![]() ![]() In any case where hard or irregular objects can take flight from the high velocity of this equipment, adequate protection should be worn to protect operators from impact wounds. ![]() Sandblasters are used in many different settings, but there are a few precautions that must be taken when using these machines. Here are some other sandblasting uses to be aware of: Sandblasting is a cleaning process in which sand or gravel is propelled at high speeds for surface treatments Any media that has the potential to alter the surface of an object can be supersonically ejected into it, but sand-being both round and hard-is particularly suited for blasting large areas rapidly. Because sandblasting both removes material and imparts a unique finish to surfaces, much fine detail or intricate designs can be achieved in this way, often through the use of templates to guide the blasting.Ĭlick here to read our article on different uses of sandblasting Sandblasting is frequently used as an art form of graffiti removal. In this case, the lower part of the object, where it is less visible, can be "rough-blasted" with large abrasive particles to provide a key for the new paint or coating. Sandblasting is also used in the preparation of surfaces prior to painting - such as removal of old paint or rust - or to roughen a smooth surface, such as concrete, so that sprays or rollers can apply a better bond. Glass bead blasting is typically used for production work and therefore the glass beads are reused. The stream of beads impact the surface at high speed and scour it, removing dirt and other unwanted materials. This method uses a stream of very small glass beads propelled by compressed air. One of the most common alternatives to sandblasting is glass bead blasting or grit blasting. This method consists of propelling a stream of abrasive material via compressed air at a surface to smooth, roughen or otherwise modify it. There are several methods and tools that fall under the umbrella of sandblasting:įirst and foremost there is abrasive blasting. ![]()
