preparation example Construction

[0028] The method for preparing the above-mentioned anode according to an embodiment, the method includes the following steps:

[0029] S1: Pretreating the titanium substrate to obtain a pretreated titanium substrate.

[0030] Wherein, the pretreatment may include sandblasting. The roughness of the surface of the titanium substrate can be increased by sandblasting, which is beneficial to improving the adhesion of the composite oxide layer on the surface of the titanium substrate. The blasting material used in the blasting treatment may be corundum or quartz sand, for example.

[0031] S2: Etching the pretreated titanium substrate in an etching solution to obtain an etched titanium substrate.

[0032] Wherein, the etching solution may be selected from at least one of oxalic acid solution and hydrochloric acid solution. Further, the concentration of the oxalic acid solution may be 20% to 50% by weight, and the concentration of the hydrochloric acid solution may be 10% to 30% ...

Embodiment 1

[0046] The titanium plate was sandblasted, then etched in an oxalic acid solution with a concentration of 20% by weight at 80° C. for 30 min, and then cleaned with pure water. Dissolve tin chloride, ruthenium chloride, manganese chloride, butyl titanate and nickel chloride in ethanol to obtain a mixed solution, wherein, Sn:Ru:Mn:Ti:Ni (molar ratio)=320:12: 1:4:10, the weight ratio of the total weight of tin chloride, ruthenium chloride, manganese chloride, butyl titanate and nickel chloride to ethanol is 1:5. The mixed solution was coated on the surface of the titanium plate, dried at 120°C for 10min, and then fired at 450°C for 1h. Repeat coating, drying and firing under the above conditions for 4 times, the last firing temperature was increased to 600° C. and fired for 3 hours to obtain the anode prepared in this example.

Embodiment 2

[0048] The preparation steps of the anode in this embodiment are roughly the same as those in Embodiment 1, except that in the mixed liquid, Sn:Ru:Mn:Ti:Ni (molar ratio)=400:15:1:5:12.

Abstract

The invention relates to an anode used in electrolyzing water to generate ozone, a preparation method and application thereof, an ozone generating system and a dental cleaner. The anode comprises a titanium substrate and a composite oxide layer attached to the surface of the titanium substrate, the material of the composite oxide layer includes a metal oxide, and the metal elements in the metal oxide include tin, ruthenium, manganese, Titanium and nickel, the molar ratio of tin, ruthenium, manganese, titanium and nickel is (200-500):(2.5-20):1:(1.5-7):(5-15). The anode of the invention has a special composite oxide layer, and can output ozone water with an ozone concentration of 0.1mg / L-0.6mg / L in a stable and controllable manner in the process of electrolyzing water to produce ozone.

Description

technical field [0001] The invention relates to the technical field of ozone generation, in particular to an anode used in electrolyzing water to generate ozone, a preparation method and application thereof, an ozone generating system and a tooth washer. Background technique [0002] Using ozone water to rinse teeth or perform oral care can quickly and effectively kill virus bacteria and harmful microorganisms such as tuberculosis, Escherichia coli, gonorrhea, typhoid bacillus, etc. The electrolysis of water ozone technology has the advantages of low voltage and no harmful by-products. Its principle is to use DC voltage to electrolyze water to generate ozone at the anode. However, the disadvantage of this method is that it is difficult to controllably generate an appropriate amount of ozone. When using this technology to generate ozone water to rinse teeth, it is impossible to maintain a stable bactericidal effect. Contents of the invention [0003] Based on this, it is n...
