8011 Household Using Food Aluminum Foil Rolls
Aluminum foil can really be seen everywhere in our lives. We can use it when we cook, we can use it when food is fresh, and we can even use it when we make desserts.
We collectively refer to these aluminum foils as household aluminum foils. We understand its uses, but we don’t know much about its production process. We don’t know what problems we will encounter in the production process. We can learn it together today. .
Not to mention other problems encountered in the production process, just talk about oil removal. In the production process, the oil removal may not be clean. Once the surface of the finished product is oily, it cannot be used.
Although modern rolling mills have improved the oil baffle, roll cleaner, tuyere, etc., the amount of oil carried at the exit during the aluminum foil rolling process has been reduced, but it cannot completely eliminate the oil on the surface of the exported aluminum foil. It needs to be in the production process. In the regular inspection, once the aluminum foil is oily, it will be shut down for inspection.
For many domestic rolling mills, oil dripping and slinging on the export side are common phenomena due to equipment accuracy, design defects of the rolling mill itself, and equipment aging.
As long as there is oil dripping on the outlet side and the oil is thrown on the material surface, it will inevitably affect the consistency of the degreasing of the annealed aluminum foil, causing some aluminum foil coils to either be excessively degreasing to cause oxidation and compaction, or degreasing is not clean, which will give downstream companies Causes quality problems in the application compound.
The quality statistical information feedback from the market shows that the aluminum foil oxidation scrap caused by excessive annealing and degreasing accounts for about 20% of the annual defective products, and the unqualified products caused by poor degreasing account for about 10%. The data shows that in many cases, in order to prevent oil removal, the industry generally adopts extending the annealing time and increasing the annealing temperature to increase the oil removal.
All of the above are the problems that will occur when the oil is not clean in the production process. I hope that these contents can let you know more about its production process.
Aluminum Foil Jumbo Roll Food Grade Specification We all know that aluminum foil can be divided into many types according to its use, and it can also be divided into food grade and industrial grade.
