ʻO ka paʻakikī ka mea maʻamau i hoʻohana ʻia i loko o nā waiwai mechanical o nā mea metala.ʻO kahale hana uwea haohoʻolauna i kahi ʻano hoʻāʻo wikiwiki a hoʻokele waiwai no ka hoʻāʻo paʻakikī.Eia nō naʻe, no ka paʻakikī o nā mea metala, ʻaʻohe wehewehe i hui pū ʻia me nā ʻano hoʻokolohua āpau ma ka home a ma waho.Ma keʻano laulā, manaʻo pinepine ʻia ka paʻakikī o kahi metala ʻo ke kūʻē ʻana o ka mea i ka hoʻololi ʻana i ka plastic, nā ʻōpala, nā ʻaʻahu, a i ʻole ke ʻoki ʻana.
wili nuiuwea galvanizedi loko o ka zinc immersion mamao debugging, e malama i ka kumu mua me ka loli ole, e like me t= KD e hoʻoholo i ka zinc immersion manawa (1), kahi: t ka zinc immersion manawa mau, lawe 4-7D ke anawaena o ke kila uea mm. , a laila koho i ka mamao o ka hoʻokomo zinc.Ma ka hoʻololi ʻana i ka mamao zinc dip, hiki ke hoʻopōkole ʻia ka manawa zinc dip o ka uea kila o nā kikoʻī like ʻole e 5s ma ka awelika.Ma kēia ʻano, hoʻemi ʻia ka hoʻohana ʻana i ka zinc no ke ton o ke kaula kila mai 61kg a i 59.4kg.
Hot dip galvanizing aia i loko o ka wela hoʻoheheʻe zinc wai dip plating, hana wikiwiki, mānoanoa akā ʻaʻole kūlike, ʻae ka mākeke i ka mānoanoa o 45 microns, a hiki i 300 microns ma luna.He pōʻeleʻele kona waihoʻoluʻu, hoʻopau i nā metala zinc hou aʻe, hana i ka papa infiltration me ka metala kumu, a he kūpaʻa maikaʻi ka corrosion.Luu welagalvanizinghiki ke mālama ʻia no nā makahiki he nui i waho.ʻO ka pale o ka zinc coating ma ka hao matrix he ʻelua mau loina: ma ka ʻaoʻao hoʻokahi, ʻoiai ʻoi aku ka ikaika o ka zinc a maʻalahi hoʻi i ka oxidize ma mua o ka hao, akā ʻaʻole i ʻoluʻolu a paʻa kona kiʻi oxide e like me ka hao.ʻO ka papa oxide nui i hoʻokumu ʻia ma ka ʻili e kāohi i ka hoʻoneʻe hou ʻana o ka zinc i loko.
ʻOi aku ma hope o ka passivation o ka papa galvanized, ʻoi aku ka mānoanoa a me ka paʻa o ka ʻili o ka papa oxide, ʻoi aku ka kiʻekiʻe o ke kūpaʻa oxidation.Ma kekahiʻaoʻao, i ka wā o ka ili o kai hooheheeiaUa pōʻino ka papa, e hōʻike ana i ka matrix hao i loko, no ka mea, ʻoi aku ka ikaika o ka zinc ma mua o ka hao, e lawe ka zinc i ke kuleana o ka mōhai ʻana i ka anode zinc, e oxidized ka zinc ma mua o ka hao, i mea e pale ai i ka pae hao ʻaʻole e pōʻino.
