Electrostatic oiling equipment is a device that uses high voltage electrostatic to evenly spray antirust oil or other process media on the surface of the plate and strip. Composition: Electrostatic oiling equipment consists of oiling chamber, high voltage electrostatic power supply, oil supply system, electric control system and operating table. The upper and lower oiling knife beams are horizontally installed in the oiling chamber, and the steel plate can pass through freely. The oil supply system quantifies the oil supplied to the oiling knife beam to flow out evenly from the knife edge of the knife beam. The high-voltage electrostatic power supply outputs a negative DC high voltage of about 100 kV, which is applied to the oiling knife beam and generates a high-voltage electrostatic field between the knife beam and the steel plate used as the grounding plate. The negatively charged oil is atomized in the high-voltage electrostatic field and adsorbed on the surface of the steel plate to form a uniform thin oil film. Electrostatic oiling equipment is a high-tech product integrating mechanical, hydraulic, high pressure and electrical control.

Compared with the traditional roller oiling equipment, the electrostatic oiling equipment has the advantages of uniform oiling, oil saving, reliable operation and no environmental pollution. Application areas: Electrostatic oiling equipment is mainly used in steel, machinery and other industries.

 Electrostatic oiling equipment adopts the equipment installed online with the host, which covers a small area, and the steel strip can be wound up after electrostatic oiling. Both old and new equipment are available. Due to the good oiling effect, it is recognized in the cold rolling industry, and the price is much lower than the imported machine, so it is gradually adopted by many manufacturers.

 The positively charged nucleus in each atom neutralizes the surrounding negatively charged electron cloud. When two materials are separated by pressure or frictional contact, the electrons dissociate from the material surface, resulting in an electrostatic zone (corona zone). The surface of the material with reduced electrons is positively charged and the surface of the material with excess electrons is negatively charged. These two charged materials attract surrounding materials with opposite charges to neutralize the electrical properties. If the charged material is electrically conductive, the electrostatic charge will soon be transferred through the material to the ground.

 When the high-voltage electrostatic generator works, the electrostatic discharge electrode is connected to the negative pole, and the metal workpiece is connected to the positive pole and grounded. Under the high voltage of the high voltage electrostatic generator, an electrostatic field is formed between each tip of the electrostatic discharge electrode and the workpiece. When the voltage is high enough, an air ionization zone is formed in the area near the electrostatic discharge electrode tip, and the air is ionized and heated violently, making a dark red halo around the electrostatic discharge electrode tip, and then the air produces a strong corona discharge. The film-forming materials in the coating materials of oil coating equipment are composed of polymer organic compounds, mostly conductive dielectrics and polar materials with low resistivity and low conductivity, which can improve the charging performance of the coating materials. The molecular structure of dielectric consists of polar molecules and non-polar molecules.
