Natural Granite vs Artificial granite (Mineral Casting):
Misiyano ina yakakosha uye gwara rekusarudza kwekudzivirira gomba:
1. Tsanangudzo uye Maumbirwo Misimboti
Natural Black Granite
Maumbirwo: Zvakangogadzirwa nekunonoka kupenya kwe magma mukati mePasi's crust. Yakagadzirwa kunyanya yequartz, feldspar, uye biotite, ine ruvara rwakatorwa kubva kune yakasviba plagioclase kana pyroxene zvicherwa.Anomiririra marudzi: China Jinan dema, India dema M10 (density 2.8-3.1g/cm³), imwe granite (density 2.7-3g/cm³).
Kanda Granite (Mineral Casting)
Kuumbwa: Chinhu chekugadzira chinogadzirwa nekusanganisa jecha requartz, resin, uye pigment, ndokuzoumbwa pasi pekushisa kwepamusoro kana kumanikidzwa kutevedzera echisikigo granite mapatani.
Kuumbwa: 60-90% quartz jecha + epoxy / polyester resin; inoshaya maumbirwo emaminerari echisikigo.
2. Physical uye Chemical Properties Kuenzanisa
| 属性 (Property) | 天然黑花岗岩 (Natural Black Granite) | 人造花岗岩 (Cast Granite & mineral casting) |
| 硬度 (Kuoma) | 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 (Acid/Alkali Resistance) | 高度抗腐蚀(HCl中无腐蚀） | 树脂在强酸/溶剂中降解 |
| 吸水率 (Kunyura kweMvura) | ≤0.2% (适合户外使用） | 0.5–1.2% (需防水处理） |
| 热稳定性 (Thermal Stability) | 低膨胀率(4.6×10⁻⁶/℃） | 树脂在 >80℃ 时软化 |
3. Applications and Cost Analysis
Natural Black Granite
Ideal Uses:
Kuvaka Kwekutanga: Kuvharirwa kwekunze, zviyeuchidzo (semuenzaniso, Shanxi Black tombstones ane 110° kupenya).
Kushandiswa Kweindasitiri: Precision midziyo mabhesi (yepamusoro kupisa kugadzikana).
Mutengo: Mutengo wedombo rakashata wakanyanya kukwirira (unokonzerwa nemhando dzakasiyana uye tekinoroji yekugadzirisa).
Kanda Granite (Mineral Casting)
Ideal Uses:
Indoor Décor: Matafura-anodhura-anoshanda, mapaneru emadziro (maitiro anogoneka).
Chinorema Chinodiwa: Fenicha, yekushongedza trim (30% yakareruka).
Mutengo: Mutengo wakaderera haukodzere zvigadzirwa zvemhando imwe chete (yepamusoro hupfumi hwekugadzira).
Kuchengetedza kwezvakatipoteredza uye kuenderera mberi.
4. Sustainability uye Environmental Impact
Natural Stone: High migodhi simba kushandiswa asi recyclable (semuenzaniso, akapwanyika aggregate); mashoma radiation (sarudza Kirasi A yakasimbiswa).
Synthetic Dombo: VOC emissions panguva yekugadzirwa, asi tsvina inodzokororwa; hapana radioactivity.
