Helium kinoea pahu

Hoʻohana nui ʻia ka Helium i ka ʻoihana koa, ka noiʻi ʻepekema, petrochemical, refrigeration, lāʻau lapaʻau, semiconductor, pipeline leak detection, superconductivity hoʻokolohua, hana metala, hohonu kai luʻu, kiʻekiʻe-precision welding, optoelectronic huahana huahana, etc.

(1) Haʻahaʻa haʻahaʻa haʻahaʻa: Ke hoʻohana nei i ka wahi hoʻolapalapa haʻahaʻa o ka helium wai o -268.9 °C, hiki ke hoʻohana ʻia ka helium wai no ka hoʻoluʻu haʻahaʻa haʻahaʻa.ʻO ka ʻenehana hoʻoluʻu wela haʻahaʻa haʻahaʻa he nui nā noi i ka ʻenehana superconducting a me nā kula ʻē aʻe.Pono nā mea superconducting ma ka wela haʻahaʻa (ma kahi o 100K) e hōʻike i nā waiwai superconducting.I ka hapanui o nā hihia, hiki i ka helium wai ke hoʻokō maʻalahi i kēlā mehana haʻahaʻa loa..Hoʻohana nui ʻia ka ʻenehana Superconducting i nā kaʻaahi maglev i ka ʻoihana halihali a me nā mea hana MRI ma ke kahua lapaʻau.

(2) Hoʻonui Baluna: No ka mea ʻoi aku ka liʻiliʻi o ka nui o ka helium ma mua o ka ea (ʻo 1.29kg/m3 ka nui o ka ea, ʻo 0.1786kg/m3 ka nui o ka helium), a ʻaʻole i hana nā mea kemika, ʻo ia ka ʻoi aku ka palekana ma mua o ka hydrogen (hiki i ka hydrogen ke ahi i ka lewa, pahū paha), hoʻohana pinepine ʻia ka helium e like me ke kinoea hoʻopiha i nā moku ākea a i ʻole nā ​​baluna hoʻolaha.

(3) Nānā a me ka nānā ʻana: Pono e hoʻomaʻalili ʻia nā mea hoʻoheheʻe superconducting o ka nuklear magnetic resonance analyses i hoʻohana mau ʻia i ka nānā ʻana i nā mea kani e ka helium wai.I ka loiloi chromatography kinoea, hoʻohana pinepine ʻia ka helium ma ke ʻano he kinoea lawe.Ke hoʻohana nei i ka maikaʻi permeability a me ka non-flammability o ka helium, helium Ua hoʻohana ʻia i ka ʻike leak leak, e like me ka helium mass spectrometer leak detectors.

(4) Ke kinoea pale: Ke hoʻohana nei i nā waiwai kemika hana ʻole o ka helium, hoʻohana pinepine ʻia ka helium e like me ke kinoea pale no ka wili ʻana o ka magnesium, zirconium, aluminika, titanium a me nā metala ʻē aʻe.

(5) Nā mea ʻē aʻe: Hiki ke hoʻohana ʻia ka Helium e like me ke kinoea kaomi ʻia no ka lawe ʻana i nā mea hoʻoheheʻe wai e like me ka hydrogen wai a me ka oxygen wai ma luna o nā rockets a me nā mokulele i loko o nā mea ʻenekini kiʻekiʻe a me nā reactors nuklea.Hoʻohana ʻia ʻo Helium ma ke ʻano he mea hoʻomaʻemaʻe no nā mea hoʻoheheʻe atomic, i loko o ke kinoea hui ʻia no ka hanu ʻana i ke kahua o ka hoʻomohala ʻana i ke kai, e like me ke kinoea hoʻopiha no nā thermometer gas, etc.
