Use of micro mixers for generating foam

摘要

A method for producing a foam using a static micro mixer and a micro mixer for producing a foam are disclosed in this application. The micro mixer is provided with at least one disk (1) which has at least one inlet opening (2) for the introduction of at least one feed stream into a linking channel (3) at least partially provided in a surface of the disk and at least one outlet opening (4) for the outflow of the feed stream from the linking channel (3) into a mixing zone (5) provided in the disk (1). The inlet opening (2) is connected with the outlet opening (4) in a communicating manner by means of the linking channel (3). The disk (1) is adapted to be provided with a cover (15) such that the linking channel (3) is defined as a space between the surface of the disk (1) and the cover (15). The linking channel (3) before opening into the mixing zone (5) is divided by microstruture dividers (6) into sub channels (7). The micro mixer is formed such that a tenside solution as a first feed stream is supplied through the inlet opening (2) into the mixing zone (5), a gas as a second feed stream is supplied into the mixing zone (5), and a foam is produced within the mixing zone (5) by mixing the tenside solution and the gas.
