Ko te raina hanga horoi me te kuru pounamu PET he huinga taputapu aunoa katoa e tukatuka ana i ngā pounamu PET para (pērā i ngā pounamu wai kohuke, ngā pounamu inu, me ētahi atu) mā te whakarōpū, te tango tapanga, te kuru, te horoi, te tango wai, te whakamaroke, me ngā tukanga whakarōpū hei whakaputa i ngā kongakonga PET ma. Koinei te raina hanga matua mō te hangarua kirihou PET.
Ngā Whakamahinga Matua me te Pūmanawa
• Ngā Whakamahinga Matua: Ka whakaputa i ngā maramara PET tino parakore, ka taea te whakamahi mō ngā miro muka matū, ngā rauemi tākai, ngā rau, me ētahi atu. Ka taea te whakamahi i ngā raina kai-kai mō te hangarua mai i te pounamu ki te pounamu (me whiwhi tiwhikete FDA me ētahi atu).
• Te Kaha Noa: 500–6000 kg/h, ka taea te whakarite kia rite ki ngā whakaritenga, he pai mō ngā tipu hangarua iti ki te nui.
Te Rere o te Tukanga Matua (Ngā Wāhanga Matua)
1. Te Wetewete me te Tātari i mua i te Tātaritanga: Te wetewete, te tango ā-ringa/ā-mīhini i ngā poke (te konganuku, ngā kōhatu, ngā pounamu ehara i te PET, me ētahi atu) hei whakapai ake i te parakore o ngā rauemi mata.
2. Tango Tapanga: Ka wehea te tinana o te pounamu PET mai i ngā tapanga PP/PE e te mīhini tango tapanga; ka taea te hangarua i ngā tapanga.
3. Te kuru: Ka tapahia ngā pounamu PET e te mīhini kuru kia 10–20 mm te matotoru, me te mata e whakahaere ana i te rahi.
4. Te Horoi me te Whakarōpū: Mā te horoi matao ka wehea ngā taupoki/tapanga pounamu; mā te horoi waku ka tangohia te hinu/piripiri; mā te horoi wera (70–80℃, me te wai kawakore) ka whakahoromata, ka tango hoki i ngā paru uaua; mā te horoi ka whakakorea, ka tangohia hoki ngā toenga; mā te horoi maha-wāhanga ka whakarite kia ma.
5. Te Whakamaroke me te Whakamaroke: Mā te whakamaroke ā-pūwero me te whakamaroke hau wera ka whakaitihia te nui o te makuku o ngā kongakonga ki te ≤0.5%, ka tutuki ai ngā whakaritenga tukatuka e whai ake nei.
6. Te Tātaritanga me te Takai Pai: Mā te tātaritanga/tātaritanga kiato ka tangohia ngā kongakonga kua memeha te tae, te PVC, me ētahi atu, ā, hei whakamutunga ka tākaihia ngā kongakonga ka rongoatia.
• Ngā Whakamahinga: Ngā whare hangarua PET, ngā whare muka matū, ngā whare tākai rauemi, ngā umanga hangarua rauemi; ka taea te whakamahi i ngā maramara mō ngā muka kakahu, ngā tākai kai (kai kounga), ngā kirihou hangarau, me ētahi atu.
Ngā Whakaaro mō te Kōwhiringa
• Te Whakataurite i te Pūmanawa: Tīpakohia ngā whakatakotoranga taputapu kia rite ki te putanga e tumanakohia ana hei karo i te maumauria o te pūmanawa, te kore rānei e ranea te pūmanawa.
• Te Taumata Hua Kua Oti: Me whai tukanga me ngā rauemi kua whakatikatikaina ake te taumata kai; ka taea e te taumata ahumahi noa te whai i tētahi whirihoranga māmā ake.
• Taumata Aunoatanga: Kōwhiria he raina aunoa-haurua, aunoa-katoa rānei, i runga i ngā utu mahi me ngā āheinga whakahaere. • Te Whakapaunga Pūngao me te Tiaki Taiao: Whakaritea ngā taputapu he iti te whakapaunga pūngao me ngā āheinga hangarua wai/wera hei whakaiti i ngā utu whakahaere me te pānga ki te taiao.
