Dry Ice Cleaning System_BT01
Description
Specialized Company for Designing, Manufacturing, and Operating Dry Ice Cleaning
Dry Ice has a higher cleaning efficiency than other cleaning machines. It shows outstanding cleaning ability even against hard-to-clean objects. Moreover, its maintenance and operation expenses are cheap.
It causes no damage to the parent metal.

Key Features
1. There is a big difference in temperature.
The temperature of ice is 0°C, whereas the temperature of dry ice is -78.5°C.
It has a very low temperature, and because it has sublimation, which changes directly to a gas without going through a liquid state, it absorbs the surrounding heat and lowers the temperature rapidly.
Therefore, it is widely used as a coolant to keep the surrounding material cold (fresh food storage, ice cream cold storage, etc.).
2. Unlike ice, it does not contain water.
When dry ice is left outside, it sublimes and disappears without leaving any water, which proves that there is no moisture. For this reason, it is called Dry-Ice, which means 'dry ice'.
3.hardness is very low.
Although there is a slight difference depending on the temperature and size, dry ice is more easily broken than ice and has a hardness of less than or equal to gypsum (2 mohs).
4. The change of state at room temperature and pressure is very different.
This is because ice slowly melts and turns into water, whereas dry ice is a representative sublimable material that expands in volume without going through a liquid state and turns into a gas.

Need for Dry ice Cleaning
Need for industrial cleaning / decontamination
• Dirt, dust, sludge radioactive materials and pollution are generated when handing various industrial manufacturing processes and industrial facilities.
• Economic losses due to waste of manpower, delay in construction delivery, and harmful substances are generated.
• Necessity of spraying method using tools
-> Spraying : It removes scale, rust, coating film from the base material by spraying the water with sand, steel, shot, grit, silica and other abrasives with compressed air.
Major Injection Method Status and Issues
• Sand blasting method : Strongly spraying fine sand particles with compressed air, etc.
-> A large number of workers suffer from silicon pneumonia in Turkey's and spraying workshop (Hankyoreh 21-2010.07.02)
• Conventional blasting methods, such as sand blasting, cause secondary pollutants (environmental destruction and harmful / carcinogenic substances, etc.) and damage to the base material, resulting in economic losses.
• It is an indispensable requirement for eco-friendly dry ice blast cleaning to improve working environment, minimize environmental damage and economic losses.



Dry Ice Cleaning Method and Characteristics
• Dry ice pellets with hardness of 2 Mohs are sprayed under 5 atmospheres collide with foreign substances in the speed of 300~800 m/s.
• Dry ice pellets are quickly frozen under super low temperature and give a thermal shock from temperature difference between cleaning target and pellets.
• Repeated shrinkage and cracking take place due to abnormal thermal expansion coefficient of the foreign substance on the material.
• The volume expands by 800 times due to property of dry ice that permeated through the cracks.
• Dry cleaning is sanitary without humidity and doesn't generate wastes or waste water causing contamination.
• In case of molds, dry ice pellets can be sprayed directly on the machine without the need for re-setting after cleaning.
