    Essence of the given method is process of sedimentation of a paint on a surface of a metal product at immersing of the last in a bath with simultaneous imposing of an electric current. в продаже msi megabook cx700

    An electrosedimentation Method it is possible to put any (not water) paints, but the most suitable appear vodoemulsionnye and water paints on the basis of various water-soluble pitches. Under the influence of an electric current of a particle of pitch (plenkoobrazovatelja) and the particles of a pigment which are a part of water paints, receive a negative charge, move to positively charged product - to the anode and are besieged on its surface. масло акпп, гидравлические масла, масло кпп, трансмиссионное масло

    This process carries the name elektroforeza; simultaneously with it there are processes elektroliza and elektroosmosa.

    elektroforez defines speed of formation of a deposit in a thickness of a film of a covering. As a result elektroosmosa water from a deposit leaves (is superseded); paint particles are condensed and coat layers stick to a product surface, forming uniform dense. elektroliz solen, being in water, stirs to sedimentation process, therefore at manufacturing of solutions for electrosedimentation apply obessolennuju water - a condensate.

    Installation for covering drawing elektroosazhdennem. Process is carried out in a bath produced more often from stainless steel. The cathode is either the bath case, or the coal in bath coal or steel cores. For improvement of quality of a covering a bath sometimes supply with the device for paint hashing.

    In the beginning of process of electrosedimentation surface sites on which the greatest density of power lines (for example, edges) is observed are painted.

    As separate sites become covered by a paint coat, isolating action of the put layer increases, gradually start to be painted over and other sites of a surface of a product; the film having an identical thickness on all sites of a surface is as a result formed dense besporistaja.
