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.
Increased applications of sandblasting made it possible for variations to be introduced. Currently there are several types in use for different purposes. The major types are, wet abrasive, bead, wheel, dry ice, automated, bristle, hydro, and micro-abrasive blasting. Some of the methods are named according to the nature of abrasive media they use. Each type of blasting is uniquely suited for a specific application.
In wet abrasive blasting as suggested in the name, the abrasive used is normally made wet by adding water or other liquids. The media used normally has a fine texture and can be anything ranging from steel to plastic. This method is very effective at removing most contaminants from surfaces especially grease, oil, radioactive material, graffiti, dust, asbestos, mold, and old paint. This is because cleaning agents and water are added to improve and speed the cleaning ability of abrasives.
When compared with dry media blasting, wet abrasive blasting has far too many advantages. First, any among the device formats currently available can be used to perform it. Main device formats available are walk-in booths, hand cabinets, automated production machinery, and total loss portable units. The length of time required to complete it is the same as that for conventional dry media sandblasting.
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.
Surfaces cleaned using wet materials achieve high levels of cleanliness. As such, the technique is suitable for use in preparing surfaces for coating and bonding operations. Very strong bonds are created when paint or other substances are applied on surfaces prepared using wet abrasive blasting.
