whakarōpūtanga
Kua wehea te ngongo tapawha piauau ki te ngongo tapawha piauau wera me te ngongo tapawha piauau makariri mai i te tukanga whakaputa.Na te mea he rereke te tukatuka o enei ngongo tapawha piauau e rua he maha nga ahuatanga o te tinana me te matū.I te nuinga o te waa, he rereke nga ahuatanga o te kaha, te uaua me nga taonga miihini.
Hot dip piauau ngongo tapawha: he ngongo tapawha e paiherea ana i muri i te pereti maitai ranei Unuhia maitai te hurihia, ka hanga, a ka hanga i muri i te raupapa o tauhohenga matū i roto i te poka wai piauau wera wera i runga i te kaupapa o tenei ngongo tapawha.Ko te tukanga whakaputa o te ngongo tapawha piauau wera-wera he ngawari noa iho, he tino tiketike te mahi whakaputa, he maha nga momo me nga whakaritenga.Ko tenei ngongo tapawha he iti noa nga taputapu me nga moni, he mea pai mo te hanga o nga kaihanga ngongo tapawha iti.Engari mo te kaha, ko te kaha o tenei momo putorino maitai he iti rawa atu i te paipa tapawha kore.
Pupa tapawha piauau makariri
Na te ngongo tapawha piauau matao ko ki te whakamahi i te parau tumu o te piauau makariri i runga i te ngongo tapawha whakamahia ki te hanga i te ngongo tapawha he mahi anti-waikura.Rerekē i te wera piauau, matao galvanizing paninga te nuinga whakamahi mātāpono hiko ki te aukati i te waikura, na he mea tika ki te whakarite whakapā tonu i waenganui i te konutea paura me te maitai ki te whakaputa i te rerekētanga pūmanawa hiko, na he tino nui maimoatanga mata maitai.
Rerekētanga i waenganui i wera me te matao piauau
ngongo tapawha piauau ngā ngongo tapawha piauau wera me te ngongo tapawha electrogalvanized.Ko te ngongo tapawha piauau wera wera ko te tikanga maku, ko te tikanga maroke, ko te tikanga zinc arataki, ko te tikanga whakaheke o te waikura, me etahi atu. o te galvanizing i muri i te horoi waikawa pickling o te paipa maitai.I tenei wa, ko te tikanga maroke me te tikanga redox te nuinga e whakamahia ana i roto i te whakaputanga, ka whakaatuhia o raatau ahuatanga ki te tepu.Ko te mata o te paparanga konutea he tino maeneene, he matotoru me te rite;He pai nga ahuatanga miihini me te aukati waikura;Ko te kohi konutea he 60% ~ 75% iti iho i tera o te wera wera.Electrogalvanizing he etahi uaua hangarau, engari me whakamahi mo te paninga kotahi-taha, paninga rua-taha ki te matotoru paninga rerekē i runga i roto me waho mata, me te angiangi taiepa ngongo ngongo piauau.
