preparation example Construction

[0036] In another typical embodiment of the present application, a method for preparing an anti-corrosion cooker is also provided, the preparation method comprising: forming an anti-corrosion layer 20 on the first surface of the base layer 10 of the cooker by a solid-phase reaction method, Thereby the antiseptic pot is obtained.

[0037] The above preparation method forms the anticorrosion layer 20 by using the solid phase reaction method, which not only improves the preparation efficiency of the anticorrosion layer 20, but also due to the particle rearrangement, material transfer, gas filling and crystallization between the constituent elements of the anticorrosion layer 20 during the solid phase reaction process grain growth, the formed anti-corrosion layer 20 is uniform in composition, and there is no potential difference. Not only will there be no pitting and perforation phenomenon that occurs in the anti-rust iron pan with nitriding and oxidation treatment, but also it has...

Embodiment 1

[0044] Fe and TiO 2 Powders with a particle size of 5 μm were prepared by electrolysis, respectively, and the above two powders were mixed according to a mass ratio of 7:3 to obtain 70 g of mixed powders.

[0045] Add 0.03g sintering aid HBO to the mixed powder 3 And 29.97g organic solvent polyethylene glycol is mixed further, obtains slurry;

[0046] The slurry is coated on the first surface of the iron pan base layer 10 to form the iron pan body;

[0047] Put the iron pan green body at 400° C. for sintering, and sinter at this temperature for 60 minutes to obtain an anti-corrosion pan, wherein the anti-corrosion layer 20 has a thickness of 5 μm.

Embodiment 2

[0049] Fe and Al 2 o 3 The powders with a particle size of 15 μm were respectively prepared by electrolysis, and the above-mentioned various powders were mixed according to a mass ratio of 6:4 to obtain 98 g of mixed powders.

[0050] Add 2g of organic solvent sodium carboxymethyl cellulose to the mixed powder for further mixing to obtain a slurry;

[0051] The slurry is coated on the first surface of the low-carbon steel pot base layer 10 to form a pot body; wherein, the first surface is a sandblasting surface formed by sandblasting, wherein the roughness of the sandblasting surface is 1.2 μm;

[0052] The pot body was sintered at 900° C. for 5 minutes at this temperature to obtain an anti-corrosion pot, wherein the anti-corrosion layer 20 had a thickness of 50 μm.

Abstract

The invention provides an anti-corrosion pot and a preparation method of the anti-corrosion pot. The anti-corrosion pot comprises a base body layer and an anti-corrosion layer, wherein the base body layer comprises a first surface; the anti-corrosion layer is arranged on the first surface, and the anti -corrosion layer is formed through a solid-phase reaction method. The anti-corrosion layer is formed on the surface of the base body layer of the pot through the solid-phase reaction method, through solid-phase reaction and through the high-temperature sintering method, particle rearrangement, material transfer, gas filling and grain growth among the elements of the anti-corrosion layer are formed, thus the finally formed anti-corrosion layer is uniform and homogeneous in ingredients, no potential difference exits, the pitting perforation phenomenon caused to a rust-proof iron pot after nitridation and oxidation treatment can not occur, meanwhile, the anti-corrosion pot has the advantages that the hardness is high, the wear resistance is strong, and the corrosion resistance is good. In addition, the formation of the anti-corrosion layer by adopting the solid-phase reaction method ishigh, and thus the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of cooking utensils, in particular to an anti-corrosion cooking utensil and a preparation method thereof. Background technique [0002] At present, there are two main treatment processes for anti-rust iron pans on the market. The first is to carry out nitriding and oxidation treatment, and the second is to carry out aluminizing treatment. [0003] (1) Nitriding and oxidation treatment: place the iron pot to be nitrided in a nitriding furnace under vacuum conditions, and pass a certain amount of NH 3 , and heat up to 600-700 degrees, and keep it warm for a period of time, so that NH 3 It is decomposed into N atoms and H atoms, and N atoms react with Fe atoms on the surface of the iron pan to form an iron nitride layer with high hardness and strong wear resistance on the surface of the iron pan. The nitriding treatment takes 6-8 hours in total, and the corrosion resistance of the iron nitride layer is not good. At th...
