Everyone knows that dry ice is the solid form of C. C is a colorless and odorless gas under normal conditions and naturally exists in the air. 1.
The advantages of dry ice as a spray medium: & . No secondary pollution: At low temperatures of ℃, C exists in solid form. Under normal pressure, solid C sublimates directly without a liquefaction process. This characteristic means that the spray medium disappears completely, leaving only the original dirt fragments to be processed. In addition, areas that cannot be cleaned with water can now be cleaned with dry ice. .Food grade, safe and reliable: The grade of C used in spraying is the same as that used in the food and beverage industry. It has been verified by the United States Department of Agriculture, Food and Drug Administration and Environmental Protection Agency to be safe and reliable. C is a non-toxic, easily liquefied gas. It is easy to store, does not conduct electricity, and does not support combustion. & .Waste utilization and energy saving: C is a by-product in industrial production processes, such as fermentation processes and petroleum refining processes, both of which produce high-purity C. The C generated during these production processes is collected and stored for use. When C sublimates and is emitted into the atmosphere during the injection process, no new C is produced.
