Embodiment 1

[0025] Example 1: Making a highly wear-resistant non-stick pan

[0026] A. Molding: choose an aluminum alloy plate with a thickness of 3mm and process it into a pot semi-finished product according to the shape of the pot, and then intrude the pot semi-finished product into a surface degreasing solution with a temperature of 80°C for surface degreasing treatment for 3 minutes; the surface The ratio of degreasing solution is: NaOH: 5g / L; NaOH: 5g / L; 2 CO 3 : 25g / L; Na 3 PO 4 12H 2 O: 10g / L; the rest is water.

[0027] B. Anodizing: put the semi-finished product of the pot after the surface degreasing treatment into the anode power supply with a concentration of 180g / L sulfuric acid solution, at a current density of 2A / dm 2 Under the condition of DC current, the anodic oxidation treatment is carried out for 90 minutes at a temperature of 5° C. to form an oxide film with a pore thickness of 25-150 μm.

[0028] C. Permeation: Place the above semi-finished product of the anodi...

Embodiment 2

[0037] Example 2: Making a highly wear-resistant non-stick disk

[0038] A. Molding: choose an aluminum plate with a thickness of 4mm and process it into a semi-finished disc according to the shape of the disc, and then immerse the semi-finished disc into a surface degreasing solution at a temperature of 50°C for 5 minutes; the surface degreasing The ratio of the solution is: NaOH: 6g / L; NaOH: 6g / L; 2 CO 3 : 20g / L; Na 3 PO 4 12H 2 O: 15g / L; the rest is water.

[0039] B. Anodizing: Put the above semi-finished discs after the surface degreasing treatment into the anode of the power supply of sulfuric acid solution with a concentration of 180g / L, at a current density of 3A / dm 2 Under direct current, anodic oxidation treatment is carried out at 0°C for 70 minutes to form an oxide film with a pore thickness of 25-150 μm.

[0040] C. Penetration: Place the above semi-finished anodized disc in a 60% hexafluoroethylene solution at a temperature of 50°C for 10 minutes to allow t...

Embodiment 3

[0042] Example 3: Making a highly wear-resistant non-stick basin

[0043] A. Molding: Use aluminum sheet with a thickness of 3.5mm to process and shape it into a semi-finished basin, and then perform surface degreasing treatment on the semi-finished basin; then immerse the semi-finished basin in a surface degreasing solution at a temperature of 90°C for surface degreasing treatment for 1 minute ; The proportioning of the surface degreasing solution is: NaOH: 5g / L; NaOH: 5g / L; 2 CO 3 : 22g / L; Na 3 PO 4 12H 2 O: 12g / L; the rest is water.

[0044] B. Anodizing: Put the above semi-finished pots after the surface degreasing treatment into the anode with a concentration of 220g / L sulfuric acid solution power supply, at a current density of 4A / dm 2 A direct current power supply is used to perform anodic oxidation treatment for 50 minutes at a temperature of -10°C to form an oxide film with a pore thickness of 25-150 μm.

[0045] C. Penetration: Place the semi-finished product o...

Abstract

The present invention is making process of antiwear nonstick cooker and belongs to the field of daily article making technology. The making process of antiwear nonstick cooker includes the following steps: forming, anode oxidation to form hard oxide layer, permeating, and pore sealing treatment. The antiwear nonstick cooker has the advantages of high nonstick performance, high hardness, high wearresistance and long service life. Besides, the cooker has fewer trend of generating oil smoke and easy cleaning.

Description

technical field [0001] The invention relates to a method for making cookware, in particular to a method for making high wear-resistant aluminum and aluminum alloy non-stick cookware, and belongs to the technical field of making daily necessities. Background technique [0002] Cooking utensils are closely related to people's lives, and most high-end cooking utensils are non-stick cooking utensils. The common practice of non-stick cookware is to spray non-stick paint on the surface of the substrate, and then make the paint dry and cover the surface of the substrate through a certain temperature. Since the paint is sprayed on the surface of the substrate, the bonding ability with the substrate is limited. In order to increase the bonding ability of the paint and the substrate, some methods of sandblasting are used to make the surface of the substrate have a certain roughness before coating the paint. Increase the surface contact area to increase the bonding ability of the coat...
