• Media Blasting and Chemical Stripping - How They Restore Surfaces

    Media Blasting is one of two methods that create a physical barrier to moving media. The other method, known as scumbling, uses high pressure and very high temperatures to physically remove materials. Both media blasting and crumbling have applications in many industries including building construction, demolition, and moving and warehousing to name a few. They both can be applied to delicate surfaces, such as glass and ceramic, or very tough metals like iron or steel. In this article, we'll take a quick look at how media blasting and crumbling work and why you might need to use them. Click to read more here.

    Media blasting is simply a low level form of rough abrasive blasting where sodium bicarbonate pellets are blasted onto a smooth surface with compressed air. It has a somewhat less harsh, less abrasive effect than scumbling. Before media blasting, the existing finish has an opportunity to take on a patina which can make the finish look old, dull, or dingy. An early application was in the maintenance of the Statue of Liberty during the late 1800's. Visit this link to learn more.

    One of the advantages of media blasting is that the soft surface of the aluminum allows it to be used for many applications beyond paint removal. Aluminum oxide is often used to reduce rust build up on metal objects. In addition, aluminum oxide may be applied to prevent the growth of new metallic flakes on an old surface. By removing the metal oxide coat, this method can help reduce the need for future paint or stripping.

    Scumbling is another way of removing older, dull, or damaged finishes such as aluminum. A scumbling procedure involves the use of fine grit aluminum oxide sandpaper or cotton balls. Various sized balls are placed on the surface to be scrubbed. A squeegee-type device is then used to apply a mixture of coarse sandpaper and cotton balls to the scrubbed areas. The scrubbing action helps to remove old deposits from the surface of the materials and to promote the growth of new and evenly grained surfaces.

    In cases where the existing finish has begun to flake or chip, the manufacturer may opt to use an air compressor to perform the final media blasting or chemical stripping. The compressor shoots compressed air into the area to be treated. The resulting high pressure created by the air compression helps to remove any large crystals or chips that remain after other finishing methods. The final product after this process is a clean, smooth surface free of imperfections.

    Media blasting and chemical stripping are two ways to restore an uneven, dull, or damaged surface. By either method, you will quickly see that your investment in time and money will pay off by having a workable, durable finish that will stand the test of time. You may also find that this finishing method offers a cost-effective way to improve the appearance of your existing floor or wall. No matter what the reason for performing these finishing techniques, using these tools to restore a badly stained or chipped surface will prove to be a wise investment.

  • Media Blasting As an Equipment to Perform an Assistant Maintenance and Repair Process

    Media blasting is an extremely gentle form of rough abrasive blasting where sodium bicarbonate pellets are blasted vigorously against a hard surface with compressed air. It has a much gentler abrasive action than regular sandblasting. An early application was on the restoration of the Statue of Liberty in the late 1980s. It is also used on steel and aluminum to remove rust and corrosion and to increase the luster of painted finishes. In the past, its application was limited to the interior surfaces of automobiles, primarily to remove dust and to prepare the surface for painting. Click for more details.

    A different kind of this media blasting device is called a blast gun. This is a cylindrical gun with a blast nozzle at the end. Its job is to shoot very high amounts of media at a single pressure so that the surface being worked on becomes smooth and clean. A blast gun consists of a cylinder, a nozzle, a hopper and a tank. The pressurized air is shot through the hopper and into the cylinder.

    To perform its job properly, it should be operated at the proper pressure. For this, check the gauge. Too little pressure can strip away the protective coating while too much can result in a blast effect that causes corrosion. In addition, the air flow and the length of the media blasting cycle should be selected appropriately. For example, the maximum air speed achievable should be selected when working on corroded metal. Also, it should be noted that the higher the pressure achieved in media blasting, the lower the cost is for the coating and the longer it takes to bring the surface to a level of protection sufficient for a clear proof coating.

    To carry out the job properly, it is important to understand the process completely. This will allow the worker to select the appropriate equipment, wear the proper protective clothing, assemble the parts correctly and ensure that all other factors are met. There are some special cases where special tools or techniques must be employed. For example, to ensure the proper formation of a good and effective layer of corrosion-proof coating on an engine bay, the worker must mount the drum in a positive camber and mount the flywheel at the correct rotation for best results.

    There are various benefits associated with using media blasting equipment. One of its advantages is that it produces rapid effects and high speeds. It also ensures a clean finish and minimizes debris and powder coating. Abrasive media blasting equipment is used for medium-sized to larger applications. One such application is found in the aerospace and defense industry, where it is often used for final inspection of complex airframe components and parts before assembly.

    In addition, media blasting equipment has applications beyond the automotive sector. It is used to clean up residential properties such as office buildings and apartment complexes after flooding, to remove asbestos from home-related materials and to reduce the threat of silicosis in personnel who work with asbestos. It is also used to blast away unwanted debris such as tree leaves and branches, clearing the way for new foliage to grow. Other projects may include removing road kill and removing rubbish from sidewalks and parking lots.

  • Different Uses of Media Blasting in Aggressive Security Methods

    Media blasting is an aggressive form of rough abrasive blasting where sodium bicarbonate pellets are blown against a hard surface with compressed air. It has less of a forceful effect than fine sandblasting. An early application was on the preservation of the Statue of Liberty in the late 1980s. It was used to help preserve the statue while it was being restored after hurricane Andrew destroyed part of New York City. Media blasting is also used to remove graffiti from public areas, and it can be used to clean up oil spills and remove dirt from the soles of tires. Click here to hire media blasting experts.

    Today, media blasting finds wide applications in a variety of restoration projects, both commercial and residential. For instance, it is used to restore plaster and underlying masonry in flood damage restoration projects. The procedure removes the grit and pebbles from the plaster and wood chips that may have been left in place during the flood. Another application is in the preparation of concrete slabs for poured buildings. During these applications, high pressure air is blown over the concrete to remove gypsum, which is primarily found in older masonry.

    When it comes to materials, media blasting finds its use in a wide range of applications. One material that is particularly interesting is sign lite. Sign lite, which is also known as sign board, comprises crushed glass pieces. Sign lite is typically very smooth so that it may be applied to pre-existing surfaces without inflicting scratches. It is primarily used on outdoor signage, signs and window decorations and to protect the metal components of signs. To check out the best media blasting services, click here.

    Another product that finds application in media blasting is aluminum oxide sand. Aluminum oxide is commonly added to concrete as a finishing agent. This oxide is said to have very good anti-corrosion properties. The main reason why this product is used is because it is easily abrasive resistant and can be easily shaped by hand or by using a roller. This product does not require any kind of maintenance, so it is one of the best choices to use in protecting the surface of concrete from various damage that could be caused by various external factors like moisture seepage or acid rain.

    Other uses of pressurized air and abrasive material are that it creates surfaces for signs and can also be used in graffiti removal. Graffiti removal with media blasting involves blasting a fine abrasive material against a graffiti wall and leaving a scar. In the process, graffiti is also removed. Media blasting may not be the most appropriate solution when it comes to graffiti removal because it may not leave a graffiti wall with a clean outline.

    With all these applications, it is not surprising that media blasting has become one of the most popular options for sandblasting. As technology advances, it is expected that other new applications for the media blasting equipment will also come out. There are different brands of media blasters in the market today. A good example of a reliable brand is the Sandblast cabinet.
