Our company specializes in the production and sale of cleaning machines
Dry ice cleaning methods have developed rapidly worldwide. The cleaning system sprays dry ice particles from the dry ice cleaning machine onto the working surface that needs to be cleaned through high-pressure air. It utilizes the physical reaction of temperature differences to cause different substances to separate at different contraction rates. When dry ice particles at -78 degrees Celsius come into contact with the surface of dirt, they will become brittle and explode, causing the dirt to contract and loosen. Subsequently, the dry ice particles will instantly vaporize and expand 800 times. The product's powerful peeling force can quickly and thoroughly remove the dirt from the surface of the object, achieving a fast, efficient, safe and energy-saving cleaning effect. The carbon dioxide used in dry ice cleaning comes from industrial waste gas, high-altitude air separation, etc. Dry ice cleaning itself does not produce carbon dioxide.
With the advancement of industrial automation and the increase in labor costs, the downstream industries of dry ice cleaning equipment have entered a new round of prosperous cycle, which has led to an expansion of the market demand for dry ice cleaning equipment. The sales of the dry ice cleaning equipment industry have rebounded significantly, the supply and demand relationship has improved, and the industry's profitability has steadily increased. Meanwhile, under the national "12th Five-Year Plan" and the major policy of industrial structure adjustment, dry ice cleaning equipment is facing huge market investment opportunities, and the industry is expected to usher in new development opportunities.
Similar to steel grit, glass grit, plastic grit and soda spray, dry ice spray medium dry ice particles accelerate in a high-pressure gas flow and impact the surface to be cleaned. The uniqueness of dry ice cleaning lies in the fact that dry ice particles vaporize instantly upon impact. The momentum of dry ice particles vanishes at the moment of impact. Rapid heat exchange occurs between dry ice particles and the cleaning surface. This causes solid CO2 to rapidly sublimate into gas. Dry ice particles expand nearly 800 times in volume within a few thousandths of a second, thus causing a "micro-explosion" at the impact point. As CO2 has evaporated, the dry ice cleaning process does not generate any secondary waste. What remains to be collected and cleaned is only the dirt that has been removed.
