SPA-Hkila hoʻowaliwali, ʻike ʻia hoʻi ʻo ke kila corrosion-resistant atmospheric, e pili ana i kahi ʻano haʻahaʻa haʻahaʻa.huikaukila ikaika kiʻekiʻe
i loko o kahi liʻiliʻi o nā mea hoʻohuihui, ke kumu kūʻai haʻahaʻa, a me ke kūpaʻa corrosion maikaʻi i ka lewa. ʻO ka alloying nui
ʻO nā mea kumu he Cu, P, Cr, Ni, Si, Mn, V, RE, etc. I ka wā o ka hoʻohana ʻana i ke kila ʻino, kahi kiʻiʻoniʻoni pale paʻa a paʻa.
E hoʻomaka mālie nā huahana corrosion ma ka ʻili e pale aku i ka oxygen, ka wai a me nā mea ʻino ʻē aʻe i ka lewa
e hoʻopōʻino hou i ka substrate, no laila e hoʻemi nui ʻia ka nui o ka corrosion e like me ke kila kalapona. . Ma muli o kona ikaika kiʻekiʻe a
kumukūʻai kūpono, ʻoi aku ka haʻahaʻa o ke kumukūʻai hana ma mua o ke kila kila. ʻO ke kūlana hoʻokō SPA-H: JISG3125-2015.

1) ʻO SPA-H he kila hoʻoheheʻe no ka hoʻoili ʻana i ka pahu, ʻoki a me ka wili. Hoʻohana nui ʻia ʻo SPA-H no nā ipu moku,
nā alahaka kila, nā moku a me nā pahu e pale ai i ka ʻino o ka lewa.
2) Hoʻohana nui ʻia ke kila SPA-H e hana i nā ipu. He moʻolelo oi aku ka moʻolelo o ka ʻoihana halihali ipu hao
50 makahiki ma ka honua. He 30 mau makahiki i hala aku nei, ua nele ka lawe ʻana i ka ipu hao o koʻu ʻāina. Mai ka hoʻoponopono ʻana a me ka wehe ʻana, koʻu ʻāina
Ua hoʻomau ke kūkulu ʻana i ke awa a me ka lawe ʻana i nā ipu hao. ʻOi aku i nā makahiki i hala iho nei, ua alo ke kaiāulu honua
ʻo ke kūlana o "hoʻokahi pahu paʻakikī ke loaʻa.
5. Kumu kūʻē ʻino:
Ke ʻike ʻia ke kila i ka lā a me ka makani, ʻoi aku ka mea nui o kona pale ʻana i ka corrosion. Ma hope o ka hoʻohui ʻana i ka phosphorus, keleawe, chromium,
nickel a me nā mea ʻokoʻa ʻē aʻe i ke kila, e hoʻokumu ʻia kahi kiʻiʻoniʻoni pale a ikaika ma ka ʻili o ka mea keleawe, kahi
hiki ke pāʻani i kekahi kuleana pale.
