What is a metalworking fluid defoamer?
A metalworking fluid defoamer is a special additive used to inhibit foam generation during metalworking processes. It is commonly added to metalworking fluids such as cutting oils, coolants, and grinding fluids to improve the surface tension of the fluid, eliminate foaming, and improve the fluid's cooling and lubricating properties. How do metalworking fluid defoamers work? Metalworking fluid defoamers eliminate foam by reducing the surface tension of the liquid. When a liquid is subjected to mechanical agitation, impact, spraying, etc., gases in the liquid are trapped in the liquid to form foam. Metalworking fluid defoamers are able to penetrate the surface of the foam and reduce surface tension, causing the foam to become unstable and eventually burst. This prevents foam build-up during the metalworking process and improves the cooling and lubricating properties of the fluid. Metalworking fluid defoamers offer the following benefits: - Can effectively eliminate fo...
