FIELD: fire-fighting, particularly equipment for generating water-and-air and hardening polymeric foams and for spraying powder materials with the purpose of applying thereof on surface and/or filling cavities with above materials and for fire protection of mobile and stationary ammunition depots.
SUBSTANCE: device for generating and spraying special purpose materials comprises source of compressed air, valves, air-distribution and liquid channels, vessels with initial foam-generation solution ingredients and mixer. Device additionally has foaming hose with nozzle, electromagnetic valves, throttles, flushing system, filters, valves, reducer, mixing ejector, control board and/or program means and, particularly, means for introducing curing agent for polymeric foam hardening and/or hopper and/or stapler and/or dosage means and/or device for single-portion feeding. Structural decisions of total device and its components are also disclosed.
EFFECT: possibility of remote control, increased reliability of foam generation after long-term idle time, increased efficiency of spraying pulp and powder materials.
