Ua hoʻohana nuiʻiaʻo Zinc ma waena o nāʻoihana no kona paleʻana o kāna coristion maikaʻi loa, e hana ana i kahi mea kaulana no nā lole, alloys, a me nā palapala noi.
Akā, he nīnau maʻamau pinepine: ʻO Zinc Rust? E pane i kēia, Pono mākou eʻimi i nā waiwai o Zinc, ʻO kaʻepekema ma hope o ka rust, a me ke kū'ēʻana i keʻano o kēiaʻano metala.
E nānā i kahi kokoke i ka hana a Zinc i ka wā i hōʻikeʻia ai i nā kūlana kūlohelohe a pehea e hoʻohālikelike ai i nāʻano kuʻuna.
1. He aha zinc?
ʻO Zinc kahi mea hao keʻokeʻo-keʻokeʻo me ka hōʻailona emika Zn. He mea nui loa ia i loko o ka lepo o ka honua a ua hoʻohanaʻia no nā makahiki he nui, kūikawā no Galvanizing Steel a me nā metala'ē aʻe.
Ua waiwai nuiʻo Zinc no kona mau manawa a me kona hiki ke pale aku i ka corrosione.
He mea koʻikoʻi ia ma nāʻoihana e like me ke kūkuluʻana, aitompetitive, AerERPPACE, a me na uila, kahi e kū ai ka paleʻana.
Nā kumu nui o zinc:
- Malting Point: 419.5° C (787.1° F)
- Huakai: 7.13 g / cm³
- Ke kū'ē neiʻo Corrosionion: ʻO ke kaua nui loa i ka corrosion, nui loa i loko o ka atmospheric a me nā wahi moana
- Hana elehua: ʻOi aku ka ikaika o ka electrochemically ma mua o ka hao, ʻO ia ka mea kūpono no ke kila Galvanizing
No ka mea,ʻo Zinc kūlohelohe i kahi pale pale pale i ka wā i hōʻikeʻia ai i ka lewa, He maʻamau maʻamau i loko Galvaniration, kahi e coats salal e pale aku ai iā ia mai ka rust.
ʻO kēia pale pale e pāʻani ana i kahi kūlana koʻikoʻi i ka paleʻana i ka corrosion a me ka noʻonoʻoʻana i ke ola o keʻano.
2. He aha ka mea?
'Ōwili heʻano o ka corrosio e pili ana i ka hao.
E hele ana ia i ka wā i hoʻohuli ai ka hao me ka oxygen a me ka wai, Hoʻokumu i ka or ot ot (Lihuaipuai), ʻO kahi meaʻulaʻulaʻulaʻula iʻikeʻia e like me ka rust.
'Ōlelo Ke kaʻina hana hiki ke wāwahiʻia i loko o kekahi mau mea kanu:
- 'Lelo 1: ʻO ka mea hao i loko o ka oxygen i ke alo o ka wai.
- 'Lelo 2: ʻO ka hopena e hana ai i ka hydroxide i ka hydroxide (Lia(Oh)₂).
- 'Lelo 3: ʻO ka mea haoʻo Hydroxide hou me ka oxygen e hana i ka or ot ('ōwili).
ʻO ka hopena he brittle, flaky i nā mea e nāwaliwali i ka metala, ʻaeʻia ka hoʻopaʻi e hoʻolaha a hōʻino i ka waihona kumu.
ʻAʻole like zinc, ʻAʻole hāʻawiʻo Rust i kekahi pale; ke kumu i ka holomua holomua o ka manawa.
Ka chemistry o ka holoʻana:
| Waiwai | Huahana maikaʻi | Keʻano o ke kahe |
|---|---|---|
| 'Eron | ʻO nā Olbide kala ('Ōwili) | Lia + OAHO + HONDON → FonV · NH₂O |
| Zinc | ZinC Oxide / Carbonate | Zn + O₂ / H₂o → ZNO / ZNCO₃ (Pale pale) |
3. ʻO Zinc Rust?
ʻO ka pane pōkole: ʻAʻole paʻaʻo Zinc i keʻano kuʻuna. ʻAʻole like me ka hao, ka mea i kau ai i ka hao hao ('ōwili), ʻO Zinc i hana i kahi'āpana oxide a iʻole ka carbonate i ka wā iʻikeʻia ai i ka oxygen a me ka nui.
Mālama kēia ala i ka corrosione hou, e hana ana ma waena o kahi pā ma waena o ka zinc a me ka nohona o waho.
Pehea e hana aiʻo Zinc i kāna papa pale:
I ka manawa e hana ai ka zinc me ka oxygen, he puka Zinc oxide (Zno). Ua holo ʻoi aʻe ka manawa, I mua o ke kailala dioxide, Hiki i Zinc oxide e hana i keʻano zinc carbonate (Znco₃).
ʻO kēia mau mea hoʻohuiʻelua, pale pale ma luna o kaʻili o zinc, pale aku iā ia mai ka corrosione hou.
Nā kiʻi nui:
- Zinc oxide a zinc carbonate E hana i kahi pale pale pale.
- Ke pale nei kēia mau mea i ka hoʻolahaʻana o Zinc i ka oxygen a me ka nui, Ke hooki nei i ke kaʻina hana.
- ʻO kēia ke kumu e hoʻohana pinepineʻia aiʻo Zinc no nā noi o waho e like me ke kauʻana, nā'āpana automothetive, a me nā mīkiniʻoihana.
4. Zinc Corrosion vs. Kāʻe
ʻOiaiʻo Zincʻaʻole e hele i loko o ka manaʻo maʻamau, IT hiki ke hoʻoponopono ma lalo o kekahi mau kūlana. He mea nui ia e hoʻokaʻawale i waena o nāʻano o ka corrosion e hiki ai i ka pili o Zinc a me ka hao:
Nāʻano o ka corrosio:
- Keʻokeʻo keʻokeʻo (Zinc hydroxide): Ke hōʻikeʻiaʻo Zinc i ka wai, nui loa i nā wahi kiʻekiʻe, Hiki iā ia ke hana i kahi keʻokeʻo, ʻO nā mea powdey iʻikeʻia e like me ke keʻokeʻo keʻokeʻo.
ʻo kēia Zinc hydroxide (Zn(Oh)₂), e hele ana i loko o ka pāū Oole kūlana alkalia.
ʻOi aku ka maikaʻi o ke keʻokeʻo keʻokeʻo ma mua o ka hao hao, A hiki i kona kūlana ke liʻiliʻiʻia me nā hana kūpono kūpono.
- 'Ulaʻulaʻula (ʻO nā Olbide kala): Hao hao, ma ka lima ʻē aʻe, hana i kahi flaky, ʻO nā pāpale Brittle e hoʻomau i ka hōʻinoʻana i ka metala, ka hopena pinepineʻana i ka hanaʻole.
ʻO ka hoʻohālikelikeʻana o ka corrosionion:
| Waiwai | ʻAno o ka corrosiot | ʻO ka weheweheʻana |
|---|---|---|
| Zinc | Keʻokeʻo keʻokeʻo (Zn(Oh)₂) | He pale, Ka liʻiliʻiʻana i ka huahana corrosion. Hiki ke hoʻopauʻia me nā lole. |
| 'Eron | 'Ulaʻulaʻula (Lihuaipuai) | FlaKY, nāwaliwali nāwaliwali e hoʻomau mau ana i ka waiwai. |
5. Pehea e pale aku aiʻo Zinc i kahi wikiwiki i ke kila: ʻO ka hana o Galvanization
Hiki iā Zinc ke pale aku i ka wikiwiki ka mea kaulana loa i hōʻikeʻia Galvaniration.
Hoʻopili kēia kaʻina hana i ka hoʻopiliʻana i kahi'āpana'āpana o Zinc i ke kila a i hao paha, ka hoʻolakoʻana i ka metala me ka paleʻana i ka mālama kaumaha.
Hana ka zinc ma keʻano he barrier i ka mistiture a me ka oxygen, Akāʻoi aku ka mea nui, IT Hāʻawi iho iā ia iho e pale aku i ka mea kila ma lalo.
Inā hōʻinoʻia ka pahu zinc, E mālamaʻia ka mea i hōʻikeʻia no ka meaʻo Zinc Corrodes ma mua o ka kila.
Hana iā Galvanirirition:
- Wela-dip galvalizing: Uaʻokiʻiaʻo Steel i loko o Molten Zinc, ka hoʻokumuʻana i kahi paʻa ikaika ma waena o nā meaʻelua.
- Hoʻololi: Ua hoʻopiliʻiaʻo Zinc ma o ka electrochemicalʻano, Ke hana nei i kahi'āpana, ʻO ka moe ma luna o ke kumu kila.
Nā pōmaikaʻi o Galvanizationʻo Galvaniration:
- NA MAKAWAI: Zinc corrodent mua, pale aku i ke kila.
- FILLTEDED MODESPAN: ʻO nā mea kila i hala hou loa, hōʻemi i nā uku mālama mālama.
- Durability: Hiki i nā huahana Galvanized 30-50 mau makahiki a keu paha, Ke hilinaʻi nei i nā kūlana kūlohelohe.
Mālamaʻo Galvanized:
| Kūkaha kūlana | ʻO ke olaʻana o keʻano o Zinc | Nā moʻolelo |
|---|---|---|
| Rural | 50+ mau makahiki | Ka hōʻike liʻiliʻi i nā mea hoʻohui a iʻole ka nui o ka wā. |
| Kūlanakauhale | 40-50 mau makahiki | Ka hoʻolahaʻana i ka haumia haʻahaʻa. |
| Kailoa | 20-30 mau makahiki | E hoʻopauʻo Salwater i ka ORCETRATER ZINC CORROSION. |
6. Zinc a me nā kumu kaiāulu: ʻO ka mea e pili ana i kona lōʻihi?
ʻOiaiʻo Zinc he mea hilinaʻi nui loa i ka corrosion, Hiki ke hoʻopilikiaʻia kona longogevity i nā mea kūlohelohe e like me kaulike, waiapula, a Nāʻona ai.
E nānā mākou i nā mea nui e hiki ai ke hōʻeha i ka hana o ka zinc i nā kūlana likeʻole:
- Waiapula: Hiki i nā wahi o nā kahakai a iʻole nā wahi me kaʻike kiʻekiʻe e hiki ke hoʻonui i ka hoʻokumuʻana i keʻano o ke keʻokeʻo keʻokeʻo, i loko āohiʻia zinc a iʻole nā wahi i hōʻinoʻia.
- ʻO nā wahi ACIDIC: Nā kūlana ACIDIC maikaʻi loa (e like me nā mea kanu lāʻau a iʻole ka ua acidic) hiki ke wāwahi i ka wikiwiki o ka pale o Zinc.
- Haumia: Polokalamu Polokalamu, komo me nā coulfur dioxide a me nā nitrogen, hiki ke hāʻawi i ka degradation o nā lole o Zinc.
Pale aku iā Zinc i nā wahiʻeha: E hōʻoia i ka lōʻihi o ka lōʻihi o Zinc i nā wahi paʻakikī, Nā lole pale hou, e like me pehi Oole Nā Koa Kiʻi, ua hoʻohana pinepineʻia ma luna o nā papa galvanized.
ʻO kēia pale aku i ka paleʻana i ka zinc mai kaʻikeʻana i ke kaiāulu a hoʻonui i kona ola.
7. Hopena
I ka hopena, ʻAʻole paʻaʻo Zinc i keʻano kuʻuna, Akā hiki iā ia ke pale ma waena o keʻano ma o ka hoʻokumuʻana o ke keʻokeʻo keʻokeʻo i kekahi mau kūlana.
ʻO Zinc ka pale o Zinc i ka wikiwiki a me ka corrosion kekahi o nā kumu e nui loa ai, loa ma ka Hana iā Galvanirirition, kahi e pale ai i nā kila a me nā metala'ē aʻe mai ka rust.
Hiki i ka zinc ke hana i kahi pale pale pale pale a iʻole ka carbonate e hoʻopaʻa ana i ka mea e koiʻia ai no ka nui o nā noi, mai ke kūkuluʻana i nā'āpana autoomtive.
ʻOiaiʻo Zinc ka lōʻihi o ka lōʻihi o Zinc, He mea nui ia e noʻonoʻo i nā kūlana kūlohelohe i ka wā e hoʻoholo ai i kona kūpono no nā noi kūikawā.
Me ka mālama kūpono a me ka mālamaʻana, Hiki i Zinc ke hoʻomau i ka mālamaʻana i ka paleʻokoʻa, e hōʻoia ana i ka lōʻihi o nā huahana a me nā hana ma waena o nāʻoihana likeʻole.
