He aha nā ʻano kino o ka granite kikoʻī?

ʻO ka granite precision kahi mea i hoʻohana pinepine ʻia i ka hana ʻana i nā mea hana a me nā mīkini ʻenekinia kiʻekiʻe. He ʻano pōhaku kūlohelohe ia i ʻike ʻia no kona paʻakikī koʻikoʻi, ka nui o ka mānoanoa, a me ke kūpaʻa maikaʻi loa, e lilo ia i mea kūpono no ka hoʻohana ʻana i nā ana pololei a me ka hana ʻana i nā mīkini paʻakikī.

He mea kupaianaha nā ʻano kino o ka granite kikoʻī a hoʻokaʻawale iā ia mai nā mea ʻē aʻe. Eia kekahi o nā ʻano kino koʻikoʻi o ka granite kikoʻī:

1. Paʻakikī: He mea paʻakikī loa a paʻa hoʻi ka granite precision. ʻO kona helu paʻakikī Mohs maʻamau ma kahi o 6.5 a 7, ʻo ia hoʻi he ʻoi aku ka paʻakikī ma mua o ka hapa nui o nā minelala, me ka quartz a me ka feldspar. ʻO kēia ka mea e kū ai ka granite precision i nā ʻōpala, nā dents, a me ke komo ʻana, a hōʻoia i ka mālama ʻana i kona ʻano a me ka pololei i ka hala ʻana o ka manawa.

2. Ka nui o ka paʻa: He nui loa ka paʻa o ka granite precision, me ka nui o 2.6 a 2.8 grams no ke kenimika cubic. ʻO ke ʻano o kēia nui he paʻa ia a hiki ke kū i nā pae kiʻekiʻe o ke kaumaha a me ke kaomi me ka ʻole o ka deforming a i ʻole ka haki ʻana.

3. Paʻa: ʻO ke kūpaʻa o ka granite precision kekahi o kona mau waiwai koʻikoʻi loa. He haʻahaʻa kona coefficient o ka hoʻonui ʻana o ka thermal, ʻo ia hoʻi he kūpaʻa loa ia i nā loli o ka mahana a ʻaʻole e hoʻonui a ʻūlū nui paha ma lalo o nā kūlana maʻamau. ʻO kēia ka mea kūpono no ka hoʻohana ʻana i nā mea hana a me nā mīkini e pono ai nā ana pololei a koi i ke kūpaʻa i ka hala ʻana o ka manawa.

4. Porosity Haʻahaʻa: He haʻahaʻa loa ka porosity o ka granite precision, ʻo ia hoʻi he kūpaʻa loa ia i ka wai a me ka pōʻino kemika. Hōʻoia pū kēia porosity haʻahaʻa i ka maʻalahi o ka granite precision e hoʻomaʻemaʻe a mālama.

5. Ka Hoʻokele Wela: He alakaʻi wela maikaʻi loa ka granite precision, e kūpono ana no ka hoʻohana ʻana i nā wahi i kāohi ʻia e ka mahana. Kōkua kona conductivity wela kiʻekiʻe i ka mālama ʻana i kahi mahana paʻa ma ka ʻili holoʻokoʻa o ka mea, he mea nui ia no nā ana pololei a me nā ʻāpana i mīkini ʻia.

Ma keʻano holoʻokoʻa, ʻo nā waiwai kino o ka granite precision e lilo ia i mea maikaʻi loa no ka hoʻohana ʻana i nā noi ʻenekinia kiʻekiʻe, e like me ka hana ʻana i nā mea hana ʻepekema, ka hana semiconductor, a me ka ʻenehana laser. ʻO kona kūpaʻa, kūpaʻa, a me ke kūʻē ʻana i ka ʻaʻahu a me ka haehae e lilo ia i mea kūpono no ka hana ʻana i nā mea hana a me nā mīkini e pono ai ka pololei i nā wā lōʻihi. ʻO ka granite precision he mea āpau ia e kūpono no ka hoʻohana ʻana i ka hana ʻana i nā huahana kiʻekiʻe, pololei, a hilinaʻi.
