Le degreasing in metallurgy is a critical step that presents numerous challenges for industrial operators. Whether it's removing cutting oils or protective greases, the performance of this step determines the quality of subsequent surface treatments (welding, painting, assembly). Indeed, inadequate surface preparation can lead to defects in subsequent processes, resulting in additional costs and production delays.
However, conventional degreasing methods (solvent baths, chemical cleaners) struggle to meet modern requirements. The main drawbacks of these processes are well-documented. For example, solvent baths require frequent monitoring to maintain their effectiveness, which can lead to production interruptions.
- Operating costs:high energy consumption to heat baths, purchase of chemical products, and costly waste management, including volatile organic compounds (VOCs).
- Risks and safety: operator exposure to harmful substances and handling of dangerous materials, subject to increasingly strict regulations (e.g., REACH*).
- Environmental impact: production of pollutant effluents requiring heavy and regulated treatment.
- Abrasiveness and damage: certain methods can damage delicate surfaces, seals, or nearby electrical components—a major risk in precision metallurgy.
- Downtime: the soaking, washing, and mandatory drying process immobilizes parts and significantly slows production lines.
*: REACH is the acronym for Registration, Evaluation, Authorisation and Restriction of CHhemicals (major European regulation on chemical products). In French: Registration, Evaluation, Authorization and Restriction of Chemical products. This highlights the importance of regulatory compliance in choosing degreasing methods.
Degreasing challenges in metallurgy: toward more effective solutions
Faced with these degreasing challenges in metallurgy, the industry is actively seeking alternatives that are both effective, fast, and environmentally friendly. The goal is to clean thoroughly, without water, without solvents, and without drying time. Companies are investing in research to develop innovative methods that meet market needs while minimizing their environmental impact.
Innovative technologies, such as dry ice blasting, are specifically designed to address these issues. This process uses dry ice to eliminate contaminants without resorting to chemical products, thus offering a safer and more environmentally friendly alternative.
