Dry ice blasting is an excellent choice for cleaning all kinds of surfaces. Its versatility makes it useful for accomplishing tasks ranging from deck refurbishing to assembly line maintenance. However, many people may be uncertain as to what exactly is being shot out of a dry ice machine. Let’s take a look at what dry ice really is.
Dry ice is, simply put, solid carbon dioxide, a compound that is most often referred to in its gaseous form. Carbon dioxide, or CO2, is a natural part of the earth’s atmosphere, and we release it from our bodies every time we exhale. Plants rely on this gas for the process of photosynthesis, during which they produce their own food (glucose). Carbon dioxide is an important part of the earth’s natural greenhouse effect, trapping the heat from the sun’s rays and keeping our planet warm and hospitable. Carbon dioxide gets a bad reputation due to there currently being an excess amount of it in the atmosphere. Human impact in recent decades has caused the levels of CO2 in the air to increase above normal thresholds, thus contributing to climate change.
The first step in the creation of dry ice is to produce gases that contain a high concentration of CO2. These gases are usually unwanted byproducts of other industrial reactions, so we collect and recycle all of our CO2 rather than creating our own gas. The collected gas is then put into a high pressure state and refrigerated, causing it to condense into a liquid. At this point, all that’s left to do is to reduce the pressure even further, causing the temperature to drop, and turning the liquid carbon dioxide into dry ice snow. This snowy substance is gathered and compressed into small pellets. The dry ice is now ready for use!
Because the carbon dioxide needed for dry ice creation is taken from recycled sources, using dry ice helps reduce the amount of CO2 gas that is being let into the atmosphere. The creation process itself is relatively simple, and easily mass-produced. Dry ice itself is non-toxic (as its just solid carbon dioxide!) and will instantly dissipate upon use, leaving no secondary waste to clean. It’s extreme coldness makes it excellent for clearing unwanted living things from wall lining, such as mould.
