Zinc spraying machine is a kind of equipment used to provide anti-corrosion protective layer, mainly used for the surface treatment of cast iron pipes, especially suitable for corrosive soil environment. Through arc spraying technology, the arc between the two continuous metal wires is used as a heat source to melt the metal wires, and then the high-speed airflow is used to atomize the molten metal into particles, and accelerate these particles, so that it is deposited on the surface of the workpiece to form a protective layer. This technique is an important branch of thermal spraying technology in surface engineering and can effectively protect materials such as cast iron pipes from corrosion.
Hot zinc spraying is a specific zinc spraying process, which uses an arc formed by short circuit between two continuous positive and negative wires to melt metal, and atomizes the molten metal with compressed air or other airflow to form a coating technology. The metal coating formed by this process can be firmly attached to the surface of the workpiece, providing anti-corrosion protection.
The working principle of zinc spraying machine involves a number of components, including frame, clamping rotary mechanism, lifting mechanism, zinc spraying mechanism, electro-hydraulic control system and flue gas recovery system. The zinc spraying machine is not only used for the protection of cast iron pipes, but also widely used in other fields requiring anti-corrosion treatment.
