Ua hoʻohana ʻia ʻo Hot dip galvanizing no nā makahiki he 150, a ʻaʻole i loli kona kumu i kēia manawa.Pono e hoʻokomo piha ʻia ka hale kila i ka zinc i ka manawa hoʻokahi e hoʻokō i ka hoʻolālā kiʻi galvanized like.Inā lōʻihi a laula paha ʻo ia e luʻu ʻia i ʻelua manawa, e ʻike ʻia ka papa zinc ma ka hui ʻana he ʻanoʻala, mānoanoa loa a pēlā aku.Eia kekahi, inā he kaumaha loa ka paona hoʻokahi o ka hale kila, e paʻakikī kāna hana inā ʻoi aku ia ma mua o ka ukana o nā lako galvanizing.No laila, e kamaʻilio me ka hale hana galvanizing wela ma mua.
ʻO ka mea o ke kila kila e pili i ka hoʻonohonoho a me ka mānoanoa o ke kiʻi ʻoniʻoni wela wela.No ka laʻana, ke kila kiʻekiʻe kiʻekiʻe i loko o ke silikoni, ʻoi aku ka kiʻekiʻe o ke kalapona, maʻalahi ke pane koke me ka zinc hoʻoheheʻe ʻia, ʻo ka hopena o ka ulu nui ʻana o ka alloying, e hoʻoulu i kahi hiʻohiʻona ʻeleʻele hina, akā ʻaʻole pili i kona kūpaʻa corrosion.A i ʻole ke kila wela, inā ʻoi aku kona ikaika tensile ma mua o 90kg/mm2, ma hope o ka hana wela wela, maʻalahi e hōʻemi i kona ikaika, etc.
ʻO ka hui pū ʻana o nā metala ʻokoʻa, e like me ke kila a me ke keleawe, ka tin, ke kēpau a me nā metala non-ferrous ʻē aʻe, i ka wā o ka hana wela, ʻo ka hoʻoheheʻe ʻana o kēia metala ʻole e hoʻololi i ke ʻano kiʻi zinc.E like hoʻi me ka hui pū ʻana o ke kila kahiko a me ke kila hou, i ka hana pickling, maʻalahi ka mea hou i ka pickling.Eia kekahi, e like me ka ʻāpana o nā ʻāpana i hana ʻia, ʻoi aku ka nui o ka pickling ma ka wahi hana.
ʻO ke kumu o ka galvanizing wela, ʻo ia ka hoʻokomo ʻana i nā ʻāpana hao maʻemaʻe i loko o ka ʻauʻau zinc ma o Flux wetting, i hana ke kila me ka zinc hehee e hana i kahi kiʻi ʻili i hoʻohui ʻia.
