    • Colouring by douche. Concentration of steams

    you are: Colouring by douche

    Concentration of steams is supervised by the special device, the executive mechanism of the device operates automatically the throttle-valve regulating removal from the tunnel of surpluses of steams.

    Entrance and target platforms are equipped with air veils to prevent hit of steams of solvent in a shop premise.

    That in installation the turbulences of a steam-air mix accelerating evaporation of solvent from a surface of products could not be formed, installation zones separate from each other demountable partitions with cuts for pass of products. Such partitions named silhouettes, are established also on target and entrance apertures for reduction uletuchivanija steams from installation.

    In installation is available two pumps: one serves, as it was already specified, for giving of a paint from a tank to contours and nozzles; the second periodically pumps over a paint through the filter and the heat exchanger and submits solvent to a tank with a paint, and as required and to special contours and the nozzles intended for washing of installation. Solvent after washing merges, and it further use for cultivation of painting structure.

    Duration of douche makes 1-2 mines, endurance time in steams of solvent of 8-10 mines for gruntov and 12-14 mines for enamels. Working viscosity changes depending on a sort of paint and varnish materials and a configuration of products.

    Than longer the product in solvent steams, and the more their concentration stays, the is more thin the covering film turns out. Concentration of steams of solvent in the steam tunnel should be approximately on 50% less than the bottom limit of explosibility. For example, the bottom limit of explosive concentration solventa makes 50%, and recommended concentration - 20-25/m3
