METHOD OF FOAM PRODUCTION AND DEVICE FOR METHOD EMBODIMENT Russian patent published in 2003 - IPC

FIELD: methods and devices for foam production. SUBSTANCE: pulsing gas flow is divided into uniform, similar in volume elementary components with the help of partition separating gas flow and foam-forming composition. For separation of formed gas bubbles from partition surface, additional break-off force is produced and directed perpendicular to motion of gas flow. Break-off force is produced by partition motion executed in periods between gas supply pulses. Operation of gas flow metering mechanism and mechanism of reciprocating cyclic motions is synchronized by means of control unit. EFFECT: production of homogeneous finely dispersed foam. 10 cl, 1 dwg, 1 tbl
