He aha te mea he kowiri tira te atete ki te waikura?

He maha nga konganuku ka hanga he kiriata waikura ki runga i te mata i te wa o te tauhohenga ki te hauora i te rangi.Engari ko te mate, ko nga pūhui i hangaia i runga i te waro waro ka mau tonu te waikura, ka nui haere te waikura i roto i te waa, ka mutu ka puta he kohao.Hei karo i tenei ahuatanga, i te nuinga o te waa ka whakamahia e matou te peita me nga konganuku aukati-waiora (pērā i te zinc, nickel, me te chromium) hei whakakikorua i runga i te mata o te maitai waro.
Ko tenei momo whakamarumaru he kiriata kirihou noa.Mena ka pakaru te paparanga tiaki, ka tiimata te waikura o raro.Kei hea he hiahia, he otinga, a ko te whakamahi i te kowiri tira ka taea te whakaoti i tenei raru.
Ko te parenga waikura o te kowiri tira e whakawhirinaki ana ki te huānga "chromium" i roto i tona hanganga, na te mea ko te chromium tetahi o nga waahanga o te maitai, na reira kaore i te rite nga tikanga tiaki.Ka tae te ihirangi chromium ki te 10.5%, ka tino piki ake te parenga waikura o te hau o te rino, engari ka nui ake te ihirangi chromium, ahakoa ka taea tonu te whakapai ake i te aukati, kaore i te kitea te paanga.
Ko te take i te wa e whakamahia ana te chromium mo te maimoatanga pai o te witi, ka huri te ahua o te waikura o waho ki te waikura mata e rite ana ki tera i hangaia ki te whakarewa chromium parakore.Ko tenei waikura whakarewa chromium-taonga e piri ana ki te tiaki i te mata mai i te whakapouritanga ma te hau.He tino kikokore tenei ahua o te paparanga waikura, a ka kitea te kanapa o waho o te maitai i roto, na te mea ko te kowiri tira he mata whakarewa ahurei.
I tua atu, ki te pakaru te paparanga mata, ka whakatikahia e te waahanga o te mata o te mata me te tauhohenga o te hau me te hanga ano i tenei "kiriata haruru" kia mau tonu te mahi tiaki.Na reira, ko nga tira kowiri katoa he ahuatanga noa, ara, ko te ihirangi chromium kei runga ake i te 10.5%.
