In links such as metal treatment and industrial equipment cleaning, acid cleaners are widely used for their powerful descaling and oxide-removal capabilities. However, in actual operation, factors such as intense chemical reactions, the addition of surfactants and mechanical stirring very easily cause the cleaning liquid to produce a large amount of stubborn foam. This foam not only overflows the tank, causing waste of raw materials and on-site contamination, but also seriously affects the contact effect of cleaning, leading to incomplete cleaning, difficulty in subsequent rinsing, and water marks or spots after drying, ultimately affecting the appearance and quality of the product, and may even cause operational safety hazards because the foam blocks the line of sight.
The market generally faces the problem of foam control: many general-purpose defoamers easily decompose and fail in strongly acidic and high-temperature environments, with slow defoaming speed and poor persistence, and cannot meet the needs of continuous production; some products may even introduce impurities after addition, affecting the original performance of the cleaning agent or causing secondary contamination of the cleaned objects.
In response to these core pain points, the Chemi Tech R&D team has launched a series of high-performance defoamers designed specifically for acidic cleaning systems. This solution is based on special modified silicone polyether and composite technology, ensuring that at a low dosage the defoamer can maintain excellent chemical stability and dispersibility in a strongly acidic medium. Its mechanism of action is to rapidly reduce the local surface tension of the liquid film on the foam surface, causing the liquid film to rupture unevenly, thereby achieving the dual effect of instantaneous defoaming and lasting foam suppression.
The specific application steps are clear and simple: first, according to the volume of the cleaning tank liquid, the severity of the foam and the specific process conditions (such as temperature and acid concentration), it is recommended to start a small-scale test with a dosage ratio of 0.1% to 0.5%. Second, under stirring, slowly add the defoamer to the cleaning working liquid so that it is evenly dispersed. For foam generated during continuous production, it can also be continuously replenished by dripping or a metering pump to maintain long-lasting foam suppression. Finally, it is recommended that users verify under actual production conditions, and our technical team can provide on-site adaptation guidance.
We once served a precision parts processing enterprise located in East China. When this enterprise used a certain brand of acidic degreasing cleaner, the foam overflow problem was serious, requiring a shutdown for cleaning every two hours, with a capacity loss of more than 30%. After adopting Chemi Tech's dedicated defoamer for acid cleaning, added at a ratio of 0.3%, the foam was significantly controlled within a few minutes after addition, achieving continuous 8-hour production without foam overflow; the surface cleanliness of the cleaned workpieces was significantly improved, the water mark residue problem was basically solved, and the overall cleaning efficiency increased by about 25%. The customer gave high praise for the cleaning quality and production continuity.
Choosing Chemi Tech means choosing not only a product, but also a reliable solution to foam problems. Our technical team is committed to using professional technology and products to help customers improve process efficiency and ensure stable production and excellent quality.
