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.
The operator in wet blasting is also safe even from dangerous materials like radioactive substances and asbestos. Common formats in which the process can be done include walk-in booths, automated production machinery, hand cabinets, and total loss portable blasting units. The speeds under which this process can be done have increased making wet blasting compete dry blasting in this aspect.
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 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.
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.
