Looking to use dry ice blasting to assist in cleaning your industrial equipment or in your fight against household mould? Scrub Zero has you covered with some fun facts about dry ice blasting to help you decide if it’s right for your needs.
Though it was first discovered back in 1835, solid carbon dioxide wouldn’t be named “dry ice” for almost hundred years, in 1925 by an American company. Since then, it has been sold commercially and is used as both a cleaning tool and as a coolant.
Dry ice is formed when carbon dioxide is industrially cooled to -79 degrees Celsius. It is odourless, non-toxic, and safe to use on a variety of different surfaces. Carbon dioxide is a natural component of the atmosphere, so dry ice doesn’t introduce any new hazardous chemicals into the environment. At standard pressures and temperatures below -56 degrees Celsius, dry ice will change into a gas without first going through a liquid phase, a phenomenon known as sublimation.
Dry ice is made by pressurizing high amounts of carbon dioxide gas. The gas is usually taken from recycled sources, where it is an unwanted byproduct of other reactions and industrial processes. It is first purified to ensure that only carbon dioxide remains, and then held at cold temperatures until the carbon dioxide becomes a liquid. Then, the pressure is lowered. This causes some of the liquid to vapourize and drops temperatures even lower. The leftover liquid then turns into a snow-like substance, which is finally pressed into the pellets that we know as dry ice.
Aside from cleaning, dry ice is most often used as a coolant. When mechanical cooling systems aren’t available, dry ice is a common alternate substance that is used to great effect. You’ve likely been a Halloween themed party or concert featuring fog machines; sublimating dry ice is likely what you’re watching. Dry ice can even found on Mars’ polar ice caps!
