zinkspuiten

Zinkspuiten, also known as zinc spraying or thermal zinc spraying, is a process used to apply a protective zinc coating to metal surfaces. This is typically done to prevent corrosion, particularly on steel structures. The process involves melting zinc wire or powder using a heat source, such as an electric arc or a flame, and then atomizing the molten zinc into fine particles. These particles are propelled at high velocity onto the prepared surface of the object to be coated. The impact of the particles causes them to flatten and bond, forming a dense, adherent coating.

The thickness of the zinc coating can be controlled by adjusting the spray distance, nozzle speed, and the amount of zinc applied. Zinkspuiten is a versatile coating method that can be applied to a wide range of shapes and sizes, including large structures like bridges, offshore platforms, and storage tanks, as well as smaller components. The zinc coating acts as a barrier protection, preventing corrosive elements from reaching the underlying metal. It also provides sacrificial protection, meaning that if the coating is scratched or damaged, the zinc will corrode preferentially, protecting the steel from rust. This process is often used in conjunction with other protective measures, such as painting, to provide enhanced and long-lasting corrosion resistance.
