Definitions
- FIG. 1 shows a partial schematic cross section through an embodiment of the device with a prechamber, resonance chamber and part of the amplitude transformer.
- the ultrasound transducers are therefore excited by a process computer-based frequency generator, the voltage emitted by the element being used as a control variable, so that the ultrasound transducers always work with maximum amplitude. Due to the bandwidth of the possible frequencies, the resonance space must have a certain size, which at the same time guarantees the desired high flow rate.
- the device according to the invention was able to reduce the bulk density by about 10%.
- the loading of polyol with carbon dioxide could be increased tenfold from 1.2 g per 20 ml by using the device according to the invention.
- the foams produced using the device are characterized by a lower density and a lower thermal conductivity or better insulation.
