Ko te whakapūtanga pupuhi he tikanga o tete hanga hua kauMā te pēhanga hau ka pupuhi, ka pupuhi hoki ngā kukune rewa wera kua kati i roto i te pokepokea ai. Ko te pokepokea ai tuwhera ka puta mai i te extruder ka maka te mea kirihou wera ngongo kei roto tonu i te āhua ngohengohe ki roto i te pokepokea ai. Kātahi ka whakamahia te pēhanga hau mā te hau kōpeke hei whakapēke i te mea tuwhera i te taha o te kōhao mate, kia pupuhi ai ki roto i ngā hua tuwhera kaki poto.
Ko te hangahanga pupuhi tuwhera te hangarau hanga tino nui mō te whakaputa hua kirihou tuwhera.Tata ki te katoa o ngā kirihou wera ka taea te whakamahi mō te hanga pupuhi tuwhera, pērā i te polyethylene, te PVC, te polypropylene, te polystyrene, te polyester raina, te polycarbonate, te polyamide, te cellulose acetate me te poly acid formaldehyde resin, me ētahi atu.
Mā tēnei hangarau whakakoi, kāore e taea anakewhakaputa iti rōrahingā pounamu o ētahi miririta, engari ka taea hokiwhakaputamano rita onui te rahingangā oko me ngā tāke wai rokiroki, tae atu ki ngā pōro mānu, ngā tāke wahie motuka me ngā waka hoe.
He aha ngā āhuatanga e tika ana kia whai hua mai i ngā hua pupuhi-whakakikorua?
1.Te ātete pakaru o te taiao: hei ipu, kei a ia te kaha ki te ārai i te pakaru ina pā ki te matū horoi;
2.Te ātete ki te hau (te ātete ki te uruhanga): e pā ana ki ngā āhuatanga e aukati ana i te horapa o te hāora, te hauhā waro, te hauota me te mamaoa wai ki waho.
3.Ātete ruHei tiaki i ngā taonga i roto i te ipu, me ātete ngā hua ki te pānga e kore e taea te pakaru mai i te teitei kotahi mita.
4. Hei tāpiri, kei reira te ātete ki ngā rongoā, te ātete pao, te pakari me te ātete ki te pehanga.
He aha ngā painga o te whakakoi pupuhi?
1. Ka taea e te hanganga pakitara-rua, tuwhera, te mimiti me te whakakore i te kaha pānga;
2. Hoahoa ngāwari, he mahi nui, he iti hoki te utu whakaputa;
3. Ka taea e te hangarau tukatuka te whakarerekē i te matotoru o te kukune;
4. I te wā e tukatukahia ana, ka taea te whakarerekē i te matotoru o te hua i runga i te hiahia me te kore e whakapai ake i te pokepokea ai;
5. Te hanga pēhanga iti (he iti ake te ahotea o roto o te hanga i tērā o te hanga werohanga), kia pai ake ai te pumau o te taha, te ātete ki te waikura matū me te mahi pāmahana teitei;
6. Kanorau o te huihuinga: tīwiri pato-ake, whakauru mate, whakapiri whakawhanui rivet;
7. He pokepokea māmā, he iti te utu me te poto o te huringa tukatuka;
8. Ka taea te whakaputa tere i te tauira pokepokea me te utu iti.
He tukanga hanga te whakapūtanga pupuhi e hangaia ai ngā wāhanga kirihou tuwhera: Ka whakamahia hoki hei hanga pounamu karāhe. I te nuinga o te wā, e toru ngā momo whakapūtanga pupuhi matua:te hanga pupuhi whakaputa, te hanga pupuhi werohanga, me te hanga pupuhi totoro werohanga.
Ngā Āhuatanga:
Mahi pumaume te PLC matatau.
.Ka mahi aunoa te kaweme te kaikawe.
Kaha te urume te tohatoha pai, tere hoki o te wera mā te tuku i ngā pounamu kia huri ko rātou anake, kia hurihuri hoki i roto i ngā rēri i te wā kotahi i roto i te whakamahana mua-whero.
Teitei te whakarerekētangaHei whakahohe i te whakamahana-mua ki te whakamahana i ngā āhua mā te whakarerekē i te ngongo rama me te roa o te papa whakaata i te wāhi whakamahana-mua, me te pāmahana pumau i roto i te whakamahana-mua mā te whakamahi i tētahi taputapu whakamahana aunoa.
Ngā haumaru teiteime ngā taputapu raka aunoa mō ia mahi ā-mīhini, ka huri ai ngā tukanga ki tētahi āhua haumaru mēnā ka pakaru tētahi tukanga.
Ko te tikangawhakakoi pupuhihe hanga wāhanga kirihou tuwhera, ā, he ipu hei hono i ēnei wāhanga. He maha ngā āhua me ngā rahi e wātea ana. Ko te hanga pupuhi me te hanga werohanga tētahi o ngā tikanga e whakamahia nuitia ana, ā, e whakamahia whānuitia ana me tēnei tikanga e mātou.whakaputa ngā wāhanga kirihou kounga teitei i te utu iti rawaNō reira, he huarahi pai tēnei, he iti te utu. He tikanga tawhito te hanga i ngā mea tuwhera. He maha ngā āhuatanga e pā ana ki te hanga i ngā mea tuwhera, pērā i te "momo kirihou, tere, tere, pāmahana.Ko te hau tētahi o ngā mea nui, ā, he mahi nui tana i roto i te hanga pokepoke pupuhi. Ka panaia te hau ki roto i te pokepoke hei whakawhanui, hei hoatu hoki i te āhua e hiahiatia ana. He tino māmā te tukanga hanga pokepoke pupuhi, he nui te whakamahinga, ā, he iti te utu o ngā mīhini, he iti ake te utu o te hanga pounamu kirihou mā te whakamahi i tēnei tukanga ki te whakaritea ki te hanga pokepoke werohanga. I roto i te hanga pokepoke pupuhi, kāore e hiahiatia he pokepoke hei hanga pokepoke tino tika.
Te whakahāngai pupuhi – he tukanga hanga tino motuhake e hangaia ai ngā wāhanga kirihou tuwhera, ka taea ai te hono tetahi ki tetahi.
Hemīhini pupuhi whakarewae whakamahia whānuitia ana i roto i te hanga inu arumoni. Ka hangaia e te mīhini pupuhi he pounamu kirihou e ai ki te tohutao, hei tauira, me te tohu i te kaha o te pounamu hei hanga. Kei roto i te mīhini ngā pokepoke, he kaiwhakahaere arorau ka taea te whakarite, me ngā taputapu miihini me te hiko.
