Aluminium Household Foil Jumbo Roll
How to distinguish between good and bad Aluminium Household Foil Jumbo Roll?
In the production process of aluminum foil, there are multiple processes such as rolling, finishing, annealing, packaging, etc., and the interlocking production process. Problems in any link may lead to quality problems of aluminum foil. So how to distinguish the quality of Aluminium Household Foil Jumbo Roll?
According to the experience of aluminum industry people, most of the quality of aluminum foil can be detected directly with your "wisdom eye".However, to distinguish the quality of aluminum foil, we must first understand the common quality defects of aluminum foil. Only when we have an idea, and then check the common aluminum foil quality problems one by one, can we prevent the aluminum foil with quality defects from being put into storage.
1. Aluminum foil bumps
Aluminum foil bump refers to the damage to the surface or end face of the foil after it collides with other objects during handling or storage. The bumps are mostly caused by inattentive foil packaging.
2. Corrosion
The surface of the aluminum foil is in contact with the surrounding medium, and after the chemical reaction or electrochemical reaction occurs, the defects on the surface of the aluminum foil, the corroded surface of the aluminum foil will lose its luster, and in severe cases, gray corrosion products will be produced. Corroded aluminum foil can have a large impact on the aesthetics of the end-produced product.
3. Surface foaming
The aluminum foil with surface bubble defects will have irregular circular or strip-shaped cavity protrusions on the surface of the foil; the raised edges are smooth, the two sides are asymmetrical, and the distribution is irregular. The surface bubbles cause the aluminum foil to be stressed at each point Unbalanced, it is very likely to lead to breakage and downtime.
4. Dark stripes
The dark side stripes mostly appear on the double-helix products, and the dark side has obvious light and dark stripe patterns along the rolling direction, which affects the appearance.
5. Imprints
There are many conditions that can cause imprinting 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 stuck on the surface, the surface of the sleeve or die is not clean or there are local smooth bumps, or the surface of the foil during coiling. There are foreign objects stuck, etc. Imprinted foil surfaces generally have single or periodic depressions or bumps that are easy to identify.
