ʻO wai kaʻu e koho ai, ka pā alumini a i ʻole ka pā kila kila?

Ke manaʻoʻiʻo nei au he nui nā hoaaloha i loaʻa, i kēia manawa, a kokoke paha e alo i kēlā mau koho. ʻO nā pāpaʻi alumini a me ke kila kila, ʻo ia mau mea ʻelua he mau papa metala maikaʻi loa, hoʻohana pinepine ʻia i nā ʻoihana a me nā māla e like me ke kūkulu ʻana a me ka hoʻonaninani.

Ke kū nei mākou i kahi koho ma waena o nā mea ʻelua, pehea mākou e koho ai e hoʻonui i kā mākou pono? No laila, e nānā mua kākou i nā ʻano o kēia mau mea ʻelua!

1. Kumukuai:

ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka pā kila kila ma mua o ka pā alumini, ma muli o ka mana o ka mākeke a ma muli o nā pilikia kumu kūʻai;

2. Ka ikaika a me ke kaumaha:

Ma ke ʻano o ka ikaika, ʻoiai ʻaʻole paʻa nā papa alumini e like me nā pā kila kila, ʻoi aku ka māmā o ke kaumaha ma mua o nā pā kila kila. Ma lalo o nā kūlana like, aia lākou ma kahi o hoʻokahi hapakolu o ke kaumaha o nā papa kila kila, e hana ana iā lākou kekahi o nā mea nui i hoʻohana ʻia i ka hana mokulele;

3. ʻAiʻino:

Ma kēiaʻano,ʻo nāʻano papaʻelua he hana maikaʻi loa, akā, no ka mea, ua hoʻokumuʻia nā papa kila kila i nā mea e like me ka hao, chromium, nickel, manganese, a me ke keleawe, a ua hoʻohui pūʻia ka chromium, i nā hihia koʻikoʻi, ke kū'ēʻana o ke kila kila. ʻoi aku ka maikaʻi o nā papa.

ʻOiai he kiʻekiʻe ka oxidation a me ke kūpaʻa corrosion o nā papa alumini, hiki i ko lākou ʻili ke lilo i keʻokeʻo ke hoʻoheheʻe ʻia, a ma muli o ko lākou mau waiwai ponoʻī, ʻaʻole kūpono ka alumini no ka hoʻohana lōʻihi ʻana i ka waika nui a me nā wahi alkaline;

4. Thermal conductivity:

Ma ke ʻano o ka thermal conductivity, ʻoi aku ka maikaʻi o ka conductivity wela o nā pā alumini ma mua o nā pā kila kila, ʻo ia kekahi o nā kumu nui e hoʻohana mau ʻia ai nā pā alumini i nā radiator kaʻa a me nā ʻāpana ea;

5. Hoʻohana:

Ma ke ʻano o ka hoʻohana ʻana, ʻoluʻolu a maʻalahi nā papa alumini e ʻoki a hoʻohālikelike ʻia, ʻoiai ʻo nā papa kila kila hiki ke paʻakikī ke hoʻohana ma muli o ko lākou pale ʻana i ka lole kiʻekiʻe, a ʻoi aku ko lākou paʻakikī ma mua o ka alumini, ʻoi aku ka paʻakikī o ke ʻano;

6. Conductivity:

Ke hoʻohālikelike ʻia i ka hapa nui o nā metala, ʻaʻole maikaʻi ka conductivity uila o nā pā kila kila, ʻoiai ʻo nā pā alumini he mea mana maikaʻi loa. Ma muli o ko lākou conductivity kiʻekiʻe, ke kaumaha māmā, a me ka pale ʻana i ka corrosion, hoʻohana pinepine ʻia lākou i ka hana ʻana i nā laina mana kiʻekiʻe-voltage;

7. Ka ikaika:

Ma ke ʻano o ka ikaika, inā ʻaʻole i noʻonoʻo ʻia nā mea kaumaha, ʻoi aku ka ikaika o nā pā kila kila ma mua o nā pā alumini.

I ka hōʻuluʻulu ʻana, hiki ke koho ʻia nā papa i nā hiʻohiʻona hoʻohana o kēia manawa. Hiki ke hoʻohana ʻia nā pā kila kila no nā pā e pono ai ka ikaika kiʻekiʻe. Eia nō naʻe, ʻoi aku ka maikaʻi o nā papa alumini no nā kūlana e koi ana i ka māmā, nā koi hoʻoheheʻe ʻana, a me nā ʻano hiʻohiʻona hou aʻe.
