History 

The history of abrasive blasting dates back to the late 1800s when the technique was first used in the United States for cleaning the exterior of buildings. However, it wasn't until the early 1900s that abrasive blasting was used for industrial purposes such as surface preparation and cleaning of metal surfaces.

The first abrasive blasting equipment was invented in 1870 by Benjamin Tilghman, a United States Navy engineer. Tilghman's invention used sand as the abrasive material and compressed air to propel the sand onto a surface. In the early 1900s, various abrasive materials such as steel shot and aluminum oxide were introduced, which expanded the range of applications for abrasive blasting.

During World War I, abrasive blasting became widely used for the repair and maintenance of ships and aircraft. After the war, the technique continued to be used in the automotive and manufacturing industries for surface preparation and cleaning.

In the 1930s, automated abrasive blasting machines were developed, which allowed for faster and more efficient surface preparation. By the 1950s, abrasive blasting had become a widely accepted industrial process, and today it is an integral part of many industries, including construction, manufacturing, automotive, and aerospace.

Over the years, improvements have been made to the equipment and techniques used in abrasive blasting to increase efficiency, reduce dust emissions, and improve safety. Today, abrasive blasting is used in a wide range of applications, including cleaning and surface preparation, removal of coatings and corrosion, etching and carving, and finishing and texturing.

Types of Abrasive Blasting

Wet Abrasive Blasting

Wet abrasive blasting, also known as vapor abrasive blasting or slurry blasting, is a type of abrasive blasting where water is used as a medium to mix and propel the abrasive material onto a surface. The water helps to reduce the amount of dust and debris generated during the blasting process, making it a safer and more environmentally friendly option than dry blasting.

In wet abrasive blasting, a mixture of water and abrasive material is pressurized and propelled onto the surface using specialized equipment. The water helps to control the flow and velocity of the abrasive material, allowing for more precise and uniform cleaning or surface preparation. The water also acts as a lubricant, reducing the wear and tear on the blasting equipment and prolonging its lifespan.

Wet abrasive blasting is commonly used for surface preparation and cleaning of delicate or sensitive surfaces, such as historic buildings, monuments, and sculptures. It is also used in the automotive industry for the removal of paint and rust from car bodies and parts.

One advantage of wet abrasive blasting is that it can be used with a wide variety of abrasive materials, including glass beads, garnet, aluminum oxide, and steel shot. The use of water as a medium also reduces the amount of abrasive material needed for the job, which can save money and reduce waste.

Overall, wet abrasive blasting is a safe and effective alternative to dry blasting, providing a more controlled and efficient method of surface preparation and cleaning.

Dry Abrasive Blasting

Dry abrasive blasting, also known as dry blasting, is a type of abrasive blasting where compressed air or other gas is used to propel dry abrasive materials onto a surface. The dry abrasive material is usually selected based on the specific application and can include materials such as sand, glass beads, aluminum oxide, or steel shot.

In dry abrasive blasting, the abrasive material is propelled at high velocity onto the surface being treated, which helps to remove coatings, corrosion, or other surface contaminants.
