（1）the characteristics of dry ice cleaning technology

Dry ice cleaning can also be called dry cold jet cleaning, carbon dioxide cleaning, or low temperature cleaning. The characteristics of dry ice cleaning technology determine it is different from other cleaning processes. The biggest benefit is that the dry ice cleaning solution for customers has the characteristics of applicability, environmental protection, practicability, economy and safety.

（2）dry ice cleaning technology applicable scope

Dry ice cleaning technology is under the condition of not changing the chemical characteristics of the removed matter, the rapid freezing of the removed matter, so that it forms micro-cracks, dry ice forced into the crack, rapid expansion, forcing the cleaning matter to peel off the attached body, so it belongs to the "physical cleaning method". So in theory, dry ice cleaning technology can replace the traditional physical cleaning process, such as sandblasting, water spray, wipe and other technologies.

（3）Application of dry ice cleaning technology

Dry ice cleaning technology can replace certain "mixed cleaning technology" (using pure physical cleaning process is not easy to clean, and forced to use a chemical change the way be cleared after feature, again through physics way to clean technology), such as the traditional oil cleaning oil, acid pickling metal surface rust stains, diluted with solvent paint, etc. Dry ice cleaning is widely used in military industry, nuclear energy, metallurgy, casting, petroleum, chemical industry, rubber, plastics, ships, automobiles, food, medicine, machinery, printing, electric power, electronics and other fields.

（4）the effect of dry ice cleaning

Dry ice cleaning has unique thermal effect and mechanical effect, so that it has superior cleaning effect, especially for precision mold on the fine texture and dense fine hole cleaning effect is better. It does not damage the mold and precision parts, does not change the tolerance, does not affect the surface finish of the object. However, the dry ice cleaning process also has a certain impact, and the relatively low cleaning temperature also has a certain applicability, in the cleaning should be reasonably used according to the specific situation.

Dry ice cleaning has the characteristics of safety, environmental protection and no pollution. Because only dirt is left after dry ice cleaning, dry ice particles have been vaporized into carbon dioxide gas, and no other chemical substances remain.
