Dry ice blasting service has been used in various industries, so do you know that there are three principles of dry ice blasting service? Below we will briefly introduce the three major principles of dry ice blasting for you.

First, a strong impact

The dry ice hits the surface to be cleaned at high speed, the dissipation of the kinetic energy of the impact and the extremely fast heat transfer between the dry ice particles and the cleaned surface cause carbon dioxide to change from a solid state to a gaseous state in an instant.

Second, the micro-explosions carry the dirt away from the surface of the object

When the dry ice particles drill into the cracks of the dirt, they are gasified within a few thousandths of a second, and their volume expands nearly 800 times in an instant, thus taking the dirt away from the surface of the object.

Third, the phenomenon of thermal shock, which affects the mechanical properties of the adhered dirt

Two different materials with different thermal expansion coefficients, the temperature difference between them will destroy the bond between the two materials. The temperature of the dry ice particles is extremely low (-78.5°C), and the dry ice particles impact the surface of the treated object, causing the dirt to freeze to embrittlement and burst, resulting in "cracking" or thermal shock, which affects the mechanical properties of the adhered dirt. The dry ice decontamination process uses compressed air as power to shoot dry ice sand onto the surface of the object to be treated. However, to achieve the purpose of cleaning, it does not rely solely on strong wind pressure, but uses the low temperature of dry ice. Therefore, when cleaning electronic products, only need to adjust Low wind pressure will not damage the structure of the product; if we want to clean up stubborn dirt, we can also increase the air pressure to cooperate with the freezing characteristics of dry ice to achieve a two-pronged effect.
