Process Introduction

Among various coating methods for protecting steel substrates, hot-dip galvanizing is an excellent one. It is a process in which zinc is in a liquid state and undergoes complex physical and chemical reactions, resulting in the deposition of a thick layer of pure zinc on steel and the formation of a zinc iron alloy layer. This plating method not only has the corrosion resistance characteristics of electroplated zinc, but also has a zinc iron alloy layer. It also has strong corrosion resistance that cannot be compared to electroplated zinc. Therefore, this plating method is particularly suitable for various strong acid, alkali mist and other highly corrosive environments.

principle

The hot-dip zinc layer is formed by zinc in a high-temperature liquid state in three steps:

1. The iron-based surface is dissolved by zinc solution to form a zinc iron alloy phase layer.
2. The zinc ions in the alloy layer further diffuse into the matrix to form a zinc iron miscible layer.
3. The surface of the alloy layer is enveloped by a zinc layer.

advantage

Advantages of hot-dip galvanized cable tray: It has excellent anti-corrosion performance, long durability, much longer service life than ordinary cable trays, high industrialization level of production, and stable quality. Therefore, it is widely used in outdoor environments that are severely corroded by the atmosphere and difficult to maintain.

Performance characteristics

(1) A thick and dense pure zinc layer covers the surface of the steel, which can prevent the steel substrate from coming into contact with any corrosive solution and protect the steel substrate from corrosion. In the general atmosphere, a thin and dense layer of zinc oxide is formed on the surface of the zinc layer, which is difficult to dissolve in water and therefore plays a certain protective role on the steel substrate. If zinc oxide forms insoluble zinc salts with other components in the atmosphere, the anti-corrosion effect is more ideal.

(2) Featuring an iron zinc alloy layer and dense bonding, it exhibits unique corrosion resistance in marine salt spray and industrial atmospheres.

(3) Due to its strong bonding and zinc iron compatibility, it has strong wear resistance.

(4) Due to the excellent ductility of zinc, its alloy layer adheres firmly to the steel substrate, allowing hot-dip plated parts to undergo various forming processes such as cold stamping, rolling, drawing, bending, etc. without damaging the coating.

(5) After hot-dip galvanizing of steel structural components, it is equivalent to one annealing treatment, which can effectively improve the mechanical properties of the steel substrate, eliminate the stress during the forming and welding of steel components, and facilitate the turning processing of steel structural components.

(6) The surface of the hot-dip galvanized parts is bright and beautiful.

(7) The pure zinc layer is the most plastic layer of hot-dip galvanizing, with properties similar to pure zinc and ductility, making it flexible.

Application scope

The application of hot-dip galvanizing has also expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding, etc.), agriculture (such as sprinkler irrigation, heating rooms), construction (such as water and gas transportation, wire conduit, scaffolding, houses, etc.), bridges, transportation, and other fields in recent years. Due to its beautiful appearance and good corrosion resistance, hot-dip galvanized products are becoming increasingly widely used.
