Uses of dry ice cleaning machines
Release time:2018-06-14
Scope of dry ice cleaning applications: Industrial molds—including tire molds, rubber molds, polyurethane molds, polyethylene molds, PET molds, foam molds, injection molds, alloy die-casting molds, hot core boxes and cold core boxes used in casting—can effectively remove residual resin, degraded release coatings, carbonized mold release agents, oil stains, and unclog vent holes. After cleaning, molds regain their original luster and shine. This online cleaning process eliminates the need to cool down or disassemble the molds, thereby avoiding the corrosion and damage caused by chemical cleaning methods, mechanical damage and scratches from mechanical cleaning methods, and the precision degradation resulting from repeated assembly and disassembly. Most importantly, it eliminates the two most time-consuming steps: dismantling the mold and waiting for it to cool down.
Scope of application for dry ice cleaning:
Industrial molds
Tire molds, rubber molds, polyurethane molds, polyethylene molds, PET molds, foam molds, injection molds, alloy die-casting molds, hot core boxes and cold core boxes for casting—these can effectively remove residual resin, degraded release coatings, carbonized film residues, oil stains, and unblock vent holes. After cleaning, the molds regain their original luster and shine as if they were brand-new. This online cleaning process eliminates the need to cool down or disassemble the molds, thereby avoiding the drawbacks of chemical cleaning methods—such as corrosion and damage to the molds—and mechanical cleaning methods—such as mechanical wear and scratches—as well as the precision degradation caused by repeated assembly and disassembly. Most importantly, it eliminates the two most time-consuming steps: dismantling the mold and waiting for it to cool down. As a result, downtime can be reduced by approximately 80% to 95%.
Petrochemicals
Cleaning of equipment such as main blowers, air compressors, flue gas turbines, steam turbines, and blowers, as well as removal of coke and carbon deposits from various heating furnaces and reactors. Cleaning polyvinyl chloride resin from heat exchangers; removing oil stains, rust, hydrocarbons, and surface contaminants from pressure vessels including compressors, storage tanks, and boilers; cleaning reaction vessels and condensers; performing complex machinery decontamination; and descaling furnace tubes, among other tasks.
Food and pharmaceutical
It can effectively remove baked-on residues, sticky substances, grease stains, and mixtures of raw ingredients that have not yet been baked from ovens. It is highly effective for cleaning ovens, mixing and blending equipment, conveyor belts, molded products, packaging machinery, oven racks, baking trays, containers, rollers, inner walls of freezers, cookie-baking racks, and more. The benefits of dry ice cleaning include: eliminating the use of harmful chemical agents, preventing production equipment from coming into contact with hazardous chemicals and generating secondary waste; inhibiting or removing bacteria such as Salmonella and Listeria, ensuring more thorough disinfection and cleanliness; avoiding damage to electronic equipment that can occur with water-jet cleaning; minimizing equipment disassembly; and reducing downtime.
Printing industry
Removing ink buildup is challenging, and accumulated ink on gears and guideways can lead to poor print quality. Dry ice cleaning effectively removes a wide variety of oil-based and water-based inks as well as varnishes, thoroughly cleaning grease, ink deposits, and dyes from gears, guideways, and nozzles. This method avoids the discharge of hazardous waste and solutions, as well as potential personnel injuries caused by dangerous solvents. In the power industry, dry ice cleaning can be used to clean power boilers, condensers, and various types of heat exchangers. It allows for live-load cleaning (below 37 kV) of indoor and outdoor transformers, insulators, switchgear cabinets, and wires and cables—all while they remain energized. Components such as generators, electric motors, rotors, and stators can be cleaned without any damage. For steam turbines and turbines, dry ice cleaning efficiently removes rust, hydrocarbons, and sticky powders from impellers and blades, eliminating the need to disassemble the blades and saving time by avoiding the re-balancing required after blade reassembly.
Automotive industry
Clean door panels, roof linings, interiors, and undercarriages without leaving any water stains or causing water pollution. Also suitable for carburetor cleaning and paint removal from vehicle surfaces; effectively removes engine carbon deposits. When dealing with carbon buildup, traditional chemical treatments take a long time—typically at least 48 hours—and the chemicals used can be harmful to human health. In contrast, dry-ice blasting can completely eliminate carbon deposits in under 10 minutes, saving both time and costs while achieving a 100% descaling rate.
Electronics industry
Cleaning internal grease and dirt from cleaning robots and automated equipment; removing residues from integrated circuit boards, post-soldering flux, contaminated coatings, resins, solvent-based coatings, protective layers, and photoresist etchants on printed circuit boards.
Aerospace
Pre-processing procedures for missile and aircraft painting and final assembly; paint removal from composite molds and special aircraft; engine carbon deposit cleaning; maintenance and cleaning (especially in the landing gear and wheel well areas); paint removal from aircraft exteriors; jet engine conversion systems. Can be applied directly to the airframe, saving time.
Shipbuilding industry
The hull; seawater intake valve; seawater condenser and heat exchangers; engine room, mechanical and electrical equipment—these are cleaned more thoroughly than with conventional high-pressure water jet cleaning.
Nuclear industry
If traditional cleaning methods such as water, sandblasting, or chemical cleaners are used to clean nuclear industry equipment, the media—whether water, sand, or chemicals—can become contaminated with radioactive elements. Handling these secondarily contaminated media requires both time and financial resources. In contrast, the dry-ice cleaning process involves directly spraying dry-ice pellets onto the surface to be cleaned; the pellets sublimate instantly, eliminating any risk of secondary contamination. All that needs to be handled subsequently is the waste material—such as nuclear-contaminated deposits—that has been removed during the cleaning process.
General manufacturing
Cleans oil stains, paint, ink, adhesives, carbon deposits, asphalt, surface rust and grime, industrial fans, welding slag, electroplating coatings, and more. Also suitable for other industries and fields.
