Title:
【発明の名称】表面から中鎖カルボン酸金属塩の除去
Document Type and Number:
Japanese Patent JP2002526559
Kind Code:
A
Abstract:
Problems of extensive foaming and/or of sticky deposits on process equipment that often arise when metal soaps from metal articles that have been given a metal soap containing surface to aid in drawing are removed with aqueous alkaline cleaners can be avoided by including in the cleaners used anions such as calcium and magnesium that are capable of precipitating the anions of the metal soaps. The cleaners advantageously also contain chelants, a mixture of nonionic and anionic surfactants, and phosphorus containing anions. Anions from the metal soaps are eventually precipitated from the cleaners used as non-sticky sludge that can be easily separated from the cleaners.
