Description
For the protection of metallic materials during the chemical cleaning with hydrofluoric acid and its mixtures with organic acids as well as acid salts of the EDTA (ethylenediamine tetraacetic acid) at temperatures up to 80°C (for aminosulfonic acid only up to max. 60°C).
Benefits
- Contains a combination of specifically acting inhibitors and specific surfactants with high wetting properties. Consequently a uniform distribution in the acid as well as a quick wetting of the surfaces to be cleaned is ensured.
- Is suitable for formic, citric and amidosulfonic acid.
- Does not affect the dissolution of scale as well as rolling and annealing scale.
- Inhibits the corrosion of all metallic materials which are present in the boiler and apparatus construction on the basis of iron and copper.
- The maximum working temperature is 80°C (for aminosulfonic acid only up to max. 60°C).
Dosing, Addition
In general the dosing rate amounts to 2 kg LITHSOLVENT 803 per m³ cleaning solution the concentration of which in general varies from 30 to 100 g/l acid.
For postpicklings with citric acid we recommend a product concentration of 2 kg LITHSOLVENT 803 per m3 cleaning solution.
