Problems solved by technology

[0002] With the continuous improvement of science and technology, titanium-palladium alloys are used more and more widely. At the same time, due to the high price of pure palladium in the field of hydrogen production, titanium-palladium alloys have been slowly used instead of pure palladium to produce hydrogen. , but the titanium-palladium alloy in the prior art is easily oxidized during the storage process, thereby forming an oxide film on the surface of the alloy, which not only reduces the service life, increases the cost consumption, but also affects the high-efficiency production of the titanium-palladium alloy.

Abstract

The invention discloses an antioxidant treatment process of a titanium palladium tube. The antioxidant treatment process mainly comprises the following steps of degreasing, primary cleaning, antioxidant treatment, secondary cleaning, blow drying and drying. Acetone cleaning is adopted in the primary cleaning, and according to antioxidant treatment, the titanium palladium tube is put into an antioxidant solution to be soaked, and the antioxidant solution is formed by mixing 70% of pure water and 30% of an antioxidant; and the antioxidant comprises raw materials including, by weight, 25% to 40% of tocopherol, 24% to 30% of butyl hydroxy anisd, 12% to 20% of butylated hydroxytoluene and18% to 25% of sodium citrate. The temperature of the antioxidant solution ranges from 40 DEG C to 50 DEG C, and the soaking time ranges from 40s to 50s; and through the manner, the titanium palladium tube has the stronger antioxygenic property and is convenient to store and transport, the service life is prolonged, and the cost loss is reduced.

Description

technical field [0001] The invention relates to a treatment process, in particular to an anti-oxidation treatment process for a titanium-palladium tube. Background technique [0002] With the continuous improvement of science and technology, titanium-palladium alloys are used more and more widely. At the same time, due to the high price of pure palladium in the field of hydrogen production, titanium-palladium alloys have been slowly used instead of pure palladium to produce hydrogen. , but the titanium-palladium alloy in the prior art is easily oxidized during the storage process, thereby forming an oxide film on the surface of the alloy, which not only reduces the service life, increases the cost consumption, but also affects the high-efficiency production of the titanium-palladium alloy. Efficiency of pure hydrogen. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an anti-oxidation treatment process of titaniu...
