Problems solved by technology

Although the above cookware can have a certain non-stick effect, it uses stainless steel shot as a roughening method.
Although shot peening can achieve a certain degree of cold work hardening, the stainless steel dust worn during shot peening will adhere to the surface of the pot body, reducing the adhesion of the oxide layer. At the same time, when the oxide layer is partially damaged, the stainless steel dust and metal base material will form a galvanic cell causing increased corrosion
The surface after anodizing is not raised, but a microporous structure is formed, and the non-stick effect of this microporous structure is not very good

Embodiment 1

[0040] Example 1: The base material of the pot body is an aluminum plate, and the silk thread used for spraying is a medicinal wire material containing nano-sized particles, and the medicinal wire contains stainless steel particles. This method is used to obtain an aluminum-nano, micron-particle stainless steel spray layer-non-stick wax The lotus leaf-like non-stick structure of the texture layer structure.

[0041] In this embodiment, step 5) after spraying, place it in a sintering channel at a temperature of 350° C. for sintering for 20 minutes to obtain a finished product.

[0042]In the above step 3), the method used for the spraying is supersonic flame spraying; the wire used for the spraying is the medicinal wire material containing nano-sized particles, and the nanoparticles wrapped in the medicinal wire material are sprayed into the inside of the pot. On uneven hills, or directly spray nano-sized particles, the spray angle is controlled at 30°.

[0043] In the above s...

Embodiment 2

[0045] Embodiment 2: The base material of the pot body is an aluminum plate, and the silk thread used for fusion spraying is a medicinal wire material containing nano-sized particles, and the medicinal wire contains inorganic non-metallic particles Al 3 o 2 , using this method to obtain aluminum-nano, micron particle inorganic non-metallic Al 3 o 2 Melting layer-non-stick waxy layer structure imitating lotus leaf non-stick structure.

[0046] In this embodiment, step 5) after spraying, place it in a sintering channel at a temperature of 440° C. for sintering for 5 minutes to obtain a finished product.

[0047] In the above step 3), the method used for spraying is powder spraying; the wire used for spraying is the medicinal wire material containing nano-sized particles, and the nanoparticles wrapped in the medicinal wire material are sprayed to the unevenness inside the pot body. On the small peaks, or directly spray nano-sized particles, the spray angle is controlled at 60...

Embodiment 3

[0050] Embodiment 3: The base material of the pot body is iron or stainless steel, and the silk thread used for spraying is the medicinal wire material containing nano-sized particles, and the medicinal wire contains stainless steel particles. This method is used to obtain aluminum-nanometer, micron particle stainless steel spray layer-not Sticky wax layer imitation lotus leaf non-stick structure.

[0051] In this embodiment, step 5) after spraying, place it in a sintering channel at a temperature of 420° C. for 10 minutes and sinter to obtain the finished product.

[0052] In the above step 3), the method used for the spraying is supersonic flame spraying; the wire used for the spraying is the medicinal wire material containing nano-sized particles, and the nanoparticles wrapped in the medicinal wire material are sprayed into the inside of the pot. On uneven hills, or directly spray nano-sized particles, the spray angle is controlled at 45°.

[0053] In the above step 4), th...

Abstract

The invention discloses nonstick cookware and a manufacturing method thereof, wherein the inner surface of the pot body of the nonstick cookware is provided with an uneven raised structure; a grain structure is distributed on the raised structure; and a nonstick coating covers outside the raised structure and the grain structure. The manufacturing method of the cookware comprises the following steps of: (1) forming the pot body of the cookware; (2) carrying out inner surface treatment on the pot body of the cookware to ensure that the uneven raised structure is formed at the inner surface of the pot body of the cookware; (3) carrying out meltallizing treatment on the cookware blank after being subjected to the roughening treatment to ensure that nanoscale hard metal-based or nonmetal-based grain structure is distributed on the raised structure of the pot body of the cookware; (4) spraying nonstick coatings on the inner surface of the pot body of the cookware after being subjected to the meltallizing treatment to ensure that the nonstick coating covers outside the raised structure and the grain structure; and (5) putting in a sintering channel at a temperature of 350-440 DEG C after the spraying to sinter for 5-20 minutes so as to obtain a finished product. The nonstick cookware disclosed by the invention is good in nonstick effect and abrasive resistance, simple in manufacturing process and suitable for large scale production.

Description

technical field [0001] The invention relates to a non-stick cooker and a manufacturing method thereof, and belongs to the transformation technology of the non-stick cooker and the manufacturing method thereof. Background technique [0002] Since the invention of non-stick pan, it is easy to clean, can easily fry and fry food without sticking to the pan, can minimize oil fumes, and can reduce modern people's pursuit of green food, low-fat, low-calorie needs. Crowd favorite. However, the current mainstream non-stick pans in the market all rely on spraying a layer of polyfluororesin non-stick coating on the surface, relying on its strong hydrophobicity and low friction coefficient to achieve non-stick food. Once the non-stick coating falls off, the non-stick performance will be greatly reduced. Through the study of lotus leaves, it is found that there are many tiny papillae on the surface of lotus leaves. The average size of the papillae is about 10 microns, and the average s...
