Shanxi Black Granite The excellent characteristics of Shanxi black and the application of Shanxi black:
1. It has a good decorative effect and can be used for indoor and outdoor architectural decoration
2. Excellent processing performance: sawing, cutting, polishing, drilling, engraving, etc. Its processing accuracy can reach below 0.5μm, and its luminosity can reach above 1600. It can be used on the ground of roller skating rinks, monuments and inscriptions.
3. Good wear resistance, five to ten times higher than that of cast iron.
4. Small coefficient of thermal expansion, not easy to deform, similar to indium steel, slightly affected by temperature.
5. The modulus of elasticity is large, higher than that of cast iron.
6. Good rigidity, large internal damping coefficient, fifteen times larger than steel. It can be shockproof and shockproof.
7. Shanxi black is relatively brittle. When damaged, it will only fall off locally and will not affect the overall smoothness.
8. Shanxi black has stable chemical properties, is not easy to be weathered, and is resistant to acid, alkali and corrosive gases. Its chemical properties are proportional to the content of silicon dioxide, and its service life can reach about 200 years.
