kahua noi o tungsten

ʻO Tungsten ka mea i kapa ʻia ʻo wolfram, he mea kemika me ka hōʻailona o W a ʻo ka helu atomic ʻo 74. He metala kūʻokoʻa ia i loaʻa i kahi ākea ākea i ka ʻenehana hou. ʻO ka metala ʻo Tungsten he metala paʻakikī a loaʻa ʻole. Hiki ke loaʻa ma ka honua wale nō i loko o nā pūhui kemika. ʻO ka hapa nui o kāna mau mea kemika he tungsten oxide a ʻo ka hapa nui o nā mines tungsten i loaʻa ma Kina. ʻOi loa ma nā panalāʻau ʻo Hunan a me Jiangxi. Ma muli o kona kiʻekiʻe heheʻe, kiʻekiʻe paʻakikī, maikaʻi ka corrosion kū'ē, maikaʻi uila conductivity, a me thermal conductivity, ua lilo ia i kekahi o ka loa koʻikoʻi hana mea i loko o ka 'oihana hou. Hoʻohana nui ʻia ia i ka alloy, electronics, chemical, medical, and other field.

1. Ma ke kahua o Industrial alloys

ʻO ka powder metallurgy ke ala o ka hana ʻana i nā huahana tungsten sintered. ʻO ka pauka Tungsten ka mea waiwai nui a me ka wahi hoʻomaka o nā huahana mineral tungsten. Hana ʻia ka pauka Tungsten ma ka ʻala ʻana a me ka hoʻomehana ʻana i ka tungsten oxide i loko o kahi lewa hydrogen. He mea koʻikoʻi ka maʻemaʻe, ka oxygen, a me ka nui o nā ʻāpana no ka hoʻomākaukau ʻana i ka pauka tungsten. Hiki ke hoʻohui ʻia me nā pauka mea ʻē aʻe e hana i nā ʻano tungsten alloys.

Tungsten carbide-based cemented carbide:

Hoʻohana pinepine ʻia ka tungsten carbide e hui pū me nā metala ʻē aʻe e hoʻomaikaʻi i kāna hana. ʻO nā metala hui pū ʻia me ka cobalt, titanium, ka hao, ke kālā, a me ka tantalum. ʻO ka hopena, ʻoi aku ka kiʻekiʻe o ka carbide cemented tungsten carbide a ʻoi aku ka nui o nā waiwai refractory. Hoʻohana nui ʻia lākou i ka hana ʻana i nā mea hana ʻokiʻoki, nā mea hana mining, uea kaha kiʻi make, a me nā mea ʻē aʻe. Hiki ke hoʻohana nui ʻia i nā noi kūkulu hale kūʻai, nā mea uila, nā mea hana ʻenehana, nā mea pale radiation, a me ka ʻoihana aeronautical.

Palena wela a me ka ʻaʻahu-pale i ka huila:

ʻO ka helu heheʻe o tungsten ka mea kiʻekiʻe loa ma waena o nā metala āpau, a ʻo kona paʻakikī ka lua ma mua o ke daimana. No laila, hoʻohana pinepine ʻia e hana i nā mea hoʻoheheʻe wela a paʻa. No ka laʻana, hana pinepine ʻia nā ʻāpana tungsten a me nā metala refractory ʻē aʻe (tantalum, molybdenum, hafnium) i nā ʻāpana ikaika kiʻekiʻe e like me nā nozzles a me nā ʻenekini no nā rockets. A ua hoʻohana mau ʻia nā alloys o ka tungsten, chromium, a me ka carbon e hana i nā ʻāpana ikaika kiʻekiʻe a paʻa ʻole, e like me nā valves no nā mokulele mokulele, nā huila turbine, etc.

2. Ma ke kahua o ka kemika

Hoʻohana mau ʻia nā pūhui Tungsten e hana i kekahi mau ʻano pena, inika, lubricants, a me nā catalysts. No ka laʻana, hoʻohana ʻia ka tungsten oxide kala keleawe i ka pena, a hoʻohana mau ʻia ka calcium a i ʻole ka magnesium tungsten i nā phosphors.

3. Ma ke kahua kaua

Ua hoʻohana ʻia nā huahana Tungsten e hoʻololi i nā mea uranium alakaʻi a hoʻopau ʻia no ka hana ʻana i nā poʻomanaʻo pōkā ma muli o kā lākou mau mea ʻawaʻawa a me ka mālama ʻana i ke kaiapuni, i mea e hōʻemi ai i ka haumia o nā mea kaua i ke kaiaola. Eia kekahi, hiki i ka tungsten ke hoʻoikaika i ka hana kaua o nā huahana koa ma muli o kona paʻakikī ikaika a me ke kūpaʻa kiʻekiʻe.

Hiki ke hoʻohana ʻia ʻo Tungsten ʻaʻole wale ma nā kahua i luna aʻe akā i ka hoʻokele ʻana, ka ikehu atomika, ka hana moku, ka ʻoihana kaʻa, a me nā māla ʻē aʻe. Inā makemake ʻoe i ka tungsten a i ʻole he nīnau e pili ana. E ʻoluʻolu e kelepona mai iā mākou i kēia manawa.
