Blasting is an umbrella term referring to processes that involve propelling abrasives against surfaces to clean or shape them. The degree of results is dependent on the force of propulsion. The machine used is called a sandblasting device. When in need for service providers of services of sandblasting Los Angeles should be prioritized.
The process was first patented in 1870, but since that time, it has evolved and become a common practice. In fact, several variants of the process have been developed to suit various applications. Some major variants include sodablasting, shot, wet, bead, dry ice, hydro, automated, and wheel blasting among many others. This article will discuss the major variants of the process that are in common use today.
Wet blasting was pioneered by someone called Norman Ashworth because of the advantages it offered over its sand counterpart. Sand blasting had been banned by many countries at that time because of the health issues associated with it. Wet blasting allows the use of media of a wide range of densities including plastic and steel. It also removes grease while blasting at the same time. Water helps to wet silicacious materials making their use safe.
Another advantage of wet blasting is the ability to remove dangerous materials like asbestos and radioactive elements without causing harm to the operator of the machine. It is also available in major formats like walk-in booths, total loss portable blasting units, hand cabinets, and automated production machinery. The process can also be done at high speeds comparable to those of its dry counterpart.
Wheel blasting forms the other variant. The particles propelled against surfaces are forced by centrifugal force created by the wheel. There is no air or liquid used, which makes the version to sometimes be referred to as airless blasting operation. Steel shot, cut-wire, and grit are some of the abrasives used. The device used is called a wheel machine. The number of wheels varies by the device models and power depends on the number of wheels a device has. The level of efficiency and speed are set on the device.
Micro-abrasive blasting is also called pencil blasting. This variant uses very small abrasives of between 10 micrometers to 150 micrometers. The surface area to be blasted is usually very small in the range of one square millimeter. The abrasive is delivered accurately in a fine stream using high levels of pressure. The stream is normally delicate enough to be able to write on an eggshell.
In dry ice blasting as suggested by the name, frozen carbon dioxide and air are used in the process. Dry ice dislodges surface contaminants by being propelled at very high speeds on surfaces. The freezing effect of dry ice helps to dislodge and break bonds between surfaces and dirt. Sublimation ensures that no surface residue forms afterward.
Generally, there are several machines that are used to achieve this process. They vary in size, complexity, efficiency, and cost among other factors. Large machines are meant for doing the activity on a commercial scale while the small ones are for private use in most cases.
