whakahaere ēnei whakamātautau hei manatoko i te mahi:
;
• Whakamātautau Pūmautanga Wera:Whakawetohia ngā papa tauira ka whakawera ki te 200°C mō te 30 meneti—tirohia mēnā kua rerekē te tae, kua pirau rānei.
• Whakamātautau Huarere:Whakamahia he rama xenon arc hei whakatauira i te 1,000 hāora o te pānga ki te UV—inehia te pupuri tae (mā te ine ine) me te hanganga.
• Whakamātautau IAQ:Tātarihia ngā tukunga VOC e ai ki te ASTM D5116 (US) me te ISO 16000 (EU) kia tutuki ai ngā paerewa o roto.
Whakamātautau Mīhini: Ka whakamātauhia te piko me te pānga o ngā papa (e ai ki te ISO 178) hei whakaū i te mahi ārai-piko.
He Anga Whakatau mō ngā Whakapūmau Arai Venetian PVC
• Whakatairangahia te Whakatutukitanga:Kaua e whakaurua ngā konganuku taumaha, ngā mea whakaū VOC-teitei rānei i te tuatahi.
• Tautuhia te Whakamahinga:I roto (Ca-Zn mō IAQ) vs. I waho (Ca-Zn + HALS rānei)Ba-Znmō te huarere).
• Ngā Hiahia Tukatuka Taurite:Kua whakaranua i mua mō te nui o te rahinga, wai mō ngā puranga ritenga.
• Whakamanahia te Mahi:Whakamātauria te pumau o te wera, te āhua o te huarere, me ngā tikanga mahi.
• Arotau i te Utu/Te Oranga Tonutanga:Ko te Ca-Zn te mea noa mō te nuinga o ngā mahi; ko te tine waro anake mō ngā arai ataahua, iti te rahinga.
Mā te whai i tēnei anga, ka whiriwhiria e koe he mea whakau e whakapakari ana i te roa o te mau o ngā matapo, e tutuki ana i ngā ture o te mākete, ā, e hangai ana ki ngā whāinga pumau—he mea nui mō te whakataetae i te mākete matapo PVC Venetian o te ao.
