Advantages of calcined black sand louvre blades
Good grinding performance
- High hardness: calcined black sand has high hardness itself, which makes the louvre blades have strong cutting force when grinding, and can quickly remove the surface materials of the work-piece, such as rust, paint and burr on the metal surface, which can effectively shorten the processing time and improve the working efficiency.
- Excellent self-sharpening: During the sanding process, the abrasive particles will gradually fall off, and the new sharp particles are constantly exposed, so that the louvre blade can maintain good cutting performance for a long time, reduce the number of times of frequent replacement of abrasive tools, and improve the ability of continuous operation.
Strong physical properties
- Fast heat dissipation: Calcined black sand has good heat dissipation, when rotating at high speed, the heat generated can be emitted in time to reduce the temperature of the workpiece and the abrasive tool itself, reducing the risk of deformation of the workpiece, burns and damage to the abrasive tool due to overheating, which is conducive to prolonging the service life of the abrasive tool.
- Good elasticity: the louvre blade has strong elasticity and high tensile and flexural strength, which can withstand certain pressure and impact, and can better fit the surface of the workpiece when grinding, especially suitable for the grinding of complex shapes and curved surfaces.
- Low noise: the noise generated when working is small, can create a relatively quiet working environment, reduce the noise hazard to the operator.
Guaranteed quality
- Strong durability: after calcination treatment, the organizational structure of the black sand is more stable, and the wear-resistant property has been significantly improved, which makes the louvre blades able to withstand greater grinding pressure and friction, and is not easy to wear, with longer service life, and reduces the cost of frequent replacement of abrasive tools and downtime.
- High safety: the overall structure is firm, not easy to rupture, flying pieces and other dangerous situations in high-speed rotation, and does not damage the surface of the work-piece, to protect the safety of the operator and the quality of the work-piece.
- Wide material compatibility: it can be used for surface treatment of different materials such as stainless steel, metal, wood, furniture, stone, etc. It can meet the processing needs of many industries, such as automobile manufacturing, heavy machinery, ship repair, hardware and decorative industries.
- Various processing scenarios: it is suitable for work-pieces of various shapes and sizes, whether flat, curved or complex irregular surfaces, and can be effectively polished and shaped, descaled and polished.
