DRY ICE BLASTING


[attachment=66609]


Introduction

Abrasive blasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants.

Applications:

-Cleaning before the dispatch of finished materials.
-Removing rust on the surface of metals.
-Removing marking from components.
-To provide sufficient surface roughness.
-Cutting patterns on shells, glass, fragile materials.


Traditional methods of Blasting

Sandblasting:
The act of propelling very fine (silicon)bits
of material at high-velocity to clean or etch a surface.

Problem: lung disease silicosis is caused by extended inhalation
of the dust created by sand.

Bleach / Chemical Treatment
Lot of time is wasted and no super quality cleaning.

Bead Blasting: Use of Glass as medium.

Crushed walnut shell blasting: Use of crushed walnut abrasives as a medium.


What is dry ice blasting ?

Dry ice blasting is similar to Sand blasting, Glass bead blasting, or Soda blasting.
Here also the medium is accelerated in a pressurized air stream to impact a surface to be cleaned or prepared


Benefits of Dry Ice Blasting

A non-abrasive, non-flammable and non-conductive.
Decrease in the cleaning time.
Environmentally-friendly ,clean .
Cleaning without disassembly without damaging.
Removes production residues, release agents, contaminants, paints, oils and bio films
Reduction in the waste volume
Not Hazardous for workers


Applications

Used for effective cleaning of any type and material in all industries (eg: ingot moulds, core boxes, injection moulds, high pressure die casting moulds, etc)

It is clean and approved for food industries.

it can be used without damaging active electrical and mechanical parts or creating fire hazards.

It can be used to remove production residues, release agents, contaminants, paint, oils and bio films.


Conclusion

Best method of cleaning.
Pellets do not cause any harm.
World over acceptation of DIB.
Initial investment becomes productive in 2 years.
Minimum maintenance.
