Abstract

The invention discloses an acid-resistant and alkali-resistant pure titanium composite pot and a processing method thereof, and relates to the technical field of pot body preparation. The method comprises the following steps: treating a titanium plate with mixed acid, carrying out electrocorrosion to prepare a pretreated titanium plate, reacting the pretreated titanium plate with a mixed sol cylinder to prepare a modified titanium plate, preparing potassium tetratitanate from potassium carbonate and titanium dioxide, carrying out a mixed reaction on the potassium tetratitanate and urea, carrying out a mixed reaction with graphene oxide to prepare modified graphene, mixing the modified graphene and liquid paraffin, and then smearing mixed paste on the surface of the modified titanium plate,and performing compression molding after high-temperature treatment so as to obtain the acid-resistant and alkali-resistant pure titanium composite pot. The acid-resistant and alkali-resistant pure titanium composite pot prepared by the method has excellent acid resistance and alkali resistance.

Description

technical field [0001] The invention relates to the technical field of pot body preparation, in particular to an acid and alkali resistant pure titanium composite pot and a processing method thereof. Background technique [0002] At present, there is a kind of real stainless iron pan that has been nitrided on the market. This type of iron pan is formed by cold stamping of low-carbon steel plate or cast iron. After the inner and outer surfaces are polished, they are nitrided and oxidized. Treated to prevent rust. [0003] However, the nitrogen-treated real stainless iron pans on the market have poor acid resistance, and are not resistant to the corrosion of acidic foods with a pH value of less than 7, such as vinegar and sauerkraut, during cooking. During use, pitting corrosion is prone to occur on the part of the inner surface of the pot that is in contact with food, forming trachoma, which eventually leads to perforation of the pot body. Moreover, the surface structure of...
