Soft Temper Jumbo Roll Aluminum Foil 14 Micron
We know that aluminum foil is divided into hard state and soft state. Different forms have different functions, and the field of action is also different, but the same is that they may encounter the same problems in the production process.
According to the experience of industry professionals, the quality of aluminum foil can mostly be detected directly with your "wisdom eyes". However, if we want to distinguish the quality of aluminum foil, we should first understand the common problems. Only when we know the quality of the aluminum foil, we can check the common aluminum foil quality problems one by one to prevent the aluminum foil with quality defects from being stored in the warehouse.
There may be bubbles in the product during the production process. The aluminum foil with bubble defects on the surface will have irregular round or strip-shaped cavities on the surface of the foil; the raised edges are smooth, the two sides are asymmetrical, and the distribution is irregular. The surface bubbles make the aluminum foil strip force at various points Unbalanced, it is likely to cause pull-off shutdown.
Sometimes there will be imprints. There are many situations that can cause imprints on the surface of the aluminum foil, such as defects on the surface of the roller or guide roller, or dirt such as metal chips, the surface of the sleeve or tube core is not clean or partially smooth and convex, or the surface of the foil during coiling There are foreign objects and so on.
There is also the problem of bad version. Due to uneven deformation, local undulations on the surface of the foil are called poor plate shape.
Depending on where the defect occurs, different positions have different names. If it is on the side, it is called a side wave. It may also appear in the middle. It is called a middle wave in the middle. Both are called compound waves. The middle part is not called a two-rib wave.
These problems may appear in the production process, but don't worry, these problems have solutions. Whether it is O state or H state aluminum foil can satisfy everyone.
