Ina tangohia e tātou he pounamu hopi horoi e whakamahia whānuitia ana, ka kitea he tohu PET i raro i te pounamu, ko te tikanga he pounamu PET tēnei hua. Ko te nuinga o ngā pounamu PET e whakamahia ana i roto i te umanga horoi me te tiaki, ko te nuinga he nui te rahinga.
Whakamāramatanga Hua
He mea hanga ngā pounamu PET kiKirihou PETā, ka tukatukahia mā roto i ngā tukanga kotahi-taahiraa, e rua-taahiraa rānei hei whiwhi ipu kirihou.
Ko ngā āhuatanga o te kirihou PET he mama, he mārama, he ātete ki te pānga, ā, he ngāwari ki te pakaru.
Te tukanga hanga
1. Kia mārama ki te whakaaturanga
He hua pokepokea ai te tauira. Hei hua haurua-oti waenga mō te pokepokea ai totoro rua-axial i muri mai, kua oti te whakapūmau i te aukati o te tauira i te wā o te pokepokea ai weronga, ā, e kore tōna rahi e rerekē i te wā e whakamahanahia ana, e totorohia ana/e pupuhihia ana. Ko te rahi, te taumaha, me te matotoru o te pakitara o te tauira ngā mea hei aro nui atu tātou ina pupuhi ana i ngā pounamu.

Tikanga kotahi-taahiraa
Ko te tukanga whakaoti i te werohanga, te totoro me te pupuhi i roto i te mīhini kotahi e kiia ana ko te tikanga kotahi-taahiraa. Ko te tikanga kotahi-taahiraa ko te totoro me te pupuhi i muri i te whakamatao o te tauira i muri i te werohanga. Ko ōna painga matua ko te penapena hiko, te hua nui, te kore mahi ā-ringa me te whakaiti i te parahanga.
Tikanga e rua-taahiraa
Mā te tikanga e rua-taahiraa ka wehea te werohanga pupuhi me te totoro pupuhi, ā, ka mahia i runga i ngā mīhini e rua i ngā wā rerekē. Ka kiia hoki ko te tukanga werohanga pupuhi totoro pupuhi. Ko te taahiraa tuatahi ko te whakamahi i te mīhini werohanga pupuhi hei werohanga i te preform. Ko te taahiraa tuarua ko te whakamahana anō i te preform i te pāmahana rūma ka totoro pupuhi ki roto i te pounamu. Ko te painga o te tikanga e rua-taahiraa ko te taea te hoko i te preform mō te pupuhi. Ka taea te whakaiti i te haumitanga (tālena me ngā taputapu). He iti ake te rahinga o te preform i tō te pounamu, he watea mō te kawe me te rokiroki. Ka taea te pupuhi i te preform i hangaia i te wā kore-pānga ki roto i te pounamu i te wā tino pukumahi.

Rauemi me te hanganga
1. Rauemi PET
PET, polyethylene terephthalate, e kiia ana ko te polyester. Ko te ingoa Pākehā ko Polyethylene Terephthalate, ka puta mai i te tauhohenga polymerization (condensation) o ngā rauemi mata matū e rua, te waikawa terephthalic PTA (terephthalic acid) me te ethylene glycol EG (ethylicglycol).
2. Ngā mōhiotanga whānui mō te waha o te pounamu
Ko ngā diameter o te waha o te pounamu he Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (e rite ana ki te rahi T o te waha o te pounamu), ā, ko ngā whakatakotoranga miro ka taea te wehewehe kia: 400, 410, 415 (e rite ana ki te maha o ngā hurihanga miro). I te nuinga o te wā, ko te 400 he hurihanga miro kotahi, ko te 410 he 1.5 hurihanga miro, ā, ko te 415 he hurihanga miro teitei e rua.
3. Tinana o te pounamu
He tae totoka te nuinga o ngā pounamu PP me PE, he mārama te nuinga o ngā rauemi PETG, PET, PVC, he mārama rānei ngā tae, he āhua mārama, ā, he onge te whakamahi i ngā tae totoka. Ka taea hoki te rehu i ngā pounamu PET. He ira kōpiko kei raro o te pounamu i hangaia ki te pupuhi. He kanapa ake i raro i te māramatanga. He rārangi hononga kei raro o te pounamu i werohia ki te pupuhi.
4. Ngā taputapu tautoko
Ko ngā taputapu tautoko matua mō ngā pounamu pupuhi ko ngā mono o roto (e whakamahia whānuitia ana mō ngā rauemi PP me te PE), ngā taupoki o waho (e whakamahia whānuitia ana mō te PP, ABS me te kiriaku, he konumohe whakakikoruatia hoki, me te konumohe whakakikoruatia hoki, e whakamahia whānuitia ana mō ngā toner rehu), ngā taupoki o waho o te pane papu (e whakamahia whānuitia ana mō ngā wai reka me ngā hinu), ngā taupoki mānu, ngā taupoki hurihuri (e whakamahia whānuitia ana ngā taupoki hurihuri me ngā taupoki mānu mō ngā raina matū o ia rā e rere nui ana te rere), me ētahi atu.
Ngā tono ahumahi
E whakamahia whānuitia ana ngā pounamu PET i roto i te umanga whakapaipai, ko te nuinga i roto i te umanga horoi, tae atu ki te hopi horoi, ngā pounamu hinu kaukau, te toner, ngā pounamu tango whakapaipai, me ētahi atu, e pupuhihia ana, e hangaia ana hoki.
Ngā whakaaro mō te hoko
1. Ka taea te hanga i ngā pounamu pupuhi mai i ngā rauemi, ko te PET tētahi noa iho o aua mea, kei reira anō ngā pounamu pupuhi PE (ngāwari ake, he tae totoka ake, he hanga kotahi), ngā pounamu pupuhi PP (he pakeke ake, he tae totoka ake, he hanga kotahi), ngā pounamu pupuhi PETG (he mārama ake i te PET, engari kāore i te whakamahia whānuitia i Haina, he nui te utu, he nui te para, he hanga kotahi, he rauemi kāore e taea te hangarua), ngā pounamu pupuhi PVC (he pakeke ake, kāore i te pai ki te taiao, he iti ake te mārama i te PET, engari he kanapa ake i te PP me te PE)
2. He utu nui ngā taputapu kotahi-taahiraa, he iti te utu mō ngā taputapu e rua-taahiraa
3. Pounamu PEThe iti ake te utu o ngā pokepokea ai.
