1. Activated Cathode ChamberFor the diaphragm cell, its cathode mesh is constructed by perforated SUS316L ultra-low carbon stainless steel, and the perforation ratio is 38% or so. On the other hand, the high temperature alkali corrosion technology is applied to remove Cr, Fe and others from the surface of the stainless steel, forming a porous surface that is rich in Ni.
    1. Expandable AnodeAll the heating devices adopt computer-aided temperature control technology, and the automatic multi-head welding machine, which is exclusive in China, is used to finish spot welding process for the mesh. Moreover, the flat spring is fabricated by high quality Ti material that is imported from Japan, and it can still expand evenly after long-term service.

Diaphragm Cell with Metal Anodes

The diaphragm cell with metal anodes has some outstanding features, and it is widely accepted on the world market.

1. The cathode adopts improved mesh manufacturing technique, and it shows the advantages of smooth surface, no blocked holes, uniform ion absorption, etc. Thus, it is applicable for working conditions with a small electrode distance and a high electric current, and it also realizes good energy conservation effect. In addition, this structure has gained the national invention patent.
2. The copper busbars and the chamber are combined together via automatic submerged arc welding process, and this welding process is characterized by deep fusion, high strength of weld seam, little damage to cathode chamber, etc. After welding, photoelectric tracking technique is applied to further ensure the welding quality.
3. For this diaphragm cell, when the cathode chamber reaches its life span, the copper busbars could be recycled to make a new cathode chamber. From this point of view, the service life of cathode is prolonged, and the maintenance cost is also cut down.
