Non-stick coating spraying process for non-stick pan with concavo-convex patterns

Abstract

The invention discloses a non-stick coating spraying process for non-stick pan with concavo-convex patterns. The process comprises the steps of firstly performing sand blasting treatment on an inner surface of a pan body blank to increase the adhesive force between the inner surface and a coating and prolong the durability of a coating film, then performing bottom oil non-stick coating spraying, and then performing polishing treatment on the positions of convex patterns by using abrasive paper so that the positions of the convex patterns have no bottom oil coating and the decorative effect ofthe convex patterns is highlighted; and finally, performing surface oil non-stick coating spraying on the pan body blank so as to increase the non-stick property at the positions of the convex patterns of the product. The non-stick pan manufactured by the process is firm and durable, and the effects of durability and non-stick in the full screen are reached since the bottom oil coating is under the protection of the complete surface oil coating, so that the problems of adhesion of convex positions and easy falling of the coatings at the concave positions in the prior art are effectively avoided, the problem that the coating is shoveled by a turner is also improved, and the full screen non-stick performance, the service life and the attractiveness of the pan body are greatly improved.

Description

technical field [0001] The invention relates to a manufacturing process of kitchen cookware, in particular to a non-stick coating spraying process for non-stick pans with concave-convex patterns. Background technique [0002] At present, the outer surface of the stainless steel pot sold on the market is generally polished and smooth. It is very beautiful when you first buy it, but after a long time, the outer surface of the pot body will be scratched, dirty, blackened, etc. Food crumbs stick to the outer surface of the pot, making cleaning troublesome. So now there is a non-stick pan with concave and convex patterns on the market. This design increases the heat absorption area, fast heat transfer, and long life. Moreover, the pattern on the outer surface is in contact with the stove, which can prevent slipping and scratches. function, while achieving the purpose of easy cleaning. [0003] However, the current non-stick coating spraying process with concave and convex patte...

Problems solved by technology

[0003] However, the current non-stick coating spraying process with concave and convex patterns is to directly spray the non-stick coating on the pan body blank, and use sandpaper to polish the raised pattern positions, so that there is no non-stick pan in the raised pattern positions. The protection of the coating, and the coating at th...
