With the use of aluminum plate more and more widely, the quality problems in the process of use also began to highlight, among which the surface of the aluminum plate oil is one of the common problems, the following is to answer why the surface of the aluminum plate oil.

There are generally two reasons for the quality problems in the use of aluminum plate, one is the negligence of the staff in the production process, the other is the improper operation in the later use process. As one of the common quality losses, oil pollution can be avoided from the operation and equipment use in the production process.

Oil pollution does not mean that the aluminum plate is stained after the completion of production, but after the rolling of aluminum plate, the surface of the aluminum tip with too much oil, and also accompanied by the excess oil in addition to the rolling oil film, in the late inspection of the finished product and cutting production, will be found on the surface of the naked eye of the oil. A lot of oil is mainly distributed in the upper and lower parts of the outlet or the neck of the rolling mill. After splashing, it drops on the surface of the box, which leads to abnormal conditions in the rolling mill roll cleaner because the thickness measuring head drops oil. And these oils are not only complicated, they're also dirty.

These oil stains produced on the surface of the aluminum plate will bring a lot of harm to the surface of the aluminum plate. At the same time, we usually judge the quality of aluminum plate, the number of oil defects is also an important standard. On the one hand, because the thickness of the aluminum plate is relatively thin, it is easy to form foam in the subsequent annealing, and because there is too much oil on the surface, a lot of residue will be formed on the surface of the aluminum plate, which will also lead to the late performance is not very good. On the other hand, it is difficult to sell aluminum unless the surface is clean enough to meet the aesthetic requirements of its use as decoration and packaging material.

Is there no way to avoid these quality problems during production? There are several methods:

1. Strict inspection of production equipment can be carried out before the production of aluminum plate. If there is a lot of oil pollution in the machine itself, it should be cleaned and solved in time to find the cause.

2. You can also clean the surface of the product. If in the beginning there is no cleaning off the oil, such products will be scrapped directly. If the products with oil pollution are put into storage or into the market, the subsequent product quality control will only be more difficult, and there are many after-sale problems that can not be solved.

The above is the answer to the oil pollution problem on the surface of the aluminum plate. If you have other opinions or questions, you can contact us.
