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 do not know much about solar energy lamp posts hot galvanizing and the concept and process of cold galvanizing. In fact, the difference between them is not only the price is different, also in other aspects. First, the process differences between cold galvanizing, also known as electric galvanized. After degreasing and pickling, the workpiece to be included in the solution containing zinc salt, the solution and electrolytic equipment connected to the cathode. Zinc plate and workpiece relative placement, and connected to the anode electrolysis equipment. When power on, through the directional movement of the current from the anode to cathode, zinc layer will be deposited on the workpiece. Hot dip galvanizing is the workpiece degreasing, pickling, immersion and drying, and then will immerse in a certain time in molten zinc solution, then remove them. Compared with the cold galvanized, hot dip galvanized cost is higher, more complex manufacturing process. Second, the difference of appearance smooth and bright appearance, galvanized passivation of color plating mainly yellow-green and color. White passivation process of coating for blue and white or white and green, white passivation process of coating with the sun's rays into bright slightly under the condition of a certain Angle. At the corner of the complex workpiece prone to; Electrical burns; It's getting dark, this part of the zinc layer is very thick. Easily formed in the inside corner current, lead to owe current grey areas, the zinc layer is very thin. The workpiece without zinc tumor and agglomerate. Compared with the electricity galvanized, hot dip galvanized look slightly rough, is silvery white, prone to process line and a few drops of tumor, especially at one end of the workpiece. However, slightly rough, hot dip galvanized layer several times thicker than the galvanized layer, its corrosion resistance than electric galvanized layer a few times, its far more natural than cold galvanized layer. However, in the long run, the 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 enough budget price, solar street lamp manufacturers in shandong still suggest you choose a relatively high price of hot dip galvanized. Despite the appearance may not be as cold plating, hot dip galvanized has advantages in terms of life and rust. ; You get what you pay for the truth; Solar street lamps of hot dip galvanized worth buying.
