He Kaihanga ahau nō {Haina}, ā, kei te whakapuaki atu ahau i taku raina pono o {Hua Pounamu Kirihou Mārama} mō ngā kaihoko pakihi-pākihi e hiahia ana ki te kounga, te rite tonu, me te tere. He mārama, he māmā hoki ā mātou pounamu, ā, he mea hanga mai i te PET kai-kai, he tino pai mō ngā hinu whakakī, ngā serum, ngā hinu, me ngā tirikara. He whānuitanga o ngā rahi e tukuna ana e mātou, mai i ngā pounamu tauira iti 10 ml ki ngā ipu whakakī 500 ml, me ngā kōwhiringa ātete tamariki me te taupoki hurihuri, ngā whitiki ātete-whakarerekē, me ngā kaki miro ātete- turuturu. Ka taea e au te whakarite i ngā taupoki, te tapanga, me te tā kia rite ki ngā whakaritenga o tō waitohu, me ngā wā arahi poto me te utu nui. E whai ana tā mātou whakahaere kounga i ngā paerewa o te ao, ā, ka tukuna e mātou te ao katoa mai i ngā whare putunga kei ngā wāhi rautaki. Mena kei te hoko koe i {Haina}, i hea atu rānei, kei a mātou te tiaki i a koe—te tuku tere, te tuku pumau, me ngā otinga takai tauine. Tukuna mai ki ahau te maha o ō pounamu me te mutunga o te pounamu, ā, māku e whakarite he utu i tēnei rā.
Kua puta ake ngā pounamu kirihou mārama hei whiringa pai mō ngā kaihoko o te ao e rapu ana i te mārama, te kaha me te whai hua o te utu. He mea hanga ki te PET mārama teitei me ngā tukanga werohanga/pupuhi matatau, ka eke ēnei pounamu ki runga ake i ngā momo rerekē i roto i te āhua whatu, te ātete pānga me ngā āhuatanga ārai, me te noho mama me te ngāwari ki te kawe. Mā te matotoru o te pakitara, ngā whakaoti kaki tika me te hototahi ki te whānuitanga o ngā kati me ngā pūnaha tapanga ka whakarite kia pai ake te mahi whakakī me te iti ake o ngā utu tākai katoa ki te karāhe, ki ngā kirihou iti iho rānei. Mō ngā hoko o te ao, ka tukuna e te hua he whakaritenga ngāwari, he mana kounga pakari, me te tutuki i ngā paerewa kai, whakapaipai me te rongoā o te ao. Ka taea te whakanekeneke i te whakaputanga, ngā wā arahi pono me ngā kōwhiringa e aro ana ki te taiao (ngā momo hangarua me ngā hoahoa rauemi iti) ka waiho ēnei pounamu kirihou mārama hei otinga ataahua mō ngā waitohu e whai ana ki te whakataurite i te ataahua, te mahi me te pumau. Kei te wātea ngā tauira, ngā whakaritenga hangarau me ngā tuhinga tiwhikete hei whakahaere i ngā whakataunga aromatawai me te rapu rauemi.
| Rauemi | Te Whakamahinga Noa | Māramatanga (Te Whakawhiti Mārama) | Kohu (%) | Kiato (g/cm³) | Kaha Kume (MPa) | Te Toronga i te Wā Whati (%) | Te Tere Tuku Hāora (cc·m⁻²·rā⁻¹) | Kohu Wai TR (g·m⁻²·rā⁻¹) | Te Pāmahana Whakarerekē Wera (°C) | Te āheinga ki te hangarua / Te mutunga o te oranga | Tukanga Hanga | Ngā Kōrero Mahi |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| PET mārama Mana | Ngā pounamu inu, wai, inu ngohengohe, takai wai mārama | 90–92% | <2% | 1.38 | 55–75 | 50–150 | 2–10 | 0.2–0.5 | 70–80 | He whānuitia te hangarua ā-mīhini (he whānuitia te kohikohinga) | Te whakarewa pupuhi totoro werohanga (ISBM) | He mārama rawa, he māmā, he ārai pai mō te nuinga o ngā inu kāore e pāngia e te mate. |
| Mārama rPET (PET hangarua) Tauwhiro | Ngā ipu inu e aro ana ki te taiao, ngā mea whakapaipai kore-whakahirahira | 85–90% | 3–6% | 1.38 | 50–70 | 40–120 | 3–12 | 0.25–0.6 | 65–75 | Ka taea te hangarua engari ko te kounga e whakawhirinaki ana ki te rerenga whakauru me te tukatuka | ISBM me te huri anō/te whakaranu — te mana whakahaere tae rerekē | He iti ake te māramatanga me te iti o te rerekētanga ki te PET tauhou; he nui ngā painga pumau. |
| PLA Mārama (Waikawa Polylactic) Ka taea te whakapūkara | Ngā inu poto, ngā ipu tuku kai matao, ngā pounamu mārama kotahi te whakamahinga | 88–92% | 4–6% | 1.24 | 50–70 | 3–10 | 10–30 | 0.6–1.5 | 50–60 | Ka taea te whakapara i te ahumahi (he iti noa ngā awa hangarua ā-mīhini) | Te whakahāngai werohanga, te whakahāngai pupuhi whakaputa | He tino mārama engari he iti te ātete ki te wera, he pakarukaru hoki (he iti noa te whakakī wera). |
| Tritan Mārama (Copolyester) Te Mahi Tino Pai | Ngā pounamu wai ka taea te whakamahi anō, ngā pounamu hākinakina, ngā ipu mārama pakari | 93–95% | <1.5% | ≈1.21 | 60–80 | 100–300 | 1–5 | 0.15–0.4 | 90–120 | Ka taea te hangarua ā-hangarau (kāore i te tino kitea i ngā awaawa taha-ara) | Te whakahāngai werohanga (ngā wāhanga totoka) / te whakaputanga mō ngā whakahāngai mua | He pakari, he mārama hoki; he ātete wera nui ake, ā, he roa hoki mō te whakamahi anō. |
| PET me te Papa Ārai (paninga / EVOH / SiOx) Ārai i Arotauhia | Ngā inu tairongo, ngā wai e roa ana te ora, ngā wai tairongo ki te hāora | 88–92% | 1–3% | 1.38 (+ārai angiangi) | 55–75 | 50–150 | 0.1–1 | 0.1–0.3 | 70–80 | Ko te āheinga hangarua e whakawhirinaki ana ki te hangarau ārai (paninga, tāpaetanga rānei) | Te paninga, te plasma/SiOx, te whakakotahitanga rānei me ngā paparanga ārai | Kua tino whakapaitia te ārai hau; he mea tino pai ina he mea nui te pumau o te whata, engari ka uaua pea te hangarua i te paninga. |
