devices for preparation of highly-dispersed homogenized mixtures at preset concentration of components. SUBSTANCE: proposed plant includes reservoir 1 for second component (solution of foaming agent), cock 2, pump 3, pressure gauge, 4, cock 5, filter 6, cock 7, throttle valve 8 forming passage for delivery of second component, foam generator 9, compressed air source 10, cock 11, reservoir 12 for second component (carbamide formaldehyde resin), cock 13, pump 14, pressure gauge 15, filter 16, cock 17, throttle valve 18, mixer 19, reservoir 20 for third component (solution of hardener), cock 21, pump 22, pressure gauge 23, filter 24, cock 25, throttle valve 26, compressed air source 27 and mixer 27. Units 12-18 form passage for delivery of first component, units 20-26 form passage for delivery of third component. EFFECT: enhanced reliability and accuracy; improved quality of product due to enhanced accuracy of metering and control of flows; improved quality of mixtures. 2 cl, 2 dwg |
