Dry Ice Blasting: Latest Cleaning Technology There is now a more efficient and cost effective way of cleaning surfaces and that is through dry ice blasting or cold jet dry ice blasting which is quite similar to using sand, plastic beads and soda going through a pressurized air stream to impact a surface to be cleaned. The difference between dry ice pellets and the other media mentioned above (sand, plastic beads, and soda) is that dry ice pellets are softer and much less dense. Dry ice pellets turn to gas when it hits the surface being cleaned and so abrasion to the surface is minimal. When solid is instantaneously turned to gas, a process called sublimation, it absorbs a large amount of heat due to thermal shock thus doing a better performance in cleaning out molds by flaking it off more easily. Dry ice blasting generates no additional waste or secondary contamination unlike using other media or water blasting. Dry ice blasting, compared to traditional cleaning methods, is practical and affordable, and this technology is the best alternative when it comes to cleaning methods. Dry ice blasting can now be used in several applications including sensitive situations like removing flux from electronic circuit boards to heavy sanitation jobs like removing slags. You can also use it to blast food processing plastics and molded products. Since the dry ice pellets turn into carbon dioxide gas upon sublimation, the whole process is a dry one. Dry ice blasting can also be used in electrical applications since it is non-conductive unlike water which is a conductor, they are not advisable or permitted. Dry ice blasting can also cut cleaning time reducing cost compared to manual cleaning using solvents and wire brushes, and downtime is minimized in disassembling and reassembling machineries before cleaning them.

Another benefit is that there are no waste residue to dispose of since the dry ice pellets turns to gas and vanish in the air when the job is done. Environmentalists call this method a green method since the pellets turn into carbon dioxide gas which is food for plants and trees and is converted to oxygen and carbon. They don’t contribute to greenhouse gases and they don’t produce hazardous waste.
A Quick History of Experts
Businesses and industries should consider the advantage of dry ice blasting as businesses continue to migrate toward more environmentally conscious technologies. Dry ice blasting is a very safe and effective cleaning method for the food industry and for general cleaning since they can remove molds and bacteria easily so that the home and office spaces are left without these health hazards.
