galvanisatiezouten

Galvanisatiezouten, also known as galvanizing salts, are chemical compounds used in electroplating processes, particularly for galvanizing iron and steel. These salts are typically metallic salts, such as zinc chloride or zinc sulfate, dissolved in an electrolyte solution. The primary purpose of galvanization is to provide a protective coating of zinc onto a metal surface to prevent corrosion. This process involves immersing the object to be galvanized into a bath containing the molten galvanisatiezouten or an electrolytic solution.

In hot-dip galvanizing, the metal is dipped into a bath of molten zinc, which contains various alloying elements and fluxes, often derived from galvanisatiezouten. In electrogalvanizing, an electric current is passed through an electrolyte solution containing the galvanisatiezouten, causing the metal ions to deposit onto the cathode (the object being plated). The selection of specific galvanisatiezouten and additives influences the quality, thickness, and adhesion of the zinc coating. Common galvanisatiezouten include zinc chloride, zinc sulfate, and zinc ammonium chloride. The purity and composition of these salts are crucial for achieving a uniform and defect-free coating. Impurities can lead to a dull finish, poor adhesion, or increased susceptibility to corrosion. Proper control of bath temperature, current density, and pH are also essential factors in the galvanization process.
