He aha nā ʻano anodizing like ʻole i hoʻohana ʻia maalumini?
ByRuiqifeng Mea Houat www.aluminum-artist.com
ʻO ke kumu kumu o ka Anodizing o nā profile alumini ma o ka hopena electrochemical, akā aia kekahi mau ʻano anodizing.
ʻEkolu mau ala maʻamau: ʻakika oxalic, ʻakika sulfuric a me ka waikawa chromic.Loaʻa i kēia mau ʻano anodizing ko lākou ʻano ponoʻī.I kēia lāRuiqifeng Mea Houe hāʻawi iā ʻoe i kahi hoʻolauna pōkole o nā ʻano anodizing like ʻole i hoʻohana ʻia ma nā ʻaoʻao alumini.
1. ʻO ke ʻano o ka sulfuric acid, ʻo ia ke ʻano maʻamau no ka oxidation anodic o nā kiʻi alumini, ʻo ke kiʻi ʻoniʻoni i hoʻokumu ʻia e kēia ʻano he kala ʻole a maopopo, a he maikaʻi ka hana absorption kala, i kūpono no ka kala ʻana.He mea maʻalahi a paʻa ka haku mele electrolyte, maʻalahi e hana, a ʻo ka mea nui, he haʻahaʻa ke kumukūʻai.
2. ʻO ke ʻano o ka waikawa Oxalic: ʻoi aku ka kiʻekiʻe o ka mānoanoa o ke kiʻi oxide i hana ʻia ma kēia ʻano, a e lawe mai i kekahi mau kala hoʻonaninani.Eia nō naʻe, he kumukūʻai kēia ʻano hana a koi i ka nui o ka ikehu uila.
3. ʻOi aku ka lahilahi o ke kiʻi anodizing chromic acid ma mua o ke kiʻiʻoniʻoni anodizing sulfuric acid, a keʻokeʻo a ʻeleʻele paha, e like me ka hopena o ka hoʻoulu ʻana i ka ʻili.Akā ʻaʻole kūpono ka oxidation chromic acid no ke kala.Eia kekahi, ʻo ka hexavalent chromium i loko o ka chromic acid solution he mea ʻawaʻawa loa, a he kiʻekiʻe ke kumukūʻai hoʻonā a me ke kumukūʻai hana, no laila ʻaʻole i hoʻohana ʻia kēia ʻano.
4. Aia kekahi ʻano hana oxidation hou ma Iapana - sulfuric acid-oxalic acid oxidation method, e hoʻomoʻa i nā pono o nā ʻano ʻelua a lilo i ke ʻano o ka oxidation nui ma Iapana.
