CO2 industrial cleaning method - Overview and applications

8/03/2022

CO2 industrial cleaning or dry ice cleaning is one of the services that play an important role and can be applied well in many industries today.

CO2 industrial cleaning - Definition, mechanism of action and application in industry

CO2 cleaning is an industrial cleaning method applied to many industrial production types, and this is the most advanced cleaning technology available today.

CO2 cleaning - Industrial cleaning method using low temperature

Dry ice industrial cleaning or CO2 cleaning is a low-temperature cleaning method using CO2 (dry ice) molecules that are accelerated at supersonic speeds. The extremely low temperature and high speed of these CO2 dry ice molecules create collisions like micro "blasts" on the surface to be cleaned. This helps to break down the structure of dirt on the surface of the object.

Find out the way of CO2 industrial cleaning method works

Low-temperature dry ice (about -79 degrees Celsius) is sprayed from the dry ice machine. It touches the surface to be cleaned, due to the reaction to cold temperatures, the dirt and the surface to be cleaned shrink at different rates, creating cracks in the surface of the dirt. Solid CO2 molecules moving at ultrasonic speed collide strongly with the surface of the dirt, creating more cracks on the surface.

Through the cracks, micro molecules of dry ice break into the dirty surface's material and come inside the crack. This warmer surface causes the solid CO2 to turn into a gas. CO2 has a volume about 800 times larger than the solid-state. When this layer of gas forms underneath the dirt, it will create tiny explosions and loosen this sticky layer of dirt. That is the working mechanism of CO2 cleaning technology.

The application of CO2 industrial cleaning method in the industry

CO2 industrial cleaning is applied in most industrial production fields such as plastic processing, rubber molding, extrusion, automobile, food processing, and semiconductor technology. , plating, printing, electricity/electronics,... In addition, other industries such as space technology, space, aviation, paper processing, pollution recovery and treatment also need to use technology.

Advantages of CO2 industrial cleaning for industrial equipment

The CO2 industrial cleaning is applied in many fields thanks to the following benefits:

High efficiency, cleaning even complex components: CO2 cleaning can be applied to even complex, detailed parts of the device. This is not easy with conventional cleaning methods.
Dehydrated CO2 cleaning process: During the CO2 dry ice cleaning process, there will be no residual wastewater or other abrasives. The dirt after the process can be easily collected, safe, and non-flammable.
Non-abrasive: CO2 dry ice pellets do not wear down the surfaces to be cleaned. Therefore, production machinery and tools are not affected in quality after the CO2 cleaning process.

No need to dismantle machines and production lines: The cleaning process can be carried out as soon as the equipment and parts are still on the machine. No need to disassemble parts for cleaning. So you save a lot of time and effort in the installation and operation of the machine.
Do not use chemicals: This is a safe and environmentally friendly method of cleaning industrial equipment. During the process, we do not need to use any additional chemicals. Not only helping to protect the environment, but cleaning CO2 does not need to cost more to treat toxic chemicals, solvents, or other wastes.

With many advantages in cleaning industrial equipment, CO2 industrial cleaning is today's most widely used method. This method brings good efficiency and ensures safety for the environment.
