As we all know, today's
solar street light poles are all hot-dip galvanized to prevent rust and paint peeling, so why do we see that many light poles still rust and lose paint? That's because some bad manufacturers use cold galvanizing; then what is the difference between hot galvanizing and cold galvanizing? Let's explain to you: solar street light pole cold galvanizing and hot galvanizing are both for anti-corrosion , Extend the life of street lights, so what is the difference between them? The difference between the first process: Cold galvanizing, also called electro-galvanizing, is to use electrolytic equipment to remove oil and pickle the workpiece into a solution of zinc salt, and connect the negative electrode of the electrolytic equipment, and place zinc on the opposite side of the workpiece. The plate is connected to the positive electrode of the electrolysis equipment, and the power is turned on. Using the current to move from the positive electrode to the negative electrode, a layer of zinc will be deposited on the workpiece; Immerse it in the molten zinc solution for a certain period of time and then lift it out. The second difference in appearance: The appearance of electro-galvanizing is relatively smooth and bright, and the electroplating layer using the color passivation process is also the main color of yellow-green, which is colorful. The electroplating layer using the white passivation process is bluish white or white and green, and the coating layer of the white passivation process is slightly colorful at a certain angle with the sunlight. In the corners and edges of complex workpieces, it is easy to produce 'electric burning' and become gray, and the zinc layer in this part is thicker. It is easy to form a current dead angle in the inner corner, resulting in an undercurrent dark area, and the zinc layer in this area is relatively thin. The workpiece as a whole has no zinc nodules, agglomeration and other phenomena. The appearance of hot-dip galvanizing is slightly rougher than that of electro-galvanizing, and it is silver-white. The appearance is prone to process water lines and a little drip, especially at one end of the workpiece. However, the slightly rough hot-dip galvanized zinc layer is dozens of times thicker than electro-galvanized, and its corrosion resistance is also dozens of times that of electro-galvanized. , Hot-dip galvanizing with rust prevention for more than 10 years is more popular than cold galvanizing with only 1-2 years of rust-proof effect.
