Aluminum foil oiling: What are the ways of aluminum foil oiling?
Aluminum foil is a kind of stamping material with metal aluminum directly calendered into a thin sheet, using professional technology, it can be stamping effect similar to pure silver foil stamping effect, so some people also call it fake silver foil. Due to its soft and ductile texture, aluminum also has a silver-white luster. It can be made into foil sheets under certain circumstances, and the calendered sheets can be printed by laminating them on offset paper with substances such as sodium silicate. With the development of the economy, other uses have been discovered, such as oiling of aluminum foil. I hope that after reading this article you will discover the magic of aluminum foil coating and the advantages and disadvantages of each method.
In the past, there were two main ways to apply oil to aluminum foil, one was manual oiling and the other was spray oiling. The former method, also known as manual foil oiling, involves the use of an oiling brush or oil solution applied manually to the foil in motion during the operation of the equipment, which has the disadvantage of being a worker factor. Since this is mainly a manual way of oiling the foil, it will produce an uneven layer of oil and dripping, and there are also certain operational and safety hazards. For the latter type of foil oiling, the foil is oiled mainly by pressure, which is a harmful factor that does not guarantee the overall quality and can damage the flatness of the foil if the pressure is not well controlled, thus requiring a great deal of skill and equipment performance from the operator.
In order to reduce the labor intensity of the operator, to guarantee the integrity and quality of the foil and to increase the productivity, many suppliers have started to improve the process of continuous oiling of the foil with a simple and reliable equipment, which, after improvement, basically enables continuous oiling without damaging the integrity of the foil. One of the biggest highlights of this improvement is the addition of rubber. An oiling roller is set horizontally in the frame below the roll, and this foil oiling device can be in contact with the rubber roll. A lifting device is also set below the oiling groove to reduce the operator's labor intensity, so that the final presentation of the product and the operation are greatly enhanced.
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.
The electrostatic oiling equipment consists of oiling chamber, high voltage electrostatic power supply, oil supply system, oil circuit heating and circulating system, electric control system and operating table. The upper and lower oiling knife beams/nozzles 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/nozzle to flow evenly from the knife gap of the knife beam and nozzle.
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.
