Moolelo o Tungsten

ʻO Tungsten kekahi ʻano mea kemika me ka hōʻailona W a loaʻa iā ia ka helu atomic o 74, hiki ke kapa ʻia ʻo wolfram. He paʻakikī ke ʻike ʻia ʻo Tungsten ma ke ʻano he tungsten manuahi, a hoʻokumu mau ʻia ʻo ia e like me nā mea hoʻohui me nā mea ʻē aʻe.

ʻElua ʻano ores ʻo Tungsten. ʻO lākou ka scheelite a me ka wolframite. ʻO ka inoa ʻo Wolfram mai ka mea hope. I ke kenekulia 16, ua hōʻike ka poʻe miners i kahi mineral i hui pū ʻia me ka ʻala. Ma muli o ka ʻeleʻele a me ka huluhulu o kēia ʻano mineral, ua kapa ʻia kēia ʻano oka e nā miners“wolfram”. Ua hōʻike mua ʻia kēia mōʻalihaku hou ma Georgius Agricola’s puke, De Natura Fossilium ma 1546. Ua ʻike ʻia ʻo Scheelite ma 1750 ma Swede. ʻO ka mea mua i kapa ʻia ʻo Tungsten ʻo Axel Frederik Cronstedt. ʻElua ʻāpana ʻo Tungsten, ʻo tung, ʻo ia hoʻi ke kaumaha ma Suedena, a me sten, ʻo ia ka pōhaku. ʻAʻole a hiki i ka hoʻomaka ʻana o nā makahiki 1780, ʻo Juan José de D´Ua ʻike ʻo Elhuyar aia i ka wolfram nā mea like me ka scheelite. Ma ka paʻiʻana o Juan a me kona kaikunāne, hāʻawi lākou i kēia metala hou i inoa hou, wolfram. Ma hope o ia mea, nui aʻe ka poʻe ʻepekema i ʻimi i kēia metala hou.

I ka makahiki 1847. ua hāʻawi aku kekahi ʻenekinia i kapa ʻia ʻo Robert Oxland i kahi patent e pili ana i ka tungsten.

I ka makahiki 1904, ua hoʻopaʻa ʻia nā ʻōpuʻu kukui tungsten mua, kahi i hoʻololi koke i nā huahana ʻē aʻe, e like me nā kukui filament carbon liʻiliʻi ma nā mākeke kukui.

I ka makahiki 1920, no ka hana ʻana i nā kiʻi make me ka paʻakikī kiʻekiʻe, kahi kokoke i ke daimana, hoʻomau ka poʻe i ka hoʻomohala ʻana i nā waiwai o ka carbide cemented.

Ma hope o ke Kaua Honua II, loaʻa ka hoʻokele waiwai a me ka ulu nui. ʻOi aku ka kaulana o Tungsten carbide ma ke ʻano he ʻano mea hana, hiki ke hoʻopili ʻia i nā kūlana he nui.

I ka makahiki 1944, ua paʻi ʻo K C Li, Pelekikena o Wah Chang Corporation ma US, i ke kiʻi ma ka Engineering & Mining Journal i kapa ʻia: "40 Years Growth of the Tungsten Tree (1904-1944)"e hōʻike ana i ka hoʻomohala wikiwiki ʻana o nā noi tungsten like ʻole i ke kahua o ka metallurgy a me ke kemika.

Mai ia manawa, me ka hoʻomohala ʻana o ka hoʻokele waiwai a me ke kaiāulu, ua koi nui ka poʻe i kā lākou mau mea hana a me nā lako, e koi ana i ka hoʻomau mau ʻana o nā huahana tungsten carbide. ʻOiai i kēia manawa, ke noiʻi nei ka poʻe a me ka hoʻomohala ʻana i kēia metala e hāʻawi i ka ʻoi aku ka maikaʻi o ka hana a me ka ʻike.

Eia ʻo ZZBETTER. Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
