Ma ke kahua o ka ʻepekema mea hou, metala magnesium ke lilo nei i mea nui o ka nānā ʻana i ka ʻoihana ma muli o kāna hana maikaʻi loa a me ka hiki ke hoʻohana ākea. Ma ke ʻano he metala māmā loa ma ka honua, hoʻohiki nā waiwai kūʻokoʻa o ka magnesium no ka hoʻohana ʻana i ka aerospace, ka hana kaʻa, nā lako uila, biomedicine a me nā kula ʻē aʻe.
ʻO ka mānoanoa o ka metala magnesium ma kahi o 1.74 g/cubic kenimika, ʻo ia ka hapalua o ka alumini a me ka hapahā o ke kila. Hoʻolilo kēia waiwai māmā i ka magnesium i mea kūpono no nā huahana māmā. I ke ao holoʻokoʻa, me ka piʻi nui ʻana o nā koi no ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana i ka hoʻokuʻu ʻana, ua waiwai nui kēia waiwai o ka metala magnesium e nā mea hana kaʻa a me nā mokulele.
Ma waho aʻe o ka māmā, metala magnesium maikaʻi nō hoʻi ka ikaika a me ka ʻoʻoleʻa. ʻOiai ʻaʻole ikaika e like me ka alumini a me ke kila, i nā noi he nui, ua lawa ka ikaika-a-kaumaha o ka magnesium e hoʻokō i nā koi hoʻolālā. Eia kekahi, he mau waiwai seismic maikaʻi loa ka metala magnesium a hiki ke hoʻopaʻa i ka vibration a me ka walaʻau, e hiki ai iā ia ke hāʻawi i kahi ʻike holo ʻoluʻolu i ka wā e hana ai i ke kino a me nā ʻāpana o nā kaʻa a me nā mokulele.
Hōʻike pū ka metala Magnesium i ka wela a me ka uila maikaʻi, nā waiwai e kaulana nui ai i nā mea uila, e like me nā mea pahu pahu no nā mea like me nā kamepiula, kelepona paʻa, a me nā pahupaʻikiʻi. ʻO nā mea hoʻoheheʻe wela o ka magnesium alloy e kōkua i nā mea uila e mālama i nā mahana haʻahaʻa i ka wā lōʻihi o ka hana, a laila e hoʻolōʻihi i ke ola lawelawe o ka huahana.
E pili ana i ka waiwai kemika, he hana kemika nui ka metala magnesium. Hoʻopili ia me ka oxygen i ka lewa ma ka lumi wela e hana i kahi kiʻiʻoniʻoni oxide. Hiki i kēia kiʻiʻoniʻoni oxide ke pale i ka magnesium i loko mai ka hoʻomau ʻana i ka hana ʻana me ka oxygen, no laila e hāʻawi ai i kekahi kūpaʻa corrosion. Eia nō naʻe, ma muli o ka hana kemika o ka magnesium, ʻaʻole maikaʻi kona pale ʻana i ka corrosion i nā wahi humid e like me ka alumini a me ke kila. No laila, i nā noi kūpono, hoʻohana pinepine ʻia ka ʻenehana lapaʻau ʻili e hoʻomaikaʻi i kona kūpaʻa corrosion.
He mea kūpono ke ha'i aku i ka hiki ke hō'ike 'ia ka metala magnesium ma ka 'oihana lapa'au. No ka mea ʻo ka magnesium kekahi o nā mea pono no ke kino o ke kanaka a he biocompatibility maikaʻi a me ka biodegradability, ke kūkulu nei nā mea noiʻi i nā mea lapaʻau e pili ana i ka magnesium, e like me nā kui iwi a me nā scaffolds, hiki ke hoʻohaʻahaʻa haʻahaʻa, a laila e hōʻemi ana i ka pono o ke ʻoki lua e wehe. ka implant.
6523730 ʻO ka flammability o ka magnesium he mea palekana e pono e noʻonoʻo ʻia i ka wā e hoʻohana ai, ʻoi aku ma lalo o kekahi mau kūlana e like me ke kiʻekiʻe o ka wela a i ʻole ka wili ʻana, kahi e hoʻoulu ai ka lepo magnesium i ke ahi a pahū paha. No laila, koi ʻia nā hana palekana koʻikoʻi i ka wā e lawelawe ai a hoʻoili i ka metala magnesium.
Me ka ulu ʻana o ka ʻenehana, ke hoʻomaikaʻi mau nei ka ʻenehana hana o ka metala magnesium. No ka laʻana, hiki ke hoʻomaikaʻi maikaʻi ʻia ka pale ʻana i ka corrosion a me ka ʻaʻahu ʻana o ka metala magnesium ma o ka hoʻohana ʻana i ka ʻenehana alloy holomua a me ka ʻenehana lapaʻau. I ka manawa like, ke hana ikaika nei ka poʻe noiʻi e hoʻomohala i nā mea hoʻoheheʻe magnesium hou e hoʻomaikaʻi i kā lākou mau waiwai āpau a hoʻonui i kā lākou noi.
I ka pōkole, lilo ka magnesium i hōkū ma ke kahua o ka ʻepekema waiwai ma muli o kona kaumaha māmā, ikaika kiʻekiʻe, maikaʻi loa ka wela a me ka uila, a me ka mālama ʻana i ke kaiapuni a me ka hiki ke biomedical i nā kahua kikoʻī. Me ka hoʻomau mau ʻana o ka hana ʻenehana a me ka hana ʻenehana, loaʻa iā mākou ke kumu e manaʻoʻiʻo ai e pāʻani ka metala magnesium i kahi kuleana nui i nā noi mea e hiki mai ana.
