Title: Xiaohan Xu and a Tinplate Manufacturing Method

Introduction

Xiaohan Xu is an inventor associated with Suzhou, China. Her listed patent concerns a manufacturing method for tinplate, a steel product used in applications that require a protective tin coating. The method addresses several production stages, including flattening, electroplating, and passivation.

Latest Patents

Xu is credited with 1 patent: “Manufacturing Method for Tinplate.” The disclosed process uses two stands to flatten the base plate. The first stand has working rollers with a surface roughness of Ra 1.6–1.7 μm and a rolling force of 5,000–6,000 kN, while the second uses rollers with a surface roughness of Ra 0.5–0.6 μm and a rolling force of 3,000–4,000 kN.

During electroplating, the method specifies a tin concentration of 14–19 g/L in the plating solution. For passivation, it specifies a solution temperature of 41–43°C, a pH of 4.4–4.6, and a concentration of 16–18 g/L, with a passivation electric charge density of 120–180 C/m. Together, these parameters describe a controlled approach to producing tinplate.
