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 typical use, a sandblasting tool must have the major parts, a blaster nozzle and an air compressor that work to give the fluid a high pressure for abrasion.
There are various types of grits with regard to the uses. Some of the types of grits applied in sandblasting include Aluminium Oxide, Copper and Iron slag, Crushed Glass, Shell of Walnuts and Glass Beads. Aluminium Oxide is mostly utilized when preparing surfaces and during finishing. Glass grit is ideal for contaminants removal on aggressive surfaces. Plastic grits are used mainly to rub off paints and rough coatings without damaging the lower surfaces. Walnuts, on the other hand, work best in aggressive scraping and cleaning. Corn cobs is another grit that is used for the treatment of delicate surfaces. All these protect the main substrate while removing the contaminants. Though steel grit is softer than aluminum oxide; it works best on hard surfaces to smoothen them leaving a polished look.
There are several inevitable challenges that industries experience on various surfaces and they include machine wear and tear, surface scales and aging, burred components and rusty surfaces. For such problems, sandblasting equipment is the solution to extend the machinery and equipment life. Sandblasting is a technique that allows for easy removal of rust and making surfaces ready for coatings and paints application. Every customer will buy a beautiful and good looking product especially those that are painted. paints can only work if the surfaces are smooth and without any contaminant. rust should be removed immediately to avoid affecting the performance of the machinery or permanent damage. Sandblasting is also used on plastic components that have moulds. There is a wide list of sandblasting equipment and cleansing of stones, bricks and concrete work is another. The many applications has not left out the cleaning of boat hulls which utilizes the high propulsion of grits.
Wear and tear, most metallic equipment go out of shape. To improve the shape, sandblasting equipment is applied to profile it. An area that has exploited more this application is engraving of cemeteries. With the use of sandblasting equipment, three dimensional signings are achieved which meet the needs of most customers. artwork is another area that has found most uses of sandblasting equipment. 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.
