Ma hope o ka hoʻokō ʻana o nā ʻenekini mīkini ʻo Chengshuo Hardware i ka mīkini kikoʻī a me ka hoʻāʻo ʻana i ka nui prototype o nā huahana metala, e hana kā mākou ʻoihana hoʻoponopono huahana i ka hoʻomaʻemaʻe hou ʻana o nā huahana metala e like me ke kaiapuni kahi e hoʻohana ai nā mea kūʻai aku i nā huahana metala.
Manaʻo ka poʻe he nui i ka mālama ʻana i ka ʻili, a manaʻo paha lākou he hoʻopau nani e like me ka pena a me ka uhi pauda e hoʻonani ai i nā ʻāpana a hoʻololi i ke kala.ʻO ka ʻoiaʻiʻo, ʻaʻole no ka aesthetics wale nō ka mālama ʻana i ka ʻili.Hana ʻia nā ʻano lapaʻau like ʻole i waho o nā huahana metala ma o ka hoʻopili ʻana i kahi papa hoʻohui lahilahi ma ka ʻili.Hiki ke kōkua ka mālama ʻana i ka ʻili i nā ʻano like ʻole o nā huahana metala i hoʻopaʻa ʻia e loaʻa ka palekana maikaʻi aʻe i ka hoʻohana ʻana (e like me ke kūpaʻa ʻana i ka corrosion, hoʻolohi i ka ʻōpala), pale i nā huahana metala, a hoʻokō i ka pahuhopu e hoʻonui i ke ola lawelawe.
I kēia lā e hōʻike aku mākou iā ʻoe i ka hana ʻana o ka huahana alumini a me ka mālama ʻana i ka ʻili, anodizing, kahi mea akamai loa ʻo Chengshuo Hardware.
He aha ka anodizing？
ʻO ka Anodizing kahi hana electrochemical e hoʻohuli ai i kahi ʻili metala i mea hoʻonaninani, kūpaʻa, a me ka corrosion-resistant anode oxide surface.He kūpono loa ka alumini no ka anodizing, ʻoiai ʻo nā metala non-ferrous ʻē aʻe e like me ka magnesium a me ka titanium hiki ke anodized.
I ka makahiki 1923, ua hoʻohana mua ʻia ka anodizing ma kahi pālākiō ʻoihana e pale i nā ʻāpana alumini o nā mokulele moana mai ka corrosion.I nā lā mua, ʻo ka chromic acid anodizing (CAA) ke kaʻina hana i makemake ʻia, i kekahi manawa i kapa ʻia ʻo ke kaʻina Bengough Stuart, e like me ka wehewehe ʻana ma ka UK Defence Specification DEF STAN 03-24/3.
ʻO ka hoʻohālikelike kaulana i kēia manawa o ka anodizing
Ua hoʻohana nui ʻia ʻo Anodizing i ka ʻoihana no ka manawa lōʻihi.Nui nā ala e hoʻohana ai i nā inoa like ʻole, a aia kekahi mau ʻano hoʻohālikelike e hiki ke hōʻuluʻulu ʻia penei:
Hoʻokaʻawale ʻia e ke ʻano o kēia manawa: DC anodizing;AC anodizing;A me ka pulse anodizing o kēia manawa, hiki ke hoʻopōkole i ka manawa hana e hoʻokō ai i ka mānoanoa i koi ʻia, e hana i ka papa kiʻiʻoniʻoni mānoanoa, ʻaʻahu a paʻa, a hoʻomaikaʻi nui i ka pale ʻana i ka corrosion.
Wahi a ka electrolyte, hiki ke hoʻokaʻawale ʻia i ka sulfuric acid, oxalic acid, chromic acid, mixed acid, a me ka anodic oxidation kūlohelohe me ka sulfonic organic acids e like me ka hopena nui.Ua hoʻopaʻa ʻia ʻo Oxalic acid anodizing ma Iapana i ka makahiki 1923 a ma hope i hoʻohana nui ʻia ma Kelemania, ʻoi aku hoʻi i nā noi kūkulu.He mea hale kaulana ka anodized alumini oxide extrusion i nā makahiki 1960 a me 1970, akā ua hoʻololi ʻia ma hope e nā plastics cheap a me ka pauka.ʻO nā kaʻina hana phosphoric acid kekahi o nā mea hou loa i ka mālama mua ʻana i nā ʻāpana alumini i hoʻohana ʻia no ka hoʻopaʻa ʻana a i ʻole ke pena.Ke hoʻololi mau nei nā loli paʻakikī i ke kaʻina hana hoʻoneʻe anodic me ka hoʻohana ʻana i ka waikawa phosphoric.ʻO ke ʻano o ka pūʻali koa a me nā kūlana ʻoihana e hoʻokaʻawale i nā kaʻina anodizing e pili ana i nā hiʻohiʻona o ka uhi ʻana me ka ʻike ʻana i ka kemika kaʻina.
E like me nā waiwai o ka papa kiʻiʻoniʻoni, hiki ke hoʻokaʻawale ʻia i: kiʻiʻoniʻoni maʻamau, kiʻiʻoniʻoni paʻakikī (kiʻiʻoniʻoni mānoanoa), kiʻi ceramic, papa hoʻololi ʻālohilohi, papa pale semiconductor, etc. no ka anodizing.
Hoʻokaʻawale i nā kaʻina hana anodizing no nā huahana alumini
Hoʻohana ʻia ke kaʻina hana anodizing no ka mīkini alumini i ʻike ʻole ʻia (ʻaʻole i uhi ʻia) a i ʻole nā mea wili kemika e pono ai ka pale anti-corrosion.Hoʻokomo ʻia nā ʻāpana anodic i ka chromic acid (CAA), sulfuric acid (SAA), phosphoric acid, a me ka boric acid sulfuric acid (BSAA) anodizing.ʻO ke kaʻina hana anodizing e pili ana i ka mālama electrolytic o nā metala, kahi i hoʻokumu ʻia ai kahi kiʻi paʻa a i ʻole ka uhi ʻana ma ka ʻili metala.Hiki ke hana ʻia nā uhi anodic ma luna o nā alumini alumini i nā electrolytes like ʻole me ka hoʻohana ʻana i ke ʻano o kēia manawa a i ʻole ke au pololei.
Loaʻa ʻia ka anodizing ma ka hoʻokomo ʻana i ka alumini i loko o kahi ʻauʻau electrolyte acidic a me ka hele ʻana i kēia manawa ma ka waena.Hoʻokomo ʻia ka cathode i loko o ka pahu anodizing;Hana ʻia ka alumini ma ke ʻano he anode, e hoʻokuʻu ana i nā ion oxygen mai ka electrolyte a hoʻopaʻa ʻia i nā atom alumini ma ka ʻili o ka ʻāpana anodized.No laila, ʻo ka anodizing kahi mea hoʻomake nui e hoʻonui ai i nā hanana kūlohelohe.
Anodization Aia ka ʻano I, ʻano II, a me ke ʻano III.ʻO ka anodizing kahi kaʻina hana passivation electrolytic i hoʻohana ʻia e hoʻonui i ka mānoanoa o ka papa oxide kūlohelohe ma ka ʻili o nā ʻāpana alumini.Hoʻopili ʻia nā ʻāpana alumini (no laila ua kapa ʻia ʻo "anodizing"), a ke kahe nei kēia manawa ma waena o lākou a me ka cathode (maʻamau he koʻokoʻo alumini palahalaha) ma o ka electrolyte i ʻōlelo ʻia ma mua (ʻoi loa ka sulfuric acid).ʻO ka hana nui o ka anodizing ka hoʻonui ʻana i ke kūpaʻa corrosion, ka pale ʻana i ka pale, adhesion i ka pena a me ka primer, etc
PIC na Corlee:ʻAno IIIʻāpana alumini anodized
Hoʻokumu ʻia ka hoʻolālā anode oxide mai kahi substrate aluminika a ua haku ʻia me ka alumini oxide.ʻAʻole hoʻohana ʻia kēia ʻano alumina i ka ʻili e like me ka pena a i ʻole ka uhi ʻana, akā ua hoʻopili piha ʻia me ka substrate alumini i lalo, no laila ʻaʻole ia e haki a ʻili paha.He hale porous i kauoha ʻia a hiki ke hoʻokō ʻia i ka hana lua e like me ke kala a me ka sila.
