Metalworking Fluids: Stability and size analysis using the Turbiscan

Metalworking fluids (MWFs) are a family of industrial liquids used to reduce the temperature of and/or lubricate metal workpieces while they are being machined. MWFs are the key element to ensure the productivity and reliability of metal processing, as well as the lifespan of machines used in these industries. Current technologies used for MWF analysis (visual observation, DLS…) do not provide direct aging information as these methods may be limited and not representative (sample preparation/dilution, based only on particle size…). Obtaining trustworthy information on emulsion stability requires an analytical solution that offers a direct measure of occurring phenomena and does not rely on external stress.

In this context, we would like to introduce the Turbiscan technology:

Scheme Turbiscan Backscattering Principle

The Turbiscan uses Static Multiple Light Scattering (SMLS) to detect particle migration and size variation in liquid dispersions. Transmission (T) and Backscattering (BS) signals measured are related to particle size and concentration and their variation over time is a sign of occuring destabilization.

The Turbiscan has been used worldwide for over 25 years to detect all kinds of destabilizations such as coalescence, flocculation, creaming, sedimentation at an early stage. Emulsions, suspensions, or foams can be studied at full concentration range (up to 95%v/v) without dilution or sample preparation.

How can the Turbiscan assist in the characterization of metalworking fluids?
