The advent of "non-stick pan" has brought great convenience to people's lives, people do not have to worry about the heart when cooking meat will accidentally burn, fried fish fillets stick to the wall of the pan. Non-stick pan why not stick? Here is a detailed talk for you, I hope to help you! The reason why the non-stick pan is not stick is that the layer of paint called "Teflon" on the bottom of the pan. This substance is a general term for fluorine-containing resins, including polytetrafluoroethylene, polyperfluorinated ethylene propylene and various fluorine-containing copolymers, because these compounds have the advantages of high temperature resistance, low temperature, self-lubricating, chemical stability, it is widely used in non-stick cookware, waterproof breathable materials (such as waterproof clothing), leather, automotive parts, and microwave oven popcorn bags. From the point of view of health: non-stick pan is not as healthy as iron pan. The current non-stick pan, does not appear in what form, not which country, its main materials are Teflon, advanced mixed with antioxidants and stabilizers to improve the high temperature resistance of PTFE. In short, they do not crown what name, said what substance, its main component is not without PTFE. Although the maximum cooking temperature will not exceed 180 degrees, the Teflon coating will always break down bit by bit under frictional heating. A non-stick pan with a long life can't be used for frying or barbecuing PIZZA. In this case, the loss of polytetrafluoroethylene can be reduced to the minimum, and the most harmful to the human body is also the least. Buy a non-stick pan, do not use this pan for frying, after all, accelerate the volatilization of Teflon materials is not good for health.
