ʻO nā huahana hao nā huahana metala maʻamau i ke ola.Hōʻike ʻia nā huahana hao ma nā wahi āpau o ko mākou ola, akā aia kahi pilikia nui i ka hoʻohana ʻana i nā huahana hao.E ʻōpala nā huahana hao, a i ka wā e puka mai ai ka ʻōpala, e hoʻopilikia ia i ka hoʻohana ʻana a me ke ʻano o nā huahana hao.Hoʻohui i ka hoʻopili non-metallic: hoʻomaʻemaʻe, maloʻo a ʻaʻahu i ka ʻili o nā mea hao a me nā mea kila me kahi papa o nā mea pale, e like me ka ʻaila, ka ʻaila mineral, ka momona-hōʻino, ka plastic a me ka lacquer.
ʻElua ʻano o ka pale electrochemical.ʻO ka hoʻohui ʻana i kahi ʻāpana metala ʻoi aku ka ʻoi aku o ka ʻōlinolino ma mua o ia.No ka laʻana, e hoʻokomo ʻia nā moku a me nā moku me nā poloka zinc.ʻO ka lua, ʻo ia ka hoʻopili ʻana i ka pahu maikaʻi ʻole o ka mana lako, e like me ka hao a me nā laka kahawai kila e hoʻopili pinepine ʻia me ka hopena maikaʻi ʻole o ka mana lako, ma o ka hopena maikaʻi ʻole.ʻO kāna mau ʻano hana: ke kiʻi uhi metala e like me ka electroplating, ka uhi kūlohelohe e like me ka pena, ka papa hoʻololi e like me ka orchid a i ʻole ʻeleʻele, nā mea hou e hoʻololi i ke ʻano metala.
ʻO ka paleʻana i ka'ōpala no ka manawa e hoʻomākaukau ai no ka hoʻopauʻana i ka misionari o ka papa pale e weheʻia.ʻO nā ʻano hana: cajoling corrosion inhibitors, coating antirust oil, peeling molecular compound plastics, hoʻomaloʻo i ka ea, vacuuming, etc. nui, pipiʻi, paʻakikī e hoʻopuka i ka noi ākea.
ʻO ke ʻano hana pale ʻana i ka ʻōpala: uhi ʻia me ka asphalt, ka hale hao, uhi ʻia me ka asphalt, hiki iā ʻoe ke pale i ka ʻōpala.Ka uhi metala: E hana ʻia kekahi ʻili metala i kiʻi ʻoniʻoni oxide, hiki ke uhi ʻia ma ka ʻili o ka metala i haku ʻia o kēia pale metala.E like me: galvanized iron, tinplate plating, bicycle underwire a me kekahi mau mea lapaʻau i uhi ʻia me ka chromium a me ka nickel.
