I. Appearance Characteristics
The sesame black stone features a deep black base with a uniform distribution of fine, silver-gray crystals on the surface. These crystals act as a natural embellishment, bestowing the stone with unique textures and a sense of quality. Its appearance is dignified and sophisticated, neither monotonous nor lacking in elegance. It can blend seamlessly with various design styles such as modern minimalist, new Chinese, and European, adding a subtle sense of high-class to the space.
Section II: Physical Properties
- Hardness and Strength: The sesame black stone has a very high hardness, second only to China black, with compressive strength exceeding 200MPa. It can withstand frequent foot traffic and vehicle碾压, making it suitable for use in public places with heavy foot traffic.
- Wear and corrosion resistance: The stone surface is dense, highly wear-resistant, and boasts excellent resistance to acids and alkalis as well as weathering. Even when exposed to outdoor environments for extended periods, it maintains its appearance integrity and color stability.
- Water Absorption and Frost-Resistant Properties: Low water absorption rate, usually below 0.5%, which endows it with excellent frost-resistance, making it less prone to cracking or peeling in the cold northern regions during winter's repeated freeze-thaw cycles.
- Non-slip and easy maintenance: The surface treatment of the sesame black stone is diverse, including fire-blasted surface and litchi surface, offering good non-slip properties. It is also cost-effective to maintain, as it only requires a simple rinse with clean water to keep it clean.
