He maikaʻi ka hoʻololi ʻana o ka uea a me ka elongation, hiki ke kū i ke kaomi o ka hana mechanical, i ko mākou ʻāina ʻoihana i hana nui loa.Nui na ano o ka uwea hao.ʻO nā mea maʻamau he uwea hao ʻeleʻele auwea hao hao.Ua hoʻomaikaʻi maikaʻi ʻia ka pale ʻana o ka corrosion o ka uhi waho, akā e ʻike ʻia ke ʻano o ka corrosion crevice ma hope o ka hoʻohana lōʻihi.
ʻO Crevice corrosion kahi ʻano corrosion ma kahi liʻiliʻi, ʻoi aku hoʻi ma kahi huna, hiki ke hana i ka pōʻai kino kino.Aneane hiki i ka crevice corrosion ke hana i loko o ka metala metala, me ke kinoea i loaʻa i ka anionic neutral medium Z he maʻalahi ke kumu i ka corrosion crevice, hiki pinepine ka corrosion crevice i ka puka o 0.025 a 0.1 mm, no ka lōʻihi o ka hōʻiliʻili ʻana, mau nā māwae. he moʻo haumia, hui pū ʻia me ke kaiapuni o waho o ka pulu maʻalahi hiki ke ʻino i ka wahi o ka ʻāpana he liʻiliʻi.
ʻO ka loaʻa ʻana o ia mau mea haumia i ka wā lōʻihi e hopena i ka hoʻololi a me ka corrosion āpau.ʻO ka hoʻonā pololei i kēia hanana ka hoʻoikaika ʻana i ka uhi o ka mea e pale aku ai i ka corrosion.ʻO ka lōʻihi o ka pale ʻana o ke kaula hao galvanized e pili nui i ka mānoanoa o ka uhi.ʻO ka ʻōlelo maʻamau, i ke kinoea maloʻo maloʻo a me ka hoʻohana ʻana i loko, a i nā kūlana kūlohelohe koʻikoʻi, pono ke kiʻekiʻe loa ka mānoanoa papa galvanized.No laila, i ke koho ana o ka mānoanoa papa galvanized e noonoo i ka hopena o ke kaiapuni.
Ma hope o ka mālama ʻana i ka passivation o ka papa galvanized, hiki ke hana ʻia kahi kiʻiʻoniʻoni passivation waihoʻoluʻu a nani, hiki ke hoʻomaikaʻi nui i kāna hana pale a me ka hana hoʻopaʻa ʻana.Nui nā ʻano hoʻonā zinc plating, hiki ke hoʻokaʻawale ʻia i ka solution plating cyanide a me ka solution plating free cyanide e like me kā lākou mau waiwai.ʻO ka cyanide zinc plating solution ka hiki ke hoʻopuehu maikaʻi a me ka hiki ke uhi, ʻoluʻolu a meticulous ka coating crystallization, maʻalahi ka hana, ākea ka laulā noi, a ua hoʻohana ʻia i ka hana ʻana no ka manawa lōʻihi.Eia nō naʻe, ʻoiai he cyanide ʻawaʻawa loa ka hopena plating, ʻo ke kinoea e pakele ana i ke kaʻina plating he mea pōʻino i ke olakino o nā limahana, no laila pono e mālama pono ʻia ka wai ʻino ma mua o ka hoʻokuʻu ʻana.
