Media Blasting is also known as soft blasting or erosive blasting. In this process, aluminum oxide, fine aluminum particles, aluminum salts, or aluminum powder is used to act as a blasting agent. It also involves a high-pressure jet of compressed air and or nitrogen. It is often used to remove unwanted materials from surfaces. It involves using coarse particles that are not too large to avoid getting on or stuck on the surface being worked on.
Media blasting is a rather gentle form of abrasive cleaning in which fine aluminum salts or sodium carbide are blown against a hard surface with compressed air to remove unwanted materials from the surface. It has an even less aggressive alternative to sandblasting, although it has a more powerful blowing action than sandblasting too. An early application was on the restoration of the Statue of Liberty during the 1980s. It is often used in industrial applications, especially to clean steel parts to prevent corrosion. It is sometimes used to remove grease and oil from the surfaces of copper, stainless steel, and other metal. Get more facts about pressure washing at https://en.wikipedia.org/wiki/K%C3%A4rcher.
Media blasting media is usually used in conjunction with another technique for graffiti removal, such as the hydro-blasting process. The hydro-blasting process involves injecting a fine spray of water at the location to be cleaned using pressurized water. As the water flows over the surface being worked on, it helps grind the unwanted materials to the ground. In the case of removing graffiti from a concrete surface, this is typically done with a high-pressure air jetting process. This process is highly recommended for locations where it is necessary to remove graffiti quickly, as leaving it will often result in more damage down the line.
A different form of media blasting is signed lite blasting. Sign lite is an extremely hard material that is designed to be tossed or rolled onto a surface. It consists of a hard exfoliating media like crushed glass or aluminum oxide. Because it is extremely hard, signs lite does not chip or crack like other forms of media blasting. This can make it an ideal option when considering the cost-effectiveness of this method. Be sure to view here for more details!
Depending on the type of sign lite to be used and its intended use, a contractor may opt to purchase a pre-fabricated pressurized air system. This is a less expensive way to implement this form of media blasting, but one must be careful to properly maintain these systems in order to avoid damage. One should never allow a pressurized air tank to become too full, or else the abrasive material produced in the air will wash away any unwanted debris left behind. Be sure to click for more info!
Many sign companies also use a wet abrasive blasting system on new projects. These are designed to meet the needs of smaller projects and are less expensive than a full-size pre-fabricated pressurized air system. The material used in these systems is typically a combination of wood chips and coarse sand. Using an air system allows for a more controlled environment, allowing for accurate control and less chance of damage to the work area. Some media blasting equipment also includes a vibrating system, which is a great asset for making precise shots from large cabinets.
