摘要： The invention concerns a semi-continuous method for preparing an emulsion of droplets of a phase A in a phase B, including the following steps: (i) mixing an amount of phase A and an amount of phase B using a multi-shaft mixing system comprising at least one scraping agitator, so as to obtain a dispersion of phase A in phase B with a volume concentration of phase A higher than 74%; (ii) diluting the dispersion obtained in step (i) by adding an additional amount of phase B, and mixing using said multi-shaft mixing system, so as to obtain an emulsion of droplets of a phase A in a phase B.

摘要： The system and the method are used to determine the process viscosity (&mgr;) of a fluid (22) in a film metering device (10) used to form a film (24) to be applied on a substrate (20), such as a paper web or any other suitable flexible materials. The apparent shear rate ({dot over (&ggr;)}) of the fluid, indicative of the flow field, may also be calculated. These parameters are calculated using a pressure profile representing the pressure of the fluid between a transfer roll (12) and a metering rod (30) which controls the thickness of the coating film (24). The torque (T) applied on the metering rod (30) is also measured and taken into account in the calculations. The system and method allow the process viscosity (&mgr;) to be easily and accurately determined during the operation of the film metering device (10) without the need of testing the fluid in an external device and attempting to extrapolate the results to the process.
