Choosing the Right Abrasive Sand

Choosing the right abrasive sand depends on the characteristics of the surface to be used, the cleaning or roughening requirements, and the intended use. Here are some factors to consider when choosing the right abrasive grit:

1. Surface Material: First, you must determine the material of the surface to be sandblasted. Different materials such as metal, wood, glass or stone have different abrasive properties and may need to be treated with different abrasive grits.

2. Degree of Cleanliness or Roughness: The degree of cleanliness or roughening you need is an important factor in choosing abrasive grit. Finer grit sizes have lower abrasive power, while coarser grit sizes provide more intense abrasiveness.

3. Abrasive Power: The abrasive power of the blasting sand is another factor that you should consider in the selection. For example, materials such as aluminum oxide or steel granules have higher abrasive power, while silica sand is less abrasive.

4. Size and Shape: The grain size and shape of the abrasive sand are also important. Different grain sizes can produce different roughening effects. Coarse grits provide a faster abrasion, while fine grains provide a softer roughening.

5. Application Technique: The equipment and application techniques you will use for the sandblasting process are also effective in the selection. Different application methods using compressed air, turbine engines or water jets may require a particular type of abrasive grit to be more suitable.

6. Environmental Impacts: You should also consider the environmental impact of abrasive sand. Some blasting sands can be harmful to the environment or pose health risks. Therefore, it is important to choose materials that are more environmentally friendly or safer for health, taking into account environmental factors.

To select the right abrasive grit, it is important to consider the characteristics of the surface, cleaning or roughening requirements, and application conditions. If you are undecided, it may be helpful to consult an expert or a company that supplies sandblasting materials.
