Are you tired and fed up with dealing with dirty and corroded surfaces? You have to look no further because blast cleaning technology is here to save the day! This powerful cleaning method uses compressed air or mechanical energy to forcefully remove dirt, paint, rust, and other unwanted materials from various surfaces. One can blast away those pesky stains and bring back that shine!
Types of Blast Cleaning Methods
Sandblasting method is one of the most traditional forms of blast cleaning methods. It cleans the surfaces by using compressed air to propel various abrasive materials at high velocities. Sandblasting is widely used in industrial and construction applications. One can use it for artistic and decorative purposes.
The shot blasting method uses steel or glass beads as the abrasive material. When propelled at high velocities, the beads clean the surface. One can use this blasting method in metal fabrication and surface preparation for painting or coating.
Different media like aluminum oxide, plastic, GMA Garnet, and organic media like walnut shells are used for different requirements. Each media is unique, while some are used for their recyclability and others for their low pressure.
Applications of Blast Cleaning
Surface Preparation: Before painting or coating, anyone uses blast cleaning as a surface preparation technique. The high-velocity impact of the abrasive particles removes surface contaminants, corrosion, and other unwanted materials, leaving a clean and smooth surface ready for painting or coating.
Metal Fabrication: Blast cleaning is commonly used in metal fabrication to remove surface contaminants and rust from metal surfaces. This method improves the adhesion of coatings and allows for better welding and bonding.
Marine Industry: Blast cleaning is widely used in the marine industry to remove marine growth and corrosion from ship hulls. This method improves the ship’s performance and extends its vessel lifespan.
Construction: You can also use blast cleaning technology to remove paint and other materials from concrete and other surfaces. This method can prepare surfaces for new construction or restore old ones.
Standards for Preparing Metal Surfaces for Abrasive Blasting
Several standards govern the use of abrasive blast cleaning, established by organizations such as SSPC, NACE, and ISO. These standards specify different levels of cleanliness required for the surface, with
“White Metal Blast Cleaning” is the highest level of cleanliness, requiring the surface to be free of all visible contaminants.
“Near-White Metal Blast Cleaning” and “Industrial Blast Cleaning” also have specific requirements for surface cleanliness.
“Commercial Blast Cleaning” has the lowest level of requirements.
Each standard also specifies the percentage of the surface area that must be free of contaminants. It is essential to consult with a professional and follow the appropriate measure to ensure the surface is suitable for further coating or treatment.
Different equipment:
Blast pots are compact and efficient equipment. You can use it with various abrasive media on-site at a blasting facility.
Blast rooms, on the other hand, offer a controlled environment for industrial shot blasting.
One can use automated blasting machines to achieve consistent results and productivity. These machines are typically powered by a powerful air compressor that provides sufficient velocity at the nozzle.
It is crucial to remember that safety gear is advised, such as respiratory masks and blast suits. Doing this ensures that you may protect workers from hazardous flying particles during operation.
Take Away:
Blast cleaning technology is the ultimate solution for tackling dirty and corroded surfaces. The powerful cleaning methods will blast away dirt and grime in no time, leaving behind a clean and smooth surface. And with a wide range of applications in industries, there’s no limit to how to use this technology.
