This invention belongs to the field of polymer coating preparation technology, and discloses a method for preparing and applying a rare-earth modified graphene coating for electromagnetic wave shielding. First, rare-earth functionalized graphene is prepared using an electrochemical exfoliation method. Then, waterborne polyurethane resin is synthesized. Next, the rare-earth functionalized graphene, waterborne polyurethane resin, and water are uniformly mixed, and leveling agents, defoamers, and thickeners are added. Finally, the mixture is passed through a nylon mesh to prepare the rare-earth modified graphene coating. This invention achieves the following beneficial effects: coating an aluminum substrate with the rare-earth modified graphene coating of this invention imparts high battery shielding efficiency to the substrate, with an electromagnetic shielding efficiency greater than 40 dB in the 8–12 GHz (X-band) range.

This utility model discloses an offline material replacement blast furnace gas desulfurization system, comprising a dechlorination purification unit, a hydrolysis purification unit, and a desulfurization purification unit arranged in series along the gas flow direction. The key feature is that each purification unit has at least one fixed packing purification area within its outer shell. Within this area, horizontally arranged flow-around baffles are further provided, arranged in three alternating rows along the horizontal direction and uniformly along the vertical direction. The flow-around baffles on the left and right sides and the middle flow-around baffle are staggered vertically. This utility model is a blast furnace gas desulfurization system based on a fixed packing bed structure, capable of adaptive adjustments according to different stages of the packing's service life to improve purification efficiency and packing utilization efficiency. It is particularly suitable for the production needs of small enterprises with low throughput requirements.
