Precautions for aluminum foil transportation
Aluminum is a highly reactive metal, and it is prone to oxidation when exposed to the natural environment for a long time. Therefore, aluminum foil should be protected from moisture as much as possible. The finished double-zero aluminum foil is very soft and easily deformed. A slight collision or scratching or pressing will cause the aluminum foil to deform, and its performance will decrease. Serious collisions or scratching or pressing may cause the aluminum foil to be scrapped. Therefore, the aluminum foil should be placed in the air or placed in a soft place. On the surface of the water platform, the aluminum foil box cannot be tilted or turned upside down, and the aluminum foil roll can only be hoisted horizontally, and cannot be tilted or moved vertically.
When transporting and using aluminum foil, beware of die deformation.
Features of aluminum foil
1. It has good mechanical properties and can meet the requirements of automated packaging machinery, but lacks flexibility. The tear strength is low, and it is easy to break at the fold. It is easy to process and can be compounded with plastic film, paper and other packaging materials, which is convenient for coloring and printing.
2. Light weight, which helps reduce transportation costs.
3. It is not hot sticky, resistant to acid and alkali, and not easy to curl.
4. It has metallic luster, good shading, strong light reflection, and the luminous rate can reach 95%.
5. It is not easy to corrode, has good barrier properties, is moisture-proof and waterproof, and has strong air tightness and fragrance retention.
6. The shape is stable under high and low temperature, and the temperature [1] does not expand or shrink when the temperature is -73~371℃.
Solutions to the sticky problem of double zero aluminum foil
The principle of the double zero foil finish annealing system: usually the purpose of double zero foil annealing is to obtain a certain degree of plasticity; the other is to obtain a bright, clean and oil-free surface quality. In this annealing system, due to the high temperature and the burning of grease, the decomposition and oxidation of the carbon chain of the oil film occurs, causing pollution of the aluminum foil and causing yellow-brown oil spots.
