ʻO ka ʻokoʻa ma waena o ka mīkini uea keleawe a me ka mīkini uea alumini

ʻO ka ʻokoʻa ma waenamīkini uwea keleawea me ka mīkini uwea alumini:

1. Okoa metala densities:
ʻO ka nui o ke keleawe: 8.9 * 10 cubic kg / m3
ʻO ka nui o ka alumini: 2.7 * 10 cubic kg / m3
ʻO ka mānoanoa o ke keleawe he aneane ʻekolu manawa ko ka alumini.Me ka helu like o nā wili metala, ʻoi aku ka liʻiliʻi o ke kaumaha o nā mīkini uea alumini ma mua o nā ʻenekini keleawe keleawe.Ma ke ʻano o ka maikaʻi, me ka nānā ʻole i ka hana uea a me ke ola lawelawe, ʻoi aku ka maikaʻi o nā mīkini uea keleawe ma mua o nā uea alumini.

2. Hana ʻia:
I ka wā o ke kaʻina hana, hoʻokomo ʻia ke kaʻa i loko o ka uea, a he palupalu ka uea alumini i ka maikaʻi, haʻahaʻa haʻahaʻa, a maʻalahi hoʻi e haki.
Paʻi ʻia ka uea keleawe a huki ʻia paha:
A. Loaʻa iā ia ka conductivity uila maikaʻi a hoʻohana pinepine ʻia i ka hana ʻana i nā uea, nā kaula, nā pulupulu, etc.
B. He maikaʻi loa ka conductivity thermal o ka uea keleawe, a hoʻohana ʻia ia i ka hana ʻana i nā mea hana magnetic a me nā mea hana pono e pale ʻia mai ka hoʻopilikia ʻana, e like me nā panana a me nā mea lele.
C. ʻO ka hope loa, he plasticity maikaʻi ka uea keleawe a ua maʻalahi ke hana ma ke kaomi wela a me ke kaomi anu.He maikaʻi loa nā ʻano mechanical o ke kaula keleawe.ʻO ka lōʻihi o ke kaula keleawe he ≥30.ʻO ka ikaika tensile o ke kaula keleawe he ≥315.
No laila, i nā kaʻa uila, i ka hoʻohālikelike ʻana, ʻo ka helu kūpono o nā uea keleawe he ʻelua paha ia o nā uea alumini no nā kaʻa me ka mānoanoa like o nā coils.

3. hiki ke halihali
No ka laʻana, inā like ka nui o ka nui o nā wili, inā he 5 amps ke kaha lawe o ka uea aluminika i kēia manawa, a laila ʻo ka hiki ke lawe i kēia manawa o ka uea keleawe ma kahi o 6 amps.Eia kekahi, hana lōʻihi ka mīkini uea alumini a hiki i ka wela, e hōʻino ai i ke kaʻa.
ʻAʻole i loaʻa i ke kaʻa uila keleawe ke kūlana, paʻa ka hana, a hiki ke hana no ka manawa lōʻihi.

4. ke kumukuai
Ma ke ʻano o ke kumukūʻai, ʻoi aku ka maikaʻi o ke kumukūʻai o nā mīkini uea alumini.Ma muli o kēia, i kekahi mau kaua kumukūʻai, ʻoi aku ka nui o nā huahana o nā mīkini uea alumini ma mua o ʻelua ʻoi aku ka liʻiliʻi e like me nā huahana o nā mīkini uea keleawe, kahi e koi ai i nā mea kūʻai aku waena a haʻahaʻa e kūʻai i ka nui.
No laila, i ke koho ʻana i kahi kaʻa, ʻoi aku ka maikaʻi o ke koho ʻana i ka mīkini uea keleawe, a ʻo ia ka mīkini uea keleawe maʻemaʻe.ʻO kekahi mau hale hana, i mea e mālama ai i nā kumukūʻai, hoʻohana pinepine i nā motika uea alumini keleawe, e kuhi hewa ana nā mea kūʻai aku he mau motika uea keleawe lākou, e mālama i ke kālā ke hoʻohālikelike ʻia i nā motika keleawe uea maʻemaʻe, akā ua maʻalahi lākou e ʻeha.
