If you’re looking for a cleaning method that is non-abrasive, dry ice blasting is the choice for you. Dry ice blasting offers an alternative cleaning method that won’t scratch, damage, or leave a profile on the surface you are cleaning. You can adjust how much blasting dry ice and how much pressure you want to use, making it as gentle or as tough as you need.
Other advantages dry ice blasting has over sandblasting are that it does not create any secondary waste and it is safer for your employees to use because they aren’t breathing in harmful dust sandblasting creates. That’s right; you have little to no cleanup after you clean! As soon as the dry ice hits the surface it is being blasted against, it turns back into a gas or sublimates (as described in our Back to the Basicspost). Therefore, you save time and labor costs by not having to reclaim used blasting media. This makes blasting dry ice a much more convenient, efficient, economical cleaning method.
Plus, one of the best perks to using dry ice blasting is that it can be safely used on a wide variety of applications, including electrical items and machinery. It can also be used to get to those hard-to-reach places without having to disassemble and/or move your equipment thanks to our wide variety of nozzles.
Dry ice blasting could very well offer a safer, easier, and more convenient option for your cleaning needs than sandblasting could. So for your next job, consider Continental Carbonic Products, Inc. as your single source advantage for dry ice blasting!
Blasting Media Comparison
As a general rule, the blaster should use the finest abrasive necessary to attain the required surface preparation characteristics. A fine abrasive will give you more impacts per volume. The more particles in the stream, the more work is accomplished in the same time. When blasting concrete or wood, you don’t need a hard, expensive abrasive, or a coarse particle: crushed glass makes an excellent, inexpensive choice for work on relatively soft surfaces.
However, when preparing iron and steel for a protective coating system, there are additional considerations. Coatings adhere poorly to hard, flat surfaces, so the blaster is required to develop a pattern of indentations that the coating can anchor to, aka the anchor pattern.
The Anchor Pattern
When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile.
In the U.S., the depth profile is measured by mils – thousandths of an inch. In the metric system, the micron(one millionth of a meter) is used.
1 mil = 25.4 microns.
