0.025mm tungsten uea 99.95% maemae tungsten filament
Ma waho aʻe o ka hoʻohana ʻana i nā ʻōpuʻu kukui, ua hoʻohana nui ʻia ka uea tungsten ma ke ʻano he mea hoʻomālamalama i nā mea uila ʻē aʻe e like me ke kīwī, nā pale hōʻike, nā lasers, nā mea uila uila, a me nā paipu uila. ʻO nā ʻāpana uila uila tungsten i kēia mau mea hiki ke hana i ka ʻōlinolino kiʻekiʻe, kūpaʻa maikaʻi, a me nā kumu kukui ola lōʻihi, e hālāwai me nā pono noi.

1. Aia kā mākou hale hana ma Luoyang City, Henan Province. He wahi hana ʻo Luoyang no nā mines tungsten a me molybdenum, no laila, loaʻa iā mākou nā mea maikaʻi loa i ka maikaʻi a me ke kumukūʻai;
2. Loaʻa i kā mākou hui nā limahana loea me ka ʻoi aku o 15 mau makahiki o ka ʻike, a hāʻawi mākou i nā hoʻonā a me nā manaʻo no kēlā me kēia mea kūʻai aku.
3. ʻO kā mākou huahana a pau e nānā pono i ka maikaʻi ma mua o ka lawe ʻia ʻana.
4. Inā loaʻa iāʻoe nā waiwai hemahema, hiki iāʻoe ke hoʻokaʻaʻike mai iā mākou no ka uku.

1. Nā mea uila a me nā mea hoʻoheheʻe: Hoʻohana ʻia ka uea Tungsten ma ke ʻano he electron emitter a me ka mea hoʻomehana no nā pu electron wela ma ia mau noi. Hoʻohana maʻamau ʻia lākou i loko o nā mea hoʻoheheʻe e like me nā paipu electron wela, nā microscopes electron, a me nā mea hana ionization gas.
2. Mālamalama kukui: Ma muli o kona hiki ke hoʻokuʻu i ke kukui'ālohilohi i nā wela kiʻekiʻe a me kona kū'ēʻana i ka hakiʻana, hoʻohana nuiʻia ke kaula tungsten ma keʻano he kumu kukui i nā'ōpuʻu incandescent kuʻuna.
3. ʻO ka mea hoʻoheheʻe kū'ē: ʻO ke kiʻekiʻe heheʻe a me ke kiʻekiʻe kiʻekiʻe o ka wela o ka uea tungsten e lilo ia i mea kūpono no nā mea hoʻomehana kū'ē. Hoʻohana pinepine ʻia lākou i loko o ka hale a me nā ʻoihana hoʻomehana uila e like me nā umu uila, umu, a me nā hao.
4. Hoʻopili a ʻokiʻoki: Hoʻohana maʻamau ʻia ka uea Tungsten e like me nā mea electrode i ka hoʻoheheʻe ʻana i ka ikehu kiʻekiʻe a me nā kaʻina hana e like me ka argon arc welding, laser cutting, a me electron beam welding. ʻO kona wahi hoʻoheheʻe kiʻekiʻe a me ka pale ʻana i ka corrosion e lilo ia i mea koho maikaʻi loa no ka hoʻomaka ʻana arc a me ka hoʻokuʻu ʻana i kēia manawa i kēia mau kaʻina.
5. Nā mea hoʻoheheʻe kemika: Ma kekahi mau mea hoʻoheheʻe kemika, ua hoʻohana ʻia nā uea tungsten ma ke ʻano he catalysts a me nā mea kākoʻo e hoʻomaikaʻi ai i ka maikaʻi o ka hopena a me ke kūpaʻa.
Ma kahi o nā noi i luna, ua hoʻohana nui ʻia ke kelepona tungsten i ka ʻoihana textile, aerospace, ʻoihana nuklea, a me nā kula olakino.
Pono e hoʻoholo ʻia ke anawaena o ka uea tungsten e like me ke ʻano o ka noi kikoʻī. ʻO ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o ke anawaena, ʻoi aku ka liʻiliʻi o ka lole a me ka haehae ʻana i ka uea tungsten, akā e emi ana ka hiki ke amo a me ke ola lawelawe. No laila, pono e koho e like me nā pono kiko'ī.
He hopena koʻikoʻi ka mea o ka uea tungsten i kāna noi. ʻOi aku ka ikaika o ka wela kiʻekiʻe a me ka pale corrosion ma mua o ka tungsten alloy. No laila, i nā kūlana e koi ʻia ai ka hoʻomaʻemaʻe kiʻekiʻe a me ke kūpaʻa corrosion kiʻekiʻe, pono e koho i ka uea tungsten maʻemaʻe; ʻOi aku ka ikaika a me ka ductility o Tungsten alloy, e kūpono ana ia no kekahi mau noi kūikawā e like me ka mīkini uila, nā lako uila uila, a me nā ʻano ʻē aʻe.
ʻO ka manawa hoʻoheheʻe o ka uea tungsten i hoʻomehana ʻia i loko o ka vacuum e pili ana i ka helu evaporation o tungsten. A ʻo ka hoʻomehana ʻana o ka uea tungsten i ka ea e hana i ka tungsten oxide. ʻO ka helu heheʻe o ka tungsten he 3410 degere. ʻO ka helu heheʻe o ka tungsten oxide, WO3, he 1400-1600 degere. Ma lalo o nā kūlana hana maʻamau, ʻo ka mahana o ka filament ma kahi o 2500 degere, a ʻo WO3 wikiwiki e vaporizes i kēia mahana, e hoʻoheheʻe koke ai ka filament i ka lewa.
