摘要

The inhibitor aqueous corrosu00e7o, composiu00c7u00e7o aqueous acid cleaning corrosu00e7o reuptake inhibitor, and methods of cleaning of metal and produu00c7u00e7o of an inhibitor aqueous corrosu00e7o.Corrosion inhibiting compositions preferably aqueous, stable storage, useful in cleaning solutions acu00eddicas for cleaning of metal surfaces, comprising the reaction products of at least one component of amine colophony, at least one component of ketone net The non flammable, at least one component of carboxylic acid.At least one component of para formaldehyde and water; aqueous acidic cleaners prepared these; and methods for their use. The corrosion inhibiting compositions of the invention are produced by a simple process that reduces the presence of raw materials of toxic and / or flammable, CO products, reagents, and residual chloride ion while providing inhibition of acid in aqueous acidic cleaners.
