Explain the performance advantages of hot dip galvanizing equipment technology

Hot galvanizing technology is a hot technology developing rapidly since the new century. In recent years, with the rapid development of high-voltage power transmission, transportation, communications and other undertakings, people have higher and higher requirements for protection of steel parts, so the demand for hot-dip galvanized equipment is also increasing. Today's article mainly compares cold galvanizing with hot galvanizing, so that you can better understand the protective performance of hot galvanizing equipment.

Usually, the thickness of cold galvanizing is 5 to 15 degrees Celsius m, while the hot galvanizing layer is usually many times as much as cold galvanizing. The coating capability of hot galvanizing is good, the coating is compact, no organic matter inclusion. Therefore, we can understand that hot-dip galvanization has better anti-atmospheric corrosion ability than electroplating on metal iron.

Technology process of hot dip galvanized layer we can understand for between iron and zinc to the outside of the process of formation of iron and zinc alloy, surface formed in hot dip plating of iron - zinc alloy layer, and makes good combination between iron and pure zinc layer, and cold galvanizing process is used to protect metals to prevent corrosion, therefore using the coating, zinc filler in the method of using any kind of coating coated on the surface to be protected, zinc filler coating after drying, has the content of zinc in the dry coating. Steel is galvanized on the surface again when it is cooled.

Hot galvanizing is steel pipe under the condition of hot dip galvanized iron surfaces process, its adhesion is very strong, not easy to fall off, although hot dip galvanized pipe also can appear the phenomenon of corrosion, but hot dip galvanized corrosion resistance is much higher than cold galvanizing, also known as electric galvanized. Hot galvanizing will not rust in a few years, cold galvanizing will rust in half a year. So it can meet a long cycle of technical and health requirements.
