FIELD: technology of mixing gases and liquids; generators for production of hardening foam from compositions of low-molecular and high-molecular agents. SUBSTANCE: proposed foam generator includes cylindrical housing, gas and liquid supply branch pipes and liquid flow disperser located coaxially relative to housing. Branch pipes supplying aqua solution of surfactant and carbamide formaldehyde resin are shifted relative to axis of housing and mixer at distance equal to 5-15% of inner diameter of branch pipe. EFFECT: increased productivity; continuous operation of generator; enhanced efficiency. 4 dwg, 1 ex |
