The dry ice cleaning machine is an advanced cleaning equipment that utilizes solid carbon dioxide particles (dry ice pellets) for cleaning. This cleaning method has many advantages over traditional washing, chemical cleaning or mechanical cleaning, and its principle and working method are very unique.
First, let's take a look at the properties of dry ice. Dry ice is solid carbon dioxide that does not melt into a liquid state when exposed to room temperature, but instead directly changes from a solid state to a gaseous state, a process known as sublimation. This property allows dry ice to be transformed directly into a gaseous state during the cleaning process, leaving no moisture or chemicals behind, removing dirt without damaging the surface.
Dry ice cleaning machines work by ejecting high-velocity dry ice particles to impinge on the cleaning target surface. Inside the equipment, solid carbon dioxide particles are heated to high pressure and then accelerated through nozzles to form a high-velocity air stream and drive the dry ice pellets at the same time. When these high-speed dry ice particles come into contact with the surface, they quickly sublimate into carbon dioxide gas due to temperature differences, creating an instantaneous impact force that will instantly impact and remove the dirt from the surface. This process is often referred to as the "thermal shock" effect.
In addition to the thermal shock effect, dry ice cleaning also has a mechanical shock effect. The high-velocity blasting of dry ice particles creates an impact that will help remove dirt to some extent while also helping to remove rust or oxides from the surface.
The advantage of dry ice cleaning lies not only in its cleaning results, but also in its operational safety and environmental friendliness. The use of dry ice cleaners does not require the use of water or chemical cleaners, so no chemical waste or wastewater is generated, reducing the negative impact on the environment. At the same time, the need for post-processing is also reduced because the dry ice pellets can evaporate directly after the cleaning process.
To sum up, the working principle of the dry ice cleaning machine is based on the high-speed spraying of dry ice particles, which uses the effect of thermal shock and mechanical shock to remove dirt, and at the same time has the characteristics of environmental protection, high efficiency and safety. This makes dry ice cleaning an increasingly popular cleaning method and is widely used in a wide range of cleaning needs in a variety of fields.
