Aluminum alloy non-stick pan with hard surface and processing technology thereof

Abstract

The invention discloses an aluminum alloy non-stick pan with a hard surface. The aluminum alloy non-stick pan comprises an aluminum alloy pan body; a hard oxide film is arranged on the surface of the aluminum alloy pan body; a sintering non-stick layer is adhered to the surface of the oxide film of the aluminum alloy pan body; and the aluminum alloy non-stick pan is processed by a technology which comprises the following steps of: forming, performing finish turning, oxidizing, spraying and sintering. The aluminum alloy non-stick pan can be a stir pan, a steamer, a soup tureen, a frying pan, a milk pan, a pressure cooker, a rice cooker, an electric cooker, and other aluminum alloy cookers. According to the technical technology, the aluminum alloy non-stick pan has the advantages that the finish turning process replaces the conventional chemical cleaning process, so that production efficiency can be effectively improved, and wastewater produced in the production process can be reduced. Meanwhile, by reasonably matching other process steps, the capacity of adsorbing the non-stick layer to the surface of the aluminum alloy non-stick pan can be improved, and the hardness of the pan body can be improved; and the hardness can be 350 to 800 HV, the wear resistance and the thermal resistance can be improved, the corrosion resistance of the surface of the aluminum alloy non-stick pan can be improved, and the service life of the aluminum alloy non-stick pan is prolonged.

Description

technical field [0001] The invention relates to a non-stick pan, in particular to an aluminum alloy non-stick pan with a hard surface and a processing technology thereof. Background technique [0002] The processing technology of the existing aluminum alloy non-stick pan is: forming→cleaning→sand blasting→cleaning→spraying→drying. The disadvantage is that there is oil stain on the surface of the pot body during the stretching process, and the oil stain and oxide layer on the pot body surface must be removed by cleaning before sandblasting. The cleaning process produces a large amount of difficult-to-treat wastewater, which pollutes the environment. In order to increase the adhesion of the non-stick layer, the pot body must be sandblasted to achieve a certain roughness on the surface of the pot body. Since the micropores on the surface of the sandblasted surface have different depths and uneven sizes, the surface of the existing pot body The thickness of the non-stick layer ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: there is oil stain on the surface of the pot body during the stretching process, and the oil stain and oxide layer on the pot body surface need to be cleaned before sandblasting. The cleaning process produces a large amount of difficult-to-handle wastewater, which pollutes the environment

In order to increase the adhesion of the non-stick layer, the pot body must be sandblasted to achieve a certain roughness on the surface of the pot body. Since the micropores on the surface of the sandblasted surface have different depths and uneven sizes, the surface of the existing pot body The thickness of the non-stick layer is relatively thick (about 20 μm or more), easy to fall off, and the surface hardness of the pot body is not high and easy to scrape off, the service life of the non-stick layer is not long
