Oiling equipment: functional characteristics of electrostatic oiling equipment
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.
Aluminum foil oiling can be divided into sheet aluminum foil according to its shape. Most of the raw materials for the deep processing of aluminum foil are supplied in roll form. Only a few manual packaging occasions use aluminum foil. Aluminum foil coating oil can be divided into hard foil and soft foil according to its status. Aluminum foil oiled hard foil: Rolled aluminum foil without softening treatment (annealing) and degreasing treatment has a residual surface.
Aluminum foil coated with oil is a stamping material made of aluminum rolled directly onto a thin sheet. The stamping effect of aluminum foil coated with oil is similar to that of pure silver foil, so it is also called fake silver foil. Due to its softness and ductility, aluminum has a silvery-white luster. Aluminum foil can also be printed if the rolled sheet is mounted on offset paper with sodium silicate and other materials.
Knife beam type electrostatic oiling equipment is oil pump directly on the knife beam, through the tiny gap of the knife beam to spray oil. Because the gap of the knife beam is very small, so the oil purity requirements are very high. In actual production, it is impossible to completely clean the annealed strip or the cleaned strip surface with more or less residual iron powder and dust, which will inevitably cause the knife beam (especially the lower knife beam) to be blocked during the continuous production process, resulting in uneven oiling or leakage on the strip surface. Nozzle type electrostatic oiling equipment uses air pressure to pump oil to the nozzle and then sprays the oil out, so even if there are some tiny impurities in the oil under the pressure of the pump and air, the nozzle will not be clogged. Even if there is slight clogging, the impurities can be blown out of the nozzle by directly increasing the air flow, thus ensuring the quality of oiling.
Today, with the flourishing of science and technology, the help of oiling equipment is indispensable for everything from hot water to security doors, to cars or buildings. It can be said that because of the existence of oiling equipment, it not only saves the time we don't need to waste in our daily life, but also reduces some unnecessary expenses and plays a significant role in the direction of our business. On the contrary, some delays in production or mistakes in details may bring adverse effects to ourselves, so it is still important to grasp this link.
