We all know that general steel will corrode if it is exposed to outdoor air for a long time, so how to avoid corrosion? Before leaving the factory, the street light poles need to be hot-dip galvanized and then sprayed with plastic, so what is the galvanizing process of the street light poles? Today, galvanized street light pole factory TIANXIANG will take everyone to understand.
An indispensable part of the manufacturing process of street light poles is hot-galvanizing. Hot-dip galvanizing, also known as hot-dip galvanizing and hot-dip galvanizing, is an effective metal anti-corrosion method and is mainly used for metal structural equipment in various industries. After the equipment has cleaned the rust, it is immersed in a zinc solution melted at about 500°C, and the zinc layer is adhered to the surface of the steel component, thereby preventing the metal from corroding.
The anti-corrosion time of hot-dip galvanizing is long, but the anti-corrosion performance is mainly related to the environment in which the equipment is used. The anti-corrosion period of equipment in different environments is also different: heavy industrial areas are seriously polluted for 13 years, oceans are generally 50 years for seawater corrosion, Suburbs can be as long as 104 years, and cities are generally 30 years.
In order to ensure the quality, reliability and durability of solar street light poles, the selected steel is mainly Q235 steel. The good ductility and rigidity of Q235 steel are the best in the production requirements of light poles. Although Q235 steel has good ductility and rigidity, it still needs to be treated with hot-dip galvanized and plastic-sprayed anti-corrosion treatment. Galvanized street light pole has good corrosion resistance, not easy to corrode, and its service life can reach 15 years. The hot-dip galvanized spraying evenly sprays the plastic powder on the light pole, and evenly attaches the plastic powder to the light pole at high temperature to ensure that the color of the light pole will not fade for a long time.
The surface of galvanized street light pole is bright and beautiful, and it has the function of combining steel Q235 and zinc alloy layer tightly, and exhibiting unique anti-corrosion, anti-oxidation and wear resistance in marine salt spray atmosphere and industrial atmosphere. Zinc is malleable, and its alloy layer adheres firmly to the steel body, so galvanized street light poles can be cold punched, rolled, drawn, bent, etc. without damaging the coating. The galvanized street lamp has a thin and dense layer of zinc oxide on the surface of the zinc layer, which is difficult to dissolve in water. Therefore, even in rainy days, the zinc layer has a certain protective effect on the street lamp, which prolongs the life of the street lamp.
