Because the poles of high pole lights meet the high-weight solar panels, high-torque wind, and even some engineering needs to place heavy batteries on the poles, if there is a problem with the pole, then it may constitute a pole. The twisting or breaking or even hurting industry and personnel. The hot-dip galvanizing can effectively ensure that the light pole is not corroded, ensure the normal strength of the light pole for up to 25 years, and effectively maintain the various components it carries.

So what is the principle of hot-dip galvanizing to prevent corrosion of light poles? Anyone who has studied chemistry should know the principle of "sacrificial anode". Zinc is a more active metal element than iron. When the combination of zinc-iron (zinc- When the iron compound is corroded to form the electrode, the electrons will be transported to the iron and then the iron is maintained, sacrificing zinc. At the same time, zinc easily forms a fine oxide layer in the air, which protects zinc from deeper oxidation.

To be clear, in the air, zinc constitutes a fine oxide to prevent deeper oxidation; in the electrolyte (rain water, sea water, river water, acid and alkali corrosion) zinc acts as a sacrificial anode, so no matter what the situation, zinc Will protect the iron element from corrosion.

With the advancement of science and technology, the theoretical level and technological level of the hot-dip galvanizing industry have been greatly advanced, and now many scientists have proposed more complex principles of zinc-iron compounds, zinc-sulfur compounds, and zinc-phosphorus compounds. And apply these theories to the new generation of galvanizing process, and use technology to manipulate the emergence of favorable compounds to avoid disadvantages.
