Pickling of metals - Import export

Pickling is chemical etching of metal surfaces using an aggressive, alkaline solution to remove applied metal layers or to get an oxide-free surface (activation of the base metal for further coating). Maximum measurements 4000 x 1000 x 500 mm

Dr. Paul Lohmann® offers Ferric Sulfate as powder in pharma/chem. pure grade and as solution in chem. pure grade. For pharmaceutical applications, it is used for the treatment of iron deficiency anaemia. For industrial applications, it is used for the production of ceramic paints in terracotta shades, as well as for the formulation of metal pickles. Its high purity makes it an ideal REDOX partner in electrochemical processes. CAS 10028-22-5 EINECS 233-072-9 Dr. Paul Lohmann® carries out product and application development in close cooperation with customers. This includes the adaptation of chemical and physical parameters such as bulk density, wettability, particle size, purity or pH-value.

Acid recovery out of pickling acids Salts and acids can be concentrated or separated from solutions by electrodialysis. For this, ions (anions and cations) are transported through the ion exchange membranes by the applied electrical field. Typical examples for the usage of electrodialysis are: Acid recovery at pickling lines Recovery of metals out of electro-plating rinsing water
