With the increasing use of aluminium sheet, the quality problems in the application process are also beginning to highlight. The appearance of aluminium sheet presents oil pollution is one of the common problems. The following aluminium sheet manufacturer, Mingtai Aluminum Industry, explains why the appearance of aluminium sheet presents oil pollution.
There are two reasons for the quality problems in the use of aluminium sheet. One is the neglect of the staff in the production process, and the other is the improper operation in the later application process. Oil pollution, as one of the common quality losses, can be prevented from operation and equipment application in the production process.
Oil stain does not refer to the stain after the production of aluminium sheet is completed, but after stopping the rolling of aluminium sheet, excessive oil is carried on the surface of aluminium tip, and additional oil is added besides rolling oil film. When the scrap is stopped inspecting and cutting production at the later stage, these visible oil will be found on the surface. A lot of oil is mainly distributed above and below the exit of the mill or at the neck of the roll. After splashing, it drips on the surface of the box, which causes the abnormal situation in the roll cleaner of the rolling mill due to the dripping of oil from the thickness gauge head of the mill. Moreover, the composition of these oils is not only complex but also particularly dirty.
These oil stains on the surface of aluminium sheet will bring a lot of harm to the appearance of aluminium sheet. At the same time, we usually judge the quality of aluminium sheet, oil stain defect is also an important criterion. On the one hand, because the thickness of aluminum plate is thin, it is easy to form foam during subsequent annealing, and because of the excessive amount of oil on the surface, it will form a lot of residues on the surface of aluminum sheet, which will also lead to poor performance in later stage. On the other hand, as long as the appearance of aluminum sheet is clean enough to meet its aesthetic requirements for decoration and packaging materials, otherwise it will be difficult to sell.
Is there no way to prevent these quality problems in production? Of course not. Actually, aluminium plate manufacturers can stop all-round strict inspection of production equipment before producing aluminium plate. If there are a lot of oil stains in the machine and equipment, they should be cleaned in time and the cause should be found and dealt with in time. At the same time, it should also stop cleaning the surface of the production products. If there is oil stain that can not be washed off at the beginning, such products will be scrapped directly. If we let our own oil-contaminated products into storage or into the market, the follow-up control of production quality will only become more difficult, but also there are many after-sales problems that can not be solved.
