ʻO ke kala Granite a me ke koho ʻana o nā pōhaku no nā lako hana pololei ʻoihana.

Ma nā kahua o ke kūkulu ʻana a me ka ʻoihana, hoʻohana nui ʻia ka granite ma muli o kona paʻakikī, ka nui, ke kūpaʻa ʻana i ka waikawa a me ka alkali, a me ke kūpaʻa ʻana i ka wā. Eia kahi loiloi kikoʻī no ʻoe inā pili ke kala o ka granite i kona nui a pehea e koho ai i ka granite paʻa i ke kahua o nā lako hana pololei ʻoihana.
ʻO ka pilina ma waena o ke kala a me ka nui o ka granite
ʻO ka Granite ka mea nui i hana ʻia me nā minelala e like me ka quartz, feldspar a me ka mica, a ʻo kona kala e pili ana i nā ʻano a me ka nui o nā ʻāpana i loko. Mai ka manaʻo o ka nui, aia kahi pilina ma waena o ke kala a me ka nui, akā ʻaʻole ia he pilina pili pololei.

 

Nā ʻokoʻa o ka haku mele mineral: G kala māmāʻO ka ranite, e like me ke keʻokeʻo hina a me ka ʻulaʻula ʻiʻo, ua waiwai pinepine ia i ka quartz a me ka feldspar. He kiʻekiʻe a paʻa ka nui o kēia mau minelala ʻelua. ʻO ka nui o ka quartz mai 2.6 a 2.7g/cm³, ʻoiai ʻo ka feldspar e loli ana mai 2.5 a 2.8g/cm³ ma muli o ke ʻano. ʻO ka nui o ia mau minelala e alakaʻi ai i kahi ʻano piʻi i ka nui o ka granite māmā. ʻO ka granite ʻeleʻele, e like me ka ʻeleʻele a me ka ʻōmaʻomaʻo, loaʻa pinepine ka nui o ka hao a me nā minelala magnesium a me nā minelala ʻeleʻele e like me ka amphibole a me ka biotite. ʻO ka nui o ka amphibole ma kahi o 3.0-3.4g /cm³, a ʻo ka biotite ma kahi o 2.7-3.1g /cm³. Eia naʻe, i ka wā e loaʻa ai i ka granite ʻeleʻele nā ​​​​mea metala kaumaha (e like me ka hao a me ka manganese), e piʻi aʻe kona nui.

 

Ke kiʻekiʻe o ka crystallization a me ka mana hoʻonohonoho: Hiki i ke kala ke hōʻike i kekahi manawa i nā ʻokoʻa o ke kiʻekiʻe o ka crystallization a me ke ʻano o ka granite. ʻO ka Granite me ke kiʻekiʻe o ka crystallization a me ke ʻano paʻa he ʻano like a paʻa ke kala, a he kiʻekiʻe hoʻi kona density. ʻO kēia no ka mea ua hoʻonohonoho pono ʻia nā ʻāpana mineral a he nui ka nui o kēlā me kēia leo. ʻO ka Granite me ka crystallization maikaʻi ʻole a me ke ʻano wehe paha he mau kala mottled a ʻaʻohe like, he nui nā hakahaka i loko, a he haʻahaʻa ka density.
Koho ʻana i ka Granite ma ke kahua o nā lako hana pololei ʻoihana
Ma ke kahua o nā lako hana pololei ʻoihana, kiʻekiʻe loa nā koi kūpaʻa no ka granite. ʻO ka maʻamau, koho ʻia ka granite kūpono ma ka noʻonoʻo pono ʻana i nā kumu he nui:

ʻO ka haku mele a me ke ʻano o ka mineral: Makemake ʻia ka Granite me ka nui o ka ʻike a me ka hoʻolaha like ʻana o ka quartz a me ka feldspar. Loaʻa i kēia ʻano granite kahi ʻano kūloko paʻa, hiki ke hōʻemi pono i ka deformation i hoʻokumu ʻia e nā loli o ke kaumaha kūloko a hōʻoia i ka hana paʻa lōʻihi o nā lako. I kēia manawa, ʻo ka granite me ke kiʻekiʻe o ka crystallization, nā ʻāpana maikaʻi a like, a me ke ʻano paʻa ka koho makemake ʻia. I ka wā o ka hoʻohana lōʻihi a me ka hoʻopili ikaika, hiki iā ia ke mālama maikaʻi i ka pololei a hōʻemi i ka hopena o kāna mau loli kūkulu ponoʻī i ka pololei o nā lako.

Nā hōʻailona hana kino: Pono ka Granite e loaʻa i kahi helu omo wai haʻahaʻa, maʻamau ma lalo o 0.5%, e pale i nā pilikia e like me ka hoʻonui ʻana o ka nui a me ka hoʻemi ʻana o ka ikaika i hoʻokumu ʻia e ka omo wai, kahi e hoʻopilikia ai i ka pololei o nā lako. Pono e haʻahaʻa ke koina o ka hoʻonui wela. ʻO ke kūpono, pono e emi ma mua o 8 × 10⁻⁶/℃ e hōʻemi i nā loli dimensional i hoʻokumu ʻia e nā loli o ka mahana. Eia kekahi, pono e kiʻekiʻe ka ikaika compressive, maʻamau ma mua o 150MPa, e hōʻoia i hiki iā ia ke kū i nā ikaika like ʻole i ka wā o ka hana o nā lako.
ʻO nā ʻano maʻamau i ʻōlelo ʻia: Jinan Green Granite, Indian Black, South African Black a me nā granite ʻeleʻele ʻē aʻe, he ʻeleʻele ka hapa nui o ke kala, ʻano paʻa, he haʻahaʻa ka coefficient o ka hoʻonui wela a me ke kūpaʻa maikaʻi, a kūpono no nā kumu o nā lako nānā optical me nā koi kiʻekiʻe loa no ka pololei a me ke kūpaʻa. ʻO ka granite keʻokeʻo sesame, me ke kala māmā, nā ʻāpana mineral like, a me ka paʻakikī a me ka ikaika kiʻekiʻe, hoʻohana nui ʻia i nā lako hana chip uila a hiki ke hoʻokō i nā koi o ke kūlana kiʻekiʻe a me ka hana paʻa lōʻihi o nā lako.

I ka hopena, ʻoiai aia kekahi pilina ma waena o ke kala a me ka nui o ka granite, i ke koho ʻana i ka granite ma ke kahua o nā lako hana pololei ʻoihana, pono e noʻonoʻo pono i nā ʻano he nui e like me ka haku mele mineral, ka hoʻonohonoho ʻana, a me nā waiwai kino e hōʻoia i ka pololei kiʻekiʻe a me ke kūpaʻa o nā lako.
