In alkaline cleaning processes for fields like metal processing and component manufacturing, excessive foam is a common and troublesome issue. Overabundant foam not only reduces the effective volume of the cleaning tank, leading to decreased utilization of the cleaning agent, but also severely impacts the contact effectiveness of spray or immersion cleaning, resulting in incomplete cleaning. Furthermore, foam overflow can contaminate the working environment, increase subsequent handling costs, and even affect the continuous stable operation of the production line.
Addressing this pain point, the Chemi Tech R&D team has deeply analyzed the foam generation mechanism in alkaline cleaning systems. We found that under complex conditions of high temperature, high alkalinity, and the presence of surfactants, traditional defoamers often face problems such as rapid dissolution, quick decay of foam-breaking efficiency, or poor compatibility with the system, unable to provide durable and stable foam control.
To tackle this, Chemi Tech has launched a high-performance defoamer series specifically designed for alkaline cleaning environments. The core of our solution lies in: First, selecting specially structured polyethers and modified silicone materials as the base to ensure the defoamer maintains chemical stability under strong alkaline conditions and is not easily decomposed. Second, by optimizing molecular weight distribution and hydrophilic-lipophilic balance, the defoamer can quickly penetrate and disrupt the foam film, while maintaining high efficiency throughout the entire cleaning cycle. Finally, the products undergo rigorous compatibility testing and exhibit good compatibility with various common alkaline cleaning agents, without affecting the core functions such as decontamination and degreasing of the main cleaning agent.
The specific application steps are clear and straightforward: Step one, select the Chemi Tech recommended defoamer model based on the total alkalinity, temperature, and severity of foam in the cleaning tank solution. Step two, simultaneously with the addition of the cleaning agent or at the initial stage of foam generation, directly add the defoamer into the tank solution at the suggested dosage (typically 0.1%-0.3%). Step three, lightly stir or rely on the circulation system to distribute it evenly. The defoamer will rapidly take effect, suppressing new foam generation and eliminating existing foam. During subsequent production, only periodic supplementation of a small amount is needed to maintain a long-lasting foam-free state.
We once assisted a company engaged in precision component processing to solve the foam overflow problem in its alkaline degreasing line. This production line used high-temperature alkaline cleaning solution, where foam frequently overflowed the tank, causing the automatic spray system efficiency to drop by approximately 30% and requiring frequent stoppages for cleanup. After adopting Chemi Tech's specific defoamer model, foam was significantly controlled within ten minutes of addition, the tank's effective working volume was restored, and spray coverage uniformity improved. The production line achieved stable operation for 8 consecutive hours, the foam overflow issue was essentially eliminated, and the consumption of cleaning agent also decreased by about 15% due to improved efficiency. The customer highly appreciated the persistence of the defoaming effect and the zero negative impact on cleaning quality.
