The use of liquid CO2 compressed into small snow pellets offers many positive characteristics due to the poor conductivity of CO2. After blasting, there are no wastewater, chemicals or blasting agent residues requiring disposal, as the pellets dissolve and return to the atmosphere as CO gas, leaving only the containment behind. Dry ice blasting often allows the company’s production equipment to be cleaned while in operation.
Although dry ice blasting Small Business mechanism has not been fully clarified and this technology has a wide range of applicability, there are not many publications which would deal with dry ice blasting. Therefore, the main goal of this review is to provide a systematic overview of dry ice blasting applications in industrial surface cleaning. From the industrial point of view dry ice blasting is mostly used in plastic, rubber and foam manufacturing and in automotive industry. The benefits outweigh the drawbacks of this technology as evidenced by the large number of applications mentioned in this study. However, with regard to the drivers and barriers of dry ice blasting, it is necessary to assess its suitability for a specific process and find a tailor-made solution. Environmental impact assessment of the DIB process should be one of the main directions for future R&D.
Unlike other blasting media, dry ice leaves no secondary waste because the media evaporates on impact. The only cleaning to be done after blasting is the cleaning of whatever was removed. The dry ice, although hard in appearance, does not rely on its abrasive properties for effective cleaning.
Laser cleaning provides a variety of solutions to fit different needs. From portable handheld solutions to larger, 1,000-watt automated products, laser cleaning provides a durable clean for a reasonable and low price. It doesn’t require a special environment to store equipment, and laser cleaning is about 15 times faster than abrasive hand cleaning and eight times faster than dry ice blasting. That means that you can clean your products in less than half the time.
Hydrocarbon removal requires liquid CO2, an excellent solvent for nonpolar hydrocarbons. Impact forces allow the pressure to rise above 0.5MPa , leading to liquid CO2 formation and thus solvent cleaning. Nozzle to sample distance has a role in hydrocarbon removal as the snow velocity must be high enough for the impact pressure to rise above 0.5MPa . Other applications included cleaning of complex parts, the cleaning of nonmetallic parts, and the cleaning of objects prior to the application of optical and thermal protective coatings. For applications in Department of Defense facilities, waste mitigation eliminated more than 155,000kg of waste annually, which resulted in estimated savings of more than US$600,000 per year. Induspray has successfully used dry ice blasting techniques for years, and can safely and effectively use it in your project with excellent results.
Dry ice blasters blast carbon dioxide pellets or MicroParticles at supersonic speeds using compressed air. These pellets/particles then sublimate on impact and lift dirt and contaminants off the underlying substrate. Cleaning with dry ice allows food processing equipment to be cleaned without scrubbing or scraping; reducing water waste and damage with equipment.
When the dry ice pellets hit target surfaces, it causes a process called thermo-shock. As the substrate temperature decreases, it becomes brittle, enabling the dry ice particle to break up failed paint and surface contamination. With dry ice blasting, soft CO2 pellets approximately the size of grains of sugar are propelled toward surfaces at supersonic speeds to safely remove paint and contamination. The CoolMaster accelerates the particles of dry ice to an extremely high speed combined with a jet stream of compressed air, and subsequently blasts them on the object that needs to be cleaned. This creates 3 different effects which enable an optimal cleaning procedure.
