Sandblasting, also known as shot peening or sandblasting, is a destructive processing method for the surface of materials. It uses fine abrasive sand particles to impact the surface of the material, causing the surface to produce granular depressions to form a matte or eroded surface, thereby achieving the effects of removing rust, burrs, oxide layers, stress treatment, friction coefficient adjustment, precision adjustment, high adhesion, beautification, atomization, matting, and improving the smoothness of the surface of the material.
Abrasives used in sandblasting
Sandblasting is a versatile process that can utilize a variety of abrasives to achieve specific effects. The following is a list of commonly used materials in sandblasting:
Glass Beads: Great for precision work, polishing, and finishing fine surfaces without removing a lot of material.
Aluminum Oxide:A versatile abrasive suitable for general-purpose blasting and effective in removing rust, paint, and scale.
Silicon Carbide: A strong abrasive with a sharp edge used for bulk material removal, such as removing coatings and addressing corrosion issues.
Steel Shot: A strong abrasive with rounded steel particles used for removing heavy materials, strengthening surfaces, and creating compressive stresses.
Steel Grit: Angular steel particles suitable for aggressive material removal, often used for tasks such as removing heavy rust or scale from metal surfaces.
Plastic Media:A soft abrasive made from materials such as acrylic or urea used for gentle cleaning and surface preparation, especially of sensitive materials
Ceramic beads:Spherical beads made of zirconium oxide or aluminum oxide that provide a durable and consistent abrasive option for cleaning and blasting applications.
Garnet: Natural mineral abrasive for precision work and smooth results on a variety of surfaces.
Sandblasting Applications
Sandblasting is used in a wide variety of industries due to its versatility and ability to achieve different surface finishes. Here are some common applications for sandblasting:
Surface Preparation for Coatings
Sandblasting is widely used to prepare surfaces for coatings such as paint, powder coating or electroplating. It effectively removes contaminants, rust and old coatings, providing a clean, textured surface for improved adhesion.
Cleaning and Restoration
This process is used to clean and restore the surfaces of a variety of materials, including metal, wood and stone. Sandblasting can remove dirt, grime and unwanted layers without causing damage, making it ideal for restoring antiques or delicate items.
Deburring and Deburring
Shot peening is used for deburring and deburring during the manufacturing process. It helps remove sharp edges, burrs and excess material on machined or molded parts, ensuring a smoother, safer finished product.
Rust and Corrosion Removal
Sandblasting effectively removes rust and corrosion from metal surfaces, extending the life of equipment and structures. It provides a thorough cleaning, which is essential for maintenance and restoration projects.
Shot Peening Surfaces
Shot peening, using materials such as steel shot or glass beads, creates compressive stresses in the metal surface, increasing its fatigue resistance and overall strength. This is critical in aerospace, automotive and other industries where metal parts are subjected to cyclic loads.
Texturing and Etching
Sandblasting is used to create specific surface textures or etchings on materials such as glass, ceramics or metals. Sandblasting is often used in artistic or decorative applications to achieve unique and aesthetically pleasing designs.
Mold and Tool Cleaning
In the manufacturing industry, shot peening is used to clean molds, dies and tools by removing residues, deposits and contaminants. This helps maintain the quality and precision of the manufacturing process.
Composite Preparation
Shot peening is used to prepare composites for bonding or painting. It removes release agents and contaminants and provides surface profile to improve bonding.
