    you are: the Organization of paint and varnish works

    To colouring of cars by dispersion apply:

    1. Chambers of dispersion with bottom otsosom air without the top overlapping.

    2. Mine raspylitelnye the chambers consisting of two mines, located one against another on distance of 4 m and connected by a working platform and an air line. In each mine there are horizontal cracks for otsosa air, ventilating units and the hydrofilter. The car which is under colouring, gradually moves ahead through installation which is served by seven workers pulverizatorshchikami.

    3 Mobile painting chambers. In this case the car in the course of colouring is, on one places. With a view of economy of paint and varnish materials and achievement of the best quality of a covering are applied on it is young mobile chambers for colouring of an external surface in electric field.

    For drying of the painted cars installations of various designs are used. Konvektsionnye sushilnye chambers for drying of the painted cars appear bulky: their operation is interfaced to the big expense of steam; mobile lamp installations are economic and bulky. So, installation for drying of cars includes 1680 lamps the general capacity of 370 kw the Mobile lamp installations mounted on small rather boards, it is expedient to apply to drying of the separate painted sites atop a post, for example, at colouring in different colours, at correction of defects on separate sites.

    Installations for drying by currents industrial frequencies are economic and perspective. They consist from otdelny the sections-heaters located in the general frame to the cartridge. There are cartridges for drying of lateral and face walls of the car. Cartridges are brought to walls the car at the moment of drying by means of pneumatic devices taken away at car movement. Long drying by currents of high frequency of one paint coat makes 15-30 minutes Temperature on a surface vage on makes 100-130 and #8243; With, therefore it is recommended to dry only the metal skeleton of the car which do not have the internal equipment.

    Mobile thermoradiating chambers are applied To drying also. Radiating panels are warmed with an electricity. Panels are intended for drying of the painted face and lateral walls of cars. At chamber movement face panels are moved apart by means of the mechanism.

    At October car-repair factory in Leningrad in the chamber of such type duration of process of drying of a coat layer gruntov and enamels makes nearby 1 mi shpatlevok-2 ch. In the presence of industrial gas to warm panels with gas more economically; thus gas torches mount in the bottom part of the panel.
