The lamp pole is the support in the street lamp, which is mainly responsible for the bearing function. The overall service life of the street lamp depends on the lamp pole. Then, how can we ensure the corrosion resistance and good quality of the lamp pole? Therefore, today’s Xiaobian will talk about an important processing means to improve the corrosion resistance and service life of lamp poles: “hot galvanizing”.
Hot dip galvanizing, also known as hot-dip galvanizing and hot-dip galvanizing, is a very effective method of metal corrosion prevention, which is usually used for metal structure equipment in various industries. The main processing process is: after the surface rust of the workpiece is cleaned, it is immersed in the molten zinc solution at about 500 ℃ to make the zinc layer adhere to the surface of the workpiece, so as to prevent the corrosion of the galvanized workpiece.
The anti-corrosion ability of hot-dip galvanizing is very strong, but the anti-corrosion is mainly related to the environment in which the workpiece is used. The anti-corrosion life of the workpiece under different environments will also be different: 13 years for serious pollution in general heavy industrial areas, 50 years for marine corrosion, 104 years in suburbs and 30 years in cities.
In order to ensure the corrosion resistance and service life of the lamp pole, the selected workpiece material is mainly Q235 steel. Q235 steel has good ductility and rigidity, which is the best in the production requirements of the lamp pole. Q235 steel has good ductility and rigidity, but the surface should be hot-dip galvanized and plastic sprayed for corrosion prevention.
Hot dip galvanizing can ensure that the lamp pole has good corrosion resistance and is not easy to corrode. The service life of the lamp pole can be as long as 15 years. Hot dip galvanizing and plastic spraying evenly spray plastic powder on the lamp pole, and evenly attach plastic powder to the lamp pole at high temperature, so as to ensure that the color of the lamp pole will not fade for a long time.
