ʻO ke kālā Sterling Maʻemaʻe AgCu7.5 Enamelled/Varnished Uea no ka noi ʻana i nā huila kaʻa.

1. Mea hoʻolauna

Kālā kalahe mea kemika me ka hoailonaAga me ka helu atomika 47. He metala hoʻololi palupalu, keʻokeʻo, alohilohi, e hōʻike ana ia i ka hoʻoili uila kiʻekiʻe loa, ka hoʻoheheʻe wela, a me ka noʻonoʻo o kekahi metala. Loaʻa ka metala i loko o ka ʻāʻī o ka Honua ma ke ʻano maʻemaʻe, manuahi ʻole ("ke kālā maoli"), ma ke ʻano he huila me ke gula a me nā metala ʻē aʻe, a me nā minelala e like me ka argentite a me ka chlorargyrite. Hana ʻia ka hapa nui o ke kālā ma ke ʻano he keleawe, ke gula, ke kēpau, a me ka hoʻomaʻemaʻe zinc.

Ua waiwai nui ke kala ma ke ʻano he metala makamae. Hoʻohana ʻia ka metala kālā i nā ʻāpana bullion he nui, i kekahi manawa me ke gula: ʻoiai ʻoi aku ka nui ma mua o ke gula, ʻoi aku ka liʻiliʻi ma ke ʻano he metala maoli. Hoʻomaʻemaʻe ʻia kona maʻemaʻe ma ke kumu pākahi; he 94%-maʻemaʻe huila ua wehewehe ʻia ʻo "0.940 maikaʻi". Ma keʻano he hoʻokahi o nā metala ʻehiku o ka wā kahiko, ua paʻa ke kālā i ka hapa nui o nā moʻomeheu kanaka.

Ma waho aʻe o ke kālā a ma ke ʻano he mea hoʻopukapuka kālā (ke kālā a me ka bullion), hoʻohana ʻia ke kālā i nā panela solar, kānana wai, nā mea nani, nā mea hoʻonaninani, nā papa ʻaina kiʻekiʻe a me nā mea hana (no laila ka huaʻōlelo kālā), i nā pilina uila a me nā alakaʻi, i nā loea kūikawā. nā aniani, nā pani pukaaniani, i ka catalysis o nā hopena kemika, ma ke ʻano he kala i loko o ke aniani ʻeleʻele a me nā mea ʻono kūikawā. Hoʻohana ʻia kona mau pūhui i ke kiʻi kiʻi a me ke kiʻi X-ray. Hoʻohana ʻia nā ʻoluʻolu hoʻoheheʻe o ka nitrate kālā a me nā pūhui kālā ʻē aʻe e like me nā disinfectants a me nā microbiocides (oligodynamic effect), i hoʻohui ʻia i nā kāʻei a me nā ʻaʻahu ʻeha, nā catheters, a me nā mea lapaʻau ʻē aʻe.

Nā ʻāpana Kemika a me nā ʻano Mechanical:

2. Ka wehewehe ʻana

Hiki ke hana i ka uwea magnet insulated polyimide a hiki i 250 °C. Hoʻonui pinepine ʻia ka insulation o ka uea mānoanoa mānoanoa a i ʻole rectangular ma ke kāʻei ʻana iā ia me kahi polyimide kiʻekiʻe a i ʻole fiberglass tape, a hoʻopau pinepine ʻia nā windings i hoʻopiha ʻia me kahi varnish insulating e hoʻomaikaʻi i ka ikaika insulation a me ka hilinaʻi lōʻihi o ka wili.

Hoʻopili ʻia nā ʻōwili kākoʻo ponoʻī me ka uwea i uhi ʻia me ʻelua mau papa, ʻo ka ʻaoʻao loa he thermoplastic e hoʻopaʻa i nā huli i ka wā i wela ai.

ʻO nā ʻano ʻokoʻa ʻē aʻe e like me ka fiberglass yarn me ka varnish, pepa aramid, kraft papaer, mica, a mepoliesterHoʻohana nui ʻia ke kiʻiʻoniʻoni a puni ka honua no nā noi like ʻole e like me nā transformers a me nā reactors. Ma ka ʻāpana leo, hiki ke loaʻa kahi uea i hana ʻia i ke kālā, a me nā insulators ʻē aʻe, e like me ka pulupulu (i hoʻopaʻa ʻia me kekahi ʻano coagulating agent/thickener, e like me ka beeswax) a me ka polytetrafluoroethylene (PTFE). He pulupulu, pepa, a siliki paha na mea insulation kahiko, aka, he mea pono wale no keia no na mea wela haahaa (a hiki i 105°C).

No ka maʻalahi o ka hana ʻana, aia kekahi uea magnet haʻahaʻa haʻahaʻa haʻahaʻa i hiki ke wehe ʻia e ka wela o ka soldering. 'O ia ho'i, hiki ke hana 'ia nā pili uila ma nā wēlau me ka wehe 'ole 'ana i ka insulation ma mua.
