Tāpiritanga me te whakariterite i ngā kapa hiriwa

Ko te pepa karioi he paparua paraihe e whai ana i te takotoranga o te rīni i runga i te āhua. Ko te whakakarioi he ara tawhai me te whai hua nui ki te whakaiti i te pāpaku, e whakamahia ana, ā, ko te haurua o te rīni o te ao e whakamahia ana i tēnei tikanga.

Ko te tuanui o te pepa karioi

Ko te pepa paraihe karioi kia whakaiti i te pāpaku ki te āhua o te paparua kia roa ake te ora, e whakaputua ana i te takotoranga o te rīni ki te āhua o te paparua, ko te paparua rīni-karioi i te pepa karioi.

Whakawhaninga o te pepa karioi

E ai ki te whanonga me te tikanga hanga ka wehea ki ngā wāhanga e whai ake nei:

①Ko te papa koura whakaputua ki te waiariki. Ko te papa mātā kua whakaurua ki te kātote waiariki kia pakaru ai te mata ki te takotoranga waiariki. I te wā kua oti te whakaputa, ko te tikanga ko te tikanga whakaputanga tata, arā ko te whakauru tata o ngā papa hōhonu ki ngā kātote waiariki kia waiariki ai ngā papa koura;

② Ko te papa koura huinga. Ko te papa koura hoki kua hangaia ki te koura waiariki, engari i muri i te wehenga o te kātote, ka whakaputua tētahi paku paku ki te 500 ° C kia rere ai te kiriata huinga o te waiariki me te tōka. Ko te papa waiariki he pai te here, te whakauru anō hoki o te takotoranga.

③ Ko te papa koura waiariki. Ko te papa koura kua hangaia ki te whakapai a-ihi he pai te whakamahi. Heoi anō, ko te takotoranga he iti noa, ā, kāore te here ake i te pai ake i te papa waiariki kua pakaru.

④ Pātītī tāone kotahi me te pāparu tarutaru kōtahi. Ko te pāparu kōtahi tarutaru, arā, ngā hua e tarutaru ana tarutaru anake i tētahi taha. He pai ake te whakauru ki te wīra, ki te whakapiri, ki te whakamaru i te mōra, ki te whakapai, me ētahi atu taha ki te pāparu kōtahi tarutaru. Kia whakapai ai i te ngoikera o te karekau o te tarutaru i tētahi taha, kei te tarutaru pāparu kua whakapiria ki te rāpua tarutaru iti ki te taha tuarua, arā, ko te pāparu tarutaru kōtahi rerekē.

⑤ Ngota, pāparu tarutaru huinga. Ko tētahi pāparu i hangaia mai i te tarutaru me ētahi atu taranu pērā i te arumini, te mātā, te tarutaru, me te taea hoki te whakapiri huinga. Kāore anō te pāparu e whakamaru i te mōra, engari he pai hoki tana whakapiri.

Kei reira anō ngā rāwekenga e rima i runga ake nei, kei te wātea hoki te pāparu tarutaru kua tīapua, te pāparu tarutaru kua whakapiria kua takotoria, te pāparu tarutaru kua whakapiria ki te polyvinyl chloride, me ētahi atu anō hoki. Engari ko te nuinga o te wā he tarutaru paraihe te nuinga o te wā.

Ko te āhua o te paraihe galvanized

Te āhua o te mata: Ko te wehe kia rerekē ngā tikanga whakamahia i te hōanga tāwhai, ko te āhua o te mata o te paraihe tāwhai e wehea ana, pērā i te koura tāwhai noa, te koura tāwhai iti, te koura tāwhai rite, te koura tāwhai, me te āhua o te phosphating.
