niobium strip niobium foil no ka Sintering Furnace
ʻO ke kāʻei Niobium kahi mea metala me ka maʻemaʻe kiʻekiʻe (≥ 99.95%), a ʻo kāna mau hiʻohiʻona nui e pili ana i ka pale wela kiʻekiʻe a me ke kūpaʻa corrosion. ʻO 8.57g/cm ³ ka mānoanoa o ke kaula niobium, a ʻo kona kiʻekiʻe he 2468 ℃. Hoʻohana nui ʻia kēia mau hiʻohiʻona i nā kula e like me ke kemika, electronics, aviation, a me aerospace. He ʻokoʻa nā kikoʻī o nā ʻāpana niobium, me ka mānoanoa mai ka 0.01mm a 30mm a me ka laulā a hiki i 600mm, hiki ke hoʻololi ʻia e like me nā pono kikoʻī. ʻO ke kaʻina hana o ka niobium strip ka nui o ka ʻōwili ʻana, e hōʻoiaʻiʻo ana i ka maʻemaʻe a me ka hana o ka niobium strip.

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.

Hoʻohana maʻamau ʻia nā pahuhopu Molybdenum i nā paipu X-ray no ke kiʻi lāʻau lapaʻau, ka nānā ʻana i nā ʻoihana, a me ka noiʻi ʻepekema. ʻO nā noi no nā pahuhopu molybdenum ka mea nui i ka hoʻomohala ʻana i nā kukui X-hiki no ke kiʻi diagnostic, e like me ka computed tomography (CT) scans a me ka radiography.
Hoʻohana ʻia nā pahuhopu Molybdenum no ko lākou wahi hoʻoheheʻe kiʻekiʻe, e hiki ai iā lākou ke pale i nā wela kiʻekiʻe i hana ʻia i ka wā hana X-ray. Loaʻa iā lākou ka conductivity thermal maikaʻi, kōkua i ka hoʻopau ʻana i ka wela a hoʻolōʻihi i ke ola o ka paipu X-ray.
Ma waho aʻe o ke kiʻi lāʻau lapaʻau, hoʻohana ʻia nā pahuhopu molybdenum no ka hoʻāʻo ʻole luku ʻana i nā noi ʻoihana, e like me ka nānā ʻana i nā welds, nā paipu a me nā ʻāpana aerospace. Hoʻohana ʻia lākou i nā keʻena noiʻi e hoʻohana ana i ka spectroscopy X-ray fluorescence (XRF) no ka nānā ʻana i nā mea a me ka ʻike elemental.
Hiki ke ʻokoʻa ka mahana sintering o ka niobium ma muli o ka noi kikoʻī a me nā mea i hana ʻia. Ma keʻano laulā, he kiʻekiʻe ka helu heheʻe o ka niobium he 2,468 degere Celsius (4,474 degere Fahrenheit). Eia nō naʻe, hiki ke hoʻopaʻa ʻia nā mea i hoʻokumu ʻia i ka niobium ma nā mahana ma lalo o ka helu heheʻe, ʻo ia ka mea maʻamau mai 1,300 a 1,500 degere Celsius (2,372 a 2,732 degere Fahrenheit) no ka hapa nui o nā kaʻina hana sintering. Pono e hoʻomaopopo ʻia ʻo ka mahana sintering pololei o nā mea i hoʻokumu ʻia i ka niobium e pili ana i ke ʻano kikoʻī a me nā koi kaʻina hana sintering.
Aia ka mānoanoa o ka niobium foil ma waena o 0.01mm a me 30mm, e hōʻike ana e hiki ke hoʻopilikino ʻia nā ʻāpana niobium me nā mānoanoa like ʻole e like me nā koi hoʻohana kikoʻī. Eia kekahi, aia nā ʻano nui ʻē aʻe o nā pepa niobium a me nā ʻāpana i loaʻa no ke koho ʻana, e hōʻike ana i ka hoʻohui ʻana i ka mānoanoa, hiki ke hoʻoponopono ʻia nā ʻāpana nui ʻē aʻe e like me ka laulā o ka niobium e like me ka mea e pono ai.
ʻAʻole maʻemaʻe ka Niobium i ka wela lumi. Ua manaʻo ʻia he mea paramagnetic, ʻo ia hoʻi, ʻaʻole ia e paʻa i kahi māla magnetic ke wehe ʻia kahi māla magnetic waho. Eia naʻe, hiki i ka niobium ke lilo i nawaliwali i ka mane ke ʻike ʻia i nā mahana haʻahaʻa haʻahaʻa loa a i hui pū ʻia me nā mea ʻē aʻe. Hoʻohana maʻamau ʻo Niobium i kona ʻano maʻemaʻe ʻaʻole no kāna mau waiwai magnetic akā no kona kūpaʻa maikaʻi ʻana i nā mahana kiʻekiʻe a me ka corrosion, e waiwai ai ia i nā ʻano ʻenehana a me nā noiʻi ʻepekema.
