ʻO Granite Kūlohelohe vs ʻO ka granite artificial (Mineral Casting):
ʻEhā mau ʻokoʻa kumu a me kahi alakaʻi i ke koho ʻana i ka pale lua:
1. Wehewehe a me na Kumu Hookumu
Granite ʻeleʻele maoli
Hana ʻia: Hana ʻia ma ke ʻano ma muli o ka hoʻoheheʻe lohi ʻana o ka pelemaka i loko o ka Honua's ʻōpala. Hoʻokumu nui ʻia me ka quartz, feldspar, a me ka biotite, me ke kala i loaʻa mai ka plagioclase ʻeleʻele a i ʻole nā mineral pyroxene.Nā ʻano like ʻole: Kina Jinan ʻeleʻele, India ʻeleʻele M10 (density 2.8-3.1g/cm³), ʻē aʻe granite (density 2.7-3g/cm³).
ʻO ka Granite hoʻolei (Mineral Casting)
Hana ʻia: He mea synthetic i hana ʻia e ka hui ʻana i ke one quartz, resin, a me nā puaʻa, a laila hoʻoheheʻe ʻia ma lalo o ka wela kiʻekiʻe a i ʻole ke kaomi ʻana e hoʻohālike i nā kumu pōhaku maoli.
Huina: 60–90% quartz one + epoxy/polyester resin; nele i nā hale mineral maoli.
2. Hoʻohālikelike ʻano kino a me kemika
| 属性 (Waiwai) | 天然黑花岗岩 (Natural Black Granite) | 人造花岗岩 |
| 硬度 (Paʻakikī) | 莫氏硬度 6–7，抗压强度 ≥200 MPa | 莫氏硬度 4–5，抗压强度 80–120 MPa |
| 密度 (Density) | 2.63–3.1 g/cm³（高密度） | 2.2–2.5 g/cm³（轻质） |
| 酸/碱抗性 (Paʻa ʻAkika/Alkali) | 高度抗腐蚀（HCl中无腐蚀） | 树脂在强酸/溶剂中降解 |
| 吸水率 (Water Absorption) | ≤0.2%（适合户外使用） | 0.5–1.2%（需防水处理） |
| 热稳定性 | 低膨胀率（4.6×10⁻⁶/℃） | 树脂在 >80℃ 时软化 |
3. Nā noi a me ka nānā ʻana i ke kumukūʻai
Granite ʻeleʻele maoli
Nā hoʻohana kūpono:
ʻO ke kūkulu ʻokoʻa: ʻO nā pale o waho, nā monuments (e laʻa, nā pōhaku kupapaʻu ʻo Shanxi ʻeleʻele me 110° ʻōlinolino).
Hoʻohana ʻOihana: Nā kumu lako pono (ʻoi aku ka paʻa wela).
Kumukūʻai: He kiʻekiʻe ke kumu kūʻai o ka pōhaku ʻala (pili ʻia e nā ʻano ʻenehana a me ka ʻenehana hana).
ʻO ka Granite hoʻolei (Mineral Casting)
Nā hoʻohana kūpono:
ʻO loko o ka hale: ʻO nā pākuʻi kūʻai kūʻai, nā pā pā (nā kumu hoʻohālikelike).
Pono Māmā: Lako, ʻoki hoʻonani (30% māmā).
Kumukūʻai: ʻAʻole kūpono ke kumu kūʻai haʻahaʻa no nā huahana kikoʻī hoʻokahi (hoʻokele waiwai kiʻekiʻe).
Ka palekana a me ka hoʻomau.
4. Hoʻomau a me ka hopena o ke kaiapuni
Pōhaku Kūlohelohe: ʻO ka hoʻohana ʻana i ka ikehu eli kiʻekiʻe akā hiki ke hoʻohana hou ʻia (e laʻa, ʻoki ʻia e like me ka hui); liʻiliʻi liʻiliʻi (koho i ka Papa A i hōʻoia ʻia).
Pōhaku Synthetic: Hoʻokuʻu ʻia ka VOC i ka wā hana, akā hiki ke hoʻohana hou ʻia ka ʻōpala; ʻaʻohe radioactivkeia.
