Ko ngā tāpaurin PVC (Polyvinyl Chloride) me PE (Polyethylene) he momo uhi ātete wai e whakamahia whānuitia ana i roto i ngā ahumahi maha. Anei te whakataurite i ō rāua āhuatanga me ā rāua whakamahinga:
1. Tāpaurin PVC
- Rauemi: He mea hanga ki te polyvinyl chloride, he maha ngā wā ka whakapakaritia ki te polyester, ki te mata rānei hei whakapakari.
- Ngā Āhuatanga:
- He tino pakari, ā, he ātete ki te haehae.
- He tino ātete ki te ātete wai me te UV (ina rongoatia).
- Kei te wātea ngā kōwhiringa ātete ahi.
- Ātete ki ngā matū, ki te harore, me te pirau.
- He kaha te mahi, ā, he roa te mau.
- Te Whai Hua o te Utu:He nui ake te utu tīmatanga o te PVC engari ka roa ake tōna uara i te roanga o te wā.
- Pānga ki te Taiao: Me tino motuhake te whakakorenga o te PVC nā te mea he nui te haukini kei roto.
- Ngā tono:
- Ngā taupoki taraka, ngā whare whakaruruhau ahumahi, ngā tēneti.
- Ngā taupoki moana (ngā tāpare poti).
- Ngā haki pānuitanga (nā te mea he ngāwari te tā).
- Te hanga me te ahuwhenua (tiakitanga taumaha).
2. Tāpaurini PE
- Rauemi: He mea hanga mai i te polyethylene whatu (HDPE, LDPE rānei), he mea pania kia kore ai e ārai wai.
- Ngā Āhuatanga:
- Māmā, ngāwari hoki.
- Ārai wai engari kāore i te tino pakari pērā i te PVC.
- Kāore i te tino ātete ki te hihi UV me te huarere kino (ka tere ake te pirau).
- Te Whai Hua o te Utu：He iti ake te utu i te PVC.
- Kāore i te tino kaha ki te haehae, ki te karawarawa rānei.
-Pānga ki te Taiao: He māmā ake te hangarua i te PE.
- Ngā tono:
- Ngā uhi rangitahi (hei tauira, mō ngā taonga o waho, ngā puranga rakau).
- He tāpare puni māmā.
- Ahuwhenua (taupoki whare kati kōtuhi, tiaki hua).
- Ngā utu mō ngā hanganga, ngā huihuinga rānei mō te wā poto.
Ko tēhea hei whiriwhiri?
- He pai ake te PVC mō te whakamahinga roa, mō ngā mahi taumaha, me ngā mahi ahumahi.
- He pai te PE mō ngā hiahia rangitahi, māmā, me te iti o te tahua.
