In industrial scenarios such as metalworking and mechanical lubrication, emulsified oil is widely used, but the accompanying foam problem often troubles production enterprises. Foam not only causes oil tank overflow, resulting in waste of raw materials and on-site pollution, but also seriously affects cooling effect, lubrication performance and pumping efficiency, and may even cause equipment cavitation, shortening the service life of equipment. How to control foam efficiently and durably has become a technical pain point urgently in need of solution for many factories.
In response to this common demand, Chemi Tech, relying on deep material research and development experience, has launched a series of high-performance defoamers dedicated to emulsified oil. Our solution is not simply an addition, but based on an in-depth analysis of the foam generation mechanism. The surfactants and stable structures in the emulsified oil system are the main causes of persistent foam. Therefore, the core design of our defoamer lies in: first, selecting special modified polysiloxanes and polymers with good compatibility with the system but lower surface tension, which can quickly spread on the foam liquid film; second, the product has excellent high-temperature resistance and shear resistance, remains stable in the circulation system, and is not easily emulsified or dissolved, thereby achieving long-lasting foam suppression.
The specific application steps are clear and simple. First, the customer needs to provide a small amount of sample for compatibility and performance evaluation, and our technical team will conduct tests simulating actual working conditions. After determining the model, it is recommended to add it directly in the emulsified oil production link or at the early stage of foam generation, with a general dosage of 0.1%-0.5% of the total oil amount. During addition, moderate stirring should be maintained to ensure even dispersion. For on-site systems that have already generated severe foam, it can also be directly dripped or flowed into the foam accumulation area to quickly defoam. We emphasize precise dosing to avoid side effects that may be brought by excessive use.
We once served a precision parts manufacturer in East China. When using a certain brand of emulsified cutting fluid, this enterprise continuously generated a large amount of stubborn foam in its high-pressure jet machining center, resulting in blurred machining vision, insufficient effective circulation of coolant, and a decline in the yield of good products. After on-site diagnosis by our technical engineers, we recommended the Chemi Tech CT-360 series defoamer. After the customer added it at a ratio of 0.3% in the circulation tank, the foam significantly subsided within 30 minutes, and in the subsequent continuous two-week monitoring, the foam was always effectively suppressed. The machining environment and product quality were significantly improved, and the customer highly praised the durability of the defoaming.
By choosing Chemi Tech, you are choosing a problem-solving path that is highly targeted and technically reliable. We not only provide products, but also provide analysis based on actual working conditions and continuous technical support, helping customers completely get rid of foam troubles and improve production efficiency and operational stability.
