Appearance quality: The standard requirements of the pot Non-stick coating should be smooth, color, covering power, gloss should be basically uniform, no bubbles, not fall off, but also required coating should be completely hot-melt, no dirty, crack and burst points and other obvious defects.
Base Material Thickness: The product base material should be selected to meet the product performance requirements of aluminum and aluminum alloy materials. The thickness of the matrix material is considered in two aspects: one is to consider the product has a certain strength; the second is to protect Non-stick coating. A non-stick pot used in gas stoves, if the substrate material is thinner, it will make the bottom metal transverse heat conduction area, resulting in uneven thermal distribution, resulting in hot spots. If these hot spots exceed the coating tolerance, it will cause permanent damage to the non-stick coating and shorten the service life of the Non-stick pot.
Non-stick Coating Thickness: The standard requirements of the frying pan, wok, the average thickness is greater than or equal to 25 microns, boiling pot, the average thickness of the milk pot is greater than or equal to 20 microns. This is an important indicator of non-stick pot.
