What is Dry Ice Blasting? - Cold Jet

DuPont Imron was a premier, two part epoxy paint and worked well for painting aircraft. Until, I was told, someone found out that the hardener was carcinogenic.

Stripping aircraft of old paint is a delicate business, especially on control surfaces. Paint shops had to figure out a way to safely capture the old paint and satisfy EPA disposal regulations.

Dry Ice Blasting does it.

The dry ice, being super cold, shrinks the paint, apparently . stressing it. Subsequent hits by the ice knock it loose, all without harming the aluminum substrate.

The machine resembles a polishing buffer with a skirt around the base and the requisite hoses to feed the dry ice chips and vacuum away the debris.

One nice benefit is that the ice evaporates leaving behind just the debris which is bagged and shipped out.

I watched one application on a Beechcraft King Air elevator. It was fast! It did no harm to the skins. It was, however, an expensive system to acquire.

If you like an opportunity to see this technology in action I would suggest you Google for aircraft painting services, with emphasis on corporate sized aircraft. Or, check with the fixed base operator at the local airfield.

We used it in cleaning molds that make plastic parts and it works very well since it does not hurt the cavity plus there is no pollution. I cannot think of any negative factors from my experience except you need quite a bit of air to operate but that is true for any blasting. You should be very happy with the results also to be considered is soda blasting (baking soda) does not hurt the surface and again environmentally clean. You may have to do some hand scraping on heavy deposits just give it a try.

I have heard of people using walnut shells with good results as well. Although I have wondered where you would go to buy sacks of shells.

Dear Susui,

Please have a look to our homepage www.icetechworld.com

Let me know if you need further information

Look on the website www.cryonomic.com and its application page. We use these dry ice blasting machines in europe in the chemical industry & other service jobs. The machines work very well and are designed to clean effectivally (low consumtion of dry ice and compressed air and good speed in cleaning).

Also look for info under "CO2 bead blasting". The semiconductor industry uses it extensively for cleaning deposits in vacuum tubing. It is clean and essentially residue free.

We have used this process to clean out Boilerclave vessels used in dewaxing investment molds. Works great, only thing to cleanup afterwards, is the blasted off material.

Once you have cleaned it you should coat the product with a nano coating so you don't have to do it again. I have 1 here which works brilliantly.

Dear Susui,,,

Dry Ice Blasting is more effective and effcient compare to other cleaning method.your pump and fitting will be look brand new in less time and cost aswell..

2ndly its non abrasive and enviroment friendly ..no secondory waste at all.
