Dry Ice Blasting.....
Hi everyone. I am an engineering student. I read something called dry ice blasting while browsing net. Well I donít know why, but I am curious to know about it. I know about traditional labor intensive methods like scrapers, wire brushes, sand blasting and pressure washing. I know dry ice is basically solid form of CO2, but I have no clue about this dry ice blasting.
Can somebody throw some light on this or at least suggest some site where I can find some info on this.

Hey John. Must say buddy, you are quite a curious fellow. You are right dry ice is a solid form of carbon dioxide (Co2). And you must be aware that it is as hard as a plaster and under atmospheric pressure it sublimes at a temperature of -78oC.
Dry ice blasting is a process of cleaning equipments. It is very much in demand nowadays, as it is very environment friendly, safe and cost effective. You would be surprised to know the number of industries it caters to; automotive, power plants, packaging, food and beverage, plastics, aerospace etc.
As this cleaning technology doesnít use any chemical solvents lubricants and water; itís considered ideal for electrical equipments and food and beverage industry.
Dry ice blasting is superior to sand blasting, pressure washing etc. It has lots of benefits. Its not possible to list them out here. Why donít you check out www.react365.com, provides dry ice blasting services and other environmental and industrial services and you will get some information on their site.
Take a look at this dry ice website. They have a few articles explaining the dry ice blasting process. The short form is that dry ice pellets are shot out of a hose at high pressure. As they hit the surface, they blast off the crud. The dry ice turns immediately to a gas, thus leaving no waste to cleanup from the dry ice. It is a very cool process. :-)
