Ma lalo o nā kūlana electrolyte like a me nā kūlana hana kikoʻī, hana ka alumini a me kāna mau mea hoʻohui i kahi kiʻiʻoniʻoni oxide ma ka huahana alumini (anode) ma muli o ka hana o ke au i hoʻopili ʻia. ʻO ke kumu o ka lanakila ʻana i nā hemahema o ka paʻakikī o ka ʻili a me ke kūpaʻa ʻana o ka alumini alloy, hoʻonui i ka laulā o ka noi a hoʻolōʻihi i ke ola lawelawe.
He aha ka anode?
I loko o kahi pākahiko kemika, ʻo ka electrode e hiki ke hoʻoheheʻe i ka electrolyte ua kapa ʻia ʻo anode.
Nui nā ʻano hoʻonā i hoʻohana ʻia i ka anodizing. ʻO ka mea maʻamau i kēia manawa ʻo ia ka sulfuric acid, oxalic acid, malonic acid, sulfonic acid a pēlā aku. ʻO ka mea maʻamau o kēia mau mea ka hoʻohana ʻana i ka sulfuric acid ma ke ʻano he hoʻonā lapaʻau oxidative. ʻO nā pono, hiki ke loaʻa kahi kiʻiʻoniʻoni oxide mānoanoa, nui nō hoʻi ka porosity o ka kiʻiʻoniʻoni oxide, hiki ke hoʻomoʻa maikaʻi ʻia ka mea hoʻopihapiha, nui nā ʻano a me nā kikoʻī o nā mea alumini kūpono, ʻaʻole paʻakikī ka ʻenehana hana, a haʻahaʻa ka hoʻohana ʻana i ka mana.
No ke aha i anodized ʻia ai nā ʻāpana alumini?
1. E uhi i ke ala mīkini.
Ma hope o ka hana ʻana i ka CNC machining, aia nā laina mea hana ma luna o ka ʻili o nā ʻāpana alumini. Inā makemake nā mea kūʻai aku e hoʻomaikaʻi i ke ʻano o nā ʻāpana alumini, koho ka hapa nui o lākou e hoʻohana i ka sandblasting + anode no ka mālama ʻana i ka ʻili.
2. Hoʻomaikaʻi i ke kūpaʻa ʻana i ka pala.
ʻO ka ʻoiaʻiʻo, he metala kūpaʻa i ka pala ka alumini alloy no ka mea he pane nui ka alumini a he maʻalahi loa ia i nā hopena kemika me ka oxygen i ka lewa e hana i ka alumini oxide. ʻAʻole ʻike ʻia ka ʻili alumini oxide moakaka i ka maka kanaka. Hoʻokaʻawale wale kēia ʻili alumini oxide lahilahi i ka lewa i ʻole e oxidized ka substrate alumini. Hana ka ʻili oxide kūlohelohe ma ke ʻano he anti-oxidant.
3. Hoʻomaikaʻi i ke kūpaʻa ʻana i ka ʻaʻahu.
He mea maʻalahi loa ka alumini i nā ʻōpala a me ke komo ʻana, a ʻaʻole hiki ke hoʻohālikelike ʻia ka paʻakikī o nā mea hoʻohui alumini me ke kila ma hope o nā mea āpau. He paʻakikī loa ka ʻili o ka ʻaoʻao alumini ʻoihana anodized, a hiki i ka paʻakikī o ka ʻili oxide i 300HV. No laila, he kūpaʻa loa ia i ke komo ʻana a ʻaʻole maʻalahi ke kahakaha.
4. Ka waihoʻoluʻu ʻili o nā huahana alumini hoʻonaninani.
Ma mua o ka anodization alumini a me ka sila ʻana, he nui nā pores mānoanoa ma ka ʻili, kahi e maʻalahi ai ke omo i nā paʻakai metala a me nā dyes, a ʻo ka ʻili o nā huahana alumini e hana i nā kala kala.
5. E hoʻomaikaʻi i ka pale ʻana.
Hoʻokele maikaʻi loa ka alumini i ka uila, akā pono ka insulation i kekahi mau hihia. ʻAʻole conductive ka ʻili alumini oxide anodized.
6. E hoʻomoʻa mua i ka pena.
Pono e pena ʻia kekahi mau ʻili alumini. Loaʻa i ka ʻili o ka alumini anodized ka adsorption ikaika, a ʻoi aku ka like a me ka nani o ka uhi ʻana.
ʻO ka mānoanoa o ke kiʻiʻoniʻoni maʻamau o ka anodizing maʻamau o ka ʻāina he 10-20 microns.
No ke aha he mea pono ai ka anodizing?
Ma kekahi ʻaoʻao, ma muli o ke kiʻi ʻoniʻoni oxide like ʻole i hoʻokumu kūlohelohe ʻia, ʻokoʻa a maikaʻi ʻole ke kala o ka ʻili alumini.
Ma ka ʻaoʻao ʻē aʻe, he lahilahi ka ʻili oxide i hana maoli ʻia, maʻalahi ka hōʻino ʻia, a nāwaliwali i ke kūpaʻa ʻana i ka pala. ʻO ke ʻili oxide artificial i hana ʻia e ka anodic oxidation he like, mānoanoa a kūpaʻa i ka ʻaila pala.
