It originated at Lockheed in the 70’s when a coatings engineer, Calvin Fong, was researching ways to rejuvenate aircraft primer. The technology was introduced commercially in 1987.
It is a process in which particles of solid carbon dioxide (dry ice) are propelled with high velocity air (usually 80-100 psi) to impact and clean a surface.
It is made from liquid carbon dioxide. CO2 exists as a liquid only under high pressure. When it drops to ambient pressure (the normal pressure that surrounds us), approximately half turns to gas and half turns to solid. The solid, usually in the form of fluffy snow, is then compressed to form dry ice blocks, pellets or nuggets.
It is frozen carbon dioxide (CO2). Carbon Dioxide is a gas which is natural to our atmosphere. It is inert. It is non-conducive. Nearly all dry ice that is used in dry ice blasting is recycled from factories and industrial processing.
Dry ice blasting is a relatively new cleaning process using solid CO2 pellets (known as dry ice). It is primarily used for industrial use in a variety of applications of which black mold removal is an exceptionally good one. The pellets sublimate (convert directly from a solid blast pellet to a vapor (CO2) leaving no residue. The dry ice blasting process is superior to blasting with sand or glass bead and other
types of cleaning methods for numerous reasons (see Dry Ice Blasting Comparison Chart). Today, the dry ice cleaning method is quickly becoming favored for environmental as well as production reasons. Because of tremendous environmental regulations, the industry has accelerated to minimize waste. Also, there is a growing consciousness that many are placing now on the global environmental impact of their production practices. However, these benefits are accentuated due to the tremendous
performance gains through dry ice blasting — little or no production downtime, quality of clean and minimized damaged to equipment.
