Consumption & Production

The tightly screened sizing of the CHROMA ABRASSIVES ensures a maximum number of grains unit weight. Blasting speed is a result of the number of impacts on the surface. CHROMA ABRASSIVES 30/60 Mesh contains approx. 11.00 Million impacting grains per kg of abrasive compared to a coarser slag or sand of a 20 Mesh with only 1.00 Million grains per kg. Depending on the application, this results in up to twice the cleaning rate of CHROMA ABRASSIVES with 1/3 of the abrasives used compared to the other conventional abrasive.

Dust Levels

CHROMA ABRASSIVES GRAINS are among the hardest and toughest natural minerals known to man.The unique Geological history of the grains has ensured that only toughest have survived.

CHROMA ABRASSIVES therefore has a very low friability. The breakdown rate on impact is low enough to allow multiple recycles .Because of the high density and specific high gravity, rebounding CHROMA ABRASSIVES grains Fall rapidly to the ground close to the blasted surface.

CHROMA ABRASSIVES therefore produces virtually NO DUST which provides for excellent operator visibility, Minimum contamination of adjoining work areas and a clean healthy environment.

In comparison, Slag is quenched from its molten state with cold water (in some cases seawater) and crushed, giving each particle shatters into minute particles and become airborne due to their small size and low specific gravity, Resulting in the generation of high dust levels.

Likewise silica sand is very brittle with most grains disintegrating on impact causing excessive levels of siliceous dust Which is a major health hazard and serious.

Surface Quality

CHROMA ABRASSIVES grains properly clean and scour deep into cavities and rust pockets of the steel surface easily achieving an SA3 quality finishing, free of embodiments and free of excessive peaks. Because of the tight grain size distribution, a surface profile of 50-75 microns with a very large number of peaks per unit area is achieved uniformly All over the blasted surface .An extremely low chloride content and no sulphur contamination ensures the blasted surface provides an ideal base for any subsequent coating application.

Steel surface blasted with coarser and angular slags are left with slag particle impregnated into the steel surface. These Inclusions,up to 500 particle per square inch be the cause of premature coating failure. Coarser and more angular slags Produce excessive peaks and throughs and often fail to clean deep into cavities, leaving behind rust pockets that become corrosive cells.
Environmental Health & Safety

CHROMA ABRASSIVES are totally natural products, free of heavy metals or any toxic components. Copper slag/nicle slag etc are waste products of the metals refining industry and frequently containds unacceptable levels of toxic heavy metals such as lead, copper, zinc, arsenic cadmium etc. Silica sand has been banned as blasting abrasive in Most countries around the worldas it is fine dust can cause the deadly disease Slilicosis.
