Ko te rerekētanga i waenga i te whakarewatanga tuku-makariri me te whakarewatanga tuku-wera i roto i te tukatuka paipa maitai

Te Whakarewatanga o te Tuku Wera me te Tuku Matao

Ko te whakapūmau wera me te whakapūmau matao he tikanga e rua mō te paninga o te maitai ki te konutea hei ārai i te waikura, engari he rerekē rawa te tukanga, te roa, me te utu. Ko te whakapūmau wera ko te tuku i te maitai ki roto i te kaukau konutea rewa, ka hanga he paparanga konutea pakari, he mea hono matū. Ko te whakapūmau matao, he tukanga e pania ai he paninga whai konutea, he maha ngā wā mā te rehu, mā te peita rānei.

I roto i te tukatuka paipa maitai, ko te whakapūmau he tukanga matua hei whakapai ake i te ātete ki te waikura, e rua ngā tikanga matua: te whakapūmau wera-tuku (HDG) me te whakapūmau makariri (Electro-Galvanizing, EG). He rerekētanga nui i waenga i ngā mea e rua e pā ana ki ngā mātāpono tukatuka, ngā āhuatanga paninga, me ngā horopaki e tika ana. Ko te mea e whai ake nei he tātari taipitopito mai i ngā āhuatanga o ngā tikanga tukatuka, ngā mātāpono, te whakataurite mahi, me ngā mara tono:

1. Te whakataurite i ngā tikanga tukatuka me ngā mātāpono

1. Te whakapūmau wera-tō (HDG)

Tukanga tukatuka: Ka rumakina te paipa maitai ki roto i te wai konutea rewa, ā, ka tauhohe te konutea me te rino hei hanga i tētahi paparanga koranu.
Te kaupapa hanganga paninga:
Te hononga whakarewa: Ka tauhohe te konutea rewa ki te anga paipa maitai hei hanga i tētahi paparanga Fe-Zn (wāhanga Γ Fe₃Zn₁₀, wāhanga δ FeZn₇, me ētahi atu), ā, ko te paparanga o waho he paparanga konutea parakore.
2. Te whakapūmau makariri (te whakapūmau hiko, EG)
Tukanga tukatuka: Ka rumakina te paipa maitai ki roto i te irahiko kei roto ngā katote konutea hei katote, ā, ka whakatakotoria he paparanga konutea mā te iahiko tika.
Te kaupapa hanganga paninga:
Te whakatakoto hikohiko: Ka whakaitihia ngā katote konutea (Zn²⁺) hei ngota konutea e ngā irahiko i runga i te mata katote (paipa maitai) hei hanga i tētahi paninga ōrite (karekau he paparanga koranu).

2. Tātari Rerekētanga Tukanga

1. Hanganga paninga

Te whakapūmau wera-tō:
Hanganga paparanga: paparanga → paparanga koranu Fe-Zn → paparanga konutea parakore. He tino mārō te paparanga koranu, ā, he tiakitanga anō hoki.
Te whakapūmau makariri:
Kotahi te paparanga konutea, kāore he whakawhiti koranu, he ngāwari ki te horapa te waikura nā te kino ā-mīhini.
 
2. Whakamātautau piri
Te whakapūmau wera-tuku: Whai muri i te whakamātautau piko, i te whakamātautau hama rānei, kāore e ngāwari te tihore i te paninga (he piri pūmau te paparanga koranu ki te papa).
Te whakapūmau makariri: Tērā pea ka taka te paninga nā te kaha o waho (pērā i te āhuatanga "tihore" i muri i te waru).
 
3. Tikanga ātete waikura
Te whakapūmau wera-tō:
Ānode patunga tapu + parenga ārai: Ka waikura tuatahi te paparanga konutea, ā, ka whakaroa te paparanga koranu i te horapa o te waikura ki te papa.
Te whakapūmau makariri:
Ko te nuinga o te wā ka whakawhirinaki ki te parepare, ā, ka ngāwari te papa ki te waikura i muri i te pakaru o te paninga.

3. Kōwhiringa horopaki tono

3. Kōwhiringa horopaki tono

Ngā āhuatanga e tika ana mō ngā paipa maitai whakarewa wera-tuku
Ngā taiao kino:ngā hanganga o waho (ngā pourewa tuku hiko, ngā piriti), ngā paipa o raro whenua, ngā whakaurunga moana.
Ngā whakaritenga roa mō te manawanui:ngā tūāpapa hanga, ngā ārai o te huarahi.
 
Ngā āhuatanga e tika ana mō ngā paipa maitai piauau makariri
Taiao waikura ngawari:paipa hiko o roto, anga tāonga, wāhanga motuka.
Ngā whakaritenga āhua teitei:te whare taputapu whare, ngā paipa whakapaipai (me whai mata maeneene me te tae ōrite).
Ngā kaupapa e aro nui ana ki te utu:ngā whare rangitahi, ngā kaupapa iti te tahua.
