Sand blasting is one of the most effective ways of surface treatment. It is used to rough up, give haze, clean, and remove plaque and other debris from a variety of surfaces. A variety of surfaces can be blasted including ferrous metals and their alloys, stainless steel, nonferrous metals and their alloys, plastics, concrete, wood, stone, glass, ceramics and other materials. The most important thing is to choose the right equipment and abrasives.
Wet blasting is blasting using water and sand. When wet blasting is chosen, dust content in the air is several times lower than blasting in a usual way.
One of the biggest drawbacks of metal is corrosion. Intensity of corrosion depends on the location, environmental conditions and harmful substances. Therefore, the metal corrosion resistance can be very diverse. In order to remove the resulting corrosion requires a lot of time and money, but there is one solution for those who want to save. This is blast cleaning - blasting. It is blasting which reduces the time and cost of cleaning. Blast cleaning allows to fully getting the job done by easily accessing any place of the construction which is needed to be cleaned. When blast cleaning is used, the surface is roughed up at the same time so there is better paint adhesion with the surface. Blasting with compressed air is performed by supplying abrasive (sand) to the flow of air and directing air and abrasive mixture at high speed from the nozzle into a cleaning surface.
Blasting is also useful in the timber industry. Blast cleaning easily removes paint or soil layers, as well as wood aging is possible, which will give a new look for wood and its products.
Blasting method can also be used for cleaning graffiti, monuments, walls, inside and outside of buildings and other surfaces, which flexibility is being provided by blasting.
