In the production process of insulation aluminum foil belt, quality problems are prone to occur due to equipment or personnel operation errors. Here, the common quality problems of aluminum industry are summarized as follows, and we hope that the production department can pay attention to this problem.

Oil pollution is a common quality problem: oil pollution refers to the excessive oil on the surface of aluminum tip after rolling, and the excess oil except rolling oil film, which can be seen by naked eyes in the process of slitting production and finished product inspection. These oils are mainly caused by throwing, splashing, dripping on the box surface at the roll neck or above and below the exit of the rolling mill, abnormality of the roll cleaner of the rolling mill, oil dripping on the thickness measuring head of the rolling mill, etc., and are often dirty and complex.
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 cause. At the same time, clean the plate surface of the production products. If the products that cannot be cleaned are scrapped, it is forbidden to put them into the warehouse and enter the market.
Scratches are frequent customers of quality problems: scratches, abrasions and bumps are intermittent or continuous, single groove like scars on the surface of insulation aluminum foil. Generally, it is produced when the sharp object contacts with the foil surface and slides relatively.
