ʻO kekahi mau kuhi hewa i ka mālama ʻana i ke kumu moe granite

Me ka ulu wikiwiki o ka ʻoihana, ua hoʻohana nui ʻia nā papa moena marble. Ma hope o nā miliona makahiki o ka ʻelemakule, loaʻa iā lākou kahi ʻano like ʻole, kūpaʻa maikaʻi, ikaika, paʻakikī kiʻekiʻe, a me ka pololei kiʻekiʻe, hiki ke paʻa i nā mea kaumaha. Hoʻohana nui ʻia lākou i ka hana ʻoihana a me ke ana ʻana o ke keʻena. No laila, he aha nā hewa maʻamau i ka mālama ʻana i nā papa moe marble? Aia ma lalo kahi wehewehe kikoʻī.

1. Holoi me ka wai

ʻO nā papa moena marble, e like me ka lāʻau maoli a me ka pōhaku maoli, he mau mea porous e hiki ke hanu a i ʻole e komo wale i ka wai a hoʻoheheʻe i nā mea haumia ma ka hoʻoinu ʻana. Inā komo ka pōhaku i ka wai nui a me nā mea haumia, hiki ke hoʻomohala ʻia nā pōʻino pōhaku like ʻole, e like me ka melemele, ka lana ʻana, ka ʻōpala, ka pohā, ka keʻokeʻo, ka hoʻoheheʻe ʻana, nā kiko wai, efflorescence, a me ka hoʻopau matte.

2. Hōʻalo i ka pilina me nā mea kūʻole

Pili nā pōhaku a pau i ka waika a me ka alkali. No ka laʻana, ʻo ka waika ka mea e hoʻoheheʻe pinepine ai i ka granite, e hopena i kahi hiʻohiʻona melemele ma muli o ka pyrite oxidation. ʻO ka ʻakika hoʻi ke kumu o ka ʻinoʻino, kahi e hoʻokaʻawale ai i ka calcium carbonate i loko o ke kinikini a hoʻokaʻawale i ka ʻili i nā palena palaoa o ka alkaline feldspar a me ka quartz silicide. 3. E pale i ka uhi ʻana i nā papa moena me nā ʻōpala no nā manawa lōʻihi.
I mea e paʻa ai ka hanu ʻana o ka pōhaku, e pale i ka uhi ʻia ʻana o ia me ka ʻōpala a me nā ʻōpala, no ka mea e pale ana kēia i ka hoʻoheheʻe ʻana o ka wai ma lalo o ka pōhaku. E pilikia ka pōhaku i ka huhū ma muli o ka wai. Hiki i ka hoʻonui ʻia ʻana o ka makū ke alakaʻi i ka huhū. Inā pono ʻoe e waiho i ke kapena a i ʻole ka ʻōpala, e hoʻomaʻemaʻe pono. E hoʻohana mau i ka ʻohi lepo a me ka traction electrostatic no ka wehe ʻana a me ka hoʻomaʻemaʻe ʻana i ka lepo, inā e hana ana me ka granite paʻa a i ʻole ke kinikini palupalu.
