AI Technical Summary

Technical Problem

During the production of electrolytic foil, defects can easily occur on the foil surface due to reduced speed and load, especially the problem of foil widening.

Method used

The hydration treatment method includes boiling, spraying, heat preservation and filtration steps. The foil surface is kept moist and warm by adjusting the liquid level and tension of the pure water in the boiling tank. The water temperature is maintained by using a stainless steel tank and pump body. The height of the bottom roller hanger is adjusted by using a tension sensor and electric lifting structure to avoid foil surface defects.

Benefits of technology

This significantly reduces the problem of foil widening caused by reduced speed and load during peak power production of high-voltage electrode foil, ensuring the production quality of the electroformed foil.

Abstract

The invention discloses a hydration treatment method for medium-high pressure formed foil production in the technical field of formed foil production, which comprises the following steps: S1, water boiling treatment: carrying out liquid level lifting treatment on pure water in a water boiling tank; s2, spraying treatment, wherein after the liquid level is lowered, the foil surface is subjected to spraying treatment; s3, heat preservation treatment: carrying out heat preservation treatment on the discharged pure water; s4, filtering treatment: filtering the heat-preserved pure water when the pure water is pumped back to the water boiling tank; in the hydration treatment process of the formed foil, the defect that the foil surface of the pure water is widened after the vehicle speed is reduced is overcome, and the problem that the foil surface of the high-voltage electrode foil is widened due to speed reduction and load reduction during power peak-avoiding production is remarkably solved by adjusting the soaking height of the pure water in the water boiling tank and adjusting the operation time of the etched foil in the water boiling tank.
