All processes in which materials are used to clean or shape surfaces by propelling them are grouped under the umbrella term blasting. How fast the particles are propelled determine what results are achieved and to what extent. A sandblasting machine is the device used for this process. When one needs professionals in sandblasting Los Angeles has to be the place to prioritize.
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.
Wet blasting also offers the advantage of being able to eliminate dangerous materials like radioactive substance and asbestos without affecting the individual doing the job. Major formats in which it is available include walk-in booths, automated production machinery, total loss portable blasting units, and hand cabinets. The process also competes its dry counterpart in speed with which it can be done.
Wheel blasting is another variant. The wheel generates centrifugal force, which propels the abrasive against a surface. The name airless blasting operation is sometimes used to refer to this process due to lack of air or liquid. The types of abrasives that may be used include grit, steel shot, and cut-wire and the machine used in referred to the wheel machine. Power levels are set by adjusting the wheels and a single machine can have multiple wheels. Speed and efficiency of the wheel machine is set manually using controls incorporated on it.
Micro-abrasive blasting is sometimes referred to using the name pencil blasting. This variant makes use of tiny particles. Typical particles have a diameter of between 10 and 150 micrometers. The surface being blasted also has very small diameters, normally a few centimeters in diameter. The abrasive is delivered accurately to the surface in form of a stream. This process has to be done delicately because of its nature.
Dry ice blasting employs a combination of air and frozen carbon dioxide. The combination is propelled at extremely high speeds to dislodge surface contaminants. Bonds between the contaminants and the surface are dislodged by the freezing effect of dry ice. The resultant surface is clean without any kind of residue because of sublimation.
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.
