Effectively Solving Emulsified Oil Foam Problems: Chemi Tech Defoamer Solution Details

In industrial settings such as metalworking and mechanical lubrication, emulsified oils are widely used, but the accompanying foam problem often plagues production enterprises. Foam not only causes overflow from oil sumps, resulting in raw material waste and site contamination, but also severely affects cooling performance, lubrication efficiency, and pump performance, and may even lead to equipment cavitation, shortening service life. How to control foam efficiently and persistently has become a pressing technical challenge for many factories.

Addressing this widespread need, Chemi Tech, leveraging deep material R&D expertise, has launched a series of high-performance defoamers specifically for emulsified oils. Our solution is not merely about addition but is based on in-depth analysis of foam generation mechanisms. The surfactants and stable structures within the emulsified oil system are the main reasons for persistent foam. Therefore, the core design of our defoamer focuses on: First, selecting specially modified polysiloxanes and polymers with good compatibility with the system but lower surface tension, enabling rapid spreading on the foam film. Second, the product exhibits excellent resistance to high temperatures and shear, maintaining stability in circulating systems,不易被乳化或溶解, thereby achieving long-lasting foam suppression.

The specific application steps are clear and straightforward. First, customers need to provide small samples for compatibility and efficacy evaluation. Our technical team will simulate actual working conditions for testing. After determining the model, it is recommended to add the defoamer directly during the emulsified oil production stage or at the initial stage of foam generation, typically at a dosage of 0.1% to 0.5% of the total oil volume. Moderate stirring is required during addition to ensure uniform dispersion. For on-site systems already experiencing severe foam, direct drop-wise or flow addition to the foam accumulation area can achieve rapid defoaming. We emphasize precise dosing to avoid potential side effects from overuse.

We once served a precision component manufacturer in East China. The enterprise encountered persistent, massive foam in its high-pressure spray machining centers when using a certain brand of emulsifiable cutting fluid, leading to obscured machining vision, insufficient effective coolant circulation, and decreased product yield. After on-site diagnosis by our technical engineer, Chemi Tech's CT-360 series defoamer was recommended. After the customer added it at a 0.3% ratio to the circulation tank, foam significantly subsided within 30 minutes. During subsequent continuous two-week monitoring, foam remained effectively suppressed. The machining environment and product quality saw marked improvement, and the customer highly praised the persistence of the defoaming effect.

Choosing Chemi Tech means opting for a targeted, technologically reliable problem-solving path. We provide not only products but also analysis based on actual working conditions and continuous technical support, helping customers completely overcome foam troubles and enhance production efficiency and operational stability.
