What Is Abrasive Material

Garnet abrasive is a kind of abrasive blasting material, composed of a garnet family of minerals, including aluminum sphalerite, red sphalerite, magnesium sulfide garnet, red garnet, and blue garnet. It is used as a non-toxic substitute for slag and silica sand. Although expensive, garnet abrasive is cost-effective because garnet has a Mohs hardness score of between 7 and 8, allowing recycling. It also has the benefit of low dust, keeping the spray area clean.

Garnet Abrasive Can Be Used For Both Wet And Dry Spraying

Blasting with garnet abrasive can be used for surface cleaning, coating removal, and water jet cutting, and since it is non-toxic, it is also used in Marine applications.

Garnet refers to the classification of crystal structure rather than chemical composition, which provides some variation of garnet abrasive composition. The mixture may be pink, reddish brown or grayish brown. Density between 135-150 LBS/ft.

The granular nature of abrasivo garnet can be used as an abrasive because it has a Mohs hardness of between 7 and 8. When fired at high speed, the garnet particles will clean the hard surface and prevent cracking, allowing the recovery of the garnet abrasive. A variety of particle sizes from coarse to fine are available for different applications.

The Key Advantages Of Garnet Abrasive

The key advantage of bulk garnet abrasive over silica sand or slag is occupational health. Silica exposure can lead to fatal and chronic damage in the form of silicosis. Slag, on the other hand, may contain trace amounts of toxic minerals. The end result of sandblasting with garnet abrasive is also very clean, with low dust and a lack of garnet particles embedded in the surface.

Although garnet abrasives are more expensive than other abrasives, their recyclability and clean sandblasting may reduce costs, making garnet abrasives potentially more cost-effective.

Abrasive garnet is particularly effective for:

• 1. Aluminum and glass fiber structure;
  

• 2. Bridges, docks, and shipyards;
  

• 3. Dusting and denim;
  

• 4. Industrial painting;
  

• 5. Hangar deck;
  

• 6. Need low dust confined space.
