What Is Dry Ice Blasting?

Dry ice blasting is often used to clean CNC machining. It is a method that is used to clean off paint and rust. Dry ice is the solid version of carbon dioxide.

One of the reasons that dry ice blasting is used in local custom machining is because it cleans the surface in a non-destructive way. Dry ice particles and compressed air are used. The dry ice pellets and pressurized air will create an excessive sublimation.

How It Works

A machine and tool company near Raleigh will typically use a consumer pressure washer. The pressure washer will create pressure on the surface by forcing air through the nozzle. There is a reason that dry ice blasting is the preferred method when cleaning CNC machining.

Other methods involve the use of harmful chemicals or too much water. It is safer to use compressed air and dry ice pellets. Additionally, dry ice blasting combines the use of thermodynamics and physics.

The Science of Dry Ice Blasting

The science behind dry ice blasting is simple to understand. The contaminants freeze after the dry ice comes in contact with them. That is why it is effective for removing paint, grease and rust from the surfaces.

The Three Rapid Effects

Stage One

Stage one is also known as the thermal shock. It freezes the contaminants on the surface, which causes them to become brittle.

Stage Two

Stage two is also known as impact shock. It breaks up the contaminants at a high speed.

Stage Three

Stage three is also known as expansion shock. It blows away the contaminants.
