wili nuiuwea galvanizedua hoʻokumu ʻia e ke kaha kiʻi uea, ʻo ke kiʻi uea he kaʻina hana, hiki ke hana i ka huahana e hoʻokō i ke ʻano i koi ʻia a hoʻokō i nā waiwai mechanical maʻamau.Hana ʻia ke kaha uea anuanu ma ka mahana recrystallization, lawe ʻia ke kaha uea wela ma ka mahana crystallization, huki ʻia ke kaha uea mahana ma ke kiʻekiʻe ma mua o ka mahana a haʻahaʻa ma mua o ka wela crystallization.He kiʻi kiʻi maʻamau ke kiʻi anu.ʻO ke kiʻi wela ka wela o ka uea ma mua o ke komo ʻana i ka lua make.Hoʻohana nui ʻia no ke kaha kiʻi ʻana i ka uea me ka helu heheʻe kiʻekiʻe.
Lawe ʻia ke kaha kiʻi wela ma ka hoʻomehana ʻana i ka mea wela i ka pae wela i ʻōlelo ʻia, hoʻohana nui ʻia no ke kaha kiʻi ʻana o ke kaula kila galvanized, paʻakikī ke deform.Uea hao haoua hana ʻia ma ke kaʻina hana kiʻi, ka hoʻokumu ʻana i nā kikoʻī maʻamau o ke kaula kila, a laila i loko o ka pahu electroplating ma o ka unidirectional zinc plating i kēia manawa ma ka ʻili.He lohi ka wikiwiki o ka hana ʻana, ʻo ka zinc layer o ka zinc galvanized he ʻano like ʻole, ʻano lahilahi ka mānoanoa, maʻamau i ka 3 ~ 15 microns, kiʻekiʻe loa ka ʻōlinolino, akā ʻilihune ke kūpaʻa o ka corrosion, a ʻōlelo ʻia e kūʻai. e like me ke koi i ka wā e hoʻohana ai.
ʻO ka hoʻohana ākea o ka nuiuwea galvanizedʻO ka nui o nā huahana ma muli o kona hopena anti-rust a me ka anti-corrosion, no ka mea, he hopena pale nui ka zinc i ke ʻano o ka huahana, no laila e hoʻomaikaʻi nui ai i ka hana a me nā hiʻohiʻona o ka huahana ponoʻī, i mea e hoʻolaha ai i ka noi o ka huahana. huahana.ʻO ka papa zinc o ka uea zinc me ka papa zinc mānoanoa he crystallinity maikaʻi, ʻaʻahu a ʻaʻohe ʻole, a me ke kūpaʻa maikaʻi ʻana i ka corrosion.
ʻO ka papa zinc i hana ʻia e ka electrogalvanizing he maʻemaʻe loa a he lohi ka corrosion i ka waikawa a me ke kinoea alkali, wai a me ka noe, hiki ke pale pono i ka matrix kila.Hiki ke mālama ʻia ka papa Galvanized e ka chromic acid passivation i loko o nā ʻano kala, nani a lokomaikaʻi, me nā mea hoʻonaninani maikaʻi.ʻO ka papa zinc ma luna o ka uea galvanized he ductility maikaʻi a hiki ke hoʻoheheʻe ʻia ke anuanu, ʻōwili, kulou a me nā hana ʻē aʻe me ka ʻole e hōʻino i ka papa zinc.
