Non-stick pot is one of the indispensable cooking utensils in the family kitchen, because the surface of the uniform coating of a metal coating, heat insulation, oil dredging effect, so that food materials will not stick to the metal surface. Acturally the sparkling particles inside is aluminum paste. Look at a set of data.

The technical requirements of the coating are: 280 ℃ baking for 15 minutes, 230 ℃ temperature to reach more than 2 hours of hot hardness, cooling after two hours of boiling water without decolorization, do not fall off. It should be understood here that non-stick pan coatings need high temperature resistance, boiling resistance, thermal hardness, and coating cooling hardness. That brings technical requirements to throw out the resin, the effect of additives, aluminum and silver paste itself must have high temperature resistance, boiling resistance.

The sparkle aluminium paste of Zhangqiu has these two properties, because the surface is regular, the ratio of diameter to thickness is uniform, and it diffuses evenly when heated, so as not to cause oxidation, coiling and film bursting due to local high temperature, so as to ensure the stability of the film and the long service life.
