company news about The impact of different hardness levels of sandblasting media on materials

The impact of different hardness levels of sandblasting media on materials mainly manifests in the following aspects:

1. Surface Roughness:

   • Higher hardness media (such as alumina or silica sand) produce a coarser surface, suitable for applications requiring strong removal effects.
   • Softer media (such as glass beads or plastic pellets) leave a smoother surface, ideal for fine processing.

2. Removal Speed:

   • Harder media remove material faster during sandblasting, making them suitable for large-scale cleaning or coating removal.
   • Softer media have a slower removal rate, making them better for detailed surface treatment.

3. Material Damage:

   • Hard media may cause excessive wear or damage to softer materials.
   • Softer media generally cause less damage to most materials, making them suitable for processing delicate and sensitive materials.

4. Application Areas:

   • High hardness media are commonly used for metal surface treatment, rust removal, and old coating stripping.
   • Low hardness media are widely used for processing softer materials like plastics and glass, avoiding excessive damage.

Choosing the right sandblasting media should depend on the characteristics of the material being processed, the desired surface finish, and the required removal speed.
