What are the types of abrasive blasting media? This article looks at the various blast materials available and how they can benefit your blast cleaning requirements.
How To Choose The Right Abrasive Media?
Both grit blasting and shot blasting techniques fall under the process commonly known as abrasive blasting.
Many people will use any or all of these terms to refer to these processes, despite the various distinctions. Simplified, grit blasting entails using angular particles as an abrasive blasting media, while shot blasting uses smooth or rounded particles.
Types Of Abrasive Blasting
Abrasive blasting is also known as sandblasting, grit blasting or media blasting. While people often get the various names mixed up, each type of blasting comes with its own mediums, uses, advantages and disadvantages.
However, in the end, the main use of abrasive techniques is to clean or prepare a surface to be modified or painted.
Depending on what you want to do with the material's surface, different abrasive techniques will be more suited than others. There are three common elements to any abrasive work.
The first is that there will usually be a blasting cabinet or area where the work will occur. They will all propel their abrasive blasting media at the chosen surface in one way or another. Finally, it is the most efficient and sustainable way to prepare industrial metal surfaces.
Here is a list of the different types of abrasive blasting, their blasting applications, and their positives and negatives.
Blasting for Surface Preparation and Finishing
When preparing or finishing a surface, choosing the right abrasive blast media is crucial; different abrasive mediums will give different finishes, meaning depending on what you want to create, you need to be careful in what you choose.
The different surfaces created by abrasives will also allow coatings to bond in different ways, meaning you should also consider which coating you want to apply when choosing a medium.
Factors When Selecting An Abrasive
When choosing your abrasive blasting media, it is best to consider the Mohs hardness scale, which measures the hardness of different materials. For example, talcum powder would score a 1, while diamonds would score a 10. Essentially, the higher the number, the harder the material. This also means that higher numbered materials can etch or abrase lower numbered ones.
Lower-numbered materials come with the added benefit of creating a finer finish, while higher-numbered materials are best at removing contaminants or rust. If you want to avoid leaving an anchor pattern or remove other substances such as grease or oil, softer materials are often best.
