Problems solved by technology

There are also materials introducing the use of ceramics and enamel pottery to make non-stick pans. Although they have a non-stick effect, they have not been widely used due to their fragility and damage during manufacture and use.

Embodiment 1

[0015] Embodiment 1: as figure 1 As shown, a metal non-stick pan includes a metal pan body 1, a metal powder sintered layer 2 is arranged on the inner surface of the pan body 1, and dense capillary pores are arranged in the metal powder sintered layer 2. Wherein, the diameter of the capillary pores ranges from 0.1 to 120.0 microns. The metal powder sintered layer 2 is pure metal powder; the particle size of all powders is ≤100 mesh; the metal powder is iron powder.

[0016] Firstly, make a metal disc with a thickness of 2 mm, press metal powder with a thickness of 1 to 3 mm on the metal disc, and put the pressed billet into a high-temperature furnace for sintering. Minutes, through physical and chemical processes such as diffusion, welding, compounding, dissolution, and recrystallization between particles, between particles and metal plates, the fusion and welding between particle powders, particle powders and metal plates form a whole, that is A metal powder sintered layer ...

Embodiment 2

[0018] Embodiment 2: basically the same as Embodiment 1, the difference is: the metal powder sintered layer 2 is a mixture of metal powder and non-metal powder, its weight ratio is 95:5, the metal powder is iron; the non-metal powder The powder is alumina.

[0019] When making, first make a metal disc, press a mixture of metal powder and non-metal powder with a thickness of 1 to 3mm on the metal disc, put the pressed blank into a high-temperature furnace for sintering, and the sintering temperature is 80% lower than the melting point of the metal powder. ℃, sintering for 5-10 minutes, and obtain a metal powder sintered layer 2 with dense capillary pores on the metal disc; then stamp the metal disc into pots of different shapes to obtain the metal non-stick pan.

Embodiment 3

[0020] Embodiment 3: basically the same as Embodiment 2, the difference is: the metal powder sintered layer 2 is a mixture of metal powder and non-metal powder, and its weight ratio is 85:15, the metal powder is copper; the non-metal powder The powder is silicon oxide.

[0021] First, make a metal disc, press a mixture of metal powder and non-metal powder with a thickness of 1 to 3 mm on the metal disc, put the pressed billet into a high-temperature furnace for sintering, and the sintering temperature is 50°C lower than the melting point of the metal powder. After 5-10 minutes, a metal powder sintered layer 2 with dense capillary pores is obtained on the metal circular plate; then the metal circular plate is punched and formed into pots of different shapes to obtain the metal non-stick pan. Finally, the metal non-stick pan is steamed for 1-3 hours with steam at 600° C. after stamping to improve the antirust ability of the pan body 1 .

Abstract

The invention discloses a metal non-stick pan and a method for manufacturing the same, wherein the metal non-stick pan comprises a metal pan body, wherein a metal powder sintered layer is arranged on the internal surface of the pan body, and pores are densely arranged in the metal powder sintered layer. The metal non-stick pan has the advantages that: the metal non-stick pan has the characteristics of metal materials, good chemical stability and hot and cold surging performance; the non-stick pan changes the contact mode of a pan surface and food from conventional contact into multi-point contact; and meanwhile, the pores at the internal surface of the pan absorb and release edible oil when the food is cooked, a layer of oil layer is kept between the cooking food and the pan body so that the cooking food is in a semi-suspension state, and the food and the pan body cannot generate local close contact, so the pan has a non-stick function.

Description

technical field [0001] The invention relates to a pan, in particular to a metal non-stick pan and a manufacturing method thereof. Background technique [0002] The currently used non-stick pan is to coat a layer of fluorine organic matter on the inner surface of the metal pan, and utilize the non-wetting property of the fluorine organic matter to make it have a non-stick function. However, the fluorine organic matter will decompose at high temperature (greater than 250°C), and the fluorine organic matter coating will be gradually damaged. After the fluorine organic matter on the inner surface of the pot is damaged, the pot will lose its non-stick function, and due to the damage of the fluorine organic matter layer Makes bare metal pans less polished and more likely to stick to food. In addition, the decomposed products of the fluorine organic coating are toxic, contaminate food, and are harmful to the human body. Therefore, with people's awareness of this non-stick pan, it...
