Nickel200/201 mesh uea a me nickel200/201 metala hoʻonui
He aha ka Nickel Mesh?
ʻElua ʻano ʻano ʻano nickel mesh: Nickel wire mesh a me nickel expanded metal. Hana ʻia ka uea nickel me ka ulana ʻana i ka uea nickel maʻemaʻe, hana ʻia ka metala hoʻonui ʻia ma ka hoʻonui ʻana i ka nickel foil maʻemaʻe.
| Papa | C (Kapona) | Cu (Ke keleawe) | Fe (Hao) | Mn (Manekene) | Ni (Nikela) | S (Sulphur) | Si (Silikona) |
| Nikela 200 | ≤0.15 | ≤0.25 | ≤0.40 | ≤0.35 | ≥99.0 | ≤0.01 | ≤0.35 |
| Nikela 201 | ≤0.02 | ≤0.25 | ≤0.40 | ≤0.35 | ≥99.0 | ≤0.01 | ≤0.35 |
| Nikela 200 vs 201:I ka hoʻohālikelike ʻana i ka nickel 200, ʻaneʻane like nā ʻano inoa inoa o ka nickel 201. Eia naʻe, haʻahaʻa kona ʻano kalapona. | |||||||
ʻO kekahi o nā waiwai nui a me nā hiʻohiʻona o ka nickel wire mesh maʻemaʻe:
- Kūleʻa wela kiʻekiʻe: Hiki ke kū i nā wela a hiki i ka 1200°C maʻemaʻe ka uwea nickel maʻemaʻe, e kūpono ana i nā wahi wela wela e like me nā umu ahi, nā mea hoʻokalakupua kemika, a me nā noi aerospace.
- ʻO ke kūpaʻa ʻino: He kūpaʻa loa ka mīkini uwea nickel maʻemaʻe i ka ʻino mai nā waikawa, alkalis, a me nā kemika koʻikoʻi ʻē aʻe, i mea kūpono no ka hoʻohana ʻana i nā mea kanu hana kemika, nā mea hoʻoheheʻe aila, a me nā mea kanu desalination.
- Ka lōʻihi: He ikaika a paʻa ka mīkini wili nickel maʻemaʻe, me nā waiwai mechanical maikaʻi e hoʻopaʻa i kona ʻano a hāʻawi i ka hana lōʻihi.
- ʻO ka conductivity maikaʻi: He maikaʻi ka conductivity uila nickel mesh maʻemaʻe, pono ia no nā noi i ka ʻoihana uila.
Uea nikelaa he mea koʻikoʻi nā electrodes i ka ʻoihana hana hydrogen, ʻoi aku hoʻi i nā electrolyzers. ʻO kekahi mau polokalamu koʻikoʻi:
Electrolysis: ʻO ka nickel mesh he electrode maikaʻi loa a paʻa i ka electrolysis, e hoʻomaʻamaʻa i ka hoʻokaʻawale ʻana o ka wai i ka hydrogen a me ka oxygen.
Huina wahie: Hoʻohana ʻia nā nickel electrodes i loko o nā pūnaewele wahie e catalyze hydrogen oxidation a hana i ka ikehu uila me ka hana kiʻekiʻe.
Hoʻopaʻa wai hydrogen: Hoʻohana ʻia nā mea hana nikela i loko o nā ʻōnaehana mālama hydrogen ma muli o ko lākou hiki ke komo a hoʻokuʻu i ke kinoea hydrogen me ka hoʻohuli.
