About Dry Ice Blasting

Dry ice blasting is a process whereby kinetic and thermal energy is transferred when the accelerated dry ice pellets strike the surface being cleaned. Dry ice and air combine to remove the unwanted material and leave a clean surface free of any contaminant.

1. Kinetic Effect 2. Thermal Effect 3. Sublimation 4. After Blasting
Dry ice pellets are accelerated by compressed air to high speeds – fracturing the top layer of dirt/residue. Once the dry ice penetrates the dirt/residue, the temperature of both the dirt/residue layer and the substrate decreases. The different materials contract unequally and the adherence between them decreases. This thermal difference helps to separate the dirt/residue from the substrate. After the dry ice makes its initial impact, it instantaneously turns from a solid to a gas. The volume expansion (by a factor of 700) causes a micro explosion that detaches the dirt/residue from the substrate. The substrate is clean, dry and completely intact.

Recent advances in technology have made dry ice blasting an increasingly practical and affordable alternative to traditional cleaning methods such as sand, soda, or water blasting and manual cleaning with solvents.

Dry ice blasting can be used in a wide variety of applications ranging from sensitive cleaning situations, like removing flux from electronic circuit boards, to heavy sanitation jobs, like removing slag from automotive assembly rails.

Dry ice blasting has a wide range of applications in food processing, plastics and molded products industries, automotive, printing, aerospace, contract cleaning, general maintenance, and many other industries. Listed below are the primary benefits of cleaning with dry ice:

Since dry ice sublimates (turns into carbon dioxide gas) upon contact, the process is dry. Dry ice blasting is non-conductive and safe for electrical applications where using water may not be advisable or permitted.

Frequently the "clean-up" from your current cleaning method is worse than the cleaning itself. Dry ice solves that problem by eliminating secondary waste. Dry ice pellets do the job and simply disappear, eliminating the high disposal costs associated with other materials.

The non-abrasive nature of dry ice means that cleaning won't damage sensitive parts or production equipment, extending the useful life of equipment and minimizing the chances of defective products.

Dry ice cleaning is a "green" process that uses small pellets of recycled carbon dioxide to clean a surface. The pellets sublimate (turning from solid directly to gas) during the cleaning process. The carbon dioxide gas is absorbed by trees and plants and converted into carbon (plant growth) and oxygen. Dry ice blasting is really "green" recycling at its best.

Dry ice blasting does not contribute to greenhouse gasses and no hazardous wastes are produced. With basic safety precautions, the work process is safe. No ozone-depleting chemicals are used and there is no exposure to Volatile Organic Compounds (VOC).

Utilizing dry ice blasting can help companies achieve Sustainability Objectives.
