After cleaning contaminants on a surface, the results vary greatly depending on your application method. Although several blasting methods, including dry ice blasting, most people rely on the old sandblasting process to remove pollutants from surfaces.
This article helps you choose between dry ice blasting and sandblasting by detailing the two methods, their application, advantages, and drawbacks.
What Is Dry Ice Blasting & How Does It Work?
Dry ice blasting is a technique that uses solid carbon dioxide pellets to clean contaminated surfaces. The method is neither abrasive nor too aggressive. Instead, the technique uses ultra-cold temperatures, impact, and sublimation expansion to weaken and remove rusts, paints, and undesired impurities without modifying the cleaned surface.
Unlike other blasting techniques which use abrasives, dry ice employs solid carbon dioxide pellets that sublime when impacted – or instantly change into gas – upon striking. Dry ice blasting also has the advantage of leaving no secondary residue, such as liquid or minute particles.
Sandblasting & How It Works
Sandblasting removes impurities from a surface by “shooting” sand particles at an extremely high speed. Even though sand is the common abrasive, the perfect name for this technique is abrasive blasting since other particles can be used.
The method is effective when a hardened contaminant, such as paint, is removed off a surface. Sandblasting, like sandpaper, uses friction to disrupt and remove surface impurities and allows the user to access hard-to-reach areas. As mentioned earlier, dry ice blasting, also referred to as dry ice cleaning, works similarly. Dry ice pellets are blasted at a high velocity at the surface. The main difference lies in the medium used to blast off the dirt. Abrasive blasting relies on friction from sand, glass, or other abrasive but dry ice blasting depends on extreme cold to remove pollutants.
When choosing a blasting technique, sandblasting might be an excellent solution if your situation necessitates extensive blasting and you don’t bother with the extra cleanup. Similarly, dry ice blasting may be a good option if you want precision, simplicity, speed, and the certainty that you won’t vandalize the material you blast.
