Industrial sandblasting is basically the business of removing scale, paint and rust from various metal components for the customers. The companies providing this service are also known as stripping companies and they make use of sandblasters for stripping objects completely. These objects can be as large as the full-size trailers and automobiles or as small as the antique and exclusive toy cars. Typical sandblasting services provide a wide assortment of blasting media starting from walnut shells and baking soda to sand. Here, it is to be noted that each specific media type has its very own specialized use.
Why go for Professional Sandblasting?
There are some important steps taken for removing old paint, rust, old chrome and rust plating for refurbishing, refinishing and restoring metal or steel items. The most basic technique used for preparing a surface for a completely new finish is manual sanding which can always be very difficult and even time-consuming. Another method used for this purpose is chemical stripping which can again be very dangerous and messy for the environment and for the user. This is the main reason why professional sandblasting is considered one of the most effective methods of removing the unwanted remains on metal surfaces. This is one procedure which can also be used for removing rusted steel from the component that is being stripped.
Industrial Sandblasting- The Complete Overview
Industrial sandblasting is a procedure where the objects that need to be sandblasted are brought to the location of the stripper. Then the items are positioned within a blasting booth with appropriate media loaded in the blasting machinery. The operator starts at one end of the object that is being blasted and then works the small areas till the raw metal finish is remaining. The surface that is sandblasted needs to be covered using a sealer or primer post sandblasting. This helps in resisting rust from moisture present in air. There are even mobile sandblasting companies which are used for stripping cement and brick buildings before the initiation of the restoration or painting procedure. The structures which are generally sandblasted without being transferred to the location of the sandblaster are overpasses and bridges found on the large highways. Mobile sandblasting service providers generally load all their devices on a trailer or truck and get to the site of the overpass or the bridge that needs to be sandblasted. These services set up huge tarpaulins for protecting the passing traffic from any kind of damage. They blast the entire area for removing rust, paint and various other substances allowing the workers to completely refinish the entire thing. During the sandblasting procedure, the areas that require proper protection from high-pressure sand like windows and doors are completely covered using rubber pads or mats. Ornamental trim, wooden doors and woodwork are objects which are not sandblasted. Therefore, they remain protected against all kinds of damages arising out of professional sandblasting.
Industrial sandblasting is one of the most used and the oldest procedures of treating metals. There are innumerable abrasive materials loaded using a vacuum system which pulls the grit from the storage tank. This is something which is also done manually. There is a control valve which operates in combination with compressed air which is forced into the storage tank which automatically pressurizes the receiver. It is when the compressed and high pressure sand goes out of discharge line that it pulls grit for effectively impinging the targeted metal object. This procedure is not very well monitored or controlled particularly when it does not seem to be an integral part of the manufacturing procedure. It is basically defined in the form of a multipurpose method which is used for roughening or cleaning surfaces. Proper and effective sandblasting tools are required for carrying out this procedure. Typical applications require sandblasting tools like air compressor and blaster nozzle for propelling the abrasive at a very high pressure. The grit type generally varies depending on specific application.
Common varieties of grits which are used for industrial sandblasting include Iron and Copper Slag, Crushed Glass, Walnut Shells, Aluminum Oxide and Glass Beads. Aluminum oxide is generally used for surface preparation and finishing. The perfect grit that can be used for the removal of contaminants from the surfaces that tend to be a little aggressive is glass grit. Plastic abrasives are used for scraping off old paint and coatings without causing any damage to the underlying surface.
