Chemi Tech Oil-Based Defoamer Successfully Resolves Foam Issue in Precision Electronic Component Cleaning Process

Recently, the KM-520 series oil-based defoamer, developed by Chemi Tech, has achieved notable application results at a manufacturer specializing in precision electronic components, successfully assisting in resolving a persistent foam control challenge during the component cleaning process.

The manufacturer's cleaning procedure employs a specific oil-based cleaning system designed to thoroughly remove fine particles and grease residues from component surfaces. However, during high-speed spraying and circulation filtration, the cleaning solution was prone to generating substantial, stubborn foam. This foam not only overflowed from tanks, creating slippery working conditions and material waste but, more critically, adhered to component surfaces, causing shadowing that left some areas inadequately cleaned. This directly impacted the quality consistency of subsequent coating or assembly steps, posing a bottleneck to improving product yield rates.

Upon receiving the feedback, the Chemi Tech technical team conducted an in-depth on-site investigation. They identified that the high-temperature cleaning system contained various surfactant components, placing stringent demands on the defoamer's compatibility and persistence. Based on this analysis, the team recommended the KM-520 oil-based defoamer, specifically formulated for oil-based systems. This product utilizes a specially modified polysiloxane compound that maintains structural stability under high shear and temperature conditions. It rapidly spreads and ruptures foam films while exhibiting excellent compatibility with the system, preventing oil spots or secondary contamination on component surfaces.

Following rigorous online testing, with the addition of an appropriate amount of KM-520 defoamer, foam within the cleaning tank was instantly and persistently suppressed, with foam height reduced by over 95% and overflow completely eliminated. Components cleaned post-application were tested and found to meet all surface cleanliness standards without any residues that could interfere with subsequent processing. The cleaning line's efficiency improved, with downtime for foam-related cleanouts significantly reduced, leading to smoother overall operation. The manufacturer's representative stated that resolving the foam issue provided strong support for process stability and product reliability.

This successful application reaffirms Chemi Tech's R&D capabilities in providing targeted defoaming solutions. The KM-520 series oil-based defoamer, with its efficient and persistent foam control performance, offers a reliable choice for foam management in similar oil-based systems. Chemi Tech remains committed to understanding the process needs across various manufacturing sectors, leveraging innovative chemical additive solutions to help customers enhance production efficiency and product quality.
