I. Appearance Features
The芝麻black stone features a deep black base with uniformly distributed silver-gray fine crystals on its surface. These crystals serve as a natural embellishment, bestowing the stone with unique textures and a refined feel. Its appearance is dignified yet elegant, neither monotonous nor lacking in charm. It seamlessly blends with a variety of design styles, including modern minimalist, contemporary Chinese, and European, adding a subtle sense of sophistication to the space.
II. Physical Properties
- Hardness and Strength: The sesame black stone has an extremely high hardness, second only to Chinese black stone, 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 exhibits excellent resistance to acids and alkalis as well as weathering. Even after long-term exposure to outdoor environments, it maintains its integrity and color stability.
- Water Absorption & Frost-Resistant: Low water absorption rate, typically below 0.5%, endowing it with excellent frost-resistance. In cold northern regions, it is less prone to cracking or peeling even after repeated freezing and thawing during winter.
- Non-slip and easy maintenance: The surface processing of sesame black stone is diverse, including fire-burnt surface and lichee surface, offering excellent non-slip properties, and with low daily maintenance costs, simply rinsing with clean water is sufficient to keep it clean.
