He aha nā pōmaikaʻi o nā papa granite?

Hoʻokumu ʻia nā papa granite mai nā papa marble lalo. Ma hope o nā miliona mau makahiki o ka ʻelemakule, paʻa mau ko lākou ʻano, e hoʻopau ana i ka pilikia o ka deformation ma muli o nā loli maʻamau. ʻO kēia mea granite, koho maikaʻi ʻia a kau ʻia i ka hoʻāʻo kino koʻikoʻi, ke kaena nei i nā kristal maikaʻi a me kahi ʻano paʻakikī, e kaena ana i ka ikaika compressive o 2290-3750 kg/cm² a me ka paʻakikī o 6-7 ma ka pālākiō Mohs.

1. ʻO ka nānā nui ʻana i ka pololei paʻa a me ka maʻalahi o ka mālama ʻana, ua hōʻike ʻia nā papa pōhaku granite i kahi microstructure maikaʻi, kahi ʻili maʻemaʻe, pale ʻole, a me ka haʻahaʻa haʻahaʻa.

2. Ma hope o ka wā kahiko maoli, hoʻopau nā papa pōhaku granite i nā koʻikoʻi o loko, ka hopena i kahi mea paʻa, non-deformable.

3. Kūleʻa lākou i nā waikawa, alkalis, corrosion, a me ka magnetism; pale lākou i ka makū a me ka ʻōpala, maʻalahi lākou e hoʻohana a mālama. Loaʻa iā lākou ka helu hoʻonui laina haʻahaʻa a liʻiliʻi ka hopena e ka wela.

4. ʻO nā hopena a i ʻole nā ​​ʻōpala ma ka ʻili hana e hana wale i nā lua, me ka ʻole o nā kua a i ʻole nā ​​​​burrs, ʻaʻohe hopena i ka pololei o ke ana ʻana.

5. Hana ʻia nā papa granite mai nā papa pōhaku lalo. Ma hope o nā miliona mau makahiki o ka ʻelemakule, paʻa loa ko lākou ʻano, e hoʻopau ana i ka pilikia o ka deformation ma muli o ka piʻi ʻana o ka mahana. ʻO ka granite, i koho maikaʻi ʻia a hoʻāʻo ikaika ʻia, kaena i nā kristal maikaʻi a me kahi ʻano paʻakikī. ʻO kona ikaika compressive hiki i 2290-3750 kg / cm², a hiki i kona paʻakikī i 6-7 ma ka pālākiō Mohs.
