Dry ice cleaning or blasting is a modern technique of cleaning that is developed to meet the eco-friendly standards of cleaning. This method is quite similar to the techniques of sandblasting or steam blasting or high-pressure water blasting. Now raises the question “Why use this method when other similar methods still prevail?” This method is gaining wide adoption because it has proved to be more efficient and poses less damage to the surface being cleaned. Moreover, dry ice ejection does not cause any damage to the equipment being used as in most of the traditional methods, this damage occurs.
Dry ice cleaning takes place in the following simple steps:
- The ice pallets used in this cleaning methodology are shaved which means that ice density is reduced thereby making it delicate as compared to the solid ice blocks.
- The equipment used for dry ice cleaning can be single hose or two hose. The difference is that in the former, air inlet and ice outlet are through a single opening while in the latter, they are separate.
- When such dry ice is shot at the surface to be cleaned, its temperature varies from 109.3 °F to 78.5 °F. This causes the target surface impurities to shrink and lose connection from the surface.
- When some ice penetrates the upper surface, the warm inner surface causes this ice to be converted to CO2 gas, which possesses 800 times more volume and thus, the pressure, causes the outer impure surface to remove.
The benefits of using dry ice cleaning for industrial purposes include:
- This is a non-flammable and non-conductive, environmental friendly method of cleaning
- This technique is non-harmful and can thus be used for cleaning in the food industry
- Hospital cleanliness can be better ensured since this method is very clean and produces no secondary wastes
- No parts need to be disassembled for this method of cleaning
- No damage or danger of fire is likely to occur due to the electrical and mechanical parts
- Can have a number of general applications apart from the normal removal of oil, paints, dirt, resins and other adhesives
This method of cleaning the tough abrasive surfaces is becoming more and more popular these days with many industrial applications deploying this. However, the effectiveness of this system can take form only when the equipment is used properly and with expertise. The process may be noisy but the new machinery is better. Moreover, the handling of the equipment requires special skills and thus, needs professionals for that. Proper outlet precautions of carbon dioxide produced is also necessary to avoid any harm. So, the industries can use this system for cleaning but under the strict guidance of experts in the domain.
