Dry Ice Blaster Cleaning Machine for New Energy Battery or Motor Compartment of Electric Vehicle Cleaning

•  Product introduction

What is dry ice?

- Dry ice is an ERA, FDA and USDA certified cleaning medium. Dry ice is solid carbon dioxide, obtained by condensing carbon dioxide into a colorless liquid at a pressure of 6250.5 kPa, and then rapidly solidifying at low pressure. Dry ice low temperature -78.5°

What is  dry ice cleaning / blasting machine?

Dry ice cleaning machine is a kind of cleaning equipment. The cleaning system sprays the dry ice particles of the dry ice cleaning machine to the working surface to be cleaned through high-pressure air, and uses the physical reflection of temperature difference to make different substances detach at different shrinkage speeds. When the dry ice particles at -78 degrees Celsius contact the surface of the dirt, an embrittlement explosion will occur, which will shrink and loosen the dirt, and then the dry ice particles will instantly vaporize and expand by 800 times, generating a strong peeling force, which quickly removes the dirt. It completely falls off the surface of the object, so as to achieve 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 blasting itself does not create carbon dioxide.

Working principle:

Dry ice cleaning is to spray dry ice (solid CO2) onto the surface of the workpiece at supersonic speed, and the dry ice sublimates instantly, producing an impact micro-explosion effect, the stains are contracted by cold, and the strong air wave peels off the stains from the surface of the workpiece to achieve cleaning.

What are the advantages of dry ice cleaning?

1. Reduce downtime: shorter downtime, longer production time;

2. Non-destructive cleaning: Dry ice is a soft medium that will not damage the substrate;

3. The operator is safer: it will not bring health risks to the operator;

4. Improve efficiency: online cleaning equipment, the mold does not need to be cooled and disassembled;

5. Improve product quality and yield: more thorough cleaning of machinery and molds, higher product quality;

6. Non-toxic and non-conductive: Dry ice is a food-grade medium and can be used safely for commercial purposes;

7. No secondary pollutants: Dry ice cleaning will not produce secondary pollutants, residues or moisture;

8. Green and environmental protection: Dry ice is made of recycled carbon dioxide and will not emit additional carbon dioxide into the atmosphere;

9. Use labor more efficiently: This process reduces the time, labor, and resources required.

Dry ice cleaning for buses are mainly used in:

• Pure electric bus
• Hybrid electric bus
• Conventional bus

In order to adapt to the application of EFI engines and new energy electric vehicles in public transport enterprises, the cleaning equipment is upgraded and updated, which can be cleaned online without affecting the operation. It has the technical advantages of fast decontamination, environmental protection, instant gasification, no residue, no secondary pollution, non-destructive decontamination, no damage to the engine, and no damage to electronic equipment.

For example, dry ice cleaning for the bus inner parts cleaning on New energy battery/ motor compartment,Motor part,Battery part, Regular bus rear cabin etc.

• What problems can be solved by dry ice cleaning on electric automobiles?

1. Solve the problem that electric buses cannot be washed with water and the insulation value of vehicles decreases due to the accumulation of dust and wet weather. It is well received by public transport companies and from environmental protection departments and all sectors of society.

2. Solve the damage to the engine, wiring harness plug-ins, electronic components, computer boards, sensors, etc. caused by the inability of traditional water-washing to clean pure electric buses for enterprises. In particular, the problems of washing the engine with water, labor and sewage discharge after cleaning are difficult.

3. Use the characteristics of dry ice to make the dirt remaining on the engine surface fall off from the engine to the ground. After cleaning, you only need to clean the site, which saves time, effort, and water washing and discharge treatment costs, and meets environmental protection requirements.

• Dry ice cleaning car knowledge quiz: 

1. Q: Why does dry ice cleaning have no effect on the circuit of the engine?

    A: This is due to the properties of CO2, neither solid dry ice nor gaseous CO2 conduct electricity.

2. Q: Can dry ice cleaning be electrified?

    A: Electric cleaning has become a highlight of dry ice cleaning. Because dry ice cleaning is a non-contact cleaning method, dry air can be used for electrified cleaning during the cleaning process, and the dry ice particles are directly sublimated into CO2, which is a non-conductive gas.

3. Q: Will the low temperature spraying of -78℃ dry ice affect the engine and surrounding devices?

    A: Through the test, after the general metal surface is blasted with dry ice for 30 seconds, the temperature of its 0.5mm depth surface is reduced by 9-10 ℃. Dry ice cleaning is only a non-contact and rapid movement on the surface of the object to be cleaned, and the temperature change is only about 3~5℃, so dry ice cleaning will not cause a large temperature change to the cleaning object, nor will it cause any damage to the components around the engine. influences.

4. Q: The engine of the car that has just been run is hot, can it be cleaned?

    A: Yes! Although the temperature of the dry ice sprayed reaches a low temperature of -78°C, due to the high efficiency and speed of dry ice cleaning, the local dry ice blasting time is short, the temperature difference caused by dry ice cleaning after rapid movement is small, and the blasting surface is large, so the dry ice blasting has little effect on the engine. And the effect of high temperature cleaning is better.
