Hoʻohou hope:09/02, manawa e heluhelu ai: 7mins

Nā ʻāpana alumini anodized me nā kala like ʻole

Ma muli o ko lākou māmā a me ka ikaika kiʻekiʻe,aluminika a me kona mau helu like ʻole o nā alloyshoʻohana pinepine ʻia nā mea kūkulu hale i nā ʻoihana like ʻole, me ka lāʻau lapaʻau, automotive, a me ka aerospace.ʻAʻole pili i ke kaʻina hana i hoʻohana ʻia e hana i kēia mau ʻāpana.Hoʻopau ʻilihe mea nui ia e hoʻonui i kēia mau ʻāpana 'mea hana a me ka nani nani.

No ka mea hiki ke uhi ʻia ka laulā o nā kala ma ka ʻilianodizing, ʻo ia ke ʻano hana hoʻopau honua kaulana loa i hoʻohana ʻia i ka hana honua.Hana ʻia nā ʻāpana alumini i mea kūpaʻa a maikaʻi loa e kūʻē i ka ʻike ʻana i ke kaiapuni, mahalo i ke kala anodizing.Eia kekahi, hiki ke hoʻokō ʻia ka hiki ke pale i ka abrasion ma ke kala anodizing.E nānā kēia ʻatikalake kaʻina hana anodizing Aluminum, nā ʻano kala like ʻole, ka hoʻohālikelike kala, a me nā kaʻina pili.

Kaʻina Anodizing Aluminum

ʻO ka hoʻomaʻemaʻe ʻana i nā ʻāpana i hana ʻia ʻo ia ka hana mua i ka anodizing aluminika, a ʻo ke kahakaha ʻana i ka alkaline ka mea hoʻomaʻemaʻe maikaʻi loa no ka hana.Hoʻopau ʻia nā aila māmā a me nā mea ʻē aʻe e hoʻopilikia i ke kaʻina hana anodizing i kēia kaʻina hoʻomaʻemaʻe.Pono e hana ʻia ka ʻili alkali ma hope o ka hoʻomaʻemaʻe ʻana i mea e hoʻopau ai i nā oxide kūlohelohe i koe mai ka ʻili.ʻO ka koho maikaʻi loa no ia mea he sodium hydroxides.

ʻO ka hana aʻe, ʻo ia ke kipaku ʻana i nā ʻāpana alumini i hoʻomaʻemaʻe ʻia a i kālai ʻia i loko o kahi hopena nitric acid e hoʻomaʻamaʻa i ka ʻili a hoʻomākaukau no ka anodizing.

ʻO nā ʻanuʻu like ʻole no ka kala kala anodized alumini

ʻO ka hope, hoʻokomo ʻia nā ʻāpana alumini i kahi electrolyte o ka sulfuric acid no ka anodizing.Aia ka Cathode ma waho o ka pahu electrolyte.ʻO nā ʻāpana alumini e pono e uhi ʻia e lilo i anode.A laila, hoʻopili ʻia kahi ʻāwī uila i ka electrode ("+" terminal i ka anode a me "-" terminal i Cathode).I kēia manawa, neʻe ka uila uila ma o ka hopena electrolytic a hoʻokuʻu i nā ion oxide, e hele ana i ka substrate alumini e hana i ka papa oxide i hoʻohui ʻia ma ka ʻili.

Nā kala ma nā ʻāpana anodized alumini

ʻO ka mea maʻamau, ua kala ʻia nā ʻāpana alumini anodized me ka hoʻohana ʻana i nā ʻano ʻehā: ke kala ʻana, ke kala kala, ka kala electro, a me ka kala hoʻohui.E nānā pono kākou i kēlā me kēia o lākou i kēia manawa.

kala uila

Hiki ke loaʻa maʻalahi nā kala like ʻole i nā ʻāpana alumini anodized me kakala electrolytic.Hoʻohana ka kala electrolytic i nā paʻakai metala like ʻole ma ke ʻano he mea kala, kahi e waiho ʻia ai nā ion metala o ka paʻakai i hoʻohana ʻia i loko o nā pores o nā ʻāpana alumini anodized.No laila, pili ke kala i ka metala i hoʻohana ʻia i ka wai paʻakai.

Kaʻina kala kala uila

Ma ke ʻano o ke kaʻina hana electrolysis, hoʻoheheʻe ʻia ka ʻili anodized i loko o nā ʻoluʻolu paʻa o nā paʻakai metala a hiki i ka lawa ʻana o ka puaʻa e hana i ke kala i makemake ʻia.No laila, pili ka waihoʻoluʻu i ka metala i hoʻohana ʻia i ka paʻakai, a ʻo ka ikaika o ke kala e pili ana i ka manawa o ka mālama ʻana (30 kekona a 20 mau minuke).

Hoʻohana ʻia kekahi mau paʻakai metala maʻamau i ka kala alumini anodized 

kala kala

ʻO kahi ala ʻē aʻe e kala ai i ka ʻāpana alumini anodized he kala kala.ʻO kēia kaʻina hana e komo wale i nā ʻāpana e kala ʻia i loko o ka pahu i loaʻa ka wai wai.ʻO ka ikaika o ka waihoʻoluʻu ma kēia ala e pili ana i nā ʻokoʻa like ʻole e like me ke ʻano o ke kala, ka manawa mālama, a me ka mahana.

Nā kikoʻī no ka kala kala:

Nā ʻōlelo aʻoaʻo no ke kala kala maikaʻi

·        He mea koʻikoʻi ka hoʻomaʻemaʻe ʻana i nā ʻāpana alumini anodized no ka mea hiki ke hoʻopilikia ʻia nā waika lōʻihi ma ka ʻili i ke kaʻina make.I kekahi mau kūlana, ʻo ka loaʻa ʻana o nā ʻakika e pale i ka alumini mai ka waiho ʻana.No laila, ma mua o ka hoʻomaka ʻana i ka ʻauʻau wai, e hoʻohana i ka sodium bicarbonate e desorb.

·        Pono e hoʻopau ʻia nā ʻanuʻu o ka anodizing a me ka ʻauʻau wai i ka manawa like, me nā ʻāpana e waiho ʻia i loko o ka pahu wai i ka wā e wehe ʻia ai lākou mai ka pahu anodizing.

·        Eia hou, e mālama i ka waika a i ʻole nā ​​mea ʻino ʻē aʻe mai ka pahu wai.

kalai huikau

Hoʻohui nā kaʻina hana kala ʻelua i nā ala like ʻole.ʻO ka mea mua, ua anodized nā ʻāpana alumini, a ua kala ʻia nā ʻāpana anodized me nā alloys.No laila, ʻo ka hana o kahi alloy kūikawā i kēia kaʻina hana ke ʻano o ka hoʻomohala ʻana o ke kala.Ma muli o ka hoʻohui ʻana o nā ʻāpana alumini a me nā kūlana hana, hiki ke ʻano ke kala mai ke keleawe gula ma o ke keleawe hohonu a ʻeleʻele.

Kalai hoʻohalahala

ʻO kēia ala e pili ana i ka hoʻonui ʻia ʻana o ka hana pore a me ka waiho ʻana o nā metala kūpono e pili ana i nā kala i makemake ʻia ma ka ʻili e kiʻi i ka ʻili kala.E like me ka loaʻa ʻana o kahi kala polū-hina ke waiho ʻoe i kahi nickel.ʻO ke kumu, hoʻopuka ʻia nā waihoʻoluʻu interference i ka wā e paʻi ai ka mālamalama i nā ʻili alumini anodized a hoʻohuli ʻia, ʻike ʻia, a i ʻole ʻia.

Hoʻopaʻa-Kaʻina

Kaʻina hana sila

ʻO ka pahuhopu nui o ke kaʻina hana hoʻopaʻa ʻana, ʻo ia ka hoʻōki ʻana i nā moleke makemake ʻole mai ka komo ʻana i loko o nā pores.No ka mea, mālama ʻia nā lubricants a i ʻole nā ​​molekole ʻē aʻe i makemake ʻole ʻia i loko o nā pores, i ka hopena e hāʻawi i ka pala.ʻO kekahi mau mea hoʻopaʻa maʻamau he nickel acetate, potassium dichromate, a me ka wai paila.

1.          ʻano wai wela

Hoʻohana mau ʻia ke kila kila a i ʻole kekahi mea inert e hana i ka pahu sila.Hoʻokomo mua ʻia nā ʻāpana alumini kala i loko o ka wai wela (200 0F), kahi e puka ai ka alumini monohydrate ma luna o ka ʻili, me ka hoʻonui ʻana i ka nui.ʻO ka hopena, ua hoʻopau ʻia nā molekala i makemake ʻole ʻia mai ka pore.

2.           ʻO ke ʻano o ka Nickel Fluoride

Hoʻopalupalu kēia kaʻina hana i nā mea alumini anodized.Ma kēia ʻano, hoʻokomo ʻia ka nickel fluoride i ka alumini anodized.Ke hele nei ka ion Fluoride i nā pores, kahi e hoʻoheheʻe ai ka ion nickel ma ka ʻili a hana i ka nickel hydroxide ma ka hui pū ʻana me nā molekole wai, a pale i nā pores.

3.          ʻO ke ʻano o ka Potassium Dichromate

Hoʻohana kēia ʻenehana i ka hopena potassium dichromate (5 % w/V) e hoʻopaʻa i nā ʻāpana alumini anodized.ʻO ka mea mua, hoʻokomo ʻia nā ʻāpana no kahi o 15 mau minuke i loko o kahi pahu i loaʻa kahi hopena paila o ka potassium dichromate.A laila, hoʻopili ka ʻili o nā ʻāpana i nā ion chromate, a hiki ke uhi ʻia ke hoʻoheheʻe ʻia kēia mau ion.ʻOiai ʻoi aku ka liʻiliʻi o ka ʻeleʻele ma mua o nā ʻano sealant ʻē aʻe, hāʻawi mau kēia uhi i kahi ala pololei i ke sila.

Kaulike kala

Hiki ke ʻokoʻa ka waihoʻoluʻu e like me nā ʻāpana like ʻole;akā naʻe, inā ʻoe e hahai i ke kaʻina hana kala no nā ʻāpana alumini anodized.Ma muli o kēia, ʻo ke kaʻina hana a me nā mea ʻē aʻe e like me ke ʻano o ka alumini i hoʻohana ʻia, ke ʻano o ka hoʻopau ʻana, ka neʻe ʻana o nā mea make, a me ke ʻano o ka crystalline o ka ʻili e like like me nā pūʻulu e kiʻi i ke kala like.

Ka hopena

Ma hope o ka nānā ʻana i ka anodizing a me ke kala ʻana o nā ʻāpana alumini, ua maopopo ka maikaʻi loa o ka anodizing alumini ka hiki ke hoʻokomo i nā kala like ʻole ma luna o ka ʻili, ʻaʻole ia e hoʻonui wale i nā waiwai mechanical a me ka nani nani akā e hoʻokō pū ana i ka noi mākeke.Eia kekahi, ʻo ke ʻano kala kala electro ka maikaʻi loa o nā ala ʻehā i ka kala ʻana no ka mea e waiho ana i ka kala electrochemically a hiki ke hana i kahi ākea o nā kala ma ke koho ʻana i ka wai paʻakai kūpono.

ʻO ka mea kānalua, paʻakikī loa ke kaʻina hana anodizing alumini no ka mea e pili ana i ka nui o ka kemika, ʻepekema waiwai, a me ka hana ʻenekinia.Eia naʻe, ʻaʻohe huikau inā koho ʻoe i kā mākoulawelawe anodizing. ʻO kā mākou ʻepekema waiwai a me ka ʻenehana mīkinie hāʻawi ka poʻe loea iā ʻoe me ka anodizing alumini o ka caliber kiʻekiʻe loa, a hiki iā ʻoe ke koho i ke kala i kūpono i kāu papahana.
