preparation example Construction
[0030] The present invention also provides a method for preparing an iron-based pot, which comprises the following steps:
[0031] (1) Steel plate, preferably low-carbon steel plate, is stretched into the shape of a pot to form an iron-based pot body 10;
[0032] (2) Form an inner film layer 20-1 on the inner and outer sides of the iron-based pot body 10 by electrochemical deposition;
[0033] (3) forming the outer membrane layer 20-2 on the inner membrane layer 20-1 by chemical deposition;
[0034] (4) Form a non-stick coating 30 inside the iron-based pan with the composite film layer.
[0035] In one embodiment of the present invention, the preparation method of the iron-based pot also includes the step of forming a colored or black organic silicon coating 40 on the outside of the iron-based pan with a composite film layer; preferably spraying a black organic silicon coating , spray atomization pressure 0.2-0.3MPa, film thickness 10-20μm, preferably 12-18μm, then first bak...
Embodiment 1
[0050] Prepared as follows figure 1 The iron-based pan shown in:
[0051] (1) Baosteel DC01 low-carbon steel plate is cut to a size of 1.5mm in thickness and 415mm in diameter, and stretched into the shape of a pot to form an iron-based pot body 10;
[0052] (2) Form an inner film layer 20-1 on the inner and outer layers of the iron-based pot body 10 by electrochemical deposition; put the pot body into an electrolytic solution (10% of aluminum chloride, 0.8% of ferric chloride, 1.2% of zirconium sulfate , butynediol 0.3%, heptadecafluorodecyltrimethoxysilane 0.3%, and the balance is water), adjust the pH value to 5 with 0.1mol / L hydrochloric acid, connect the DC power supply at room temperature, and the pot body The workpiece is connected to the anode, the cathode is connected to the carbon plate, and the current density is adjusted to 1A / dm 2 , through an electrochemical reaction for 20 seconds, an inner film layer 20-1 is formed on the surface of the pot body, and the thic...
