Problems solved by technology

However, the organic matter of fluorine will decompose at high temperature (greater than 250°C), and the coating of the organic matter of fluorine will be gradually damaged. After the organic matter of fluorine on the inner surface of the pot is damaged, the non-stick pan will lose its non-stick function. The role of the surface of the metal pan makes the surface of the exposed metal pan less smooth and more likely to stick to food
In addition, the decomposition products of fluorine organic coating are toxic, contaminate food, and are harmful to human body.

Abstract

The invention discloses an enamel non-stick fry pan, which comprises a pan body. A ceramic overglazing layer is enameled on the inner surface of the pan body and provided with dense pores. The enamel non-stick fry pan has the advantages of having the characteristics of ceramic materials and having the excellent chemical stability and the performance of cold and hot sudden change; the non-stick fry pan changes a mode that the surface of the pan is contacted with food, and is changed into multi-point contact from surface contact; and simultaneously, the pores of the ceramic surface adsorb and release edible oil during cooking food to maintain a layer of oil film between the cooked food and the pan body, so that the cooked food is in a semi-suspension state, and the food and the pan body arenot locally closely contacted, and thus the enamel non-stick fry pan has the non-stick function.

Description

technical field [0001] The invention relates to a pan, in particular to an enamelled non-stick pan. Background technique [0002] The currently used non-stick pan is to coat a layer of fluorine organic matter on the inner surface of the metal pan, and utilize the non-wetting property of the fluorine organic matter to make it have a non-stick function. However, the organic matter of fluorine will decompose at high temperature (greater than 250°C), and the coating of the organic matter of fluorine will be gradually damaged. After the organic matter of fluorine on the inner surface of the pot is damaged, the non-stick pan will lose its non-stick function. The effect of the surface of the metal pan makes the surface of the exposed metal pan less smooth and more likely to stick to the food. In addition, the decomposed products of the fluorine organic coating are toxic, contaminate food, and are harmful to the human body. Therefore, with people's awareness of this non-stick pan,...
