Application of green silicon carbide in grinding stone
1. Application supported by core material properties
High hardness and efficient cutting
Green silicon carbide has a Mohs hardness of 9.4, second only to diamond, and can quickly remove scratches and flaws on the surface of stone. It is especially suitable for rough and fine grinding of high-hardness stones such as marble and granite.
Wear resistance and stability
Its wear resistance is 11-20 times that of cast iron or rubber, ensuring that grinding tools (such as grinding wheels and grinding heads) maintain stable cutting performance during long-term use and reduce the frequency of replacement.
Thermal conductivity and thermal stability
Excellent thermal conductivity can quickly dissipate the heat generated by grinding, avoiding cracking or deformation of stone due to local high temperature.
2. Specific processing scenarios
Cutting and rough grinding
It is used for stone cutting and preliminary grinding, and high-hardness abrasives are used to efficiently remove excess materials and shorten the processing cycle. Fine polishing
Green silicon carbide powder (such as FEPA series and JIS series) can achieve mirror polishing of stone surface, and uniform particle size distribution ensures smooth and scratch-free surface after polishing.
Special-shaped stone processing
With tools such as sanding belts and grinding blocks, it is suitable for grinding carved stone or complex curved surfaces, and the edge shape enhances the ability to handle details.
3. Supporting tools and processes
Tool types
Green silicon carbide can be made into grinding wheels, sandpaper, grinding heads, oilstones and other tools to meet the needs of different processing stages (such as coarse-grained grinding wheels for rough grinding and micro-powder sandpaper for fine polishing).
Compound process
It is often used with coolant in stone processing to further improve the surface finish by reducing friction heat.
4. Summary of application advantages
Efficiency improvement: Self-sharpening reduces tool passivation and maintains continuous and efficient grinding.
Cost control: Long-life tools reduce consumable costs.
Quality Assurance: Chemical corrosion resistance avoids contamination of the stone surface and ensures the color and texture of the finished product.
The above application scenarios and characteristics jointly support green silicon carbide to become the core material in the field of stone grinding, especially suitable for high-precision and high-efficiency industrial stone processing needs.
