Pepa Galvanized a me ka ʻili kila kuhiliʻole
ʻO ka pepa galvanized e pale aku i ka corrosion o ka ʻili o ka pā kila mānoanoa a hoʻonui i kona ola lawelawe.
Hoʻopili ʻia ka ʻili o ka pā kila mānoanoa me kahi papa zinc metala.
ʻO kēia ʻano galvanized cold rolled steel sheet he kapa galvanized sheet.
Hoʻohana nui ʻia nā huahana galvanized strip hot-rolled i nā ʻoihana hana, e like me ke kūkulu ʻenehana, ʻoihana māmā, nā trolleys, mahiʻai, mahiʻai holoholona a me ka lawaiʻa, a me nā lawelawe kalepa.
Ma waena o lākou, kūpono ka ʻoihana kūkulu hale no ka hana ʻana i nā huahana ʻoihana pale corrosion a me nā pale kila kala a me nā grills o ka hale o nā hale ʻoihana;
hoʻohana ka ʻoihana metallurgical e hana i nā mea pono hale, nā kapuahi kīwila, nā lako kīhini, a me nā mea ʻē aʻe.
a ua kūpono ka ʻoihana hana kaʻa no ka hana ʻana i nā kaʻa.
Nā ʻāpana anti-corrosion.
ʻO ka mahiʻai, ka mahiʻai holoholona a me ka lawaiʻa e hoʻohana nui ʻia no ka mālama ʻana i ka meaʻai a me ka lawe ʻana,meaʻai ʻiʻo a me ka iʻa iʻa hoʻoheheʻe ʻia a me nā lako hana, etc.ʻO nā lawelawe ʻoihana i hoʻohana nui ʻia no ka hoʻolako ʻana i nā mea waiwai, mālama a me nā lako lako.
ʻO ke kila kila i kū i nā mea palupalu palupalu e like me ke kinoea, ka mahu,ka wai a me nā mea hoʻomāinoino kemika e like me nā waikawa, nā alkali a me nā paʻakai.
ʻIke ʻia hoʻi ʻo ke kila kuhiliʻole a me ke kila ʻakika.
I kekahi mau noi, ke kila kū'ē i nā mea ʻino palupalu i kapa pinepine ʻia he kila kila,ʻoiai ua kapa ʻia ke kila kūpaʻa i nā mea solvent.
E like me kāna hana, hoʻokaʻawale ʻia nā papa kila kila i ke kila austenitic, ke kila ferritic,ke kila ferritic, ka hale metala ferritic (duplex) pā kila kuhiliʻole a me ka hoʻonā ʻana i ka pā kila kuhili ʻole.
Eia hou, hiki iā ia ke hoʻokaʻawale i loko o ka chromium stainless steel plate, chromium-nickel stainless steel plate a me ka chromium manganese nitrogen stainless steel plate.
ʻO ke kumu
Ke emi nei ka pale ʻana i ka corrosion o ke kila kila kila me ka hoʻonui ʻia o ka ʻike kalapona.
No laila, he haʻahaʻa ka ʻike kalapona o ka hapa nui o nā pā kila kila, ʻaʻole ma mua o 1.2%,a ʻo ka Wc (maʻiʻo kalapona) o kekahi mau kila ma lalo o 0.03% (no ka laʻana, 00Cr12).
ʻO ka mea nui alumini alumini i loko o ka pā kila kila ʻo Cr (chromium).
Aia wale nō ke ʻoi aku ka nui o ka wai o Cr i kekahi waiwai, ʻoi aku ka pale ʻana o ke kila.
No laila, ʻo ka nui o ka wai Cr (chromium) wai o nā pā kila kila ma ka liʻiliʻi he 10.5%.
Aia i loko o ka pā kila kila nā mea e like me Ni, Ti, Mn, N, Nb, Mo a me Si.
ʻAʻole maʻalahi ka paʻi ʻana o ke kila kila kila, ka pala, ka ʻōpala, a i ʻole ka pōʻino.
Ma waena o nā mea metala composite no ka hoʻohana ʻenekinia, ʻo nā pā kila kila kekahi o nā mea maka me ka ikaika compressive kiʻekiʻe loa.
E like me ka papa kila kuhiliʻole i maikaʻi corrosion kū'ē.
Hiki iā ia ke hana i nā lālā hoʻolālā e mālama mau i ke kūlike o ka hoʻolālā ʻenekinia hale.
Loaʻa ka paʻakikī o ka paʻakikī a me ka ductility kiʻekiʻe i ka pā kila stainless steel me ka chromium.ka mea maʻalahi no ka hana ʻana, ka hana ʻana a me ka hana ʻana i nā ʻāpana, a hiki ke noʻonoʻo ʻia nā pono o nā mea kākau a me nā mea hoʻolālā holoʻokoʻa.
