ʻO ke kaula hao Sterling Silver AgCu7.5 Enamelled/Varnished no ka noi ʻana o ka Motor Coil

1. Hoʻolauna mea

Kālahe mea kemika me ka hōʻailonaAga me ka helu atomika 47. He metala hoʻololi palupalu, keʻokeʻo, ʻālohilohi, hōʻike ia i ka conductivity uila kiʻekiʻe loa, ka conductivity thermal, a me ka reflectivity o kekahi metala. Loaʻa ka metala i loko o ka ʻili o ka Honua ma ke ʻano elemental maʻemaʻe a manuahi ("kālā maoli"), ma ke ʻano he alloy me ke gula a me nā metala ʻē aʻe, a ma nā minelala e like me ka argentite a me ka chlorargyrite. ʻO ka hapa nui o ke kālā i hana ʻia ma ke ʻano he huahana o ke keleawe, ke gula, ke kēpau, a me ka hoʻomaʻemaʻe zinc.

Ua lōʻihi ka waiwai o ke kālā ma ke ʻano he metala makamae. Hoʻohana ʻia ka metala kālā i loko o nā ʻāpana kālā bullion he nui, i kekahi manawa me ke gula: ʻoiai ʻoi aku ka nui ma mua o ke gula, ʻoi aku ka liʻiliʻi o kona nui ma ke ʻano he metala kūloko. Hoʻohālikelike pinepine ʻia kona maʻemaʻe ma ke kumu o kēlā me kēia mille; ua wehewehe ʻia kahi metala 94%-maʻemaʻe he "0.940 fine". Ma ke ʻano he hoʻokahi o nā metala ʻehiku o ka wā kahiko, ua loaʻa i ke kālā kahi kuleana mau loa i ka hapa nui o nā moʻomeheu kanaka.

Ma waho aʻe o ke kālā a ma ke ʻano he mea hoʻopukapuka kālā (nā ʻāpana kālā a me nā bullion), hoʻohana ʻia ke kālā i nā panela solar, ka kānana wai, nā mea hoʻonani, nā mea hoʻonaninani, nā kīʻaha a me nā mea hana waiwai nui (no laila ke ʻano o ka huaʻōlelo silverware), i nā pilina uila a me nā alakaʻi, i nā aniani kūikawā, nā uhi puka makani, i ka catalysis o nā hopena kemika, ma ke ʻano he kala i loko o ke aniani i poni ʻia a me nā mea ʻono kūikawā. Hoʻohana ʻia kāna mau hui i nā kiʻi paʻi kiʻi a me nā kiʻiʻoniʻoni X-ray. Hoʻohana ʻia nā hopena dilute o ka nitrate kālā a me nā hui kālā ʻē aʻe e like me nā disinfectants a me nā microbiocides (ka hopena oligodynamic), i hoʻohui ʻia i nā bandages a me nā ʻūlū ʻeha, nā catheters, a me nā mea lapaʻau ʻē aʻe.

Nā ʻāpana kemika a me nā waiwai mīkini:

2. Wehewehe ʻana o ka pale ʻana

Hiki i ka uea makeneka polyimide insulated ke hana a hiki i ka 250 °C. Hoʻonui pinepine ʻia ka insulation o ka uea makeneka huinahā a ʻehā paha mānoanoa ma ke kāʻei ʻana me kahi polyimide wela kiʻekiʻe a i ʻole ka lipine fiberglass, a ʻo nā wili i hoʻopau ʻia e hoʻomaʻū pinepine ʻia me kahi varnish insulating e hoʻomaikaʻi i ka ikaika insulation a me ka hilinaʻi lōʻihi o ka wili.

Ua ʻōwili ʻia nā wili kākoʻo ponoʻī me ka uea i uhi ʻia me ka liʻiliʻi o ʻelua papa, ʻo ka mea waho loa he thermoplastic e hoʻopaʻa ana i nā wili i ka wā e hoʻomehana ʻia ai.

ʻO nā ʻano ʻē aʻe o ka insulation e like me ka fiberglass yarn me ka varnish, ka pepa aramid, ka kraft pepaer, mica, a mepolyesterHoʻohana nui ʻia ke kiʻiʻoniʻoni ma ka honua holoʻokoʻa no nā noi like ʻole e like me nā mea hoʻololi a me nā reactors. Ma ka ʻāpana leo, hiki ke loaʻa kahi uea o ke kūkulu kālā, a me nā mea hoʻokaʻawale ʻē aʻe, e like me ka pulupulu (i kekahi manawa i hoʻopiha ʻia me kekahi ʻano mea hoʻohuihui/mānoanoa, e like me ka beeswax) a me ka polytetrafluoroethylene (PTFE). ʻO nā mea hoʻokaʻawale kahiko e komo pū ana me ka pulupulu, ka pepa, a i ʻole ka silika, akā he mea pono wale nō kēia no nā noi haʻahaʻa haʻahaʻa (a hiki i 105°C).

No ka maʻalahi o ka hana ʻana, aia kekahi uea magnet haʻahaʻa haʻahaʻa i loaʻa ka insulation hiki ke wehe ʻia e ka wela o ke kūʻai ʻana. ʻO ke ʻano kēia, hiki ke hana ʻia nā pilina uila ma nā wēlau me ka ʻole o ka wehe ʻana i ka insulation ma mua.
