What Can Sandblasting Be Used For?

W

Sandblasting is a generic method used for roughening the surfaces and cleaning them. The process is carried out through sandblasting equipment and involves ‘blasting’ compressed air or steam at high speeds for glass etching or cleaning metallic surfaces. For typical applications, equipment for sandblasting consists of a Blaster nozzle and air compressor for the propulsion of abrasive material under high pressure. Depending on the application, the type of grit varies.

The use of grit

Some common types of grits used for sandblasting include: copper and iron slag, aluminium oxide, crushed glass, glass beads and shells of walnuts. Aluminium oxide is usually used for surface finishing and preparation. Glass grit is ideal for removing contaminants from surfaces that are aggressive in nature. Plastic abrasives are used to scrape off paint and other coatings without damaging the underlying surface. Similarly, walnut shells come in handy for aggressive scraping and cleaning without causing harm to the surface. Another grit commonly used for treatment of delicate surfaces is corn cobs. The substrate remains intact and contaminants removed. Steel grit is used to treat rough and aggressive surfaces. It is softer than aluminium oxide. On the other hand, steel shot as grit gives the metallic surface a smooth and polished look.

Cleaning and sanding surfaces

Rusty surfaces, burred components, surface Scales and aging, machine wear and tear are some inevitable problems that will arise for the Australian industry. This is where sandblasting equipment plays an important role in extending the life of machinery and equipment. Sandblasting allows easy removal of rust and preparation of surfaces to apply coatings and paints. Without paint, lustre and perfect finishing, products do not appeal to the customer in a highly competitive market. Before applying the paint layer, sandblasting effectively knocks out surface imperfections thus gives a smooth surface. Rusty components affect the performance of machinery and if rust is not removed in a timely manner, machine or part can be damaged. Additionally, sandblasting is used on plastic components that have been developed form. Sandblasting equipment also used for cleansing of stones, bricks and concrete work. In addition, the high velocity of grit enables efficient cleaning of boat hulls too.

Surface treatment and thread

Due to wear and tear, metallic components can go out of shape. With the help of sandblast equipment, edge profiling and component improvements can be achieved. A typical application of sandblasting equipment is monument letter engraving for cemeteries. Three dimensional signing achieved through sandblasting brings more satisfaction from customers compared to flat signs. In addition, for interior decoration, sandblasting is used for artwork; the technique works superbly on acrylic. Buildings are refurbished through sandblasting equipment. For wooden signage, the rings on the wood are made significant from the grains by raising them through sandblasting which gives a very nice appearance. Words and images may be carved through glass. This effect is also referred to as the ‘snowing’ of glass which makes it translucent. The sandblasting stencil used for glass carving allows different angles for creating different shades. With the perfect lighting, it will give your interior a great appearance. Though, the sandblasting equipment for artistic effects is fairly expensive, the beauty of glass carving and etching is worth it.

Sandblasting equipment can be used for several purposes, including residential beauty, cleaning commercial and industrial machining or grinding applications.
