How Does Dry-Ice Blasting Work

In industrial cleaning, it would not be possible to use the same method because every job project has different treatment needs. If it worked for the first project, it does not mean that it will work with the other one. With this, it is important to know when dry-ice blasting considered being the best solution.

Dry-ice cleaning is also a form of abrasive blasting that utilized to prepare the surface and remove impurities such as dust and rust to make it smooth before coating. This method uses dry-ice that is the solid form of carbon dioxide blasted through the surface with pressurized air. It is an alternative to sand or glass beads because it is softer and does not ruin the entire surface. Upon impact to the surface, the ice almost immediately sublimates and leaves no chemical residue unlike solvent-based cleaning agents available in the market.

Is dry-ice blasting effective in cleaning?

Dry-ice cleaning eliminates the need of water in the process. Thus there would be no place for molds and bacteria to grow. The ice absorbs heat from the surface causing the dirt to flake off easily. It cleans hard to reach areas. It is aggressive enough to clean heavy rust and can be sensitive enough to clean delicate equipment.

 

Benefits of dry-ice blasting

  • No water
  • No chemicals
  • Non-toxic
  • Non-abrasive
  • Non-flammable
  • Non-conductive
  • Safe for equipment
  • Approved and safe for the food industry, it can even decontaminate surfaces from salmonella, e. Coli, listeria, and other microorganisms.
  • Can be utilized without harming mechanical or electrical parts
  • It allows most items to be cleaned in place, often no disassembling and reassembling cost
  • Reduced downtime
  • Reduced waste disposal, as dry-ice sublimates, the only left to clean is the removed debris.
  • It cleans faster and better than other agents, no dry time or cooling time required.
  • Environment-friendly and contains no contaminants
  • Extends the life of the equipment, it does not abrade, wear, or erode material.
  • Reduced cost, with all the above benefits, it can remove all adverse impact of clean-up operations. The downtime cost, labor cost, and waste disposal cost.

 

Things to remember in dry-ice cleaning

  • Blasting would send dust to the air so the operator and people nearby should wear a mask.
  • Dry-ice has a temperature of -79°C and can cause skin burn so wear protective clothing, gloves, and eye protection.Industrial Coating
  • You need to wear hearing protection as the level of noise may exceed maximum permissible level depending on the blasted object.
  • Before blasting, secure or remove all loose objects that can deflect by the pressure of the dry-ice.
  • Dry-ice sublimates into carbon dioxide gas, it can be suffocating in confined and poorly ventilated areas so the application should be in an open area. Use exhaust vents to remove the gas efficiently.
  • It is recommendable to have dry-ice blasting service from a professional as they have the proper equipment and knowledge about application cautions.
