ʻO nā pahu hau: Aluminum VS. kila

Ma ZX, hana mākou i nā pahu alumini a me ke kila. ʻO kā mākou hui o nā mīkini loea, nā ʻenehana a me nā limahana hana i ʻoi aku ma mua o 20 mau makahiki o ka ʻike i ka lawelawe ʻana i ka mea inu, scuba, lāʻau lapaʻau, palekana ahi a me nā ʻoihana kūikawā.

I ke koho ʻana i ka metala no ka pahu hau, he mea nui e noʻonoʻo i ka hiki ke hana holoʻokoʻa o ka metala i ka wā o ke kaʻina hana (hiki ke hoʻopilikia i ka paʻakikī a me ke kumukūʻai) a me nā ʻano i mālama ʻia ma hope o ka hana ʻana, e pili ana i kāna hana i ka hopena. hoʻohana i nā noi. E aʻo hou e pili ana i nā ʻokoʻa ma waena o nā metala ʻelua e koho i ke kūpono kūpono iā ʻoe!

ʻO ka alumini he mea hoʻoheheʻe ʻole, non-magnetic, a ʻaʻole hoʻi i ka metala. He mea maʻalahi hoʻi ia e hana pū me, e lilo ia i koho kaulana no nā ʻano noi like ʻole ma nā ʻōnaehana mea kūʻai, kālepa, a me nā ʻoihana. ʻO ke kila, kahi mea ikaika a me ka paʻakikī e hiki ke hoʻololi i nā ʻano like ʻole o nā huila, hāʻawi i kahi ratio ikaika-a-kaumaha maikaʻi, paʻakikī, paʻakikī a me ka ikaika luhi.

Kaumaha

ʻO Aluminum, he metala māmā loa me ka ratio ikaika-a-kaumaha maikaʻi, he 2.7 g/cm3 ke kaumaha, ma kahi o 33% o ke kaumaha o ke kila. ʻO ke kila he mea paʻakikī, me ka nui o ka 7,800 kg / m3.

Koina

ʻOiai ʻaʻole ʻo ka alumini ka metala makamae loa ma ka mākeke, ua ʻoi aku ka nui o ke kumukūʻai ma muli o ka piʻi ʻana o ke kumu kūʻai o ka mākeke maka. ʻO ke kila, ma kekahi ʻaoʻao, ʻoi aku ka liʻiliʻi o ka paona o nā mea ma mua o ka alumini.

ʻAiʻino

Paʻa maoli ka alumini i ka corrosion. ʻO nā ʻāpana alumini ka lōʻihi a hilinaʻi hoʻi i ka haʻahaʻa kiʻekiʻe a me nā kaiapuni kai, ʻaʻole koi i nā kaʻina hana hou e noho kūpaʻa i ka corrosion, e hoʻomaʻamaʻa i ka hana ʻana a hōʻoia i nā waiwai anti-corrosion ʻaʻole e ʻoki a mae i ka wā. ʻAʻole hoʻomohala ke kila i ka ʻili o ka alumini oxide anti-corrosive layer like me ka alumini. Eia nō naʻe, hiki ke uhi ʻia ka mea me nā uhi, pena, a me nā mea hoʻopau ʻē aʻe. ʻO kekahi mau mea kila, e like me ke kila kila, ua hana kūikawā ʻia e pale aku i ka ʻino.

ʻoluʻolu

ʻO ka alumini he malleable a maʻalahi hoʻi e hana pū me. He kūlana kiʻekiʻe o ka elasticity, no laila hiki i nā mea hana ke hana i nā hana paʻakikī me ka ʻole o ka haki ʻana i ka metala. ʻO ka alumini ka koho maikaʻi loa no nā kaʻina wili a me ka hana ʻana i nā ʻāpana me nā paia hohonu a pololei e pono ai ke kūpono i nā pae hoʻomanawanui. ʻOi aku ka paʻakikī o ke kila ma mua o ka alumini, e koi ana i ka ikaika a me ka mana e hana i nā huahana i hana ʻia. Eia nō naʻe, ʻoi aku ka ikaika o ka huahana i hoʻopau ʻia, ʻoi aku ka paʻakikī, a hiki ke pale aku i ka deformation i ka manawa.

Kāhea iā mā˚ou

Ma ZX, hiki i kā mākou hui o nā mea hana akamai ke kōkua iā ʻoe e koho i nā mea kūpono no kāu papahana a hana i nā waiwai kikoʻī āu e pono ai. ʻO ke kila a me ka alumini ka mea maʻalahi, nā mea pono no nā pahu hau. E kelepona mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou hana a me nā huahana!
