ADVANTAGES OF BAKING SODA BLASTING Cleaning & De-Coating in One Step Standard abrasive blasting is a dirty process, often loading and even embedding the surface with contaminants (grease, oil, tar & abrasive particles) in the process of removing the coating. Recycled abrasives compound this problem by loading increasing amounts of contaminants into the substrate. Natrium 260 soda blast media effectively de-coats and cleans the substrate in one step; producing a level of cleanliness not seen with most processes. The media is not reusable thus eliminating the issue of blasting with reused media. Coating adhesion relies heavily on surface cleanliness and a surface profile has been used to offset this lack of cleanliness. Unique Cutting Action Natrium 260 soda blast media offers the unique properties of sodium bicarbonate, the primary ingredient. The softness (Mohs hardness scale of 2.4) and friable nature of this crystal produces a unique cutting action with little or no effect on most substrates. For example, thick coatings can be removed from glass without any etching effect. With proper care, delicate substrates can be cleaned without damage. No Pre-Cleaning Required For projects where the coating is covered with grease, carbon, salt or other contaminates, the more traditional methods require the coating to be fully cleaned before blasting. This is required so that the contaminants on the surface of the coating are not driven through the coating and into the surface of the substrate, causing future coating failure. No Need to Re-Profile Steel Natrium 260 soda blast media will not profile steel, when an operator removes a coating from a metal surface; he or she exposes the existing anchor pattern under the coating. Unless corrosion has occurred, there is no need to re-profile the surface. Reduced Solid Waste Natrium 260 Soda blast media can be dissolved in fresh water. By dissolving the media and filtering out the contaminates, the solution can generally be discharged to POTW treatment systems or open waterways, with proper discharge permits. Waste volume is generally reduced to less than 5% of the original waste volume. With increasing landfill costs and liabilities, this advantage becomes more important every day. Natural Rust Inhibitor As long as the baking soda residue is on a ferrous metal surface, rust will not form. For rust to form , free moisture and an acidic condition must exist. In most cases, free moisture combines with carbon dioxide in the atmosphere to form carbonic acid. This acid releases a free metal (ferrous) ion, which combines with oxygen (oxidizes) to form rust. Baking soda buffers the acids, prevents the release of free metal ions and prevents rust.
