Project Description
Cleaning of Sheet Metals Coils
General
The cleaning of metal strips places particularly high demands on the quality of the products used. Only a completely cleaned surface guarantees problem-free coating or finishing in subsequent processes. Therefore, the typical impurities such as fats, oils, organic additives, metal dusts, oxides, and metal salts must be completely removed. We offer products for the cleaning and degreasing of all common materials and for every process type.
Materials
Our products have been continuously used for over 20 years in the cleaning of metal strips of steel, stainless steel, galvanized steel, aluminum, copper and brass. The experience gained in this process is part of the development of new products.
Processes
A wide range of methods is used in the cleaning of metal strips. Our products are optimized for spraying, dipping, brushing as well as for electrolytic and ultrasonic cleaning. For each process, there are a number of products that are optimally adapted to the respective operating parameters.
Determination of iron in aqueous solutions
Products
With the offered products we take into account all the requirements for the surface finish after cleaning. Furthermore, by adapting to the respective procedure we guarantee a uniform result and a stable process sequence.
- Acidic and alkaline products for a specified metal removal rate as well as neutral cleaners for a pickling-free cleaning.
- Products for low-foaming cleaning in all temperature ranges.
- Adaptation to the respective waste water and disposal technology.
- Complementary products for highly foaming saponification byproducts (defoamers) and heavy soiling (cleaning additives).
- Silica-containing products for hood annealing.
For a reliable before-and-after comparison, a precise determination of the surface cleanliness is necessary. Several quantitative methods are available for this purpose. With a thermochemical carbon analysis, organic components (oils, fats and metal soaps) are determined to 0.1 mg / m2. Inorganic components (metal dusts, silicates or inorganic salts) can be determined photometrically or by X-ray fluorescence.
Laboratory scale simulation of a cleaning process
Cleaning Process
After the laboratory phase, we perform the cleaning process in a pilot plant. Larger band sections are cleaned and the results are also evaluated.

Product Development
The elaboration of methods for concentration determination completes product development. The methods usually comprise the determination of acid or alkalinity, salt and surfactant content. In addition, we support our customers with questions of bath care with simulations of ultrafiltration and investigations on the foaming of roller oils. The introduction of a new product is accompanied during the operational test phase by employees from the laboratory and the technical field service.
