He aha ke ʻano o ka Granite i hoʻohana ʻia no ka hana ʻana i nā papa ʻili Granite?

Hana ʻia nā pā pōhaku ʻili a me nā mea hana ʻē aʻe mai ka pōhaku kiʻekiʻe. Eia nō naʻe, ʻaʻole kūpono nā ʻano granite āpau no ka hana ʻana i kēia mau mea paahana. No ka hōʻoia ʻana i ka lōʻihi, kūpaʻa, a me ka pololei o nā papa papa pōhaku granite, pono e hoʻokō nā mea granite maka i nā koina kikoʻī. Aia ma lalo iho nā hiʻohiʻona koʻikoʻi i loaʻa i ka granite e hoʻohana ʻia i ka hana ʻana i nā papa papa pōhaku a me nā mea hana e pili ana.

1. Ka paakiki o Granite

ʻO ka paʻakikī o ka granite kekahi o nā mea koʻikoʻi i ke koho ʻana i nā mea maka no nā papa papa pōhaku. Pono e loa'a ka pa'akiki Shore ma kahi o 70. 'O ka pa'akiki ki'eki'e e ho'omau i ka ma'ema'e a me ka lō'ihi o ka ili granite, e hā'awi ana i kahi paepae ana kūpa'a.

Eia hou, ʻaʻole e like me ka hao hoʻoheheʻe ʻia, kūpaʻa ka granite i ka ʻōpala a me ka corrosion, no laila kūpono ia no nā kaiapuni me ka haʻahaʻa kiʻekiʻe a i ʻole ka piʻi ʻana o ka mahana. Inā hoʻohana ʻia ma ke ʻano he papa nānā granite a i ʻole he papa hana, e hōʻoia ka granite i ka neʻe maʻemaʻe me ka ʻole o ka friction makemake ʻole a pipili paha.

2. Kaumaha kikoo o Granite

Ke hoʻokō ka granite i ka paʻakikī i koi ʻia, ʻo kona gravity kikoʻī (a i ʻole ka paʻa) ka mea koʻikoʻi e hiki mai ana. Pono ka ʻumekaumaha kikoʻī ma waena o 2970–3070 kg/m³ ka Granite i hoʻohana ʻia no ka hana ʻana i nā papa ana. He kiʻekiʻe kiʻekiʻe ka Granite, e kōkua ana i kona kūpaʻa wela. ʻO ia ke ʻano o ka liʻiliʻi ʻana o nā papa ili granite e nā loli wela a i ʻole ka haʻahaʻa, e hōʻoia ana i ka pololei a me ka pololei i ka wā o nā ana. ʻO ke kūpaʻa o ka mea e kōkua ai i ka pale ʻana i ka deformation, ʻoiai ma nā wahi me nā ʻano wela.

3. Ka ikaika compressive o Granite

Pono ka Granite i hoʻohana ʻia no ka hana ʻana i nā mea ana pono e hōʻike i ka ikaika compressive kiʻekiʻe. ʻO kēia ikaika ka mea e hiki ai i ka granite ke pale i ke kaomi a me ka ikaika i hana ʻia i ka wā o ke ana ʻana me ka ʻole o ka warping a i ʻole ka pohā.

He 4.61×10⁻⁶/°C ka huina hoonui laina o ka granite, a ua emi iho ka nui o ka wai ma lalo o 0.13%. ʻO kēia mau waiwai i kūpono loa i ka granite no ka hana ʻana i nā papa ili pōhaku a me nā mea hana ʻē aʻe. ʻO ka ikaika compressive kiʻekiʻe a me ka haʻahaʻa wai haʻahaʻa e hōʻoia i ka mālama ʻana o ka mea i kona pololei a me ka maʻalahi i ka manawa, me ka liʻiliʻi o ka mālama ʻana.

Ka hopena

ʻO ka granite wale nō me nā waiwai kino kūpono—e like me ka paʻakikī, ka umekaumaha kikoʻī, a me ka ikaika compressive—hiki ke hoʻohana ʻia no ka hana ʻana i nā papa ili pōhaku kiʻekiʻe a me nā mea hana ana. He mea koʻikoʻi kēia mau mea no ka hōʻoia ʻana i ka pololei o ka wā lōʻihi, ka lōʻihi, a me ka hana maʻalahi o kāu mau mea ana. Ke koho ʻana i ka granite no ka hana ʻana i nā mea hana ana, he mea nui e hōʻoia i ka hoʻokō ʻana o ka mea maka i kēia mau kikoʻī koʻikoʻi.
