Maʻamau 99.95% Tungsten W Waʻa no ka Evaporation
Hoʻohana pinepine ʻia nā moku Tungsten no ka evaporation me ka hoʻohana ʻana i nā kaʻina hana metallurgy pauka. Eia nā ʻanuʻu maʻamau no ka hana ʻana i kahi moku tungsten no ka hoʻoheheʻe ʻana:
Koho waiwai: E koho i ka pauka tungsten metala maʻemaʻe kiʻekiʻe, maʻamau me ka maʻemaʻe o 99.95%, ʻo ia ka mea kumu nui no ka hana ʻana i nā moku tungsten. ʻO ka maʻemaʻe kiʻekiʻe e hōʻoia i ka liʻiliʻi o ka contamination i ka wā e hoʻoheheʻe ʻia. Ka hui ʻana: E hoʻohui pono i ka pauka tungsten me ka hoʻohana ʻana i nā mea hana kūikawā e hoʻokō ai i kahi hui like ʻole a me nā waiwai waiwai. Compaction: Hoʻokomo ʻia ka pauka tungsten i hui ʻia i loko o kahi ʻōpala a hoʻohana ʻia ke kaomi kiʻekiʻe, maʻamau ma o ke kaomi isostatic anu (CIP) a i ʻole kaomi uniaxial. Hoʻopili ke kaʻina hana i ka pauka i loko o kahi ʻano paʻa a paʻa e like me ka geometry waʻa i makemake ʻia. Pre-sintering: Hoʻopili mua ʻia nā ʻāpana tungsten i hoʻopaʻa ʻia i nā wela kiʻekiʻe i kahi ea i hoʻomalu ʻia, e ʻae ana i nā ʻāpana pauka e hoʻopaʻa a hana i kahi ʻano paʻa o ka ikaika hoʻonui. Sintering: Hoʻopili ʻia nā ʻāpana i hoʻopaʻa mua ʻia i kahi kaʻina hana hoʻoheheʻe kiʻekiʻe i loko o kahi lewa a hydrogen. Hoʻonui kēia kaʻina hana i ka mea, hoʻoneʻe i nā pores koena, a hoʻoikaika i ka ulu ʻana o ka palaoa, ka hopena i kahi moku tungsten ikaika a paʻa. ʻO ka mīkini a me ka hoʻopau ʻana: Ma hope o ka sintering, hiki i ka moku tungsten ke hana i nā hana machining e like me ka wili, ka huli ʻana a i ʻole ka wili ʻana no ka hoʻokō ʻana i nā ana hope loa, nā grooves a me ka pau ʻana o ka ʻili e pono ai no ka evaporation kūpono o ka mea i ka wā o ka evaporation. Ka Mana Mana: Ua nānā ʻia nā moku tungsten i hoʻopau ʻia no ka pololei o ka dimensional, ka pono o ka ʻili a me ka hoʻomaʻemaʻe waiwai e hōʻoia i ka hoʻokō ʻana i nā koi i kuhikuhi ʻia no nā noi evaporation.
I loko o ke kaʻina hana, he mea koʻikoʻi nā hana hoʻomalu maikaʻi a me ka nānā ʻana i ke kaʻina hana e hōʻoia i ka hoʻokō ʻana o ka moku tungsten i nā koi koʻikoʻi o ke kaʻina hana hoʻoheheʻe ʻana. Hiki i ka waʻa tungsten hopena ke kū i nā wela kiʻekiʻe a me nā wahi corrosive, e kūpono ana i nā ʻano hana evaporation vacuum ma waena o nā ʻoihana.
Hoʻohana maʻamau ʻia nā waʻa Tungsten i nā kaʻina evaporation vacuum, ʻoi aku ka nui o ka deposition kiʻi ʻoniʻoni a me ka hana semiconductor. Eia kekahi mau noi nui o ka evaporation moku tungsten:
Deposition kiʻiʻoniʻoni lahilahi: Hoʻohana ʻia nā waʻa Tungsten i ke kaʻina hoʻoheheʻe kino (PVD) e hoʻoheheʻe i nā metala a me nā mea ʻē aʻe ma luna o kahi substrate e hana i nā kiʻiʻoniʻoni lahilahi o ka mānoanoa a me ka haku mele. Hoʻohana nui ʻia kēia i ka hana ʻana i nā uhi uila a me ka optical a me ka hoʻonaninani a me ka hana ʻana o ka ʻili. Hana Hana Semiconductor: Ma ka ʻoihana semiconductor, hoʻohana maʻamau nā moku tungsten e waiho i nā mea kiʻiʻoniʻoni lahilahi e like me ka aluminika, titanium a me nā ʻāpana metala ʻē aʻe ma nā wafers silicon. He hana koʻikoʻi kēia i ka hana ʻana i nā kaapuni i hoʻohui ʻia, nā ʻōnaehana microelectromechanical (MEMS), a me nā mea uila ʻē aʻe. Noiʻi a Hoʻomohala: Hoʻohana ʻia nā waʻa Tungsten i loko o ka hale hana a me nā kaiapuni R&D e hoʻopau i nā mea e aʻo ai i kā lākou mau waiwai, hoʻomohala i nā mea kiʻiʻoniʻoni lahilahi hou, a e noiʻi i nā ʻenehana uhi hou. Hoʻopili kēia i nā keʻena noiʻi hoʻonaʻauao, nā hale hana aupuni a me nā hale hana R&D ʻoihana. ʻO ka helu hoʻoheheʻe kiʻekiʻe o Tungsten a me ke kūpaʻa wela maikaʻi loa e lilo ia i mea kūpono no nā crucibles ʻano waʻa i hoʻohana ʻia i nā kaʻina evaporation. Hiki i nā waʻa Tungsten ke kū i nā wela kiʻekiʻe e koi ʻia e evaporate i kahi ākea o nā mea me ka ʻole o ka deformation nui a i ʻole degradation, e hōʻoiaʻiʻo ana i ka waiho ʻana o nā kiʻiʻoniʻoni. Eia kekahi, ʻo ko lākou inertness a me ke kū'ē ʻana i nā hopena kemika e kūpono iā lākou no ka hoʻohemo ʻana i nā mea hana a me nā mea hoʻohui i loko o nā kaiapuni i hoʻomalu ʻia.
ʻO ka holoʻokoʻa, he koʻikoʻi ko nā waʻa tungsten i ka waiho ʻana i nā kiʻiʻoniʻoni lahilahi a he mea nui ia i nā ʻoihana like ʻole e hilinaʻi nei i ka ʻenehana evaporation vacuum e hana i nā mea holomua a me nā mea uila.
