Industrial Rust Removal Acids and Water-Based Solutions Explained
WebMar 10, 2024 · Acid-free, water-based industrial rust removers utilize a slightly different chemical process to react specifically with rust and remove it from the metal. While acids break down and dissolve rust, acid-free, water-based rust removers draw the rust away or lift it from the metal. This process is generally accomplished through chelation. WebThe most frequently used formulations are based on phosphoric acid which cause the rust to be converted to firmly adhering iron phosphate layers. In addition, formulations based on naturally occurring polyphenols (tannin) are also used; due to a reaction with the iron ions, these lead to virtually insoluble iron complex compounds. WebPickling is a method of preparing metal surfaces by chemical reaction, electrolysis, or both. In pickling, rust and scales are removed by chemical reactions with mineral acids and with certain alkaline materials. Various acids used in commercial pickling include sulfuric, hydrochloric or muriatic, nitric, hydrofluoric, and phosphoric acid, and ... incident box orange
