The melting point range of zinc-aluminum-magnesium alloy coating is relatively wide, and the temperature of the plating bath needs to be accurately controlled to ensure that the alloy can fully melt and achieve good wettability during the formation of the coating. Too low a temperature will cause the alloy to be incompletely melted, thus affecting the quality of the coating; too high a temperature will easily cause violent volatilization and oxidation of the plating solution, thereby affecting the composition and quality of the coating.
The content and temperature of alloy elements will affect the wettability and surface tension of the zinc-aluminum-magnesium alloy plating solution. The wettability determines whether the coating can fully adhere to the surface of the substrate. The greater the surface tension, the easier it is to cause defects such as uneven liquid and missed plating.
At high temperatures, the metal elements in the zinc-aluminum-magnesium alloy plating solution will react with the substrate to form intermetallic compounds and slag. These reactions will affect the quality of the coating and the performance of the substrate, so the content and reactivity of alloying elements need to be controlled to avoid defects caused by adverse reactions.
The elements in zn-al-mg steel tube Europe are easily oxidized at high temperatures. The oxidized oxide film can play a protective role, but it will also affect the quality and performance of the coating. In particular, magnesium oxide is not dense, which can easily cause oxidation to continue and produce the effects of oxidation. Therefore, it is necessary to control the formation of oxide film and its impact on the coating.
Zinc and magnesium have high volatility at high temperatures and easily form steam and ash-like substances, which affect the surface of the plating solution and the quality of the coating. In particular, zinc is the most volatile, and measures need to be taken to inhibit the volatilization of zinc.
The hot plating process of zinc-aluminum-magnesium plating solution requires precise control of temperature, enhanced wettability, control of reactivity and oxidation characteristics, reduction of volatility and other factors to ensure the quality of the coating. These are the key to formulating process measures and solving production difficulties. If you want to inquire about zn-al-mg steel tube quotes, you can contact our sales.
