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.
Abrasive is propelled through two major means. The first mechanism uses pressurized fluid, in which case water or air can be used. The second mechanism uses a centrifugal wheel for propulsion of abrasive media. This process was first applied in 1870. The first patenting was also done by Benjamin Chew Tilghman in the same year. When it was being patented for the first time, the main abrasive material in use was sand although other materials have been adopted over the years.
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.
In wet abrasive sandblasting, water or other liquids are added into the abrasives before they are used. Normally fine-textured media is used. Material of media used can be anything including stone, wood, steel, plastic, and glass. Most surface contaminants are effectively eliminated using this method. Grease, radioactive material, oil, graffiti, dust, old paint, mold, and asbestos are among contaminants that can be removed well. Cleaning agents and water added in the process is part of the reason why the method is very effective.
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 benefit of using wet blasting is that surfaces remain intact after the process because they are protected. A lubricating cushion is created between the substrate and abrasive by the fluid. Therefore, the impact of the propulsion is reduced a lot. Additionally, the level of media breakdown is low and foreign materials do not get impregnated into the surface.
Use of dry media processing results into static forces which cause dust particles to cling onto surfaces. This never happens with wet blasting because the surface gets discharged of all static forces by the liquid. Also, a single equipment can work with more than one abrasive material without concern for contamination.
Use of wet materials results into high levels of cleanliness in surfaces. This makes it preferable for use in preparing surfaces for bonding or coating operations. The bond strength that results after cleaning surfaces with this method is normally very high.
