Production Process For Titanium Anodes

Titanium Anode Production Process:

First, sort:

1, according to the requirements of the customer's drawings, select the relevant brand and specification materials.

2, choose the right material to reduce the loss.

Titanium mesh: there can not be broken wire, broken roots appear.

Titanium plate: it is better to choose a relatively flat plate for the plate type, and at the same time, pay attention to the surface can not have peeling, delamination, cracking and other defects.

Secondly, feeding:

1. Determine the shape, quantity and quality of the material from the whole or a batch of material

2. After selecting the material, according to the drawing, make a certain shape, quantity, marking and punching. Whether it needs to be sanded or not, it must be operated strictly according to the drawing.

3,Feeding material should have accuracy.

Third, welding:

The welding of titanium material mainly uses argon arc welding. Only the same material can be welded together. The welding method of plate and tube is fixed by spot welding first, and then full welding. The welding of the mesh can use electric welding.

Fourth, sandblasting:

1. A process in which sand is blasted onto the surface of a titanium substrate by means of a sandblaster powered by compressed air. The sand is sprayed onto the substrate for impact grinding to remove surface impurities, noise and oxidized layer. At the same time, the sand blaster roughens the surface of the titanium substrate to improve the effective contact area of the titanium surface and enhance the adhesion of the coating to the surface.

2, sandblasting points, spray pits, pockmarks should be uniform, can not miss the spray.

Five, pickling:

Pickling process pickling solution is generally a mixture of various acids, mainly sulfuric acid, nitric acid and hydrofluoric acid, etc., these mixed acids have a strong corrosive, while having a strong oxidizing, high corrosive medium temperature, which puts forward a very high demand for corrosion corrosion-resistant materials. Pour oxalic acid into boiling water in a certain proportion, and put the substrate into the boiling pot to boil and brew.

Sixth, annealing:

1, annealing is a metal heat treatment process in which the metal is slowly heated to a certain temperature and kept at a certain temperature for a sufficient period of time, and then cooled at a suitable rate.

2, annealing can make has been deformed plate (net) to restore the original state.

3,Place the plate (web) on a very thick steel plate that requires straight edges. Place another piece of the same steel plate on the plate (net) and tighten it diagonally. The next two steel plates are completely pressed on the middle plate (net). After that it is sent to a furnace with a temperature of about 500°C for heating and calibration. Holding for 2 hours after a certain time.

VII.Dosage:

Precious metal solutions are configured according to the actual needs of the customer. Usually, the dosing solution is prepared the day before the planned brushing layer, because the prepared liquid must be air-cured for a certain period of time before it can be used.

Eight, drawing, baking, oxidizing

1, the prepared precious metal liquid with a brush on the substrate, and dry in the drying oven, so that the liquid can be quickly combined with the substrate.

2, the first five times the brush, the liquid can be re-coated and can fill the surface of the substrate. The back need to brush less liquid, so that the liquid brushes more evenly, but also can cover the front brush place, make the coating beautiful.

Nine, inspection:

Not only the production process is monitored in real time, after the production is completed, the number of products and specifications need to be checked again.
