ʻO ka ʻōwili nui o ka uea galvanized e hoʻopau ikaika ʻia i ka oxygen a e ʻā ana nā huna ahi, ʻoiai ʻo ka poloka sodium a me ka pā magnesium e pio i ka oxygen a ʻaʻohe uila e ʻā.Hoʻoholo ʻia kēia hiʻohiʻona e ka haku ʻana o nā ʻōwili nui o ka uea galvanized.ʻO nā ʻōwili nui o ka uea galvanized i hoʻohana ʻia i ka hoʻokolohua ʻo ka hao puaʻa a i ʻole ka uea kila, ʻo ia mau mea ʻelua o ka hao a me ke kalapona (nā mea paʻakikī i loaʻa nā mea hao a me ke kalapona).Ke hoʻopau ʻia ke kalapona i loko o ka uea galvanized, e hana ʻia ke kalapona dioxide, a e hoʻololi ʻia ka paʻa i ke kinoea, a e emi koke ka leo.
Hiki ke ʻike ʻia ka uea galvanized e like me ka hao i uhi ʻia i ke kalapona, ke pio ʻia, ua like ka ʻili me ka carbon papau hiki ke hoʻopili me ka oxygen, hoʻopuka i ke kinoea carbon dioxide, e wahī iā ia i ka hao (he mokuʻāina hoʻoheheʻe kēia) i loko. aia ma kauwea galvanized, ʻoi aku ka maikaʻi o ka ʻā.ʻO ke kalapona i hoʻopaʻa ʻia i ka hao e like me ka dynamite i loko o kahi ʻeke dynamite, e puhi ana i ka hao i kēlā me kēia manawa.
ʻO ka sodium a me ka magnesium ka liʻiliʻi o nā haumia hiki ke hoʻopau ʻia, a i ka wā e pio ai, ʻā wale lākou.Aia ka Galvanizing i ke kaʻina hana electrochemical i hoʻohana nui ʻia ma ka ʻili o ke kila.No laila, ʻo ka mea mua, no ka mea, ʻoi aku ka paʻa o ka paʻa ʻana o ka zinc (ʻoi aku ma hope o ka hoʻoponopono hou ʻana, e like me ka mālama ʻana i ka chromate a me ka phosphating) i ka lewa a me ka wai, a ʻoi aku ka maʻalahi o ke kaʻina hana galvanized.
Hoʻohana ʻia ka zinc coating ma ke kila a me ka ferrous metala, hoʻohana maʻamau ia no kēlā mau ʻāpana i hoʻopaʻa ʻia i ka lewa a i ʻole ka hana wai, akā ʻo ka zinc coating wale nō i ka wā o ka wai ma lalo o 60 ℃, nā waiwai anode.Ke piʻi aʻe ka mahana, hiki ke hoʻololi a lilo ka zinc i hao i cathode.No laila, no nā ʻāpana i hoʻopaʻa ʻia i ka wai wela (e like me nā paila mahu), ʻo ka iwi zinc ma kahi o 70 microns ka mānoanoa a me ka ʻole.No nā ʻāpana i hoʻohaʻahaʻa ʻia i ka wela haʻahaʻa a i ʻole ka hana lewa, ʻaʻole pono ka uhi zinc me ka ʻole o nā pinholes.
ʻO ka electrolytic deposition o ka ʻōwili uʻa uʻa zinc-chin ʻo ia ke kumu ʻelua ʻano electrolyte: ʻo ka zinc ka mea nui ma ke ʻano o ka zinc cation hydration i ka hopena;Aia ka Zinc i ka hoʻonā e like me ka anion paʻakikī.No ka papa hoʻokahi ka acid electrolyte, cyanide complex a me zincate electrolyte, a ʻo ka nickel sulfate electrolyte ka papa ʻelua.He mea nui ka cyanide electrolyte a me ka acid electrolyte.
