The inner lining of the capacitor cover of wet acid production technology is manufactured using modified fluororesin resistant to concentrated sulfuric acid as the main material. This material withstands temperatures up to 150°C, has excellent aging resistance and impermeability, which allows it to resist corrosion of concentrated sulfuric acid and the impact of working conditions for a long time.
At the processing stage, the rotating spray molding technology is used, providing a complete one-time molding of the inner lining – after molding, its surface remains smooth and flat, and the layer thickness stably reaches 0.8 mm. At the same time, the material has an exceptionally strong adhesion to the base of the cover, thanks to which in the process of long-term operation the possibility of layering is excluded, which guarantees the tightness and safety of the equipment.
