2. Polytetrafluoroethylene, the scientific name is PTFE, and the English abbreviation is PTFE. It is a polymer compound polymerized from tetrafluoroethylene, which has excellent chemical stability and corrosion resistance. It is one of the best corrosion-resistant materials in the world today. Except molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid fluorine, it can resist all other chemicals and will not change when boiled in aqua regia. Widely used in various occasions that need acid and alkali resistance and organic solvents. It has sealing performance, high lubrication and non-stickiness, electrical insulation, good aging resistance and excellent temperature resistance (it can work for a long time at the temperature of +250℃ to-180℃). Therefore, it is the most commonly used non-stick pan in civil use.
3. Ceramics played an important role in the upgrading process of non-stick pan. The performance of ceramics is stable, and its safety has been fully proved after thousands of years of use. It uses nanotechnology to make the surface of the product dense and non-porous. It refers to the sol-gel process, in which inorganic metal salt or organic alkoxide raw materials are dispersed in a solvent, raw material particles are evenly distributed in the sol through the sol process, then the sol is solidified into a fixed gel, and then the gel is sprayed on the metal surface, and a surface coating is formed through drying or heat treatment. So as to achieve the non-stick effect.
4. Ceramic coated non-stick pan usually has high face value and high safety. It does not contain PTFE and PFOA, and can withstand high temperatures as high as 450℃. Even if the temperature exceeds 450℃, it will not produce harmful smoke.
