METHOD AND DEVICE FOR APPLICATION OF SOLID MATERIALS IN FORM OF PARTICLES ON SUBSTRATE Russian patent published in 2009 - IPC B05B7/14 

FIELD: technological processes.

SUBSTANCE: particles are applied on substrate (18), which is coated with a layer (20) of synthetic resin, by means of device (2), comprising pipeline (4), at the first end of which there are facilities arranged for pulling gas pressure, and the second end of which has a free mouth, reservoir (12) for solid materials in the form of particles with specific weight of more than 2 g/cm³ and Venturi nozzle (14) for creation of pressure difference. Reservoir and Venturi nozzle are inbuilt into pipeline so that in working condition due to pressure difference created by nozzle, solid materials in the form of particles from reservoir are transferred into pipeline, swirled and transported to pipeline mouth, from which particles of solid materials come out further and are sprayed into layer of synthetic resin through spray nozzle (10).

EFFECT: invention provides for high evenness of solid material particles application onto substrate.
