Hoʻohana nui ʻia nā kahua kikoʻī Granite i nā ʻoihana e koi ana i ka pololei kiʻekiʻe a me ke kūpaʻa, e like me ka metrology a me ka hana ʻana. Ma muli o kā lākou kuleana koʻikoʻi i ka mālama ʻana i ka pololei o ka dimensional, kū pinepine kekahi nīnau koʻikoʻi: pehea ka hygroscopic o ka granite, a hiki iā ia ke hoʻololi i loko o kahi ʻano haumākū? He mea nui ka hoʻomaopopo ʻana i nā waiwai hygroscopic o ka granite no ka hōʻoia ʻana e mālama kēia mau kahua i ko lākou kūpaʻa a me ka hana ma nā kūlana hana like ʻole.
ʻO ka Granite, ma ke ʻano he pōhaku kūlohelohe, ua hana ʻia me nā minelala like ʻole, me ka quartz, feldspar, a me ka mica. ʻAʻole like me nā mea e like me ka lāʻau a i ʻole kekahi mau metala, he haʻahaʻa loa ka hygroscopicity o ka granite. ʻO ia hoʻi, ʻaʻole ia e omo i ka nui o ka makū mai ke kaiapuni a puni, ʻoiai i nā kūlana haumākū. ʻO ke ʻano molekala o ka granite, i hana nui ʻia me nā hua minelala paʻa loa, e kūʻē iā ia i ka pehu ʻana a i ʻole ka warping e hana ai ka omo ʻana o ka makū i nā mea ʻē aʻe.
ʻO ka nele o ka omo ʻana o ka makū koʻikoʻi kekahi o nā kumu i makemake nui ʻia ai ka granite no nā kahua kikoʻī. I ka hoʻohālikelike ʻana i nā mea ʻē aʻe e hiki ke hoʻonui a ʻuʻuku paha ma muli o nā loli o ka makū, ʻo ka hygroscopicity haʻahaʻa o ka granite e hōʻoiaʻiʻo ana e noho paʻa ana kona ʻano ʻoiai i nā wahi me nā pae makū e loli mau ana. He mea nui loa kēia ʻano no nā noi e koi ana i ka pololei kiʻekiʻe, kahi e hiki ai i nā loli liʻiliʻi o ka ʻano ke alakaʻi i nā hewa i nā ana.
ʻOiai ʻaʻole omo ka granite i ka makū i kahi nui i ʻike ʻia, hiki i ka makū nui ke hoʻopilikia i kona ʻili. Inā hōʻike ʻia i nā pae makū kiʻekiʻe no nā manawa lōʻihi, hiki i ka ʻili o ka granite ke hōʻiliʻili i kahi makū o ka ʻili, akā ʻaʻole lawa kēia e hoʻoulu ai i ka deformation a i ʻole ka nalowale o ka pololei. ʻO ka ʻoiaʻiʻo, ke mālama pono ʻia a hoʻopaʻa ʻia, kūpaʻa loa nā kahua granite i nā mea pili i ke kaiapuni e like me ka makū, nā loli o ka mahana, a me ka hōʻike ʻana i nā kemika.
He mea nui e hoʻomaopopo ʻia, akā naʻe, he mea nui ka mālama pono ʻana e mālama i nā kahua granite i ke kūlana maikaʻi loa. ʻOiai ʻo ke kūʻē kūlohelohe o ka granite i ka omo ʻana o ka makū he mea nui ia, he mea kūpono nō naʻe ke mālama i kēia mau kahua i nā wahi i kāohi ʻia ai ka makū. Ma nā wahi o ka makū kiʻekiʻe loa, ʻo ka hōʻoia ʻana e mālama ʻia ka kahua i loko o kahi lumi i kāohi ʻia e ke aniau me nā pae mahana a me ka makū like e pale aku i nā mea o waho mai ka hoʻopilikia ʻana i kāna hana.
I ka hopena, ʻaʻole hygroscopic nā kahua kikoʻī granite ma ke ʻano kuʻuna, a ʻo ko lākou hiki ke kū i ka haʻahaʻa kiʻekiʻe me ka ʻole o ka deforming e kūpono ai lākou no nā noi kikoʻī. ʻO ko lākou komo haʻahaʻa o ka makū e hōʻoiaʻiʻo ana e mālama lākou i ko lākou pololei a me ke kūpaʻa, ʻoiai ma nā wahi haʻahaʻa. Eia nō naʻe, no ka hōʻoia ʻana i ka hana lōʻihi, ua ʻōlelo ʻia e mālama a hoʻohana i kēia mau kahua ma nā wahi kahi e kāohi ʻia ai ka mahana a me ka haʻahaʻa. Ma ka hoʻomaopopo ʻana i nā waiwai o ka granite a me ka lawe ʻana i nā hana palekana kūpono, hiki i nā ʻoihana ke hoʻohana piha i ka ikaika a me ke kūpaʻa o ka mea no nā hana kikoʻī kiʻekiʻe.
