Dry ice cleaning technology usually uses dry ice machines (dry ice machines, ice machines, dry ice granulators, dry ice granulators, and dry ice granulators), as well as dry ice particles of certain specifications, and then uses dry ice cleaning machines (dry ice jet, dry ice jet cleaner, dry ice cleaning mold, dry ice mold cleaner) to compress air and dry ice particles with certain pressure. After mixing, spray it onto the cleaned material surface, and the impulse generated by the low temperature and high speed movement of dry ice particles will cause the dirt to crack.

Therefore, it belongs to "physical cleaning method". Therefore, theoretically, dry ice cleaning technology can replace the traditional physical cleaning technology, such as sand blasting, water spraying, wiping and other technology-technology.

From the perspective of industrial practicability, the application of dry ice cleaning technology is related to national environmental awareness and legal requirements. Now people's awareness of environmental protection is becoming stronger and stronger, and the country has also issued relevant policies to enhance environmental awareness and improve environmental protection requirements, while the traditional process can no longer meet the environmental protection conditions, so dry ice cleaning technology came into being to replace the traditional cleaning process. From the perspective of technology, the principle of any cleaning process is to ensure that the cleaned workpiece is not damaged and the integrity of the workpiece is guaranteed. The dry ice cleaning process must also follow this principle. Dry ice cleaning sprays dry ice particles onto the surface of the workpiece. The workpiece surface must withstand certain wind pressure. If the workpiece surface cannot withstand certain wind pressure, dry ice cleaning process cannot be used.

Dry ice cleaning is widely used in military industry, nuclear energy, metallurgy, casting, petroleum, chemical industry, rubber, plastics, ships, automobiles, food, machinery, printing, power, electronics and other fields. Even the car washing in our daily life is also integrated with dry ice technology to achieve water-free dry ice car washing, which is both efficient and environmentally friendly.
