Årsaker og farer for at aluminiumsfoliepulver faller av

Aluminum foil is widely used in modern life and industry, and its processing technology is relatively complex. Various quality problems are prone to occur during the processing, such as wrinkles, string layers, unclean oil removal, aluminiumsfoliepulver faller av, osv.

Denne artikkelen introduserer i detalj årsakene, farer og hvordan unngå pulvertap fra aluminiumsfolie.

Materials and structure of aluminum foil

Aluminum foil is an ultra-thin material made of pure aluminum. Its thickness is usually between 0.006-0.2mm. It is generally used in a wide range of fields such as food packaging, preservation, and baking. The structure of aluminum foil is two layers of film and one layer of aluminum foil. This layer of aluminum foil is the main barrier for packaging food. It can isolate oxygen, water vapor, odor, ultraviolet rays and other adverse factors, and protect the quality and safety of food.

Reasons why aluminum foil powder falling off

Aluminum foil powder falling off is caused by surface corrosion, which may occur during production, transport, storage and use. On the one hand, the material characteristics of aluminum foil make it easily oxidized, and an aluminum oxide film will be produced on the surface. This film will become denser and harder over time, but if it is subject to mechanical friction, extrusion and other forces, this film will The aluminum oxide film will crack and peel off, causing the aluminum foil to fall off. På den annen side, some auxiliaries are added to aluminum foil during the production process, such as processing oil and talcum powder. These auxiliaries will remain on the surface of the aluminiumsfolie and also cause the aluminum foil powder falling off.

The harm of aluminum foil powder falling off

Powder loss from aluminum foil will cause the quality of aluminum powder to remain in food, which may be ingested by the human body. Long-term ingestion may have an impact on human health. Aluminum is a heavy metal, a neurotoxin and a carcinogen. It has two main effects on the human body: First, aluminum is lipophilic and can penetrate cell membranes and enter the interior of cells, interfering with the human body’s central nervous system and specific biochemical reactions. and damage, which may cause minor symptoms such as headache, fatigue, insomnia, memory loss, osv. In severe cases, it may lead to liver damage, pulmonary fibrosis, bone calcium loss, anemia and other diseases; secondly, aluminum will combine with other substances in the body to form Sediments that are difficult to be discharged continue to accumulate in the body, and over time may cause serious diseases such as metabolic disorders, neurological diseases, and malignant tumors.

How to prevent aluminum foil powder falling off

The main methods to avoid aluminum foil powder falling off are as follows:

• 1) Choose aluminum foil brands with reliable quality and aluminum foil products with high quality standards;
• 2) Pay attention to the storage conditions of aluminum foil and avoid prolonged exposure to sunlight, high temperature, humidity and other environments;
• 3) Before using aluminum foil to package food, the surface should be wiped clean with clean water or the food should be baked and heated directly on plates, tableware, osv. instead of aluminum foil;
• 4) When using aluminum foil, be careful not to use metal scrapers to avoid damaging the aluminum oxide film;

Oppsummert, aluminum foil powder falling off is caused by surface corrosion, which may occur during production, transport, storage and use, and may have an impact on human health. Derfor, in daily life, we should pay attention to the correct use of aluminum foil to avoid powder falling off and protect the health of ourselves and our families.
