How to Solve Foaming Issues in Alkaline Degreasing? Chemi Tech Defoamers Offer Efficient Solutions

In industrial sectors such as metal processing and component cleaning, alkaline degreasers are widely used for their excellent grease removal capabilities. However, excessive foam often becomes a troublesome issue in practice. Foam not only overflows, causing waste and environmental concerns, but also shields workpiece surfaces, severely impairing degreasing effectiveness. This leads to incomplete cleaning, reduced quality in subsequent processes, and may even trigger equipment safety and workshop hygiene issues due to overflow.

Facing this widespread market pain point, Chemi Tech leverages profound surfactant technology and application experience to develop a series of high-efficiency defoamers specifically designed for alkaline degreasing systems. Our solution is not merely about addition, but is based on an in-depth understanding of foam generation mechanisms. Surfactants in alkaline degreasers easily produce stable foam under mechanical agitation, temperature variations, or water quality influences. Chemi Tech defoamers, through their specially modified polyether siloxane compounds, can rapidly penetrate and disrupt the surface tension of foam films, achieving quick defoaming. Meanwhile, their excellent alkali resistance and high-temperature stability ensure persistent suppression of foam reformation, guaranteeing a smooth cleaning process.

The specific solution involves three steps: First, problem diagnosis and selection. Our technical engineers analyze your degreaser formulation, process temperature, and foaming causes to recommend the most suitable Chemi Tech defoamer model. Second, on-site trial and addition. We guide clients to conduct tests with an addition ratio of 0.05% to 0.2%, determining the optimal injection point and dosage. Third, continuous follow-up and optimization to ensure long-term compatibility of the defoamer with the system and achieve stable foam inhibition.

For instance, a precision metal parts processing company in East China previously struggled with severe foam in its high-temperature alkaline spray cleaning line. Frequent foam overflow led to downtime for cleanup and low efficiency. After adopting the customized CT-658 defoamer from Chemi Tech, foam was effectively controlled within minutes of addition. The cleaning tank liquid level remained stable, enabling continuous 8-hour uninterrupted production. The qualified rate of workpiece degreasing significantly improved, while degreaser consumption was reduced by approximately 15%. The customer expressed high satisfaction with the enhanced cleaning line efficiency.

Choosing Chemi Tech means not only selecting a product but also partnering with a reliable technical ally. We are committed to clearing foam obstacles in your alkaline degreasing process, enhancing cleaning quality and overall operational benefits.
