How to Reduce Operational Costs and get a Superior Maintenance Cleaning Result
|
|
When you need to remove contaminants, grime, production by-product, old paint etc from a surface on a large scale, there are many solutions – and many problems getting a cost effective and superior result.
 |
Are you looking for a maintenance cleaning process for your plant and equipment that will cut downtime and free up maintenance staff?
|
|
Do you need to clean high value equipment – casings, machined surfaces, production moulds, subframes, radiator fins – and concerned about potential damage?
|
|
Have you contaminated paint to remove and want to avoid the disposal of large quantities of waste cleaning media? |
|
Have you got a cleaning problem where you can’t use wet of abrasive cleaning methods? |
|
Are you under pressure to reduce the use of solvents and other toxic cleaning materials? |
Dry ice blasting is an advanced cleaning system with a wide range of uses.
At Gilsen we are expert in the process, and we have an engineering background to ensure valuable equipment is cleaned effectively and without risk. We will tell you when dry ice blasting is not the best solution and will guarantee results – if we don’t deliver on what we promise you, we will give you your money back – no questions asked.
How It Works
Dry ice blasting is similar in principle to sand blasting using high-density carbon dioxide (dry ice) pellets, propelled onto a surface using compressed air.
It removes contaminants quickly, without leaving cleaning media (e.g. water, sand, chemicals), without any abrasive damage to surfaces, and is dry and safe around electrical equipment.
The cleaning process occurs through the combination of three different effects:
Kinetic Energy is transferred by the accelerated dry ice pellet as it hits the surface during the dry ice cleaning process. The dry ice pellet sublimates upon impact and is softer compared to other cleaning media such as sand, grit, or beads.
Thermal-Shock Effect occurs when cold dry ice pellets (-79 degrees C) strike a much warmer, contaminated surface. The extremely cold temperature of the dry ice causes the bond to weaken between the surface being cleaned and dirt and residue on it.
Thermal-Kinetic Effect combines the impact of sublimation and the rapid heat transfer discussed above. When the dry ice pellet hits the contaminated surface, the vapour expands up to 800 times the volume of the pellet, and so fast that a micro-explosion occurs, taking off dirt and grime in the dry ice cleaning process.
Dry ice blasting in the New Zealand media
New Zealand Engineering News has published an article on dry ice blasting in their September 2012 issue, or you can access the digital version at http://www.engineeringnews.co.nz/node/599
DEMM Engineering & Manufacturing Magazine has a piece on dry ice blasting in their November issue (p34). The issue can be read online also http://issuu.com/adrenalinpublishing/docs/demm_november_2012_geon/1
