A lot of people for hot galvanizing and cold galvanized solar lamp posts, no matter from the concept, or process, is not very understanding, blindly choose low price cold galvanizing solar road lamp pole, in fact, the difference between them is not just about the price differs a lot, in the

many people know little about solar energy lamp posts of hot dip galvanized and cold galvanizing, both conceptually and technically. They blindly choose low-cost cold galvanized road solar lamp posts. In fact, the difference between them is not only the price difference, there are other differences. First of all, the technology of the differences between cold galvanizing, also known as electric galvanized. After degreasing and pickling, the workpiece to be included in the solution containing zinc salt, and connect to the cathode electrolytic equipment. Zinc plate and workpiece relative placement, and connected to the anode electrolysis equipment. The power on. Through the current from the positive to the negative directional movement, deposits a layer of zinc on the workpiece. Hot dip galvanizing is the workpiece degreasing, pickling, leaching, drying, and its in molten zinc before go out for a period of time. Compared with the cold galvanized, hot dip galvanized cost is higher, more complex manufacturing process. Second, the difference of appearance of galvanized layer is smooth and bright appearance, the colour passivation technology of galvanized coating is mainly yellow and colorful. Passivation technology USES white coating for for the green, blue and white or white passivation technology USES white coating with the sun's rays into bright slightly under the condition of a certain Angle. It is easy to produce electricity. It was dark, this part of the zinc layer is thicker. , for they are easily formed in the inside corner current produce dark current area, and the area of the zinc layer is relatively thin. The artifacts no zinc tumor, agglomeration phenomenon. Hot dip galvanized appearance than slightly rough, galvanized is silvery white. The appearance of the hot galvanizing prone to process water and a small amount of water, especially in one end of the workpiece. Micro rough hot dip galvanized zinc layer, however, several dozen times thicker than the electric galvanized, high corrosion resistance is better than galvanized dozens of times. Naturally, the price is much higher than cold galvanizing. However, in the long run, antirust period of more than 10 years of hot dip galvanized will only 1 - than antirust period 2 years of cold galvanizing is more popular. If price budget enough, shandong solar street lamp manufacturers still suggest we choose relatively high price of hot dip galvanized. Although the appearance is better than cold galvanized, hot dip galvanized have more advantages in the life and rust degree, also the principle of 'one top money & hot dip galvanized solar street lamps worth buying.
