Embodiment 1

[0055] like figure 1 As shown, Step1: Degreasing and degreasing the titanium substrate, sandblasting, thermal calibration, acid etching, and preparing the titanium substrate for painting.

[0056]Step2: Accurately weigh 0.427g RuCl 3 ·3H 2 O, dissolved in a mixed solvent of absolute ethanol and ethylene glycol (V 乙醇 :V 乙二醇 =9:1), stirred at room temperature until completely dissolved to form solution A; added 1.6762 g of butyl titanate and an appropriate amount of concentrated hydrochloric acid (volume ratio 10%) to solution A, stirred at room temperature until completely dissolved to form a solution B; Save for later use.

[0057] Step3: Apply solution B evenly on the treated titanium substrate, let it dry naturally for 2 minutes to spread the coating evenly, place it in an oven at 120°C to completely evaporate the solvent, then place it in a sintering furnace at 450°C, and sinter for 10 minutes , take it out, and let it cool down to room temperature naturally. Repeat t...

Embodiment 2

[0059] refer to figure 2 , Step1: Degreasing and degreasing the titanium substrate, sandblasting, thermal calibration, acid etching, and preparing the titanium substrate for painting.

[0060] Step2: Accurately weigh 0.427g RuCl 3 ·3H 2 O, dissolved in a mixed solvent of absolute ethanol and ethylene glycol (V 乙醇 :V 乙二醇 =9:1), stirred at room temperature until completely dissolved to form solution A; added 1.6762 g of butyl titanate and an appropriate amount of concentrated hydrochloric acid (volume ratio 10%) to solution A, stirred at room temperature until completely dissolved to form a solution B; Save for later use.

[0061] Step3: Apply solution B evenly on the treated titanium substrate, let it dry naturally for 2 minutes to spread the coating evenly, place it in an oven at 120°C to completely evaporate the solvent, then sinter it in a sintering furnace at 350°C for 5 minutes, and then Place it in a sintering furnace at 450°C, sinter for 5 minutes, take it out, and...

Embodiment 3

[0063] Step1: Degrease and degrease the titanium substrate, sandblasting, thermal calibration, acid etching, and prepare the titanium substrate for painting.

[0064] Step2: Accurately weigh 0.427g RuCl 3 ·3H 2 O, dissolved in a mixed solvent of absolute ethanol and ethylene glycol (V 乙醇 :V 乙二醇 =9:1), stirred at room temperature until completely dissolved to form solution A; in solution A, add 1.6762g butyl titanate (n Ru :n Ti =1:3) and an appropriate amount of concentrated hydrochloric acid (volume ratio 10%), stirred at room temperature until completely dissolved to form solution B; 0.0129g WCl was added in solution B, stirred at room temperature until completely dissolved to form solution C, preserved ,stand-by.

[0065] Step3: Apply solution B evenly on the treated titanium substrate, let it dry naturally for 2 minutes to spread the coating evenly, place it in an oven at 120°C to completely evaporate the solvent, then sinter it in a sintering furnace at 350°C for 5 m...

Abstract

The invention relates to a preparation method of a titanium anode for water treatment. The preparation method specifically comprises the following steps: carrying out pretreatment on a titanium substrate; preparing an active coating solution; and performing sintering. WO3 which is good in chemical stability, has catalytic activity and is low in cost is introduced into a traditional ruthenium-titanium active component, the service life of the anode is effectively prolonged, and the manufacturing cost of the anode is reduced.

Description

technical field [0001] The invention belongs to the field of electrode materials, in particular to a method for preparing a titanium anode for water treatment. Background technique [0002] In the electrochemical industry, the active electrode is its key component. The composition and structure of the electrode material determine its electrochemical activity and stability. In 1965, Beer first developed a ruthenium dioxide coated anode, which opened up a new generation of anode materials. The presence of the coating endows this type of anode with high chlorine evolution activity, where Ru 4+ and Ti 4+ The ionic radius is almost the same, so it can form TiO 2 For the solid solution RuO of the structure 2 -TiO 2 / Ti metal oxide coated anode, after a lot of research, in the active coating, RuO 2 +TiO 2 The composite binary oxide has superior comprehensive performance and is the most commonly used coating material in the chlorine analysis industry. The ruthenium-based coate...
