In industrial fields such as metalworking and parts cleaning, alkaline degreasers are widely used for their excellent degreasing ability. However, in actual operation, excessive foam often becomes a headache. Foam not only overflows the tank, causing waste and environmental pollution, but also covers the surface of workpieces, seriously affecting the degreasing effect, leading to incomplete cleaning and reduced quality of subsequent processes, and may even cause equipment operation safety and workshop cleanliness problems due to foam overflow.
Facing this common market pain point, Chemi Tech, drawing on deep surfactant technology and application experience, has developed a series of highly efficient defoamers specifically for alkaline degreasing systems. Our solution is not a simple addition, but is based on an in-depth understanding of the mechanisms of foam generation. The surfactants in alkaline degreasers easily produce stable foam under mechanical stirring, temperature changes, or the influence of water quality. Through its special modified polyether-siloxane complex, the Chemi Tech defoamer can quickly penetrate and destroy the surface tension of the foam film to achieve rapid defoaming; at the same time, its excellent alkali resistance and high-temperature stability can persistently inhibit the regeneration of foam, ensuring the smoothness of the entire cleaning process.
The specific solution is divided into three steps: the first step is problem diagnosis and model selection, in which our technical engineers analyze your degreaser formula, process temperature, and the causes of foaming, and recommend the best-matching Chemi Tech defoamer model; the second step is on-site trial and addition, in which we guide the customer to test at an addition rate of 0.05% to 0.2% to determine the optimal addition point and dosage; the third step is continuous tracking and optimization to ensure long-term compatibility between the defoamer and the system and achieve a stable foam-inhibiting effect.
For example, an enterprise in East China engaged in precision metal parts processing was long plagued by foam on its high-temperature alkaline spray cleaning line; the foam frequently overflowed, causing shutdowns for cleaning and low efficiency. After adopting the CT-658 model defoamer customized by Chemi Tech, the foam was effectively controlled within minutes of addition, the liquid level in the cleaning tank remained stable, and continuous 8-hour uninterrupted production was achieved; the qualification rate of workpiece degreasing rose significantly, while degreaser loss was reduced by about 15%. The customer highly recognized the improvement in cleaning line efficiency.
Choosing Chemi Tech is not just choosing a product, but choosing a reliable technical partner. We are committed to clearing away foam obstacles for your alkaline degreasing process and improving cleaning quality and overall benefits.
