ʻāpana i uhi ʻia metala

ʻO kaka uhi metalaʻO ke kaʻina hana o ka uhi ʻana i kahi ʻāpana me kahi ʻāpana o nā metala a me nā ʻāpana e pale aku ai i ka pala.Ma waho aʻe o ka pale ʻana i ka pōʻino, hoʻomaikaʻi ka ʻili metala i nā ʻano mechanical, physical, aesthetic o nā ʻāpana i hoʻopili ʻia (Substrate).Nui nā ala e hoʻokō ai i ka ʻili metala ma ka ʻili, me ka electrochemically, chemically, a me ka mechanically.

ʻO Zinc, cadmium, aluminika, chrome, nickel, a me ke kālā he mau metala maʻamau i hoʻohana ʻia no ka uhi ʻana i ka Metallic.Eia naʻe, ʻo Zinc ka mea maʻamau i ka hana o ka ʻoihana hana.

E noʻonoʻo kēia ʻatikala i nā ʻenehana hoʻoheheʻe metala he nui, meelectroplating, galvanizing, powder coating, thermal spraying, pena, a me ke kila paakiki, a me ko lakou mau pono.

Nā ʻano maʻamau o ka uhi metala

1.          Electroplating

ʻO ka electroplating ke kaʻina hana o ka hoʻomohala ʻana i kahi ʻāpana lahilahi o ka metala i uhi ʻia ma ka ʻili substrate ma o ka electrolysis.Hoʻohana ʻia ka mea substrate ma ke ʻano he cathode, a ʻo ka mea uhi e like me ka anode i ka hana.Hoʻohana ʻia nā wai wai o nā ʻakika, nā kumu, a i ʻole nā ​​paʻakai e hoʻokele i ke au.Maʻaneʻi, pono e hoʻokomoʻia ka mea i uhiʻia i loko o ka wai.

Hele nā ​​ion o ka mea uhi i ka cathode i ka hoʻohana ʻana i ka uila i nā electrodes, kahi e waiho ai i kahi papa.Hoʻohana pinepine ʻia kēia ʻano hana mahoʻopalapala Zincma ka mea hao.

Hoʻonohonoho electroplating

Pono e uhi ʻia ka ʻili me ka mea i hoʻokuʻu ʻia mai ka anode.Hoʻopili ʻia ka leo deposition e kekahi mau ʻano like ʻole, me ka nui o kēia manawa, ka lōʻihi o ka electrolysis, a me nā ʻāpana ʻē aʻe.E noʻonoʻo kākou i kēia me ka hoʻohana ʻana i ka hoʻohālikelike paʻakikī.

Ka nui o ka metala i uhiia (V) = KI t

Aia i hea,

K = electrochemical equivalent mau, e like me ka electrodes a me ke ano electrolyte

I = ke au i hele ma ka electrolysis (A)

t= manawa o ka electrolysis (sec)

No ka uhi ʻana i ka maikaʻi, pono e hoʻomaʻemaʻe pono ka substrate e wehe i ka ʻōpala, nā aila, nā palaka, a me nā hemahema ʻē aʻe ma mua o ka hoʻomaka ʻana me ka electroplating.

2.          Galvanization

Nā ʻāpana galvanized

ʻO ia ke kaʻina hana hoʻoheheʻe metala maʻamau kahi i uhi ʻia ai ʻo Zinc ma ke kila a i ʻole ka hao e pale ai mai ka pala.Inā ua ʻike mua ʻoe i nā mea kila a pau he aniani kala ʻālohilohi ma luna o ko lākou ʻili, ua hoʻokumu ʻia kēlā kala ma ke galvanization a ʻike ʻia ʻo ia he kila galvanized.Hoʻopili ʻia nā ʻāpana ma ka hoʻokomo ʻia ʻana i loko o kahi hopena zinc wela, kahi e hana ai i kahi pale pale lahilahi.

I ke kaʻina hana o ka hoʻoheheʻe wela, ua hoʻokomo ʻia ka metala kumu i hoʻomaʻemaʻe ʻia (ma hope o ka hiki ʻana i kahi kokoke i ka helu heheʻe o Zinc) i loko o kahi ʻauʻau zinc hoʻoheheʻe.ʻO ka hope, hoʻokumu ʻia kahi ʻāpana pale palupalu palupalu ma ka holo ʻana i nā ʻili ma o nā wili koke i ka uhi ʻana.ʻO ka uhi metala me ka galvanization kahi ʻenehana maʻalahi, maʻalahi, a wikiwiki hoʻi e hāʻawi i ke kūpaʻa corrosion kiʻekiʻe.

ʻO nā mea hana a me nā ʻāpana o nā mīkini mahiʻai, nā kaʻa, nā lako, ke kūkulu ʻana, a me nā mea ʻē aʻe he nui i lalo i ke kaʻina galvanization.

3.          Ka uhi pauda

ʻO kauhi paudaKe hoʻohana nei ke ala i ka ikaika electrostatic e hoʻopili i kahi uhi maloʻo metala i ka ʻili o ka mea.Aia i loko o ka pauka nā ʻāpana puaʻa i hoʻomaʻemaʻe ʻia e hāʻawi i ka ʻili i kahi kala kūpono.

Hoʻomaʻemaʻe ʻia ka ʻili o ka mea e uhi ʻia i ka pae mua, kahi e hoʻoneʻe ʻia ai ka lepo, ka ʻōpala, nā palaka, a me nā mea haumia ʻē aʻe me ka hoʻohana ʻana i ka wai hoʻomaʻemaʻe a i ʻole ka wai hoʻomaʻemaʻe wale nō, e pili ana i ka hoʻomaʻemaʻe ʻana o ka ʻili a me ka hoʻopau ʻana i nā koi maikaʻi.ʻO ke kaʻina hana hoʻomaʻemaʻe hoʻi e hoʻonui i ka adhesiveness o ka ʻili i mea e ʻoi aku ka maikaʻi o ka uhi.

ʻāpana i uhi ʻia i ka pauda

Ma muli o ka hoʻohana hope ʻana, hoʻoheheʻe ʻia ka pauka ma luna o ka ʻili, a i ʻole nā ​​ʻāpana i loko o kahi wai me nā ʻāpana pauka i hoʻokuʻu ʻia.Ma hope o kēlā, hoʻomehana ʻia nā ʻāpana e hoʻoheheʻe i ka pauka a hoʻopaʻa paʻa i ka uhi.

ʻO ka hapa nui o nā lako metala he uhi pauda i hoʻohana ʻia e pale i ka hana ʻana o ka ʻōpala.ʻO ia ke ʻano kumu kūʻai ʻoi aku ka lōʻihi o nā huahana a me nā ʻāpana.

4.          Pena pena

ʻili metala i uhi ʻia i ka pena.

ʻO ka "peʻa pena metala" e pili ana i ka hoʻopili ʻana i nā pena wai like ʻole i nā ʻili.ʻO ke kaʻina hana o ka hana ʻana i kahi ʻāpana lahilahi metala ʻē aʻe e kūʻē i ka corrosion he kuʻuna loa.Eia naʻe, he mea koʻikoʻi ka hoʻokumu ʻana o ke kala i ka maikaʻi o kēia hoʻolālā.No laila, koi ʻia nā ʻano hana pena like ʻole e pili ana i ke ʻano mea, ke kaiapuni i ʻike ʻia, a me nā koi hana.

ʻAʻole lōʻihi ka lōʻihi o ka ʻili pena ma mua o nā ʻano hana hoʻoheheʻe metala ʻē aʻe a mākou i nānā ai no ka mea e pau ana ia ma hope o kekahi manawa.Eia nō naʻe, he ala maikaʻi loa ia e hana ai i nā huahana a me nā ʻāpana e hoʻokomo ʻia i loko o ka hale i ka corrosion-resistant.

5.          Hoʻopā wela

ʻO ka mea hoʻoheheʻe wela ka mea kaulana loa no ka papa metala o nā hale kila.ʻO ke kila i hoʻohana ʻia i nā ʻōnaehana liʻiliʻi a me nā ʻōnaehana nui e like me nā kaʻaahi, nā alahele, a me nā hale kila e ʻike ʻia i ke kaiapuni a pono i ka pale ikaika mai ka hoʻokumu ʻana i ka ʻōpala.Ma muli o ko lākou nui, paʻakikī kēia mau hale i ka galvanize, electroplate, a i ʻole ke kapa me nā metala pale ma o nā ala ʻē aʻe.Akā me ka hoʻohana ʻana i kahi ʻenehana hoʻoheheʻe wela, hiki ke hoʻopaʻa ʻia i nā ʻili kila me ka Zinc, aluminika, a i ʻole zinc-aluminum alloys.

Hana ʻana i ka wela wela

Hana ʻia ka hoʻomaʻemaʻe ʻana i ka hana mua e hoʻomaikaʻi i ka hoʻopili ʻana o ka ʻili a wehe i nā hemahema o ka ʻili.A laila, hānai ʻia ka pū puhi me ke kumu wela (oxygen gas flame a i ʻole uila arc) me ka pauda metala a i ʻole nā ​​ʻano uea.A laila e hoʻoheheʻe ʻia ka wai Zinc a i ʻole alumini ma ka ʻili me ka hoʻohana ʻana i ka ea compressed air jet.Hiki ke hoʻohana pinepine ʻia ka alumini ma ke ʻano he papa pale ma mua o ka Zinc e hoʻomaikaʻi i ka maikaʻi o ka uhi.Hoʻohana ia i nā oxides o titanium, chromium, a me nickel.

I kēia manawa, e kamaʻilio hou aʻe e pili ana i ka ʻili metala ma ke kila ʻoiai ka hapa nui o nā hale i kēia lā i hana ʻia me ke kila, a ʻo nā ʻano ʻoihana like ʻole e hoʻohana i nā huahana a me nā ʻāpana i hana ʻia.

ʻAi Paʻa Paʻa Paʻa

ʻO ka pahuhopu nui o ka uhi paʻakikī no ke kila, ʻo ia ka hoʻomaikaʻi ʻana i kona kūpaʻa ʻana a me ka ikaika i loko o ka mīkini hoʻoheheʻe i hiki ke pale maʻalahi i nā kaiapuni ʻoi loa me ka ʻole o ka pōʻino.

Nā ʻāpana me ka ʻili kila paʻakikī

ʻO nā mīkini he nui, me ka hydraulics, lifting, a me hydrophilic, e hilinaʻi i ka hoʻomau mau ʻana o nā ʻili;inā ʻili ʻia ka uhi ʻana, nalowale nā ​​​​ʻili i ko lākou hiki ke pale aku i ka corrosion, kahi e hāʻule ai ka mīkini.No laila, hiki i ka uhi ikaika ke hoʻomanawanui i ka holoi ʻana a paheʻe me ka ʻole o ka ʻili ʻana i ka papa i uhi ʻia.

Nā pono

·   ʻO ka hoʻopili ʻana i kahi ʻāpana metala pale i ka ʻili e pale i ka mea mai ka pōʻino a me ka ʻaʻahu.

·   Ma hope o ka hoʻopili ʻana i ka uhi metala, e pale aku ia i ka ʻaʻahu a me ka waimaka, e ʻoi aku ka lōʻihi o ka huahana hope.

·   Kōkua pū ka papa ʻokoʻa me nā ʻano mechanical a me ke kino o ka mea substrate, e like me ka paʻakikī a me ka ikaika.

·   Ua lohe paha ʻoe i ka huaʻōlelo"ka hoʻomaʻemaʻe metala"?Hōʻike ia i ka mālama ʻana i ka maʻemaʻe o ka ʻili no ka manawa lōʻihi.ʻO ka ʻili me ka uhi Metallic e pale i ka hoʻokumu ʻana o ka lepo i loko a mālama i ka maʻemaʻe.

·   Ma hope o ka uhi ʻia ʻana o ka metala, ʻike ʻia ka ʻili o ka substrate e ʻālohilohi a ʻoluʻolu, e maʻalahi ke kau ʻana i nā kala i ka wā o ka hoʻoponopono ʻana.
