Hot dip galvanized and cold spraying zinc different street lamp design

Street lamp light pole galvanized process is divided into cold galvanized and hot dip galvanized, galvanized for anti-corrosion anti-corrosion, extend the service life of street lamps, so what is the difference between two kinds of zinc plating? Differences in traffic lights brand one of galvanizing technology: cold galvanized, also called electricity

light pole galvanized process is divided into cold galvanized and hot dip galvanized. Galvanized to prevent corrosion and prolong the service life of street lamps. What is the difference between these two kinds of galvanizing technology? Traffic lights brand a galvanizing technology difference; Cold galvanizing, also known as electric galvanized. Electrolytic equipment operation, remove the oil on the workpiece and acid, and then the workpiece in the solution containing zinc salt, and connect the cathode electrolytic equipment. Zinc plate is placed on the relative side of the workpiece, and connected to the anode electrolysis equipment. Power on, working current from the positive to the negative of directional movement will deposit a layer of zinc on the workpiece. Hot galvanizing is the workpiece degreasing, pickling, leaching, drying, and then immersed in molten zinc solution for a period of time. As the difference lamp post outside the indecent scene 2: galvanized layer smooth and bright appearance, the colour passivation technology of galvanized coating is mainly yellow and colorful. USES white passivation technology of galvanized coating for for the green, blue and white or white in the sunshine of a inevitable, USES white passivation technology of plating bright slightly. In the corner of the complex workpieces are easy to be corrosive. Electrical burns; And become dim, this part of the zinc layer is thicker. In an internal Angle of zinc layer is relatively thin, very easy to form the dim corner and owe current area. All artifacts, agglomeration, no zinc the phenomena. Hot dip galvanized than slightly thick, galvanized is silvery white. Especially at one end of the workpiece, easy to produce water and a small amount of water droplets. However, slightly rough and clumsy dozens of times thicker than the electric galvanized galvanized zinc layer, its corrosion resistance is also higher than galvanized dozens of times. Naturally, the cost is much taller than cold galvanizing. However, in the long run, antirust period more than 20 years of hot galvanizing antirust period 1 - only 2 years of cold galvanizing effect is better, and more popular in the mall.
