Ua ʻike anei ʻoe i kekahi mea ma ka ʻili o ka metala he ʻalani-ʻeleʻele?Ua kapa ʻia ʻo ia ʻo ka ʻōpala, ʻo ia ka ʻenemi ʻino loa o ka metala, a me nā hopena mai ka hopena o nā molekole metala ferrous me ka wai.ʻO ka Rust ke kumu o ka hoʻohaʻahaʻa ʻana i nā mea a me ka hopena i ka hāʻule ʻole o nā huahana a me nā ʻāpana mechanical.Hoʻopalapala Zinchoʻohana ʻia no ka hoʻoponopono ʻana i ka pilikia o ka hoʻokumu ʻana i ka ʻōpala ma o ka hana ʻana i kahi pale lahilahi ma luna o ka ʻili, e pale ana mai ka ʻino ʻana i ka wā e hana ai me ke kaiapuni.

Ma kēia ʻatikala, e hele mākouka hana o ka zinc plating, nā ʻanuʻu e pili ana, e pili ana i nā kumu kumu, nā pono, a me nā palena.

He aha ka Zinc Plating?

ʻO kahi ʻano hoʻopau ʻili no nā ʻāpana ferrous a me nā huahana ʻo ka zinc plating.Hoʻopili ia i ka hoʻohui ʻana i kahi ʻāpana lahilahi i ka ʻili me ka ʻole o ka hoʻohaumia ʻana i ke kūpaʻa o ka dimensional, me ka waiho ʻana i kahi ʻeleʻele ʻeleʻele hina.Hāʻawi ka Zinc plating i kahi hoʻopiʻi aesthetic maikaʻi loa i nā huahana, akā ʻoi aku ma mua o kēlā, hana ia i nā huahana corrosion resistive.Hoʻokumu ke kaʻina hana zinc plating i kahi uhi pale lahilahi ma o ka electrodepositing zinc ma luna o ka metala e uhi ʻia, i ʻōlelo ʻia ʻo ia ka mea substrate.

Pehea ka hana ʻana o ka hoʻoheheʻe Zinc?

Ke hōʻike ʻia ka zinc plating i ka ea, hana ia me ka oxygen e like me nā metala ferrous a hana i ka zinc oxide (ZnO), a laila hui pū me ka wai e hana i ka zinc hydroxide (ZnoH).

Hiki mai ka wili i kēia manawa i ka hui ʻana o ka carbon dioxide a me ka zinc oxide e hana i kahi ʻāpana lahilahi o ka zinc carbonate (ZnCO3) e pili ana i ka zinc lalo a pale hou iā ia mai ka ʻino.

Nā ʻanuʻu i komo i ka Zinc Plating

1.          Ka hoʻomaʻemaʻe ʻana i ka ʻili

ʻO ka hana mua o ka zinc plating ʻo ka hoʻomaʻemaʻe ʻana i ka ʻili e hoʻopaʻa ʻia e wehe i ka lepo, ka aila, a me ka ʻōpala i uhi ʻia me ka zinc me ka maikaʻi.No ka hoʻomaʻemaʻe ʻana, ʻo ka alkaline detergent ka mea maikaʻi loa e hoʻohaʻahaʻa ʻole i ka ʻili.Eia nō naʻe, hiki ke hoʻohana ʻia ka hoʻomaʻemaʻe ʻakika ma mua o ka hoʻohana ʻana i nā detergent alkaline.

ʻO ka ʻauʻau ma waena o 100 a me 180 degere C e kōkua i ka wehe ʻana i ka lepo ma mua o ka hoʻohana ʻana i kahi mea holoi alkaline no ka hoʻomaʻemaʻe micro-level.Ma hope o ka hoʻomaʻemaʻe ʻana me kahi mea holoi alkaline, e holoi koke i ka wahi me ka wai hoʻomaʻemaʻe e pale aku i ka pōʻino o ka ʻili mua o ka mea, hiki ke hōʻino ʻia i nā hopena alkaline.Inā ʻaʻole i hoʻokō pono ʻia ka hoʻomaʻemaʻe ʻana i ka ʻili, hiki iā ia ke kumu i ka ʻili a i ʻole ka pohō o ka uhi Zinc.

2.          Pickling

Nui nā oxides, me ka ʻōpala i hana mua ʻia, aia paha ma ka ʻili.No laila, he mea koʻikoʻi ka hoʻohana ʻana i nā ʻakika e wehe i kēia mau oxides a me nā unahi ma mua o ka hoʻomau ʻana me ka plating zinc.ʻO nā haʻina maʻamau ʻelua i hoʻohana ʻia i kēia kaʻina hana he sulfuric a me ka waika hydrochloric.Hoʻokomo ʻia nā huahana i loko o kēia hāʻina waikawa.ʻO ka manawa hoʻoluu, ka mahana, a me ka hoʻopaʻa ʻana o nā waikawa e pili ana i ke ʻano metala a me ka mānoanoa o ka unahi.

Ma hope o ka pilahi ʻana ma ke kaomi ʻana i nā ʻāpana i loko o ka wai ʻawaʻawa, e hoʻomaʻemaʻe koke me ka wai hoʻomaʻemaʻe e pale aku i nā hopena ʻino a hoʻohaʻahaʻa i ka ʻili.

3.          Ka hoʻomākaukau ʻana i ka ʻauʻau ʻauʻau

ʻO ka hana aʻe e hoʻomākaukau ana i ka hopena electrolytic no ke kaʻina hana electroplating, i ʻike ʻia hoʻi he ʻauʻau plating.ʻO ka ʻauʻau kahi solution zinc ionic e kōkua i ka hoʻomaʻamaʻa ʻana i nā kaʻina hana plating.Hiki iā ia ke zinc acid a i ʻole ka zinc alkaline;

Zink acid: ʻO ka maikaʻi kiʻekiʻe, ka hoʻopaʻa wikiwiki, ka mana uhi maikaʻi, akā maikaʻi ʻole ka mana hoʻolei a me ka hāʻawi ʻana i ka mānoanoa nāwaliwali.

ʻO ka zinc alkali:ʻO ka hāʻawi ʻana i ka mānoanoa maikaʻi me ka mana hoʻolei ʻoi aku ka maikaʻi, akā ʻoi aku ka maikaʻi o ka plating, haʻahaʻa haʻahaʻa electro-deposition rate,

4.          Hoʻonohonoho Electrolysis & Hoʻolauna i kēia manawa

ʻO ka hoʻonohonoho ʻana i ka zinc-plating

Hoʻomaka ke kaʻina hana deposition maoli me ka hoʻokomo ʻana i ka uila uila (DC) ma hope o ke koho ʻana i ka electrolyte ma muli o nā koi huahana a me nā kikoʻī.Hana ʻo Zinc ma ke ʻano he anode a ua hui pū ʻia me ka pahu ʻino ʻole o ka substrate (cathode).Hoʻopili ʻia nā iona Zinc i ka cathode (Substrate) i ke kahe ʻana o ke au uila ma o nā electrolytes, e hana ana i kahi ʻāpana pale lahilahi o ka zinc ma ka ʻili.

Eia kekahi, ʻelua mau ala no ka electrolysis: rack plating a me barrel plating (Rack & Barrel plating).

·   Nā lāʻau:Hoʻokomo ʻia ka substrate i loko o ka electrolyte i ka wā i hoʻopili ʻia i ka pahu, kūpono no nā ʻāpana nui

·   Barela:Hoʻokomo ʻia ka substrate i loko o ka barela a laila hoʻololi ʻia e loaʻa i kahi pāpale like.

5.          Mahope o ka hana ana

No ka hoʻopau ʻana i nā mea ʻino ma luna o ka ʻili, pono e hoʻomaʻemaʻe ʻia nā ʻāpana me ka wai distilled i nā manawa he nui ma hope o ka pau ʻana o ka plating.Ma mua o ka hoʻouna ʻana i nā huahana plated no ka mālama ʻana ma hope o ka holoi ʻana, pono lākou e maloʻo.Inā pono, hiki ke hoʻohana ʻia nā passivates a me nā sealants e pili ana i nā kūlana i koi ʻia no ka hoʻopau ʻana i ka ʻili.

Nā mea e noʻonoʻo ai

ʻO ka ʻike ʻana i ke kumu e kōkua i ka hoʻoponopono ʻana i ke kaʻina hana a loaʻa ka plating maikaʻi loa.Nui nā mea e pili ana i ka hopena o ka hoʻopaʻa ʻana i ka substrate.

1.          ʻAno nui o kēia manawa

ʻO ka mānoanoa o ka zinc layer, pono e waiho ʻia ma ka ʻili o ka substrate, e hoʻopili ʻia e ka nui o ke kahe o kēia manawa i nā electrodes.No laila, e hana ʻo Higher Current i kahi ʻāpana mānoanoa aʻo kahi ʻau haʻahaʻa e hana i kahi ʻāpana lahilahi.

2.          ʻO ka mahana o kahi ʻauʻau ʻauʻau

ʻO kekahi mea ʻē aʻe e hoʻopili ai i ka zinc plating ʻo ia ka mahana o ka hopena electrolysis ( Plating bath).Inā ʻoi aku ka kiʻekiʻe o ka cathode, ʻoi aku ka liʻiliʻi o nā ion hydrogen mai ka hoʻonā ʻana a i ka manawa like e lawe i nā mea hoʻomālamalama hou aʻe i ʻoi aku ka mālamalama o ka plating zinc ma muli o ke kiʻekiʻe o ka hoʻopaʻa ʻana o ke aniani metala o ka zinc.

3.          ʻO ka hoʻopaʻa ʻana o ka zinc i ka ʻauʻau plating

Hoʻopili pū ka manaʻo zinc i ka ʻauʻau ʻauʻau i ke ʻano a me ka pae o ka ʻōlinolino.ʻO kahi laʻana, ʻo ka ʻili o ka ʻili e loaʻa mai ka ʻike kiʻekiʻe no ka mea e puʻunaue like ʻole ʻia nā ion zinc a waiho koke.Ma ka ʻaoʻao ʻē aʻe, ʻo ka haʻahaʻa haʻahaʻa e hopena i ka hoʻoheheʻe ʻana no ka mea e waiho mālie ʻia nā kristal maikaʻi.

ʻO nā kumu ʻē aʻe kekahike kūlana o nā Electrodes (anode & cathode), ka maikaʻi o ka ili o ka substrate, ka Concentration o nā surfactants a me nā mea hoʻomālamalama i ka ʻauʻau plating, nā mea ʻino., a oi aku.

Nā pono

Ma waho aʻe o ka pale ʻana i ka ʻōpala, he mau pono ʻē aʻe ka zinc plating;e hele kāua i kekahi me ka wehewehe pōkole.

·        Kumukuai haʻahaʻa:ʻO ia ke ʻano kumu kūʻai kūpono o ka hoʻopau ʻana i ka ʻili i hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe, me ka uhi ʻana i ka pauka, ka hoʻopau ʻana i ka ʻeleʻele ʻeleʻele, a me ka uhi kālā.

·        E hooikaika:ʻO ka uhi zinc ma luna o nā metala ferrous, keleawe, keleawe, a me nā substrates ʻē aʻe e kōkua i ka hoʻonui ʻana i ka ikaika o ia mau mea.

·     Paʻa manaʻo:ʻAʻole pili ka hoʻohui ʻana i kahi papa zinc i ke kūpaʻa o nā ʻāpana a i ʻole nā ​​huahana,

·        ʻO ka nani nani:Ma hope o ka hoʻopaʻa ʻana, e ʻike ʻia ka ʻili o ka substrate i ka nani a me ka hoihoi, a hiki ke hoʻohui ʻia nā kala ma hope o ka hana ʻana.

·        ʻoluʻolu:No ka mea he metala ductile ka zinc, ua maʻalahi ka hana ʻana i ka substrate lalo.

Hiki ke hoʻopili wale ʻia ka zinc plating ma luna o nā metala ferrous a me nā alloys?

ʻAʻole, pili ʻo Zinc plating no nā mea ʻoi aku ma mua o nā metala ferrous a me nā alloys e like me ke keleawe a me ke keleawe.

He aha nā mea e pili ana i ke kaʻina hana zinc plating?

Hoʻopili kekahi mau mea i nā hopena o ka hoʻoheheʻe zinc, e like me ka nui o kēia manawa, ka ʻike zinc ma ka ʻauʻau plating, ka mahana, nā kūlana electrode, a me nā mea hou aku.

He aha nā ʻanuʻu e pili ana i ka hoʻopaʻa ʻana i ka zinc?

ʻO ka hoʻomaʻemaʻe ʻana i nā huahana, pickling, hoʻomākaukau ʻana i ka ʻauʻau plating, electrolysis, a me ka hoʻomaʻamaʻa hope ʻana nā mea nui i komo i ka Zinc plating.

Ua like ka galvanization me ka Zinc-electroplating?

ʻAʻole, waiho ʻia ka zinc ma ka ʻili i ka galvanization ma ke kaomi ʻana iā ia i loko o ka solution zinc.ʻOiai e hoʻohana ana ka electroplating i kahi kaʻina hana electrolysis.
