With the advancement of industrial automation and the increase in labor costs, traditional aqueous cleaning has shown some incompatibility. For example, the components on the product are not suitable for aqueous cleaning, and residues will easily appear on the product surface after aqueous cleaning. As an energy-saving and efficient new cleaning method, dry ice cleaning is gradually recognized by the market.
Dry ice cleaning machine is a cleaning system that uses high-pressure air to spray the dry ice particles of the dry ice cleaning machine onto the work surface that needs to be cleaned. Using the physical reaction of the temperature difference, the dry ice particles will cause embrittlement and explosion when they come into contact with the dirt surface, causing the dirt to shrink and loosen. When removed, the dry ice particles will instantly vaporize and expand 800 times, generating a strong peeling force to quickly and completely remove dirt from the surface of the object, thereby achieving a fast, efficient, safe and energy-saving cleaning effect.
The advent of dry ice cleaning machines has brought good news to the manufacturing industry. Dry ice cleaning machines have six advantages over other cleaning methods.
1. Cost saving: Because carbon dioxide is a component of the atmosphere, it is very convenient to access and cheap. The only power-consuming equipment is the air compressor. The dry ice evaporates directly during the cleaning process, and there is no cost of cleaning the cleaning medium.
2. Dry cleaning process: Unlike steam and high-pressure water cleaning, dry ice cleaning does not damage wires, control components, and switches. After cleaning, the possibility of equipment rusting is also greatly reduced compared with water cleaning. In food industry applications, dry ice cleaning greatly reduces the possibility of bacterial growth compared to water cleaning.
3. Environmental safety: CO2 is a non-toxic substance that meets the safety requirements of the United States Department of Agriculture (USDA), Food and Drug Administration (FDA), and Environmental Protection Agency (EPA). By replacing toxic chemical cleaning with dry ice cleaning, employees can fundamentally avoid chemical exposure. Since CO2 is heavier than air, ventilation and safety must be ensured when operating dry ice cleaning in enclosed spaces or sinking areas.
4. Extend the service life of equipment: Unlike sand, walnut shells, plastic pellets and other abrasive media, dry ice pellets are not abrasive. Dry ice cleaning does not damage the mold, does not destroy tolerances, and causes no damage to bearings or machinery. In addition, online cleaning avoids accidental damage during mold disassembly and assembly.
5. Efficient: Dry ice cleaning can be used for online cleaning, which greatly reduces parking time, avoids the shielding, cooling, disassembly and treatment of sewage and sand required by traditional methods, and saves drying time, thus achieving high production efficiency. and less time consumption.
6. Wide range of use: For different cleaning conditions, simply changing different dry ice cleaning nozzles can improve the cleaning working distance to meet different needs. It is easy to operate, safe, low cost, and has considerable overall benefits.
At present, dry ice cleaning has been widely used in industry, medical, aerospace, food, and power industries.
