How does dry ice achieve non-destructive cleaning? Dry ice cleaning is based on the physical principle of impact, thermal expansion and contraction, sublimation, and then turns into cold air flow. Although this cleaning method uses a series of cleaning processes such as physical impact, thermal expansion and contraction, instant sublimation and explosion.
There will be a great impact force on the surface of the object being cleaned, but in fact, Orrich chooses 3MM dry ice, which is a 3MM small particle under normal conditions. In the cleaning process, the impact force is not used to impact the surface of the object being cleaned, because the volume and weight of dry ice are very small, and it will sublimate during the "impact" process, and it will become a cold air flow when it reaches the surface of the object. The evaporation of dry ice will not damage the mold. In addition, dry ice is made of carbon dioxide gas, and there will be no water residue when it evaporates, but it will directly become carbon dioxide gas. There is no need to worry that it will evaporate and cause relative damage to the mold. Dry ice is non-toxic and does not produce chemical reactions under normal conditions. Secondly, the carbon dioxide used to make dry ice comes from the air itself, and will not cause secondary pollution to the environment.
