Using Dry Ice Blasting to Remove Product Residues
Dry ice blasting is a type of abrasive blasting that uses dry ice to clean a surface. This method is a non-destructive way of cleaning stubborn product residues that have adhered to any types of surface. This method uses dry ice, which is made from frozen carbon dioxide. One application of dry ice blasting is to remove epoxy or glue after installing wall paper in a room. Other applications include removal of graffiti, soot and stains on concrete and wooden surfaces. However, the substrate that can be cleaned by dry ice blasting is not limited to wood or concrete, but includes steel, plastic and even alloys can be cleaned through dry ice. Here are the steps on how to remove product residues using dry ice blasting.
For This DIY Project, You Need the following Materials:
- Insulated gloves
- Ear plugs
- Dry ice
- Dry ice blasting equipment
- Portable exhaust fan
Step 1 - Wear Your Personal Protective Equipment
Before starting the process, it is important that you wear your personal protective equipment, such as the goggles, insulated gloves and ear plugs. The process of dry ice blasting is noisy, thus you need to protect your ears. Moreover, the dry ice temperature is minus 109 degrees Fahrenheit, which makes it much colder than the conventional ice made from water.
Step 2 - Load the Dry Ice in The Dry Ice Blasting Equipment
Once you are ready, load the dry ice carefully in the dry ice blasting equipment. Turn on the equipment, until the desired pressure is reached. Before blasting the surface, make sure that you point the gun between 45 and 90degrees. It is important that you do not point the dry ice gun at another individual, to prevent any accidents.
Step 3 - Turn On The Portable Exhaust Fan
While you are blasting away the product residue using the dry ice gun, make sure that you turn on the portable exhaust fan while working. A portable exhaust fan is necessary to suck out the excess carbon dioxide, which may build up in the area or room where you are working. Carbon dioxide is 40 percent heavier than air, thus it is important to place the exhaust fan near the ground level.
Step 4 - Remove the Dry Ice on the Surface to Prevent the Surface from Cracking
While blasting dry ice on the surface, make sure that you remove pieces of dry ice that adhere to the surface, since this could result in the disintegration and cracking of the surface. To remove pieces of dry ice stuck on the surface, you can use a spatula.
Step 5 - Clean Up the Equipment after Use
Once the product residue has been removed, make sure that you unwrap or expose the dry ice in a well-ventilated area. Dry ice will immediately change from its solid to gaseous state under normal room temperature. Store the dry ice blasting equipment in a well-ventilated storage area.
