Catalogue

Abrasive sandblasting technology is an advanced technology that uses high-speed jet abrasives to grind the surface of objects and remove pollutants. By spraying abrasives onto the surface of objects in a high-speed airflow, abrasive blasting technology can achieve efficient and uniform surface treatment, and is widely used in the processing and treatment of different materials, including metals, plastics, ceramics, etc.

Advantages of Sandblasting

1. Fast and effective

It can quickly remove stains, old paint, rust, etc. on the surface of objects, and achieve the ideal surface effect in a short time.

2. Multi-material application

Applied to the surface treatment of various materials, including metal, plastic, wood, stone, etc., with strong adaptability.

3. Flexible control

Flexible control of the treatment effect can be achieved by adjusting parameters such as sandblasting pressure, abrasive selection, sandblasting distance and time, and adapting to different needs and materials.

4. Good surface effect

It can form uniform wear on the surface of the object, improve the surface smoothness and texture, and achieve the ideal surface effect.

5. No pollution

No chemical agents and solvents are used in the process, no pollutants and harmful gasses are produced, and it is environmentally friendly.

 Disadvantages of Sandblasting

1. Noise and dust

The process will generate noise and a large amount of dust, which may cause pollution and health risks to the operator and the environment.

2. Surface damage

It may cause mechanical damage to the surface of the object, such as scratches, deformation, etc., and it is necessary to control the sandblasting parameters to avoid damage.

3. Some materials are not applicable

Certain materials, such as brittle materials such as glass and ceramics, may not be suitable for blasting and are prone to breakage or particle residue.

4. Health and Safety Risks

Dust generated during the process may cause damage to the operator’s respiratory system and requires appropriate protective measures.

5. Higher cost

The cost of equipment and abrasives is relatively high, and a certain amount of equipment and abrasives needs to be invested.

6. Difficulty in operation

Depending on the material and finish, different abrasive selections and adjustments may be required.

Conclusion

Sand blasting is a common surface treatment technique with a wide range of applications in many different fields. From metal processing, car repair, ship repair to stone carving, furniture renovation, etc., sandblasting can effectively remove surface dirt, oxide layer, coating, etc., and improve the surface roughness, gloss and adhesion of objects. However, sandblasting also has some limitations, such as possible adverse effects such as dust, noise and vibration, and may pose potential risks to the environment and health. Therefore, when performing sandblasting operations, the corresponding operating procedures and safety measures should be followed to ensure the safety of the operator and the environment. With the continuous development and improvement of technology, sandblasting technology may continue to evolve in the future to better meet the needs of different industries for surface treatment.

What is Abrasive Grain Technology? 5 Key Points Explained | VSM Grinding Technology Knowledge Base

It is crucial to select the appropriate abrasive mineral for each material during the grinding process. This not only prevents surface damage but also enhances the efficiency of the grinding operation, minimizing the overall time required. However, these minerals in abrasive grain technology do not possess the same hardness, leading to variations in their performance during grinding operations. Apart from structural differences, each mineral also exhibits unique characteristics, such as resistance to scratching, impact, and self-sharpening.
