A new, emotional polygonal additive to inhibit the corrosion of North Atlantic anhydrides and their use methods

摘要

There, polyurethane additive is a kind of multi-element phosphate mat, which is extracted from polyurethane phosphate mat. In addition, a method is introduced to suppress the corrosion of Naxin acid on the metal surface of the processing device which processes the current containing Naxin acid in the reactor. The method includes: (a) heating the current containing Naxin acid to make part of it evaporate; (b) allow the steam in the stream to rise in the distillation column;(c) condense part of the mist flowing through the distillation column into a kind of distillation liquid; (d) distill enough nafcinic acid corrosion inhibitors to achieve the purpose of inhibiting nafcinic acid corrosion; It is allowed that the distilled agent containing sodium acid corrosion additive forms a protective layer on the substance and the metal surface completely contacting the distillation unit to prevent corrosion.
