Applications of Sandblasting
Sandblasting is one of the many techniques that is used to clean surfaces through roughening. In this process, a skilled personnel operates sandblasting equipment to ‘blast’ compressed air or steam at high speed to clean various metallic floors or when etching glasses. For it to work well in cleaning surfaces, a sandblasting equipment should have an air compressor and a blaster nozzle all that will facilitate high pressure and speed of the fluid and hence proper abrasion.
Depending on the application, the grit of a sandblasting equipment varies. Some of the types of grits applied in sandblasting include Aluminium Oxide, Copper and Iron slag, Crushed Glass, Shell of Walnuts and Glass Beads. The main uses of Aluminium Oxide is for surface completion, and final preparation. When dealing with contaminants on surfaces that are aggressive, Glass grit is preferred. If the surfaces have paints and coatings that aren’t lined or smooth; plastic abrasives are used. when walnuts are used, they work perfectly on aggressive scraping while protecting underlying layers. Corn cobs is another grit that is used for the treatment of delicate surfaces. The substrate remains intact while the contaminants are stripped off. Though steel grit is softer than aluminum oxide; it works best on hard surfaces to smoothen them leaving a polished look.
Various industries experience rusty surfaces, machine wear and tear, burred components, surface scales and aging. This is when your company will need a sandblasting equipment to prolong the life of your machinery and tools. with the use of sandblasting, the method will eliminate all the rust and prepare the surfaces ready for application of coatings and paints. products that aren’t painted won’t appear appealing to customers. You will have to knock out surfaces imperfections to give smooth appearance before applying paints. Rust will lower the performance of every machinery and can even damage it permanently if it is not removed. Another use of sandblasting when removing moulds on plastic components. Cleansing of stones, concrete and brickworks requires sandblastic. The high velocity and pressure of grit propulsion gives an opportunity for cleaning of boat hulls.
Wear and tear, most metallic equipment go out of shape. To improve the shape, sandblasting equipment is applied to profile it. This has been commonly used in cemeteries to engrave the monuments. With the use of sandblasting equipment, three dimensional signings are achieved which meet the needs of most customers. There are many more functions of sandblasting on artwork. Buildings are refurbished through sandblasting equipment that modifies the appearance of wood to make it appealing. The uses of sandblasting equipments ranges from residential beauty, resurfacing applications, commercial cleaning to industrial shaping.
