Application of black silicon carbide in stone blasting:
1，Removing surface materials: The high hardness of black silicon carbide makes it easy to remove materials from the surface of the stone, whether it is marble or granite and other hard stones, it can achieve the ideal removal effect. In the process of stone processing, it is often necessary to remove stains, scratches or uneven parts on the surface. Black silicon carbide sandblasting can quickly complete these tasks and improve the processing efficiency of the stone.
2，Increasing surface roughness: Through black silicon carbide sandblasting, the surface of the stone can become rougher, which helps to increase the adhesion between the stone and the adhesive or other materials.
3，Achieving matte effect: After black silicon carbide sandblasting, the surface of the stone will present a matte effect, which is more beautiful and practical in some occasions. The matte effect of the stone surface can reduce reflection and glare, reduce visual interference, and improve the comfort of use.,
III. Precautions for black silicon carbide blasting
—Choose the appropriate particle size: According to the hardness and processing requirements of the stone, choose the appropriate black silicon carbide particle size. Too large particles may cause excessive wear on the stone surface, and too small particles may not achieve the ideal removal effect.
—Control the sandblasting intensity: The size of the sandblasting intensity directly affects the removal effect and roughness of the stone surface.
