Defu colored aluminum plant pool dedicated plate heat exchanger

Defu Shandong Aluminum Plant colored pool supply dedicated plate heat exchanger! With the continuous development of the aluminum surface treatment process, the electrolytic coloring, electrophoresis coating products due to good decorative, and therefore are widely used at home and abroad, especially in the architectural aluminum industry. Coloring process control precautions colored aluminum production in actual operation, the coloring time control requires accurate to the second, the temperature range of control ± 2 ℃, PH value control between ± 0.1 is appropriate, the smaller the fluctuation range of the process indicators better, under normal circumstances other process parameters, the depth of color is determined according to the time. In general, try to slightly deeper point. Because in the subsequent pure water, lighter colors will be reduced. Coloring feed trough should enter sideways until smooth material, no bubbles only after power. FIFO, to ensure consistent color profiles two ends. Order energized: must be thoroughly cleaned after oxidation, and then immersed in the bath up and down several times to enhance and standing 1min, followed by power and slowly at a rate of 0.35V / S from zero to the required voltage, this time current density rises rapidly to a maximum limit of Phytophthora (1.5-2A / dm2)), shall be de-energized when coloring supplies. Coloring complete lifting immediately, into the next wash tank and then the color, not the colored slots remain, strictly control the transfer time, PH value of the water tank after coloring requirements ≥3. Defu plate heat exchanger to further expand the scope and scale applications in the petroleum, chemical, metallurgy and other industrial areas of production. In recent years the industry from the market point of view, plate heat exchangers have been gradually replaced the traditional heat transfer equipment, has become the mainstream sales market. .
