AI Technical Summary

Technical Problem

Existing electronic signal shielding rooms are inadequate in terms of impact resistance, electromagnetic shielding continuity, door and window joint protection, and on-site assembly precision control, making it difficult to meet the protection requirements of high-risk environments.

Method used

The wall panel module adopts a multi-layer composite structure, including a ceramic composite impact layer, a ribbed steel plate load-bearing layer, a honeycomb buffer layer, and an electromagnetic shielding layer. Combined with a hydraulic locking mechanism and conductive sealant, it forms a closed shielding layer, which enhances the resistance to bullet penetration and electromagnetic shielding performance. The hydraulic locking mechanism enables rapid assembly.

Benefits of technology

It enhances the shielding room's resistance to bullet penetration and electromagnetic shielding integrity, simplifies on-site construction processes, improves structural reliability and assembly efficiency, and meets the needs of high-risk environments.
