Nonstick development

The advent of the "non-stick pan" has brought great convenience to people's lives. People no longer need to worry about burnt when cooking meat, and fish fillets stick to the wall of the pan when frying fish. This kind of non-stick pan has nothing to do with the appearance of the ordinary pan. It is just that an extra layer of PTFE is coated on the inner surface of the pan, using the excellent thermal, chemical and easy-to-clean properties of PTFE. And non-toxic properties make this popular kitchen utensil. PTFE is known as the "Plastic King" with good chemical resistance and aging resistance, and "Aqua regia" is also difficult to corrode. Ordinary plastic products are prone to aging. Something that looks good will crack or even break after three to five years or ten years. Products made by "Plastic King" can be placed outdoors and exposed to the sun and rain. , There is no damage in twenty or thirty years. So it is widely used in life and chemical industry.
