He aha ke kūpaʻa wela o ka granite i nā lako ana pololei?

He mea maʻamau ka Granite i hoʻohana ʻia i nā lako ana pololei ma muli o kona kūpaʻa wela maikaʻi loa. ʻO ke kūpaʻa wela o ka granite e pili ana i kona hiki ke mālama i kona kūpaʻa dimensional a pale aku i ka deformation ma lalo o nā mahana loli. He mea koʻikoʻi kēia i nā lako ana pololei, no ka mea, ʻo nā loli i nā ana mea hiki ke alakaʻi i nā ana pololei ʻole a me ka emi ʻana o ka maikaʻi.

Hōʻike ka Granite i ke kūpaʻa wela kiʻekiʻe ma muli o kona coefficient haʻahaʻa o ka hoʻonui wela. ʻO ke ʻano kēia, hoʻonui a ʻuʻuku iki ia ma muli o nā loli o ka mahana, e hōʻoiaʻiʻo ana e kūlike mau ana nā ana o ka mea ana. Eia kekahi, he kūpaʻa wela maikaʻi loa ka granite a hiki ke kū i nā mahana kiʻekiʻe me ka ʻole o ka warping a i ʻole deforming.

He mea nui loa ke kūpaʻa wela o ka granite no nā lako ana pololei e like me nā mīkini ana hoʻonohonoho (CMM) a me nā pae. Hilinaʻi nā CMM i ke kūpaʻa o kā lākou mau kumu granite e hōʻoia i nā ana pololei a hiki ke hana hou ʻia. ʻO kēlā me kēia hoʻonui wela a i ʻole ka ʻūlū ʻana o ka granite hiki ke hana i nā hewa ana a hoʻopilikia i ka hilinaʻi o nā lako.

Loaʻa pū nā paepae i hoʻohana ʻia ma ke ʻano he mau ʻili kuhikuhi no ka nānā ʻana i ka ʻāpana hana mai ke kūpaʻa wela o ka granite. ʻO ke kūpaʻa o ka mea i nā loli dimensional i hoʻoulu ʻia e ka mahana e hōʻoiaʻiʻo ana e mālama ka paepae i kona pālahalaha a me ka pololei, e hāʻawi ana i kahi kumu hilinaʻi no nā ana pololei.

Ma waho aʻe o ke kūpaʻa wela, loaʻa i ka granite nā waiwai ʻē aʻe e pono ai no nā lako ana pololei, me ke kiʻekiʻe o ka paʻakikī, ka porosity haʻahaʻa a me ka liʻiliʻi o ka deformation ma lalo o ke kaumaha. Hoʻomaikaʻi hou kēia mau hiʻohiʻona i ka pololei a me ka hilinaʻi o ka hāmeʻa.

Ma keʻano holoʻokoʻa, ʻo ke kūpaʻa wela o ka granite i nā lako ana pololei he mea nui ia i ka hōʻoia ʻana i ka pololei a me ke kūlike o ke ana ʻana. Ma ka hoʻohana ʻana i nā mea me ka liʻiliʻi o ka hoʻonui wela a me ke kūpaʻa wela maikaʻi loa, hiki i nā mea hana ke hilinaʻi i ke kūpaʻa o kā lākou lako ma luna o kahi ākea o ka mahana hana, e hoʻomaikaʻi hope ana i ka kaohi maikaʻi a me ka pololei o ke kaʻina hana ana.
