He aha nā mea maikaʻi a me nā pōʻino o nā mea kikoʻī granite i hoʻohālikelike ʻia me nā mea metala?

ʻO ka mea mua, nā mea maikaʻi o nā mea kikoʻī granite
1. ʻO ka paʻakikī kiʻekiʻe a me ke kū'ēʻana: Granite, ma keʻano he pōhaku paʻakikī maoli, he kiʻekiʻe loa ka paʻakikī a me ke kū'ēʻana. Hāʻawi kēia i nā mea kikoʻī granite e mālama i ka pololei o ka ʻili a me ka paʻa i ka wā lōʻihi o ka hoʻohana ʻana, a ʻaʻole maʻalahi ke ʻaʻahu a ʻohi ʻia.
2. ʻO ke koena haʻahaʻa o ka hoʻonui ʻana i ka wela: He liʻiliʻi ka coefficient o ka hoʻonui wela o ka granite, no laila hiki iā ia ke mālama i ke kūpaʻa maikaʻi i ke kaiapuni me nā loli wela nui. He mea koʻikoʻi kēia ma kahi e pono ai nā ana kikoʻī kiʻekiʻe.
3. Ke kū'ē kū'ē ikaika: He kū'ē maikaʻi ka Granite i nāʻano mea kemika, a hiki ke mālama i ka hana paʻa ma nā wahi hana paʻakikī.
4. ʻAʻohe mālama kūikawā: Ke hoʻohālikelike ʻia me nā ʻāpana metala, ʻaʻole pono nā mea kikoʻī granite kūikawā anti-corrosion a me ka anti-rust lapaʻau, a ʻoi aku ka haʻahaʻa o ke kumukūʻai mālama.
ʻO ka lua, nā hemahema o nā mea kikoʻī granite
1. Ke kaumaha nui: ʻOi aku ka kiʻekiʻe o ka nui o ka granite, no laila ʻoi aku ka nui o ka nui o nā mea granite ma mua o nā mea metala. ʻO kēia, i kekahi ʻano, kaupalena i kāna noi ʻana i nā kūlana e koi ʻia ai ka hoʻolālā māmā.
2. Paʻakikī paʻakikī kiʻekiʻe: Ma muli o ka paʻakikī kiʻekiʻe loa o ka granite, pono e hoʻohana ʻia nā mea ʻoihana a me nā mea hana i ke kaʻina hana, a ʻoi aku ka kiʻekiʻe o ka paʻakikī a me ke kumukūʻai.
3. Brittleness: i hoʻohālikelike ʻia me ka metala, ʻo ka granite he palupalu a hiki i ka haki ʻana a i ʻole ka pōʻino ke loaʻa i ka hopena a i ʻole ka haʻalulu.
ʻEkolu, nā mea maikaʻi o nā mea metala
1. Hoʻolālā māmā: He haʻahaʻa ka nui o nā mea metala, hiki ke hoʻokō i ka hoʻolālā māmā a hoʻokō i nā koi koʻikoʻi o ke kaumaha ma ka aerospace, automotive a me nā māla ʻē aʻe.
2. He maikaʻi ka uila a me ka thermal conductivity: he mea hoʻokele uila maikaʻi ka metala a he mea hoʻokele wela maikaʻi, e hana ana i nā ʻāpana metala i kahi ākea o nā manaʻo noi i ka uila, uila a me nā kahua ʻē aʻe.
3. ʻO ka hana maʻalahi: ʻO ka paʻakikī o ka hana ʻana o nā ʻāpana metala he haʻahaʻa, a hiki ke hoʻohana ʻia nā ʻano hana a me nā mea hana like ʻole no ka hana ʻana, me ka hana kiʻekiʻe.
ʻEhā, nā hemahema o nā mea metala
1. ʻAi maʻalahi: ʻO nā mea metala e maʻalahi i ka corrosion ma nā wahi humid, acidic a alkaline paha, e pili ana i ke ola lawelawe a me ka paʻa o ka hana.
2. ʻO ka helu nui o ka hoʻonui ʻana i ka wela: ʻo ka coefficient o ka hoʻonui wela o ka metala he ʻano nui, a he maʻalahi ke hoʻololi i ka nui i loko o ke kaiapuni me nā loli wela nui, e pili ana i ka pololei.
3. Pono ka mālama kūikawā: Pono nā mea metala i ka mālama kūikawā e like me ka anti-corrosion a me ka anti-rust i ka wā e hoʻohana ai, a he kiʻekiʻe ke kumukūʻai mālama.

I ka hōʻuluʻulu ʻana, loaʻa i nā mea kikoʻī granite a me nā mea metala ko lākou pono ponoʻī a me nā hemahema. Ke koho ʻana i nā ʻāpana, pono e noʻonoʻo ʻia e like me nā hiʻohiʻona a me nā koi pono. No nā manawa e koi ana i ka pololei kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion, ʻoi aku ka maikaʻi o nā mea kikoʻī granite; No nā noi e koi ana i ka hoʻolālā māmā, ka conductivity uila maikaʻi a i ʻole ka maʻalahi o ka hana ʻana, ʻoi aku ka maikaʻi o nā mea metala. Ma o ke koho kūpono a me ka noi, hiki iā mākou ke hāʻawi i ka pāʻani piha i nā pono o kēia mau mea ʻelua a hāʻawi i ke kākoʻo ikaika no ka hoʻomohala ʻana i nā kahua pili.
