The bonding strength of PTFE is not high, and acidic substances are easy to corrode metal bodies. Once the car body is corroded, it will expand, which will expand the coating and cause the coating to fall off in a large area.

It is understood that many foods eaten daily are acidic foods, including all kinds of meat, eggs, sugar, rice and so on.

2, the use temperature should be below 250℃.

According to the national mandatory standards, PTFE coating is made of PTFE as the main raw material and added with some additives, and coated on the surfaces of aluminum, iron plates and other metals. After high temperature sintering, it can be used as an anti-sticking coating for non-acidic food containers, and the service temperature is below 250℃.

When cooking, many dishes need to be fried, such as fried chicken wings and fried ribs. The boiling point of oil is 320℃. When frying food, the oil is always hot and the temperature is very high, which easily leads to the decomposition of harmful components in the non-stick pan.

3, don't use a shovel, beware of damage.

It is easy to damage the coating of the non-stick pan with a shovel, so that the toxic coating is mixed with vegetables, which is harmful to the health. Before using the non-stick pan, check whether the coating falls off or not to avoid serious consequences.

4. In order to prolong the service life of non-stick pan, it is best to use nylon shovel, wooden shovel and metal shovel with smooth edges and corners.

5. If there are stubborn stains, don't clean them with steel balls, which will destroy the coating on the surface.
