An environmentally friendly surface treatment process for non-stick pans

Abstract

The invention discloses an environment-friendly non-stick pan surface treatment process, which comprises the following steps: 1) forming: forming a microporous layer; 2) scanning a laser on the surface of the pan embryo to form a plurality of microporous structures, thereby forming the microporous layer; Porous layer; 3) Spraying a non-stick coating on the surface of the microporous layer: the non-stick coating is filled in the microporous structure. The invention forms a dense and elongated microporous structure on the surface of the pan by scanning the laser microporous forming technology, thereby forming a microporous layer, which not only doubles the surface area of ​​the pan, but also improves the microscopic roughness of the surface of the pan Degree, and then when the non-stick coating is directly sprayed on the surface of the microporous layer, the coating can be filled into the microporous structure, thereby greatly increasing the contact area between the non-stick coating and the microporous layer, thereby improving the non-stick Coating adhesion.

Description

technical field [0001] The invention belongs to the technical field of cooking utensils, and in particular relates to an environment-friendly non-stick pan surface treatment process. Background technique [0002] At present, the sprayed pan embryos in the pot industry basically use surface sandblasting or shot blasting to increase the surface roughness of the pan embryos, so as to improve the adhesion of the non-stick coating on the surface. [0003] Both sandblasting and shot blasting increase the roughness of the surface of the pan by deforming the surface of the pan. Figure 4 It is a partial cross-sectional schematic diagram of a non-stick pan after sandblasting (non-stick coating is not shown), Figure 5 It is a partial cross-sectional schematic diagram of a non-stick pan after shot blasting (non-stick coating is not shown), from Figure 4 and Figure 5 It can be seen from the figure that although the surface of the pan has obvious concave and convex parts under the ac...

[0003] Both sandblasting and shot blasting increase the roughness of the surface of the pan by deforming the surface of the pan. Figure 4 It is a partial cross-sectional schematic diagram of a non-stick pan after sandblasting (non-stick coating is not shown), Figure 5 It is a partial cross-sectional schematic diagram of a non-stick pan after shot blasting (non-stick coating is not shown), from Figure 4 and Figure 5 It can be seen from the figure that although the surface of the pan has obvious concave and convex parts under the action of deformation, if the non-stick coating is directly sprayed on the surface of the pan, the adhesion between the non-stick coating and the surface of the pan will The force is not enough to ensure that the coating is firmly attached to the surface of the pan, and the coating is easy to fall off from the surface of the pan under the impact of hard objects. Therefore, before spraying the non-stick coating, a layer of base oil or Medium oil is used to improve the adhesion of the non-stick coating, but this not only increases the production cost, but is not environmentally friendly enough
