At present, most non stick pots on the market are fluorine-containing coatings. As long as they are regular brands, they are harmless to the human body. Ceramic coatings are made of nano materials, which rely on molecules to achieve non stick effect, but their sustainability is poor. Generally speaking, they can be purchased according to their own needs and preferences, and there is no difference between good and bad.
At present, the non stick pot coatings on the market mainly include fluorine-containing coatings and ceramic coatings. Most of the coatings on the market are fluorine-containing coatings, and the main material is tetrafluoroethylene or silicone resin. In recent years, it was said that fluorine-containing coatings are harmful to human body, but in fact, as long as they are regular brand fluorine-containing coatings, they are not harmful.
However, from a chemical point of view, if the fluorine-containing coating is used, the temperature cannot exceed 260 degrees, otherwise it will destroy the molecular stability and never emit toxic substances. There is no need to worry if it is only cooking. If the cooking temperature reaches 260, the food will certainly be charred.
Ceramic coating is made of nano ceramic technology. It mainly depends on the tightness of its molecules to achieve the effect of non stick pot. It is very green and environment-friendly, can withstand high temperature, has strong corrosivity and high hardness. However, this non stick pot has obvious disadvantages, that is, the non stick effect is not very good and the sustainability is not good.
