In the production process of patterned aluminum plate, quality problems are easy to occur due to equipment or personnel operation errors. Here, the small editor summarizes the common quality problems of oil pollution as follows. I hope that aluminum plate manufacturers can pay attention to this problem.
Oil stain is a common quality problem: oil stain refers to excessive oil on the surface of aluminum tip after rolling And the excess oil other than the rolling oil film is brought, and the surface oil visible to the naked eye in the process of slitting production and finished product inspection. These oils are mainly caused by the throwing, splashing and dripping on the box surface at the roll neck or at the outlet of the rolling mill, the abnormality of the roll cleaner of the rolling mill and the dripping of oil from the thickness measuring head of the rolling mill, and they are often dirty and have complex components.
This kind of oil stain will bring great harm to the surface of aluminum plate: first, because most of the finished aluminum plate is used as decoration or packaging materials, it must have a clean surface; Second, its thickness is thin, and it is easy to form bubbles in the subsequent annealing. Moreover, due to the large amount of oil, too much residue is formed at this place, which affects the use. The quantity of oil stain defect is a very important index to evaluate the quality of aluminum foil.
Solution: strictly check the production equipment before production. If it is found that there is too much oil in the equipment, clean it in time and find out the reason. At the same time, clean the plate surface of the production products. If the products cannot be cleaned, discard them. The products with oil are prohibited from entering the warehouse and entering the market.
Scratches are frequent customers of quality problems: scratches, scratches and bumps are intermittent or continuous single groove scars on the surface of aluminum oxide plate. It is generally generated when the sharp object contacts the surface of the foil and slides relatively.
Main causes: sharp defects on the surface of roller and guide roller, or hard sundries; There are pointed defects or sundries on the mechanical guide rollers and guide paths of shearing, coiling and slitting.
6 scratch: the scars distributed in bundles (or groups) on the surface of the box material due to the relative sliding or staggering between the edges and surfaces of the objects or after the surface to surface contact.
