E mōhio ana te katoa ki ngā taputapu tukatuka PVC. He aha ngā raruraru o ngā taputapu tukatuka PVC i roto i te umanga?

1. He puhoi te whanaketanga me te hangarau MBS, ā, he whānui te mākete, engari he iti noa te wāhi mākete o ngā hua o roto.

Ahakoa kua neke atu i te 20 tau te whanaketanga o te umanga MBS ā-rohe, kei te tīmatanga tonu tēnei umanga, ā, kāore he hua a tētahi kamupene e kaha ki te whakataetae ki ngā hua o tāwāhi pērā i ngā taputapu tukatuka PVC. Ko te nuinga o ngā umanga o nāianei kei te pāngia e te maha o ngā raruraru pērā i te korenga o te whiriwhiri taputapu, ngā tukanga hangahanga kore pumau, me te korenga o ngā whanaketanga hou i roto i te hangarau hangahanga. Ahakoa te nuinga o ngā umanga kāore ā rātou ake taputapu hangahanga styrene butadiene latex, ā, ka taea anake te hoko i te styrene butadiene latex kāore i te MBS mō te hanga MBS, ā, ka taea te whakaaro ki te kounga o ā rātou hua. I tēnei wā, ko te nuinga o ngā hua e whakaurua ana ki te mākete e whakawhirinaki ana ki ngā painga utu, ā, e whakamahia ana ki ngā hua PVC kāore e hiahiatia he kounga hua teitei. I roto i te mākete teitei, he iti noa te wāhi mākete, ā, kāore anō kia pā ki ngā kamupene o tāwāhi. E matapaetia ana ko te nui o te kawemai i te tau 2006 ka noho i waenga i te 50000 me te 60000 tana, neke atu i te 70% o te katoa o te tono.

2. He iti noa ngā kairangahau me ngā whare rangahau kāore i te hanga i tētahi ope kotahi mō ngā putanga pūtaiao me ngā hangarau.

Ahakoa kua maha ngā wā kua whakarārangihia a MBS hei kaupapa rangahau pūtaiao me te hangarau ā-motu, kāore anō kia tutuki i a ia ngā putanga nui. Ko te take matua he iti ake ngā kairangahau me te iti ake o te haumi ki te hangarau. I tēnei wā, he umanga rangahau tonu kei te whakahaere i ngā whakamātautau motuhake me te rapu putanga nui, engari ka taea te kī he tauira rangahau me te whanaketanga tēnei he tauira tauhou ki te whakataurite ki ngā rōpū ke me ngā tīma rangahau pūtaiao nui.

3. I tēnei wā, he tata te taumata o ngā āwhina tukatuka PVC i Haina ki ērā o ngā hua o tāwāhi, engari nā te iti o te utu o te CPE, he uaua ki te whakatairanga i a rātou. He kōwhiringa pai te haere ki te ao whānui me te whakataetae ki ngā hua o tāwāhi mō te mākete o te ao. Heoi, ko te hua kotahi o nāianei me te kore pumau ka waiho hei take nui mā ngā kaimahi o roto o te umanga ki te whakatau.
