Standard for non-stick pan:
1, thickness of matrix material. The matrix material of the product should be aluminum and aluminum alloy materials that can meet the performance requirements of the product. The minimum thickness of the substrate of the frying pan and frying pan is 2.0mm and 2.5mm respectively; The minimum thickness of the base material of the cooking pot and the milk pot is 1.6 mm and 1.8 mm respectively.
2. Appearance quality. The standard requires that the non-stick coating in the pot should be smooth, with uniform color, hiding power and luster, no bubbles and no shedding. It is also required that the coating should be completely hot-melted, without obvious defects such as dirt, cracks and explosion points.
3. Scratch resistance. This is an index to test the ability of the coating to resist various hard substances and the hardness, curing degree and adhesion of the coating itself.
4, non-stick coating thickness. The standard requires that the average thickness of frying pan and frying pan is greater than or equal to 25 microns; The average thickness of the boiling pot and the milk pot is greater than or equal to 20 microns. This is an important index of non-stick pan, which will affect the service life and performance of non-stick pan. In addition, the surface of the non-stick pan needs to be cleaned by sandblasting before painting to increase the roughness of the surface and increase the adhesion, thus increasing the adhesion fastness and scratch resistance.

Common non-stick pan types:
1, Teflon non-stick pan. Teflon is a transliteration of Teflon. Teflon is a registered trademark used by DuPont in a series of fluoropolymer products.
Subsequently, DuPont developed a series of products except teflon PTFE resin, including teflon; AF (amorphous fluoropolymer), Teflon; FEP (fluorinated ethylene propylene resin), Teflon; FFR (fluoropolymer foam resin), Teflon; NXT (fluoropolymer resin), Teflon; PFA (perfluoroalkoxy resin), etc.
1954, Colette, the wife of French engineer Marc Gregoire, had a whim that Teflon, a non-stick material used by her husband to coat fishing lines to prevent knots, would have a good effect if it could be used in frying pans. The "non-stick pot" that saved countless modern housewives was born.
2, ceramic coating non-stick pot. 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. Nano-technology is used to make the surface of the product dense and pore-free, so as to achieve the effect of non-sticking.
