Street lamp light pole cold galvanizing 12 meters of solar street light and hot dip galvanized what area

Street lamp light pole what is the difference between cold galvanized and hot dip galvanized lamp light pole galvanized process is divided into cold galvanized and hot dip galvanized, galvanized for anti-corrosion anti-corrosion, delay the service life of street lamps, so what is the difference between two kinds of zinc plating? One of galvanizing technology



street lamp light pole cold galvanizing 【 Cold galvanizing is through electrochemical principle of a kind of technology for workpiece surface anti-corrosion treatment. 】 And hot dip galvanized Hot dip galvanized, 镀锌) Also called hot dipping zinc and hot galvanizing, is an effective way of metal corrosion, mainly used for metal structure industry facilities. 】 What is the difference between the

street light pole galvanized process is divided into cold galvanized and hot dip galvanized, galvanized for anti-corrosion anti-corrosion, delay the service life of street lamps, so what is the difference between two kinds of zinc plating? One galvanized process: the difference between the cold galvanizing also known as electric galvanized, is operating electrolytic equipment the workpiece course after degreasing, pickling into the composition of zinc salt in the solution, and connect the cathode electrolytic equipment, placed in the workpiece on the opposite side of zinc plate connected to the anode electrolytic equipment, processing power, operating current from the positive to the negative directional movement, will deposits a layer of zinc on the workpiece; Hot galvanizing is the workpiece after degreasing, pickling, leaching, drying immersed in molten zinc liquid according to time, free to ask. Second light pole outside the indecent difference: electric galvanized appearance all smooth, clear, the electric plating of the passivation technology using color yellow-green give priority to color, colorful. USES white passivation technology of galvanized coating is bluish white or white with green, white passivation process of coating and the sunlight is inevitable Angle slightly. In the Angle of complex workpiece edge areas prone to 'coagulator and gloomy, the zinc layer is thicker. In the shade place form the current corner easily and happen to owe current gray area, the zinc layer is thinner. Without zinc tumor, agglomerate phenomenon such as integral parts. Hot dip galvanized outside disco is a little coarse, galvanized is silvery white, outside indecent prone to process water lines and a few drops of tumor, especially in one end of the workpiece is more obvious. However, slightly crude hot dip galvanized zinc layer is dozens of times thicker than the electric galvanized, anti-corrosion performance is also the galvanized dozens of times, on the price nature also is much taller than cold galvanizing, nothing more than in the long run, rust for up to 20 years of hot galvanizing is better than only 1 - 2 years anti-rust effect of cold galvanizing effect is better, and more extensive market.
