Process for treating composite plate cooking utensils outer surface oxide film

Abstract

The process of treating the outer surface of composite plate cooking utensil with oxide film treats only the outer aluminum or aluminum alloy surface of composite plate cooking utensil while maintaining the inner surface in metal color. The process includes the following steps: 1. washing the cooking utensil; 2. coating the inner surface with anticorrosive paint; 3. anode oxidizing; and 4. polishing the inner surface mechanically to eliminate the coating and expose metal. The process makes the cooking utensil bright, beautiful, long in service life and practical.

Description

technical field [0001] The invention relates to a method for surface treatment of cookware made of composite board materials, in particular to a process for treating the oxide film on the outer surface of the composite board cookware. Background technique [0002] Traditionally used cooking utensils are mostly made of single-layer metal materials, and many shortcomings have been found in use. For example, the stainless steel pots used recently, although the finish is good and the color is beautiful, but the heating is uneven, easy to stick to the pot, and burn the pot. Insufficient strength and poor heat preservation. [0003] Patent application number 03158377.6 "processing method for multi-layer metal composite boards for making kitchen utensils" provides a manufacturing method for the materials required for making kitchen utensils in order to solve the above problems, and there are many composite board materials for making cookers It is made of copper, steel, stainless s...

Problems solved by technology

[0002] Traditionally used cooking utensils are mostly made of single-layer metal materials, and many shortcomings have been found in use. For example, the stainless steel pots used recently, although the finish is good and the color is beautiful, but the heating is uneven, easy to stick to the pot, and burn the pot. Insufficient strength, poor insulation

[0003] Patent application number 03158377.6 "processing method for multi-layer metal composite boards for making kitchen utensils" provides a manufacturing method for the materials required for making kitchen utensils in order to solve the above problems, and there are many composite board materials for making cookers It is made of copper, steel, stainless steel and aluminum or aluminum alloy. Although the cookware made of this metal composite plate material has good heat insulation, durability and strength, it also has some defects because of the lack of luster of the aluminum material, and it takes a long time. After that, it is easy to corrode and has an unsightly appearance

[0004] In view of the above-mentioned new problems, there is now an oxide film composite board cooker, that is, the inner and outer surfaces of the above-mentioned cooker made of composite board material are treated with surface oxide film, and this method is also limited to aluminum alloys. Or aluminum alloy materials are used as the inner and outer surface layers. If it is other metal surfaces, it cannot be done. In this way, the cookware after surface treatment has luster, good strength, beautiful appearance, and long service life, but its weight is too heavy. Some cooking utensils are hard to hold, it is very inconvenient for consumers to operate and use, and the practicability is poor
