Sheet Metal Coating: What are the disadvantages of sheet metal coating and how to improve it?
I'm sure no one is unfamiliar with sheet metal, especially in the market, many customers are beginning to pursue new technologies such as sheet metal oiling, but it still has some problem areas, so I hope reading this article will be helpful to you in order to better utilize its value.
If the amount of oil applied to the sheet metal is too large, it will lead to an impression of the quality of the product. In order not to affect the effect of the later use, it can only be operated in the way of single-sided undercut beam oiling in order to be able to operate better. At the same time, in order to reduce the amount of sheet metal oiling and also to reduce the viscosity of the oil, so many businesses will add a certain percentage of isopropyl alcohol with volatility to the oil. In the process of using the oil, frequent oiling of the sheet metal will lead to blockage of the cutter beam, which will cause leakage and eventually affect the quality of the oiling and indirectly the quality of the product. If the quality of oiling is not stable, it will also cause a large error in the amount of oiling of the same batch of products, which will lead to the customer's request for compensation or return of the product, bringing a burden to the economic efficiency. In addition, sheet metal oiling will cause the cost of oil to increase, bringing greater losses and reducing product efficiency and product rates.
In order to better make the sheet metal oiling have better benefits, there should be further improvement for the above problems. If the sheet metal is oiled on both sides, it will get good effect and feedback, no matter it is aesthetic or stamping effect, and the operator can control it better, so that the error can be controlled within the controllable range, and compared with the previous sheet metal oiling, it is more perfect in using safety, and it does not need Compared with the previous sheet metal coating oil, it is safer to use and does not require additional volatile agent to operate, eliminating the risk of arc pulling and burning, and there is a certain reduction in staffing, so there is no need to have extra staff on site to check the oiling blockage and leakage.
This is the end of the basic introduction of sheet metal coating oil. In order to better play the value of the product, we should consider various aspects when choosing a supplier and start comprehensively, so that not only can the finished product play its greater practical value, but also can bring more economic benefits.
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.
