High Intensity Co2 Blasting is both a non - waste productive and environmentally friendly form of blast cleaning that has been developed to remove existing coating systems, corrosion products and soluble surface salts.
High Intensity Co2 blasting has been derived from traditional dry ice blasting. Advancements in technology have resulted in a more robust process, capable of removing protective coating systems and epoxy passive fire protection.from both steel and concrete substrates.
High Intensity Co2 blasting removes existing coating systems, corrosion products and surface contamination in three ways:
- Kinetic effect of High Density Co2 being propelled at high velocity by compressed air, impacts the surface creating fractures within the coated surface.
- Thermal effect of the High Density Co2 impacting the existing coating system, corrosion products or surface contamination reducing the adhesion to the substrate.
- Expansion of the High Density Co2 sublimating to a gaseous state expanding to 800 times its original size results in lifting the existing coating system, corrosion products or surface contamination from the substrate.
- High intensity Co2 blasting is a controlled method of blast cleaning. The selection of the correct nozzles, rate of blast medium throughput and correct pressure are important elements of this unique application. The result is the complete removal of existing coating systems up to 15mm, corrosion products and surface soluble salts, exposing the original profile of the steel substrate.
