    you are: Colouring by an electrosedimentation method

    Qualitative colouring by the given method is possible at observance of certain conditions. последствия менингита

    First of all, surface thorough training (removal of extraneous particles and degreasing) is necessary. Новые авто кредит залог автомобиля. A Авто кредит в залог автомобиль /a.

    Steel products for improvement anticorrosive qualities of a covering it is recommended bonderizirovat, thus the layer of a phosphatic film should not be thicker 3 4 microns for preservation elektroprovodnosti. Products from aluminium and its alloys after degreasing in addition process a solution caustic natra and clarify nitric acid with washing by water after everyone; operations.

    Electrosedimentation Process is carried out or at; a direct current, or at constant pressure of a pas electrodes. Regulating force of a current, its pressure and duration of stay of a product in a bath, it is possible to receive a film of any thickness. At colouring by electrosedimentation it is necessary to watch closely temperature of a solution of a bath, duration of a finding of products in a bath, concentration of a solution and it shchelochnostju (an indicator rn). Quality of a covering and for speed of sedimentation is influenced by the nature of a covered product (anode). The best results are given by colouring of steel products, it is more difficult to paint aluminium, the worst results are given by zinc colouring.

    Indicators of a mode of electrocolouring are developed theoretically, and then specified by practical consideration depending on a sort of products and the requirements shown to colouring.

    So, for example, in the thickness 20-30 microns for products from a steel receive coverings, applying constant pressure 15-30 in; for products from aluminium - 100-120 in at density of a current 0,2-0,6 and/dts2; durations of process of 1-3 mines and temperature of painting structure in a bath 20-25°С.

    After product electrosedimentation wash out water and subject to drying at 120-200°С. Before drying the endurance of the painted products on air within 20-25 minutes

    is necessary
