Mō ngā kaihanga PVC, he uaua te kimi i tētahi mea whakaū e whakataurite ana i te mahi, te ngāwari o te tukatuka, me te pumau. Ko ngā hua PVC pakari pērā i ngā anga matapihi, ngā panera tatau, me ngā kōtaha hangahanga e hiahia ana kia rite te ātete ki te wera, kia maeneene te mata, me te tutuki i ngā ture taiao tino pakari—me te pupuri tonu i te pai o te whakaputanga me te kore he. Whakauruhiangā whakaū matatini konupūmā-konutea (Ca-Zn)He otinga whakarerekē-kēmu e aro ana ki ngā wero matua o te ahumahi, me te whakatuwhera hoki i ngā mea hou mō te hanga PVC kounga teitei.
Ngā Hangarau kei Muri i ngā Granules: He aha te Hiranga o te Āhua
Kāore i rite kingā paura whakaūhe paru, he uaua ki te ine, he ngāwari rānei ki te piri, he mea hanga ngā pūmau Ca-Zn kirikiri kia tino tika. Mā te rahi ōrite o te matūriki ka ngāwari te whakauru ki roto i ngā matū PVC, ka kore ai e raru te horapa koretake—he take noa tēnei mō ngā rerekētanga o te hua. Engari ko ngā painga hangarau he nui atu i te whakahaere:
• Te Pūmautanga Wera Tino Pai:He mea nui mō te tukatuka PVC mārō (hei tauira, te whakaputanga, te whakakoi werohanga), ā, ka ātete ēnei whakaū i te pirau wera i te wā e hangaia ana i te pāmahana teitei, ka ārai i te tae ke me te ngoikore o te hanganga o ngā hua whakamutunga.
• Te Rere Whakarei Ake:Ka whakaitihia te waku i waenga i ngā matūriki kapia PVC e te āhua kirikiri, ka pai ake te rere o te rewa i te wā e tukatukahia ana. Ehara i te mea ka tere ake ngā huringa whakaputa anake, engari ka maeneene ake hoki ngā mata i runga i ngā kōtaha me ngā panera—kāore he taha taratara, he koha rānei o te mata.
• Te Whakahinuhinu Whakauru:He painga matua mō ngā rauemi hanga, ko ngā āhuatanga whakahinuhinu o ngā whakapūmau ka whakangawari i te hanga, ka taea ai te hanga maeneene o ngā wāhanga PVC matatini me te kore e piri ki te mīhini.
Ngā Whakamahinga Maha: Mai i te Hanganga ki tua atu
Ko ngā pūmau Ca-Zn kirikiri te mea tino kanapa i roto i te hanga PVC pakari, ā, ka pā tika te mahi ki te roa me te ataahua o te hua. Hei tauira, ko ngā anga matapihi me ngā panera tatau e whakawhirinaki ana ki te pumau o te wera hei tu atu i ngā āhuatanga kino o te rangi i roto i te wā, ko ngā āhua hangahanga ka whai hua mai i te horapa tonu hei pupuri i te hanganga. Engari kāore e mutu i reira ō rātou whakamahinga maha—he pai hoki mō ngā paipa PVC, ngā taputapu, tae atu ki ngā whakapaipai, ka urutau ki ngā tikanga tukatuka rerekē me te kore e whakararu i te kounga.
Mō ngā kaihanga e aro ana ki ngā mākete hanga whare matomato, he wikitoria ēnei whakaū i te ture: he rerekē ki ngā momo whakakapinga kei roto i te konganuku taumaha (hei tauira, ngā whakaū mata, cadmium rānei), he hoa-taiao, kāore he paitini, ā, e tutuki ana i ngā paerewa taiao o te ao (pēnei i ngā ture a te EU REACH me te US EPA). Nā tēnei ka waiho hei whiringa matua mā ngā waitohu e whakatairanga ana i te oranga tonutanga me te kore e whakararu i te mahi.
Ngā Kaihanga Whakatau'Ngā Wāhi Mamae Matua
He rerekē ngā wero e pā ana ki ngā kaihanga PVC, ka taea te whakararu i te pai o te whakaputa me te kounga o te hua. Anei te huarahi e aro ai ngā pūmau Ca-Zn matūriki ki ngā take tino nui:
▼ Wāhi Mamae 1: Kore e Pai te Mararatanga e Ārahi Ana ki ngā Hapa
Ko ngā mea whakaū kāore i te taurite te tohatoha ka puta he wāhi wera, he tae ke, he wāhi pakarukaru hoki i roto i ngā hua PVC—ka pau te wā me te moni o ngā kaihanga ki te mahi anō. Otinga: Mā te whakatakotoranga kirikiri ka rite te whakaranu ki te kapia PVC, ahakoa i roto i ngā extruders tere-rahi. Kāore e hiahiatia ana e ngā kaihanga te haumi ki ngā taputapu whakaranu tāpiri, te whakaroa rānei i te wā tukatuka;ngā mea whakaūmarara tonu, ka tino whakaiti i ngā reiti hapa.
▼ Wāhi Mamae 2: Te iti o te whai huatanga o te tukanga nā te kore o te rere o te mahi
Ka whakaroa te hanga o ngā matū PVC piri, ka pakaru te mīhini, ā, ka kore e ōrite te rahi o te hua. Otinga: Ka whakapai ake ngā pūmau Ca-Zn matūriki i te rere o te rewa mā te whakaiti i te waku o roto. Mā tēnei ka tere ake te tere o te raina, ka poto ake te huringa, ā, ka iti ake te wā kore mahi mō te horoi mīhini—ka whakanui ake i te hua whānui tae atu ki te 15% (i runga i ngā paearu ahumahi).
▼ Wāhanga Mamae 3: Ngā Mōrearea Whakatutukitanga Taiao
Kei te piki haere te aukati o ngā whakapūmau konganuku taumaha puta noa i te ao, ka waiho ngā kaihanga kia noho ngoikore ki ngā whiu ture me te kino o te ingoa. Otinga: Me te kore o ngā konganuku taumaha kino, ka whakakorea e ngā whakapūmau Ca-Zn kirikiri ngā tūponotanga taiao. He ngāwari ki te whakauru ki ngā raina whakaputa o nāianei (kāore e hiahiatia he whakapai ake i ngā taputapu utu nui) ā, ka āwhina i ngā waitohu ki te whakatutuki i ngā whāinga pumau me te pupuri tonu i ngā ture.
▼ Wāhanga Mamae 4: Uauatanga ki te Ine Tika
He uaua te ine tika i ngā paura whakaū, ā, ka nui rawa te whakamahinga (ka piki ake ngā utu) ka iti rānei te whakamahinga (ka raru te pumau). Otinga: He ngāwari te horopeta i ngā matūriki kirikiri mā te whakamahi i ngā taputapu whāngai paerewa, kia tika ai te whakahaere i ngā taumata tāpiri (te nuinga o te 3-5 PHR). Ehara i te mea ka whakaiti noa i te para rauemi engari ka pupuri tonu i te kounga hua ōrite i muri i te puranga.
He aha ngā Whakapūmau Ca-Zn Granular te Ao o te PVC i te Ao
I tēnei mākete e kore e taea te whiriwhiri i te whai huatanga, te pumau, me te kounga, ka tutuki i ngā whakaritenga katoa ngā whakaritenga e ngā whakaū matatini konupūmā-konutea. Ka whakatauhia e rātou ngā raruraru hanga roa, ka urutau ki ngā tono PVC pakari kanorau, ā, ka hangai ki te nekehanga a te umanga ki te hanga taiao-hoa. Mō ngā kaihanga e hiahia ana ki te whakataetae tonu, ehara tēnei hangarau i te whakapai ake noa iho—he mea nui.
Ahakoa kei te hanga koe i ngā kōtaha hanga, i ngā anga matapihi, i ngā taputapu PVC rānei, ka tukuna e ngā whakaū Ca-Zn kirikiri te pono me te mahi e hiahiatia ana hei tū motuhake i roto i te mākete kiki. I te mea ka whakakaha ake ngā ture taiao, ka tipu haere te hiahia o ngā kaihoko mō ngā hua tauwhiro, ka noho tonu ēnei whakaū hei whiringa pai mō te hunga whakaaro whakamua.Ngā kaihanga PVC.
Kua pāngia koe e ngā wero ki te horapa, te whai huatanga o te tukanga, te tutuki rānei i roto i tō hanga PVC? Tukuna mai ō whakaaro ki ngā kōrero—whakapā mai rānei ki te ako me pēhea te whakarite i ngā whakaū Ca-Zn ki tō rerenga mahi!
