Te Karāhe Taiao me te Karāhe Horihori (Te Makanga Kohuke):
Ngā rerekētanga matua e whā me te aratohu ki te whiriwhiri i te huarahi hei karo i te poka:
1. Ngā Whakamāramatanga me ngā Mātāpono Whakatakotoranga
Karāhe Pango Taiao
Te Hanganga: I hangaia māoritia e te whakatioatatanga puhoi o te magma i roto i te hohonu o Papatūānuku'te kirinuku. He mea hanga te nuinga mai i te quartz, te feldspar, me te biotite, ā, i ahu mai te tae i ngā kohuke plagioclase pouri, i ngā kohuke pyroxene rānei.Ngā momo māngai: Haina Jinan mangu, Īnia mangu M10 (kiato 2.8-3.1g/cm³), ētahi atu karāneti (kiato 2.7-3g/cm³).
Granite Maka (Maka Kohuke)
Hanganga: He rauemi hangai i hangaia mā te whakaranu i te onepu kiripaka, te kapia, me ngā tae, kātahi ka whakarewaina i raro i te pāmahana teitei, i te pēhanga rānei hei whai i ngā tauira karāhe tūturu.
Te hanganga: 60–90% onepu kiripaka + kapia epoxy/polyester; kāore i te whai hanganga kohuke tūturu.
2. Te Whakataurite i ngā Āhuatanga Ā-tinana me ngā Āhuatanga Matū
| 属性 (Tauwhenua) | 天然黑花岗岩 (Natural Black Granite) | 人造花岗岩 (Maka Granite me te whakarewa kohuke) |
| 硬度 (Maama) | 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 (Atete Waikawa/Wakawa) | 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 (Taumautanga Ngawha) | 低膨胀率（4.6×10⁻⁶/℃） | 树脂在 >80℃ 时软化 |
3. Ngā Tono me te Tātari Utu
Karāhe Pango Taiao
Ngā Whakamahinga Pai:
Hanganga Tino Pai: Te whakakikorua o waho, ngā whakamaharatanga (hei tauira, ngā kōhatu urupā pango o Shanxi me te 110° kanapa).
Whakamahinga Ahumahi: Ngā turanga taputapu tino tika (he tino pumau te pāmahana).
Te utu: He nui te utu mō te kōhatu taratara (he pānga ki te momo me te hangarau tukatuka).
Granite Maka (Maka Kohuke)
Ngā Whakamahinga Pai:
Whakapaipai o roto: Ngā papa kaute utu-pai, ngā panera pakitara (ngā tauira ka taea te whakarite).
Ngā Hiahia Mama: Taonga whare, whakapaipai (30% mama ake).
Utu: Kāore te utu iti e pai mō ngā hua kotahi te whakaritenga (he nui te ōhanga whakaputa).
Te tiaki i te taiao me te oranga tonutanga.
4. Te Oranga Tonu me te Pānga ki te Taiao
Kohatu Taiao: He nui te kaha e pau ana i te keri engari ka taea te hangarua (hei tauira, te kuru hei kohatu); he iti noa te hihi (kua tohua he Akomanga A kua whakamanahia).
Kohatu Hanga: Ngā tukunga VOC i te wā e hangaia ana, engari ka taea te hangarua i ngā para; kāore he irahikotēnei.
