In the field of metalworking, fully synthetic cutting fluids, with their excellent cooling, lubrication and rust-prevention performance, have become the first choice in many precision machining scenarios. However, their inherent high cleanliness and formulation characteristics make them highly prone to generating a large amount of stubborn foam under working conditions such as high-speed circulation, high-pressure spraying or soft water. Such foam not only overflows the tank, causing waste and a slippery floor, but also severely affects the cooling effect of the cutting fluid, reduces its lubricating performance, and may even lead to decreased machining accuracy, increased tool wear and idling of the equipment's pumping system, becoming a common pain point that troubles production engineers.
Facing this challenge, simple physical foam removal or the addition of ordinary additives often has limited effect or brings side effects. Based on in-depth research on fully synthetic cutting fluid systems, Chemi Tech has developed a series of dedicated defoamer products. Our solution does not simply and crudely suppress the foam but, through a unique molecular design, achieves a balance between rapid foam breaking and lasting foam suppression. The product has excellent compatibility and will not affect the cutting fluid's original transparency, stability or various performance indicators.
The specific application steps are clear and simple: First, analyze the specific causes of the foam (such as water quality, concentration and circulation pressure). Second, under stirring, slowly add the recommended dosage of Chemi Tech defoamer (usually 0.1%-0.5%) into the circulation system. Finally, keep the system running so that it disperses evenly. For newly prepared fluid, it can be added directly during the dilution stage. Our technical team can provide on-site or remote guidance to ensure the best results.
We once served an enterprise focusing on the manufacture of aluminum alloy parts. It used a fully synthetic cutting fluid in its high-pressure cleaning process, where foam overflowed severely, forcing frequent shutdowns for cleaning. After adopting our customized defoaming scheme, the foam was significantly controlled on the very day of addition; after a week of continuous operation, the foam volume stabilized at a very low level, the workshop environment was greatly improved, the downtime caused by foam dropped to zero, and the cleaning quality of the machined surfaces was also improved. The customer was satisfied with the durability of the treatment effect.
Choosing Chemi Tech means you gain not only a high-efficiency product but also a systematic solution to the foam problem. We are committed to helping customers optimize the performance of their machining fluids, ensure smooth production and improve overall benefits.
