Pretreatment Steel Grit

1. Surface treatment of transportation vehicles such as automobiles, railways, ships, and airplanes, including anti-corrosion protection and decoration.

2. Surface treatment of mechanical equipment, including cleaning, rust removal and improvement of surface finish.

3. Surface treatment of steel structures, including anti-corrosion protection and surface treatment of bridges, buildings, workshops, etc.

4. Surface treatment of pipelines and containers, including anti-corrosion protection and surface treatment of pipelines and storage tanks in petroleum, chemical, food and other industries.

5. Surface treatment of steel products, including anticorrosion, spraying and surface treatment of steel, castings, forgings and other products.

High hardness: With the characteristics of high carbon steel, it has high hardness, can effectively cut and clean the metal surface, and ensure the uniformity and quality of the surface treatment effect.

Wear resistance: Due to the production of high carbon steel, it has strong wear resistance, which can maintain the shape and sharpness of the particles during use and improve the service life.

Appropriate Particle Size: Particle size is usually selected according to specific application needs and can be suitable for different types and sizes of metal surface preparation.

Recyclable: Under the right conditions, Pretreatment steel grit can be cleaned and screened for recycling, reducing costs and environmental impact.

First, understand the material type of the metal surface to be treated (such as steel, aluminum alloy, etc.) and the surface treatment requirements (removal of oxide layer, rust removal, cleaning, etc.). Different metals and processing requirements may require different types and sizes of steel shot.

Its grain size is usually expressed in grain size, which usually ranges from G10 to G120. Coarser grits (such as G10-G40) are suitable for larger surface preparation tasks, while finer grits (such as G80-G120) are suitable for finer handling and coating preparation. Choosing the right particle size depends on the roughness of the metal surface and the processing requirements.

Pretreatment steel grit is divided into different grades according to hardness, such as GP (general hardness), GL (low carbon hardness) and GH (high carbon hardness). Harder steel shot can provide higher detergency, but may cause surface damage in some cases. Therefore, choose the appropriate hardness level according to the specific processing requirements and the hardness of the surface material.

Taking into account the use of its technology and equipment, such as sandblasting models, pressure and speed, etc., to ensure the fluidity and adaptability of the steel shot in the process.

When choosing, economy and environmental protection should also be considered. Some steel shot may have a long life and be recyclable, resulting in lower disposal costs and less waste.
