AI Technical Summary

Technical Problem

Existing continuous tin-plating strip processing equipment is difficult to ensure uniform mixing of the tin-plating strip surface and the passivation solution, resulting in insufficient uniformity and consistency of the passivation treatment, affecting the surface quality and performance of the product.

Method used

By introducing the coordination of components such as motors, rotating rods and stirring rods into the passivation mixing equipment, the tin-plated strip is fully mixed with acid solutions such as organic acids, inorganic acids and phosphorus compounds. Combined with the design of automatic water flushing equipment, it is ensured that the acid solution evenly covers the surface of the tin-plated strip, and the residual acid solution is removed by automatic flushing.

Benefits of technology

The uniform mixing of acid on the surface of the tinned strip and the uniformity of the passivation treatment are achieved, which ensures the stability of the product surface quality and performance, avoids the adverse effects of acid residue on subsequent processes, and prevents corrosion.
