What material is the non-stick pan made of? What is the principle? Why not stick?

Material of non-stick pan: Non-stick pan is made of aluminum, stainless steel and other materials. The surface of the pot is coated with a 0.2 mm chemical coating. The main material of this thin chemical coating is Teflon (a few are ceramic coatings or other materials).

Non-stick principle of non-stick pan: Teflon and ceramic coating are coated on the surface of non-stick pan. Teflon coating is mainly fluoropolymer, which has the characteristics of chemical corrosion resistance and aging resistance. Ceramic coating, the main component is silicon dioxide. Silicon dioxide is a natural inorganic product, which is used for the inner wall of pots and pans. The fineness of material particles can reach nanometer level.

Because this material is non-sticky, easy to clean, and has the characteristics of corrosion resistance and high temperature resistance, it is widely used in wok, thermos, oven, barbecue board, microwave oven, chemical industry, clothing and other fields.

Matters needing attention in the use of non-stick pan:

1, cannot be dry-burned.

A non-stick pan can't be dried without oil. Generally, you should put proper amount of oil in cooking, and you can't dry the non-stick pan. Without oil, the temperature in the pot suddenly rises, and the PTFE in the coating will become unstable or even decompose. This is the principle that high temperature will have a certain impact on the non-stick pan and it is easy to make the coating fall off.

2. Don't wash the hot pot cold.

Many people are used to washing the pot after dinner, which is a good cleaning habit, but the non-stick pot is not so clean. Because the non-stick pan has two parts, one is the pan body and the other is the coating, it is easy to separate the pan body and the coating when it is cooled after heating.

3. Don't use too much force to clean the tools.

The material of non-stick pan is weaker than ordinary metal pan, so it can't be cleaned with steel balls like iron pan. Cleaning tools that are too hard will damage the coating.

4. Dry when not in use.

When you are not cooking, you should also pay attention to the cleanliness of the cooker. The service life of non-stick pan is not long, so in order to prolong the service life of non-stick pan, you should pay more attention to daily cleaning to prevent additional injuries.
