<p>The method comprises supplying a first component as free-flowing mass to a mixing device over a supply device and then conveying within the mixing device in a main stream direction, and supplying a second gaseous component as sub-stream to the mixing device. The both components in the mixing device are mixed and consist of a foam material after cooling the mixture. The first component is supplied as free-flowing phase under pressure to inlet side (11) of a venturi nozzle (10), which is relaxed in the venture nozzle. The method comprises supplying a first component as free-flowing mass to a mixing device over a supply device and then conveying within the mixing device in a main stream direction, and supplying a second gaseous component as sub-stream to the mixing device. The both components in the mixing device are mixed and consist of a foam material after cooling the mixture. The first component is supplied as free-flowing phase under pressure to inlet side (11) of a venturi nozzle (10), which is relaxed in the venture nozzle. The second gaseous component is sucked through the lower pressure in the mixing area of the venturi nozzle and the mixture leaves as two material mixtures of the both components at the exit side of the venturi nozzle. The first component comprises a plastic, a mineralized substance or a metal and is produced from a metal foam, rock foam or plastic foam. The first component comprises elastomers. The hardening of the mixture is physically carried out after discharging from the venturi nozzle through cooling and/or physically cross-linking or chemically carried out through polycondensation. A cross-linker is supplied as further component on a place on which a low pressure or turbulence dominates through suction of the mixing area of the venturi nozzle. The two mixing devices operated according to venturi principle are arranged parallel to each other in flow direction. The mixture is supplied in a circuit or supplied section wisely in a circuit in such a way that the mixture emerging at the exit side of the mixing device operated according to the venturi principle is supplied partially again to the inlet side of the mixing device. The second gaseous component is supplied to the main flow direction about radial direction of the mixing device. The mixing device is partially tempered. An independent claim is included for a device for the production of foams.</p> |
