Problems solved by technology

However, due to the instability of fluororesin processing, coupled with the low hardness of fluororesin itself, relatively short service life, and easy to fall off, it is not resistant to high temperature, especially fluororesin will decompose carcinogens at high temperature etc. These problems have brought great inconvenience to manufacturers and users

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] see Figure 1-2 , the aluminum cooking utensils and their surface treatment process, the stamped pure aluminum or aluminum alloy utensils 1 are subjected to surface sandblasting pretreatment: coarse steel grit, steel balls, steel wire grains, or the three can be used Mix and blast the surface of the container with high-pressure impact to produce concave holes with different diameters or depths, unevenness and uneven thickness. The surface treatment can also be chemical etching, such as immersing the vessel in a solution of trisodium phosphate. Then, set the surface area to 4.8m 3 The container is connected with pure titanium as the anode, and the cathode is made of copper or lead, and placed in a 10m 3 In the acid solution, the acid solution is sulfuric acid, oxalic acid or a mixed acid thereof, and its working temperature is 5°C to 20°C. The...

Abstract

The present invention is aluminum made cooking utensil and its surface treatment process. Punched and surface-pretreated aluminum or aluminum alloy utensil is anodized through connecting with titanium anode, setting inside acid solution with copper cathode and leading DC plus pulse current, so as to form one layer of hard titanium-containing oxide film; and then, the oxide film is covered with one non-sticking layer. The titanium-containing oxide film has high wear resistance, powerful anticorrosive property and high hardness of HV1200-1500 on aluminum or HV400 on aluminum alloy.

Description

technical field [0001] The invention relates to an aluminum cooking vessel and its surface treatment process. Background technique [0002] It is well known that titanium element will emit a kind of far-infrared rays when it is heated. When it is used in cooking utensils, it can heat the food inside the utensils; It can be heated evenly, and at the same time, it can also solve the disadvantages of the rice being sandwiched. [0003] In order to achieve this goal, most manufacturers use a method of adding a certain amount of titanium to the non-stick coating of the vessel, that is, the fluorine resin layer. This is what we currently see in the market. Infrared titanium coating. However, due to the instability of fluororesin processing, coupled with the low hardness of fluororesin itself, relatively short service life, and easy to fall off, it is not resistant to high temperature, especially fluororesin will decompose carcinogens at high temperature etc. These problems have...
