What are the steps to perform Sandblasting?
Firstly, sand is poured into the chamber of the sandblasting machine. The sandblasting machine is then attached or connected to an air compressor. The machine is then turned on and sand is propelled out through a handheld nozzle. The pressure of the sand can vary from anything between 50 to 130 PSI (Pounds per square inch). Sand has abrasive properties hence when it is blasted on a rough surface with flaws, it smoothens it out. Not just metal surfaces, but concrete is also sandblasted. Sandblasting eradicates the excess material making the surface smoother.
What does SandBlasting mean?
Sandblasting is also commonly known as an abrasive blasting technique to smoothen out metal surfaces. It involves the use of a powered machine and is a surface finishing process. Spraying abrasive particles using high pressure is known as sandblasting. It literally blasts surfaces with sand particles. This process results in a smooth and even-textured surface. This is achieved due to the force and pressure with which the sand particles strike the metal surface. The gritty texture of the sand is what wears away excess material from the surface of the metal. It practically is a larger and advanced form of sandpaper devised into a machine with high pressure. Sandpapers are used to smoothen out mirrors, similarly, metal surfaces are smoothened using Sandblasters.
What is the most important component of sandblasting?
Let’s move on now to the most important component of sandblasting: the media itself. There are lots of variables in sandblasting media to give users plenty of options to choose from.
How do air and media travel in a sandblaster?
The air and media travel through the blast hose and out of a nozzle. At this point, they are inside the sandblasting chamber, whether that is a small compartment or an entire room, and usually come out the nozzle of a handheld gun. The particles travel at high velocities and impact the object, stripping it of whatever is on its surface. Depending on the size, texture and density of the particles, they will also leave tiny divots in the material. These divots allow future coatings to adhere to the object’s surface.
