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.
Propulsion of abrasives is done in two primary ways. In the first mechanism, pressurized fluid, that is, water or air is used. The second option makes use of a centrifugal wheel to propel the material. The first ever application of the technique was in the year 1870. During the same year, a patent was also filed by Benjamin Chew. Sand formed the main abrasive used at the time of invention. The use of sand has however dropped due to health concerns associated wit it.
Different variations have been made in the process of sandblasting because its applications have increased. Currently, the number of different types in use are very many. The major ones are, dry ice, automated, wet abrasive, bristle, hydro, micro-abrasive, bead, and wheel blasting. The nature of abrasive media is used to name some of the methods. All the types of blasting are suitable for different applications.
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.
