Electrostatic Spray Equipment and Their Use
Electrostatic spray equipment is used in a wide variety of applications to protect materials, to control and handle the heat, to assist in the efficient transfer of electric current, and to prevent corrosion. These machines are widely used in the protection of electrical and electronic equipments. These machines are capable of spraying the protective coatings required for many applications. These coatings protect against electrostatic discharges. It is important to know more about electrostatic spray equipment so that you can make the right decisions for your business.
This article describes electrostatic spray equipment and its protective coatings. The protective coating prevents electrostatic discharge when electrostatic spray systems are in operation. Electrostatic spray systems are special discharge devices containing metal electrodes that are arranged in a cyclone, between the two opposite conductors. explain how electrostatic spray charge effects the flow efficiency of electrostatic spray finishing operations.
Describe how the electrostatic spray effect maximizes transfer efficiency. Describe the relationship between electrostatic spray guns and hvlp coating. Describe the common characteristics of electrostatic spray guns and electrostatic spray equipment. Discuss the relationship between electrical charges and electrostatic charges.
An electrostatic spray gun consists of a low-powered electrically charged needle attached to a compressor which supplies compressed air as a source of air pressure. A small but powerful nozzle attached to a fitting at the end of a hose is used to inject paint into the electrostatic spray gun cartridge. Electrostatic paint spray guns are used to achieve smooth, even coatings on metals and other materials using conventional air or water-based paint systems.
Electrostatic spray equipment consists of three major parts: electrostatic hvph machines, electrostatic, high resistive systems, and electrostatic resistive systems. Each of these parts has a variety of different configurations and requirements. The electrostatic hype machines are used to provide electrostatic protection to metal shafts and components in high-performance electrostatically controlled environments. Some examples of electrostatic hvph machines include pump seals, pump relays, and angle grinders. The electrostatic, high resistive systems are used in electrostatic applications in which there is a need for low-cost, effective, high-volume transfer of power with a consistent, repeatable control over a wide area.
An electrostatic spray equipment system consists of four main components: electrostatic hvph machines, electrostatic, high resistive systems, and electrostatic resistive systems. Electrostatic hype machines are electrostatic machines that provide a method of controlling and spraying materials using a direct electrical current. Common application areas for this equipment are coating materials with a protective coating to reduce corrosion and termites, hardening materials, sealing materials and sealants, bonding agents and thermosetting agents. Electrostatic, high resistive systems act as barriers against the flow of electric currents, protecting these materials from damage by electrostatic discharges. These systems are often required in areas where the voltage requirement exceeds the typical voltage rating for connecting conductors; they also protect against excess moisture and corrosive effects of electricity.
Electrostatic spray equipment uses an electrostatic discharge head and an ionizing needle. The electrostatic discharge head resembles the shape of a basic electrostatic vacuum cleaner hose. When the tip of the ionizing needle touches the surface to be protected, a discharge occurs, creating a charged field that prevents the charge from flowing to the object or towards the machine. The discharge travels in a straight path away from the source of the discharge and usually results in a minimum level of charge transfer to the object, which causes the charge to either dissipate or become static.
Electrostatic coatings are available in a variety of forms, including rubberized polyester coatings and many other forms such as melamine and fiberglass. All types of electrostatic applications require the application of a protective coating, whether it is applied to metal, wood, ceramics, plastics or any other material. The coating serves to prevent the rapid transfer of charge to the object and prevents corrosion and other harmful reactions to the material. Commonly used coatings are PVD, PTZ, and CCA. There is a wide range of coatings available to meet different electrostatic requirements.
