What is the best sandblasting media for heavy rust?

When most of us think of sand blasting, the first thing that springs to mind is probably an operator using a bulky blasting machine to cleanup large sections of poured concrete; however, while the sandblasting process is disarmingly simple, it is also surprisingly all-round, and with the flame spray and knowledge sandblasting can be used on a wider selection of materials.

When used on ferrous metals such as steel and wrought iron, a sandblaster can be perfectly shown effective at removing deposits of rust and corrosion, revealing the undamaged metal beneath while causing At least structural damage to the metal itself. This process can be undertaken professionally by sandblasting services, or by the worker using a hired sandblasting machine.

HOW TO CHOOSE ABRASIVE BLASTING MEDIA:-

• Better “Soft” Than Sorry:-If you’re not sure whether the surface you are blasting can handle a more abrasive material, then you will probably be better off starting with a gentler medium. Walnut shells or corn cobs can be an excellent choice for softer surfaces such as wood — they won’t cause etching. They also provide the additional benefit of being biodegradable, making them among the most environmentally-friendly blasting media.

• Make It Shine With Glass Beads:-If you’re looking to achieve a smooth, bright finish, glass beads can be your best option. Glass beads are typically made from fine soda-lime glass that places minimal stress on the surface material. Glass beads are also recyclable and can be used up to 100 times before replacement, making them an extremely cost-effective option.

• Remove Paint With Aluminum Oxide:-Aluminum oxide is harder and sharper than glass beads. It’s ideal for use in paint removal and general cleaning applications — it’s also frequently used for glass etching.

• Choose Plastic for Automotive and Aerospace Applications:-Plastic is extremely soft, making it an ideal medium for removing paint from the surface of fiberglass parts. Fiberglass parts are commonly used in the manufacturing of automotive, aerospace, and marine products, without etching or stripping. 

• Use Silicon Carbide for Fast Etching:-Silicon carbide provides an extremely abrasive cutting action that is ideal for fast etching of glass, stone, or other hard surfaces. It also works well for removing rust or paint.

• Find Super-Hard and Aggressive Steel Media:-Media made from carbon steel is available in both form shot or grit form. Steel shot has a round shape and can be used for polishing and peening applications. Steel grit has offers a more angular shape and sharper texture. that is used to remove rust, paint or scale from steel surfaces.

• Avoid Sand:-However, many companies are moving away from the sand as a blasting medium for a number of reasons. Sand contains silica, which is known to cause serious respiratory illnesses for workers involved in the sandblasting process. Additionally, sand contains a high moisture content that can lead to the premature demise of blasting equipment.
