Electrostatic separation uses charges to separate crushed material particles, commonly used in ore sorting to remove valuable or foreign material. Conducting particles attach to oppositely charged objects, while repulsive force changes the trajectory of falling objects. Electrostatic charges can be positive or negative, and can build up from friction. Electrostatic separation is a preferred method […]
Electrostatic painting uses electrically charged powders to create a glossy finish on metals and some plastics. The process involves creating an electrostatic field to attract the paint to the metal object. The paint is sprayed onto the grounded metal object and then fired in a furnace for a durable finish. The process is environmentally friendly […]
Electrostatic generators produce high voltages by building up a charge through low-power current. They are divided into friction and induction machines, with the Van de Graff generator being an advanced induction type. They are used for demonstrations, medical applications, and physics research. An electrostatic generator is a device that generates high voltages by gradually building […]
An electrostatic precipitator captures pollutants emitted from factories and releases clean gas through a chimney. There are wet and dry types, with the former collecting wet particles and the latter removing dry particles. Efficiency depends on size, collection mechanism, chemical composition, and voltage. Reviews may be prompted by deterioration, changes in production, or stricter regulations. […]
Electrostatic powder coating is a finishing process where dry powder paint is applied to metal by using an electrical charge to create a high-quality, permanent finish. It is commonly used on metals and consumer goods, and can contain various materials. The process offers advantages such as reduced health risks and the ability to reuse unused […]
An electrostatic voltmeter measures surface voltage without transferring excess current charge, ensuring accurate measurements of material tension. It requires no contact and can cancel the electric field between the probe and surface, minimizing arcing and achieving high accuracy. It is commonly used in the industrial sector for various applications. An electrostatic voltmeter measures the surface […]
Electrostatic force is the reaction that holds together the electromagnetic field created by subatomic particles. It is stronger than gravity and occurs when two surfaces come into contact with each other. Coulomb’s law defines the fundamental theories concerning the electrostatic force of attraction. Electrostatic force is the phenomenon that derives from slow or stationary electric […]
An electrostatic field surrounds charged particles and can exert a force on other charged objects. It is measured in newton per coulomb and symbolized as “E”. The direction of the field indicates the direction of the force it exerts on a positive charge. Gauss’ law is a method for calculating electrostatic fields. An electrostatic field […]
