AI Technical Summary

Technical Problem

The existing domestic hole-filling slurry has a gap with similar foreign products in terms of process adaptability, stability and hole-filling effect, and is prone to problems such as hole leakage, uneven filling and hole-filling and plugging of the web due to changes in equipment, technology and environment.

Method used

An organic carrier is provided, including organic solvents, organic resins and organic additives, and a pore-filled slurry with strong broad suitability and good stability is prepared by specific component ratios and preparation methods. The pore-filled slurry consists of an organic carrier, inorganic powder and metal powder, and has good fluidity and filling effect through grinding and rolling processes.

Benefits of technology

The wide applicability and stability of the hole-filling slurry is achieved, and the poor hole filling problems caused by changes in equipment, processes and environment are avoided, ensuring consistency and quality improvement of hole filling effect.
