In the production processes of fine chemicals, textile auxiliaries, metal cleaning and other fields, foam generated in strong alkaline systems is often a troublesome problem. Such foam not only reduces the effective volume of reactors and affects heat and mass transfer efficiency, but may also lead to material overflow and uneven product quality, and may even cause production safety risks. Traditional defoamers tend to lose activity and decompose under the harsh conditions of strong corrosiveness and high pH, resulting in short-lived defoaming effects and the need for frequent addition, which instead increases costs and process complexity.
To address this core pain point, the Chemi Tech R&D team has launched a series of defoamers designed specifically for strong alkaline environments. This series uses modified polyethers and silicone substances with special structures in a scientific formulation, and its molecular structure remains highly stable under high alkalinity, making it resistant to saponification or demulsification. It can not only quickly penetrate the foam film wall and cause the foam to rupture instantly, but also remain dispersed in the working liquid for a long time to continuously suppress the generation of new foam, achieving a perfect combination of rapid defoaming and long-lasting foam suppression.
Our solution is clear and easy to implement: first, we analyze foam samples and working conditions on site to determine the causes of the foam and the specific parameters of the system; second, based on the analysis results, we select the most suitable model from the Chemi Tech strong alkaline defoamer series and provide samples for application testing; finally, based on the test results, we determine the optimal dosing point and dosage, usually 0.05%-0.3% of the total material, to achieve a significant and lasting defoaming effect.
For example, a company engaged in the production of new building material auxiliaries experienced severe foam overflow in a synthesis reaction involving potassium hydroxide solution, requiring a mid-process shutdown for every batch. After adopting the strong alkaline defoamer specifically recommended by Chemi Tech and adding a tiny amount of the product once at the beginning of the reaction, the foam was fully controlled throughout the entire reaction cycle, equipment utilization increased by about 20%, and batch-to-batch product stability was also greatly improved.
Choosing Chemi Tech means choosing not just a product, but a systematic solution for strong alkaline foam. We are committed to using professional technology and reliable products to help customers clear production obstacles and achieve cost reduction, efficiency improvement and process upgrading.
