Embodiment 1

[0037] Such as figure 1 and figure 2As shown, the production method of the lipophilic and non-stick cookware is processed for aluminum alloy cookware to form cookware with good lipophilicity and non-stick properties, which specifically includes the following steps:

[0038] a. Prepare the cooker: prepare the cooker body 1 for molding;

[0039] The formed aluminum alloy cooker body 1 can be processed by deep drawing, spinning, casting and other processes, wherein the aluminum alloy selected for processing such as deep drawing and spinning is 3XXX series aluminum-manganese alloys, such as 3003, 3103A, 3004, etc. Casting and other methods must use cast aluminum alloys with a silicon content (Si)<8%, and the inner surface of the cast cookware must be turned to remove the oxide scale formed during the casting process. In addition, it is also possible to purchase directly from the market without producing it yourself.

[0040] a1. Perform mechanical treatment on the surface of t...

Embodiment 2

[0068] The scheme of this embodiment is roughly the same as that of Embodiment 1, except that the cooking utensil body 1 adopts a frying pan with a diameter of 26 cm, the material is 3103A aluminum alloy, the forming method is deep drawing, the inner surface is finely sanded, and a sulfuric acid hard anode is used Oxidation treatment, the flame temperature is 1800 degrees Celsius, using propane-pure oxygen as fuel, the burning time is 6 seconds per square decimeter of surface, and the flame is moved repeatedly for about 30 seconds, and the cooker body is kept at 1 Cover with soybean oil at 500°C.

Embodiment 3

[0070] The scheme of this embodiment is roughly the same as that of Embodiment 1, except that the cooking utensil body 1 is a frying pan with a diameter of 32 cm, the material is 3103A aluminum alloy, the forming method is spinning, the inner surface is finely sanded, and a sulfuric acid hard anode is used. Oxidation treatment, the flame temperature is 1200 degrees Celsius, using liquefied petroleum gas-pure oxygen as fuel, the burning time is 9 seconds per square decimeter of surface, and the flame is burned repeatedly for about 75 seconds. Cover with soybean oil at 400C.

Abstract

The invention provides a manufacturing method for an oleophilic non-stick cooker, belongs to the technical field of cookers, and solves a problem that carcinogens harmful to a human body are generatedduring a production or using process of an existing non-stick cooker. The manufacturing method for the oleophilic non-stick cooker comprises the following steps of a, preparing the cooker, namely preparing a molded cooker body; b, carrying out hard anodic oxidation treatment, namely carrying out hard anodic oxidation treatment on the surface of the cooker body in order to form a hard anodic oxidation film; c, burning, namely carrying out burning treatment on the hard anodic oxidation film on the cooker body by adopting flame with the combustion temperature of at least 1200 DEG C; d, coveringwith an oil layer, namely keeping the cooker body in a set high temperature state, and covering the surface of the hard anodic oxidation film subjected to burning treatment with edible oil; and e, cooling, namely cooling the cooker body to the room temperature. The manufacturing method for the oleophilic non-stick cooker has an advantage of good safety.

Description

technical field [0001] The invention belongs to the technical field of cooking utensils, and relates to a method for manufacturing lipophilic and non-stick cooking utensils, in particular to a method for manufacturing lipophilic and non-stick cooking utensils with a micro-nano structure. Background technique [0002] Existing non-stick cooking utensils often add one deck non-stick coating to guarantee its non-stick property on the inner surface of cooker, can be divided into two classes according to whether it has organic coating, the one, the inner surface has polytetrafluoroethylene ( PTFE) is the representative coating of non-stick cookware, and the other is various cookware that does not contain organic coatings. [0003] The surface of the non-stick pan with polytetrafluoroethylene (PTFE) has very low surface tension, so it has excellent non-stick properties. However, the sintering temperature of the non-stick pan during the production process is 400-450 ° C, and the o...
