Metala W me ka paakiki kiekie
wehewehe
ʻO Refractory Metal W kahi mea i ʻimi nui ʻia i nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa.Loaʻa iā ia ke kūpaʻa kiʻekiʻe kiʻekiʻe, kūpono ia no ka hoʻohana ʻana i nā noi e pono ai ke kū i ka wela loa.Hoʻohui ʻia, loaʻa iā ia ka paʻakikī kiʻekiʻe, kahi kūpono no ka hoʻohana ʻana i nā noi kiʻekiʻe.
ʻO kekahi o nā noi maʻamau o Refractory Metal W i ka hana ʻana i nā tungsten collimator grids lahilahi.He mea koʻikoʻi kēia mau grids i nā noi kiʻi lāʻau lapaʻau, no ka mea e kōkua lākou i ke ʻano o nā kukuna radiation i hoʻohana ʻia i nā kaʻina diagnostic.
ʻO kekahi noi ʻana o Refractory Metal W i ka hana ʻana i nā wela wela no nā kānana deflector o nā reactors thermonuclear fusion.Hiki i nā puʻu wela ke hoʻopau i ka wela i hana ʻia i ka wā o ka fusion reaction, he mea nui ia no ka mālama ʻana i nā kūlana reactor paʻa.
ʻO ka mea hope loa, hoʻohana ʻia ʻo Refractory Metal W i ka hana ʻana i nā nozzles tungsten wela kiʻekiʻe no nā ʻenekini aero.Aia kēia mau nozzles i nā wela wela a me nā pae kiʻekiʻe o ka lole, e hana ana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa wela o Refractory Metal W kūpono no kēia noi.
