ALIT Technologies expands its surface treatment solutions by introducing Drizzling, an innovative non-chromic conversion coating system designed for precise, uniform application on metal surfaces. Developed to meet growing environmental and performance demands, Drizzling offers superior corrosion resistance while eliminating the use of hexavalent chromium.
This innovative dosing and application system for the non-chromic conversion coating significantly enhances the pre-treatment process for metals, ensuring longer bath operational performance with consistent quality and cost savings.
HOW IT WORKS
Drizzling is an entirely automated dosing and application system that precisely mixes demineralized water drawn from a supply tank with the exact amount of passivating chemical. This ensures a solution that is always fresh, ready to be dispensed directly onto the surface of the artifacts.
Thanks to special nebulization nozzles combined with compressed air, Drizzling generates a fine light mist, which homogeneously covers the treated pieces with the passivating solution. The system is effective on horizontal and vertical coating lines, including those treating aluminum profiles up to 23 feet.
The Drizzling system stands out for its extremely compact structure and ease of installation, features that make it easy to integrate into any production line. Its main strength is the ability to apply a passivating solution to the products to treat; an always fresh solution, free of contaminants and prepared at the moment, thus offering an additional guarantee on the quality of the treatment and the final performance of the product.
Furthermore, Drizzling is perfectly compatible with chromium-free chemicals, such as ALFICOAT 748/3 by Alufinish GmbH, a formulation based on polymers and titanium that ensures excellent results in terms of both corrosion resistance and paint adhesion, further improving the overall effectiveness of the surface treatment cycle.
Key Advantages of the Drizzling System
The Drizzling system offers significant operational and environmental benefits:
- Eliminates the need for a dedicated recirculation tank: The low volume of passivation solution applied and the elimination of collection and re-spraying streamline the process and minimize solution handling
- Solves disposal issues related to solution aging: Waste from aged solutions is eliminated by preparing and applying a fresh mixture for each cycle.
- Ensures a contaminant-free solution: Freshly prepared solution guarantees reliable and high-quality surface treatment outcomes,
- Facilitates easy conversion to chrome-free systems: Existing chromate conversion coating lines can be upgraded to chrome-free operation with minimal structural changes.
- Requires minimal footprint: Installations can be as compact as approximately 12 inches long, saving valuable floor space.
