1. Electroplating kaʻina hana mana
ʻO ke kūlana lawelawe a me ke ola lawelawe o ka uea hao hao a i ʻole ʻāpana pili pili i ka mānoanoa o ka uhi electroplated.ʻOi aku ka paʻakikī o nā kūlana o ka hoʻohana ʻana a ʻoi aku ka lōʻihi o ke ola lawelawe, ʻoi aku ka mānoanoa o ka papa o ka uea hao galvanized e pono ai.ʻO nā huahana like ʻole, e like me ke kaiapuni kikoʻī (ka mahana, ka haʻahaʻa, ka ua, ka haku mele ʻana, a me nā mea ʻē aʻe) e hoʻoholo ai i ke ola lawelawe i manaʻo ʻia o ka mānoanoa o ka uhi ʻana, ʻo ka mānoanoa makapō ke kumu o nā ʻōpala āpau.Akā inā ʻaʻole lawa ka mānoanoa, ʻaʻole ia e hiki i nā koi ola lawelawe i manaʻo ʻia.ʻO nā mea hana like ʻole, e like me kā lākou mau pono ponoʻī, i ka hihia o ka hoʻoholo ʻana i ka plating, ka hoʻomākaukau mua ʻana i kahi kahe kaʻina hana ʻoi aku ka piha a me ke kūpono, nā palena plating maʻemaʻe, ka hoʻokele plating solution concentration, ka hana maʻamau.
2, wela plating uea plating ma hope o ka hana
Post-plating (passivation, hoʻoheheʻe wela, sealing and dehydrogenation, etc.) no ka hoʻonui ʻana i nā waiwai pale, hoʻonaninani a me nā kumu kūikawā ʻē aʻe.Ma hope o ka galvanized, chromate passivation a i ʻole nā hana hoʻololi ʻē aʻe e koi ʻia e hana i ke ʻano like o ke kiʻi hoʻololi, ʻo ia kekahi o nā kaʻina hana e hōʻoia i ka maikaʻi o ka post-plating.
3, kaʻina hana uea galvanized
ʻO nā kī a me nā ʻāpana koʻikoʻi me ka ikaika tensile ʻoi aku ka nui ma mua o 1034Mpa pono e hoʻokuʻu ʻia i ke koʻikoʻi ma 200 ± 10 ℃ no ka ʻoi aku ma mua o 1 hola ma mua o ka plating, a ʻo nā ʻāpana carburized a paʻakikī paha e hoʻokuʻu ʻia i ke kaumaha ma 140 ± 10 ℃ no ka ʻoi aku ma mua o 5 hola.ʻAʻohe hopena o ka mea hoʻomaʻemaʻe i hoʻohana ʻia no ka hoʻomaʻemaʻe ʻana i ka ikaika paʻa o ka uhi ʻana a ʻaʻohe corrosion ma ka substrate.Hiki ke wehe i nā huahana corrosion a me oxide film (ʻili) ma ka ʻili o nā ʻāpana me ka ʻole o ka corrosion nui ma ka matrix.
Hiki ke hana i ka galvanizing e ka zincate galvanizing a i ʻole ka galvanizing chloride.E hoʻohana ʻia nā mea hoʻohui kūpono no ka loaʻa ʻana o kahi uhi i kūpono i nā koi o kēia maʻamau.Pono e hana ʻia ka mālama ʻana i ka luminescence ma hope o ka uhi ʻana i ka luminescence.ʻO nā ʻāpana e pono e hoʻoheheʻe ʻia no ka passivation e hoʻopaʻa ʻia ma hope o ka dehydrogenation.Ma mua o ka passivation, pono e hoʻohana ʻia ka 1% H2SO4 a i ʻole 1% hydrochloric acid e hoʻāla i 5 ~ 15s.E mālama ʻia ka passivation me ka chromate kala ke ʻole i kuhikuhi ʻia ma nā kiʻi hoʻolālā.
ʻO ka noi ākea o ka uea galvanized ua lawe mai i ka ʻoluʻolu nui i ka hana a me ke ola o nā kānaka, akā ʻaʻole e hoʻohaʻahaʻa ʻia ke kaʻina hana o ka uea hao.I ka hana ʻenehana, pono e hoʻomalu pono ʻia ke kaʻina hana o ka uea galvanized e hōʻoia i ka maikaʻi o ka uea galvanized.
