What is the principle of non-conductive cleaning motor for dry ice cleaning machine?

The dry ice cleaning machine of Wantong does not conduct electricity when cleaning the motor, mainly based on the following principles:
The chemical properties of dry ice itself: Dry ice is solid carbon dioxide, which belongs to covalent compounds. The carbon atoms and oxygen atoms in its molecules are covalently bonded, without freely moving electrons or ions. At room temperature and pressure, dry ice will directly sublime from solid state to gaseous carbon dioxide, without producing conductive ions or electrons during the entire process, which fundamentally ensures that dry ice will not conduct electricity during the cleaning process.
The physical characteristics of the cleaning process: The dry ice cleaning machine uses high-pressure air to spray dry ice particles onto the surface of the motor for cleaning. During this process, dry ice particles collide with dirt and other substances on the surface of the motor, utilizing the low temperature of dry ice to freeze and brittle the dirt. At the same time, the dry ice particles instantly sublime, transforming from a solid to a gas, expanding their volume hundreds of times, generating a strong impact force that peels the dirt off the surface of the motor. The entire cleaning process did not use conductive liquids or other conductive media, only the physical action of dry ice particles, so no conductive path will be formed.
No residual conductive medium: Dry ice completely sublimates into gaseous carbon dioxide during the cleaning process, and does not leave any potentially conductive liquid residue on the surface of the motor like water or other chemical cleaning solutions. After cleaning, the surface of the motor is dry and there are no substances that can cause conductive phenomena, ensuring the electrical safety of the motor during and after cleaning.http://www.gbqxsb.com
