Tirohanga Whānui o te Kōiri PPGI/PPGL
Ko te PPGI, PPGL rānei (he koiri maitai pania-tae, he koiri maitai kua peitahia rānei) he hua i hangaia mā te pani i tētahi, i ētahi paparanga rānei o te paninga waro ki runga i te mata o te pereti maitai i muri i te maimoatanga matū i mua i te whakamahinga pēnei i te tango hinu me te whakapūkara, kātahi ka tunua me te whakamaroke. Ko te tikanga, ko te pepa konutea wera-tuku, ko te pereti konutea konumohe wera-tuku rānei me te pereti konutea hiko-tuku hei papa.

Painga me te Whakamahinga
Ko te papa Al-Zn wera-tuku he pepa maitai Al-Zn wera-tuku (55% Al-Zn) hei papa hou kua pania, ā, ko te nui o te Al-Zn he 150g/㎡ (taha-rua). Ko te ātete waikura o te pepa whakarewa wera-tuku he 2-5 ngā wā i tērā o te pepa whakarewa wera-tuku. Ki te whakamahia tonutia, ki te whakamahia wā poto rānei i ngā pāmahana tae atu ki te 490°C, e kore e tino waikura, e puta rānei he unahi. Ko te kaha ki te whakaata i te wera me te mārama he 2 ngā wā i tērā o te maitai whakarewa wera-tuku, ā, ko te kaha whakaata he nui ake i te 0.75, he rauemi hanga pai mō te penapena pūngao. Ko te papa whakarewa hiko-tuku he pepa whakarewa hiko-tuku hei papa, ā, ko te hua i whiwhi mā te paninga peita waro me te tunu he pepa whakarewa hiko-tuku tae-pani. Nā te mea he angiangi te paparanga konutea o te pepa whakarewa hiko-tuku, ko te nui o te konutea he 20/20g/m2 te nuinga, nō reira kāore tēnei hua e pai mō te whakamahi ki te hanga pakitara, tuanui, me ētahi atu i waho. Engari nā tōna āhua ataahua me tōna mahi tukatuka tino pai, ka taea te whakamahi i te nuinga o te wā ki ngā taputapu kāinga, ki ngā oro, ki ngā taonga rino, ki ngā whakapaipai o roto, me ētahi atu, tata ki te 1.5 ngā wā.
