Embodiment 1
[0041] This embodiment provides an iron non-stick pan, which is made by the following method:
[0042] First, arc spraying equipment is used on the inner and outer surfaces of the pot body, and a layer of aluminum metal layer with a thickness of 10 μm is thermally sprayed under a spray gun pressure of 0.5 MPa;
[0043] Secondly, after spraying three layers of polytetrafluoroethylene non-stick coating on the aluminum metal layer on the inner surface, the pot body is placed in a tunnel furnace for sintering at a high temperature of 380°C.
Embodiment 2
[0045] This embodiment provides an iron non-stick pan, which differs from the iron non-stick pan provided in Example 1 in that the iron non-stick pan is made by the following method:
[0046] First, sand blast the pot body, put the pot body into the sand blasting equipment, and use 36-mesh brown corundum to roughen the pot body surface to 2 μm under the sandblasting pressure of 0.6 MPa;
[0047] Then, arc spraying equipment is used on the inner and outer surfaces of the pot body, and a layer of aluminum metal layer with a thickness of 10 μm is thermally sprayed under a spray gun pressure of 0.5 MPa;
[0048] Secondly, after spraying three layers of polytetrafluoroethylene non-stick coating on the aluminum metal layer on the inner surface, the pot body is placed in a tunnel furnace for sintering at a high temperature of 380°C.
Embodiment 3
[0050] This embodiment provides an iron non-stick pan, which differs from the iron non-stick pan provided in Example 1 in that the iron non-stick pan is made by the following method:
[0051] First, degrease the pot body, place the pot body in a degreasing agent at room temperature, heat it to 80°C, keep it for 6 minutes, and then rinse and dry it.
[0052] Then, sand blast the pot body, put the pot body into the sand blasting equipment, and use 36-mesh brown corundum to roughen the pot body surface to 2 μm under the sand blasting pressure of 0.6 MPa;
[0053] Then, arc spraying equipment is used on the inner and outer surfaces of the pot body, and a layer of aluminum metal layer with a thickness of 10 μm is thermally sprayed under a spray gun pressure of 0.5 MPa;
[0054] Secondly, after spraying three layers of polytetrafluoroethylene non-stick coating on the aluminum metal layer on the inner surface, the pot body is placed in a tunnel furnace for sintering at a high tempera...
