Wintersun HCL Acid Inhibitor

Applications

Wintersun HCL Acid Inhibitor represents a new concept in Hydrochloric acid inhibition. In contrast to conventional acid inhibitors that are often film-forming chemicals, Wintersun HCL Acid Inhibitor protects metals through adsorption to the specific corrosion sites. The advantages to this approach are numerous. First, it is difficult to over-inhibit the pickling bath by accidentally adding too much Wintersun HCL Acid Inhibitor since metal protection does not occur until after the oxide layers have been removed. Furthermore, the chemical nature of Wintersun HCL Acid Inhibitor facilitates acid attack on the oxide scale, particularly where scale-breaking has occurred. This has the effect of increasing the speed at which HCl is carried to the metal surface, maximizing the rate of scale removal and ultimately leading to faster processing speeds. Finally, in contrast to film-forming inhibitors, the corrosion protection afforded by site-specific inhibitors results in a cleaner metal surface because a more uniform acid attack is achieved. Wintersun HCL Acid Inhibitor protects at specific corrosion sites and does not form a continuous film, therefore lower concentrations may be used without fear of over-pickling. Wintersun HCL Acid Inhibitor provides excellent protection and shows great stability in high iron HCl pickling systems. It reduces or eliminates hydrogen embrittlement. Due to differences in picking lines, grades of steel, water sources, etc., consult your Crown representative for proper feed rates. Wintersun HCL Acid Inhibitor can be added to the raw acid or to the pickling solution. It is effective at temperatures to 210° F, and will not oil out or break down. Wintersun HCL Acid Inhibitor is very effective for inhibiting hydrochloric acid used in acidizing wells (oil, gas or water) located in limestone formations. It protects the metal surfaces of the well piping, pumps, and acid-transportation equipment. Wintersun HCL Acid Inhibitor’s other uses include inhibition of HCl acid used in cleaning industrial boilers, heat exchangers, and condensers, as well as inhibition of HCl acid that is used in liquid products such as copper cleaners and toilet bowl cleaners.
