Why are soda cans made of aluminum?

The pop-top can is made of aluminum alloy, and its inner wall is coated with some organic coatings to isolate the aluminum alloy from the beverage. In the process of processing, it is inevitable that the protective coating is not applied in some places, or is applied too thinly, so that the aluminum alloy on the inner wall of the can comes into contact with the beverage. Over time, the aluminum element gradually melts.

In particular, it is more harmful when the cans contain acidic or alkaline beverages. It can be seen that cans should not be drunk often. Drink more, especially children with strong growth and development and the elderly with poor excretory function, it is better to drink less. Aluminum cans are generally coated with a protective layer on the inner wall, and acidic substances generally will not corrode aluminum cans during the shelf life, but not necessarily if the shelf life is exceeded.

Precautions for using aluminum products:

1. Most families have already used iron pot for cooking, and using iron pot for cooking is good for health, because iron is very good for preventing human anemia. However, there are still a few families who use aluminum pots for cooking. Aluminum pots are not good for health because the melting point of aluminum is relatively low. When cooking, the aluminum in the aluminum pot will enter the food, which is not good for human health.

2. In daily life, try not to use aluminum tableware, because in a relatively high temperature environment, aluminum ions can easily escape from aluminum tableware and enter food. In particular, when aluminum products come into contact with iron tableware, it will promote the release of aluminum ions. After eating foods containing too much aluminum, it will affect the health of the body.

3. When making pickles, it is best not to use aluminum products, because vinegar, salt and other seasonings will be put in the pickles. The strong acid and alkali have a corrosive effect on aluminum products. After the aluminum element in aluminum products enters the food, it will have an impact on health.
