[0021] The antibacterial test data of its antibacterial layer 2 is as follows;

[0022] Bacterial growth was evaluated as follows; 0-no growth, no mold growth on the material; 1- trace growth, scattered, sparse or very localized mold growth; 2- Mild growth, the mold spreads intermittently on the surface of the material or the colonies are loosely distributed, or the hyphae extend continuously on the entire surface, but the surface of the material under the mold is still visible; 3-Moderate growth, mold growth is large, and the material may show visible structural changes; 4-Severe growth, heavy mold growth; The culture time is 28 days.

[0023] The aluminum plate 3 is made of high-quality metal aluminum plate, which has a good metallic texture and can improve the overall quality of the material.
