Embodiment 1
[0029] The pot ceramic coating of the present embodiment comprises the following components by weight:
[0030]
[0031] The preparation method of above-mentioned ceramic coating for pot comprises the following steps:
[0032] (1) Preparation of electroless Ni-P alloy coating steel fiber:
[0033] Place steel fibers with a diameter of 20 μm and a length of 10 mm in dilute HCl with a pH value of 5 and a temperature of 40 ° C for 10 minutes, and stir to remove impurities on the surface of the steel fibers, then rinse with water to remove impurities on the surface of the steel fibers. Acids and impurities;
[0034] Use the steel fiber as an anode to electrolytically remove the grease on the surface of the steel fiber, and then pickle it with dilute HCl with a pH value of 5. After pickling for 20 minutes, rinse the acid solution on the surface of the steel fiber with clean water;
[0035] The treated steel fibers are placed in an electroless plating solution, which includes n...
