Working Principle
Dry ice cleaning technology is a relatively advanced cleaning method in the cleaning industry
and has been widely used worldwide.
Working Principle: Dry ice particles are accelerated by high-pressure airflow and are
propelled at high speed onto the surface to be cleaned using a specially designed blasting gun.
Upon impact with the surface, the dry ice particles undergo rapid surface heat exchange,
causing the solid CO2 to sublime rapidly into gas. Within a fraction of a second, the volume
of the dry ice particles expands by 800 times, amplified by the impact force of high-pressure
air, resulting in a "micro-explosion" on the object's surface. The gaseous CO2 produced by the
"micro-explosion" dissipates, leaving no secondary residue. The remaining dirt, affected by
the low temperature, becomes brittle and is directly dispersed by the high-pressure airflow.
