HV generator Electrostatic powder anticorrosive coating spraying use for can

electrostatic powder coating spraying is a process that uses high voltage to atomize and charge paint particles, which are then attracted to a grounded object, forming a smooth and consistent coating.  The principle of electrostatic spray coating is based on the laws of electrostatics, which state that opposite charges attract each other.

In electrostatic spraying, the liquid paint is pumped into a nozzle, where it is atomized by a high-pressure air stream.  The paint particles are then charged by an electrode in the nozzle, which is connected to a high voltage power supply.  The charged particles are attracted to the grounded object, which is placed in the spray path, and form a uniform and thorough coating.

The key feature of electrostatic spray coating is its ability to achieve high transfer efficiency, which means that a high percentage of the paint is deposited on the target surface, minimizing overspray and waste.  This is due to the electrostatic attraction between the charged particles and the grounded object, which ensures that the paint is evenly distributed and adheres well.

Another advantage of electrostatic spray coating is its ability to coat complex shapes and geometries, such as corners, edges, and small surfaces.  This is because the charged particles are attracted to all parts of the object, regardless of its shape or size.  Electrostatic spray coating is also faster and more efficient than conventional spray painting, as it requires less paint and produces less overspray, reducing cleanup time and costs.

Overall, electrostatic spray coating is a highly effective and economical way to achieve high-quality and durable coatings on a variety of materials and surfaces.  Its unique characteristics make it a popular choice for many industries, such as food and beverage cans,  automotive, aerospace, and furniture manufacturing, where high performance and efficiency are critical.

How to Use:

The electrostatic high voltage generator is divided into an input terminal and an output terminal.   The input terminals of our conventional electrostatic high voltage generator are red and white wires. The red lines connect battery positive electrode and white poles are negative. The wire diameter of the input terminal is smaller than the output terminal. Various terminals can also be customized.
