Title Cleaning of castings in aqueous solutions as an alternative to solvent cleaning
Original title Das Reinigen von Druckguss in wässrigen Lösungen als Alternative zur Reinigung mit Lösemitteln [in German]
Bibliographic information Feb. 1988, Vol.75, No.5, p.110-113. Illus. 3 ref.
Abstract Solutions of inorganic and organic salts in water (10 to 50g/L) and surface-active substances as additives are used in the alternative cleaning process described for die casting. Depending on the material of die castings (e.g. aluminium or zinc) acid, neutral, mild or strong alkaline solutions are employed. Compared with solvent cleaning the process using aqueous solutions can be more widely used and requires extensive waste air cleaning but produces waste water that has to undergo purification.
