Pehea ka lōʻihi o ka hoʻoheheʻe ʻana a me ka ʻino ʻana o ka alumini?- naRuiqifeng Mea Hou.ʻO ka mea nui oaluminikaʻo ka aluminika a me ka liʻiliʻi o nā mea hao.Manaʻo kekahi poʻe ʻaʻole maʻalahi ka alumini no ka hoʻololi ʻana i ke kala.ʻO ka ʻoiaʻiʻo, ʻo ka alumini he metala ikaika loa, maʻalahi ka oxidize ma mua o ka hao.ʻAʻole ʻike ʻia, no ka mea, ʻo ka alumini oxide i hoʻokumu ʻia ma hope o ka oxidation ʻaʻole kala a ʻike.A ua hoʻokaʻawale kēia papa o ka oxide film i ka alumini kūloko a me ka pilina o ka ea, no laila ʻaʻole ia e hoʻomau i ka oxidate, a pale i ka substrate alumini.No laila paʻa ka alumini me ka ʻolelapaʻau ʻili. Akā ʻaʻole hiki ke pale ʻia ke kiʻi oxide, hiki ke hoʻopau ʻia ka alumini oxide e ka waikawa a me ka alkali.I loko o ke kaiapuni e loaʻa ana i ka ea corrosive, ua maʻalahi ka luku ʻana i ke kiʻi oxide, ka hopena i ka corrosion o ka substrate aluminika, pōʻino.Inā hoʻohana ʻia ma waho, ʻo ka ʻike ʻana o ka lā, a me ka wai ua ʻakika e hoʻolalelale i ka ʻino o ka alumini.No laila pehea ka lōʻihi o kaaluminie oxidate a corrode no hoi e pili ana i kona kaiapuni, a me kalapaʻau ʻili.ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili o nā profiles aluminika e pili ana i ka anodic oxidation, electrophoresis, spraying, electroplating, etc. kū'ē i ka corrosion i loko o ke kaiapuni o waho, a hiki i ke ola lawelawe conservative ke hiki i 25 mau makahiki.E nānā hou aku mawww.aluminum-artist.com
