As the use of 2A12 aluminum plate products becomes more and more extensive, the quality problems in the use process also become prominent. Among them, oil stains on the surface of 2A12 aluminum plate products are one of the common problems.

There are generally two reasons for quality problems during the use of 2A12 aluminum plate products, one is the negligence of the staff during the production process, and the other is improper operation in the later use process. As one of the common quality losses, oil pollution can be avoided from operation and equipment use in the production process.

The oil pollution does not mean that the 2A12 aluminum plate products are stained after the production is completed, but after the aluminum plate is rolled, there is too much oil on the surface of the aluminum tip, and also with excess oil except the rolling oil film. When the finished product is inspected and cut for production later, these visible oils will be found on the surface. A lot of oil is mainly distributed above and below the outlet of the rolling mill or at the neck of the roll, and drops on the box surface after being splashed, which leads to an abnormal situation in the roll cleaner of the rolling mill due to oil dripping from the thickness measuring head of the rolling mill, and these oil The ingredients are not only complex but also extremely dirty.

The oil pollution on the surface of 2A12 aluminum plate products will bring a lot of harm to the surface of the aluminum plate. At the same time, when we usually judge the quality of aluminum plates, the number of oil defects is also an important criterion. On the one hand, because the thickness of 2A12 aluminum plate products is relatively thin, it is easy to form foam during subsequent annealing, and because there is too much oil on the surface, a lot of residues will be formed on the surface of the aluminum plate, which will also lead to poor performance in later use. Okay. On the other hand, only the surface of 2A12 aluminum plate products is clean enough to meet the aesthetic requirements of its use as decoration and packaging materials, otherwise it will be difficult to sell.

Isn't there a way to avoid these quality issues at the time of production? Of course not, in fact, manufacturers of 2A12 aluminum plate products can conduct a comprehensive and strict inspection of production equipment before producing aluminum plates. If there is a lot of oil pollution in the machinery and equipment, it should be cleaned in time and the cause should be solved in time. At the same time, the board surface on which the product is produced should also be cleaned. If there is oil stains that cannot be cleaned at the beginning, such products will be scrapped directly. If products with oil pollution are put into storage or into the market, the follow-up product quality control will only be more difficult, and there are also many after-sales problems that cannot be solved.
