Problems solved by technology

Because the lotus leaf is in a normal temperature environment, it will form a very thin air layer, and the water droplets that fall on the lotus leaf also fall on the lotus leaf at normal temperature or even when the temperature is low, but the non-stick pan needs With further heating, the temperature of the pan body will continue to rise and even reach more than 250 degrees. Therefore, only applying this structure to a non-stick pan cannot fully achieve the non-stick effect

Embodiment 1

[0045] Referring to Fig. 1 to Fig. 1 of the accompanying drawings of the description of the present invention Figure 4 As shown, a physical non-stick pan according to a preferred implementation of the present invention is illustrated. The types of non-stick pans include cooking pans, frying pans, frying pans, milk pans, etc. This embodiment takes a frying pan as an example, and its The non-stick pan includes a pan body 1, which can be single-layer or multi-layer. When the pan body 1 is a single-layer material, iron or stainless steel can be used. The alloy elements in the stainless steel are Cr, Ni, Ti, Mn , N, Nb, Mo, Si, Cu and other elements, among which the main alloying element is Cr. For example figure 1 and figure 2 , The pot body 1 is a single layer, including the inner working layer 12. When the pot body 1 is multi-layered, the material can be iron or stainless steel or a composite material, but whether it is single-layer or multi-layer, at least the inner surfac...

Embodiment 2

[0050] A method for making a non-stick pan described in Embodiment 1 is described, comprising the steps of:

[0051] (1) Production of the pot body 1: making the pot body 1 from the plate;

[0052] (2) Sandblasting process: choose abrasives, use compressed air as the power, and spray the abrasives on the surface of the pot body 1, so that the surface of the pot body 1 forms a rough surface of at least micron level;

[0053] (3) Surface treatment: harden and oxidize the surface of the pot body 1, and further form an oxide film with a nanoscale rough porous structure on the rough surface.

[0054] (4) Grinding process: perform mechanical grinding on the preset area of ​​the inner surface of the pot body 1, remove the rough surface at the convex edge 111 in the concave-convex structure 11, and retain the rough surface on the concave area 112 in the concave-convex structure 11, and then The pot body 1 of the non-stick pan is obtained; since there is no non-stick layer on the top ...

Abstract

The invention belongs to the field of kitchen supplies. The invention particularly relates to a physical non-stick pan and a preparation method thereof. The pan comprises a pan body, the inner surfaceof the pan body is made of iron or stainless steel and is provided with a physical non-stick layer, the physical non-stick layer comprises at least a micron-sized rough surface, a nano-sized rough oxidation film of a porous structure is further formed on the rough surface, and the pore diameter of the oxidation film can be contracted and expanded along with the change of the heating temperature;the lotus leaf-like surface structure is combined with an environment where the non-stick pan is located, and the oxidation film is combined with the rough surface to achieve a physical non-stick effect.

Description

technical field [0001] The invention belongs to the field of kitchen supplies, and in particular relates to a physical non-stick pan and a preparation method thereof. Background technique [0002] Conventional non-stick pans need to be sprayed with a chemical non-stick coating on the inner surface of the pan. This chemical non-stick coating is easy to decompose and fail at high temperatures, and the coating will be destroyed quickly under the use of a metal shovel. In order to make non-stick pans not easy to stick, easy to clean, and heat evenly and quickly, there are currently many solutions on the market. For example, CN201020591079.7 represents a solution in which a plurality of grooves are arranged on the top surface of the pot bottom to form lines, and a non-stick layer of Teflon material is set in the grooves. There is also CN201310455227.0, which deepens the design of the groove texture setting, defines the length, width, height and bump size and height of the groove...
