Wehewehe Huahana

Ua hoʻohana nui ʻia kēia mau uea kū'ē enameled no nā resistors maʻamau, nā kaʻa
nā ʻāpana, nā pale wili, a pēlā aku e hoʻohana ana i ke kaʻina hana insulation kūpono loa no kēia mau noi, e hoʻohana pono ana i nā hiʻohiʻona ʻokoʻa o ka uhi enamel.

Eia kekahi, e hoʻokō mākou i ka uhi enamel insulation o ka uea metala makamae e like me ke kālā a me ka uea platinum ma ke kauoha. E ʻoluʻolu e hoʻohana i kēia hana-ma-ke kauoha.

ʻAno o ka Uea Alloy ʻōlohelohe

ʻO ka mea hoʻohuihui hiki iā mākou ke hana i ka enamelled he uea keleawe-nickel, uea Constantan, uea Manganin. Kama Wire, uea NiCr Alloy, uea FeCrAl Alloy etc.

Nui:

Uea poepoe: 0.018mm ~ 2.5mm

Kala o ka insulation enamel: ʻUlaʻula, ʻōmaʻomaʻo, melemele, ʻeleʻele, polū, kūlohelohe etc.

Ka nui o ka lipine: 0.01mm * 0.2mm ~ 1.2mm * 5mm

Moq: 5kg no kēlā me kēia nui

Wehewehena Keleawe:

Keleawehe mea kemika me ka hōʻailonaCu(mai ka Latina mai:kupa) a me ka helu atomika 29. He metala palupalu, malleable, a ductile me ke alakaʻi wela a me ka uila kiʻekiʻe loa. He ʻulaʻula-ʻalani ke kala o kahi ʻili keleawe maʻemaʻe i hōʻike hou ʻia. Hoʻohana ʻia ke keleawe ma ke ʻano he alakaʻi o ka wela a me ka uila, ma ke ʻano he mea kūkulu hale, a ma ke ʻano he ʻāpana o nā metala like ʻole, e like me ke kālā sterling i hoʻohana ʻia i nā mea hoʻonani, cupronickel i hoʻohana ʻia e hana i nā lako a me nā kālā moana, a me ka constantan i hoʻohana ʻia i nā ana hoʻohihi a me nā thermocouples no ke ana ʻana i ka mahana.

ʻO ke keleawe kekahi o nā metala kakaikahi e hiki ke loaʻa ma ke ʻano maoli ma ke ʻano metala hiki ke hoʻohana pololei ʻia (nā metala maoli). Ua alakaʻi kēia i ka hoʻohana mua ʻana o ke kanaka ma kekahi mau wahi, mai ka makahiki 8000 BC. He mau tausani makahiki ma hope mai, ʻo ia ka metala mua i hoʻoheheʻe ʻia mai nā ores sulfide, ma ka makahiki 5000 BC, ka metala mua i hoʻolei ʻia i loko o kahi ʻano i loko o kahi mold, ma ka makahiki 4000 BC a me ka metala mua i hoʻohuihui ʻia me kekahi metala ʻē aʻe, ka tin, e hana i ke keleawe, 3500 BC.

ʻO nā hui i loaʻa pinepine ʻia he mau paʻakai keleawe (II), ka mea e hāʻawi pinepine i nā kala polū a ʻōmaʻomaʻo paha i nā minelala e like me ke azurite, malachite, a me ka turquoise, a ua hoʻohana nui ʻia a me ka mōʻaukala e like me nā pigments.

ʻO ke keleawe i hoʻohana ʻia i nā hale, ʻo ia hoʻi no ka uhi ʻana o ka hale, hoʻopau ʻia e hana i kahi verdigris ʻōmaʻomaʻo (a i ʻole patina). Hoʻohana ʻia ke keleawe i kekahi manawa i nā hana hoʻonaninani, ma kona ʻano metala kumu a me nā hui e like me nā pigments. Hoʻohana ʻia nā hui keleawe ma ke ʻano he mau mea bacteriostatic, fungicides, a me nā mea mālama lāʻau.

He mea nui ke keleawe i nā meaola ola a pau ma ke ʻano he mineral meaʻai liʻiliʻi no ka mea he ʻāpana koʻikoʻi ia o ka hui enzyme hanu cytochrome c oxidase. I loko o nā molluscs a me nā crustaceans, ʻo ke keleawe kahi ʻāpana o ka pigment koko hemocyanin, i pani ʻia e ka hemoglobin i hoʻopili ʻia me ka hao i loko o nā iʻa a me nā vertebrates ʻē aʻe. I loko o ke kanaka, loaʻa nui ke keleawe i loko o ke akepaʻa, nā ʻiʻo, a me ka iwi. Loaʻa i ke kino makua ma waena o 1.4 a me 2.1 mg o ke keleawe no kēlā me kēia kilokani o ke kaumaha o ke kino.
