How Sandblasting Works: The Process Explained
The process of sandblasting involves three main components: an air compressor, a blasting pot, and an abrasive material. The air compressor generates high-pressure air that is then directed into the blasting pot. The blasting pot contains the abrasive material, which is propelled through a hose and nozzle by the compressed air.
When the operator activates the nozzle, a stream of abrasive particles is propelled onto the surface being treated. The force of the particles hitting the surface removes any unwanted materials or contaminants. The operator can control the pressure and angle of the nozzle to achieve the desired result.
There are different types of sandblasting equipment available, depending on the size and complexity of the project. Portable sandblasters are smaller and more maneuverable, making them suitable for smaller surfaces or hard-to-reach areas. Cabinet sandblasters are larger and enclosed, allowing for more precise control and containment of the abrasive material.
