Speaking of dry ice, most people think of the dreamy white "fairy air" on the stage. It is formed by the sublimation of dry ice to absorb heat and water vapor to liquefy when cold. It is a beautiful "spectacle". Similarly, dry ice can also be used for artificial rainfall, fire extinguishing, etc., which brings great help and convenience to people's lives. However, there is one use you may not have heard of, that is, it is commonly used for dry ice cleaning of mechanical equipment and parts.

What is dry ice cleaning?

Dry ice cleaning is a method similar to sandblasting cleaning. It uses dry ice in the form of particles instead of traditional sandblasting media, which can efficiently remove scale and complete cleaning without abrading the surface of the object and without secondary pollution.

What is the principle of dry ice cleaning?

1. Driven by the kinetic energy of compressed air, dry ice particles impact dirt at a high speed of 150m/s; (mechanical effect 70%)
2. The dirt is hardened and brittle under the low temperature of -79℃; (low temperature effect 20%)
3. When the dry ice particles touch the surface of the object, they will blast (sublimate into gas) instantly, and the blasting force will strip the contaminants from the surface. (Sublimation effect 10%)
4. Compared with the traditional, what are the advantages of dry ice cleaning?
5. Online cleaning, no need to disassemble

The dry ice cleaning process is completely dry and non-conductive. It can avoid the tedious disassembly and debugging work in the traditional sense, and directly penetrate into the gaps and grooves to clean the corners.

1. Flexible cleaning, no wear
2. Dry ice blasting machine will not cause any abrasion on the surface of the object, and does not affect the accuracy of the equipment, and can even be suitable for efficient descaling of sensitive and fragile surfaces.
3. Low cost, high cost performance

Dry ice cleaning has low raw material consumption cost, short equipment downtime, less sewage treatment and less mold trials, and the overall cost and efficiency are better than traditional methods.

1. Green environmental protection, no pollution

No chemical agents and sand abrasives are used in the cleaning process, and there is no residue after cleaning, which will not cause secondary pollution and damage.

What are the main application areas of dry ice cleaning?

Dry ice cleaning/dry ice blaster is mainly used in food, mold, chemical, printing, paint, machinery and automation industries. For example, the Kach IB series dry ice cleaning machine has excellent performance, complete accessories, strong stability and high cost performance. At the same time, the complete solution of dry ice cleaning system composed of dry ice machine, ice maker, incubator and various accessories can also meet the customized needs of different industries.

1. Food industry

Dry ice cleaning can remove baking residues, gelatinous substances, oil stains and fresh products in the oven. Mixing equipment, conveyor belts, molded products, packaging equipment, hobs, hobs, containers, rollers, freezer inner walls, and biscuit ovens Strips, etc., to avoid contact of harmful substances in food production with bacteria, thoroughly disinfect and clean, and extend the service life of equipment.

2. Mold industry

Dry ice cleaning is suitable for tire molds, rubber molds, polyurethane molds, polyethylene molds, PET molds, foam molds, injection molds, alloy die-casting molds, casting hot core boxes, cold core boxes, and can remove residual resin, failed release layers, Carbonized film agent, oil stains, vent holes, etc., without cooling and disassembling the mold, can reduce mechanical damage, reduce accuracy and shorten the time of 80%-95%, making the mold bright as new.

3. Chemical Industry

Dry ice cleaning can handle the coking and coking on main fans, air compressors, hoods, steam turbines, blowers, various heating furnaces, reactors and other equipment, polyvinyl chloride resin on heat exchangers, compressors, storage tanks, boilers, etc. Oil stains, rust stains, hydrocarbons and other dirt on various pressure vessels, stains on reactors, condensers, complex machine bodies and furnace tube cleaning, and dirt on electric boilers, condensers, and various heat exchangers.

4. Printing and machine paint industry

Dry ice cleaning can effectively remove difficult-to-handle printing press ink, ink accumulation on gears and rails, various oil-based and water-based inks and varnishes, as well as oil stains, ink accumulation and dyes on gears, rails and nozzles, so as to avoid affecting printing quality And the discharge of hazardous waste and solution can cause injury to personnel.

5. Machinery industry

Dry ice cleaning can be used for cabins, engine compartments, and under-vehicle oil stains, etc., without causing water pollution; at the same time, it can also clean car carburetor and surface paint, remove engine carbon deposits, so that it takes more than 48 hours to clean thoroughly. It can be shortened to 10 minutes; in addition, the ship hull, seawater suction valve, seawater condenser, heat exchanger and engine room, mechanical and electrical equipment, etc. can also be cleaned with dry ice, which is cleaner than general high-pressure cleaning.
