Product Description
What is dry ice?
Dry ice: White solid carbon dioxide CO2 at -78.5 ºC, usually condensed into a colorless liquid at a pressure of 62.50 bar, and rapidly solidified under low pressure by throttling and depressurization.
Physical properties: White crystal, easily sublimated at room temperature, high heat of vaporization, can rapidly lower the surrounding temperature when sublimated at atmospheric pressure. Therefore, dry ice will liquefy and even further condense water in the air when sublimated
Steam, formed by water vapor droplets or small ice crystals attached to dust in the air, forms the visible white smoke. The crystal structure of dry ice is simple cubic and belongs to molecular crystals. A single carbon dioxide molecule
Stacking dry ice crystals in different orientations at the vertices and centers of the cube.
Chemical properties: Dry ice is chemically stable, odorless, non-toxic, non combustible, and does not support combustion. But if the carbon dioxide content in the air is too high, it can stimulate the respiratory system, cause accelerated breathing, and pose a risk of suffocation
(i.e. hypoxia). Carbon dioxide has high thermal stability (only 1.8% decomposition at 2000 ºC). Dry ice belongs to acidic oxides and has the properties of acidic oxides. It reacts with water to form carbonic acid.
How is dry ice made?
Liquid carbon dioxide is extracted from the liquid carbon dioxide storage tank and sprayed into the ice pressing chamber of the dry ice machine. The throttling through the nozzle produces a large amount of gas, carbon dioxide, and snowflake like dry ice solids. When solid dry ice accumulates
After reaching a certain quantity, the hydraulic system is activated, and the piston compresses the snowflake shaped dry ice into dry ice cubes and squeezes them out from the die end. At this point, the rotating blade at the end of the dry ice machine is activated, shattering the elongated dry ice column into pieces
Dry ice pellets of required length
There are three main principles of dry ice cleaning:
Energy transfer: Dry ice impacts the cleaned surface at high speed, dissipating the kinetic energy of the impact. The dry ice particles undergo extremely rapid heat transfer with the cleaned surface, causing carbon dioxide to sublime instantly. The dirt rapidly cools, contracts, and becomes brittle
Being washed down.
Low temperature cracking ": Two different materials with different coefficients of thermal expansion, the temperature difference between them will destroy the bond between the two materials. Dry ice pellets (-78.5 ºC) impact the surface of the treated material to freeze the dirt until it becomes brittle
Melting and bursting, producing "cracks" that affect the mechanical properties of adhering dirt, causing dirt to fall off.
Micro explosion ": After dry ice particles penetrate into dirt cracks, they sublimate within a few thousandths of a second, instantly expanding their volume by 600-800 times, and peeling the dirt off the surface of the object.
Brief explanation of the industry application of dry ice cleaning
Dry ice cleaning is widely used to clean various surface stains such as metal, molds, production equipment, ancient cultural relics, etc. The cleaning process does not require cooling or disassembling the mold, avoiding corrosion and damage to the mold caused by chemical cleaning methods
The mechanical cleaning method has disadvantages such as mechanical damage and scratches to the mold, as well as decreased mold accuracy caused by repeated loading and unloading. Here are some examples:
1.Petrochemical industry: Dry ice cleaning technology can be used for cleaning rust and dust on equipment such as main fans, air compressors, exhaust fans, steam turbines, and blowers in the petrochemical process (without the need to remove the blades, eliminating the need to recalibrate the blades for dynamic leveling)
Weighing steps); Removal of coking and coking in various heating furnaces, reactors, etc; Clean the polyvinyl chloride resin on the heat exchanger; Remove oil and rust stains from equipment such as compressors, storage tanks, boilers, reactors, condensers, and complex machinery
And dust;
2.Power system: It can directly clean indoor and outdoor transformers, insulators, distribution cabinets, wires, and cables with live load (below 37 kV); Generator, motor, rotor, stator and other components are cleaned without damage;
3.Food production: Dry ice cleaning can successfully remove baking residue, gelatinous substances, oil stains, and fresh product mixtures before baking in the oven. Effectively clean ovens, mixing and stirring equipment, conveyor belts, molded products
Packaging equipment, furnace racks, furnace plates, containers, rollers, inner walls of refrigerators, biscuit grates and other equipment;
4.Automotive and shipping industry: Cleaning car door covers, canopies, carriages, and bottom oil stains without water residue, will not cause water pollution; Cleaning of car carburetors and removal of paint from car surfaces; Clean up engine carbon deposits on vehicles and ships (chemical agents)
The processing time is long, requiring at least 48 hours of use, and the medication is harmful to the human body. Dry ice cleaning can completely solve the problem of carbon deposition within 10 minutes, saving time and reducing costs, with a descaling rate of up to 100%;
Clean the hull, seawater intake valve, seawater condenser and heat exchanger, engine room, mechanical and electrical equipment, etc;
5.Aerospace field: pre production processes for missile and aircraft painting and final assembly; Paint removal for composite molds and special aircraft; Engine carbon cleaning; Maintenance and cleaning (especially in the landing gear wheel compartment area); Paint removal of aircraft shells;
Jet engine conversion system. Can work directly on the body, saving time;
6.Printing industry: Dry ice cleaning can remove various oil-based and water-based inks and varnishes, clean oil stains, ink deposits, and dyes on gears, rails, and nozzles, not only effectively ensuring the quality of printed products, but also
Printing equipment is not worn out.
Cultural relic cleaning: Dry ice cleaning technology can efficiently and non destructively clean pollutants such as soil, soluble salts, mold, and sedimentary films attached to the surface of cultural relic specimens. Compared to traditional physical and chemical cleaning methods, it not only improves
Cleaning efficiency and quality are also more friendly to the environment and the health of workers.
Cleaning method and working principle of CHIRUI pellet dry ice cleaning
Similar to spraying steel sand, glass sand, plastic sand, and baking soda, dry ice blasting medium accelerates dry ice particles in high-pressure airflow and impacts the surface to be cleaned. Dry ice cleaning
The uniqueness lies in the fact that dry ice particles vaporize at the moment of impact. The momentum of dry ice particles disappears at the moment of impact. Rapid heat exchange occurs between dry ice particles and the cleaning surface. cause
Solid CO2 rapidly sublimates into gas. Dry ice particles expand nearly 800 times in volume within a few thousandths of a second, causing a "micro explosion" at the impact point. Due to the volatility of CO2
Sent it out, the dry ice cleaning process did not generate any secondary waste, leaving only the dirt that needs to be collected and cleaned.
