Sandblasting is also called abrasive blasting because it involves high pressure propulsion of abrasive material against surfaces. This is normally done with one of the four intentions, that is, roughening smooth surfaces, smoothening rough surfaces, shaping surfaces, and removing contaminants from a surface. The pressure in the stream of abrasive determines what it can do. For elegant sandblasting Los Angeles is the right place to pay a visit.
There are two main mechanisms through which the abrasive is propelled. The first method involves use of pressurized fluid, which can be air or water. The second mechanism involves the use of a centrifugal wheel to push the abrasive media. The first application of this process was in 1870. It was also patented the same year by Benjamin Chew Tilghman. At the time of patenting, sand was the main abrasive media in use, but that has changed since.
With everyday that the uses of sandblasting increase, people continue coming up with different ways of achieving the process. Currently, types of blasting in application are numerous. Among them are, dry ice, hydro, micro-abrasive, automated, bristle, bead, wheel, and wet abrasive blasting. Some methods are named after the abrasive they use. Not all the methods can be used for the same application. Some are more suited for certain uses than others.
Wet abrasive blasting uses abrasives that have been made wet through addition of water or other liquids. Fine-textured media is normally used for the process. The media can be of any material such as steel, glass, plastic, wood, and stone. Most contaminants are removed effectively by this method. Some among the surface contaminants that can be removed using this method are grease, oil, graffiti, dust, asbestos, radioactive material, old paint, and mold among others. This is partly due to the fact that the cleaning ability of abrasives is enhanced by adding water and cleaning agents.
Wet abrasive blasting offers many advantages that cannot be found in dry media blasting. First, it can be done using any of the many device formats available. The types of device formats available include total loss portable units, walk-in booths, hand cabinets, and automated production machinery. The process can also be done in the same time frame as conventional dry sand blasting.
Main advantage of wet blasting is surface protection it provides which keep surfaces intact after the process. There is formation of a lubricating cushion between substrates and abrasives by fluids. The cushion reduces the impact of the propelled material. Additionally, media breakdown is much lower plus surfaces are not impregnated with foreign materials.
Dry media processing results in dust clinging onto the surface because of static energy. This does not happen in wet blasting because the surface is discharged of all static energy by the liquid. Since there is no surface contamination resulting from use of wet media, different abrasive materials can be used in the same machine.
The levels of cleanliness achieved through use of wet materials makes the process to be more preferred for use in surface preparation. Surfaces can be prepared for bonding or coating operation using blasting. The resultant surfaces are normally very clean and improve the strength of the bond formed.
