Sandblasting, also known as abrasive blasting (since more elements other than sand are used), is a process used to polish or smoothen a surface using a coarse grit ‘blasted’ through high pressure. Syntechnz.com says that to get the desired finish, there are various types of materials used for abrasive blasting, including steel, silicon dioxide, glass beads, and bristle.
Different techniques and methods are used for each type of grit to achieve the right finish. For example, to take the paint off a car before repainting it, you may use abrasive bead blasting since this method delicately removes the car’s paint without damaging the car’s metallic body.
Below are various sandblasting materials:
Also known as silica sand, quartz or silica, this refers to regular sand. Silicon dioxide is widely used to remove surface impurities. The sand particles are similar in size, and their edges are very sharp, making it suitable for abrasive blasting.
Bicarbonate of Soda
Soda or baking soda is used in sandblasting to remove rust without damaging the metal or causing depression to the surface. This grit is also used on delicate materials that might be damaged or break under more aggressive abrasives.
This is mainly used to remove rust and paint from steel metals. The grit leaves a smooth finish that makes it easy to polish the steel if needed.
This type of grid is used cabinets. The delicate glass material is used to polish the surface of a sandblasted object. With this grid, you can achieve a matte and satin finish
In the past, industry workers only ordinary sand was used for blasting and finishing surfaces; however, as advances are made in the metal industry, more options are used that leave better results. It all depends on the type of work, surface and finish you want to get.
