Embodiment Construction
[0014] Preparation method of titanium-tantalum-platinum composite plate for ammonium persulfate, finished product size: titanium plate thickness 1.5mm; tantalum plate thickness 0.2mm; platinum foil strip size: δ0.02×3×L.
[0015] 1) The surface of the pure titanium plate of δ3×800×1000㎜ and the tantalum plate of δ0.8×800×1000㎜ are polished, and the surface roughness Ra is 0.5μm~10μm;
[0016] 2) Then place the tantalum plate on the top of the titanium plate, arrange explosives evenly on the surface of the tantalum plate, and explosively compound the tantalum plate and the titanium plate to obtain a titanium-tantalum composite plate;
[0017] 3) Then use a heat treatment furnace to anneal the tantalum / titanium composite plate that has passed the ultrasonic flaw detection inspection. The temperature of annealing treatment is 500℃~650℃, and the annealing time is 1h~5h;
[0018] 4) After the annealed titanium-tantalum composite plate is trimmed, leveled, and straightened, it is t...

Abstract
The invention provides a preparing method of a titanium-tantalum-platinum composite plate for ammonium persulfate. First, polishing is carried out on the surface of a titanium plate and the surface of a tantalum plate; then a protecting layer is evenly painted on the surface of the tantalum plate; the tantalum plate is placed at the upper end of the titanium plate, then explosives are evenly arranged on the surface of the tantalum plate for explosion, a titanium-tantalum composite plate is obtained in a composite mode; after the titanium-tantalum composite plate passes ultrasonic flaw detection, the titanium-tantalum composite plate is placed into a heat processing furnace for being heated to the temperature of 500-650 DEG C, heat preservation is carried out for 1-5h, annealing treatment is carried out; the titanium-tantalum composite plate after annealing treatment is subjected to side cutting, leveling and straightening and then is subjected to rolling through a plate roller mill, a thin titanium-tantalum composite plate is obtained; finally a seam welder is used for welding a platinum foil strip on the surface of the tantalum plate of the thin titanium-tantalum composite plate in a roll-welding mode, and the finished titanium-tantalum-platinum composite plate is obtained. The preparing method mainly solves the problem that after tantalum and platinum foil are combined, the platinum foil can easily fall off, and meanwhile the service life of the composite plate in ammonium persulfate is prolonged.
Description
technical field [0001] The invention belongs to the technical field of plate preparation, and in particular relates to a method for preparing a titanium-tantalum-platinum composite plate for ammonium persulfate. Background technique [0002] In the production industry of ammonium persulfate, tantalum-copper composite rods are often used as conductive materials in corrosive solutions. Tantalum has good corrosion resistance and protects copper with good conductivity. It is a kind of metal with good comprehensive properties. Conductive materials are widely used in chemical industries such as chlor-alkali and electroplating. However, when platinum is welded on the rod-shaped electrode, the platinum and the rod-shaped electrode are in line contact, and it is easy to fall off in the electrolytic cell. In addition, when the rod-shaped electrode is used, Usually a long row hangs together and sinks into the electrolytic tank. When one of them has a problem and needs to be overhauled,...
