1. Koko'o Kino A me Kimia Waiwai O Pure Tungsten & Hana Hana Pono
I ka hana ʻenehana hou, ua lilo nā mea tungsten maʻemaʻe i mea koho no nā ʻoihana he nui ma muli o ko lākou ʻano kino a me nā waiwai kemika. Ma ke ʻano he mea hana tungsten alloy ʻoihana, ʻike mākou i ka waiwai hoʻolālā o ka tungsten maʻemaʻe i nā noi ʻoihana.
Hoʻokaʻawale ʻia ka tungsten maʻemaʻe e ka helu heheʻe kiʻekiʻe loa o ka ʻoihana (3,422 degere) a me ke kiʻekiʻe kiʻekiʻe ma waena o nā metala kumu (19.3 g/cm³), e lilo ana ia i mea pono no nā ʻoihana kiʻekiʻe-me ka hana uila, semiconductor, photovoltaics, a me nā mea lapaʻau. Hiki i ka tungsten maʻemaʻe ke hoʻomau i ka paʻa o ka hoʻoheheʻe ʻana i nā wahi wela loa, ʻoiai ʻo kona kiʻekiʻe kiʻekiʻe e hāʻawi i ka pale pono a me ka hana kaulike.
Mai kahi hiʻohiʻona paʻa kemika, hōʻike ka tungsten maʻemaʻe i ke kūpaʻa corrosion kiʻekiʻe ma ka lumi a me nā mahana haʻahaʻa, e kūʻē ana i nā hopena me nā ʻakika ʻoihana, nā kumu, a me nā hopena corrosive ʻē aʻe. Hoʻolilo kēia waiwai i ka tungsten maʻemaʻe i koho maikaʻi loa no ka hoʻoheheʻe ʻana i nā mea hao, nā kapuahi ulu aniani, a me nā mea hoʻoheheʻe wela kiʻekiʻe. Hoʻohui hou, hōʻike ka tungsten maʻemaʻe i ka conductivity uila ikaika a me ka conductivity thermal, e hoʻokō ana i nā koi hoʻokele wela o nā mea uila.
No nā mea hana B2B, ʻo ke koho ʻana i -kiʻekiʻe kiʻekiʻe maʻemaʻe tungsten pili pono i ka hilinaʻi a me ka hoʻokūkū mākeke o nā huahana hope. ʻO kā mākou huahana tungsten maʻemaʻe e hoʻokō me nā kūlana honua (ASTM B760, ISO 4402), e hōʻoia ana i kēlā me kēia pūʻulu e hoʻokō i nā koi ʻenehana koʻikoʻi.
2. -Ke Ki'eki'e Ke Ki'eki'e Ka Mana'o Koi: Nā Koina Tungsten o ka 'Oihana Hana 'Eleke.
ʻO ka ulu wikiwiki ʻana o ka ʻoihana hana uila honua e alakaʻi pololei i ka nui o ka noi no nā mea tungsten maʻemaʻe. ʻOi aku i ka hana semiconductor, ka pahu LED, ka hana hōʻike pālahalaha, a me nā ʻāpana pāhana ikehu hou, ke hoʻonui wikiwiki nei nā noi tungsten.
I ka hana semiconductor, hana nui ka tungsten maʻemaʻe ma ke ʻano he mau papa pili a me nā mea puka i loko o nā chips, me kona haʻahaʻa haʻahaʻa e hōʻoia ana i ka hoʻouna ʻana i ka hōʻailona kiʻekiʻe. Hoʻohana ka ʻoihana LED i ka helu heheʻe ʻokoʻa o ka tungsten maʻemaʻe a me nā waiwai conductivity thermal no nā substrates chip LED a me nā hale hoʻoheheʻe wela. Me ka hoʻolaha ʻana i nā ʻōnaehana kamaʻilio 5G, ʻike ʻia nā mea uila -kiʻekiʻe a me ka mana kiʻekiʻe{5}} i ka ulu nui ʻana o ka koi tungsten maʻemaʻe.
Hōʻike pū ka ʻāpana metallurgy vacuum i ka hoʻonui mau ʻana i ka noi tungsten. Ma ka uhi ʻana i ka ʻūhā, ka hoʻoheheʻe ʻana a me nā kaʻina like, pono e hana paʻa nā kīʻaha tungsten maʻemaʻe, nā waʻa, a me nā mea hoʻopaʻa i loko o nā kaiapuni maloʻo kiʻekiʻe, e pili pono ana i ka hoʻohua ʻana a me ka maikaʻi o ka hana ʻana. Hoʻolilo kēia i ke kūʻai ʻana i -mea kiʻekiʻe maʻemaʻe tungsten i mea koʻikoʻi i ka hoʻokūkū ʻoihana.
Ke ulu wikiwiki nei nā mea hana kiʻi lāʻau (e like me CT tube anodes) a me nā ʻāpana aerospace i ka ulu wikiwiki ʻana i nā noi tungsten. Ke koi nei kēia mau noi i nā kūlana hilinaʻi kiʻekiʻe loa, no ka mea, hiki i nā hemahema waiwai ke hopena i nā poho waiwai nui.
3. Hoʻohālikelike Hana: Pure Tungsten Vs. Nā mea ʻokoʻa a me ka nānā ʻana i ke kumukūʻai
I nā hoʻoholo kūʻai, pono e kaupaona pinepine nā keʻena kūʻai ʻoihana i ka tungsten maʻemaʻe i nā mea ʻē aʻe e like me ka molybdenum, tantalum, a me ka nickel. Hāʻawi kēia i nā hoʻohālikelike kikoʻī:
- 【Lae hehee a me -Paa Paa Paa Kiekie】 He 3,422 degere ko ka tungsten maʻemaʻe ma mua o ka molybdenum (2,617 degere) a me ka nickel (1,455 degere). No nā noi e koi ana i ka paʻa -kiʻekiʻe kiʻekiʻe, ʻo ka tungsten maʻemaʻe ke koho kūpono wale nō. ʻOiai ʻoi aku ka kiʻekiʻe o ke kumu kūʻai, ʻoi aku ka haʻahaʻa o nā kumukūʻai hoʻohana no ka wā lōʻihi ma muli o ka lōʻihi o ke ola o ka huahana a me ka emi ʻana o nā helu hāʻule.
- 【Hōnaehana a me ka pale pale】 Me ka mānoanoa o 19.3 g/cm³, ʻo ka tungsten maʻemaʻe kekahi o nā metala maʻamau kiʻekiʻe loa. Ma nā noi pale X-ray a me ka gamma-, loa'a ka tungsten ma'ema'e i nā hopena pale like me ka li'ili'i loa a me ke kaumaha, e hā'awi ana i nā pono kūpono ma ka lewa-nā noi i kāohi 'ia e like me nā mea lapa'au a me nā mea aerospace.
- 【Kumu ʻOi aku i loko o nā ʻoihana kahi i ʻoi aku ka hilinaʻi
