Metala Makamae Re no ka huila wela wela
wehewehe
ʻO Rhenium (Re) kahi metala refractory laʻa a makamae i loaʻa nā waiwai kūʻokoʻa i makemake nui ʻia no nā noi like ʻole.He keʻokeʻo keʻokeʻo, metala kaumaha me kahi helu heheʻe kiʻekiʻe a me kahi kiʻekiʻe kiʻekiʻe, e lilo ia i mea kūpono no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe.
ʻO kekahi o nā noi mua o ka rhenium i ka hana ʻana i nā ʻāpana wela wela no ka hoʻohana ʻana i nā mīkini jet.ʻOiaʻiʻo, ma kahi o 70% o ka rhenium o ka honua i hoʻohana ʻia ma kēia ʻano.Hoʻohui ʻia ka Rhenium i kēia mau ʻāpana e hoʻomaikaʻi i kā lākou hana wela kiʻekiʻe, me ko lākou ikaika, paʻa, a me ke kūʻē ʻana i ka ʻaʻahu a me ka corrosion.
ʻO kekahi hoʻohana koʻikoʻi o ka rhenium i ka hana ʻana i nā catalysts platinum-rhenium.Hoʻohana ʻia kēia mau catalysts i ka ʻoihana kemika e paipai i ka hoʻololi ʻana o nā hydrocarbons a me nā mea hoʻohui ʻē aʻe i mau huahana pono, e like me ka ʻaila, plastics, a me nā mea ʻē aʻe.
Ma waho aʻe o kēia mau noi, ua hoʻohana ʻia ka rhenium ma nā ʻano ʻē aʻe, e like me ka ʻoihana aerospace no nā rocket nozzles a ma ka ʻoihana uila no nā pili uila a me nā mea ʻē aʻe.Ma muli o kona liʻiliʻi a me ke kumukūʻai kiʻekiʻe, ua manaʻo ʻia ka rhenium he metala makamae a ua waiwai ʻia no kāna mau waiwai kūʻokoʻa a me ka laulā o nā noi.
