Description

Technical Field

[0002] Crystal brick, this term sounds attractive, but in fact in the building materials or decoration materials industry, there is no material directly and widely called "crystal brick". However, literally speaking, it may refer to ceramic tiles or glass bricks with crystal-like transparency or glossy effects.

[0003] Crystal bricks or ceramic tiles and glass bricks with crystal-like appearance may use sandblasting technology in the production process to achieve specific decorative or functional effects. Sandblasting is a surface treatment technology that uses high-speed jet abrasive particles (such as corundum, quartz sand or other special abrasives) to impact the surface of the material, thereby changing its surface texture, glossiness or engraving patterns. For some special applications, such as crystal bricks that require light to pass through or visual effects to penetrate (such as partition walls, luminous floors, etc.), it may be necessary to sandblast both sides so that light can penetrate better and show unique visual effects.
