How does Taiyangji coat?

[ Information dissemination:This station | Release Time:2018-04-16 | Number of views:618 ]

(1) Apply the coating liquid to the surface of the titanium Matrix, usually by brush, but also by electrostatic spraying, roll coating.

(2) Drying, each time applied in red lamp, or far red lamp baking temperature is generally 1001,200 ℃, let the solvent volatilization. The drying process is to wave out the solvent, if volatilization is not complete, with human heat oxidation process, will affect the coating adhesion and electrochemical properties.

(3) Thermal oxidation, calcination of 1015 min at specified temperatures in a heating furnace. The thermal oxidation temperature is too high, on the one hand, the chlorine content of the coating is reduced to very low, and the conductivity of the coating is deteriorated. On the other hand, by making the oxide crystals larger and the grains larger, the coating

The decrease of the binding force makes the electrochemical properties of the product deteriorate.

The thermal oxidation temperature is too low, the oxidation is incomplete, the binding force is poor, and the required electrocatalytic performance is not obtained.

The oxidation temperature affects the structure, composition and properties of the coating. RuO2 and TiO2 solid solution can be obtained at above 400 ℃.

When the coating is platinum group metal oxide, such as RuO2, the heating atmosphere must be oxidized and the reducing atmosphere is not suitable.
