Coal slag

Coal slag is a dark silicate produced as a byproduct of coal powered plants. As an abrasive, coal slag is generally considered to be one safe option to using non-recyclable industrial blasting media. The different angular shapes of individual coal slag particles make it ideal for efficient removal of rust or paint coatings from steel and other metals in preparation for painting. Coal Slag abrasive is mostly used in both new steel and steel maintenance applications including blasting of storage tanks, water towers, bridges, ships, and oil refinery maintenance.

How does it clean?

Dry ice cleaning uses solid CO, a non-abrasive media that won't damage surfaces or equipment. The super cooled dry ice pellets or particles are accelerated at supersonic speeds and sublimate on impact, resulting in the surface being cleaned, lifting dirt and contaminants off the underlying substrate

How it works...

Instead of abrasive media to grind surfaces (and damage them), Cold Jet uses dry ice (Solid CO2) accelerated at supersonic speeds that sublimate upon impact and lift contaminants from substrates.
