Sandblasting or simply blasting is an composite term that refers to all processes that involve forcibly propelling an abrasive media onto a surface to clean or shape it. The force with which the abrasive is propelled determines the extent to which the required results are achieved. The process is achieved using a special machine called a sandblasting machine. When in need of best companies that offer services of sandblasting Los Angeles is the way to go.
The year 1870 was the first time blasting was being patented before the patent lost its legitimacy due to popularity of the process in later years. In a few years people had invented several version of the process for specific applications. Major versions are micro, dry ice, automatic, shot, and wet blasting. The paragraphs below discuss the variants that are widely adopted 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 as the name suggests, uses dry ice and air to blast a surface. Dry ice is applied at very high velocities on surfaces to dislodge contaminants. Adhesive forces are broken by the freezing effect produced by the frozen gas. No residue is left behind because the dry ice sublimes upon making impact.
Generally, the number of machines that can achieve the process has increased. Each machine varies in complexity, size, cost, and effectiveness. Commercial applications are achieved by huge units while minor home applications are done using hand-held versions of the machine.
