Kupu Whakataki: Ina tangohia e tātou he pounamu hopi horoi makawe noa, ka kitea he tohu PET i raro i te pounamu, ko te tikanga he pounamu PET tēnei hua. Ko ngā pounamu PET e whakamahia ana i te nuinga o te wā i roto i te umanga horoi me te tiaki, ā, he nui te kaha. I roto i tēnei tuhinga, ka whakaatuhia te pounamu PET hei ipu kirihou.
He ipu kirihou ngā pounamu PET i hangaia mai i te PETrauemi kirihoumā te tukatuka kotahi-taahiraa, e rua-taahiraa rānei. Ko ngā āhuatanga o te kirihou PET he mama, he mārama, he ātete ki te pānga, ā, kāore e ngawari 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.
A. Hanganga kukune pounamu
B. Te whakahāngai i te kukune pounamu
2. Te whakahāngai pounamu PET
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, te totoro me te pupuhi, ā, ka mahia ēnei i runga i ngā mīhini e rua i ngā wā rerekē, e mōhiotia ana ko te tukanga totoro me te pupuhi werohanga. Ko te taahiraa tuatahi ko te whakamahi i te mīhini hanga werohanga hei werohanga i te preform. Ko te taahiraa tuarua ko te whakamahana anō i te preform i te pāmahana rūma ka totoro ka pupuhi ki roto i te pounamu. Ko te painga o te tikanga e rua-taahiraa ko 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-wā ki roto i te pounamu i te wā tino pukumahi.
3. Te tukanga whakapūtanga pounamu PET
1. Rauemi PET:
PET, polyethylene terephthalate, e kiia nei 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 te PETG, PET, PVC, he tae mārama rānei, he āhua mārama, ā, he onge te whakamahinga o ngā tae totoka. Ka taea hoki te rehu i ngā pounamu PET. He pūwāhi 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. Te Whakataurite
Ko ngā hua matua e ōrite ana 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 mea whakakikoruatia hoki, me te konumohe whakakikoruatia, e whakamahia whānuitia ana mō te toner rehu), te uhi pane papu (e whakamahia whānuitia ana mō te hinu me te hinu whakakī), 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.
Tono
He whānuitia te whakamahinga o ngā pounamu PET i roto i te umanga whakapaipai,
te nuinga i roto i te umanga horoi me te tiaki,
tae atu ki te hopi horoi makawe, ngā pounamu hinu kaukau, te toner, ngā pounamu tango whakapaipai, me ētahi atu.
kua pupuhi katoa.
Ngā whakaaro mō te hoko
1. Ko te PET tētahi o ngā rauemi e wātea ana mō ngā pounamu pupuhi. Kei reira anō ngā pounamu pupuhi PE (ngāwari ake, he tae totoka ake, he kotahi te hanga), ngā pounamu pupuhi PP (he pakeke ake, he tae totoka ake, he kotahi te hanga), 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 kotahi te hanga, 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 rua-taahiraa
3. He iti ake te utu o ngā pokepokea ai ngā pounamu PET.
